I was wondering if anyone had put a larger tire on the interior holder. There is room front, back, and up, but not down. I would like to mount a 33x12.5 tire in there. If there is no way to do this, how close in size should the spare be? Thanks. Brian 84k5, 4"Skyjacker kit,33x12.5 goodyear mtr, and 15x10 bajas ordered!
