I purchased a 2015 2500. Truck came lifted on 37 x 13.5 R20s. Tires are Toyo Open Country MT. The tires say to inflate to 65psi cold, but the truck says 80psi (for the rear). As a result my TPMS light stays on and shows both rear tires under inflated. What are people doing about this? Do I just ignore the light? Can it be reprogramed by the dealer? I do not want to over inflate the tires. Thanks. Oh and a pic.
