Okay, I don't know how I've never seen the kickstand bead break before, but that is way more value than I was expecting from a video about a terrible idea!
Again, car tires existed before motorcycle tires, and motorcycle tires came long after motorcycles. Unless you count the bicycle tires that OG motorcycles road around on as "motorcycle tires". Please, stop being childish about this topic. It's like believing "reefer madness".
watch the very last part of this video again. We all make compromises between comfort and safety, longevity and safety, expense and safety, style and safety... hell, even between different bike tires you have to make several compromises, so, "terrible idea"... as he said "let it go".
I've ridden darkside. I actually rode Darkside for over 5K miles, before lowsiding it in a curve one day. The handling characteristics are truly shit. That car tire will follow the contour of the road. I was riding interstate 200 miles a day, which is one reason I made it so many miles before crashing. Let me tell you, Darkside on the interstate is like sitting on the sofa, it is so smooth. It wants to stand straight up, allowing me to cross the entire Dauphin Island bridge with out touching the handlebars. On the other hand, i ran through some tiny pebbles in a curve one evening too fast. I had to "force" the bike to lean far enough, so far, in fact that the asphalt contacted my rear saddlebag, taking the weight off the wheel. I corrected by steering back toward the center of the road, that's when the tire got in its happy spot , back on the tread, going into the old "death wobble". During the extreme leaning, the engine guard had contacted the asphalt and wrapped around my right ankle, rendering me helpless as far as using the rear brake pedal. Long story short, i now can't kick the bike away from me, I'm attached by the ankle, lowsiding on the left side of the road between two street sign posts. That's when bike and I both went over the embankment, still attached to the 700lb beast. She flipped mid-air and flung me off. Came out out of that with three broken toes, and the toe burned off my right boot, oh, and a totaled bike. No more Darkside for me.
@@adilsonlegalyt9647 he said the tire caused wobble. I’m not an engineer but i kno tire geometry is very important on a bike. When you lean the bike on a square tire i imagine a sudden jump from the center line of the tire a couple inches over to the edge of the tire where the rounded front theres a smooth transition. Aside from the tendency for the bike to stay upright on the flat, when its at a 45 there is gonna be a mis alignment of the two contact patches by an inch or two i would think. The relation of the contact patches to lean angle, rake and trail are pretty delicate in my experience and designed so you can corner no handed if you want. A low rear changes it enough so that you have to counter steer just to keep the bike leaning in a corner.
So i cant imagine how terrible a square tire would handle. I worked at a bike and had a customer that rides all over the us on a gold wing and I think he said he put 30,000 and counting on a car tire i just cant imagine enjoying country roads like that. In saying that i cant remember what tire he used but from wat i can remember it was pretty specific
I appreciate 1. the flip phone 2. that your first ride was in the rain with just 'jeans' and not $1.2 million in Klim ultra armor 3. the flip phone 4. your willingness to work on a bike in hipster boots 5. the flip phone
Where I think this could be worthwhile would be on a sidecar combination. They're not supposed to lean into turns, so the square profile isn't a problem and in fact gives you a larger "footprint".
Americans in the comment section are like: „yeah, I have experience with car tires on bikes, it’s not optimal“ Europeans in the comment section are like: „YOU DID WHAT??????“
The non-motorcycle specific tire will hold just fine when you find yourself going faster than you should in a long, sweeping corner, with better traction should there be dust, dirt, and/or water on the road surface.
Maybe you should try it, you can't get the experience from a video. Been darkside for years with literally zero issues of handling. It's actually much more stable, even in corners
@@OldSchoolParatrooper If riding in a straight line but once you wish to corner then it would become more dangerous. If the rear square tyre forces you to keep applying steering input to the front as you lean over then that is taking away from what little front grip you have. This is same as braking and cornering at same time i.e. the braking force removes some of the grip available for cornering hence you are more likely to lose a front trail braking into a corner or too deep etc
Bad Idea...here's why...Front tire contact patch, about 1 1/4" wide. Rear contact patch, about 7", and that is where all the stability issues begin. If the LEFT side of that wide tire rolls over a high spot in the pavement, the bike tilts RIGHT!! and vice versa. If riding a "truck lane" and you get into one of those two valleys in the pavement that heavy trucks create, the bike constantly weaves back and forth, depending on which side of that wide tire makes contact with the slope of the valley. I always had to ride the center of the lane to avoid that weird greasy feeling. After about 3 months I drop kicked that tire into my garbage bin....never again!!!
@@stupollock6851 car tires on sidecar motorcycles is nothing unusual. even in the front. I don't know where you're from but here in Europe motorcycle tires on sidecar-conversions are relatively unusual.
jomcjay yes I have seen them when I was on the Isle Of Man. I’m not particularly fond of the look but on back maybe not as noticeable. I’m from Northern Ontario Canada and planning trip on ice road in far north. Just think bigger back tire let you haul more without sinking in snow. Plus added traction. Plus supreme wear and saving. I don’t know why they can’t make bike tires last longer.
@@stupollock6851 they can make bike tyres last longer, and they do. Back in the day I was lucky to get 3000 km from a Pirelli Phantom on a 60 hp bike before the cords showed. Now I get 18 000 km on a 75 hp bike and I change them when they're still legal. More than that may one day be possible, but right now it's a trade off between handling+grip vs life. There are some very flat, car like tyres that will get you 30 000 km, but they handle like shit, slide all over the place and are really hard to change. So people don't buy them. So they sell in small numbers. So they're expensive.
A few years back I bought a GoldWing that had a car tire on the back. Everything you said was valid. There was another issue that you didn't really cover. The hard rubber causes way less traction even in a straight line. The Wing would light up the tire every time I would accelerate, even with my wife on the back. It followed this up with locking up whenever the brake was applied. So, in addition to not cornering or going straight, it also couldn't accelerate or brake. But at least it would last the rest of my life. Just like a parachute that doesn't open.
The traction issue would be very dependant on the particular tire used, there are soft road car tires out there, there are also long lasting "eco" tires that don't grip for shit, so is the case for motorcycle tires really- many people would be better off with a soft car tire for commuting rather than a hard moto one.
@@piciu256 I got michelin road 5's and I swear it must be made of a cheese compound because I've picked out bits of glass and found another nail.. it's a road vacuum cleaner.
I use drag radials on the back of my V twin. Waaay more cornering traction than the michelin cruiser tire I had on it. I couldn't pull a wheelie before on the bike tire either. It just spun. Now it picks the front end up. You do have to countersteer in the corner, but the bead conforms to the motorcycle wheel much better than you're hearing here. There are no metal bands on the far inside lip of a car tire. That edge easily conforms to the inner bead of the bike wheel.
I have to say FortNine has kicked up the production value of it's videos, and I like it. The editing, videography, audio quality, dialog are all spot on. He could be talking about pants and it would be entertaining. The fact that it's about motorcycles is just a bonus. Keep up the awesome work!

Just... Just some of the best edited/filmed/shot/written and entertaining content on TH-cam (that I have come across). As both a motorcyclist and content consumer- Thank you for the time/effort you put into your work.
My 2006 Rocket III Classic was a great riding & handling bike with a 225/50R-16 Dunlop Direzza DZ101. Perfect match in all dimensions to the stock Metzler 240/50-16. The sidewall had the same rigidity, identical overall height and width, and it was a sticky performance tire. The tread was a sporty symmetrical & directional pattern with a rounded edge. I ran at about 25psi which resulted in smooth, stable, composed handling and MASSIVE traction advantage over the MT. The bead did not look any different than the Metzler either but I was not using a run-flat. I installed and balanced it myself. Trust me, the size & weight of that rim with brake rotor far exceeded any worries of unsprung weight. And yet, the Dunlop was fairly light as well. I had no vibes or gyroscopic tendencies at any speed. My bike would top out about 135mph - limited by the windshield, floorboards, and bags (and my fat butt). I scraped the boards frequently (thankfully they articulated). If blindfolded, one would only know it was a CT at walking speeds. Above that it was almost unnoticeable. Yes, a bit more counter steer was needed to initiate a lean but by the end of the first day riding you did it subconsciously. Grooved road surfaces didn't affect it much but I think that depends on the tread, pressure, and width mounted on each bike. For my bike/tire combo, it was well behaved, confidence inspiring, and FUN to drop clutch and peel out. No more applying throttle timidly while turning for fear of losing the rear. Nope. pour it on and leave a beautiful black arc behind. But before I have rotten vegetables heaved my way, yes, there are some drawbacks and you need to gauge your abilities. If you have even the slightest doubt, then by all means don't do it. Those of us who darkside don't just throw any POS tire on there. #1 - Darkside is not for all bikes. The GS is probably not the ideal candidate being so tall and narrow. Best left to heavy, lower, tire grinders like Power cruisers & touring bikes. #2 - Narrow rim & wide tire are not a good combination. DS works better on a wide rimmed bike. In this test a narrower tire (if even possible with the given wheel) would have produced better results. #3 - Tire pressure looked high and gave the impression the handling looked edgy. Inflation is key to good tread/sidewall compliance. Regardless, I thoroughly enjoyed the video and would say almost everything he said was correct.
holyy crap just saw it now :OOO i use mine for drifting and stunts so i go thru tires like 1 or 2 a week and i do them by hand ... this would have saved me soo much pain blood and time. gonna be trying this in about 2 or 3 days !!

