Abstract
A load based tire pressure regulation system for trucks or trailers employing an air spring maintained at a variable pressure PAS depending upon the load on the truck or trailer, includes an air pilot pressure regulator receiving air at pressure PAS and air at the pressure of at least one tire of a truck or trailer, and configured to feed air to and bleed air from the at least one tire of the truck or trailer as a function of the load on the truck or trailer. The pressure regulator is configured to feed air to and bleed air from the at least one tire of the truck or trailer based upon the pressure of the air spring PAS as a function of the load on the air spring (FAS), and further upon the recommended pressure PT of the at least one tire as a function of the load on the tire (FT).
