These tires run for a long time, 60-80 thousand, as it seemed to me. After each season, the spikes decrease, but where without it. I am not a fan of laying on the limit in the winter turn, and therefore I did not test rubber at critical moments, but in normal driving everything is buzzing. I can really recommend her to a friend. In a word, a tire from the world's leading manufacturer, who does not need to consult with anyone what pattern to make, or what studs to insert, is a good tire.
