I really liked the rubber. Quiet, holds the road, there are no problems on the ice, rowing in the snow. I skated 10 thousand per season, on the Duster, mostly city-highway. All spikes in place, minimal wear 11/11/21 As a result, skated 3 seasons (about 30 thousand km.). Only 2 spikes fell off 4 wheels. The rubber would have left at least the same amount if I had not changed the car.
