Day 639 of asking Donut to bring old B2B back
You'll get more zero effort listicles and like it...
Nah I want more F2F
@@tinncan I ❤️ listicles
I hadn't seen you post in a while. I was worried about you. I thought you gave up.
What about all you need to know??
can we just take a moment to appreciate the real mvp's here? them damn spacers holding this whole video.
spacers just have a bad name fam if applied properly they go forever ... im 3 years on 50mm spacers and not a issue in the world altho my mind hasme check the torque spec every so often its always spot on i just cant help but feel that something gonna mess up but been great sofar and i beat the hell outta the car lol 😂 😂 peace n love bro keep it rad stay safe and build on
You god damn right
@@mastercricket7626 one set of spacers should be fine. But when you have half a dozen of them then it's not gonna be a good time for your suspension lmao
Whistlindiesel has proven what you can do with spacers haha
Well the spacers and the extra leveraged twist on the suspension parts themselves
Hats off to your editors and the spacers on this one!
@@repentandbelieveinJesusChrist1 um, no. Creep.
Really surprised the spacers hold up :)

Remember the airless tires are offroad tires, so they're bigger, heavier, and don't accelerate as quickly because of that. I want to see a test of these on a vehicle they were made for, against BFG Mud Terrains or smth else with a similar tread and weight.
I'm curious how the airless tyres handle mud, when all that space inside seems like it would get filled up and jammed.
Funny how you said that cause they forgot that's off road tires😂
They are NOT off-road tyres... How do you air down for soft terrain.. With no air. You cant. They are not off-road tyres.
@@Ddog72 hm good point, that would be something I'd miss. Although, he did say they're designed for UTVs, and the lack of air allows the tread pattern to be flat against the driving surface - more traction and flotation.
We got similar airless tires in our Grasshopper lawnmower. Very expensive but sooo good compared to old tractor type tires. Of course it's not a car but some areas we mow are pretty off-roady so maybe that's worth something. The tire itself has some give by design so it increases the surface area compared to regular tire full of air.
Also for what I've seen they get softer with use which might help. If they're bad quality I think they might deform or get soft unequally making bumpy ride.
I can’t believe that suspension survived all those spacers🤣
RIP wheel bearings
Ngl, looks like a RC basher
Fr that leverage is insanity
I cant imagine the pain those wheel bearings went throgh in the process of this video.
I was just about to comment that
Bruh same thoughts here. Those tests are gonna put the life of the wheel bearings in jeopardy.
And the ball joints.
Imagine the side fumbling
lol no lie that was first thing i thought of when i seen him turn and all that flex fro tire to bearing with the spacers u can literally see it torquing on them in a not so cool way lol but its a miata so it can take anything lol 😂 😂 im not bias lol (drives a forged boosted NA miata) .. peace n love brotha keep it rad stay safe and build on
I think in the acceleration test the size difference is what matters the most. Those smaller tires can accelerate faster but have less top speed
straight out of mario cart
Exactly right, it's basic physics and somehow they didn't bother...
thank you
Thank likely has a lot to do with it.
Yeah, a weird oversight given they had a guy specifically there to talk about the science.
The radius and the mass distribution will affect the moment of inertia of the tires, which will affect acceleration and braking. The radius also affects the moment arm, which changes how energy is exchanged (by way of torque) between the ground and the car body through the tires.
The top speed issue, as far as I understand, is mostly a matter of the bearing friction. Smaller tires will require the bearings to spin faster. There is some inertia/momentum effect there too, where keeping "heavy" wheels spinning at a high speed may be easier than lighter/smaller ones due to that friction.
And then of course, it's odd that they would include rolling over a block in a timed test, which is very dependent on wheel radius.
These TH-cam titles could be so much better. There is always more content than I expect when I watch donut
They can't put it all in the title or there would be nothing left for the video!
@@andyortlieb3768 here's a clickbaity one " 100 year old tyre vs Future Tyres" or something
Yeah honestly I was more interested in the old tires than the new ones. It's only when I saw the short of them putting the Model A tires on that I realised it was in this video.
"Goofballs think 20" tire accelerates faster than 30" tire because of its name "
It's by design, Mr Beast talked about that. You make clickbait, to catch the viewer. Then you actually do it to impress the viewer. And then you one up it to make the viewer keep watching till the end. The algorithm loves audience retention on videos, so the goal is to stop them from clicking away.
Watching a Miata rollin' on wagon wheels is just what I needed to start my day...thanks Donut!
Wagon wheels? Are we watching the same video? Those old ones are from the likes of a Ford model A. A mass produced car with an internal Combustion gas (not grass) engine!
