Since 2014, newly produced vehicles come with a tyre pressure monitoring system (TPMS) as standard.
This is a system that works by fitting sensor valves within each tyre - to monitor the pressure of the tyres. If there is a sudden drop in pressure, an alert is show on your vehicle dashboard.
It is important to ensure that TPMS sensors are regularly maintained. As a broken TPMS sensor can result in an MOT failure.
