I always run winter tires from December to April but even so, my Contis are toast at 28k (43000 km). I bet that no more than 20000 miles went on the Contis. Actually the fronts are still OK but since they are five years old Im going to ditch them anyway. Im in for new tires in the spring. Ive heard that the GoodYears are good and so are the Pirellis.
