had to replace the stock continentals (pieces of chit) after i ran over something and didnt want the same crap for replacements. Bought Michelin mxv4 Primacy in 18" and what nice tires!!! Very smooth, very good handling, and a great ride. The car lunges off the line due to less rolling resistance, and handles like on rails. if the warranty holds up these will be a great set of tires!!
