Purchased four of these tires from Costco. We drive all summer long on very rough gravel roads, the tires lasted one year. We had hoped that they would have stood up to the miles of gravel roads a lot better than they did. They are great handling tires for all terrain tires and took on the conditions that we put them through. The tread however got cut up from the gravel roads. These aren't just normal gravel roads that we travel on. They are made up of large gravel from the mining quarries. If the tire were being used for general transportation purposes, they are an excellent choice, smooth ride, handle great. They just didn't hold up to the punishment of a hard gravel road. I would purchase them again for a different vehicle but not for the work truck. Don't get me wrong BF Goodrich makes a great tire, just be sure that they work for the purpose you need them to work for.
