I have a 2015 RAM 3500 Dually equipped with an HO 6.7 and Asin 6 speed auto that only gets haul use mostly on the highway. It tows my 15k of fifth wheel RV and my 24’ enclosed car hauler to ferry the Barracuda on long trips. It was delivered with 18” NEXEN tires that seemed to be ok. Lost both fronts at 7800 miles on the odometer coming back from Mobile this weekend. Dealer confirmed all tire pressures were to spec. Not sure if it is an issue with the truck sitting to long in my concrete driveway between trips or just plain bad tires. Anyone have some opininions?
