Tyre Pressure Monitoring System (TPMS)
In Arabicنظام مراقبة ضغط الإطارات (TPMS)
Sensors that measure the air pressure, and often the temperature, inside each tyre and warn when a tyre loses pressure or runs hot.
What is a tyre pressure monitoring system (TPMS) in fleet management?
In a direct system a sensor is fitted to each wheel, on the valve or strapped inside the wheel, and sends pressure and temperature wirelessly to a display in the cab or to a receiver. An indirect system, found on some cars, has no pressure sensors: it infers a soft tyre from the ABS wheel-speed signals, because an under-inflated tyre turns slightly faster. Several markets, including the United States and the European Union, require TPMS on new passenger cars.
In a fleet, its value shows when tyre warnings reach someone other than the driver. Some TPMS units connect to the tracker, by cable or over Bluetooth, so pressure and temperature travel with the vehicle's position to the fleet platform.

Why does a tyre pressure monitoring system (TPMS) matter in fleet management?
An under-inflated tyre flexes more, heats up, wears faster and raises fuel consumption, and in Gulf summers, on hot asphalt with a full load, that is how many blowouts start. A blowout on a loaded truck can mean a rollover, a closed road and a lost load. Catching a slow leak early turns that into a short stop at a tyre shop, and keeping pressures right extends the life of the tyres, which are among the largest running costs.
What you gain
- Fewer tyre blowouts
- Longer tyre life
- Lower fuel consumption
How does Safee help you manage tyres and monitor their pressure?
Safee's platform is built to take in a wide range of vehicle sensors, tyre sensors among them; whether a particular TPMS can pass its readings through the tracker depends on the sensor and tracker models, so confirm it with the Safee team before you buy. Whatever system you fit, Safee supports the tyre programme around it: mileage per vehicle to schedule maintenance tasks for rotation and replacement, tyre count and size in each vehicle's record, and driver mobile app tasks asking for pressure readings or tyre photos.
A field example
An intercity haulier in Tabuk running 40 trucks on the Riyadh and Jeddah routes had 11 tyre blowouts in one summer, two of which ended in a lost load. It fitted direct TPMS with in-cab displays to all trucks and their trailers, set Safee maintenance tasks to rotate tyres every 40,000 km, and had supervisors send a driver mobile app task asking for tyre photos before every long trip, to catch cuts and bulges. The next summer there were three blowouts and no lost loads, and tyre spending fell by 14%.
Frequently asked questions
Can a TPMS replace manual pressure checks?
Largely, once it is fitted and its sensors are maintained, but a visual check is still needed to catch the cuts, bulges and uneven wear that pressure does not reveal.
How long do TPMS sensor batteries last?
Usually five to ten years, depending on the sensor type and how often it transmits. Plan replacement around tyre changes, since the sensor sits inside the wheel.
