I have been running Toyo Open Country M/T's on my Landcruiser and my Duramax. They work well and have great traction, but don't last that long (30k miles or so). I intend to try a set of Hankook M/T's the next go around on the Duramax. I prefer a mud terrain for my location and what I do with the vehicles. I had the tires on the Landcruiser siped when new and it performs great in the snow and ice. Much better then the Open Country A/T's I had previously (those weren't siped, however).
