Proper tyre inflation is critical for the safety, performance, and cost-efficiency of fleet vehicles, making tyre pressure monitoring systems (TPMS) an indispensable feature. But what exactly is TPMS, how does it work, and why is it important for Australian fleets?
This guide covers everything you need to know about TPMS, focusing on key challenges faced by fleets in Australia such as tyre loss due to pressure issues, asset loss from fire risks, high fuel consumption, late deliveries caused by punctures, time lost collecting odometer data, and managing high workshop loads with reactive maintenance.
TPMS, or tyre pressure monitoring system, tracks the tyre pressure levels of a vehicle and alerts drivers promptly when there’s a significant deviation or imbalance. These systems are vital to maintain optimal tyre conditions, preventing blowouts - a common cause of accidents and breakdowns on Australian roads.
TPMS uses compact sensors installed on each wheel to measure tyre pressure. This data is transmitted wirelessly to a central system, which triggers alerts when pressure falls below safe levels. TPMS comes in two main types:
Direct TPMS uses sensors on each wheel’s valve to provide real-time tyre pressure and temperature readings, sending instant alerts if any tyre is underinflated or overheating.
Pros: Highly accurate readings, no need for recalibration after inflation or rotation, longer sensor battery life Cons: Sensors can be damaged during tyre changes, higher cost
Indirect TPMS estimates tyre pressure by monitoring wheel rotation speeds via ABS sensors. An underinflated tyre rotates faster, triggering alerts.
Pros: More cost-effective, less frequent calibration
Cons: Requires resetting after maintenance, less precise readings, can misinterpret tyre wear
TPMS alerts warn you of significant pressure drops, but this doesn’t replace regular manual inspections. Fleet drivers should routinely check tyre pressure with a gauge and inspect tread depth. This helps detect minor issues before they escalate and verifies TPMS accuracy.
One of the most critical risks tied to poor tyre maintenance is tyre-related fires. Underinflated or damaged tyres can overheat, especially during long trips on Australia’s extensive highways and in hot climates.
Overheating may lead to tyre blowouts that can spark fires, resulting in severe asset damage, endangering driver safety, and causing costly operational disruptions.
Maintaining correct tyre pressure helps reduce the risk of overheating and fire. Early warnings allow fleet managers to intervene before minor tyre issues escalate into dangerous and costly incidents, protecting both lives and valuable assets.
Direct TPMS sensors have batteries that eventually require replacement. Sensors may also fail due to weather, corrosion, or damage. Regular servicing with specialist diagnostic tools ensures system accuracy and prevents MOT failures. Valve caps and cores should be replaced during tyre changes to maintain airtight seals. Indirect TPMS systems require recalibration after tyre inflation or rotation, but have no batteries to replace.