When Henry Ford designed the Model A,he was using what was available at the time. The most readily available tire that would work would have been from a horse and cart wagon.
@@johnathanedwards9054 those wheels and tires were mass-produced specifically for the model A and Model T. They are not leftovers from some horse-drawn wagon.
I can feel the pain those wheel bearings must endure.
It's fine if it's for science 😂😂
*RWB 911 has left the chat
The ball joints are 1000% SCREAMIN
Oh man it hoytz.
they must be trying to start a new money pit
You guys have always made great stuff. And yet, your editing and transitions etc are getting better and better.
Awesome work Donut!
it's great that Overdrive use a lot of subjects you do, and you guys come back with the ol' airless tyres on a small convertible topic. Both very different channels, so keep it up!
Those wheel bearings are stronger than most peoples relationships 😂
@@MrAlanmurphygood for you.
@@MrAlanmurphy congrats?
A year later and it’s still funny 🤷♂️
awesome transition at 5:04! hope to grow our channel as successful as you one day. great video
You mean a side by side? A transition is more like at 1:56

@@thesoundmajors9858 transition: the process or a period of changing from one state or condition to another.
@@thesoundmajors9858 it is a side by side tho. jerry recorded himself cutting the tire, then recorded the talking, and grabbed the tire from where he left it in the second recording lol
@@cmrnj what they did there is very simple to edit in idk what the hell u guys r goin on abt
I’m honestly amazed to not see one tire flying off 😂
This editing team needs an award man just 👌🏽😩
can we just take a second to appreciate that amazing transition on 5:04
its a side by side. its basically two videos layed over the top of each other
beauty job. Very creative and serves the point being made.
"Transitions" like that have been a long standing feature of the channel Aging Wheels. They can be pretty fun sometimes.
Transition? The people cutting the tire are just working super super fast 😂
I DIDNT EVEN NOTICE IT WAS THE SAME GUYYYY XDDD
Love to see Zach's Miata. That was a great series.
Dude!!! That format lately is just amazing!! All the best parts of donut ever, in every single episode 💪 hat's off for you guys
They tried those on a military humvee for a while and it worked really well.
That is the main purpose I suppose. Regular tires are better in almost every way, except durability. Which is exactly what you want in military application.
@@DG_427 that is to be expected the whole purpose of airless tires was to provide the military with a hardy tire resistant to gunfire or shrapnel and potentially NASA's vehicles who simply will not be able to be serviced after they are on the moon or beyond.
@@alexisrivera200xable The original Lunar Rovers had airless tires, they were made out of piano wires woven into a mesh. They almost look like a giant colander.
@@MScotty90 The lunar rover tires were also designed for a (210 kg) vehicle that weighed less than 500 lbs. on earth and less than 77 lbs. on the moon, and recorded a top speed (on the moon) of 11.2 mph (18 km/h). They'd barely function as bicycle tires on earth.
@@MScotty90 Yes, you are correct, a couple of years ago Neil DeGrasse Tyson got to ride a bit on a prototype with a similar concept tires made wit a mesh. It looked interesting.
The running over the nails on purpose is the same feeling for me as nails on a chalkboard
nails on a chalkboard is a sound not a feeling
Wow for me it’s the opposite. I find it very satisfying to see nails puncturing through rubber.
And nails on a chalkboard IS absolutely a feeling.
Love the content, very cool to see these tests, also, those spacers, ouch, I thought me with my 1/4 inch old spacers on my Lincoln were sketchy! Love how the suspension held up..
Your videos r so informative and you guys prolly have the best edits i have seen on yt
They should have used modern tyres that are the same size of the old ones, since both old and airless tyres have the same size, so they wouldnt have been any advantages like small vs big ones. I know that they could have more hard to find since the unsual size, but if they wanted to do a real comparison they should've done that, but still great video 👍👍
Yea. Also, the spacers being so far out make the future tire sit on the inside edge of it so it isn’t performing how it was designed to.
@@3.0colorado21 the future tires sit on like 25% contact.
They didn't really do like smaller wheels much 100y ago though. Maybe for a midget car or something. The bigger wheels made it smoother to ride on the crappy roads.
Not only the additional height, but they have additional weight. Which really effect the performance that they are tracking
@@ryurc3033 And not only the additional weight, the modern tires being smaller in diameter essentially gives the car lower gears, which is going to be an advantage for something that doesn't have a lot of torque at the crank.
