Doesn't matter the year, air pressure in tires is not one pressure fits all situations. The payload sticker is for max payload not empty load.
I adjust my pressure based on load, so empty I run about 45 to 50 psi rear, loaded I increase to 65 to 70 psi. My loaded rear axle weighs 5,500#, my tires have an 80 psi capacity of 6,830# I don't need 80 psi to carry the load safely.
