When I bought my S, the previous owner had 18x8 3/8 offset wheels on both front and rear. Tire size on both front and rear is 225/40R18. Not the most ideal setup I know. I talked to Jim at TireRack and he suggested the below set up, but noted the rears would be tight.

Front - 215/40R18
Rear - 245/35R18

Does anyone have this set up? If so, do the rears rub or stick out? Will the handling be better or worse than 225/40R18 all the way around?

thanks guys
