I have Michelin E rated tires on my truck that say 80 PSI for max.
My door pillar says use 60 PSI for the front tires and 70 PSI for the rear tires; and that is what I have been going by. Should or could I be using the 80 PSI when I have a heavy load or should I just stick with what the door pillar says? My door pillar and tires don’t really talk to me!
