TPMS: What You Need to Know

If your car was registered after January 1st 2012, you are likely to have a TMPS system in your car. If your light is on your car could fail its M.O.T.

There are 32 Million cars across Europe fitted with TPMS (Tyre Pressure Monitoring System). Modern Tyres, with our Industry leading TPMS solution are your local TPMS Experts. If you see this light, call in and see us Immediately.

 

Direct TPMS employ pressure sensors on each wheel. The sensors physically measure the tyre pressure in each tyre and report it to the vehicle's instrument cluster or a corresponding monitor. Some units also measure and alert temperatures of the tyre as well. These systems can identify under-inflation in any combination, be it one tyre or all, simultaneously. Although the systems vary in transmitting options, many TPMS display real time tyre pressures at each location monitored whether the vehicle is moving or parked.

Indirect TPMS do not use physical pressure sensors but measure air pressures by monitoring individual wheel rotational speeds and other signals available outside of the tyre itself. iTPMS cannot measure or display absolute pressure values, they are relative by nature and have to be reset by the driver once the tyres are checked and all pressures adjusted correctly. The reset is normally done either by a physical button or in a menu of the on-board computer. iTPMS are, compared to dTPMS, more sensitive to the influences of different tyres and external influences like road surfaces and driving speed or style.

If this light is on even though your tyres might be fine, you could have a fault with your system and you won’t know if there is a problem with your tyres when it does happen.
