I'll be replacing the Cooper AT2's on my truck next winter. Compared to the previous Toyo AT's, they have a better ride and better grip in the rain. Got caught in a surprise snow storm on a pass in Oregon (weather forecast = no snow) and they kept my truck and trailer (17K# combined) rolling up the hill without drama (and w/o chains). I was absolutely shocked by their performance.
I like them enough that I will be getting a new set of AT3's to replace them. I've had a lot of different tires on our RAM over the last 20 years but these are my favorites.
