32 inch tire = what rim size?

I have a 1990 wrangler (it sits stock right now) and im trying to figure out what rim size i need if i get 32x11.5 tires. i also have no clue on wat backspacing is and how much i need. im looking at BFG All Terrains T/A KO(what ever that is) and it will be on a 3in lift if that helps. thnx

I wouldn't push that much, the rear axle won't last long. 31's is the max, and they fit on the stock 15x8 rims.

All about that unibody life.

^^ opinions vary... not sayinghte 35 is strong by no means but I abuse mine regularly with 33 TSL BIAs swampers, so cantsee 31 giving you much grief....

and ya for onlya 11.5 widetire use a 15x8 with about 3.5" of Backspacing

Agreed 15x8 with 3.5 - 3.75" backspacing. You might get away with a 7" rim with 11.50 tires, especially BFG AT's with that sweet rim protector.

street and general trail driving on 32s the rear will be fine. at that size a 15x8 is fine. most dont give options on backspacing and its not a huge conscern. ive put together a similar combination and it was too tall. id stick with a 2"-2.5."

I ran 33x12.5s on my stock 3.55 geared D35 for years, without a problem, so I'd have to disagree with this. They were on 15x8 rims with 3.75 backspacing (if I remember right).

16x8s are a good choice too. I have them on my JK with 4.10 rears!

The size of the wheel doesn't have anything to do with the gearing, it's the size of the tire on the wheel.....but I'll assume you're running 32's (no I didn't check your profile).

I ran 32X11.50's on the stock rims and then went to a 15X8" rim when I went to a 33X12.50 tire.

The stock rims rubbed a bit at full lock. I agree with a 15X8 with 4" or 3/75" of backspacing if you're already buying new rims though.

Go with 4" of BS if you want to stay with a 11.5" wide tire, but go to a 3.75" BS if you want to maybe run a 12.50 in the future. I run my 33X12.50 on a 4" BS and it still rubs a bit at full lock only.

Good sight to learn about wheel specs
https://www.rsracing.com/tech-wheel.html

And i run 33x12.5's on 15x8 rims. Dont remember what backspacing i have but do remember it is less than 3.75" which keeps it from rubbing but stuck out past the stock flares quiet a bit
