RunOnFlat Keeps rolling when flat

TPMS

TPMS stands for Tyre Pressure Monitoring System, an advanced tyre monitoring system that is recommended for all cars, but an absolute requirement for RunOnFlat tyres. After all, without an on-board monitoring system for RunOnFlat tyres, you wouldn't even know that you'd had a puncture and your tyre required servicing. That is why RunOnFlat tyres should only be fitted on cars that carries a TPMS system.

Indirect or direct TPMS

There are two different kinds of TPMS system: indirect TPMS systems do not measure air pressure directly from the tyre, but calculate it on the basis of ABS/ESP signals. As there is no need for additional sensors, this solution is highly cost-effective while providing a basic and functional monitoring system. The disadvantage is that the system isn't very accurate. Direct systems employ sensors on the tyre valves that transmit a radio signal to the car's bodywork. This highly accurate and reliable system also keeps track of tyre temperatures while giving you the most detailed information on your tyres' air pressure.
