Component Term
TPMS (Tyre Pressure Monitoring System)
Electronic sensors inside the wheel that monitor air pressure in real-time.
Deep Dive
TPMS sensors transmit pressure data to your dashboard. If a tyre drops below a certain threshold, a warning light appears. When changing rims, you MUST transfer these sensors to the new wheels, or the car will throw error codes.
