I've had mixed success with ice traction on my half ton pickups using AT tires. My current tires on two pickups are Hankook Dynapro ATMs, and they're not bad. Friend of mine swears by his Cooper AT3 4S, but another friends had a set of the original Cooper AT3 and said they were horrible. So, for those of you in the northern climates, what do you think is the best AT light truck tires for winter conditions, ice traction a priority, mostly on pavement but some off-road as well?
