it's not BFG that's to blame, but the soft rubber, tall blocks, and intricate pattern can go sideways fast if the alignment is a hair off or driving style or location put extra abuse on the tires. for example, here in the foothills of GA every tire will be sensitive to outside edge wear simply because there's no such thing as a straight line in our roads. tires here are also prone to what I call "eraser wear" due to the amount of braking we do downhill. (so named because I use a pencil eraser to describe to people what is happening. but essentially the individual rubber blocks flex backwards under braking and wear a feathered pattern into the edge and needs to be cross-rotated to be put into the opposite rear spot on the truck to balance it out.)
