205/60R15 front 255/60R15 rear
Thats funny because I was just talking to a buddy of mine about this same thing. I was thinking of using a 6" wide rim. My buddy is using 15 x 7 up front and 15 x 8 in the back. But he has them on his Shitvelle. I told him I thought the 15 x 7 were to big and I wanted to run a rim size of 15 x 6 with a 205 tire. On my rear I'm running 245's and thought about trying 255's. I'm glad you posted this. Maybe I'll try a 250's.
