You also have to be aware that changing tire pressures also affects tire wear. Over inflate and they will wear prematurely down the middle.
One should really take it to the scales, especially with dual axles, to determine what is the best tire pressure settings fully loaded.
There is a table\link floating around here on this site that goes through the best way to determine proper tire pressures after conducting these tests on a scale.
P.S. I think BigJohnD posted it.
