How To Choose Tires For Your Jeep Wrangler JL - 31 vs 33 vs 35 vs 37 vs 40

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'

37 is where it’s at for both looks and capability

[patan]

37if you wanna break those axles. I think 35s are the best overall for everything unless you are heavily modding

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.

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

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 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.

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

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.

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.

[bobvedder]

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.

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.

We bought a 2022 jlu with the recon package... 35" tires and 4:56 gears from the factory

[TheHitSquadOffroad]

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.🙂

Keep in mind. Every brands tire sizes are different than each brand. For example, BfG tires run small, nittos run true to size, etc.

[dinocarozza]

Upgrading your gears may be necessary depending on tire size.

Am I the only one happy with 32s? Good fuel economy and I am doing 99.9% of what other jeeps doo

[J.brashear]

I snapped a drive shaft with 35s. Good luck going anything bigger than 35s without shelling out upgraded component

[_donjose]

Just bought 35s Mickey Thomson AT for my 2 door Jeep Wrangler, with a teraflex 2.5” lift so stoked to put them on 😂😭🔥🥵🤘🏼

Digging the white wheels. Looks like I remember the 80s.
