The first winter and about 15,000 miles with these tires were actually pretty good. However, the second year and an additional 20,000 miles have proven to be a bit too much for them. The tires are constantly losing traction in all kinds of snow/ice and the snow remains packed into the treads despite efforts to keep them clear. I pretty much have to stay in 4x4 mode all the time in order to maintain proper traction and control. The tires are rotated every 5,000 to 6,000 miles. No complaints during dry conditions. Not sure if they are going to last the warranty miles.
