The huge volume of data that can be collected from tyres is beyond most people’s comprehension, especially when most don’t even know they should be checking the tyre inflation pressures on a regular basis.

Tyre technology is advancing at an ever increasing rate. The demands of consumers on the products our industry produce are changing as vehicles evolve. The advent of electric vehicles (EV) has placed a series of demands on tyres that have not been previously experienced.

How will hydrogen-powered vehicles (HPV) vary from the EV requirements is an answer yet to be found. The intrusion of artificial intelligence (AI) into daily life is permeating faster than most can appreciate, and tyres are no different.

The huge volume of data that can be collected from tyres is beyond most people’s comprehension, especially when most don’t even know they should be checking the tyre inflation pressures on a regular basis.

Early Tyre Pressure Monitoring Systems (TPMS) generate reams of data. The systems used on F1 (Formula 1) cars and MotoGP bikes generate huge volumes, which is used to assist control of the vehicle. An example was relayed to me some years ago by a Moto2 race engineer who mentioned that when slip-streaming a bike (following literally nose to tail), it was observed that the temperature of the front tyre rose by up to five degrees

Celsius. I observe some of the artistic renditions of futuristic trucks and cars where tyres are completely enclosed by bodywork, ostensibly to aid aerodynamics. If the tyres don’t have a stream of cooling air, how do they dissipate the heat that is generated by the hysteresis a tyre experiences during operation? It is evident to me that many fall victim to what I call the Rumsfeld Rule; they don’t know what they don’t know, and worse still, they don’t know that they don’t know.

This could also be called the ‘First Rule of Tyre Technology’, just as I was taught the first law of computing, GIGO. If you have to ask, then you’re already a victim. The vast majority of the population don’t know much about tyres except that when they are flat, it’s a pain.

The fact that they entrust their lives to the humble servant we know as tyres on a daily basis without the basic knowledge is a serious concern to me. In the headlong race into technology, we’ve forgotten to bring the people along with us.

Social media is an example where most, nearly everyone, wants the fruit without having to prepare the soil, then grow the tree until it flowers, then wait for the fruit. ‘I want it now, I want it yesterday and stay tuned because the demands will all change’ (thanks Billy Connolly!) is all too common. The insidious outcome of this media is the ownership of the data, of what you buy, use, view, listen to, eat, where you visit is no longer yours. It is the big corporates that now own your data.

What does this have to do with tyres, I understand you ask. The humble tyre conveys us through our daily travels. It experiences a lot more than we do in that we don’t tread the pavements, or get hot or wet or get bounced over potholes on the road. The array of sensors now being developed for tyres are becoming the control centre of the automotive conveyances, be they fossil-fuelled, EV or HPVs.

What the tyre experiences is transferred into the vehicles control systems, which are then able to direct the motive forces to be applied at the appropriate rate. There is little use in having more brakes than there is traction available; that only results in a brake lock up, which destroys tyres and often results in a loss of control. ABS brakes are a prime defence of tyre lock ups. The tyre can collect the data which can determine your driving style, not only the route you have taken or the load you carry. So the automotive manufacturers will be able to use this data to tailor their solutions to you just as the social media concerns use algorithms to target content to you.

What is not quite as obvious as the data collection aspects is the environmental results of tyre use. Just as there are many unseen outcomes as a result of social media, there are outcomes that are largely unseen involved with tyre manufacture and use.

We go into a tyre shop to purchase tyres; it’s clean and bright or dark and dingy as a traditional tyre outlet or maybe something in-between. This experience tells us zero about how the tyre came into being and how it was landed in the store where you are purchasing it. The deeply technical and diverse agglomerations that are required to produce a tyre range from growing a tree (remember the fruit?) or drilling deep wells for oil, the mining of iron and other minerals to the production of complex chemical compounds used to create the rubbers.

The technology required to produce the single most complex item on today’s automotive machines is largely forgotten when standing in front of a range of tyres on offer. Unfortunately, a purchasing decision may be as basic as ‘what is the cheapest you have’ or preferably ‘what is the safest tyre you have’. As an industry, we’ve forgotten to educate the buying public on why a safe tyre is the item we should be purchasing. The race to the bottom to have low-cost items has yielded more than just cheap prices and substandard products.

Like most industries, there is a legacy of unwanted results; yes, the demise of discussion now we are staying glued to our phones instead of conversing.

