One thing that hasn't been mentioned is that as far as I know, all high performance tire manufacturers say don't use them at temps below 32 degrees. So it not just about snow. I have the Michelin Pilot Sports A/S Plus Zero Pressure tires on my Vette and when you consider the slightly lesser performance in summer with the greater performance in winter, I believe that overall performance for year round is actually better than using a summer tire year round. The Vette is actually dangerous with summer tires in winter and I suspect my 135i is the same.
