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)

Goodyear executed its largest-ever endurance operation at the 24 Hours of Le Mans, a feat defined by 188,747 kilometres driven, 377.5 million wheel revolutions, and 44 cars competing across the LMGT3 and LMP2 classes. The Goodyear Racing Eagle tyres delivered relentless performance, supported by over 120 experts and a stock of 8,000 tyres that sustained racing throughout the entire week.

The tyres' exceptional consistency allowed teams to extend stint lengths significantly, saving precious time during pit stops. Most LMGT3 squads completed four stints, or forty laps, before changing rubber, while LMP2 entries routinely managed five. One LMP2 team notably kept a single set for 56 laps, covering 761 kilometres, a distance comparable to travelling from Le Mans to Monaco.

Pace did not diminish despite the high mileage, with the fastest LMGT3 car posting a 100-lap average 1.2 seconds quicker per lap than the previous year, marking the fastest Le Mans of the LMGT3 era. Goodyear’s off-track presence was equally robust, featuring the Goodyear Blimp, a new grandstand, a popular fan activation, a museum collaboration and the introduction of the Goodyear Passerelle.

Ahead of the race, Goodyear reaffirmed its commitment to LMGT3 through a joint announcement with the FIA and ACO, extending its exclusive supply into a fourth season in 2027 with a new tyre composed of 66 percent sustainable materials. The WEC now moves to the 6 Hours of São Paulo on 12 July, though many Le Mans teams will first compete at the European Le Mans Series’ 4 Hours of Imola on 5 July.

Stephen Bickley, Goodyear Endurance Program Manager, said, “When you look at the distances covered without compromising on pace, it underlines the consistency and reliability of our Goodyear Racing Eagle tyres throughout one of the toughest races in the world. It was a special Le Mans for us, felt through our fan activation, partnership renewal and icons old and new at – and above – the circuit.”

The Tire Industry Project (TIP) has initiated a pilot study in collaboration with the Greater Paris Sanitation Authority (SIAAP) and the sustainability consultancy ERM to assess the potential of wastewater treatment plants to remove tyre and road wear particles. The research is being conducted at the Valenton wastewater treatment facility near Paris, which ranks as Europe’s second-largest plant and features advanced treatment technologies representative of modern municipal systems. This investigation is scheduled to continue through 2026.

In numerous urban centres globally, stormwater and road runoff are channelled into wastewater systems prior to being discharged into natural waterways. A clearer understanding of how effectively these treatment processes capture TRWP could guide the broader adoption of optimised wastewater management practices. Currently, systematic data quantifying the removal of these particles within treatment plants remains scarce, and this project aims to generate comprehensive, end-to-end evidence to bridge that knowledge deficit.

The study represents TIP’s first real-world application of a priority mitigation strategy identified in its white paper on addressing tire and road wear particles. Over the coming months, researchers will collect and analyse samples from key stages of the Valenton plant’s treatment cycle using advanced pyrolysis gas chromatography-mass spectrometry. The findings are expected to estimate the total removal efficiency across the entire process and will be submitted to a scientific journal, with publication anticipated in early 2027.

The scientific understanding of TRWP is complicated by a lack of standardised methodologies, the variable nature of the particles and their transformation products, and the diverse environmental pathways they traverse. In response, TIP and its member companies have committed to advancing research on quantification, characterisation, environmental migration and potential impacts while collaborating with value-chain stakeholders to support science-based interventions. A 2024 TIP publication reviewed over 50 mitigation measures and prioritised nine based on upstream and downstream potential, employing a prevention, containment and removal framework.

That review also concluded that no single measure has been proven effective specifically for TRWP and that on-ground validation is essential. Moreover, the paper stressed that no universal solution exists, requiring coordinated, large-scale implementation across multiple actors, including the tyre, road construction and automotive sectors, as well as municipal authorities, academia and other public and private entities. The Valenton pilot thus marks TIP’s inaugural effort to test wastewater management’s real-world efficacy, uniting diverse stakeholders from both the public and private sectors in this critical research.

Larisa Kryachkova, Executive Director, TIP, said, “This pilot is an important step in going beyond understanding the subject in the laboratory to field-based evidence. We expect to identify best practices that can be applied far beyond this project, supporting TIP’s ambition to support science-based mitigation.”

Sabrina Guérin, Head of Innovation Department, SIAAP, said, “As the public authority responsible for wastewater treatment in the Paris region, SIAAP is committed to emerging science that protects waterways. By taking part in this TIP study, we will gain an early, science-based view of TRWP movement in solid waste. The findings can help inform and accompany future treatment planning and readiness for upcoming regulatory requirements.”
