Just changed all four all season tires. I only use them in late spring, all summer and early fall. I switch to dedicated winter tires for safety reasons even though my vehicle is a 4 MATIC. The tires are very quiet and smooth on the road. I am extremely happy with the performance. It is too soon to comment on tread wear. I intentionally rated one star for snow handling and tread wear.
This tire has horrible treadwear. It is supposedly rated for 45,000 miles and this is my third set of these tires which barely make it to 20,000 miles. It is my wife's car and she does not drive aggressively or brakes hard. This car gets normal everyday use. As a matter of fact, it probably gets more (less-wearing) highway miles than most cars, so these tires should really last.... ha! I am going to try Goodyear Eagle F1 tires next, as I am tired of wasting my money on these Michelin tires.
