I think 35' is going to be the highest optimal level for the vast majority of jeep owners for a real all-rounder tire to take 99% of trails while still remaining viable on-road. 37s and 40s I feel are for hardcore enthusiasts. Nothing wrong with that, but I think the majority of jeep owners don't really need anything higher than a 35'
I'm running 38" Nitto Trail Grapplers on my 2019 manual Rubicon. I have a 2" lift and regeared to 4:88. Chromolly axel splines as well as trusses. I live in Colorado so the rocks here require some clearance. I'm very happy with my set up.
I’ve been happy with my 285/75r17s on my 16 manual Rubi. If I ever regear I might go up to 37s, but for now these seem to be the ideal all around tire size for 4:10s and a stick for a Jeep that has to daily.
Been wanting a Jeep for years and finally got one this past September!! I’ve been reading and researching and I think a 2” spring lift and true 33” tires are the perfect match! Cooper STT Pro as well they are amazing tires
I've done a 2.5" lift and true 33"s on my Aus spec JL Rubicon and it works great but be aware there was a noticeable drop in torque over the stock 255 / 75 /R17's and fuel consumption has been increased about 30%. If you get wheels have a look at the Icons with the innerlock system they're amazing, I ran all day yesterday at 10PSI.
I'm running 35x12.5x17 on my 2022 JT max tow 4.10:1. Added Mopar lift, new HD track bar and Fox steering stabilizer. I recalibrated the speedo and shift points and rides great looks badass and see 8th gear every day. I think 37s look great but don't want to regear and still want some performance.
Will it pull 8th on 80mph+ freeway with a headwind, or is starting to get really picky on where it grabs 8th? I'm thinking I90 across South Dakota. Always a cross/ headwind headed west and lucky to get 14mpg in a stock Wrangler in those conditions.
@@scootypuffjr. I haven't been in those identical conditions, and usually don't drive faster than 75. That being said when I do hit 75 shes in 8th most of the time.
2021 Jeep Gladiator Mojave 410 gear ratio with 2" AEV spacer kit with AEV geometry correction brackets running 17" Black Rhino wheels and 37x12.5 17 tires. also installed a Tazer to calibrate the speedo & eliminate any tire pressure lights coming on the dash. all good, no rubbing, and power feels normal. the only difference is gas mpg was affected slightly.
100% agreed! I have the same on my 22 gladiator rubicon (except mickey Thomson baja boss at's) and it just looks right...like it should've from the factory
Used to run the trails with a guy who had a JLU on 37s. Stock sport with a 2" spacer lift. He took the fenders off completely and put stubby bumpers on it to give clearance. Somehow that thing did just fine. His problem was constant water crossings with that 3.6 liter. The aluminum couldn't handle constantly heating up and flash cooling. Cracked the block twice. Insurance covered it the first time. Crazy that the engine went before axle and suspension parts.
Damn!!! may i ask what year? i guess my 35’s will do with my 3.5 lift. before jeep i used to own a buick encore…omg the transmission issues were TERRIBLE!! jeep has treated me well. i had a patriot before i got my wrangler (i still daydream about the patriot & the stock upgraded sound system ) but the wrangler definitely is something i can go completely off road with no regrets 🎉😂
I found that my 38” Nitto Ridge Grapplers were the sweet spot on my Gladiator Rubicon with 3.5” Clayton Overland lift kit. Gives me about an inch or two clearance on 7 ft garage limits. So home and airport garages are still doable. I’d live 40’s, but would no longer fit in garages without dumping air pressure.
Looking at a Gladiator. This is a perfect video. I have to travel for work but also want to do light trails on the weekends with the wife to take pictures with our drones. 33s seem like they give me the best balance since I'm on road way more than off.
For me, it's getting a breakover angle on the long gladiator wheel base. I was turtling on small whoops. Luckily I was able to back off. But adding 2.5 lift with 37" BFG KO2s on a Gladiator Mojave, I got 28.5° and haven't been stuck since.
