I have TOYO Open Country A/T's on my Yukon, and I generally like them, they're quiet, have good traction, and the last set I put 50,000 miles on them, with about 10,000 left, but I didn't want to drive all winter on mostly bald tires. That being said, I think this spring I'm going to swap on some Hankook Dynapro A/T's. My brother runs them on his Trooper, and he loves them, and they're a good looking tire.
