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.

Different designated tire sizes use different load inflation charts. The correct information for the installed OE tires is on the vehicle certification label.
