I thought the michelins that came on my wife's Yukon XL were the worst tires I've ever driven on snowy/icey roads. They also started to chunk apart after a lot of gravel road. I live in northwestern Montana where we get plenty of snow.
I thought BFG A/Ts did really well in the winter but were soft and wore fast in the summer.
I have Toyo Open Country A/Ts on the wife's rig...much better than the michelins.
Toyo M-55's on my duramax and have no complaints.
I also have had Bridgestone Dueler A/T's and Firestone Steeltex A/T's and liked both of them.