They were comparing the future tires more to the past tires than the current ones, so it makes sense to use large future tires. A more valid complaint would be that they should have used a pickup or SUV for the test so that the wheels could be mounted in the wheel wells rather than needing spacers.
Could have swore I heard 1948 Model A tire. Ford stopped using wire wheels in 1935. That was when they switched to the"wide five" safety hub and steel wheels that became almost universal equipment in early stock car racing. Also the last year for the model A was 1932. Edit; some of the reason your modern tires out accelerated the other two was due to the smaller circumference of the tire.
Appreciate the editing as well top notch production 🔥
Tweels are also fantastic on skid steers since they act like suspension. It will be interesting to see if they do perform better when street legal versions come out.
pretty much every lift i see have these now, esoecially forklifts and telehandlers
@@samssa7813 i haven'r seen them yet on skid steers. I have on zero turn standing mowers.
Doubt there will ever BE street legal versions of these. This style of tire has been around for years and always fails to match modern tire performance, just as you can see here. They're practically only used on construction vehicles where not deflating is a much larger issue.
the reason why the modern tires out performed the others is because they have been engineered and tested to get the best results for a range of harsh tire conditions. Thanks for the video it was interesting to see how the old performed vs the new
“Future” ones are ugly anyways
Just wondering for the acceleration test, were the current day tires also 30+''? As I feel like the effective gear ratios would affect accelleration far more than rubber and contact area as I didn't see any loss of traction in the videos.
Stop with the realism 😂😂😂
Yep. That's what I came to say as well. Not really a fair comparison changing wheel diameter.
,,, don't .. dont do that man just enjoy the video. it was cool not 100 percent man sheesh.
Yep, I came to say the same thing.
@@crewtheaftermath4105 sorry, didn't mean to spoil it for anyone. I just couldn't see for sure myself.
I havent watched in acouple years cant believe the sucess! Love to see it!
Donut is finally headed in the right direction again. I like how this video combines aspects from everyones previous respective shows
This is one of the funnier ideas you've come up with 👍 Thank you for the videos. More B2B and D-List please 🤗
Base stock Jeep or similar like a Bronco or 4Runner would have been a better choice for this test. You wouldn’t need so many spacers and also the design is closer to model A and the type of vehicle in mind for airless tires.
I agree. Weird choice with the miata
I love the editing in this video. Top notch 👌🏻
Tire Streets and Donut Media collab when?? 🤔 They've got all the Acceleras you'll ever need.
“They hated lateral G’ back then” James finally said a joke i laughted at
I cannot explain how happy it makes me to see the Miata back
My favorite part of the video was Jeremiah going all science and engineerin on me. Love that shit mate!
This is the first good content I've seen from this channel in a long while
There are so many variables in this comparison that it really isn't even coming close to making them equal. Good video to see some comparisons. It would not be cost effective to try to do an apples to apples comparison. It is good enough for a simple demonstration. I am a fan. Love what you guys do. keep it up!
Remove uneeded spacers, keep better consistency with paths and control of the car. Then it'll be a bit better of comparison. Fun video to watch, not great for good comparisons. Which seem to be a lot of their videos.
Really great! Nice editing! super fun and informative.
Those "future" tires might be slower, but did you see how it handled offloading? The benefit I see of airless tires is more travel. Like suspension in your wheel.
I think once the materials and processes to make those things gets figured out, airless tires will be a godsend for folks who drive off road, or on roads with a lot of potholes. (every country road)
Airless tires will never work, we have been trying for the better part of 100 years, it isn't a new idea, just like all of Elon Musk's "ideas".
See: th-cam.com/video/jQ05RbGa0zM/w-d-xo.html
The only way airless tires can work is if there's a world altering materials engineering breakthrough, the way I see it.
It should do great. I do want to see how the design would eject mud and snow from inside the tire. It could go off balance quickly
This why mowers have them. These help soooo much on hills
can't wait for icy off-roading
wonder how those would fare
This was sooooo funny. Thank you for making the best videos.
Sick video and amazing editing
those old tires were actually made to be able to off-road because at the time “paved” roads were rare. it made sense to see it go off-road and over the curb the best out of the 3.
I pray for that MX-5, went through some torture with all those spacers.
Bearings be in some real pain.
Nice video though, wasn’t really aware of these airless tyres before now. Looks a cool concept with more development needed.
To those in the know, how far do run flats like on some BMWs fair here? Yes they only *should* be driven on for X miles after a puncture, but they do help alleviate the puncture problem temporarily with modern air tyres I guess.
Would be cool to see a donut video on runflats!
@Max Power how do you mean?
I thought runflats functioned like normal tires do they not?
