Understood, and RAM changed for their reasons that are not stated. I was noting that the new rear tire pressure recommendations for the 2500s more accurately match the actual rated GAWR of the truck. The GAWR has not changed between generations, yet now with the identical tires on the same rims, RAM has lowered the recommended rear pressure from 80psi to 65psi (on the 20" tires).

With respect, the USTMA is not relevant to the changes that RAM made. USTMA describes the tires and the tire manufacturer recommendations, not the vehicle manufacturer recommendation changes I referenced.
