I had Yokahamas on my Tundra, they sucked. I bought Cooper Discoverers, I liked them so much I bought a set for my wife's Honda CRV. I'm sold on Coopers, they seem to last forever.Similiar experience. When i was hauling around a big 40ft 4horse with living quarters trailer......the Coopers i had on the dually got roughly 10,000 -15000 more miles out of set than any other.
Just put on a set of Falkens. Agree with Celtic on these.If you like BFG's, try the Falken Wildpeak AT3W. These tires last longer, are quieter, do better in the mud. I have ran BFG's, Nitto's, Coopers, Yokohama's, Goodyears, and so far the Falkens are the best AT I have ran.
