uh guys, he isn't asking whether he should run 33's or 35's....
And in answer to the original Q, In NORMAL driving these trucks will fit a 35 in the rear without trimming. they almost clear in the front, but a 1" body lift should make it go. body lifts have a weird way of doing that...
although, the first time you get that thing flexing, expect those tires to make contact. which 33's would do with stock suspension in the same scenario.
