My sentiments almost exactly. I have a 2500 RAM diesel now and been driving a diesel since 2007. First let me say the diesels chew up tires like a new puppy and leather boots. I get maybe, maybe 20,000 miles out of a set of tires, and I've tried Michelin, Good Year, Firestone, Cooper, and Arctic Claw.
Sounds like you have a problem with the truck. I have an '08 Ram diesel. It had new dealer installed BFG Rugged Trail A/T's when I bought in in '12. They lasted 50k and I now have them on my horse trailer. They should be good for maybe 10k on it.
