I have a 99 keep Cherokee xj with a 3 inch lift and new skyjacker shocks. Ik 31's are the max you can fit without fender cutting, so I'm wondering if I can fit 12.50 or if I have to get 10.50 I'll take any suggestion on what to use I.e. wheel spacers. Thanks

 

My 99 is 3" on 32 11.50,but then again the fenders are getting trimmed

 

32x11.5's they work with 3-3.5".
I could do 33x12.5's I think, but would rub on articulation.

 

Both sizes will require the "Proper size of wheel" not a stock one for a 10.5" or a 12.5" tire you will need an 8" wide rim with 3.75-4" of BS on the wheel. Wheels are cheap for steel ones starting at $40 or so.


With a 31 to a 35" tire you need to trim the fenders to get full flex from your XJ or bump stop it to stop the travel. My 99 with a 3" lift was trimmed with 31x10:50's and it still rubbed a little flares removed so I trimmed a little more and went to 33x12:50x15"s.


The proper wheel is a key factor in any tire upgrade remember they have to be aired down for off road use.
