Typically the sticker on the door jamb is the recommended best ride for the truck. The tire itself has a max limit on it. Since different tires are used on many trucks, go somewhere in between. Mostly keep them even from side to side. The front tires can be a little lower than the rear and it will track better. The truck is heavy so it is not a big deal.
Light vehicles like a 2 door jeep handle funny if the tires are at max. If they look over inflated you can do the Chalk test. Mark across the tread in a few spots and drive around a smooth flatsurface like a parking garage. If you have Chalk on the outer tread, it is over inflated and ridding on the middle. I am not sure that test applied to ah heavy full sized truck.
You want the pressures the other way around. Less pressure in the rear, more in the front. All the heavy stuff is in the front of the truck. Rebel recommended is 10 psi difference, which is also what I ran on my old truck. On my stock Duratracs I run 52 front, 42 rear which is 3 less than the door sticker.
@RAM1500BLKEd, it also depends on if you have AT vs road tires, E rated vs P rated, etc. Typically the bigger, heavier AT tires require more pressure so the sidewalls don't bow out. You just need to find a balance of comfort, tire wear, and handling if you're not sure the pressure.
