Tyre Pressure Monitoring System. Did you know that every car build since 1st January 2015 has this system. Simply put, in each of the road wheels, there is a sensor; your car is monitoring the tyre pressures of each wheel. When pressure is low, a warning light on your dashboard lets you know. And if any part of the system is faulty, then you vehicle will fail an MOT. As a tyre specialist & MOT centre, we are able to correct an issue should it arise.
