I personally have no use for BFG tires. I have a set of(well 3 now) the old style M/T's in 315 /75R16 that I have been rotating between trucks for 5 years now, they wear like iron, has to be 40K on them and they're still better than 65%, that said, I still wouldn't have bought them if I hadn't of gotten a smoking deal on them($800 practicly new with a set of Helo 16x10 maxx 8's.)
I have a set of General Grabber AT2's in 235/85R16 that I had studded in 05, I have run them primarily as an October to April tire, so while they do see snow, they also have seen a fair bit of pavement, but no real hot temps on the truck. Between 3 Trucks, they are probably nearing the 85K mile mark, and while I wouldn't want to run them a full winter on a highway truck anymore(the studs are starting to leave the tire, they've been on the plow truck for 3 winters now), they are still a good ways from the wear bars.
My work truck(08 2500HD Duramax) has a set of 235/85 BFG A/T's we put on it last september, at 17K miles, the majority of which were put on last winter, and having been rotated regularly, they are probably no better than 35%
I had to replace one of my 315's, and ended up with a Kelly safari TSR, I'm actually quite impressed by the tire build itself, it balanced well, and, even moreso, it's actually a load range E tire, not often you find them in that size.
