Recommended Max Tire Size for stock WB TJ

Wildman1 · Nov 25, 2007

What size tire is the max for a stock WB TJ? I am hearing 37" but then I ahve seen some people running 39.5" tires on a stock WB TJ. It would be about the same as running 35" on a 81"WB CJ?? Don't know I am asking???

Edumicate me plezzze!!

I personally think 37's are the max. Only because thats what i think.

I don't understand the question, are you referring to what the stock axles will handle?

Ain't asking what tire size to run with what axle. I am asking what tire size to run with a stock WB TJ. You know 94" WB.

my wheelbase in my cj is stock 94" and i run 38.5's with zero problems. It actually feels more stable now then it did on 33's if that helps answer your question.

31x10.5 should be fine.

Thanks, it is nice to get an honest answer instead of all the BS. How much lift are you running? What axles and what width on the axles?

I think a more pertinent measurment would be how high your CG would end up compared to your WB. If you were cutting out sheet metal to fit larger tires with no net change to the lift, you could fit larger tires no prob.

Bishop's rig on 37s is fine for stability and I haven't heard any probs from Spenser's 38.5s. :awesomework:

I know he runs a 44 in the front---can't remember whats in the rear and I am pretty sure he is close to 62" wms-wms

Mike,
Thanks for that. So pretty much my Jeep too. Still bounching this around in my head as to what I want to do right now. I think I might be crazy but for what ever reason I have been toying with going to 39" tires. Should just stay with 35 or 36" tires but hey what the hell it could be fun.

Hell by the time you air the tires down to 4psi they'll be 36's anyway:awesomework:

42" Iroks. Hard to say with the amount of lift though since none of my spring/shackle mounts are in stock locations. I'm on stock 7 leaf waggy fronts in the rear and heavy duty CJ springs in the front both SOA. I do know I'm currently lower than I was on 37s with 2 inch cj lift springs SOA before the wheelbase stretch and spring outboard.
