A TPMS or "Tire Pressure Monitoring System" electronically monitors the air pressure inside your tires. Depending on your vehicle, the TPMS reports the tire-pressure information, through a gauge, a pictogram display, or a low-pressure warning light. This system can be divided into two different types—direct (dTPMS) and indirect (iTPMS). As of September 1, 2007, the TREAD (Transportation Recall Enhanced Accountability and Documentation) Act requires that all vehicles sold in the U.S. be equipped with one of these types.
Direct TPMS reports tire pressure in real-time through pressure sensors installed directly in the valve of each tire.
Indirect TPMS uses the car's anti-lock braking systems (ABS) to approximate tire pressure. Since tire inflation levels affect tire rotation, indirect TPMS also relies on the differences in wheel rotation to detect under-inflation.Benefits of TPMS:
- Increased driver safety: Recognize under-inflated tires before they malfunction. Properly inflated tires add stability, greater handling, and braking efficiency while providing better safety for the driver, the vehicle, and others on the road.
- Extend tire life: Under inflation contributes to heat buildup, tire degradation, ply separation, and sidewall/casing breakdowns.
- Better fuel economy: Properly inflated tires reduce rolling resistance and improve fuel economy.
