I live in Northern Quebec, Canada, on icy mountain roads where the weather is a real knave (i.e. for the last two years the snow had covered our two floor house entirely). 2nd winter on these tires and I think we'll be able to keep them for another winter. So far, the best tires ever. Blizzak DM-V1 = Stability, excellent ice/wet and deep snow traction, no noise at all. Design for real Canadian winters !
