I have a set of Michelin alpin winters - went with same size as summers on different rims. I live in Ontario, Canada. Mainly for cold weather grip, not as much about snow bite. I dont drive it in snow, end up snow plowing and getting stuck. Mostly for driving on cold crisp clear days. Works great, last winter sucked in Feb, but I got to drive it probably 3 months more than I would have without the winter set.
