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.
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.
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’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.
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
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
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.
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.
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
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.
@@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.
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
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
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.
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.
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.
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 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.
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
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!
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?
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
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 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
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.
Aren't you forgetting something? Anything above stock will alter the speedometer which will require a new speed gear to keep the speedometer reading correct. Great video, very informative.
Great video! I have a question, if I put the 35' on my stock Rubicon (later I will add 1.5''-2,5''lift) is this going to affect fuel consumption and the onroad performance? does it need re-gearing or any other modification?
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
Ok help me understand this.. The Rubican has the same stock size tires as the first model yet, they are slightly taller, slightly wider. 😳 So, the Rubican does NOT have the same stock size tires as the first model as stated......... yea?
Good video. I have 33s on 17" wheels on my 2016 Sahara JK. All I have is a teraflex leveling 1.5" leveling kit. It rides really well and I do not off-road much if at all (mall crawler). Can I go up to 35s without any more modifications?
I have a 2017 Rubicon with a 2.5 inch lift. Running -30mm offset wheels and 35" BFG KO2's. I also have Poison Spider aluminium fenders. At full articulation with the steering turned fully to the drivers side, the passenger tire rubs on the Artec inner fender. But that's the only place I have any issues. I want to remove the rear sway bar to see how much more flex I can get. We want to keep the Jeep as low as possible, as we are both getting too old to have to get in and out of a Jeep that is so high off the ground we can't get our leg up that high anymore. I am curious if you changed out the fenders if the 35s would work. You definitely would need spacers or negative offset wheels. But you might be able to make it work. Depends on how much you flex the suspension.
Hello Rob. I have a 2020 jeep gladiator and I don't go off road it's my daily commute. I want to upgradey tires to go a little wide but having thesame 75% of as the factory tire. I like the way my jeep rides and I don't want ro change that. What tire and wheel can you advice me to go with
What's the largest size that fits the 2020 Wrangler Rubicon Recon 2 door without any modification or suspension lift? Still allowing enough articulation clearance and wheel turn without rubbing? thanks
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 !
Do I need a track widening on my JL Sport if I upgrade to 285/70r17? In some forum I read that you need a 60mm track widening if you put those tires on the stock rim.
Been planning to upgrade my jeep rubicon from stock to 315 70r17 without any mods. I know it fits but searching it says that i need to replace brake stopper or can make it uncomfortable. Thanks

Keep in mind. Every brands tire sizes are different than each brand. For example, BfG tires run small, nittos run true to size, etc.
Great point! It would be impossible to cover every single specific tire, but we hope this is a great starting point to pick out a tire size.
Only way you can run 35's with no lift is not never take it any where that you need anywhere close to full flex. They will 100% rub

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.
I thinking about 33 MTs. Just need them to perform well in snow and not overly loud on the payment.
The best review I’ve seen for this comparison!!! Thank you!
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
TJ 33’s 4.56 gears 4.0 manual. Great overall. I am not a rock beater tho.
Dude nailed content within the intro others couldn explain in whole videos :) love it !
We are here to help! thanks for the comment.
Im useing Ko 315/16 on my Sport 6 speed, great on the hiway but you can forget about ever useing 6th gear, with 2.53 gears Ill be going to a 33 next
Can you make video on different size of wheels as well how much difference they are with their sizes ? Thanks
I have a 21 Gladiator with 38 Milestar and 17 Dirt Life road kills im downsizing to 35 on 20s.
I like the 40s out of all of them
Thanks for the video. If I may ask could you in an upcoming video talk about portal axels?
Thanks again, 👏👏🙂🙂
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.
What do you think about 18" rims
Who does that work for the average person? Where do you usually take your jeep for this change?
I have a 20 Prius. How big can I go without cutting fenders and re-gearing?
I did 20 inch rims with 33 mud graps, I'm thinking about doing a 2" lift with 35 mud graps next
Nice!
Thanks for the video. Can we use larger than 17" wheels?
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.
I wonder where you got the idea for this video??? Awesome content, Godspeed!
32”s are now all the rage - good terrain, no lift needed and way cheaper than 33’s and 35s.
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?
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
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
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
How would these tire affect the engine and the gas mileage?
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!
Corner to corner. Left front to right rear and vice versa
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.
