7.5" wide. 12.50 on a 35 or 37" tire is 100% fine. If you don't want it pinched, a 285 section tire is available.

Thanks now I can look at tires. I'm going to get a rough country 2.5 inch lift. Wanted to use stock rims for now.

Most tire manufacturers will not rate a 12.50" or metric equivalent tire width on a 7.5" rim. Usually it is 8.0"-10.0".

That being said, there is probably hundreds if not thousands who do run it on a 7.5" width rim with no issue.

with no issue

I would rephrase this as no major issue.

Should anyone running 315s or 12.5s on 7.5s expect catastrophic failure? absolutely not

But, you can't just pinch in the sidewalls beyond mnfr recommendations for free. Either you have to run lower PSI to pass a chalk test, or you have to be okay with a thiner contact patch.

Run "normal" PSI and you're effectively over-inflated, and that's no good for tire wear. You'll need tires sooner.

Run chalk test PSI, and you're getting some extra sidewall flex. More flex at highway speeds means more heat, more heat means more wear, means you'll need more tires sooner.

I don't want to talk anyone out of 12.5s on 7.5s per se, but i do want everyone considering it to understand that there's no such thing as a free lunch. There is a trade-off. If you've considered the trade-off and decide to anyway, by all means go ahead.

Is this the same for a 2021 Willy’s? I’d like a little bigger that the 255/75/17 set up.

My brother has a 21 Willys and it has 20" rims.

Yes, all Willy's came with 7.5" regardless of year.

Thank you for that. Where can I find how big of a tire I can put in there without needing a new wheel?

I am currently running 37x12.50x17 KO2's on stock 7.5" wheels. Contrary to some comments, it can be done with a little modification to the plastic fender wells.

The stock Willys wheel has been 17". If he has 20's, he either swapped them out or the dealer / previous owner performed a swap. If it's a stock 20" wheel, it's more than likely the 20" from the High Altitude / Nighthawk (same as JL Sahara).

 

[Great Offender]

Confirming with him now once he replies to my text. I know he traveled multiple states to find the color he wanted. It's a 2021 and I have been in it so I know it does say "Willys" on the hood.

You are correct. He just confirmed 255/70/R17. Old age is getting the better of me.

Pretty sure all JT rims, minus the High Altitude ones, are 7.5" wide.

That tire and wheel bead looks like a can of biscuits ready to pop.
