Ok I have a 2011 Denali 3500 single wheel and am looking at some tires. I know this has probably been beat to death but I bought the truck and tires already worn so not sure how they are new. Basically I do mostly highway driving but I do some "offroad" because I race motocross, and haul a 40' fifth wheel. I want something that's semi quiet on the highway, good off road but not my major concern I just don't want to get stuck with my camper, last awhile, great in the rain. I live in south Georgia so snow don't care about. Right now I have Duratracs but they are pretty work. I was looking at Duratrac, Nitto Ridge Grappler, and Toyo open country AT2. From what I have read so far I probably will go with the Nitto but want your guys opinions. The only experience I have is LMM with Michelin LTX AT2 they seem good but would like more aggressive, and my work out Duratracs now.
