As Mr.C said 32" are fine and I don't think there is any brand in that size that will cause you a problem. Another member here just put on 33" X 11.50" BFG KM3's which is a LT tire with no problems. I just ran into my cousin Sunday which jumped from Can Am to the 1500 XD. He put on 35" tires and doesn't have a problem unless he takes it off road. He thinks he's going to solve the issue by moving the front shock mounting point and jacking with the preload...........I think he will learn he is wrong.
