2003 S500 4MATIC
These are the 2 top-rated UHPAS tires on tirerack.com for my size (225/55-17). I have a set of snow tires so winter performance is not that important. The Pilot Sports get slightly better ratings but the noise comfort is worse and they are more expensive even with the $60 rebate deal that just started. Also, there are not many reviews of the Pilot Sports so the ratings are less reliable. Opinions on each?
