What rig you gonna toss them under? I've got 33-10.5/15 BFG AT's on my XJ & trying to sell them to my friend so he can run them on his YJ. We swapped them over to his YJ the other day.
He had stock GC rims with 31/10.5/16 tire/rim combo. He'd rub the fronts on the leaf springs when at full turn.
My rims have 3.75" back spacing & when we tossed them on his YJ he didn't rub at all. The size, width& backspacing looked and worked really good with 3.5" of suspension lift. Hope that helps, he didn't send me any pictures of how it looks. It was midnight by the time we finished swapping them over.
