- Different tyres and pressures apply to some Heavy-Duty Payload / higher-payload vehicles and certain markets; the stated 36 psi must not automatically be applied to LT configurations. Indices and size combinations also varied by year and trim. The pressure for a specific VIN is reliably determined from the vehicle’s placard or the manual for the relevant market; there is no universal value for all RAM 1500 2019–present.
