Abstract

A central tire deflation system for emergency vehicles, such as fire trucks, rescue vehicles located at airports, enabling the operator to deflate all of the tires of the emergency vehicle to a predetermined minimum pressure while traveling to a crash site so that the "footprint" of the tires is increased at or about the time the vehicle reaches soft terrain. The minimum tire pressure is obtained by a minimum pressure valve which senses tire pressure as the tires are being deflated and stops deflation of the tires when the predetermined minimum pressure is sensed.