I’m running 35 toyo mt open county on my sport jl stock I have a lot of clearance you don’t need any spacer or non modifications you’ll run fine trust me
I’ve tackled some pretty awesome stuff in my JKUR, I’m on 35s with a 3.5” lift and can I keep up with guys on 38s & 40s on what I’m ‘willing’ to tackle. Lol. Seems like going any bigger would only be if I wanted to flirt with body damage. 35s or 37s are great for off-roading and will get you through pretty much everything short of causing body damage out here
@@ianparsons8894 I run 32x11.5r15 with a 2.5 inch lift. I had 33x12.5r15s on it, and I much prefer the narrower, lighter tire. It just handles better and it looks almost identical.
I just put on some “Micky Thompson 37’s”…. It was a perfect fit…. Perfect for a picture… My pinky finger was the space available between the tire rubbing along the metal railing on the length of the jeep… To much rubbing between the tire and metal. This was on a 2.5 inch lift…(you will need something higher) I am going to have the metal cut away to prevent the rubbing… I wish I could provide a picture… The tires do look beefy and it is a great look to the 2010 jeep wrangler rubicon….👍👍
Yea you’re gonna want tires over 34” if you spend more time off than on road. If you’re a commuter and spend at least 70-80% of driving time on the highway, a taller tire will have a detrimental effect on highway and city mileage, not to mention speedometer errors. I recently bought a new 2024 Gladiator Sport S, we bought for our daily driver for my wife and I who are both retired now. So we don’t need to go off road much at all, but like the style, comfort and adventure capabilities we might never need. So the 245/57-17 Bridgestone Dueler tires are fine, very quiet and ride very well, all while returning the best overall mileage and on road traction, especially in heavy rain. That we get often in Central Florida.
Ran a set of nitto 40x13.5r17 like your blue jk for 8-9 years on the factory Rubicon axles with chromoly rear shafts after bending one and tubed and gusseted front axle from the beginning with 5.38 gears. Love those Nittos but went to procomp this year due to availability
You didn't mention axle ratios as you get to 35" and 37" tires. Also mention the relation to tire outside diameter to wheel diameter. Having more tire to wheel helps until it gets too great then tire/wheel spin contact a t low pressure is a factor in non-fastened whel/tire assemblies.
KO2 are notoriously small. A large true to size 35 will look much closer to a 37 KO2. Likewise, a 315 (slightly smaller than a 35) KO2 which already runs small will look much smaller next to a normal or true to size 37. . People should really research the sizes of the specific tire they want to run.
I have a 2012 JKUR and when I put my 37's on I had a 2.5" Rock Krawler lift and it rubbed in the back. I had to cut/trim/hammer the pinch welds and even that wasn't enough to stop from rubbing on the stock bumper. I've put on longer Rock Krawler springs and haven't had any issues yet.
Very comprehensive video. I’m new to the Jeep world just got a 23 Gladiator Sport S. Not planning to do much but I think the 33” with the level kit is where I’m heading.
Sounds like a good plan, another option is to throw on a set of flares and you could rock the 37" with that same leveling kit. www.quadratec.com/p/quadratec/baja-hd-fender-flares-gladiator-jt-12510-5231
Great video, guys! Yet one more opinion: The curve of associated expenses really does rise exponentially as tire size increases. 33's or 35's will get you to 90% of the places you want to go, assuming your driving skill rises to the occasion. I run 37's and they are utterly amazing offroad but make most conditions quite easy, maybe too much so? And I have to drive like I'm wearing ballerina slippers on stock axles to avoid breakage. So is the answer 1-tons ($$$$$)? Or smaller tire and try harder? Depends, but either is an equally valid AND ENJOYABLE path.
Great video! I run 35x10.5r tires on my Gladiator Sport S with the stock wheels, stock suspension, and stock fenders and have no clearance issues at all. I’ve been considering bumping up to 37s when these wear out, but I’m not sure if I want the extra MPG loss
In my experience, if you go that big on a sport model, you might find the gearing to be an issue. Just make sure you consider it before making a commitment.
