second season on these tires, when they were brand new I was wondering, but into the second season they are exceeding my expectations in all areas of winter driving. They are also an excellent highway tire on very cold roads. When we had the goodyear rsa's on the car, for winter driving, we thought there was something wrong with the car. With the Michelen's, winter is just as enjoyable as summer. So far tread wear appears to be excellent.
