I have personally spoken with several Smart owners from the ClubSmart Canada of Montreal during our entourage to Cooperstown, NY. They adamantly stated that with good snow tires, the Smart has excellent traction on Wintry roads. I plan to put on a set of Hakkapaletta's for our Upstate NY Winter, most likely all four tires. That means another set of *Winter, steel wheels* to change out in the late Fall and early Spring with the WR's for the Spring and Summer driving. You can't tell I like Nokians, can you? Used them for the last 15 years....they're the best, IMHO.
