TPMS delivers accurate real time tire pressure information to the driver of the vehicle via a gauge, a picto-gramme display, or a simple low pressure warning light.

The Rule:

  • NHSTA requires a TPMS to notify the driver when any tire is 25% below placard pressure.

  • Sensors in spare tires are not required.

  • System must alert driver if there is a system malfunction.

  • TPMS MIL (Malfunction Indicator Lamp) bulb must light on instrument panel when ignition is turned on to run position.

  • Placard decal must be present.
Readings are provided by pressure sensing transmitters mounted on the inside of each tire and sent to a central computer (ECU) for display on the dashboard. Direct TPMS enables simultaneous detection of under inflation in any or all of the four tires.
