ok so i have a piza cutter (BFG 33x10.5x15 MT) and I was looking to get those AR 767s. I went to Town Fair Tire to get a quote on the wheels for a 15x8 and the guy there said that the rim I have now (stock 15x7) is too small as it is and was I sure that I didn't want to get the 15x10? is the 15x10 too big for my tire? I though 15x10 was for 12.5 wide tires? I mean if I can get it I probably will but I just want to make sure.