I have to disagree with the "higher mileage" point. Having been turning wrenches professionally on bikes for 15+ years, I have changed thousands of tires in my career. Many were utterly destroyed car tires. The tread wasnt hurt hardly at all. Its the sidewall that takes the hit. When you put big fat bikes on a 2 square inch contact patch while cornering, rubber flexes. Being that the sidewalls are drastically thinner, they flex first. This will generate excessive localized heat and wear and will eventually appear as if something was jammed into the side of the tire and rubbed a groove into it for a few hundred miles. Ive physically seen the sidewalls fail and cause the bike to go down, which totals the bike. And get this, these tires only had a few thousand miles on them. Maybe its different in flat states without a single turn for hundreds of miles, but out here in east TN where the road maps look like a plate of spaghetti, darkside is a big hell no!
Every time a post like yours comes out, or like one I mention where a dude crashed twice on car tires, due to blowouts, I'm told to "prove it". It's funny how one side is believed, without comment, while another is disputed. Great comment.
@Wroger Wroger Another good point. Ill add that motorcycle tires work best and have the most traction when they are warm. They become more malleable and adhere to the road better compared to when cold. Car tires are designed to resist all heat buildup possible so they last longer and will NEVER benefit from the effects of a warm tire and will not have the same amount of traction as a real motorcycle tire.
There are sometimes blowouts with car tires, because run flat tires are run way too long without any air. They are so dang dependable that some folks think they can ignore routine PSI checks. However, a low tire sidewalls are MORE vulnerable upon the thinner motorcycle tire, and I've been guilty of ignoring them when I was young. Another neglect caused by car tires is the required maintenance on shaft drive bikes. The car tires last three or four times as long, so gears are neglected until they run dry and self destruct.
A flat state, and commuting 80 miles each work day, was exactly why I was considering them, but no car tire would fit the back of the Vulcan I had. I would have done it in a heartbeat to avoid changing out rear tires so much. The way I see it, I wouldn't do it for two bikes, but for a dedicated commuter or cross-country bike, sure.
I've darksided a GL for the life a tire, mostly through a very rainy winter in Portland, OR... it was good in snow, it was good in the rain, and it was good for towing a trailer. The tire didn't last much longer than an regular motorcycle tire, in a large part as I spend a lot of time on the sidewall. (I used to own and now occasionally teach for the Northwest Motorcycle School, where we taught a motor officer course to the general public, and much of our riding was full lock, full lean and below walking speed.) I simply wore the shoulders of the tire out, while the center tread was fine. I'm not teaching regularly now, and living in New Mexico, with it's mostly straight roads, I spend far less time on the tire's shoulder. I was looking into another darkside tire, when I noticed the weight difference. A car tire for the GL weighs between 9 and 11 Kg. (20-25lbs), while the motorcycle tires weigh around 3 Kg (according to manufacturers). That terminated my search, the durability might be great, but the added, un-sprung weight kills suspension response, and may have been a good portion of why handling "sucks." Yes, the bike understeers with the car tire, but, as noted in the video, it takes about 10 minutes to get used to keeping pressure on the bar while cornering. However, the tire's following of rough roads is severely compromised, particularly when leaned over. Just one more element to consider.
I'm on my fourth car tire on my Valkyrie. I crossed the country numerous times, and have over 80k miles DarkSiding. The only thing I've ever had to stomach are the nay sayers who feel their opinions trump facts.
@@MrJoshcornkid he does not say that it cannot be done as many crazy things can be done with a bike, just that it's not rational, secure and bright. That's why, like creationism, it's an US-only quirk that's made possible because of the fact that most of the US roads are straight lines and US riders are not so much in riding in twisties like in other parts of the world. Face it, like creationism, it is a religious issue and facts and science are never going to convince a darksider, just as they're never going to convince a creationist. :-)
Great video, interesting topic. My take on it.... I would never be a mooch and try to save a few dollars on a car tire when my motorcycle was designed by countless engineers to operate with the recommended rubber. I will stick with their recommendation, feel better about it, and I'm sure when I'm going around a corner well over 100 miles an hour I will feel a lot better with my motorcycle Dunlop Tire. Now do whatever you like.
This is one of the best darkside videos I have seen. It’s not arguing for or against but simply putting the information out there. We darksiders will never say that the handling is better than a motorcycle tire and we would put them on our track bikes just that for the riding we do they are perfectly adequate. I went to the darkside on my concours after replacing 4 rear motorcycle tires in one year. It’s not a track day weapon, it’s a touring pig.

@@hellomoto4240 yeah, I know...I was just referring to an old joke. A couple of tourists are lost in New York. They walk up to a guy carrying a guitar and ask him how to get to Carnegie Hall (a famous concert hall) and he replies "practice, man...just practice"
Pneumatic tires, such as those on a motorcycle, Do NOT behave as classical dry friction theory would suggest. Rubber generates friction in three major ways: a) Adhesion, b) Mechanical keying, and c) Wear Furthermore pneumatic tires are sensitive to load, as they are loaded up the coefficient of friction decreases. Reference: The Racing & High performance tire, Paul Haney, 2003 Or wiki, if you guys don’t want to buy the book above. en.wikipedia.org/wiki/Tire_load_sensitivity
Now I read that wiki page, and I have my B.ME working on my M.ME I know the other kinda forces. All this says is that it's not a component vector of dry friction but instead Coulomb's friction. This just means motorcycle tires get more grip in a turn since their sliding factor is more. Right the dry equation is simplified but is good enough. You do have only so much grip to go around, and the advantages of motorcycle tires is that you don't fight the tire in a turn, where as a car tire you do. You don't get enough grip back out of Coulomb's friction to make up that deficiency. Sure for F1 it's a serious concern and that's why we slightly camber those tires.
Okay i want to reply to myself now beacsue this comment made me very interested in that the actual formula is.

This shit is interesting and i kinda wish i did my masters in this instead
The tires being pneumatic vs solid has nothing to do with it. It is because a soft material (like rubber) on an abrasive surface (like pavement) has a coefficient of of friction that is itself a function of normal force. The equation ends up looking like F=z*N^s where 's' is usually around 0.95, but must be measured experimentally.
I absolutely love seeing a TH-cam comment debate with citations in place of curses, I'm glad to see fortnine cultivates a very friendly, non-toxic community
Besides the coefficient of friction of the rubber, there is the coefficient of friction of the pavement. In effect it is a combined coefficient of friction - of that tire rubber on that particular pavement. And oh yes, pavement friction varies depending on the aggregates it is made of and any polishing that takes place over time.
How can people give this video a thumbs down? F9 makes, in my humble opinion, the most entertaining, cool, educational motorcycle vids out there. Keep up the good work.
I normally like F9 videos and will continue to watch....but just too much incorrect information in this video and an obvious bias. Billions of miles people ride on car tires and didn't show proof of an accident or mishap caused by one. He used the wrong darkside tire with wrong pressure on the wrong bike....That's why I did. I've had numerous bikes and NEVER owned a Harley or a Goldwing...so NO...
@t c I got an apple watch for that. im not always taking my phone with me when I go out and people can still call and text me, and I can still use GPS but im not distracted by social media, fake news etc.
I put a Falken tire designed for the tuner market on my Honda VTX1800 and loved it. It was different from your choice in a couple areas. It has symmetrical tread, reinforced sidewalls, and rounded tread at the edges for better cornering. It did have better life and lower cost as you mention and better load capacity. What you didn’t mention was the better water handling capacity and the much better puncture resistance. I tested the tire with no air in it and it functioned for low speeds. Finally, when I had the second car tire put on the dealership called me and asked permission to cut the first car tire off the rim because it was so tightly fixed to the rim. The downside was low speed turning. You can definitely feel the bike as it transitions from the flat to side tread. I wouldn’t think of it on a sport bike but for a cruiser it was great. One last thing, My wife said the ride on the pillion was much smoother with the car tire. P.S. My original tire was tubeless and the rim geometry was not like what you show in the video.
@@julianbrelsford there are pictures of the contact patch of a car tire vs a motorcycle tire and the car tire actually has move contact area in a turn than a typical motorcycle tire. That is true for the ‘tuner’ marketed car tires that have geometry designed for drifting and high speed cornering. The contact area on a motorcycle tire is actually very small, but consistent no matter the lean amount. As I said in my original post, I would not recommend a car tire on a crotch rocket but for a 700+ pound dry weight cruiser it wasn’t a problem. Also, I added floor boards to both riding positions so the cornering angle was substantially reduced anyway. Even if the traction was equal, I was still comforted by the thick side walls and tread on the tuner tire that allowed the bike to operate with no air in the tire. Also, you can plug a car tire to get you home and that is highly discouraged with the light weight motorcycle tires with very thin tread area.
Just to clarify, contact patch has nothing at all to do with grip, as per Ryan's explanation. It is purely a function of how sticky the rubber is and how much force is being applied to it. The 'tuner' tire example likely has more working tread towards the edge of the tire, making it less sketchy for this use-case, but still sketchy considering how the car tire will always want to 'upright' itself after a few degrees of lean.
Its funny, i was just researching and watching videos about darksiding, and i noticed most of the users are cruiser riders. Really heavy bikes, without big lean angles. No suprise and your post confirms a lot for me
I own a street glide and some people recommend putting a car tyre on the back wheel . I can understand the cost part and mileage but if things go wrong your insurance is invalid ,you won’t get a MOT in the uk and the police will get involved. Personally I wouldn’t do it or recommend it either too many downsides.
@@johnludmon7419 In the US, at least, there is no such exclusion in a MC policy. And you are correct, my observation is many darksiders are cruisers and goldwing tourers who do not use the handling characteristics of a motorcycle.
I have two bikes darksided. Honda nc700x and triumph tiger 1200. It's amazing. I drive it like I stole it. It takes a few hundred miles to get use to. Once you do, you ride exactly the same. I have over 12 thousand miles on each tire. And. It's much better in the rain. I hope this helps. Try it you'll never go back.
Jim Gordon Not in the UK the bike would be illegal to use on the road. As I said in my post it would invalidate my insurance which would complicate things if I had an accident.

@@HalfCrazy520 I know a repair shop in my vicinity that used to modify car tires so they fit better on motorcycles, the place was shut down under claims that their work was putting people in danger, everyone who used them will say it was completely harmless as long as you didn't speed.

Universities in the US are mainly to generate revenues and keep incompetent 'professors' still employed and worse, you have the student shark loans, so in reality, if you want a good education, you have to be rich enough to go to some of the best private universities or study abroad, like in Germany or Canada.
Great info on the video! One thing I would recommend when inflating a tire on a rim it was not designed for is to put it in a cage or wrap a chain or ratchet strap through the rim and around the tire to contain it should the worst happen. If the tire blows off the rim when seating the bead, it could seriously kill you!😝
What do you think happens when a tire “blows off the bead?” Do you think it’s gonna fly across the building? Really? Do you? Think about what your saying. That tire was just put onto that rim, used some serious force to get it on too. Multiple steps, do you think the air pressure energy is Going to do all those steps, in an instant?
@@shelbystrong3663 Yes Shelby it has happened! My cousin got his jaw broken when a front tractor tire he was inflating blew the rim into his face. NOT a pretty sight.

I have been using Dunlop 185/65/16 car tire since 2006 on my VTX 1800 it took a little getting used too but you run tire pressure depending on the bikes weight I ran 34 PSI and it stuck like glue even in rain and tripled my tire mileage to 40,000 km

Darksiders chiming in. When the 1800 Wings came out, tire life of less than 10k was common, even 7k wasn't unheard of. Early on there were issues with tires delaminating due to underinflation and overloading. I was going through 2 rears and 1 front every year. I spent several days investigating everything I could find about darksiding. After all that and personal experience, this is what I concluded. The following link is my video with a camera under the bike. th-cam.com/video/qoNDo7o1d6Q/w-d-xo.html Not every tire works. Some designs work better than others. In my opinion, run flat tires are a must. The sidewall wraps around the rim and locks it in so we'll, that installation and removal is a bear. The rim profile mismatch is a fact, but the runflat sidewall locks onto the rim so hard, that I have to plan as much as 2 hours to change the tire when it's already off the bike. Handling is greatly effected by tire pressure. To high, and the tire doesn't flex enough. I run 25 psi cold and 30 two up, 34 fully loaded pulling a camper. Handling is different, but it's no problem to throw the bike around in the curves. The front tire effects the initial counter steering into a lean. When initiating a turn, I feel the front take the lead setting up for the banking turn. Once banked over, the bike will maintain it's lean angle. Even using cruise control in a curve, I can remove my hands from the bars and it maintains the bank. Off road traction is fantastic. I love riding dirt roads and trails. My current tire is a snow tire. I managed to drop my rear tire into a hole at a campground that the belly pan was on the ground while I had a trailer attached. The back tire climbed right out of the hole. I tested the run flat capability by removing the valve stem core and riding with zero air pressure. Normal riding was unaffected, while banking over just made the bike feel heavy. I was rear ended while having the car tire on. Progressive didn't care and even payed for a replacement car tire. Is darksiding for everybody, no. When properly installed and balanced ( I balance to + or - 1 gram ), using a tire pressure monitor ( you could get a flat and not know it ) and common sense, Darksiding works great. It's not something to just jump into. I respect the people who make TH-cam videos explaining the science of why it's not advisable. I understand the science, but I know how it works for me. As long as I'm riding my GL1800, it will never see a motorcycle tire on the back. Anytime we make modifications to our motorcycles, we have to accept that it's our responsibility for anything that might happen. I choose to run a car tire, and it's on me if anything ever went wrong.
Well written. In this case he installed a car tire on the wrong type of bike, rode it in the wrong kind of conditions and claimed it was wrong to do.

