How wide are the factory wheels on my jeep?

A pic for refrence

[89eliminator]

most likely 15x7

[88JeepManche]

so my next question is could i put a 10.50 or an 11.50 tire on them?

I remember Eagle saying you should only go about 3 to 3.5 inches more.10.5 I think your good. 11.5 I think you rub the LCA on tight turns.

That info should be stamped on the inside of the wheel on one of the spokes.

i just ordered 33x10.5's on 15x8's. i think that you should get a wider rim if you want to run wider tires.

CW ran some bigger tires on those rims I believe, PM him. I think you are ok w/10.5s but your max'd out at that point.

I'm running Khumo 31x10.5 on those exact rims on a stock XJ. Anything bigger and Id be going for a larger rim, these tires don't rub the CA's and flex well

Those 10-spoke "turbine" rims are 15x7. They're good for 10.50" inch wide tires. The usual rule of thumb is that tire width should not exceed rim width + 4". However, as you get into very large tires, with lots of sidewall height to allow for transitions, you can go wider.

 

However, do NOT run tires wider than 10.50 on those rims on an MJ. Even 10.50s will rub the lower control arms (in fact, even 30x9.50s will rub the lower control arms), but a worse problem is how close the sidewalls on the rear will be to the springs and the inner fenders. Running 31x10.50s on those rims, I had black rubber marks all over the inner wheel wells in the abck after every trip, and there's just a tiny bit of clearance to the leaf springs. An 11.50" tire will be another half inch closer to the fender, and will be probably making contact with the rear leaf springs. If you need tires wider than 10.50 you're better off using aftermarket rims with less backspacing.

What is the backspacing on factory rims?

[chicofuentes0224]

I THINK 5"

Thats what i needed to know. I just wanted to upgrade from the 9.50's i am using now to a 10.50.