That 40in tire is unique because you cant find that design on the manufacture website, the one in this video has a sidewall that has a sidewall, very aggressive side look
Could you get by with 34-inch tires w/ 16 or 17-inch wheels on a Wrangler Sport or Sport S/Willy's w/o having to re-gear or upgrade any suspension components?
Is it lifted and do you know the gear ratio? From the factory mine didn't have a great turning radius because of the length compared to my 04 TJ Wrangler I traded. I would have kept my Wrangler but the frame rusted and broke in a few places but I'm not looking back because of the bed function. I have 37's and a lift but my turning radius hasn't changed. I hope that helps
Nice video, Rob! I've got a set of Quadratec Hardrock Wheels with LT315/70R-17 BFG KO2's on order from you folks for my 2021 Rubicon Gladiator, can't wait till they are delivered!
I think the information at 5:56 is incorrect. A 315/70/R17 would be about 35" diameter, but would be a ~12.5" width, a big difference than the 11-11.5" width stated here. A stock Sport or Willys with stock wheels shouldn't have a problem running a 35/11.50/R17 tire, but as stated, the wider 12.50" wire is likely going to need spacers to avoid rubbing, or at the very least a wider negative offset wheel. I've been researching into this a lot myself since I have a 23' JLU Willys, and I want to keep my stock wheels, but go to 35" tires. I found that 35"x11.50" should be fine, except under a heavy flex there may be some rubbing. I'm personally looking at the Falken Wildpeak AT4W in 35x11.50R17
Today I want to go look at some tires from my previous dealer in Hilltop Dodge Jeep ram I got a jeep wrangler on stock. I wanted to get some beefier tires like more meat instead of the original ones I looked at the Falken nitto toyo Bridgestone BF, good rich, TAKT BF, good rich Terrain t/a Mickey Thompson destinations and many more the guy told me that I could fit a 33 inch tire. Originally the stock is like 31 but I wasn’t sure so a 33 inch tire can fit on a jeep wrangler without a lift kit. what brand do you recommend? Like how the mud tires look I need some off-road tires that look similar to that I have the Falken wild peak in mind but I was so indecisive. I was tired of looking at tires, but I don’t want to buy a new set of wheels rims.
@@DoubleZippea NICE! You can fit 35's on a stock JL, they will fit. However, you will the tires rubbing often if you go off-road. 33's will do the trick for you as long as you don't get a bigger rim than what you have now. You don't need a lift and the 33's will give you that look you want. For the money you can never go wrong with BF Goodrich Mud Terrain tires. Personally I would get 33x12.50. You may need wheel spacers so you don't rub at full turn but it depends, you may not also. If you need more info just hit me up and I can help, This is what I do for a living Aaron
Running 38s on mine being doing some good rock crawling for a while, moving to "lightweight" 40s Tomorrow. Mine are built though Trussed, C gusset, RCV up front and chromolied rear on 4.88 gears. JL D44s are about 43% stronger than the JK one based on thickness and length. The longer the axle, the stronger it is. But they do have a major weak point = the FAD area. That's why you want to RCVs it with a three piece RCV or get rid of the FAD and get two-piece chromolies.
I have 35 on my Sahara which I don’t like because it not a smooth ride. I feel all bumps I’m thinking of going down in size. I have a lift so it’s enough room to go down in size. I like the big size wheel look so I don’t wanna go down in size to much. Any advice what size would be best for smoother ride?
I have been told that Jeep will not honor their warranty if any tires are larger than stock. My 2020 JT stock is 255-70-18. I have 35-12.5-20’s on it. It rides and drives like a dream with the 2.5 lift. But what about towing ? My Overland has 373 gearing. Am I safe with 3500lbs trailer ?
There is the best 35, 37, 40 as 35-40 good for on uphill, downhill, mountain, mountain road, and mudding. But depond on they can kill yr gas, oil miles, brake pad, and easy make catalogs pipes too heatstroke.
