This was my first experience with winter tires and I will never drive on all seasons through the cold months again! After a couple winters on the stock all seasons we bought these and my wife, who put most of the miles on the vehicle, is confident they prevented more than one accident. I drive the van on weekends so the tires have seen some aggressive driving in addition to the wife's conservative style. I've been very impressed with the ice traction, the main reason I wanted to try winter tires, but the snow traction is much better than all seasons but could be better. At the same time I also put a set of Nokian WR G2s on my 1999 Mazda Protege and actually found them to have better deep snow traction despite being on a much lighter vehicle that previously struggled with deep snow. However the Xi2 is noticeably better on ice. I'm now shopping for tires on our new '12 Honda Odyssey and wish the Xi3 tires were available because of their reported snow traction improvement. After nearly 27,000 winter miles (17,000 km) there was a lot of tread left. We put 3 winters on them and probably would have got another 2 with our typical mileage split as follows: Snow/Ice 40%, Wet City 10%, Dry City 40%, Highway 10%.
