I don't know how convenient for you but might give Discount Tire a try. They may not be the cheapest but I know for a fact they do stand behind what they sell, they sell road-hazard and certificates, can get flats fixed and rotated and balanced for free, as long as you own the truck. I had bfg's on a 98 Dodge diesel truck and told them I traded trucks and they even took some of that money I spent and put it toward my Michelins on the new truck I bought.