@@davemeise2192 He didn't say it is wrong to do so. He said you're lacking the built in saftety of the bumps locking the tire in, and because of this the tire COULD unseat itself. And then proceeded to tell you it's your own risk, without giving numbers as to how often this happens. And in doing so, he is 100% right. It does lack the safety features, and it COULD happen. You might go a 100 tires without it happening, and good for you. But he has to say this in order to make sure you understand how it works, and that it's your own risk. If he tells everybody to do it without fear and a tire does go wrong, he gets the blame. Simple.
Back in the mid 2000’s I did this on my 1800 Goldwing. I didn’t know about the bead differences. That aside the tire did work. After the scary first ride it was pretty normal except for the part about tracking on grooves in the road surface. Annoying at first but you get use to it. From what I remember the tire didn’t last that much longer than a good MC tire. The car tires wore out at the edges first. Both of them. I ended up going Back to MC tires after that. It just rides a lot better. Going back to MC tires felt like adding power steering.
I ran a GL1200 Goldwing with a side car and a car rear tire mounted perfectly. It ran great and I highly recommend it for sidecar applications. I tried it with the sidecar taken off the bike. On the highway I got in an absolutely terrifying tank slapper that is singularly the most frightening riding event of my 50 years of riding. I don't know how I did it (thank you guardian angels!) but I controlled it from a side to side, to the stops, tank slapper at 80mph (I know, I was pushing my luck). I sat on the grass at the side of the road for half an hour to get the adrenaline and heart rate down. I thankfully learned my lesson without loosing my life.
Maybe car tire applications on moto are for heavy weight moto, also tubeless tire is the way to stop Tire re-T900-coming-back to original form and fighting itself
I ran a car tire on a 650 Burgman for a few years without problems. Handling was as good as the OEM tire once I got used to the slightly different feel. Also of note was the much smoother ride, especially when the air pressure was around 32-34psi. More air and the bike rode more on the edge, making the bike feel squirrelly. Darksiding isn't for everyone.
Saw this on a goldwing just the other day.... needless to say your weight on the rear tire was seriously underestimated once I saw the couple whom it was come out of the restaurant. Great vid per usual!
I did this on a 1st gen Yamaha Vmax. It makes the deathtrap of a machine even more dangerous, but still awesome to ride. The flex of the huge sidewall added into the flex of the frame and suspension takes a lot of skill to maneuver. It also adds a "speed limiter" of sorts. When you get around 105mph the whole bike starts swaying side to side unless you back down on the throttle.
Thank You Sir for actually trying this out and showing how it can be done. And then giving us an honest, in depth, exactly right on presentation of how it works and the advantages and disadvantages of running a car tire. Your explanation about having constantly counter-steer thru a corner was very insightful!! The way a motorcycle handles does change for sure, but you get used to it. Certainly you wouldn't put a car tire on a canyon carving sport bike!! For a heavy touring motorcycle, the fact that a car tire lasts so much longer is a huge advantage. It certainly saves time and money!! Why spend a $150+ to have a rear tire replaced every 10,000 miles or so (usually less!!) when I can safely use a less expensive tire that lasts 3 times longer?? Also, having to replace a tire when on a long trip is not fun. For me, every rear motorcycle tire I have replaced is worn out in the middle and very little wear on the edges. So using a car tire is so much more convenient. This has been done for a long time as mentioned in the video. An older friend of mine said they used to lace up a 15" rim on their choppers so they could run a Volkswagen tire on the back. Using car tire works!! And for me there's no downside. And the fact is, people do this all the time. Thanks!
Yeah, seems like the car tire makes sense if you just commute or do lots highway miles. I know guys who replace their rear tire every year. Not to mention the cost of a puncture. That said, I'd probably try to find an inner tube that fits if I were using a car tire.
Thanks, Ryan. Very well done, as usual! I have had a Semperit M&S tire on the back of a Burgman 650 scooter now for 3 years. Works fine, EXCEPT: longitudinal seams in the pavement are downright scary! Leaned over traction is not a problem, since the giant scooter does not lean over very far anyway; parts drag right away. The M&S tire actually gives some traction; the stock tire gets stuck on wet grass. Still not sure about tire pressure; anywhere from 25 to 40 seems to work just fine. Please note that I am a dirt rider, and might not be noticing some of the nuances of pavement handling. Thanks again!
I mean, I work in tech yet I have a OnePlus 6 (not a bad phone when it came out but close to outdated by today's standards). Flip phone guys have a point. They never need software updates and the battery is almost always replaceable. If the battery in my phone goes bad it's likely going to cost more than the value of the phone to replace with an OEM part. This is by design.
@@marc-andreservant201 just fyi if you are okay with DIY look into ifix it. I replaced the battery for my 6t at one point for 50 bucks. If I ever need to replace it again it would be about 30 dollars because I don't need the tools anymore.
I use a Goodyear triple tread on the back of my Yamaha Stratoliner. I have used it for 4 seasons now. I did notice handling differences when doing heavy cornering. On gravel roads or uneven pavement you have to keep your wits about you. The tire does want to control the bike and get back to being straight up in those circumstances. Over all I am happy with the car tire and have 20000 km on it. I check the pressure regularly as we all should and ride. My advice for anyone thinking of going to the Darkside is do your research on type and quality of tire. I would not use it on anything but a big cruiser or tour bike. Sport, adventure, and other style of bikes I believe should stick to motorcycle tires. Great video.
I'm wondering what would happen, if you took a sidecar set up such as a Ural, and made it a darkside bike? The main problem with sidecars are that stability is a constant battle. But with your tires doing some of that work for you, would it make things easier?
I have a 85 Gold Wing 1200GL & Dark sided it with a Nexen 165/80/15 Cornering is no problem and now I have better braking, grip, water displacement and far better with a passenger + trailer. It also has an actual load rating...I'm staying on The Dark Side !.
I've been installling my motorcycle tires this way for about 10 years now. With most of them, I don't even need tire levers anymore. The zip ties are so slick after you get the beads to touch, you can stand on the tire and it just scoots onto the rim.
Been a Darkside Wing rider for two years and will never go back, the bike is just to heavy for motorcycle tires and cupping occurs, over 45 000km and still fine for 125$. Don't think i would use it on any other of my bikes though, can't feel much of a difference on the wing, your video quality is amazing as always
Baeng's Lobster (Wan Jtk) On my Goldwing, i would not advise trying it on a smaller nimble bike as it will take away from its performance, the Goldwing is over a 1000 lbs loaded and the rear wheel is better suited for the switch, i don't ride it like a sport bike like some Goldwing riders are know to do, so i can’t feel much of a difference at all
@@wanjtk if you want any fun riding don't ever do that. Modern motorcycle tyres are mostly all good, but I had a Honda cb500, limited to older models. Came with way to old not so good ones. Definitely felt a giant difference when getting better ones.
I'm not a biker. I was a motorcycle commuter. At 8000 miles it was time for my third rear tire. I put my first car tire on my kawa 900 lt. 25,000 later I bought another. At 50,000 miles the demands of having to pick up a grandchild at daycare for thr next 6 years meant I couldn't ride as much. 5 years and aound 55,000 miles later I worried more about the car tire rotting then anything else and it has mc tire on again. I did my 1000/1500 IBA ride on it, up pikes peak with it, oshkosh airshow with it rode as closer to the big mac bridge as weather and time would allow from parking lot practice to the occasional run up to 115 mph (Kansas tail wind and big shield helped a bunch fit the little bike). Mc tire feel better? Maybe. But 70 dollars for 3 years instead if 600 for 1,I didn't feel that much difference. Liability? It's dot rated, never caused a problem. Not for everyone? Ya. A solution for a problem? Yup.
@@justmyself1000 I've been doing on-and-off research on darksiding for twelve years and have read nearly a thousand NHTSA motorcycle crash reports, and have never found ONE where the primary- or even suspected- cause of the crash was a bead failure on a darkside (DS) tire. Plenty of drunk/impaired riding, lots of cars turning left in front of bikes, many excessive speeds, failures to negotiate turns, and even some tire failures (ALL of them motorcycle tires and often due to overloading or running underinflated), but nothing that would suggest DS is an unsafe practice. I have challenged the naysayers to provide ONE verifiable case of a crash or refusal of insurance claim due to DS, and have had ZERO takers. I've been riding the mountains of northern Wyoming for three years now on a V Star 1300 with a BF Goodrich, and it is a fantastic combination for comfort, durability, and safety.
Got to admit, when I first saw the slow-mo of him slaloming with the car tyre my first though was 'Oh, so this is how dies...' Genuinely surprised that actually worked in those conditions and for that distance. Still, I never cheap out on tyres unless I have to. Best advice I got was from an old instructor who said think of the physics - everything you do on the bike is theory; there are only two little patches where it becomes reality.
I've been darksiding my Goldwing for a couple years now. Since my ride is my primary mode of transport, I'm putting 30k miles a year on it. Motorcycle tires--$350 Goldwing tires--get expensive at that rate. It takes a few minutes of getting used to, but like he said, you don't notice after that. Never had any problems. In fact, where my motorcycle tires would sometimes spin in the wet under the fantastic torque load the Wing's car engine puts out, the car tires never do. I'm never going back.
It seems he chose the widest tire he could fit which which meant an extremely low profile sidewall, which affected his handling far more than necessary. I run a Sunfull SF-05 185/75R16 truck tire on my Gl1500, barely wider than stock, and I can't really tell the difference between it and the stock tire except for the weight of my wallet. A goldwing tire lightens my wallet to the tune of $200 or so, and this tire that will last 3 times as long for only $59.95 and free shipping off Fleabay! It does scrub my fender a little on bumps if I don't keep the shocks aired up to about 30lbs. The Spontaneous uninstallation.is a great line, but 4wheelers will deflate big tires down to 5psi for crawling over rocks and rarely have one deflate. Another plus that he didn't mention is that the light weight of a motorcycle will rarely push an object through the steel belt on the car tire. I went darkside on a Shadow 1100 because of picking up a nail at least once a month at the construction entrance at my job. Put 20k after switching and never had a flat again. I still picked up nails, but would hear them clicking and stop and pull them out. This bike rode much better, especially 2 up and was only a little loose feeling on gravel roads. Tire still had well over half it's tread left at 20k when I sold the bike.
I don’t how I haven’t seen this baby-faced scienctician before, but this single video garners an instant sub from me. You’re use of vernacular, and willingness to challenge ‘the norm’ are excellent. I look forward to perusing more of your videos!
Couple of extra added observations from my time trying the dark side on a GL1800. My car-tire did not last as long as the motorcycle tires I usually ride on. It provided more traction while leaned over than a motorcycle tire. I could give it full-throttle while leaned-over without losing traction. Full-throttle while leaned over with a motorcycle tire will cause my GL1800 rear-tire to lose traction and break lose. That said, the stand-up tendency was enough for me to not continue the practice.
You are the first to claim the MC tires outlast the car tires. You should list the brand and make of the tires you used because there's a lot of us here that ain't buying your claim.
@@wellsbengston4132 I don’t know Wells. While the Falken brand isn’t known for longevity, car drivers easily surpass 20k miles with them. There’s not a rear bike tire out there that will last 20k miles. I did have an Avon on a custom bike. It did last better than Dunlop or Michelins, but not close to a CT. I used a Toyo tire for 22k miles on HD. Still had plenty of tread. Now I have Pirelli Centurato run flat. Currently 15k and not even close to worn.
@@dougfresh1341 Keep in mind that I make it a point to spend as much time as possible on curvy mountain roads. I'm sure the tire would have lasted longer if I was a more typical Goldwing rider.
@@wellsbengston4132 Follow Yellow Wolf. He runs a Falken 612 non run flat. Rides a GW that puts sport bikes to shame. Still gets better service out of a CT. th-cam.com/video/37XLJNLpzxQ/w-d-xo.html&feature=share
One thing you're missing is that after 600 or so miles, the car tire "corners" "break in" to their new use, and the corners give while you take the curves. This gets better as the tire adjusts to it's use. Trust me. Darkside on my '98 Valkyrie. I was convinced by a madman from Dakota, in whose sagacity I believe. I'll probably never go back to a $400 rear motorcycle tire -- especially after the horrible experience of my last motorcycle rear, the Limey Venom, that was the worst tire I ever rode.
I am just about to mount new tires after literally shredding my rear tire to the threads 2 days ago. As a guy who lives for accelerating out of a tight twist but still rides a heavy cruiser, I was seriously considering switching up. After watching this presentation of the pros and cons I can definitely see that it's not for me.
Brilliant, as always! I see the comment regularly that this is the best Motorcycle related content on YT but after nearly exhausting your library I am convinced you have the best "Do-It-Yourself" content on the Inter-Web!

