Re: 15x10 rims on a 89 YJ????
I'm running 15x10 rims with my 35s, with 3 3/4 inch back spacing. Will also give you better tire clearence when turning. I made custom fender extensions for my 87 but a set of 6 1/2 inch Zenon flares will just cover the tread. I think 8 inch rims with a 12.50 tire suck the sidewalls in to much. Alot of people do it though. Just my opinion. Steve
