Overall this has been a great tire. I bought them following an accident resulting from poor traction OEM tires in a snowy environment and I have to say they have performed extremely well. My truck is heavy (8K), and has tons of torque. These tires never let go of the road and have worn suprisingly well considering I pull a 14K horse trailer with them. As it stands I think they will make it to the 45K range before I absolutely have to change them. I am down to 4/32 now with 33K on them now. They never even break loose on wet pavement which is something all diesel owners can appreciate. As for snow traction, they were pretty amazing. My wife was stranded on the highway in a snowstorm shortly after I bought them and I was able to get to her with almost no slipping. I also pulled 4 other trucks out on the way to her. Were I not finding myself spending more time off road now than on it, I would definately buy these tires again. They have been so good, in fact, that I have talked many of my relatives into getting them. Additionally this is the first set of tires I have bought from tirerack, and I expect I will continue to use this website for future tire purchases.
