ok I have a quick question. I know that the all terrain tire is probably lasts longer, but how much longer than a mud tire??? I like the long lasting BF AT KO, but I like the look of the Mud terrain tire (or any mud terrain for that matter). I do some moderate wheeling, but nothing too adventerous, mostly snow and some forest stuff. So the million dollar question......what is the mileage difference in a MT and an AT????
