I feel like running tire solely by what door says is a bad idea. Can you say ford explorer debacle? Common sense must be used if my tire says max psi of 80 and decide I am going to haul a load that is 6000 lbs I should add some air to compensate for extra weight as long as I am under max rating of tire.
I will also point out that sticker was for the tires that came on the vehicle and most of us are running tires that are different size and rating. My truck came with passenger wrangler HP but now has light truck load range E tires. That sticker now means nothing. I have experimented and ride obviously nice at 35 but the truck handles and works as a truck better at 37 or 38. Just my tangent on tire pressure.
