The Tire Pressure Monitoring System (TPMS) uses a dashboard warning light to alert the driver when one or more of a vehicle’s tires is significantly underinflated – a leading cause of tire failure.

A tire is considered significantly underinflated when its pressure is 25 percent below the vehicle manufacturer’s recommended tire inflation pressure.

Beginning with the 2006 model year, manufacturers will begin phasing TPMS into their new vehicles. By September 1, 2007, all new vehicles will have TPMS.
