I want to go as big as I can stock, without trimming (unless it's very minor) and I do wheel it if that changes anything.

My springs appear to be in good condition as it seems to ride higher than other stock cherokees. Should I measuse to see?

I know this is asked a lot, but I wanted to be sure under my specific circumstances.

Thanks

 

29 or 30 inches is about all you'll be able to fit. The 30" tires will require some trimming, but each XJ is a little different, so it's hard to say!! HTH!!

 

I put on a set of 30" pro comp mt's and did not have to do any trimming. I did some moderate off roading a few weeks ago and did not hear or see any signs of rubbing. 30" is going to be the largest you can fit.
