While on a trip to Bristol Tn. last weekend i was looking the truck over in our hotel parking-lot and was surprised to see the steel belts on my tires. I went to a Bfgoodriche dealer in Johnson city and he came out,looked over the tires and said yep, they are bad and you need to have them replaced. He also said this was not the first set that he had seen go bad. He said they were all in size 285/75-16. The point of this story is if you run this size go and look for small slits between the outer lugs about 1 inch in from the sidewall. They are at the edge of the steel belts.