Aren't you forgetting something? Anything above stock will alter the speedometer which will require a new speed gear to keep the speedometer reading correct. Great video, very informative.
Great point!
It can be recalibrated electronically. No gear required.
@Jeff Wish Thank you. Your response is appreciated.
All you need to do is adjust you computer for the new tire size. I put 35s on and used a procal chip to make the changes
Great video! I have a question, if I put the 35' on my stock Rubicon (later I will add 1.5''-2,5''lift) is this going to affect fuel consumption and the onroad performance? does it need re-gearing or any other modification?
Would it be worth it putting 40s of you don't go off road. Have 40s just for the looks?
Your missing two of the best! 38x12.50R17 Nitto Ridge Grappler and 38x13.50r17 Trail Grappler🤘🏼
Trying to keep it to the common sizes, but the 38” nittos are great tires.
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
Rob, great video! Rob, what bumper does the 2 door gray rubicon have on it?
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.
Ok help me understand this.. The Rubican has the same stock size tires as the first model yet, they are slightly taller, slightly wider. 😳
So, the Rubican does NOT have the same stock size tires as the first model as stated......... yea?
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?
So, no 285's on a stock Saraha then without some modification of other things?
What kind of bumper is on the Jeep with the 37s
What winch bumper is that on the front of the Blue Wrangler on 40's...??
Hey!!! Second from the right. What rim is that with the snazzberry trim? Link please :)
So a 2014 Rubicon with a 4” lift can handle 37s without needing to change anything else?
31 is better for my YJ, not much loss of torque, I took off the 35"
It came with..Too top heavy..
How about a little more info on wheel offset?
Good video.
I have 33s on 17" wheels on my 2016 Sahara JK. All I have is a teraflex leveling 1.5" leveling kit. It rides really well and I do not off-road much if at all (mall crawler). Can I go up to 35s without any more modifications?
I have 33’s on my 2008 Sahara Unlimited, but with 35’s there wasn’t room and would have too much tire rub.
I run 35x12.5 on my '13 wrangler. With a 3" teraflex lift. You need a lift to run 35s properly.
@@KwanzaaBot1966 Correct. Mine is still stock.
I have a 2017 Rubicon with a 2.5 inch lift.
Running -30mm offset wheels and 35" BFG KO2's. I also have Poison Spider aluminium fenders. At full articulation with the steering turned fully to the drivers side, the passenger tire rubs on the Artec inner fender. But that's the only place I have any issues.
I want to remove the rear sway bar to see how much more flex I can get.
We want to keep the Jeep as low as possible, as we are both getting too old to have to get in and out of a Jeep that is so high off the ground we can't get our leg up that high anymore.
I am curious if you changed out the fenders if the 35s would work. You definitely would need spacers or negative offset wheels.
But you might be able to make it work.
Depends on how much you flex the suspension.
You will need to regear too.
38s on a 18" wheel is the best overall combo.
Nope, 17’s have far more wheel and tire options. Less weight.
Hello Rob. I have a 2020 jeep gladiator and I don't go off road it's my daily commute. I want to upgradey tires to go a little wide but having thesame 75% of as the factory tire. I like the way my jeep rides and I don't want ro change that. What tire and wheel can you advice me to go with
So I can fit rubicon tires on my stock lifted Sahara without rubbing
I need to see more of that 2 door with 37s and square headlights !!!
Will 275/70/r18 KO3’s fit on my stock 2024 Sahara?
What's the largest size that fits the 2020 Wrangler Rubicon Recon 2 door without any modification or suspension lift? Still allowing enough articulation clearance and wheel turn without rubbing? thanks
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 !
Do I need a track widening on my JL Sport if I upgrade to 285/70r17? In some forum I read that you need a 60mm track widening if you put those tires on the stock rim.
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?
I just bought a 2022 Wrangler Willys Ecodiesel. It has 32 inch tires. Can I put 37s on it with a 2 inch mopar lift?
What about for a Grand Cherokee Trailhawk 2018?
I wish they were all non rubicons because they already have higher fenders
Can you send a link to the 37in tires rims. Can I purchase those rims on your website?
Thanks
Been planning to upgrade my jeep rubicon from stock to 315 70r17 without any mods. I know it fits but searching it says that i need to replace brake stopper or can make it uncomfortable. Thanks
