Determining Tire Pressure
I have read that you should not pay much attention to the inflation psi marked on the tires, but rather go by the vehicle recommendation printed on the door edge. In other information I have found ch...

The tire company puts a recommended pressure on the tire for a reason!
Actually, I've never seen a "recommended" pressure on tires.
What you normally find is the maximum allowed pressure for the tire. But it may not be necessary or even desirable to inflate your tires to the maximum.
Any given tire's load rating is determined by how much air is in it. Generally speaking, the more air in it, the more load it will endure, up to its maximum rating.
For example, I have Cooper tires on my RV. As I recall they can be inflated up to like 90 PSI. But my rims are only good to 65 PSI. My RV owner's manual says I should inflate the rear tires to 62 PSI and the front tires to 58 PSI. The critical issue is what is the load rating of the tire at 65 PSI, since I can't inflate them to the full maximum rating.
