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!

The Yokohama Rubber Co., Ltd. has initiated the full-scale deployment of a proprietary generative artificial intelligence system, which became operational in August 2026. This advanced platform employs Retrieval-Augmented Generation (RAG) technology to sift through the company’s extensive internal repository of technical documentation. The primary objective is to furnish development engineers with rapid and precise access to critical information, thereby streamlining decision-making processes in areas such as material innovation and tyre design.

This system represents a significant expansion of Yokohama Rubber’s existing HAICoLab AI framework, first established in October 2020. While the company had previously introduced AI tools for predicting rubber properties, generating novel compounds and assisting mould design, a persistent challenge remained in efficiently navigating the vast collection of regulatory texts, manuals, reports and case studies that constitute essential domain knowledge. The new generative AI system was developed specifically to address this gap, enabling swift retrieval of pertinent data aligned with specific development goals.

In practice, engineers pose questions tailored to their project’s specific context and the AI searches for the most relevant information from internal records to formulate its answers. To further refine accuracy, an integrated AI agent interprets the user’s intent and autonomously cycles through planning, information retrieval and evaluation steps. Moreover, the system provides direct links to the original source documents, allowing staff to confirm the validity of the AI-generated responses and incorporate them into their analytical and strategic work. This functionality effectively integrates accumulated technical knowledge into the HAICoLab-driven development environment.

Concurrent with these technological advancements, Yokohama Rubber is actively cultivating digital transformation personnel proficient in utilising the HAICoLab platform. The company remains committed to enhancing the system’s capabilities and leveraging its internal data and intellectual assets to foster the creation of innovative products, processes and services moving forward.

Linglong Tire has expanded its European summer tyre portfolio for light commercial vehicles with two new offerings under its subsidiary brands, Leao Tire and Crosswind Tire. Following the spring introduction of the Linglong Dura Master Van, the company has now launched the Crosswind Dura Peak Van and the Leao Nova-Force Van 2. This marks Crosswind's first entry into the summer van tyre segment, while the Nova-Force Van 2 succeeds its well-regarded predecessor.

Engineered specifically for vans, motorhomes and light trucks, both tyres emphasise durability, fuel efficiency and enhanced driving performance. Their new construction integrates optimised tread patterns and wider footprints to reduce wear and extend mileage. An innovative silica-based compound lowers rolling resistance for significant cost savings, a critical factor for commercial operators. The reinforced carcass supports heavy loads, while advanced sipe technology, combined with the tread compound, shortens wet braking distances and improves handling on both wet and dry surfaces.

Manufactured exclusively at Linglong's advanced facility in Zrenjanin, Serbia, each tyre line is available in 29 sizes ranging from 12 to 17 inches, with orders now being accepted. Development took place at the European Development Center in Hannover, with validation testing conducted at the Idiada circuit in Spain and the group's Sino Asia proving ground in China. These strategic choices underscore Linglong's commitment to European-quality engineering and rigorous performance standards for its commercial vehicle offerings.

Looking ahead, Linglong plans to complete the van tyre ranges for both Crosswind and Leao Tire with the introduction of new winter and all-season tread patterns scheduled for late 2026. This upcoming expansion will further solidify the group's comprehensive year-round coverage in the light commercial vehicle segment across its brand portfolio.

Wencheng Liu, Head of Product Management, Linglong Tire, said, "With the new Crosswind and Leao van tyres, we are expanding our range in the field of light commercial vehicles and offering a high-performance solution for both businesses and private households. Both tyres combine high mileage with safety and efficiency – crucial factors for cost-conscious families and entrepreneurs who use their vehicles on a daily basis."

India’s tyre exports rose 16 percent year on year to INR 77 billion in the first quarter of FY2026–27, despite geopolitical uncertainty, supply-chain disruptions and elevated input and logistics costs, according to the Automotive Tyre Manufacturers’ Association (ATMA), citing data from the Ministry of Commerce.

The April–June performance builds on a record export value of INR 273.12 billion in FY2025–26, indicating sustained external demand for Indian-manufactured tyres.

Passenger car radial (PCR) tyres led the growth, with export value increasing 21 percent during the quarter.

