The only part of the trailer that touches the road is the tyre, and the tyre's most important parameter is pressure. Low pressure silently raises fuel consumption by increasing rolling resistance, shortens tyre life through shoulder wear, and escalates the risk of a road blowout by increasing heat build-up. The problem is that it is invisible: a tyre that looks noticeably deflated is already below the critical threshold.
How Does the System Work?
A tyre pressure monitoring system (TPMS) continuously reads pressure and temperature data from a sensor on every wheel; when values fall below the threshold it warns the driver and, via telematics, the fleet centre. In advanced setups automatic inflation systems kick in and correct pressure while the vehicle is moving — without the driver even needing to notice.
Where the Gains Come From
- Lower rolling resistance and fuel consumption with correct pressure
- Longer tyre life and carcass value thanks to even wear
- Fewer delays caused by roadside breakdown and blowouts
- Data-driven management of tyre procurement using pressure-history data
Considering how many tyres are turning on a single trailer, manual checking one by one is always, in practice, incomplete. TPMS automates this task, and its cost pays for itself with even a single roadside breakdown prevented. Rarely in fleet efficiency does such a small piece of hardware touch such a wide area.