Rubber, by its very nature, is a resilient compound that endures the abuse we throw at it when used as a tyre. Think about this for a moment: you purchase a new vehicle fitted with quality tyres, which we all know will be worn out when the tread is down to the tread depth indicators. What happens to the rubber that has worn away? Do you think about it? For those unfamiliar with on road motorsport such as F1 or MotoGP, you may not have heard of the term ‘tyre marbles’. These are chunks of the very sticky soft compound rubbers on tyres that are used for ultimate traction on a road circuit.

The marbles on a road racing circuit are quite obvious and are at the opposite end of the spectrum to the rubber particulates left on our streets and roads as our daily drives pass by. These rubber particulates (P2.5 is the smallest measurable in today’s systems) are particularly insidious as they permeate our environment.

The rubber dust is washed from the pavements when there is rain, dispersed through the drainage systems and then mixed into the outfall, be that a river and then ocean.

Dry dust particulates are dispersed by the winds into the soils. Microplastics ingress is a rising issue. Our technology (as an industry) is found wanting when the environmental aspects of product use is examined. No, I don’t have any answers except to consider magnetic levitation (which is feasible with examples operating) or matter transportation, which is off the planet for me. I raise the topic for consideration within the context of tyre technology. There is an immediate requirement for the recycling of tyres. Such projects, where the carbon black makes up about 40 percent of the recycling project product stream, seem to be an issue but are potentially feasible.

Tyres can be reused by retreading or repurposed in other manners; however, until the general public accept that tyres are more than a grudge purchase, then all the technology is only leading us further into the abyss.

Our industry needs the same energies as are applied to the technology employed to be used in education of our end users so they can grow to appreciate tyres just as we in the industry already do. As fire is a wonderful servant but a bad master, tyres too are wonderful servants but have serious outcomes if we continue to ignore them. Education is required. More technology is not necessarily the best answer.

As vehicle emissions regulations evolve, the lack of global uniformity is becoming a growing concern for OEMs and tyre manufacturers. With disparate standards across regions, companies are forced to navigate a complex regulatory maze, straining research and development and production resources. The shift towards electric mobility coupled with heightened focus on non-tailpipe emissions, such as tyre and brake abrasion, further amplifies the need for harmonised frameworks. Industry leaders including Audi’s Sebastian Gramstat argue that collaboration across borders and sectors is essential not just for compliance but for meaningful progress in sustainability and innovation.

Tyre regulations are rules and standards established to ensure that tyres used on vehicles meet safety, environmental and performance criteria. The impetus on new and updated regulations is also growing across regions to reduce pollution brought about by tyre abrasion, rolling noise etc.

The ECE R30, ECE R117, EU Tyre Labelling Regulation (2020/740), which is implemented within the European countries, or JIS Standards of Japan, CCC Certification of China, AIS 142 and BIS Certification of India and FMVSS, DOT Code and UTQG of the United States are different region-specific regulations aiming for a same outcome.

But the vastness of these regulations poses as a challenge for automobile OEMs and tyre makers alike as a lot of energy and resources have to be diverted within production and research and development lines to meet these standards.

Furthermore, the advancement of electric mobility and changes in vehicle dynamics are also slated to impose new regulations worldwide. Hence, the need for a uniform regulation has become a precondition.

Speaking to Tyre Trends on the need for uniform regulations, Dr Sebastian Gramstat, Senior Expert Development Brake System, Audi AG, averred, “Our company delivers products globally and having a unified standard is far more efficient than navigating a patchwork of regional requirements and regulations. Harmonisation brings clear operational and strategic advantages. That’s why we actively support and participate in standardisation and harmonisation working groups.”

“The European Union is involved through bodies such as the Joint Research Centre (JRC), but we also recognise the unique demands of other markets, particularly the US, where customer expectations can diverge significantly. These are often beyond the immediate scope of EU regulators. Our role is to help connect these dots by facilitating dialogue, sharing insights and contributing to building a global standard that benefits the entire ecosystem. We believe this collaborative approach is not only useful but essential to moving the industry forward,” he added.

The need for uniformity is exacerbated as OEMs and tyre makers continuously amp up research and development efforts to curb noise and air pollution from tyres. “Noise pollution, particulate matter or overall tyre wear remains a challenge. And the first step to tackle it is collaboration to develop a standardised method for accurately measuring tyre abrasion and wear. We are also working on such collaborations. Without reliable quantification, you can’t evaluate whether any mitigation measure is actually effective,” said Dr Gramstat.

