TIRED OF POOR TYRE KNOWLEDGE

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?

Remember success does not reward a lack of action. (TT)

Hankook Tire Launches National R&D Project To Develop Sustainable Tyre Manufacturing Technologies

Hankook Tire Launches National R&D Project To Develop Sustainable Tyre Manufacturing Technologies

Hankook Tire has formally launched a major national research initiative at its advanced Hankook Technodome facility in Daejeon. The kick-off gathering took place on 4 June to begin work on a project titled ‘Development of Tire Manufacturing Technologies Using Sustainable Materials’, which falls under the Ministry of Climate, Energy and Environment’s 2026 Environmental Technology Development Program.

The core objective of this undertaking is to accelerate South Korea’s transition to a circular economy by deriving high-grade recycled inputs from discarded tyres. Two parallel tracks of research involve creating premium reclaimed materials from waste rubber and establishing manufacturing processes that rely on sustainable components. Hankook Tire has been a driving force in this field since 2023, leading the domestic Tire-to-Tire consortium, and has already brought to market the iON GT, an electric vehicle tyre composed of over 70 percent sustainable content.

Participation in this government-backed programme allows Hankook to broaden its existing private sector work into a larger cooperative framework that includes universities, research bodies and industry partners. The company intends to strengthen its ability to adapt to evolving environmental rules while making its raw material supply chains more resilient. The project consortium brings together 11 entities, with M&B Green Earth acting as the lead institution alongside Kumho Petrochemical, HS Hyosung, Solvay, KRICT, KAIST and several other academic and technical organisations.

Hankook Tire ultimately targets the commercial release of next-generation, low-carbon tyres containing more than 85 percent sustainable materials and capable of cutting carbon emissions by over half. The project will also allow for large-scale validation of the domestic Tire-to-Tire circular model through product demonstrations and integrated performance assessments. Further demonstrating its commitment, the company recently attended the April launch of the Eco-design Forum, where industry players discussed compliance with the EU Ecodesign for Sustainable Products Regulation.

Bonhee Koo, Head of the R&D Innovation Division at Hankook Tire, said, “This national R&D project presents a meaningful opportunity to bring together the expertise of leading industry, academic and research institutions. Through close communication and collaboration among all participating organisations, we will strive to deliver tangible outcomes that contribute to strengthening competitiveness in the global market.”

Michelin Honours WWII Veterans With Normandy Trip For 82nd D-Day Anniversary

Michelin Honours WWII Veterans With Normandy Trip For 82nd D-Day Anniversary

Michelin North America, Inc. is participating once again in a special journey to transport World War II veterans to Normandy, France, in observance of the 82nd anniversary of D-Day. The initiative is carried out in collaboration with the Best Defense Foundation and Delta Air Lines, reflecting a unified effort to preserve the memory of veteran courage and sacrifice through direct, intergenerational experiences rather than solely through historical texts.

A charter flight carrying the veterans departed on 2 June, accompanied by caregivers and volunteers from the partner organisations. Over the course of a nine-day stay, the group will attend commemorative ceremonies and celebrations marking the anniversary. The Best Defense Foundation views the journey as not merely a commemoration but a meaningful opportunity for connection.

This year’s programme again includes students selected through the Best Defense Foundation’s NextGen initiative, who travel alongside the veterans as escorts and witnesses. From Omaha Beach to Pegasus Bridge and Carentan, the students will explore historic sites with those who lived through the events, ensuring that the stories of service members are passed on with authenticity and respect.

The collaboration among Michelin, the Best Defense Foundation and Delta Air Lines began in 2021 and has brought veterans back to France each year since the 78th anniversary in 2022. Michelin’s historic link to D-Day dates to spring 1944, when the 1939 Michelin Guide’s detailed maps were reprinted by Allied commanders to aid navigation in France. The company later produced additional maps for Allied advances, earning formal recognition from Allied Forces, and continues that legacy today through acts of remembrance and return.

Matthew Cabe, President and CEO, Michelin North America, Inc., said, “It is deeply meaningful and humbling for Michelin to stand alongside these veterans in Normandy. Supporting this initiative is one way we demonstrate our deep gratitude for these heroes and ensure the significance of their service is carried forward for generations to come.”

Bob Somers, Senior Vice President – Global Sales, Delta, said, “As we mark the fifth year of the Normandy Legacy Flight, we are reminded that carrying forward a legacy of this magnitude requires partners who share not only our values but a deep sense of purpose and responsibility. We are profoundly grateful for our partnership with Michelin, whose steadfast commitment and collaboration make this mission possible year after year. Together, we are honoured to pay tribute to our nation’s greatest heroes by preserving their legacy, honouring their sacrifice and ensuring their stories endure for generations to come.”

Donnie Edwards, Founder, Best Defense Foundation, said, “Michelin's commitment to this mission goes beyond sponsorship. It is a shared belief that the men and women who fought for our freedom deserve to be remembered, honoured and heard. Because of partners like Michelin, we are able to bring veterans back to the places that shaped history and ensure their stories live on in the people who will carry them forward.”