Might I ask how you recommend tire rotation for the 35" and 37" size tires? [1] A simple front to rear and rear to front move or [2] X the fronts to the rear and a simple rear to front move. Many Thanks!
In need of some help. I recently bought a 2016 Jeep Wrangler unlimited Sahara jk that has 225/75/17 tires on it. I want to upgrade to an aggressive tire with a little bit more height, without using spacers or lifts. Do you have any tire suggestions for me? I don't really go off road , it's more for look and snow. The jeep originally had 18inch wheels, previous owner put 17in wheels on it, that's what I have now.
Thanks Rob. Qtech has pretty much everything including gear ratio upgrades and one can build a quite capable vehicle with your PA warehouse even for an old fart like me
The tire size if often larger than the actual tire dimension. Most brands say 37" tire is actually 361/2. Not many are the actual size. Interco tires are actually larger then the size listed. 38" super swamper is actually 38 and 3/8". Read the fine print.
So it's okay to put 37s on my stock axle jeep wrangler sport with overland gear such a tent awning alot more stuff currently having 35s wanna run 37s but axle cost alot money lol.
Question... if a wheel is r17 fits a 70 side wall on 1 tire its a 33 inch and the 35 inch also has 70 side wall with r17??? How ?? Im from europe so need to understand these number's
Depends what it came with. Put it this way, Jeep gives you 3.42 gear standard, 3.73 with Rubicon, and 4.56 gears with the Extreme Recon package for it's 35" tires. One or two sizes up from stock will be ok. But you won't be happy with 35's on a 3.42 gear. Edit: 4.10 in new Rubicons ( thanks @ Attniel Thomas)
@@mattbrew11 the engines all have roughly the same output. The real question is: Do you want a mall crawler, or do you want it to perform? A JL Sport, Sport S, etc., with a 3.6l 8 speed auto with 3.42 gears and a slightly larger 285 tire is already starting to use 8th gear less than optimal.
See I hear different things about the 33s … I hear you can put them on a sport with no problems then I hear people saying you can’t because it rubs . I’m trying to figure out which to get but don’t want to make the wrong decision !
I think 35' is going to be the highest optimal level for the vast majority of jeep owners for a real all-rounder tire to take 99% of trails while still remaining viable on-road. 37s and 40s I feel are for hardcore enthusiasts.

Could you get by with 34-inch tires w/ 16 or 17-inch wheels on a Wrangler Sport or Sport S/Willy's w/o having to re-gear or upgrade any suspension components?
I just bought a lifted jeep gladiator with 37's and the turn radius is terrible, been thinking about going to 33's or 35's video helped alot, thanks
Is it lifted and do you know the gear ratio? From the factory mine didn't have a great turning radius because of the length compared to my 04 TJ Wrangler I traded. I would have kept my Wrangler but the frame rusted and broke in a few places but I'm not looking back because of the bed function.
I have 37's and a lift but my turning radius hasn't changed. I hope that helps
Nice video, Rob! I've got a set of Quadratec Hardrock Wheels with LT315/70R-17 BFG KO2's on order from you folks for my 2021 Rubicon Gladiator, can't wait till they are delivered!
Thanks! Those will look great on your Gladiator!
I remember back in the day 35’s were the big dogs ish, now it’s as if they are like a 31” tire lol.
What about the 16inch tire and wheel. I'VE got a 2013 jeep wrangler sport 4x4 and I'm going to put a 285 70 16 on it in a little while down the road.
When you jump to 37s you should be upgrading the axles.
Agreed. If you are wheeling, likely you’ll be upgrading them wether you want to or not.
@@Quadratec and 38, 39?