Arun Mammen, Chairman of ATMA, said: “The significant growth in tyre exports during the first quarter represents a strong start to the new financial year. It reflects the growing acceptance of Indian-manufactured tyres across discerning global markets and the sustained investments made by the industry in technology, capacity, product development and quality.”

Europe was a key growth driver, with exports to the region rising 25 percent to INR 30.03 billion in the quarter, accounting for nearly 40 percent of total tyre exports. The US remained the single largest export destination, contributing 16 percent of overall export value. Indian tyres are exported to more than 170 countries.

India’s global presence is also supported by tyres supplied as original equipment on vehicles manufactured domestically and exported worldwide.

ATMA said improved market access through trade agreements and supportive export policies could help the industry sustain momentum and strengthen India’s position as a global tyre manufacturing and export hub.

The Indian Rubber Materials Research Institute (IRMRI) recently announced the appointment of Professor (Dr) Abhijit Bandyopadhyay as its new Director. In a tete-a-tete with Tyre Trends, he delves into his top priorities and IRMRI’s roadmap under his leadership.

What will be your top priorities as the new director of IRMRI?

I have a list of four priorities. The first is to transform IRMRI from a testing and certification centre into an innovation hub that integrates research, technology development, scale-up engineering, innovation and commercialisation for the tyre and non-tyre rubber industries. The second priority is developing technologies for EV tyres. While automakers are using lightweight polymer composites and foams to offset battery weight, advancing EV tyre technology will remain a key focus.

Thirdly, to undertake autonomous research that benefits industry beyond traditional rubber compounds, covering plastics, rubber-plastic blends, advanced polymer systems and other emerging materials. Finally, internationalise IRMRI by establishing MoUs with global industries and academic institutions.

Sustainability and circularity are becoming central themes across industries. How do they fit into your vision for IRMRI?

Sustainability should not be viewed as a separate objective; it must be embedded in every project we undertake. Every technology we develop should inherently follow sustainable principles. The introduction of Extended Producer Responsibility (EPR) has fundamentally changed the tyre industry’s responsibilities by making manufacturers accountable for the waste generated by their products.

This naturally increases the importance of reclaimed rubber, rubber crumb, recycling technologies and broader circular economy practices. Today, applications for reclaimed materials remain limited and expanding their use will become an important research area.

How will you strengthen collaboration between IRMRI, academia and industry?

IRMRI has always supported industry through its testing services but its contribution to research and development can become much stronger. At present, academia and industry operate with very different priorities. IRMRI is uniquely positioned to bridge this gap because it already has advanced facilities in Chennai, Thane and the Eastern Centre, with new centres coming up in Tripura and Delhi.

Building on existing collaborations at the Thane Centre, IRMRI should expand partnerships with universities, IITs and industry beyond rubber technology into areas such as mechanical engineering, machine design, sustainable rubber processing, simulation, modelling, artificial intelligence and other multidisciplinary fields to strengthen both its research capabilities and national stature.

What are the biggest challenges facing India’s rubber and tyre industry today?

The industry’s biggest challenge is sustainability, particularly recycling, devulcanisation and compliance with EPR. While significant progress has been made in developing rubber and polymer products across numerous industries, recycling remains a major technological hurdle.

The same challenge extends beyond rubber to composite materials. Although material development has advanced considerably, achieving efficient, commercially viable recyclability remains one of the industry’s greatest unresolved problems.

What do you expect to be the biggest challenges in your new role at IRMRI?

I have worked closely with industry for the past 16 years and almost all of my current research projects are industry-sponsored. I understand industrial expectations, priorities and ways of working, so adapting to the industry itself will not be difficult.

The real challenge will be transforming IRMRI from a testing institute into a research and innovation institute. Achieving this will require a clear roadmap, well-designed policies and systematic implementation with some trial and error along the way.

How do you see AI and digital technologies accelerating rubber materials research?

AI, simulation, modelling and digital engineering will become integral parts of IRMRI’s future development strategy rather than standalone initiatives. Artificial intelligence is fundamentally a form of data science. It involves developing computational models and predictive systems that help researchers analyse data more intelligently and efficiently.

