I ordered my car with the Michelin PSS's and bought another set of rims with Michelin Alpine's for the winter.

I've always had all season tires on past cars and never had trouble (although ultra-high performance all-seasons are awfully fun in the snow). However, all season tires don't perform as well as a dedicated summer / winter tire. With this car, I didn't want to compromise performance on dry pavement so I went with the PSS's. That, in turn, forced my hand into getting a second set of tires, as Michelin states that the PSS's should not be driven in prolonged temps below 40deg F.
