A new Pressure Limiting Tire Deflator System for deflating a tire to a pre-selected pressure for increasing traction during travel within loose dirt or sand. The inventive device includes a spherical head formed for engaging a valve stem, an elongated neck, an air passage projecting through the spherical head and through the elongated neck, a plurality of air release passages, and a pressure limiter within the air passage. The pressure limiter is adjustable for preventing air pressure within the tire from falling below the pre-selected pressure.
