Real-time truck tyre pressure monitoring is here with Goodyear (almost)
The Goodyear TPMS could have multiple benefits for fleet operators
One of the bugbears of fleet managers is wear and tear on truck tyres. One of the most common causes of extra wear and tear on a tyre is running at incorrect tyre pressure, which also causes handling and safety issues and harms fuel consumption. All these benefits of maintaining the correct pressure in a truck’s tyres are well known. Yet doing so remains difficult.
It’s hard to check tyre pressure on trucks that are constantly on the move. When they are parked long enough for pressures to be checked, it’s not an easy job. Getting to the valves can cause new leaks that cause new problems.
All these issues may disappear soon. Goodyear & Dunlop Australia are currently trialling their real-time Tyre Pressure Monitoring System (TPMS), and indications are that it will be introduced as a service later this year.
How does the real-time TPMS work?
Goodyear’s system uses sensors on each wheel. These transmit pressure and temperature information every two minutes to a telematics box on the truck.
The telematics box transmits this information via mobile networks to a cloud-based server. This is where the magic really works. The information is crunched, and Goodyear applies a set of algorithms to it. These tell the system if an issue has occurred, so that the fleet manager can decide if action must be taken. This should prevent truck tyre issues becoming bigger problems.
The system doesn’t simply consider the tyre pressure. It also considers the effect that the temperature of the tyre has on tyre pressure.
What difference does the TPMS make to a fleet?
When drivers and technicians make manual tyre pressure checks, it is impossible to accurately allow for the effect of temperature on tyre pressure. While these changes in pressure may be small, they could signal a leak. Having this advanced warning, especially from trucks that are on the road and in motion, could help to prevent more costly repairs, the need for new tyres, or, in extreme cases, life-threatening accidents.
Making a repair to a small leak puncture could prolong a truck tyre’s life by several thousand kilometres, as well as that of the partner tyre in dual applications.
Alerts from the TPMS can also prevent the need for dangerous roadside repairs. When the system tells a fleet manager that there is an issue, time can be allotted to make the repair in the depot or at a tyre specialist’s shop. This early warning and prompt action also helps to prevent further damage to the tyre.
The TPMS alerts also provide information about other issues, such as uneven loading or problems with the brakes.
When will the Goodyear real-time TPMS go live?
The trials being carried out by Goodyear are proving very promising, with issues being discovered within minutes with pinpoint accuracy. While fewer than 1% of tyres being tested have needed urgent attention, the ability to know exactly which tyre and where on the tyre an issue exists is proving to be a big benefit to users.
The success to date has prompted Goodyear to announce that they will exhibit the system at the Brisbane Truck Show from 16th May 2019, and it is expected to be offered as a commercial service later this year. We’ll keep you posted as soon as we know for certain.
