TPMS

TPMS (Tyre Pressure Monitoring System) is an electronic system that monitors tyre air pressure in real time and alerts the driver when pressure drops below a safe threshold. TPMS has been mandatory on all new cars sold in the EU and UK since November 2014. There are two types: direct TPMS (pressure sensors inside each tyre) and indirect TPMS (using ABS wheel speed sensors to detect pressure changes). TPMS sensors must be properly handled during tyre changes.
