Only had for around 1K miles but thought I would review anyway. Absolutely OUTSTANDING on snow and ice, I bought these to replace my Goodyear MTR's right before we got 12 of snow, there is no comparison. On packed, snowy roads, it feels SOLID.
As far as off-road tires go, these are definitely a winner. Not as good in mud as the Goodyear MTR's but still very good, and MUCH quieter as well. I don't even notice them on the highway, WAY quieter than the MTR's, but that may change once they have a few thousand miles on them (it usually does).
Outstanding wet traction as well. I haven't had these for long, but if you asked me now if I would buy them again, the answer would be YES.