I'm on my third car tire on the rear of my 07 Goldwing. All 3 have been runflats. I have a total of 90,000 km's with car tires. My 3rd which is a Bridgestone has 20,000 km's on it and is good for at least another 20,000. Why? I can afford what ever I want. My observations are that the car tire has a far higher load rating, it's hugely superior in the wet,it lasts far longer,no one and I mean one one that I have heard of has had a "blowout"., the handling is suberb, braking is better, and lastly my wife says the ride is "plusher" Many thousands of riders have put millions of km's on bikes with car tires. I'll never go back to a MC tire. There is a web site called darkside info that lists the bikes and the recommended size of car tire. For my wing I use a 195/55/R16. Some guys will use the 60 series and or go up to a 205 width. I know riders who have used car tires on V stroms and FJR 1300,s. They too will not go back to MC tires.
i plan to one day get a goldwing and small trailer, either rv or just storage type. with two ppl plus a trailer it makes perfect sense to use a car tire on the back wheel. i just dont feel like a moto tire will handle that load for very many miles. no a car tire is not something id put on any sport bike. i just think of a car tire on that kind of bike to NOT be of much assistance to the performance of a sport bike. but a goldwing was not meant to out perform a sport bike. its was meant for a comfortable long heavy haul which is perfect for a car tire. plus even though they dont lean like a two wheeled bike, trikes use car tires on the back as well AND even the insurance companies have no issues with "the dark side" so long as its (here in the US) a tire approved by the D.O.T. like yourself, ive yet to see ppl who've tried the dark side to come away from it swearing up and down that it was the most dangerous thing they ever did. never seen statistics to prove so either. if there were, the insurance companies would forbid it in their policies and use it as an excuse to avoid paying out on claims.
@@rebel_ltz I've noticed that bmw cars handle and ride much better when they don't have super stiff, heavy run flats. They are factory installed on all none sport models. Also noteworthy, is that no sport models use run flats because the people that drive them usually don't have their head 5 miles up their posterior, like your average bmw suv driver. So I'd call run flats on a goldwing insane even if the gold wing has 2000lbs on the rear wheel.
Good post, David Giles! Same experience with me but on 5 different cruisers/touring bikes! I challenge anyone to find an accident or mishap caused by a darkside tire! WAY better traction in wet and braking! MORE precise in high speed curves. One needs to know how to ride and handle a bike. No "buts" or "ifs." I used more skinny car tires and with a more rounded profile than he shows in this video and usually spend around $70.00USD! His melodrama is laughable! One needs to find the right tire pressure as well! I've NEVER heard of a darkside tire coming off the bead!!!! Give us a break and qualify these claims! I wouldn't use that tire with that high pressure on a BMW adventure bike either!!...Get informed...
Darkside on my Goldwing, I pull a trailer with it and really like the run flat capability. The alternative is to buy a new rear tire every month if I go back to a motorcycle tire. I have not noticed any change in handling at all. Good video- i would say about 80% accurate.
I'm looking to get a used Goldwing and thought about doing this. I can't imagine dragging the foot boards on it, so this seems like a good, if not exactly proper thing to do. Can you tell me more about how you feel on yours?
@@Lightndattic a goldwing is pretty nimble. More than you would think for the size. I throw mine into corners without worry. Also has great power with a top speed over 130 mph.
Dude, that intro was straight fire! I don't think I've seen something so well put together. Who would have thought to put a low, bassy, sinister beat like that along a tire changing video? The lack of other sounds/vocals except for the extremely well-placed thunder at the end. Freaking masterpiece, man.
Colby Scott hell’s yeah bro. After watching the Ural review, started following the genius dude is the production genius behind the channel. findaneesh.com/
My inner engineer's skin is crawling. But if you just want to go and not worry about wild performance, go for it but all turns are at your own risk. You're a bright lad. You see the flaw already.
Wow. Perfect timing as usual! I've been looking for a Big Ruckus for a few years and found one modded with a fat car tire in the rear and considered not buying it because I wouldn't have the money to "un-mod" it for a while. I might risk it and see what it's like. I love that cooky scooty and I never see them for sale. Thanks again, as usual you are the pinnacle of educational motorcycle video essays!
@@16driver16 It's not just a tire. It's a full stretched and lowered mod, involving the suspension, engine casing, swingarm.. a ton of stuff. It's really not my style. I like the Big Ruckus how it is stock-ish. My plan was to raise it a bit and make a scooter scrambler for easy scooter camping. I can't take a dragged out, dropped scooter with 1in of clearance anywhere, much less off pavement or onto a light trail or fire road.... absolutely no way. My regular ruckus barely makes it and it has 3 times the clearance. lol
@@guerrillaradio9953 Oh hell yeah. You gotta get a bit creative with what you can pack, where you can ride, and how you make camp. I love it. I do wish I lived in a better place for it though, FL doesn't have many scooter/moto friendly campsites or parks. Hopefully if I can get a BR or a similar larger scooter it can open up a few more options for me.
@@DanteYewToob i get ya now, i dig it. Myself i want a regular ruckus and have the same problem with any even remotely cheap being stretched and somewhat heavily modified. I want to do a 150cc gy6 swap but with frame extensions in the middle and custom weld in mounts to keep the tire under the stock fender etc and look like a longer stock ruckus, and i definitely dont want to lower it at all, part of its fun is its ground clearance amd ill already be losing enough breakover angle
Ok so as a darksider I gotta throw some input in here. Fotnine I love your channel and you are amazing for great info. But I recommend 2 things for you to do before finalizing this. 1) use a heavier bike. VTXs, Goldwings, Road Kings, Street Glides, Indian Chiefs, etc.... And 2) use a proper car tire. You need full symmetrical or directional treading. It makes a huge difference with handling. That asymmetrical that you were using probably felt better turning to the left and horrible turning right. But more importantly, traveling straight will cause your bike to rut drift. Your rear tire will cause your bike to push your front instead of being pulled by the front.
Totally wrong bike to do this on. I wouldn’t recommend a car tire on a rice rocket or Ducati, but a 1000 pounds of Goldwing, 2 up and pulling a trailer makes all the sense in the world!
Anytime I've heard of a car tire on a bike it's on a Cruiser. Straight line down the highway, no problem. More than likely they don't plan on cornering often. Strictly straight line use.
Towing any trailer behind any motorcycle makes no sense, just like this ridiculousness. If you need a trailer behind your bike, you're carrying too much stuff!
Ducati… no! Yamaha FJR1300… ABSOLUTELY; best damn motorcycle tire I ever put on back there: BF Goodrich g-Force comp-2 AS steel belted radial. Outlasts a premium MC tire 6 to 1, and grips even better in the fun stuff. 😁
Thank you for doing this and spelling out the details so clearly! This needed to be done! Handling is the most important (and well-designed) part of my Honda GL1800, and I wouldn't sacrifice it (by using wrong-shape tires) for anything. Smooth transition across the center point when going back and forth (and I ride in the mountains a lot) is critical to the DRIVER controlling the MOTORCYCLE and not the other way around.
I agree! My Wing will always have the prescribed overpriced tire on it as that is what the little gnomes in the design studio engineered the bike to use. Cars are a totally different matter. My old Firebird had huge rears and standard fronts, my Jeeps all had knobby rollers, my Miatas all had racing tires, etc... but at no time was I counting on just one tire to keep me planted firmly to the asphalt! I even saw a car with the donut spares at all 4 corners! (Technically he could drive up to 50 mph for 60 miles... ) but that thin line my tires make is all I have to keep me upright... So Dunlop or Michelin will be getting my cash as needed.
Do you see any motorcycles anywhere, that want a square section tire?...Moto-Gp bikes would use square section tires if it was a massive improvement. On a motorcycle tire,when its worn out? Its flat in the middle.= square section.
Heavier tyre makes for higher centripetal forces. That means more rider input to bank the bike. It also puts more force on the shock's reaction, more likely to botttom-out the shock on compression and rebound. It also takes up more engine power to accelerate meaning slower response times to throttle input.
@Mr Murders lots of modern performance-oriented road tyres (actually meant for bikes that is) have multi-compound construction, as you described, to reduce the wear when doing highway/commute riding and still enjoying good grip levels in the twisties. Some even have a 3rd intermediate compound in between to soften the transition and provide a more homogeneous wear :)
First World problem. I lived in the Third World for several years in the late 90's. In addition to the matter of expense, there was the matter of availability of motorcycle tires. It was not uncommon to mount a car tire on a motorcycle. In fact, I knew several car tire shops that commonly did it and knew which tires would work best. These are more like tin roof dirt floor shacks than shops, so don't picture a suburban tire shop in the US. We really didn't deal with highway speeds either, a very different context than riding in the US. I had a car tire on my bikes a couple of times. This matter wasn't just limited to tires. Voltage regulators, switches, relays, and even alternators for cars were fitted to motorcycles to keep them on the road. I saw an XS650 with an AC Delco alternator driven by a belt off the left side of the crank. When having to replace a sealed beam headlight was when I realized the difference between a car and motorcycle lamp. I had to use a car lamp and had to adjust for the off center beam it threw out. We would commonly use automotive mufflers as motorcycle mufflers tended to rust out really fast. They actually had a "safety inspection". You would ride up to a little booth, pay in advance, then the guy in the booth would take your bike out for a ride, really a joy ride. On more than one occasion, when he liked the bike, you might not get it back until the next day. If you had a new bike or a nice bike you avoided "safety inspection". Most of us didn't have valid license plates or any documentation anyway. In fact, if your car or bike was stolen in the US/Europe/Asia/SA, it isn't unlikely that it was shipped there in a container and sold. I knew a rental car company that was running mostly cars stolen from the US. They had no titles there and you could get away with hand writing a bill of sale yourself to get a license plate. Bikes were constantly stolen and most didn't have a key ignition for long. If a cop busted you for any traffic violation and you didn't have documentation for the bike you just paid him off anyway. It was how the economy worked, it was how cops made their money. They left the poor guys on ragged bikes alone mostly, if your bike was nicer they would find a reason to pull you over to get a payoff.

