How TPMS Can Help Cut Down Expenses for Prime Movers

Being the powerhouse of a vehicle combination, prime movers are built to haul semi-trailers, transport heavy machinery and move essential goods across vast distances. In Australia, where long-haul routes and remote regions are the norm, a prime mover’s reliability isn’t just about convenient - it’s critical to basic logistics. A single breakdown can disrupt supply chains, cause costly delays and compromise road safety.

This is where TPMS (Tyre Pressure Monitoring Systems) come in. They continuously monitor the pressure and temperature of each tyre in real time - alerting drivers to any irregularities before they become a serious problem. By providing real time insights into tyre conditions, TPMS becomes a tool not only to prevent blowouts but also reduce operating costs.

How a TPMS Works

At its core, a TPMS is like a set of digital eyes on your tyres. They constantly watching over them to keep you safe and your vehicle performing at its best. TPMS uses sensors to measure two critical factors - tyre pressure and tyre temperature.

Once the sensors detect the pressure and temperature in each tyre, they transmit this information wirelessly to a display inside the cabin or a fleet management system. If a tyre begins to lose pressure rapidly, the pressure falls out of the desired pressure range or overheats, the system immediately alerts the driver through visual and audible warnings. This real-time monitoring allows drivers to take action before a small problem escalates into a major safety risk.

There are two main types of sensors. Internal Sensors are installed inside the tyre - secured to your tyres rim.  These sensors provide highly accurate readings and are shielded from external elements. External Sensors are fitted onto your vehicle's valve stem. They are easier to install hence offering quick, low-maintenance monitoring.

How TPMS for Personal Vehicle Differs from TPMS used for Commercial Trucking Applications

Prime movers operate under conditions far more demanding than regular passenger vehicles. They carry heavy loads, cover long distances on highways and often encounter high ambient temperatures. These factors put enormous stress on tyres, making proper pressure and temperature management essential. Promata’s TPMS systems are specifically designed to meet these challenges.

Unlike passenger vehicles, prime movers often have multiple axles with dual tyre configurations. This complexity is exacerbated by the fact that prime movers pull trailers. As such, the sensors need to be adapted for trailer kits as well. All in all, a prime mover pulling a trailer can have dozens of tyres to monitor as opposed to the 4 standard in regular passenger vehicles. TPMS systems for heavy-duty vehicles such as the Mata 7 are engineered to handle this complexity - accurately monitoring each tyre on the vehicle.

Additionally, the tyre pressure in prime movers is often significantly higher than the ones in cars. While 30 to 40 PSI is the norm for cars travelling down highways, 100-120 PSI is common for prime movers. Also, there may be a pressure difference between the steer wheels and the drive wheels.

Do TPMS Make Sense as an Investment

For prime movers, the answer is a resounding yes. Investing in a TPMS isn’t just about safety - it’s a smart financial decision that actually pays for itself over time.

One of the biggest hidden costs in heavy-duty vehicles comes from underinflated tyres. Even a small drop in tyre pressure increases rolling resistance, forcing the engine to work harder and burn more fuel. Studies show that a tyre running below optimal pressure can increase fuel consumption by 2% to 5%, a significant cost when you factor in the long distances covered by prime movers every week.

TPMS also help tyres last longer. Maintaining the correct pressure can extend tyre life by over 15% - effectively like getting a 15% discount every time you need to replace tyres. Across a fleet of vehicles, this adds up to substantial savings.

Manually checking tyre pressure is another hidden drain on resources. Using a gauge is time-consuming, inconvenient and often inconsistent. TPMS automates this process, saving hours of labour each month and ensuring accurate, real-time readings every time.
From a logistics point of view, tyres are the leading cause of truck downtime. A single breakdown can ripple across operations, resulting in lost deliveries, missed deadlines and idle operators. Keeping your tyres in good shape keeps your trucks running. This not only makes money but is crucial to the proper functioning of the Australian economy.

Finally, TPMS isn’t just good for your bottom line - it’s better for the environment. Maintaining correct tyre pressure reduces fuel consumption and tyre waste - lowering emissions and contributing to more sustainable fleet operations.