Computation, simulation and modelling are becoming increasingly important. The tyre industry already relies heavily on these tools because modern tyre development would be almost impossible without them. However, the non-tyre rubber industry has not yet adopted them to the same extent. Simulation and modelling also contribute engineering efficiency, reducing development costs, optimise manpower deployment and enable better product design before physical prototypes are built.

How can IRMRI strengthen its testing capabilities to meet future industry requirements?

IRMRI already has strong testing facilities for existing technologies, but the rapid growth of electric vehicles makes specialised EV tyre testing an important priority.

We also need to evaluate whether current testing protocols adequately assess EV-specific requirements such as acoustic performance, vibration characteristics and other parameters beyond rolling resistance. Where gaps exist, IRMRI will develop new testing methodologies and standards tailored to EV tyres.

What emerging technologies and materials should IRMRI focus on in the coming years?

Sustainability and next-generation materials must be major priorities. As bio-composites and natural-material-based rubber products gain importance, standardised testing methods for many rubber-polymer bio-composites are still lacking. Developing reliable performance evaluation standards for these materials while strengthening capabilities in recycling, devulcanisation and circular economy technologies will help Indian manufacturers meet global quality standards.

Material innovations, particularly in solution-grade Styrene-Butadiene Rubber (SBR), will also require advanced testing, reinforcing IRMRI’s vision of becoming an innovation-driven institute.

How can IRMRI help Indian manufacturers meet global quality standards?

Helping Indian manufacturers meet increasingly demanding global quality and performance standards begins with addressing the industry’s biggest technological challenges, which is recycling, devulcanisation and circular economy requirements. If IRMRI can develop technologies in these areas, it will benefit both the rubber and non-rubber industries.

As an NABL-accredited institution, IRMRI also has a unique advantage over most universities, whose testing and certifications, while technically credible, are generally not accepted for commercial compliance. Now that IRMRI has been recognised as an institute, it will strengthen its independent certification capabilities and establish itself as a nationally and internationally respected authority for testing and certification.

Does India need stronger collaborative testing programmes?

Yes. India needs a more structured ecosystem that brings together research institutes, OEMs, raw material suppliers, manufacturers, universities and IITs throughout testing and product development. IRMRI should become the platform that connects academia’s knowledge-driven research with industry’s application- and product-oriented approach, accelerating innovation.

Internationally, this model has proven successful through industry-sponsored academic programmes that create a continuous pipeline of research, skilled talent and commercial innovation. India has some examples of such collaborations, but they remain scattered and should be expanded significantly.

How do you plan to change the industry’s perception of IRMRI?

One of my biggest objectives is to fundamentally change how both the tyre and non-tyre industries perceive IRMRI. Today, the institute is primarily viewed as a testing laboratory. Testing will always remain an essential function, but I want IRMRI to be recognised as much more than that.

My vision is for IRMRI to become an innovation hub where research, technology development, product innovation, industrial problem-solving, scale-up engineering, commercialisation, multidisciplinary collaboration and advanced materials research all come together. Changing that perception will take time, but we will build that bridge eventually.

What opportunities do you see for retreading technology?

Retreading has enormous potential but also significant technical challenges because it involves bonding a new tread to an already vulcanised tyre. While unvulcanised rubber is naturally tacky, vulcanisation removes this property, making two vulcanised surfaces difficult to bond.

Strong adhesion requires roughening both surfaces for mechanical anchorage followed by specialised adhesives and carefully controlled processing. Since India’s retreading industry remains fragmented, advancing retreading technology will be a key focus, particularly for its sustainability and resource conservation benefits.

Looking ahead, what will define the success of IRMRI?

Success, in my view, will not be measured by the number of tests conducted or certifications issued but by whether IRMRI becomes an innovation-driven institute. That means undertaking autonomous research, developing industry-focused technologies, strengthening academia-industry collaboration and more.

Indian manufacturers compete globally. Ultimately, I want IRMRI to be recognised not just as a testing centre but as one of India’s leading innovation hubs for rubber, polymers, advanced materials and sustainable industrial technologies.
