I just went from 33" cooper mud tires to BFG AT 35"s. Huge difference in drive-ability on the road (Not a DD, but not a trailer queen either, and I have to get it to Moab somehow!). The old mud tires were a glorified AT, and were really floppy feeling on the road, it made the steering seem very unsteady on the highway. I love the stiffer sidewalls on the BFG AT's, even at 2" bigger, they feel much better on the road. Off the road, the BFG AT is one of the best rock-grippers I saw after watching 50+ jeeps creep off the mini-cliff on metal masher. I was sold when I saw that. It's only weakness is mud, but in Colorado I see snow more than mud, and these AT's are much better in the snow than any mud tire just because of the tread design.
