Here are some photos of stuffed 31s, 32s, and 33s on my Raider.

31"x10.5" BFG All Terrains on 15"x8" rims with 4" back space:


32"x11.5" BFG Muds on 15"x8" rims with 3.25" backspace:


33"x12.5" Dakota A/T's on 15x8 and 15x10 (F/R) with 4" back space:




I have not used the factory rims with more then 235's, but have found that 31's probably wouldn't rub. With my aftermarket wheels, the 31's made no contact anywhere with all knids of flexy conditions. The 32's self-clearanced the front bumper ends, but did not rub anywhere else. The 33's do not rub in the rear and only mildly in the front. I'm planning on the 2" body lift though, so I am not worried about the current contact. <img src="/forums/images/graemlins/kewl.gif" alt="" />
