Not sure about the top marks for tread wear -- too new to be certain. The tires I had before were Michelin X-Ice 3 and they fell far short of reasonable expectations. My wife is delighted with the traction in rain and snow [just had a 6" dump -- no issues]. Tires are very quiet on the highway at almost any speed, Ride and handling are excellent and stopping power is very good. Very happy with this purchase.
