Ford recommends 36psi. checked when cold all the way round. If you chose to run more or less that's up to you. As a large fleet shop manager/mechanic, its always been our companies policy to run what is on the door jam. We ignore what is on the tire as that's the max pressure for that tire and it can fit more that one specific vehicle.
I remember we had driver that had a heart attack and passed away at the wheel. He rolled his truck. The CHP impounded the truck and one of the first things they checked was the tire pressure, the second was the brakes, and then everything else. The tech that touched it last was very nerves. Fortunately all was OK for the tech, sadly not so much the driver.
