Tire Air Pressure Questions

[camper4]

The panel inside the door is the cold tire pressure the manufacturer has selected for the best performance of your truck with the tires it originally came with. My truck states 55 front and 80 rear.
Those numbers are for cold tires. The 80psi max number stated on the tire side wall is for cold tires. The tires will increase in psi while driving but that is factored into the cold rating.
I hope that helps some.
