As I speak with industry members, regulators and legislators I continue to be stunned by the lack of appreciation of the very critical role that tyres play in our societies.

Governments bleat about fuel security “investing” precious currency to prop up petroleum fuel storage and production in the face of the ever-expanding development of electric vehicles and more recently the advent of hydrogen as a viable fuel with thanks to the PV (solar) industry advancements. Tyres? What do you mean tyres? Without tyres our societies would grind to a halt in the near term. How are they not a strategic consideration?

Our industries (tyre, road freight transport, mining, public transport and leisure) are facing sufficient difficulties with COVID as well as international shipping challenges to be faced with continued ignorance and negligence by our legislators and regulators.

Please review your countries legislative requirements in regards tyre inflation for light vehicles (say <4,500 kgs) and then the same requirement for heavy vehicles (>4,500 kgs). What do you find?

Mostly I think you will find that tyre inflation pressures are regulated for light vehicles via the vehicle manufacturers tyre placard. For heavy vehicles there is little, if any, such requirement. To illustrate the yawning gap between reality and regulation one peak heavy transport regulatory body published a procedure for roller brake testing for heavy vehicles. The procedure details in minute detail the requirements of the pneumatic system on the truck under test yet merely stated “tyres should be inflated.” As everyone in the tyre industry understands a tyre can be inflated at low pressures totally unrelated to actual operating pressures. What connects the brakes to the pavement? Tyres!

I’ve spoken at length about the absolute requirement for a tyre to be appropriately inflated. This is basic physics, the air molecules captured within the tyre’s air chamber actually support the applied loads. If there are insufficient molecules of air the tyre will be overworked so overheat and so enter a failure phase. There are other requirements for the inflation being the actual shaping of the tyre to interface with the pavement at the optimum level, read traction. A wide based tyre requires special construction to maintain the tread platform shape. If the inflation pressure is not at the manufacturer’s specified level will this critical shape be maintained? Then it is not only the performance of the tyre in question but also the safety of the vehicle and that of the general public in the areas this vehicle operates in.

The extensive report produced by the TNO Organisation (TNO 2013 R10986) detailed not only the exhaust emissions as a result of inappropriately inflated tyres but also the road safety outcomes. This paper is now just over eight years old but the situation with real time pressure monitoring for heavy vehicles remains as it was, 50 years or more ago. WHY? Are our regulators asleep at the wheel (or tyre some may say) through entrenched inaction and ignorance? Or is it that there are just “no votes” in tyres and everyone just ASSuMes their tyres are “ok”?

EV tyres

With the advent of electric vehicles, the ramifications for tyres are huge. In the past internal combustion engines (ICE) built up torque over a rev range, drivelines multiplied the torque developed and for heavy vehicles there is a sweet spot for torque. The multi speed gearboxes assisted the driver to maintain forward motion within this torque sweet spot. Electric motors apply maximum torque over most of their operating range. From the instant the power is applied by the driver (be that human or robotic) the tyres are under peak stress. Any deficiency within the tyre will be magnified with detrimental results. Such a deficiency may be of a manufacturing nature but this is largely controllable by the manufacturer. What is not currently controllable is the human maintenance factor, the applied inflation pressure.

Tyre manufacturers have for as long as they have been manufacturing tyres been informative about the criticality of appropriate tyre inflation. There are untold charts and pictorials showing how a tyre is influenced by under or over inflation yet our regulators and legislators continue to keep their heads buried deep out of the light. WHY when tyres are such a critical component of our modern-day motor vehicle? I would charge ignorance and negligence on one hand but then on the other suggest that because tyres work as well as they do, are as forgiving (by nature of their fundamental flexible design) our “guiding powers” can focus on other trendy and glamorous aspects such as stability control or autonomous braking. An important question for these people to consider and respond to; “what item on the vehicle transfers the power (and so directly influence these vehicle control systems) from the vehicle to the pavement (be that power tractive or retardation)? Yes of course, the humble tyre.

So, when a government sponsored or publicly funded body involved in road safety ignores tyres (for whatever reason, ignorance or negligence) are they really serving the interests of our communities and societies or are they just -- I should stop there but you know where I’m going!

The technology to monitor tyre pressures in real time is and has now been available for decades. The TREAD Act (USA) mandated tyre pressure monitoring (TPMS) for light vehicles in the USA in the year 2000. This year TPMS gets a key for its birthday, yes well and truly a mature product (some may say adult) and industry yet, our regulators and legislators continue to ignore the humble tyre.

The upsides of maintaining tyres at an appropriate pressure I’ve discussed previously, all positive. The same detail has been published in many papers (such as the TNO paper!) but we as an industry continue to live in the past whilst adopting hi-tech solutions for other aspects of our industries, e.g., GPS tracking, fatigue monitoring, reefer monitoring and control, real time video surveillance of the drivers and the surrounding traffic conditions. Why? To me there is little respect paid to the critical role the tyre provides for us. So many users do not consider how the tyre works for them and why the simplest of tasks will enhance the performance, yes, I speak of inflation maintenance. Without respect the tyre will never be recognised for the contribution it has made and continues to make.

I publicly and openly challenge our tyre manufacturers as a collective to mount an education campaign to enhance the level of respect the general public has about tyres. The TIA (US) and USTMA have local campaigns on behalf of their members but I consider that until the tyre manufacturers as a collective industry actual improve the level of respect for the humble tyre we will be chasing our tails on a race to the bottom. Our tyres deserve better!