Adventure rider move.
Terrible idea? It's saved me bundles and given me thousands of hours of good times. Before I went darkside , tires were an ongoing issue. Not anymore.
Again, car tires existed before motorcycle tires, and motorcycle tires came long after motorcycles. Unless you count the bicycle tires that OG motorcycles road around on as "motorcycle tires".
Please, stop being childish about this topic. It's like believing "reefer madness".
Yup, I would have never thought about that option.

I've ridden darkside. I actually rode Darkside for over 5K miles, before lowsiding it in a curve one day. The handling characteristics are truly shit. That car tire will follow the contour of the road. I was riding interstate 200 miles a day, which is one reason I made it so many miles before crashing. Let me tell you, Darkside on the interstate is like sitting on the sofa, it is so smooth. It wants to stand straight up, allowing me to cross the entire Dauphin Island bridge with out touching the handlebars. On the other hand, i ran through some tiny pebbles in a curve one evening too fast. I had to "force" the bike to lean far enough, so far, in fact that the asphalt contacted my rear saddlebag, taking the weight off the wheel. I corrected by steering back toward the center of the road, that's when the tire got in its happy spot , back on the tread, going into the old "death wobble". During the extreme leaning, the engine guard had contacted the asphalt and wrapped around my right ankle, rendering me helpless as far as using the rear brake pedal. Long story short, i now can't kick the bike away from me, I'm attached by the ankle, lowsiding on the left side of the road between two street sign posts. That's when bike and I both went over the embankment, still attached to the 700lb beast. She flipped mid-air and flung me off. Came out out of that with three broken toes, and the toe burned off my right boot, oh, and a totaled bike. No more Darkside for me.
"Don't knock it till you crashed on it" - guys, I found someone who crashed on it, can we knock it now?
Engine guard and saddlebag touched the asphalt while leaning and still tire fault??
@@adilsonlegalyt9647 he said the tire caused wobble. I’m not an engineer but i kno tire geometry is very important on a bike. When you lean the bike on a square tire i imagine a sudden jump from the center line of the tire a couple inches over to the edge of the tire where the rounded front theres a smooth transition. Aside from the tendency for the bike to stay upright on the flat, when its at a 45 there is gonna be a mis alignment of the two contact patches by an inch or two i would think. The relation of the contact patches to lean angle, rake and trail are pretty delicate in my experience and designed so you can corner no handed if you want. A low rear changes it enough so that you have to counter steer just to keep the bike leaning in a corner.
So i cant imagine how terrible a square tire would handle. I worked at a bike and had a customer that rides all over the us on a gold wing and I think he said he put 30,000 and counting on a car tire i just cant imagine enjoying country roads like that. In saying that i cant remember what tire he used but from wat i can remember it was pretty specific

When you find yourself going faster than you should be in a long, sweeping corner, MC tires seem like a real bargain.
The non-motorcycle specific tire will hold just fine when you find yourself going faster than you should in a long, sweeping corner, with better traction should there be dust, dirt, and/or water on the road surface.

Car tires on the rear work far better in wet conditions than motorcycle tires and have a better traction patch
@@OldSchoolParatrooper If riding in a straight line but once you wish to corner then it would become more dangerous. If the rear square tyre forces you to keep applying steering input to the front as you lean over then that is taking away from what little front grip you have. This is same as braking and cornering at same time i.e. the braking force removes some of the grip available for cornering hence you are more likely to lose a front trail braking into a corner or too deep etc
Marc Fox, it is clear that you have no experiance.
5:36 "Car tyre fits a motorcycle like I fit a bikini. Humps and curves in the wrong places" 😂😂😂
Bad Idea...here's why...Front tire contact patch, about 1 1/4" wide. Rear contact patch, about 7", and that is where all the stability issues begin. If the LEFT side of that wide tire rolls over a high spot in the pavement, the bike tilts RIGHT!! and vice versa. If riding a "truck lane" and you get into one of those two valleys in the pavement that heavy trucks create, the bike constantly weaves back and forth, depending on which side of that wide tire makes contact with the slope of the valley. I always had to ride the center of the lane to avoid that weird greasy feeling. After about 3 months I drop kicked that tire into my garbage bin....never again!!!

@@stupollock6851 car tires on sidecar motorcycles is nothing unusual. even in the front. I don't know where you're from but here in Europe motorcycle tires on sidecar-conversions are relatively unusual.
jomcjay yes I have seen them when I was on the Isle Of Man. I’m not particularly fond of the look but on back maybe not as noticeable. I’m from Northern Ontario Canada and planning trip on ice road in far north. Just think bigger back tire let you haul more without sinking in snow. Plus added traction. Plus supreme wear and saving. I don’t know why they can’t make bike tires last longer.
@@stupollock6851 they can make bike tyres last longer, and they do. Back in the day I was lucky to get 3000 km from a Pirelli Phantom on a 60 hp bike before the cords showed. Now I get 18 000 km on a 75 hp bike and I change them when they're still legal.
More than that may one day be possible, but right now it's a trade off between handling+grip vs life. There are some very flat, car like tyres that will get you 30 000 km, but they handle like shit, slide all over the place and are really hard to change. So people don't buy them. So they sell in small numbers. So they're expensive.
A few years back I bought a GoldWing that had a car tire on the back. Everything you said was valid. There was another issue that you didn't really cover. The hard rubber causes way less traction even in a straight line. The Wing would light up the tire every time I would accelerate, even with my wife on the back. It followed this up with locking up whenever the brake was applied. So, in addition to not cornering or going straight, it also couldn't accelerate or brake. But at least it would last the rest of my life. Just like a parachute that doesn't open.
The traction issue would be very dependant on the particular tire used, there are soft road car tires out there, there are also long lasting "eco" tires that don't grip for shit, so is the case for motorcycle tires really- many people would be better off with a soft car tire for commuting rather than a hard moto one.

I use drag radials on the back of my V twin. Waaay more cornering traction than the michelin cruiser tire I had on it. I couldn't pull a wheelie before on the bike tire either. It just spun. Now it picks the front end up. You do have to countersteer in the corner, but the bead conforms to the motorcycle wheel much better than you're hearing here. There are no metal bands on the far inside lip of a car tire. That edge easily conforms to the inner bead of the bike wheel.

Yes this kid is a genius
My 2006 Rocket III Classic was a great riding & handling bike with a 225/50R-16 Dunlop Direzza DZ101. Perfect match in all dimensions to the stock Metzler 240/50-16. The sidewall had the same rigidity, identical overall height and width, and it was a sticky performance tire. The tread was a sporty symmetrical & directional pattern with a rounded edge. I ran at about 25psi which resulted in smooth, stable, composed handling and MASSIVE traction advantage over the MT. The bead did not look any different than the Metzler either but I was not using a run-flat. I installed and balanced it myself. Trust me, the size & weight of that rim with brake rotor far exceeded any worries of unsprung weight. And yet, the Dunlop was fairly light as well. I had no vibes or gyroscopic tendencies at any speed. My bike would top out about 135mph - limited by the windshield, floorboards, and bags (and my fat butt). I scraped the boards frequently (thankfully they articulated). If blindfolded, one would only know it was a CT at walking speeds. Above that it was almost unnoticeable. Yes, a bit more counter steer was needed to initiate a lean but by the end of the first day riding you did it subconsciously. Grooved road surfaces didn't affect it much but I think that depends on the tread, pressure, and width mounted on each bike. For my bike/tire combo, it was well behaved, confidence inspiring, and FUN to drop clutch and peel out. No more applying throttle timidly while turning for fear of losing the rear. Nope. pour it on and leave a beautiful black arc behind.
But before I have rotten vegetables heaved my way, yes, there are some drawbacks and you need to gauge your abilities. If you have even the slightest doubt, then by all means don't do it. Those of us who darkside don't just throw any POS tire on there.
#1 - Darkside is not for all bikes. The GS is probably not the ideal candidate being so tall and narrow. Best left to heavy, lower, tire grinders like Power cruisers & touring bikes.
#2 - Narrow rim & wide tire are not a good combination. DS works better on a wide rimmed bike. In this test a narrower tire (if even possible with the given wheel) would have produced better results.
#3 - Tire pressure looked high and gave the impression the handling looked edgy. Inflation is key to good tread/sidewall compliance.
Regardless, I thoroughly enjoyed the video and would say almost everything he said was correct.

