I have ran both of these tires in multiple sizes and my opinion is that the MT/R is 10 times the tire, but I hate mud. I use them for on highway, rocks, slickrock, and good ole trails. The things that I hated about the BFG is the the wet traction, and the fact that in the ice and snow I would have been just as well off with drag slicks. Now I know that you can't expect a mud tire to be good on snow and ice, but the MT/R is by far the best one that I have run and I am on tire set # 15 on my truck so I have run a few tires. Like I said though, I hate mud so I have no idea which one would do better, I think the mud has just as much to do with power/weight ratio as it does tires.
