I have BFG AT 315/70/17 on my jeep wrangler that is parked during the winter because I use my 08 Ram for plowing. I have less than 13000 on the Jeep and tires but they are weather checked between the tread already,thinking because it's not driven in the winter months. My Toyota I had in 2002-20012 had BFG AT on them the entire time,couldn't wear them out. My Ram has good year duri-grip and they are ok but not great,actually suck plowing snow at times.