8:25 Is it just me or does it seem like there's a fair amount of air between those polyurethane spokes?
To me it looks like a fan it probably sucks air lol
Love it, lawnmower tires on a Miata haha. Can't wait for y'all to test the road tweels when Michelin makes them public.
The editing skills on this one are 🔥🔥🔥
I can’t imagine the pain that those wheel studs just went through
It's really cool to watch donut media grow from mainly info and history in a straight forward yet still entertaining, to a company that actually provides better tests then the current version of top gear without Jeremy, may, and Hammond. Plus the podcast and hi low projects, they have learned how to juggle multiple really good projects. ❤️⛽🏎️🚓
5:50 they ABSOLUTELY knew what they were. 😂
the editing on this was dope!
I would like to see how the airless tires react to really muddy terrain
Probably would suck tbh.
Mud would fill the groves and cause the tire to weigh alot more. With a Miata you’d feel the strain in the engine to spin them
@@Dusty.Does.it. But that would happen with normal off road tires too. Not really an airless tire specific problem.
@@seraphimvalkyrin4543 there’s much more empty space that can be filled using the “future tires”
They have show them with normal looking sidewalls to keep things out of them. Maybe that will actually be an option
and rocks getting inside them lol
i loved the passing the tire transition
Could you imagine if you end up filling the airless tires with mud and sand?
I would think the increase in tire size would change the results massively, not just the year or design of the tire
Puncture proofing isn't the biggest advantage to the airless tires. The biggest advantage is the ability to tune ride and handling separately. Because of the way those spokes work it is possible to make their lateral stiffness and longitudinal stiffness different. So you can have a really soft riding tire on your Miata without losing any cornering ability.
Definitely good for the purpose they’re built for, but not for on the road
Pretty slick editing there Donut
I saw these tested on a hmmv in 2000. They destroyed like 50 sets on sand. It’s kind of interesting to see how far they have come
These edits maaaan, props to the editing team and director :D Love IT!
don’t know what i’d do without donut
8:30,Makes 0 sense about air transferring heat. The future tires is literally a heat sink and a fan combined when moving. 😂
It would be a better test if the tread types and patterns were all more similar.
Also larger diameter tires are more difficult to stop
5 min silence for those who are still waiting for turbocharged miata
What do you mean?
Did my first oil change on my truck and wore Donut hat to recycle old oil. Guy recognized it😎 thanks donut
This videos are always so entertaining. Keep it up
The key thing I don’t see the future tires overcoming any time soon is the ability to adjust tire pressure to suit auto weight and driving conditions. With current tires I found that I get the best traction when I am a couple psi over recommended on one axle and a couple psi under on the other. On my truck I’ll lower the pressure for sand or snow… None of that can be done with those solid tires.
It's not quite true that you can't adjust the "pressure" with airless tyres. There are a few versions that do allow that and it's done through adjusting the spoke tension.
This would have some advantages over standard pneumatics since you can stagger the compliance to make a round tyre more star shaped, effectively giving you more paddle-like effect which would be tremendous in mud and certain situations on sand, even rock climbing. Would obviously take longer since you need to adjust multiple bolts but airing up with a run-of-the-mill compressor takes forever too. Also side note, I'm not quite sure why you're ever over-inflating on the track, that reduces your grip.
The question is whether that going to be among the first models of these tyres released and I doubt it. I imagine it would be a long way down the line. Off roading is a niche compared to the commuter market. 99% of people never need to air down their tyres, even just in the emissions savings from underaired tyres and the safety benefits of avoiding overaired tyres and blowouts makes airless seem like a good option.
You'd get less traction by over inflating
Ah nothing better than a donut media video in the morning
It’s 14:20 here in Austria. Best thing to watch donut media after school
I see all around my city that aerial work platforms on construction sites already uses these kind of tweels for the last couple of years
Love seeing the willow springs track! goped races!
How is no one talking about the great editing on this video? Donuts put in quite an amount of effort on this
I glad to see Zach his Miata again on dount media show
I'd like to see airless tires vs mud.
You guys really make my day!!
I think my biggest possible issue with those airless tires is weight, you would need to make them per car model and they'd struggle to account for large changes like adding aero, loading up cargo, running with multiple passengers so on so forth.
This Miata has what can only be described as "A Whistling Diesel amount of wheel spacers" lol.
Yes donut this is what we like to see
“That’s right jerry you tall glass of brains”. Y’all are fried af 😂
For the airless tires, isn't it the ribs that are more likely to overheat (due to repetitive flexing) rather than the tire tread itself? With the open design, you could dissipate the heat rather quickly with that much surface area exposed and air being pumped in and out when the tire deforms.