I have to disagree with the "higher mileage" point. Having been turning wrenches professionally on bikes for 15+ years, I have changed thousands of tires in my career. Many were utterly destroyed car tires. The tread wasnt hurt hardly at all. Its the sidewall that takes the hit. When you put big fat bikes on a 2 square inch contact patch while cornering, rubber flexes. Being that the sidewalls are drastically thinner, they flex first. This will generate excessive localized heat and wear and will eventually appear as if something was jammed into the side of the tire and rubbed a groove into it for a few hundred miles. Ive physically seen the sidewalls fail and cause the bike to go down, which totals the bike. And get this, these tires only had a few thousand miles on them.
Maybe its different in flat states without a single turn for hundreds of miles, but out here in east TN where the road maps look like a plate of spaghetti, darkside is a big hell no!
Couldn’t have said it better my self .
Every time a post like yours comes out, or like one I mention where a dude crashed twice on car tires, due to blowouts, I'm told to "prove it". It's funny how one side is believed, without comment, while another is disputed. Great comment.
@Wroger Wroger Another good point. Ill add that motorcycle tires work best and have the most traction when they are warm. They become more malleable and adhere to the road better compared to when cold. Car tires are designed to resist all heat buildup possible so they last longer and will NEVER benefit from the effects of a warm tire and will not have the same amount of traction as a real motorcycle tire.
There are sometimes blowouts with car tires, because run flat tires are run way too long without any air. They are so dang dependable that some folks think they can ignore routine PSI checks. However, a low tire sidewalls are MORE vulnerable upon the thinner motorcycle tire, and I've been guilty of ignoring them when I was young.
Another neglect caused by car tires is the required maintenance on shaft drive bikes. The car tires last three or four times as long, so gears are neglected until they run dry and self destruct.
A flat state, and commuting 80 miles each work day, was exactly why I was considering them, but no car tire would fit the back of the Vulcan I had. I would have done it in a heartbeat to avoid changing out rear tires so much. The way I see it, I wouldn't do it for two bikes, but for a dedicated commuter or cross-country bike, sure.
I've darksided a GL for the life a tire, mostly through a very rainy winter in Portland, OR... it was good in snow, it was good in the rain, and it was good for towing a trailer. The tire didn't last much longer than an regular motorcycle tire, in a large part as I spend a lot of time on the sidewall. (I used to own and now occasionally teach for the Northwest Motorcycle School, where we taught a motor officer course to the general public, and much of our riding was full lock, full lean and below walking speed.) I simply wore the shoulders of the tire out, while the center tread was fine. I'm not teaching regularly now, and living in New Mexico, with it's mostly straight roads, I spend far less time on the tire's shoulder. I was looking into another darkside tire, when I noticed the weight difference. A car tire for the GL weighs between 9 and 11 Kg. (20-25lbs), while the motorcycle tires weigh around 3 Kg (according to manufacturers). That terminated my search, the durability might be great, but the added, un-sprung weight kills suspension response, and may have been a good portion of why handling "sucks." Yes, the bike understeers with the car tire, but, as noted in the video, it takes about 10 minutes to get used to keeping pressure on the bar while cornering. However, the tire's following of rough roads is severely compromised, particularly when leaned over. Just one more element to consider.
That was my experience. Flat roads ok uneven roads were really bad. Grooved asphalt was scary. Went back to motorcycle tire.

Now do whatever you like.
This is one of the best darkside videos I have seen. It’s not arguing for or against but simply putting the information out there. We darksiders will never say that the handling is better than a motorcycle tire and we would put them on our track bikes just that for the riding we do they are perfectly adequate.

Pneumatic tires, such as those on a motorcycle, Do NOT behave as classical dry friction theory would suggest. Rubber generates friction in three major ways: a) Adhesion, b) Mechanical keying, and c) Wear
Furthermore pneumatic tires are sensitive to load, as they are loaded up the coefficient of friction decreases.
Reference:
The Racing & High performance tire, Paul Haney, 2003
Or wiki, if you guys don’t want to buy the book above.
en.wikipedia.org/wiki/Tire_load_sensitivity
Now I read that wiki page, and I have my B.ME working on my M.ME I know the other kinda forces.
All this says is that it's not a component vector of dry friction but instead Coulomb's friction.
This just means motorcycle tires get more grip in a turn since their sliding factor is more.
Right the dry equation is simplified but is good enough. You do have only so much grip to go around, and the advantages of motorcycle tires is that you don't fight the tire in a turn, where as a car tire you do. You don't get enough grip back out of Coulomb's friction to make up that deficiency.
Sure for F1 it's a serious concern and that's why we slightly camber those tires.

This shit is interesting and i kinda wish i did my masters in this instead
The tires being pneumatic vs solid has nothing to do with it. It is because a soft material (like rubber) on an abrasive surface (like pavement) has a coefficient of of friction that is itself a function of normal force. The equation ends up looking like F=z*N^s where 's' is usually around 0.95, but must be measured experimentally.
I absolutely love seeing a TH-cam comment debate with citations in place of curses, I'm glad to see fortnine cultivates a very friendly, non-toxic community
Besides the coefficient of friction of the rubber, there is the coefficient of friction of the pavement. In effect it is a combined coefficient of friction - of that tire rubber on that particular pavement. And oh yes, pavement friction varies depending on the aggregates it is made of and any polishing that takes place over time.

I put a Falken tire designed for the tuner market on my Honda VTX1800 and loved it. It was different from your choice in a couple areas. It has symmetrical tread, reinforced sidewalls, and rounded tread at the edges for better cornering. It did have better life and lower cost as you mention and better load capacity. What you didn’t mention was the better water handling capacity and the much better puncture resistance. I tested the tire with no air in it and it functioned for low speeds. Finally, when I had the second car tire put on the dealership called me and asked permission to cut the first car tire off the rim because it was so tightly fixed to the rim. The downside was low speed turning. You can definitely feel the bike as it transitions from the flat to side tread. I wouldn’t think of it on a sport bike but for a cruiser it was great. One last thing, My wife said the ride on the pillion was much smoother with the car tire. P.S. My original tire was tubeless and the rim geometry was not like what you show in the video.
A friend of mine also fitted his Kawasaki Vulcan with a car tire on the back, and he said it was the best thing ever.
I rode in VTX group and many went dark side.
Even if the wet traction is "good"... I would think taking curves in wet weather (once you're off the flat part of the tread) would be really scary
@@julianbrelsford there are pictures of the contact patch of a car tire vs a motorcycle tire and the car tire actually has move contact area in a turn than a typical motorcycle tire. That is true for the ‘tuner’ marketed car tires that have geometry designed for drifting and high speed cornering. The contact area on a motorcycle tire is actually very small, but consistent no matter the lean amount. As I said in my original post, I would not recommend a car tire on a crotch rocket but for a 700+ pound dry weight cruiser it wasn’t a problem. Also, I added floor boards to both riding positions so the cornering angle was substantially reduced anyway. Even if the traction was equal, I was still comforted by the thick side walls and tread on the tuner tire that allowed the bike to operate with no air in the tire. Also, you can plug a car tire to get you home and that is highly discouraged with the light weight motorcycle tires with very thin tread area.
Just to clarify, contact patch has nothing at all to do with grip, as per Ryan's explanation. It is purely a function of how sticky the rubber is and how much force is being applied to it. The 'tuner' tire example likely has more working tread towards the edge of the tire, making it less sketchy for this use-case, but still sketchy considering how the car tire will always want to 'upright' itself after a few degrees of lean.

Great info on the video! One thing I would recommend when inflating a tire on a rim it was not designed for is to put it in a cage or wrap a chain or ratchet strap through the rim and around the tire to contain it should the worst happen. If the tire blows off the rim when seating the bead, it could seriously kill you!😝
What do you think happens when a tire “blows off the bead?” Do you think it’s gonna fly across the building? Really? Do you? Think about what your saying. That tire was just put onto that rim, used some serious force to get it on too. Multiple steps, do you think the air pressure energy is Going to do all those steps, in an instant?
@@shelbystrong3663
Yes Shelby it has happened! My cousin got his jaw broken when a front tractor tire he was inflating blew the rim into his face. NOT a pretty sight.
@@unclehornet5122 I don't think a tractor tire is comparable to fitting a small car tire onto a large motorbike rim.
Having been an auto mechanic back when the 16.5" truck tire was a thing, the darksiders lost me at "incompatible bead".. but as you said so well, let it go!
I have been using Dunlop 185/65/16 car tire since 2006 on my VTX 1800 it took a little getting used too but you run tire pressure depending on the bikes weight I ran 34 PSI and it stuck like glue even in rain and tripled my tire mileage to 40,000 km

The Boss Hoss came with a car tire. Factory mounted. If I remember correctly that is. The handling as legend has it confirms your experiment on car tires on motorcycles. Well done sir, and very well explained what to expect and why.