What about Michelin, Bridgestone, Goodyear, Continental, BKT, Dunlop, ZC Rubber, Hankook, Pirelli, Toyo, Sumitomo, Yokohama, Kumho, MRF, Apollo, Nokian, JKTyres, Cooper, Titan, Linglong, Triangle et al?

Bekaert has flagged off its first fleet of LNG-powered trucks in India in collaboration with GreenLine, the country’s leading provider of sustainable heavy trucking solutions. The joint initiative is aimed at supporting India’s vision for a gas-based economy and reducing the carbon footprint of road logistics.

The foundation of the collaboration with GreenLine is a mutual dedication to operational innovation and ESG standards. Bekaert has the infrastructure required to trial this effort in Chennai and Halol, with plans to expand following a six-month learning period, thanks to GreenLine's LNG ecosystem, which is supported by real-time telemetry and a smooth refuelling network. It is anticipated that each LNG truck will save up to 24 tonnes of CO₂ a year, making a significant contribution to Bekaert's targets of 65 percent of sales coming from sustainable sources and carbon net zero by 2050.

Dinesh Mukhedkar, Procurement Operations Lead – South Asia and Procurement Global Shared Service Centre Lead, said, “As part of our purpose, ‘Establishing the new possible’, and our ambition to lead in safe, smart and sustainable solutions, decarbonising logistics is an essential step. Heavy-duty transport contributes nearly 90 percent of emissions in Indian logistics. Switching to LNG helps reduce CO₂ by up to 30 percent and particulate matter by up to 91 percent compared to diesel. GreenLine’s mission and integrated support made them the ideal partner. Together, we are shaping a cleaner, more sustainable future for logistics in India.”

Trelleborg Tires is all prepped up to debut the ART1000, its first agricultural rubber track for high-powered machinery, at the upcoming Agrishow 2025, the largest agribusiness trade show in Latin America. The company will also display its TM150 CFO tyre, which is developed for a new generation of sprayers, along with a wide selection of products designed for modern farming. The event is scheduled to be held from 28 April to 2 May in Ribeirão Preto (SP), Brazil.

Trelleborg Tires enters the agricultural rubber track market with the ART1000, a tyre designed for high-horsepower machines. In addition to optimizing vehicle economy and offering additional strength and long-lasting durability, the ART1000 is engineered for remarkable adaptability and mobility of agricultural machinery in all operating circumstances. Its track design incorporates cutting-edge tread bars that reduce soil compaction, encouraging nutrient absorption and robust root development. In demanding high-pull applications, the high self-cleaning capability maximizes overall performance and lowers operating costs by improving ride quality and increasing traction. Even in the most demanding agricultural settings, ART1000's exceptional wear and cut resistance is ensured by its cutting-edge engineering and sophisticated rubber compounds.

The TM150 CFO series, which comes in sizes VF380/90R46 and has both VF (Very High Flexion) and CFO (Cyclic Field Operations) technology, is also making its debut in Brazil. CFO allows for greater load capacity during cyclic operations at up to 30 kmph when installed on contemporary, powerful sprayers. Because of its unique internal construction, the TM150 can operate at lower pressures, increasing its ground footprint, reducing soil compaction, and improving traction.

At Booth #E8b, Trelleborg will also display a range of high-performance tyre solutions including PneuTrac, a hybrid between a radial agricultural tyre and a track designed for smooth navigation in vineyards and orchards, the multi-award-winning TM1000 ProgressiveTraction tyre and the company’s patented agricultural TW rim profile for contemporary tractors, combines and harvesters.

Marcelo Natalini, President at Yokohama TWS South America, said, “Trelleborg Tires brings innovation from the soil up, delivering high-performing tyre solutions to boost productivity and protect their land. At Agrishow 2025, agri professionals will have the chance to connect with our tyre experts on site and see these technologies live, from the new ART1000 rubber track to our most advanced tyre ranges, designed to handle the challenges of next-generation machinery and modern field operations.”

Goodyear Tyre & Rubber is conducting a strategic review of the farm tyre business at its Indian subsidiary, signalling potential changes as the US manufacturer evaluates its global operations.

The Indian unit disclosed in a regulatory filing that its board has acknowledged communication from its American parent regarding the review. Goodyear will be examining "all strategic, operational and financial opportunities" related to the agricultural tyre business, according to the statement filed under SEBI disclosure requirements.

The Ohio-based tyre maker has not indicated any specific plans or timeline for the review. The company cautioned that there is "no assurance that the strategic review will result in the implementation of any transaction."

This move is part of Goodyear's broader efforts to optimise its global portfolio amid challenging market conditions in the automotive sector.

As part of a strategic effort to increase its presence in the region's premium original equipment (OE) market, Kumho Tire has confirmed its plans to establish its first tyre production facility in Europe by 2027.

The company has shortlisted Poland, Serbia and Portugal as possible locations for the plant, which is projected to need an investment of more than KRW1 trillion (USD 705 million). The decision is closely linked to Kumho’s ambition to strengthen its partnerships with European automakers and was revealed by Kumho Tire CEO during the South Korean premiere of Kumho's new Ecsta Sport tyre line.

Kumho has recently secured OE supply contracts with major brands such as Mercedes-Benz, BMW and Volkswagen Group. At the moment, Kumho runs eight tyre production plants in China, Vietnam, South Korea and the US. Its capacity to compete in the premium OE market, however, has come to be perceived as being constrained by the absence of a European production base. Through the benefits of local production, the new facility will improve response to European client requests, save freight costs and shorten delivery times, all of which will strengthen the company's partnerships.
