My 2015 F-150 came new with Passenger-rated tires, and I have been disappointed with the movement / squishiness / feeling of instability I get when towing our loaded 6500 lb. travel trailer. So tod...

Look up the load inflation tables for the tire and go from there. They pressures are based on weight and the weight listed is per tire usually not per axle so if the rear axle of your truck weighs 3500lbs that is 1750 per tire and that is weight you would use for the pressure rating
example- in link scroll down to the light truck tire section starting on page L7 and from there find your tire size it will show you the inflation pressures needed for various weights up to the tire size max psi

Generally that is true and you definitely need to air those "puppies" down when not towing. When towing I run 80 in the rear and 65 in the front (6,000lb actual load on the rear and 4,400 on the front). When not towing my Van run around 7,000 lbs (3500 on each axle) and while the inflation tables call for around 40psi per tire I find that 50 to 55 in the rear and 45 to 50 in the front give me the best overall ride and handling. I guess I'm saying use the load tables and maybe add 5 to 10 psi above what is called for and see how that feels.
