i did 3" body and 3" suspension for 33x12.50's and we still had to cut the shit outta my X. mudflaps (the ones you dont take off, dont konw what they're called) and to get the hell cut outta them, roughly 4" off the nerf bars had to come off too. I went w/ Truxus STS and i gotta say, this is one great tire. i'd recommend it to just about anyone that wants a/t. had it in sand and thick ass mud 2 days ago and they performed flawlessly. hope it helps