I think the information at 5:56 is incorrect. A 315/70/R17 would be about 35" diameter, but would be a ~12.5" width, a big difference than the 11-11.5" width stated here. A stock Sport or Willys with stock wheels shouldn't have a problem running a 35/11.50/R17 tire, but as stated, the wider 12.50" wire is likely going to need spacers to avoid rubbing, or at the very least a wider negative offset wheel. I've been researching into this a lot myself since I have a 23' JLU Willys, and I want to keep my stock wheels, but go to 35" tires. I found that 35"x11.50" should be fine, except under a heavy flex there may be some rubbing. I'm personally looking at the Falken Wildpeak AT4W in 35x11.50R17
I just bought a 2020 sport came with Mickey Thompson 35 x 12 .5 on 17 inch rims so far I have no rubbing issues whatsoever and rides pretty nice
What do you think about 18" rims
32”s are now all the rage - good terrain, no lift needed and way cheaper than 33’s and 35s.
I did 20 inch rims with 33 mud graps, I'm thinking about doing a 2" lift with 35 mud graps next
Nice!
I have a 20 Prius. How big can I go without cutting fenders and re-gearing?
How about a little more info on wheel offset?
Today I want to go look at some tires from my previous dealer in Hilltop Dodge Jeep ram I got a jeep wrangler on stock. I wanted to get some beefier tires like more meat instead of the original ones I looked at the Falken nitto toyo Bridgestone BF, good rich, TAKT BF, good rich Terrain t/a Mickey Thompson destinations and many more the guy told me that I could fit a 33 inch tire. Originally the stock is like 31 but I wasn’t sure so a 33 inch tire can fit on a jeep wrangler without a lift kit. what brand do you recommend? Like how the mud tires look I need some off-road tires that look similar to that I have the Falken wild peak in mind but I was so indecisive. I was tired of looking at tires, but I don’t want to buy a new set of wheels rims.
Stephanie do you have JL?
Yes
@@DoubleZippea NICE! You can fit 35's on a stock JL, they will fit. However, you will the tires rubbing often if you go off-road.
33's will do the trick for you as long as you don't get a bigger rim than what you have now. You don't need a lift and the 33's will give you that look you want.
For the money you can never go wrong with BF Goodrich Mud Terrain tires. Personally I would get 33x12.50.
You may need wheel spacers so you don't rub at full turn but it depends, you may not also.
If you need more info just hit me up and I can help, This is what I do for a living
Aaron
Thank you so much 😊
@@DoubleZippea Yeah anytime. Always here to help just ask away.
Aaron
I wonder where you got the idea for this video??? Awesome content, Godspeed!
Who does that work for the average person? Where do you usually take your jeep for this change?
How would these tire affect the engine and the gas mileage?
Any one on how the Dana 44 will hold up? If you realy take it hard core, it might fall appart. Road warrior, limitless
Running 38s on mine being doing some good rock crawling for a while, moving to "lightweight" 40s Tomorrow. Mine are built though Trussed, C gusset, RCV up front and chromolied rear on 4.88 gears. JL D44s are about 43% stronger than the JK one based on thickness and length. The longer the axle, the stronger it is. But they do have a major weak point = the FAD area. That's why you want to RCVs it with a three piece RCV or get rid of the FAD and get two-piece chromolies.
So a 2014 Rubicon with a 4” lift can handle 37s without needing to change anything else?
Thanks for the video. If I may ask could you in an upcoming video talk about portal axels?
Thanks again, 👏👏🙂🙂
38s on a 18" wheel is the best overall combo.
Nope, 17’s have far more wheel and tire options. Less weight.
I have 35 on my Sahara which I don’t like because it not a smooth ride. I feel all bumps I’m thinking of going down in size. I have a lift so it’s enough room to go down in size. I like the big size wheel look so I don’t wanna go down in size to much. Any advice what size would be best for smoother ride?
I have been told that Jeep will not honor their warranty if any tires are larger than stock. My 2020 JT stock is 255-70-18. I have 35-12.5-20’s on it. It rides and drives like a dream with the 2.5 lift. But what about towing ? My Overland has 373 gearing. Am I safe with 3500lbs trailer ?
I heard a lift voids warranty as well
There is the best 35, 37, 40 as 35-40 good for on uphill, downhill, mountain, mountain road, and mudding. But depond on they can kill yr gas, oil miles, brake pad, and easy make catalogs pipes too heatstroke.
Thanks for the video. Can we use larger than 17" wheels?
