Perfect PSI is debatable as each vehicle and tire will perform differently and demand different levels. The best way to find out what's best for your truck, loaded and unloaded is to apply a grease pencil or paint to the tread of the tire. Then you move the vehicle forward several revolutions of the tire to see how the wear pattern looks on the tread. If the Grease or Paint wears evenly all the way across the tread then you have the proper PSI for your vehicle based on that particular load.
