I've had snow tires (and all seasons) do great the first year and terrible the second year. Just that little bit of lost tread in a given year can completely change the tire. Heck, on my wife's MDX, the Goodyears (all season) were great last winter and fair at best this winter. Same car, same tire, except with another 8K worn off the tire and damn it is terrible. Or maybe the snow we are getting this year is different - it does feel colder after all
