What is TPMS?

A tire pressure monitoring system (TPMS) is an electronic system that monitors the air pressure inside a tire in real time. Critical information is then relayed to an onboard processor that illuminates a warning light when tire pressure hits below a certain threshold.

The primary purpose of these systems is to:
‧Alert drivers of under-inflated tires
‧Reduce accidents caused by tire failure
‧Improve fuel economy
‧Reduce carbon emissions

The TREAD Act was passed in the fall of 2000 in response to vehicle safety concerns related to tire failure. The Act mandated the implementation of TPMS technology for all motor vehicles under 10,000 pounds. Initial implementation began at 20% in October 2005 and reached 100% for all models manufactured after September 2007. New vehicles are now required by law to have TPMS equipped.

Similar legislation has also passed in Europe. All new vehicles will be required by EU law to be equipped with TPMS technology starting from November 2014. The law does not apply to older models but many car manufacturers have already implemented TPMS ahead of the legislation change.