Darksiders chiming in. When the 1800 Wings came out, tire life of less than 10k was common, even 7k wasn't unheard of. Early on there were issues with tires delaminating due to underinflation and overloading. I was going through 2 rears and 1 front every year.
I spent several days investigating everything I could find about darksiding. After all that and personal experience, this is what I concluded. The following link is my video with a camera under the bike. th-cam.com/video/qoNDo7o1d6Q/w-d-xo.html
Not every tire works. Some designs work better than others. In my opinion, run flat tires are a must. The sidewall wraps around the rim and locks it in so we'll, that installation and removal is a bear. The rim profile mismatch is a fact, but the runflat sidewall locks onto the rim so hard, that I have to plan as much as 2 hours to change the tire when it's already off the bike.
Handling is greatly effected by tire pressure. To high, and the tire doesn't flex enough. I run 25 psi cold and 30 two up, 34 fully loaded pulling a camper.
Handling is different, but it's no problem to throw the bike around in the curves. The front tire effects the initial counter steering into a lean. When initiating a turn, I feel the front take the lead setting up for the banking turn. Once banked over, the bike will maintain it's lean angle. Even using cruise control in a curve, I can remove my hands from the bars and it maintains the bank.
Off road traction is fantastic. I love riding dirt roads and trails. My current tire is a snow tire. I managed to drop my rear tire into a hole at a campground that the belly pan was on the ground while I had a trailer attached. The back tire climbed right out of the hole.
I tested the run flat capability by removing the valve stem core and riding with zero air pressure. Normal riding was unaffected, while banking over just made the bike feel heavy.
I was rear ended while having the car tire on. Progressive didn't care and even payed for a replacement car tire.
Is darksiding for everybody, no. When properly installed and balanced ( I balance to + or - 1 gram ), using a tire pressure monitor ( you could get a flat and not know it ) and common sense, Darksiding works great. It's not something to just jump into.
I respect the people who make TH-cam videos explaining the science of why it's not advisable. I understand the science, but I know how it works for me. As long as I'm riding my GL1800, it will never see a motorcycle tire on the back.
Anytime we make modifications to our motorcycles, we have to accept that it's our responsibility for anything that might happen. I choose to run a car tire, and it's on me if anything ever went wrong.
Well written. In this case he installed a car tire on the wrong type of bike, rode it in the wrong kind of conditions and claimed it was wrong to do. I know of many people who have run dark side on their bikes for many years with no problems. I'm not sure why he is against it except, perhaps, he sells bike tires?
AGREED I HAVE HAD GOOD RESULTS WITH CAR TIRES AND I NOW HAVE THEM ON 3 ......BIKES EVEN A BIG SCOOTER.
@@davemeise2192
Why are you so buthurt and emotional?
Wrong bike? Wrong conditions? Are you high? If you want to prove or disprove something you need to take it to the limit, that is the point of testing something, to put it in adverse conditions.
And if anything he made unbiased and reasonable argument, he made a solid case FOR going to the dark side if anything.
Ok
@@davemeise2192 He didn't say it is wrong to do so.
He said you're lacking the built in saftety of the bumps locking the tire in, and because of this the tire COULD unseat itself.
And then proceeded to tell you it's your own risk, without giving numbers as to how often this happens.
And in doing so, he is 100% right. It does lack the safety features, and it COULD happen. You might go a 100 tires without it happening, and good for you.
But he has to say this in order to make sure you understand how it works, and that it's your own risk.
If he tells everybody to do it without fear and a tire does go wrong, he gets the blame. Simple.
Back in the mid 2000’s I did this on my 1800 Goldwing. I didn’t know about the bead differences. That aside the tire did work. After the scary first ride it was pretty normal except for the part about tracking on grooves in the road surface. Annoying at first but you get use to it. From what I remember the tire didn’t last that much longer than a good MC tire. The car tires wore out at the edges first. Both of them. I ended up going Back to MC tires after that. It just rides a lot better. Going back to MC tires felt like adding power steering.
not true for the newer run flats . but in the north we go straight a lot . lack of curves
tire pressure is the key. and not what the sidewall says either
I ran a GL1200 Goldwing with a side car and a car rear tire mounted perfectly. It ran great and I highly recommend it for sidecar applications. I tried it with the sidecar taken off the bike. On the highway I got in an absolutely terrifying tank slapper that is singularly the most frightening riding event of my 50 years of riding. I don't know how I did it (thank you guardian angels!) but I controlled it from a side to side, to the stops, tank slapper at 80mph (I know, I was pushing my luck). I sat on the grass at the side of the road for half an hour to get the adrenaline and heart rate down. I thankfully learned my lesson without loosing my life.
Maybe car tire applications on moto are for heavy weight moto, also tubeless tire is the way to stop Tire re-T900-coming-back to original form and fighting itself
I ran a car tire on a 650 Burgman for a few years without problems. Handling was as good as the OEM tire once I got used to the slightly different feel. Also of note was the much smoother ride, especially when the air pressure was around 32-34psi. More air and the bike rode more on the edge, making the bike feel squirrelly. Darksiding isn't for everyone.
Saw this on a goldwing just the other day.... needless to say your weight on the rear tire was seriously underestimated once I saw the couple whom it was come out of the restaurant. Great vid per usual!
I did this on a 1st gen Yamaha Vmax. It makes the deathtrap of a machine even more dangerous, but still awesome to ride. The flex of the huge sidewall added into the flex of the frame and suspension takes a lot of skill to maneuver. It also adds a "speed limiter" of sorts. When you get around 105mph the whole bike starts swaying side to side unless you back down on the throttle.
about the only time it'd worth it is for drag bikes.
Thank You Sir for actually trying this out and showing how it can be done. And then giving us an honest, in depth, exactly right on presentation of how it works and the advantages and disadvantages of running a car tire. Your explanation about having constantly counter-steer thru a corner was very insightful!! The way a motorcycle handles does change for sure, but you get used to it.
Certainly you wouldn't put a car tire on a canyon carving sport bike!! For a heavy touring motorcycle, the fact that a car tire lasts so much longer is a huge advantage. It certainly saves time and money!! Why spend a $150+ to have a rear tire replaced every 10,000 miles or so (usually less!!) when I can safely use a less expensive tire that lasts 3 times longer?? Also, having to replace a tire when on a long trip is not fun. For me, every rear motorcycle tire I have replaced is worn out in the middle and very little wear on the edges. So using a car tire is so much more convenient.
This has been done for a long time as mentioned in the video. An older friend of mine said they used to lace up a 15" rim on their choppers so they could run a Volkswagen tire on the back. Using car tire works!! And for me there's no downside. And the fact is, people do this all the time. Thanks!
Yeah, seems like the car tire makes sense if you just commute or do lots highway miles. I know guys who replace their rear tire every year. Not to mention the cost of a puncture. That said, I'd probably try to find an inner tube that fits if I were using a car tire.
Tatwood, thats where runflats are great. And i mean do you tube your tubeless mc tires?
Thanks, Ryan. Very well done, as usual! I have had a Semperit M&S tire on the back of a Burgman 650 scooter now for 3 years. Works fine, EXCEPT: longitudinal seams in the pavement are downright scary! Leaned over traction is not a problem, since the giant scooter does not lean over very far anyway; parts drag right away. The M&S tire actually gives some traction; the stock tire gets stuck on wet grass. Still not sure about tire pressure; anywhere from 25 to 40 seems to work just fine. Please note that I am a dirt rider, and might not be noticing some of the nuances of pavement handling. Thanks again!
He's a real motorcycle guy, the flip phone proved it😂😂
@Hippity Hoppity Then buy a used phone from an independent seller
I mean, I work in tech yet I have a OnePlus 6 (not a bad phone when it came out but close to outdated by today's standards). Flip phone guys have a point. They never need software updates and the battery is almost always replaceable. If the battery in my phone goes bad it's likely going to cost more than the value of the phone to replace with an OEM part. This is by design.

@@marc-andreservant201 just fyi if you are okay with DIY look into ifix it. I replaced the battery for my 6t at one point for 50 bucks. If I ever need to replace it again it would be about 30 dollars because I don't need the tools anymore.
I use a Goodyear triple tread on the back of my Yamaha Stratoliner. I have used it for 4 seasons now. I did notice handling differences when doing heavy cornering. On gravel roads or uneven pavement you have to keep your wits about you. The tire does want to control the bike and get back to being straight up in those circumstances. Over all I am happy with the car tire and have 20000 km on it. I check the pressure regularly as we all should and ride. My advice for anyone thinking of going to the Darkside is do your research on type and quality of tire. I would not use it on anything but a big cruiser or tour bike. Sport, adventure, and other style of bikes I believe should stick to motorcycle tires. Great video.
I'm wondering what would happen, if you took a sidecar set up such as a Ural, and made it a darkside bike? The main problem with sidecars are that stability is a constant battle. But with your tires doing some of that work for you, would it make things easier?
For sidecar motorcycles definitely you can use it without an issue, you don't need to balance it
The can am spyderrs have auto style tires
They also have three wheels
I have a 85 Gold Wing 1200GL & Dark sided it with a Nexen 165/80/15
Cornering is no problem and now I have better braking, grip, water displacement
and far better with a passenger + trailer. It also has an actual load rating...I'm staying on The Dark Side !.
1:39 the use of cable ties are ingenious
I've been installling my motorcycle tires this way for about 10 years now. With most of them, I don't even need tire levers anymore. The zip ties are so slick after you get the beads to touch, you can stand on the tire and it just scoots onto the rim.
Been a Darkside Wing rider for two years and will never go back, the bike is just to heavy for motorcycle tires and cupping occurs, over 45 000km and still fine for 125$. Don't think i would use it on any other of my bikes though, can't feel much of a difference on the wing, your video quality is amazing as always
What kind of bike do you put it on?
Can advise will it be ok for 650 Kawasaki Versys?
Goldwing
Baeng's Lobster (Wan Jtk) On my Goldwing, i would not advise trying it on a smaller nimble bike as it will take away from its performance, the Goldwing is over a 1000 lbs loaded and the rear wheel is better suited for the switch, i don't ride it like a sport bike like some Goldwing riders are know to do, so i can’t feel much of a difference at all
@@MrRamman04 thanks for the reply
@@wanjtk if you want any fun riding don't ever do that. Modern motorcycle tyres are mostly all good, but I had a Honda cb500, limited to older models. Came with way to old not so good ones. Definitely felt a giant difference when getting better ones.
I'm not a biker. I was a motorcycle commuter. At 8000 miles it was time for my third rear tire. I put my first car tire on my kawa 900 lt. 25,000 later I bought another. At 50,000 miles the demands of having to pick up a grandchild at daycare for thr next 6 years meant I couldn't ride as much. 5 years and aound 55,000 miles later I worried more about the car tire rotting then anything else and it has mc tire on again. I did my 1000/1500 IBA ride on it, up pikes peak with it, oshkosh airshow with it rode as closer to the big mac bridge as weather and time would allow from parking lot practice to the occasional run up to 115 mph (Kansas tail wind and big shield helped a bunch fit the little bike). Mc tire feel better? Maybe. But 70 dollars for 3 years instead if 600 for 1,I didn't feel that much difference. Liability? It's dot rated, never caused a problem.
Not for everyone? Ya. A solution for a problem? Yup.

As if this has ever happened......Please someone post a link where this has happened...
@@justmyself1000 I've been doing on-and-off research on darksiding for twelve years and have read nearly a thousand NHTSA motorcycle crash reports, and have never found ONE where the primary- or even suspected- cause of the crash was a bead failure on a darkside (DS) tire. Plenty of drunk/impaired riding, lots of cars turning left in front of bikes, many excessive speeds, failures to negotiate turns, and even some tire failures (ALL of them motorcycle tires and often due to overloading or running underinflated), but nothing that would suggest DS is an unsafe practice. I have challenged the naysayers to provide ONE verifiable case of a crash or refusal of insurance claim due to DS, and have had ZERO takers. I've been riding the mountains of northern Wyoming for three years now on a V Star 1300 with a BF Goodrich, and it is a fantastic combination for comfort, durability, and safety.
Got to admit, when I first saw the slow-mo of him slaloming with the car tyre my first though was 'Oh, so this is how dies...' Genuinely surprised that actually worked in those conditions and for that distance.
Still, I never cheap out on tyres unless I have to. Best advice I got was from an old instructor who said think of the physics - everything you do on the bike is theory; there are only two little patches where it becomes reality.
Amazed you did all those riding tests without wearing heavier crash gear. I have never ridden a dark sided bike that I felt it was stable in any way.
I've been darksiding my Goldwing for a couple years now. Since my ride is my primary mode of transport, I'm putting 30k miles a year on it. Motorcycle tires--$350 Goldwing tires--get expensive at that rate. It takes a few minutes of getting used to, but like he said, you don't notice after that. Never had any problems. In fact, where my motorcycle tires would sometimes spin in the wet under the fantastic torque load the Wing's car engine puts out, the car tires never do. I'm never going back.
It seems he chose the widest tire he could fit which which meant an extremely low profile sidewall, which affected his handling far more than necessary. I run a Sunfull SF-05 185/75R16 truck tire on my Gl1500, barely wider than stock, and I can't really tell the difference between it and the stock tire except for the weight of my wallet. A goldwing tire lightens my wallet to the tune of $200 or so, and this tire that will last 3 times as long for only $59.95 and free shipping off Fleabay! It does scrub my fender a little on bumps if I don't keep the shocks aired up to about 30lbs. The Spontaneous uninstallation.is a great line, but 4wheelers will deflate big tires down to 5psi for crawling over rocks and rarely have one deflate. Another plus that he didn't mention is that the light weight of a motorcycle will rarely push an object through the steel belt on the car tire. I went darkside on a Shadow 1100 because of picking up a nail at least once a month at the construction entrance at my job. Put 20k after switching and never had a flat again. I still picked up nails, but would hear them clicking and stop and pull them out. This bike rode much better, especially 2 up and was only a little loose feeling on gravel roads. Tire still had well over half it's tread left at 20k when I sold the bike.

