Tire Pressure Monitoring System (TPMS)

Tire safety has been an area of focused research for GM for more than three decades, beginning in 1968 with the opening of its Tire and Wheel Systems Laboratory at the company’s Milford Proving Grounds in Milford, Michigan. The research lab and its team of engineers and technicians allowed GM to mount an ongoing effort to ensure that the original equipment tires on its vehicles perform safely and effectively.

The TPMS on GM vehicles alerts the driver if a tire is significantly under-inflated and needs attention. GM began equipping its cars with tire pressure monitors as early as 1987 and has been at the forefront of technology development over the past two decades. Today, more than four million GM vehicles are equipped with tire pressure monitors – more than any other manufacturer – and TPMS will be standard on all GM vehicles in the 2008 model year.

How it works

GM’s TPMS technology uses wireless sensors mounted in each wheel, which transmit information to an onboard receiver. These sensors monitor pressure continuously, A warning light on the instrument panel and a message displayed on the driver information center (when equipped) will alert the driver to check air pressure when any tire is significantly under-inflated. The driver information center also provides a real-time display, so that drivers can monitor their tire pressure.

Starting in 2007, tire pressure information will be included in the Vehicle Diagnostic email service provided by OnStar. This will help owners keep their tires properly inflated in order to optimize their fuel economy, ride, handling, and tire life.
