My vote is for either the Toyo Open Country AT2's or the BF Goodrich all terrain KO2's. I have both on different trucks. The BFG's are on my old GMC k25 and the Toyo's are on my dually. I can't comment on the life span on the new BFG's but, the Toyo's are quite impressive. Toyo offers a 50,000 mile warranty on some of the AT2's and a 65,000 mile warranty on others. My dually is a big heavy truck with tons of torque. I already have about 25,000 miles on them and I have never rotated, checked the balance, or aligned the truck after the initial install. I think the fronts will last another 15,000 miles and the rears will last another 25,000 or maybe even another 30,000 miles. And that is just about all towing with no real maintenance on them. The Goodyear Dura tracks are also a good choice but, I have no personal experience with them.
