I recently got a '04 Chevy HD 4x4 and love it. Problem is the wheel and tire package I'm dealt with is awful. 245's??? I'm just wantin to get some varying opinions on the maximum wheel and tire combo with only a t-bar crank and no lift. I would love to get some 305's on 16x10's. Am I dreamin or is the best I can get 285's on like 16x8's??
