The guys at the local tire shop mentioned the unloaded ride to me and told me that many of the owners of heavy trucks do lower the tire pressures to help with the ride. However the penalty for that is abnormal tire wear from under inflation.
Actually it can work both ways. If your tires are inflated to max for a load, and you are not carrying a load, you will wear out the middle of the tires faster.
My 2008 Ram 2500 has two inflation pressures listed on the door for the rear tires. 70 lbs for heavy loads and 45 lbs for light loads. If you want to "air down" after parking the trailer for the weekend or week, carry a decent compressor or make sure there is an air pump nearby.
