I have two xj's, one with a 4.5 all spring lift, the other with a 3 inch all spring and 2 inch shackles and pucks. Both run 32's. The 32X11.50X15 was hard to find and a bit more expensive than 33's but they don't hit except for very severe wheeling. The other, with the 4.5 lift has 265/75/16 bfg mt's, about 32 inches, on factory type wheels (YJ?) they will hit in the rear with severe duty wheeling.

2001 XJ Sport, 4.5 Rusty's lift, 32x1150x15 Hankook Dynapro MT's. 4.0, aw4, 231, 8.25 rear with power trax locker.
