I bought my set from Tire Rack in spring of 2011 when they first came out. I was planning on replacing my second used set of summer PS2s then, but I was able to stretch out the PS2 use until winter came. So I didn't need to replace my summer tires until this past spring.
Anyone one knows the warranty on these tires? It still has 80 percent treads left.
TireRack.com has details on your warranty
However it will be very difficult to prove to them that the tires have less grip than they should. there are too many variables and your subjective feedback will likely not be sufficient. you could maybe appeal to Michelin customer service to try to get you a replacement set.
