Now while I haven't had these tires on for more than 50 miles yet, and it hasn't snowed here since I mounted them, I can say that they have noticeably more comfortable ride than the Michelin Pilot Sport 4S tires did in cold weather. Traction seems better (as it should be) without giving up much of the instant steering response of the summer tires. Time will tell how well they do in deep snow, but even though I'm well into the snow belt the local municipalities and state DOT do a great job of keeping the heavy stuff plowed off the road. So what's most important to me is handling the slick/wet/packed snow surface as well as the cold/dry/salt dust covered roads that prevail between snow events. The reviews I've read say that the Sottozero 3 is designed for what I expect to encounter.
I'm curious if anyone else has tried this tire?
