I just had my tires changed, and decided on the Michelin Pilot Sports A/S Plus after much analysis of comments in various threads on this and the mbworld forums.

Used to have GoodYear F1 A/S, and never knew how noisy they were until I switched to the Michelins.

Could have been cheaper buying online but Costco is just 2 mins away, and the little extra for the convenience and additional after-sales service warranty made it an easy choice for me.