Yeah, they said it wrong with the reason for overheating... Air is actually a better insulator than plastic and in a tire, air doesn't "help disipate heat" - the airless tire actually has much more cooling due to its sides admitting cold air from outside. What overheats the airless tires is the rapid flexing and stretching of its spokes and obviously the heat combined with cyclic deformation is what makes the spokes fail. In a traditional air tire, the cyclic deformation is much gentler and air as a "spring material" doesn't wear out. I'm pretty sure the airless tires also impact fuel efficiency - if you have two tires and one of them runs hotter than the other, that means it's converting more of the engine energy into waste heat at the expense of motion. That's obviously the reason why it achieves worse times on the Miata.
I like the idea of airless tires. I know they won’t have nearly as much dynamic ability as regular tires but they seem like they make good sense for most cars, although the fact that they don’t brake as quickly as regular tires is something that needs fixed before they can sell them to most consumers.
At first I was like why would they need to fix them if they last longer? Then I remembered profit has to be made.
@@asandax6 he says brake, not break. Important difference!
@@guillermo_fdez7997 Ohh my bad. Someone call Mr Beast I might also be blind.
they just need to be adding anchors
I never thought i would be interested in watching a video about tires
Long ass Spacer I’ve ever seen 😂 fire tho 🔥
Donut hiring some wizards for their videos now. Looking slick. Great Video!
I'm assuming the camber angle was affected by the adapters, I'm curious if they would perform better if adjusted for their widths and diameters.
Camber was because of the massive spacers acting like a huge lever on the suspension and making it sit lower
Sweet script, graphics and editing boys... loved the video!
Great production on this
Smaller tires have an advantage also because they're smaller so it's like to have a shorter gears respect to the bigger ones.
They should have just made spacers for a modern tire (of equivalent diameter) and the old tube tire, to fit a razor side by side. Would have been a much more useful and accurate comparison
No. The center rotation will be the same making bigger tires circumference move faster to keep up with the center speed.
22 inch tire multiple by 3.14 is the measurement of how far the trip moves in one rotation
30 inch tire by 3.14 is more than a smaller tire making the bigger tires have the advantage.
@@alexislaisney3404 Bigger wheel = higher top speed with less torque. This isn't a problem when you have lots of torque on tap, but it's a Miata. The OP is correct that smaller tires are effectively a lower final drive gear.
@@alexislaisney3404 sorry, you're reasoning in the wrong way: it's the engine the source of power, not the tires. Bigger tires = with 1 rotation (from engine power) you move the vehicle further. Since the engine has the same power regardless of the wheels, and the same reduction ratio at the gearbox, and bigger tires = more space at the same angular speed, then either you need more power or you'll be slower. Exactly like a higher gear ratio. And do you accelerate faster in 1st or 2nd gear?
I think Money Pit just earned a new nickname: the Water Strider cuz that's what it looks like with the wheels 6' from the bodywork 😂
Money Pit Miata* :P

Is it just me, or is James kinda Diva'ish in this episode? You can tell he's making big TH-cam 💰🤑. Good for him and all of them.
That spacer setup is terrifying😂 Am I wrong for thinking it actually looks pretty good with the Model A wheels on it though?
Lookin like something from Mario Kart and I love it
@@centuryhelix8727 LOL I could see it!
But the real question is: Wagon Wheel MoneyPit Miata in FH5 when???
0:45 There are no problems mon, just situations.
I think the reason why the airless tires didn’t perform as well as the ‘modern’ tires is because you were using an off-road tread pattern. That type of tread pattern is great for off-roading, but aren’t too great on paved roads, plus they tend to be a bit noisy when driving on paved roads.
I don't even have a car, heck even a license, but I still enjoy watching "Do" go "Nuts" - cheers from Germany!
I love the videos like this. It's always disappointing when a video this interesting and cool is only 11 minutes long 🙁 I'd think each tire could have at least its own 20 minute video. But I'm also not the one that built and runs one of the top automotive reporting/entertainment outlets that's out today.
I think they changed their style of content to be more fun and short than informative
I actually enjoy videos that are about this long. Easy to fit into a busy day.
this video was sponsored by modern day big tire co. don't trust anything they say. Future is the way to go.
If anything slower speed = safer for pedestrian
One invention that can't be reinvented, it's just perfect
I’ve seen these tires irl the mowing company that mows are yard for us temporarily until we get a new lawnmower. Has 2 airless tires on the drive wheels of the zero turn mower.
