I just purchased these tires about a month and a half ago, and Im in love with them. Ive never owned winter tires that preform so well. These studless tires worked even better than the studded tires I used last year. Just to give a little perspective; one night i was coming home from work and it was snowing pretty hard. The roads were covered with snow and as I started up one of the biggest hills in Spokane, I noticed numerous vehicles stopped in the middle of the road and also on the side of the road. They apparently did not have sufficient traction to make it up the hill. I found it sort of funny because (other than the snow on the road) there was no indication that the road was slick. I literally had not slipped the whole way there, or the whole way up the hill for that matter. I had perfect traction. Ive had no problems with them at all and I would definately consider these tires to be top of the line.
