Shop Jeep Tires - www.quadratec.com/categories/...
The best size tires for your Jeep Wrangler will depend on a number of factors. Things like how you drive your Jeep and what types of terrain you'll be tackling will all come into play in your decision when shopping for larger tires. In this video, Rob will go over the benefits and things to consider about tire sizes ranging from 31" all the way up to 40" for your Jeep Wrangler JL or Jeep Gladiator JT. Learn about how tires are measured and how to read both metric and standard tire sizes. Then check out what each size tire looks like on a Wrangler and what goes into fitting each of those specific size tires on your Jeep, including new wheels and suspension modifications, and when it's time to consider other upgrades like re-gearing your axles or maybe upgrading them altogether.

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'
My thoughts exactly!
Agreed. 37s may be overkill for what I intend to use my Jeep for.
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.
Great job examples for new people to Jeepers 😎👍
From my experience with JTs I think the sweet spot is 37 & a 3.5 lift. I’m running 39s & 4.5 lift and it’s a little sweeter.🙂
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
Just bought 35s Mickey Thomson AT for my 2 door Jeep Wrangler, with a teraflex 2.5” lift so stoked to put them on 😂😭🔥🥵🤘🏼
The best review I’ve seen for this comparison!!! Thank you!
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 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
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.
We bought a 2022 jlu with the recon package... 35" tires and 4:56 gears from the factory
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.
37if you wanna break those axles. I think 35s are the best overall for everything unless you are heavily modding
Thanks for the video. If I may ask could you in an upcoming video talk about portal axels? Thanks again, 👏👏🙂🙂
37 is where it’s at for both looks and capability
No 38s is better
@@tahoecamper5078 38s yea I’m tryna put some on mine
Me too
That’s overkill in my opinion …. and you have to re-gear…
@@hellaacapella 2020 gladiator towmax. 2.5 lift 37” tires 25k miles. No regear.
Just bought my 1st Jeep YJ in NJ, drove it straight to Tx. 💪❤️🇵🇷🔥💯
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!
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 🎉😂
@@SlumpTia 2019 I think. That soft top fit on my wife's 2020, but it was probably a year older.
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.
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.
Am I the only one happy with 32s? Good fuel economy and I am doing 99.9% of what other jeeps doo
Never felt the need for going bigger than my stock tires on my 2021 Rubicon.
Can't all be winners lol, jk
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
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
Thanks. Very informative
Very informative, thanks!
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.
I snapped a drive shaft with 35s. Good luck going anything bigger than 35s without shelling out upgraded component
I wonder where you got the idea for this video??? Awesome content, Godspeed!
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….👍👍
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
2021 Rubi w da 33s LT285/70R17 doin just fine.
I chose 35 inch BFG KO2s with a 2 inch mopar lift. I dont have to regear my diffs and the gladiator rubicon works well for me.
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
Rob, great video! Rob, what bumper does the 2 door gray rubicon have on it?
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
We have 2 JKs on 35" BFG KM3, I would go for 33" next time. The big tires make the Jeep slower, more thirsty and handle worse.
Did you re gear it? That would be like night and day.
You have to regear for bigger tires.
@@singletrackmarc819 Still will not change the bad brakes and handling. It might accelerate better, yes.
I run 35s with 410 on my rubicon no issues
I have 35s on my tj either 5.13s and it has more get up then it did with factory tires and gears
Digging the white wheels. Looks like I remember the 80s.
Upgrading your gears may be necessary depending on tire size.
Yes, we agree 100%
@@Quadratect what size should you regear? have heard 33s and below you don't, 37s and up you do, but 35s seem to be a Grey area.
I'm at 40 on a jt rubi. Stock gears with a tazer mini getting 15mpg. I've seen 8th gear here and there lol
This is just the video I have been looking for. Thanks for advice 🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧👍👍👍
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.
great video you helped me undertstand
Glad it helped!
Great video!
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, what is the bumper type on the maroon Rubicon? Really like that style but cannot read the maker of it other than Quadratec on the integrated winch. Thanks!
Very informative.
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.
One does not acquire a Jeep for its gas mileage.
@@Koulnistwo maybe, but not one 💯
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
TJ 33’s 4.56 gears 4.0 manual. Great overall. I am not a rock beater tho.
So, no 285's on a stock Saraha then without some modification of other things?
Can i fit 285 tires on stock sport model ? Also should i download Jscan to adjust the gear transmission to the new tire ? ( im using now 245)
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
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
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?
