They are expensive, though. Also you have to consider that a harder compound will last longer, but does mean that they will not grip as well. I personally prefer a tire that lasts ~40-50k and gives me good grip. Not to say that the AT2's won't perform well, because the first versions (LTX A/T's) wore very well, but the traction suffered, especially in the snow. They wear like a rock, but grip like one, too. (IMO).
I much preferred the Bridgestone REVO's for road performance, wear and off-road performance. They last about 40-50k miles and cost about 20% less than the Michelins.
I'm not trying to knock Michelin, because I do like some of their products like the Michelin Pilot Sport series tires and their motorcycle tires, the Pilot Powers. I just think their truck tires are overpriced for what they have to offer.
