My BFGs are starting to wear on the inner part of the tire. My tire guy tells me that the toe might be out. Had it aligned at the beginning of the year down at Truck Toyz. Probably has between 5-6,000 miles since the alignment. I balance and rotate every 3500 miles. The pattern is on all 4 tires but looks worse on the front. Tires have about 15,000 miles total and are my second pair. The first set never wore like this. Don't really know that much about tire wear; never had to deal with it on any other trucks. Any ideas?
