I too would (do) stick to the stock size of 205/55. If your car is lowered you might get away with the 215/50 size but since they are a smig shorter, you'll have more gap between the top of the tire and the top of the fender well and that will be more pronounced on a stock ride height vehicle. Also on the 99's and later vehicles the fender liner was revised to take the slightly wider 215/50.