What do you think about 18" rims
Rob..what brand/model of round lights that sit on the front bumper @ 09:31 and 09:52 ? Maybe Baja LP9's can you give details THX
I am going with a 20 inch rim whats the biggest 20 inch tire I can use
That green rubicon with the khaki top looks soooooooo good! I’ve never seen that before
I want to know more about that green Rubicon center caps
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.
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 like the 40s out of all of them
I need to see more of that 2 door with 37s and square headlights !!!
Dude nailed content within the intro others couldn explain in whole videos :) love it !
We are here to help! thanks for the comment.
I'm looking at 2021 gladiator Mojave I can run 35s o 36s ?? Do I need some type of suspension for it? Lift kit o spacers?? Thanks..
What rim is that on the red jeep? Do you sell these wheels and tires? I like how it matches.
What front bumper do you have on the gray Rubicon with the 33" tires. The first (leftmost) Rubicon.
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
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’s a good setup for a Mojave gladiator. It’s stock with 33’s on it currently
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?
Hey!!! Second from the right. What rim is that with the snazzberry trim? Link please :)
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.
I have a 21 Gladiator with 38 Milestar and 17 Dirt Life road kills im downsizing to 35 on 20s.
I never saw a green Rubicon with a tan soft-top and a white decal. Awesome set up. Do you know if this is a modified configuration? or a standard from a dealership? Would love to learn more
its a $900 option to have tan color top.
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
Can you send a link to the 37in tires rims. Can I purchase those rims on your website? Thanks
What fender flares are on the blue JK with the 40s?
What are those blue rims on the 40? Love ‘em!
12:23 cool shot bro 😎
I have 20×11 with -2.5 offset Wheels can I run 35 or 37 on stock JT sport with country rough 3.5 lift ?! Without regear ????
What kind of bumper is on the Jeep with the 37s
I have a 20 Prius. How big can I go without cutting fenders and re-gearing?
👰 you can try use .. giant tires dump truck
What about for a Grand Cherokee Trailhawk 2018?
What is the name of the wheel the 37” tires are wrapped around? It’s pretty close to what I’ve been looking for
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
Who does that work for the average person? Where do you usually take your jeep for this change?
Any one on how the Dana 44 will hold up? If you realy take it hard core, it might fall appart. Road warrior, limitless
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.
I did 20 inch rims with 33 mud graps, I'm thinking about doing a 2" lift with 35 mud graps next
Nice!
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.
Would it be worth it putting 40s of you don't go off road. Have 40s just for the looks?
So I can fit rubicon tires on my stock lifted Sahara without rubbing
33’s for me,
So a 2014 Rubicon with a 4” lift can handle 37s without needing to change anything else?
How about a little more info on wheel offset?
Rob, Would a set of 37s on 2021 gladiator with 5” lift require gears change/upgrades?
When you are considering adding larger tires, you should consider the rotational mass and weight that you are adding. Stronger axles like those on the Rubicon might be needed to help mitigate that issue. Gearing is the other consideration. Here is a link to an article that discusses that very thing with a great chart, as well. www.quadratec.com/c/reference/best-gear-ratio-when-adding-larger-tires?Comments
What’s the bumper on the sting grey wrangler rubicon?
Great information. I’d like to see something on a Rubicon (JT) running 35’s and clearance during full articulation.
If you are looking to actually wheel your JL with 35's you will 100% need to lift it, if you do not want any rubbing. I have 35's on the mopar 2in lift on my JL Rubicon and they just clear at full flex. My buddy tried to run 35's on his JT Gladiator and they rub alot at full flex.
@@JJ-yy4yy good to know. Mods that aren’t fully usable are meaningless to me. Thanks.
A JT with 35s is going to need atleast 2.5 lift to have descent articulation.
@@TheHitSquadOffroad if it can’t fully articulate I see no point in doing it.
@@crabblike full articulation can be a bit tricky from what I've learned so far. For instance, I have a 4.5 Rock Krawler Pro-X lift on my JT with 39s. With my stock Overland fenders it was limiting my articulation, but I still had alot of articulation. I finally switched out to higher clearance fenders and gained more inches in articulation, but my flex is still limited by the fenders in the front. Also depending on how your lift is setup, your shock length and your bumpstops will play a major part in your articulation. When I go to long arm in the front I will get suspension fine tuned to where everything lines up properly and I'm getting the most articulation possible without over extending anything.
