IRTE: tyre servicing and the circular economy
Transport engineering body IRTE has highlighted the part tyre servicing can play in cutting costs and driving sustainability, as part of the circular economy.
While fleet managers are increasingly tasked with overseeing a myriad of vehicle components, tyres remain a cornerstone of operational efficiency and safety, the organisation says.
“Modern tyres and associated technologies not only contribute to reducing costs but also play a critical role in advancing the circular economy,” said IRTE technical product manager, Leo Hubbard MSOE MIRTE (pictured, right).
“From extending tyre life cycles to harnessing data-driven insights, tyre servicing has become an integral part of fleet management strategies.”
Gone are the days when tyre manufacturers solely produced tyres, he says; today, they offer comprehensive solutions to optimise tyre usage, reduce waste, and enhance sustainability.
“Many commercial vehicle and bus tyres are designed to follow a lifecycle of use, regroove, remould, and recycle. This approach not only extends tyre longevity but also aligns with the principles of the circular economy by minimising waste and reducing costs.
“However, adopting this lifecycle approach adds responsibilities for fleet engineers. Regular checks on tyre pressure, tread depth, and overall condition are essential to maximise performance and safety.
“These tasks can be particularly challenging for vehicles with aerodynamic side fairings, complex bodywork, or twin tyres, where access to valves and treads can be limited.”
Daily walk-around checks are crucial for identifying visible signs of wear and damage, Leo adds, but says these alone are insufficient – and warns that neglecting the measurement of tyre pressure or tread depth can have significant consequences.
“While tyres account for only three per cent of a fleet’s total costs, they influence over 30 per cent of operating expenses when factoring in fuel efficiency, breakdowns, maintenance, and productivity losses.”
Technological advancements have revolutionised tyre maintenance, says Leo; tyre pressure monitoring systems (TPMS) provide real-time data on tyre pressure and temperature.
“These systems alert drivers and fleet managers to potential issues, enabling proactive maintenance. This data is transmitted via telematics, ensuring seamless communication between vehicles and fleet management systems.
“Such tools provide actionable insights, alerting managers to pressure, wear, and other critical parameters, thus reducing downtime and improving safety.”
The shift towards electric vehicles (EVs) has prompted tyre manufacturers to develop specialised products, Leo says.
“At the IAA Transportation show in Hanover, Continental unveiled the Conti Urban HA 5, a bus tyre designed for EVs. With features like low rolling resistance and recycled materials, this tyre enhances sustainability while improving mileage and reducing replacement frequency.
“Similarly, Hankook’s e-Smart City AU56 tyre caters to electric city buses, offering extended range, high torque transfer, and increased weight ratings to accommodate battery packs. The tyre’s design also supports regrooving and retreading, further contributing to resource conservation.”
Tyre designs now incorporate features to ensure durability and performance throughout their lifecycle, says Leo; for instance, Hankook’s AU56 tyre uses S-shaped sipes and 3D-printed grooves that maintain grip as the tyre wears.
“Step-shaped tread blocks prevent stone trapping, while reinforced sidewalls protect against kerb impacts. These innovations not only improve safety but also align with circular economy principles by facilitating extended use and material recovery.”
The integration of advanced tyre technologies and digital management tools marks a significant shift in fleet operations, he observes.
“By embracing these innovations, fleet managers can reduce costs, improve safety, and contribute to sustainability. Tyres, once seen as a simple expense, are now a strategic asset—an essential component of a greener, more efficient transport system.
“As the industry continues to evolve, the emphasis on the circular economy will only grow stronger. From leveraging data for smarter maintenance to adopting tyres designed for extended lifecycles, the future of tyre and wheel servicing is one of innovation and sustainability.
“Fleet managers who adapt to these changes will not only enhance their operations but also lead the charge towards a more sustainable transport sector.”
