I love my Dayton Timberline MT 235/85r16 tires. You will need to trim the bumper (not just that extra little dam, but into the bumper itself), and heat gun mold the well liner before it can go in reverse while turning. Mine still needs more, so I can turn w/o making good-awful noises. I had to trail trim the rear liner on the rear doors (open your back door and see that flange of a liner - it goes!) Wider tires at 32" would need wheel spacers. To see what they look like, see here
http://www.lostjeeps.com/forum/phpBB3/viewtopic.php?t=16043 mine is the Dk. Khaki Renegade with big, all black tires... Also, when they stuff, you will know it. I guess I could get a bigger bumpstop for the rear though...
Oh, the Timberlines rock! I just got back from mud today - great traction, and livingston last weekend - they were great on the rock. Wet pavement is good too, just road noise from the MT...
