Now that I need 2 new tires, I may as well get 4 and be done with those crap Dunlops. Would like to try Bridgestone S-02, which I can get in a few days time. My concern is future availability, as I drive my cars in Europe and the US. Michelin is an OEM tire (and a good one from my experience with Viper), so it may be more readily available in the future... any thoughts? Dan
