These are the best set of tires that I've owned. I've driven these tires in almost all conditions including many miles in Colorado mountains during winter. The tires always performed well and I've been impressed with their traction in snowy and icy conditions which is comparable to snow tires. I originally bought these tires in 2006 and just replaced them after 80,000 miles. The tires still have over 5/32 tread left and I think they would probably go another 50,000. I just bought a set of the M/S2 and expect to get the same if not better results from these tires.
