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)

New research findings from a doctoral dissertation by Dr.-Ing. Sebastian Bogdahn examine how end-of-life tyres can yield high-quality recovered carbon black (rCB) through pyrolysis while delivering substantial environmental benefits. The work, titled ‘Production and Environmental Assessment of High-Quality Carbonaceous Materials from End-of-Life Tyre Pyrolysis’, was presented in condensed form at an AZuR Chemical Recycling Project Group meeting in Dillingen/Saar on 1 October 2026.

The dissertation tackles how end-of-life tyres can be recovered and recycled to maximise their value. Pyrolysis is identified as a complementary technology that helps close recycling gaps in the circular economy and offers an alternative to fossil-based carbon black, a material that plays a crucial role in determining tyre properties.

In the pyrolysis process, rubber granules from processed tyres undergo thermal decomposition without oxygen, producing three main streams: solid rCB, tyre pyrolysis oil and pyrolysis gas. Previous evaluations of such technologies often separated technical and environmental perspectives, relied on secondary data and lacked standardised methodologies, making findings difficult to compare.

Bogdahn overcomes these limitations by integrating a technology-specific process model with a detailed life cycle assessment model. This combination enables a scientifically robust environmental evaluation of pyrolysis and its secondary raw materials using reliable primary data. A central component is a process model that mathematically describes material conversion by combining reaction kinetics, reactor behaviour and mass and energy balances.

Starting with laboratory-scale experiments, the model was scaled up and validated using a pilot-scale rotary kiln at the Institute of TH Köln. Comprehensive laboratory analyses of feedstocks and products supported development and validation. Optimal conditions for the investigated system were found at 650 degrees Celsius with a residence time of about one hour, achieving complete material conversion and high-quality recovered carbon black. Product distribution was roughly 40 percent rCB, 37 percent TPO and 23 percent pyrolysis gas by weight.

Using validated primary data, Bogdahn conducted a comprehensive environmental assessment and developed a methodological matrix covering relevant standards and guidelines to address inconsistent approaches. In the rotary kiln baseline scenario, one metric tonne of recovered carbon black results in a global warming potential over 100 years of about 918 kilogrammes of carbon dioxide equivalents, compared with the International Carbon Black Association’s global industry average of 3,910 kilogrammes for conventional fossil-based carbon black, a reduction of approximately 77 percent. Even after a quality adjustment for lower carbon content, the reduction remains about 70 percent. The study followed ISO 14067 and underwent independent external critical review under ISO 14071, also covering TPO and sustainable carbon black.

Further improvements remain possible. Emissions mainly stem from electricity consumption and gas combustion, with rCB processing accounting for about 44 percent, pyrolysis gas cleaning and combustion about 36 percent and tyre shredding about 19 percent. Sensitivity analysis confirms that renewable electricity offers substantial additional greenhouse gas reductions, reinforcing that a circular economy achieves genuine sustainability only when powered by renewable energy. Enhancing material quality through demineralisation and activation could enable higher substitution rates for fossil-based carbon black.

A central conclusion extends beyond pyrolysis itself. Raw materials, tyre manufacturing, the use phase and recovery pathways form an interconnected system spanning the entire tyre life cycle, closely linked to the carbon black, chemical, steel and energy sectors. Achieving circularity requires collaboration across systems and industries, along with greater methodological harmonisation and stronger integration of industrial value chains. The AZuR network’s work reflects this need, recognising that extended tyre use, repair, regrooving, retreading, mechanical recycling and appropriate chemical recycling must all function as interconnected elements of the value chain.

Tyres Europe, as part of a coalition of 10 European associations representing consumers and automotive and mobility service providers, has issued a joint press release welcoming the latest CARUSO Connected Vehicle Field Test assessing the EU Data Act’s implementation across 29 major vehicle manufacturer groups. The findings confirm the legislation established important principles for accessing vehicle-generated data and encouraged some manufacturers to engage for the first time. One year on, however, the framework remains insufficient alone to enable a competitive, innovative connected mobility market.

Covering 15 automotive use cases across 28 vehicle manufacturer groups, the study concludes that while data access has improved, conditions for competitive, scalable, multi-brand services are still lacking. Access remains fragmented, inconsistent and often commercially or technically impractical across the car parc. Limited third-party access, differences in data scope, quality and coverage, and restrictive commercial terms continue to undermine the business case for innovative services. Genuine multi-brand development remains unattainable, preventing consumers and businesses from fully benefiting from connected mobility.

For many manufacturers, implementation has become a compliance exercise rather than a genuine effort to enable market access. Independent providers face limited datasets, restrictive terms, manual approvals, manufacturer-specific consent mechanisms and inconsistent technical solutions. Such approaches may satisfy the Data Act’s broadly defined obligations but are incompatible with the real-time, automated access modern digital services require.

Strong enforcement matters. Manufacturers respond faster where national authorities investigate complaints and apply enforcement mechanisms. Without consistent, harmonised, proactive enforcement across the European Union, Data Act rights risk remaining largely theoretical for a significant share of Europe’s vehicle fleet.

The coalition urges European Union institutions and Member States to enforce the Data Act consistently, issue clear guidance on fair, reasonable and cost-based compensation and use forthcoming reviews to reinforce rather than weaken it. Dedicated automotive legislation should establish common access conditions, interoperability requirements, initial technical and data delivery standards and safeguards against discrimination. Effective access must cover vehicle-generated data and the in-vehicle functions and resources needed to develop, scale and deliver digital mobility services, enabling fair competition, growth and investment.

According to the coalition, the Data Act was an important first step, but horizontal legislation alone cannot create a workable multi-brand market. Implementation varies widely: of 28 manufacturers, nine (32 percent) have barely implemented the Act; 18 (64 percent) lack adequate third-party pricing; 18 (64 percent) lack adequate data provision; and 19 (68 percent) lack an adequate API solution. Sixteen manufacturers (57 percent) enable none of the use cases, while only nine support the most feasible ones. Without stronger enforcement and dedicated automotive legislation, Europe will fall short of its innovation, consumer choice and fair competition ambitions.

CEAT reported a 26 percent year-on-year increase in consolidated revenue to INR 47.62 billion in the second quarter of the 2026-27 financial year, while net profit stood at INR 1.12 billion as higher raw material costs continued to weigh on the tyre maker.

The company’s consolidated earnings before interest, tax, depreciation and amortisation (EBITDA) margin was 9.5 percent, according to its unaudited results for the quarter ended 30 September.

Arnab Banerjee, Managing Director and Chief Executive, said revenue growth was supported by premium segments across business units. He added that the conflict in West Asia had kept raw material costs high, prompting the company to tighten cost controls.

CEAT expects to deliver double-digit revenue growth in the second half of the financial year, alongside further price increases, Banerjee said.

On a standalone basis, revenue rose 23 percent year on year to INR 45.48 billion. EBITDA margin was 10.14 percent, while net profit reached INR 1.64 billion.

Kumar Subbiah, Chief Financial Officer, said commodity costs were expected to remain elevated in the third quarter. The company would continue to pursue measured price increases and improve its product mix to manage cost pressures.

Subbiah said debt increased during the quarter, largely because of capital expenditure of close to INR 4.9 billion to expand capacity in areas with high utilisation, as well as dividend payments.

He added that CEAT would maintain financial discipline while investing to meet demand and support profitable growth.
