Asymmetric performance tread: A performance-focused tread pattern with strong outer-shoulder support helps deliver lateral grip, steering precision, and planted cornering.

Pilot Sport All Season 4 Customer Reviews
I'm satisfied
All said and Done, I dont recommend these tires for the sheer fact that I get 15% less range with these when compared with the Factory tires. It does not matter if you get a good deal on these since over the years you are spending more in Charging costs over the years. I drive a lot( 100+ miles per day) so I can clearly know the Range is lower. It does not matter its summer, spring or Winter.
I would absolutely love these tires if the tread life was commensurate with the advertised 45,000 miles but each of the 3 sets I have owned has only last about 27-30,000 miles. The good news is that America's Tires was easily able to get a rebate directly from Michelin before I even checked out of the store.
