but if are you looking to get some new tires I would also check out Bridgestone Potenza S-03 Pole Position.

Most people seem to agree that the S-03s are one step ahead of the T1-S and the price is similar. The S-03s are about $10 less or so per tire right now.

For example: from tirerack.com S-03s 205/55WR15 $102

From treadepot.com Toyo T1-s 205/55R15 $ 119.00


I went with T1-S based on a friends recommendation who also had a M Coupe.