Couple of extra added observations from my time trying the dark side on a GL1800. My car-tire did not last as long as the motorcycle tires I usually ride on. It provided more traction while leaned over than a motorcycle tire. I could give it full-throttle while leaned-over without losing traction. Full-throttle while leaned over with a motorcycle tire will cause my GL1800 rear-tire to lose traction and break lose. That said, the stand-up tendency was enough for me to not continue the practice.

One thing you're missing is that after 600 or so miles, the car tire "corners" "break in" to their new use, and the corners give while you take the curves. This gets better as the tire adjusts to it's use. Trust me. Darkside on my '98 Valkyrie. I was convinced by a madman from Dakota, in whose sagacity I believe. I'll probably never go back to a $400 rear motorcycle tire -- especially after the horrible experience of my last motorcycle rear, the Limey Venom, that was the worst tire I ever rode.

I'm on my third car tire on the rear of my 07 Goldwing. All 3 have been runflats. I have a total of 90,000 km's with car tires. My 3rd which is a Bridgestone has 20,000 km's on it and is good for at least another 20,000. Why? I can afford what ever I want. My observations are that the car tire has a far higher load rating, it's hugely superior in the wet,it lasts far longer,no one and I mean one one that I have heard of has had a "blowout"., the handling is suberb, braking is better, and lastly my wife says the ride is "plusher" Many thousands of riders have put millions of km's on bikes with car tires. I'll never go back to a MC tire. There is a web site called darkside info that lists the bikes and the recommended size of car tire. For my wing I use a 195/55/R16. Some guys will use the 60 series and or go up to a 205 width. I know riders who have used car tires on V stroms and FJR 1300,s. They too will not go back to MC tires.
David Giles well as mentioned in the video you have to decide. For me it doesnt fit my riding.
i plan to one day get a goldwing and small trailer, either rv or just storage type. with two ppl plus a trailer it makes perfect sense to use a car tire on the back wheel. i just dont feel like a moto tire will handle that load for very many miles. no a car tire is not something id put on any sport bike. i just think of a car tire on that kind of bike to NOT be of much assistance to the performance of a sport bike. but a goldwing was not meant to out perform a sport bike. its was meant for a comfortable long heavy haul which is perfect for a car tire. plus even though they dont lean like a two wheeled bike, trikes use car tires on the back as well AND even the insurance companies have no issues with "the dark side" so long as its (here in the US) a tire approved by the D.O.T.
like yourself, ive yet to see ppl who've tried the dark side to come away from it swearing up and down that it was the most dangerous thing they ever did. never seen statistics to prove so either. if there were, the insurance companies would forbid it in their policies and use it as an excuse to avoid paying out on claims.
Mental illness category, but OK.
@@rebel_ltz I've noticed that bmw cars handle and ride much better when they don't have super stiff, heavy run flats. They are factory installed on all none sport models. Also noteworthy, is that no sport models use run flats because the people that drive them usually don't have their head 5 miles up their posterior, like your average bmw suv driver. So I'd call run flats on a goldwing insane even if the gold wing has 2000lbs on the rear wheel.
Good post, David Giles! Same experience with me but on 5 different cruisers/touring bikes! I challenge anyone to find an accident or mishap caused by a darkside tire! WAY better traction in wet and braking! MORE precise in high speed curves. One needs to know how to ride and handle a bike. No "buts" or "ifs." I used more skinny car tires and with a more rounded profile than he shows in this video and usually spend around $70.00USD! His melodrama is laughable! One needs to find the right tire pressure as well! I've NEVER heard of a darkside tire coming off the bead!!!! Give us a break and qualify these claims! I wouldn't use that tire with that high pressure on a BMW adventure bike either!!...Get informed...
On a cruiser in Texas- Maybe. On twisty roads in Europe - Nope.
Darkside on my Goldwing, I pull a trailer with it and really like the run flat capability. The alternative is to buy a new rear tire every month if I go back to a motorcycle tire. I have not noticed any change in handling at all. Good video- i would say about 80% accurate.

Ok so as a darksider I gotta throw some input in here. Fotnine I love your channel and you are amazing for great info. But I recommend 2 things for you to do before finalizing this. 1) use a heavier bike. VTXs, Goldwings, Road Kings, Street Glides, Indian Chiefs, etc.... And 2) use a proper car tire. You need full symmetrical or directional treading. It makes a huge difference with handling. That asymmetrical that you were using probably felt better turning to the left and horrible turning right. But more importantly, traveling straight will cause your bike to rut drift. Your rear tire will cause your bike to push your front instead of being pulled by the front.
Congratulations on knowing more than the guys at Michelin, Bridgestone, Pirelli etc.
Totally wrong bike to do this on. I wouldn’t recommend a car tire on a rice rocket or Ducati, but a 1000 pounds of Goldwing, 2 up and pulling a trailer makes all the sense in the world!
Anytime I've heard of a car tire on a bike it's on a Cruiser. Straight line down the highway, no problem. More than likely they don't plan on cornering often. Strictly straight line use.
Towing any trailer behind any motorcycle makes no sense, just like this ridiculousness. If you need a trailer behind your bike, you're carrying too much stuff!
@@1212sman I know a guy that tows his BMW s1000rr to the race track behind his goldwing.
@@thecrazybag that's the most swag money thing I've seen this week.
Ducati… no!
Yamaha FJR1300… ABSOLUTELY; best damn motorcycle tire I ever put on back there: BF Goodrich g-Force comp-2 AS steel belted radial.
Outlasts a premium MC tire 6 to 1, and grips even better in the fun stuff.
😁
Yet another GREAT F9 vid. Kudos.
A large friend of mine runs car tires on his 1800 Goldwing. He says once you get used to the handling it's fine.
"It was such a bad idea I'm glad I thought of it "
To make a video on this project took more time than we think, but he manage to make it simplicity, short n sweet. Bravo dude👍👍👍
@Tabourba Yup, via subscribers n viewers. I did subscribes.
That "let it go" at the end is boss.
I didn't even know this was a point of contention!
Thank you for doing this and spelling out the details so clearly! This needed to be done! Handling is the most important (and well-designed) part of my Honda GL1800, and I wouldn't sacrifice it (by using wrong-shape tires) for anything. Smooth transition across the center point when going back and forth (and I ride in the mountains a lot) is critical to the DRIVER controlling the MOTORCYCLE and not the other way around.
I agree! My Wing will always have the prescribed overpriced tire on it as that is what the little gnomes in the design studio engineered the bike to use. Cars are a totally different matter. My old Firebird had huge rears and standard fronts, my Jeeps all had knobby rollers, my Miatas all had racing tires, etc... but at no time was I counting on just one tire to keep me planted firmly to the asphalt! I even saw a car with the donut spares at all 4 corners! (Technically he could drive up to 50 mph for 60 miles... ) but that thin line my tires make is all I have to keep me upright... So Dunlop or Michelin will be getting my cash as needed.
Nobody:
Car tires on a bike...
The TW200:
“Hey, what about meeee?”
The tw200 runs wider rear tires than my Dodge Durango. Glorious, is it not?
I have actually see this in person on a bunch of goldwings. it looked like a terible Idea then, more so now.
Jake Edgell it’ll go more places too🤣
Got rid of the deadly 240 on my M109R, and run a 205 now ,and it's 200 percent better.
I run an ATV on my TW
a vintage car tyre, like a 3.50 x 17, makes an excellent front tyre on a trike. its square section improves the handling massively
Do you see any motorcycles anywhere, that want a square section tire?...Moto-Gp bikes would use square section tires if it was a massive improvement. On a motorcycle tire,when its worn out? Its flat in the middle.= square section.
@@bradsanders6954 please reread the comment. i'm not talking about motorcycles, i'm talking about trikes.
@@bradsanders6954 THREE wheels dude.
Why can’t tire companies make a mc rear tire that does what “darksiders” want ( a heavy, thick belted, thick treaded tire, made for touring )?
Avon Trike front tire, limited sizes though
enter the michelin macadam, the bakelite tyre of choice.
Heavier tyre makes for higher centripetal forces. That means more rider input to bank the bike. It also puts more force on the shock's reaction, more likely to botttom-out the shock on compression and rebound. It also takes up more engine power to accelerate meaning slower response times to throttle input.
Bad their business i guess
@Mr Murders lots of modern performance-oriented road tyres (actually meant for bikes that is) have multi-compound construction, as you described, to reduce the wear when doing highway/commute riding and still enjoying good grip levels in the twisties. Some even have a 3rd intermediate compound in between to soften the transition and provide a more homogeneous wear :)
First World problem.
I lived in the Third World for several years in the late 90's. In addition to the matter of expense, there was the matter of availability of motorcycle tires. It was not uncommon to mount a car tire on a motorcycle. In fact, I knew several car tire shops that commonly did it and knew which tires would work best. These are more like tin roof dirt floor shacks than shops, so don't picture a suburban tire shop in the US. We really didn't deal with highway speeds either, a very different context than riding in the US. I had a car tire on my bikes a couple of times. This matter wasn't just limited to tires. Voltage regulators, switches, relays, and even alternators for cars were fitted to motorcycles to keep them on the road. I saw an XS650 with an AC Delco alternator driven by a belt off the left side of the crank. When having to replace a sealed beam headlight was when I realized the difference between a car and motorcycle lamp. I had to use a car lamp and had to adjust for the off center beam it threw out. We would commonly use automotive mufflers as motorcycle mufflers tended to rust out really fast. They actually had a "safety inspection". You would ride up to a little booth, pay in advance, then the guy in the booth would take your bike out for a ride, really a joy ride. On more than one occasion, when he liked the bike, you might not get it back until the next day. If you had a new bike or a nice bike you avoided "safety inspection". Most of us didn't have valid license plates or any documentation anyway. In fact, if your car or bike was stolen in the US/Europe/Asia/SA, it isn't unlikely that it was shipped there in a container and sold. I knew a rental car company that was running mostly cars stolen from the US. They had no titles there and you could get away with hand writing a bill of sale yourself to get a license plate. Bikes were constantly stolen and most didn't have a key ignition for long. If a cop busted you for any traffic violation and you didn't have documentation for the bike you just paid him off anyway. It was how the economy worked, it was how cops made their money. They left the poor guys on ragged bikes alone mostly, if your bike was nicer they would find a reason to pull you over to get a payoff.
