Whenever I look at my xj (and ponder bigger wheels) I can't help but wonder if I could shift the rear axle back an inch or so remove the rear bumper wrap around I could run atleast 31 without much if any fender trimming. Any thoughts? Right now there is no lift but considering a 2.5 to 3" lift in the near future (with a lift same question only bigger tires, I know I would need to do many other mods but that is another issue.) The jeep is basically stock 98 130000 miles, ABS and a dana 35. This is a daily driver but I do go off road and getting adventurous.
