"LT" tire pressures on Expedition
I moved up from "Heavy Load" tires on my Expedition to real "LT" tires. Max air pressure on the new tires is 80#, max pressure on the heavy load tires was 50#. I always ran my other tires at max press...

To the OP, you'll likely not get close to the loads that require max pressure on an E load tire. The beauty of heavier tires than needed on a lighter duty truck/tow rig, is having the headroom for anything you'll carry or haul, stiffer sidewalls and tougher tires in general and longer tread life than the same P or XL rated tire.
Remember, it's air that holds the vehicle up, not tires. Air pressure needed is a function of load. Run whatever pressures you need for the weight you're carrying. Want a little softer ride, stay on the low end of the needed pressure for the weight. Want a more solid, better handling ride, adjust up some from what is needed.
Door stickers are 1 size fits all guidelines and liability coverage for the mfgs against those who don't understand and are sue happy. That is all.
BTW, I also believe, within reason, that you cannot blow up a good rim or valve stem, or tire for that fact. This is not scientifically proven, but rather from many years of doing more with less when needed. I routinely run 55-60 psi in the rear tires of half tons with 44psi "max" tires when towing heavy. Freeway speeds, mountain passes, frost heave riddled highways, etc. it works.
