I am starting on the second season with these tires. My car is stored most of the cold months. I am happy with how these tire hold up to rough roads and very aggressive driving I do. These are very low profile tires in a staggered formation on my AMG- 245/35/19 front and 275/30/19 rear. The quietness and traction they provide is outstanding. I have been in a few hard rain storms and maintained 75-80mph to test the traction, hydroplaning, and they felt very capable. The Michelin's feel very confident at high end speeds. I believe the warranty on these is 30,000 miles. I don't expect them to last that long with my driving style, though if i were to get 20,000 on them, I'd be happy. I will most likely try these tires on a track day in the future. They are worth the money!
