not sure on the tire size yet, I was think of running 255/60 on the rear, I read somewhere to run 245/45 on the front and 255/50 on the rear. I have some 15x8-3/4 centerlines on there now with 4 3/4 backspacing but they rub some, so Im thinking I dont need no more than 3 3/4 out. guess ill go with the 8" thinking the tire will be to wide with 9.5's
