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 controlling the duration of time that the tires are being deflated.