Might I ask how you recommend tire rotation for the 35" and 37" size tires? [1] A simple front to rear and rear to front move or [2] X the fronts to the rear and a simple rear to front move. Many Thanks!
Corner to corner. Left front to right rear and vice versa
So I can fit rubicon tires on my stock lifted Sahara without rubbing
What kind of bumper is on the Jeep with the 37s
In need of some help. I recently bought a 2016 Jeep Wrangler unlimited Sahara jk that has 225/75/17 tires on it. I want to upgrade to an aggressive tire with a little bit more height, without using spacers or lifts. Do you have any tire suggestions for me? I don't really go off road , it's more for look and snow.
The jeep originally had 18inch wheels, previous owner put 17in wheels on it, that's what I have now.
Who makes the wheels on the 37” tires?
Thanks Rob. Qtech has pretty much everything including gear ratio upgrades and one can build a quite capable vehicle with your PA warehouse even for an old fart like me
Will 275/70/r18 KO3’s fit on my stock 2024 Sahara?
What winch bumper is that on the front of the Blue Wrangler on 40's...??
So, no 285's on a stock Saraha then without some modification of other things?
Would it be worth it putting 40s of you don't go off road. Have 40s just for the looks?
Great Job. Love the new JL that had the old YJ grille.
Thanks 👍
What about for a Grand Cherokee Trailhawk 2018?
Would really suggest regear at 37s
It's always a good idea, but depending on your gears from the factory you don't HAVE to.
The tire size if often larger than the actual tire dimension. Most brands say 37" tire is actually 361/2. Not many are the actual size. Interco tires are actually larger then the size listed. 38" super swamper is actually 38 and 3/8". Read the fine print.
So it's okay to put 37s on my stock axle jeep wrangler sport with overland gear such a tent awning alot more stuff currently having 35s wanna run 37s but axle cost alot money lol.
What is the name of the wheel the 37” tires are wrapped around? It’s pretty close to what I’ve been looking for
Amazing how much power you lose going up in tire. You can only regear so much.
This is just the video I have been looking for. Thanks for advice 🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧👍👍👍
I want to know more about that green Rubicon center caps
Question... if a wheel is r17 fits a 70 side wall on 1 tire its a 33 inch and the 35 inch also has 70 side wall with r17??? How ?? Im from europe so need to understand these number's
what about regear ?
Metric tire sizing is just unnecessarily complicated.
It really is. Most of the 33s in metric for me are closer to 32s that are an inch thinner than the American made 33-12.50r17
👰 you can try use .. giant tires dump truck
I wish they were all non rubicons because they already have higher fenders
Will 35s fit a 4xe Willys without a lift?
Yes!
I am going with a 20 inch rim whats the biggest 20 inch tire I can use
i heard u can put helium in the tyres
I have a 21 JL Sport.. I like to put a set of 35s on my Jeep would I have to change the gears to do that?
At what size should you consider re-gearing?
Depends what it came with.
Put it this way, Jeep gives you 3.42 gear standard, 3.73 with Rubicon, and 4.56 gears with the Extreme Recon package for it's 35" tires.
One or two sizes up from stock will be ok. But you won't be happy with 35's on a 3.42 gear.
Edit: 4.10 in new Rubicons ( thanks @ Attniel Thomas)
Depends on engine, transmission and where u drive it most often
@@mattbrew11 the engines all have roughly the same output.
The real question is: Do you want a mall crawler, or do you want it to perform?
A JL Sport, Sport S, etc., with a 3.6l 8 speed auto with 3.42 gears and a slightly larger 285 tire is already starting to use 8th gear less than optimal.
@@scootypuffjr. I have a gladiator diesel. It pushes 39s around effortlessly on and off road
@@mattbrew11 39's on stock axles and gears. Must not be pushing as hard as you'd like to think.
See I hear different things about the 33s … I hear you can put them on a sport with no problems then I hear people saying you can’t because it rubs . I’m trying to figure out which to get but don’t want to make the wrong decision !
