Suggest you read the charts
You can do what you want with the pressure , but i dont know for you but im not an engineer , however the real engineer at Ford per example are the one studying calculating nd determining the best pressure for a good ride, good handling, durability and supporting the maximum load for the applicationl.
So in theory yes you can crank the pressure to whats on the sidewall, but its not the right thing to do, the engineer have the knowledge and determine the best overall pressure.
Its fairly simple, the tire manuf. determine a press for a maximum load per tire, and this pressure will never change no matter where the tire is installed. Look closely at your tire and see what is written on them about the recommended pressure, you may discover something there. Few exception will show unloaded and loaded pressure option that you have for a given tire size .but hey to each is own
at the end who cares about the chart and whats on the sidewall. You should never overload your truck, and since you are not doing it, the pressure set by the truck manuf. is the one you should use..fully .loaded half loaded or unloaded .choosing a different pressure is playing engineer....its not recommended i would say but we live in a free world so crank them up as you please lol
