Is tyre pressure checked at an MOT?

While the actual tyre pressure is not checked as part of an MOT test, a faulty Tyre Pressure Monitoring System (TPMS) will result in an MOT failure.

Like any electronic system, the TPMS can experience failures for various reasons. Common causes include battery depletion in the tyre pressure sensors, or the valve sensors becoming damaged or corroded over time.
