Since I bought these we have not had deep snow so I can not coment on there deep snow ability. They are very good in light snow and they have worn very well, still showing almost no wear after almost 10K miles. The negatioves about these tires are they significant noiser then the bridgstones that come with the car and you loose about 1.5 miles a gallon (36.8 with the factor Bridgestoe all- seasons vs 35.2 on the Altrimax snows), handlin g in the dry and wet is about the same, they are much, much better even in light snow slush and black ice. The MPG is not a bad trade off for the better winter ability of the tier. The noise was expected afteall it has a much more aggressive tread. I also take my dog to the park often and these tires are also much better on dirt roads, makes the car feel like it has 4 wheel drive, much better traction on dirt, no slipping or sliding.
