if you don't mind cutting 33s will fit, at minimum you need a 1.25" BL and flat fenders. I ran my tj like that for a while than decided to cut more to gain a bit more clearance in front. the rear will clear a 33 if you pull out the inner plastic fenders.
35s- =D this was still while I was building it, haven't taken any new pictures yet.
flat fenders always gives you more room to go BIGGER tires.
