Changed the wheels and tires for this set. I could not alter the offset on the previous 10.5" rears to keep the edge of the tire in synch with the fender edge. I can't stand when they stick out unless your a drag car. Anymore shaving from a C&C and the wheel safety was compromised. I am here to say the widest you can put on the back in 20 X 10 and 20 X 9 in the front.
