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.
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 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.
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.
The best review I’ve seen for this comparison!!! Thank you!
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.🙂
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
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 😂😭🔥🥵🤘🏼
We bought a 2022 jlu with the recon package... 35" tires and 4:56 gears from the factory
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.
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.
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'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.
Very informative, thanks!
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!
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
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
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 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.
Great video!
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
Thanks for the video. If I may ask could you in an upcoming video talk about portal axels?
Thanks again, 👏👏🙂🙂
Digging the white wheels. Looks like I remember the 80s.
great video you helped me undertstand
Glad it helped!
This is just the video I have been looking for. Thanks for advice 🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧👍👍👍
Thanks. Very informative
2021 Rubi w da 33s LT285/70R17 doin just fine.
37if you wanna break those axles. I think 35s are the best overall for everything unless you are heavily modding
I snapped a drive shaft with 35s. Good luck going anything bigger than 35s without shelling out upgraded component
Never felt the need for going bigger than my stock tires on my 2021 Rubicon.
Can't all be winners lol, jk
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.
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
I wonder where you got the idea for this video??? Awesome content, Godspeed!
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
Very informative.
Rob, great video! Rob, what bumper does the 2 door gray rubicon have on it?
Great Job. Love the new JL that had the old YJ grille.
Thanks 👍
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….👍👍
That green rubicon with the khaki top looks soooooooo good! I’ve never seen that before
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!
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.
Dude nailed content within the intro others couldn explain in whole videos :) love it !
We are here to help! thanks for the comment.
I want to know more about that green Rubicon center caps
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
TJ 33’s 4.56 gears 4.0 manual. Great overall. I am not a rock beater tho.
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
What do you think about 18" rims
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
💯
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
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)
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 need to see more of that 2 door with 37s and square headlights !!!
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 are those blue rims on the 40? Love ‘em!
I like the 40s out of all of them
What rim is that on the red jeep? Do you sell these wheels and tires? I like how it matches.
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.
What front bumper do you have on the gray Rubicon with the 33" tires. The first (leftmost) Rubicon.
Hey!!! Second from the right. What rim is that with the snazzberry trim? Link please :)
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
What’s a good setup for a Mojave gladiator. It’s stock with 33’s on it currently
Can you send a link to the 37in tires rims. Can I purchase those rims on your website?
Thanks
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 remember back in the day 35’s were the big dogs ish, now it’s as if they are like a 31” tire lol.
12:23 cool shot bro 😎
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
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'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 kind of bumper is on the Jeep with the 37s
What fender flares are on the blue JK with the 40s?
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.
How about a little more info on wheel offset?
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?
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.
What’s the bumper on the sting grey wrangler rubicon?
I have a 21 Gladiator with 38 Milestar and 17 Dirt Life road kills im downsizing to 35 on 20s.
What is the name of the wheel the 37” tires are wrapped around? It’s pretty close to what I’ve been looking for
👰 you can try use .. giant tires dump truck
What about for a Grand Cherokee Trailhawk 2018?
I have a 20 Prius. How big can I go without cutting fenders and re-gearing?
So, no 285's on a stock Saraha then without some modification of other things?
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 ????
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
Would it be worth it putting 40s of you don't go off road. Have 40s just for the looks?
What were the rims in the 37 inch?
I am going with a 20 inch rim whats the biggest 20 inch tire I can use
Do you think you need to regear or truss your axels for 37s on the gladiator?
Regear would be best for 37s. Most JTs in my group are going 4.88s with 37s. For those who are thinking of going bigger tires they are going to 5.13s with gas engines. Depending on the type of off-roading and your style of wheeling will highly determine if you need to truss your axles. I’m running 39s on my JT and my axles are stock. I wheel my JT, but I’m slow and steady. I will upgrade my axles in the future though. I’ve done practically all the trails in Big Bear, Ca and haven’t had any problems so far.
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.
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
So I can fit rubicon tires on my stock lifted Sahara without rubbing
What wheels are those on the 37s??
So a 2014 Rubicon with a 4” lift can handle 37s without needing to change anything else?
I have a 2021 JLU Sport with diesel engine. It came with all season 245 75 17 tires that I switched out first thing after leaving the dealer lot with 265 70 17 Goodyear A/T tires. I wish I would have gone to a 33 inch tire as I need a little more ground clearance. Will the 33 inch 285 70 17 Rubicon tire fit my Sport without rubbing? It is also 1/2 inch wider. I will go to a lift if needed but just need an inch or two more ground clearance for the trails that I run. If I go to the slightly higher Rubicon fender flares will that stop any rubbing due to tire height?
Did you ever find out? I have the same question too!
I did 20 inch rims with 33 mud graps, I'm thinking about doing a 2" lift with 35 mud graps next
Nice!
Are 33s doable on a base model JL?
Any one on how the Dana 44 will hold up? If you realy take it hard core, it might fall appart. Road warrior, limitless