He added, “This method needs to be robust, applicable across a wide range of real-world scenarios and globally accepted. That’s why we’re collaborating not only with industry partners and academia but also with regulatory authorities. This effort is taking place under the auspices of the United Nations and involves close coordination with national bodies, ministries and the European Commission. The goal is to ensure that the methodology we develop isn’t just technically sound but also internationally harmonised with Euro 7 regulations and integrated into UN regulations so it can be implemented consistently across Europe, North America, Asia and beyond.”

THE EURO 7

Tyres are a crucial component of overall vehicle design to the extent that many OEMs have dedicated in-house departments focused solely on tyre development, including Audi AG. While tyres aren’t developed in isolation, the process involves close collaboration with manufacturers to meet specific, often bespoke, requirements. These custom specifications ensure the tyre aligns with the car’s performance targets and regulatory demands including type approval.

When selecting a tyre, OEMs weigh multiple parameters; safety, performance and comfort are chief among them. But increasingly, attention is also given to sustainability and economy. Factors like tyre abrasion, longevity and fuel efficiency are becoming just as critical, particularly as regulatory frameworks begin to formalise such requirements.

Ultimately, the process involves balancing trade-offs. As Dr Gramstat put it, no tyre can deliver 100 percent on every metric. The goal is to find the best possible compromise – one that supports a premium product and meets both regulatory standards and consumer expectations.

Euro 7 is the upcoming EU vehicle emissions regulation set to take effect from 2025 for cars and vans and 2027 for trucks and buses. It introduces stricter limits on nitrogen oxides, carbon monoxide and particulate emissions, covering both combustion and electric vehicles.

It also regulates brake and tyre emissions and requires compliance under real driving conditions. It aims to cut air pollution, support the European Green Deal and standardise emission rules across vehicle types.

Alluding to whether the industry is ready to adopt the regulation, Dr Gramstat noted, “The industry is well-positioned for adoption. The European Tyre and Rim Technical Organisation (ETRTO) plays a central role in coordinating the efforts of tyre manufacturers across the continent, including legacy European brands and Asian manufacturers, with research and development and production facilities in Europe. Beyond Europe, we’re seeing strong international engagement. U.S. Tire Manufacturers Association (USTMA) is actively involved, and on the global standards side, ISO is working in parallel to develop the necessary technical frameworks. Stakeholders from China are also contributing significantly. This is no longer just a regional conversation but a truly global initiative. Experts from continents are collaborating to align regulatory, technical and industrial priorities, ensuring the tyre industry is prepared to meet the evolving demands of Euro 7 and beyond.”

Further outlining the impact of the regulation, he said, “Tyre manufacturers have largely operated under internal benchmarks for metrics like mileage and abrasion till date. Euro 7 represents a shift towards formal regulation, creating a harmonised framework that applies to the entire industry. This will undoubtedly influence existing design priorities. There’s a complex interplay between various tyre performance criteria such as wet grip, rolling resistance, noise and abrasion. Regulatory limits on one can impact the others, so the challenge will be to minimise trade-offs while maintaining overall performance. At this stage, it’s difficult to offer a one-size-fits-all answer. The impact will vary depending on vehicle type.”

REPLACEMENTS

Premium automobile OEMs like Audi have been using tyres from premium European tyre makers for decades. But as the status of Asian manufacturers changes, there might be room for such companies within the supply chain of premium car makers.

“At the end of the day, it’s not about the brand label but meeting the technical and performance specifications we define. Whether a supplier operates in the premium or high-volume segment, what matters is its ability to fulfil our requirements. If a manufacturer can meet those benchmarks and is willing to collaborate and co-develop with us, then they’re absolutely welcome. Competition in the supplier landscape is a positive force. It drives innovation, efficiency and ultimately better outcomes for the end consumer. We believe valuable ideas can come from any corner of the market and we’re open to partners who share our commitment to quality, performance and progress,” said Dr Gramstat.

He also acknowledged that there is a growing trend within the company to include tyres made from renewable and recycled materials. “The move towards sustainable materials is more than a marketing exercise. It’s becoming embedded in product development strategies across the industry. We’re already seeing recycled content being integrated into certain product lines, and the ambition from suppliers to scale this up is very real. What’s encouraging is that this isn’t limited to one-off pilot products. There’s genuine momentum towards making sustainability a core part of tyre manufacturing. For us, this aligns with our broader sustainability goals, and we see it as a critical area of innovation moving forward,” said Dr Gramstat.

However, the executive emphasised the importance of maintaining a balance too. According to him, sustainability is just one of several key factors in vehicle design while others include safety, comfort, performance and cost. He stressed that no single aspect, including sustainability, could come at the expense of another.

To meet these multi-dimensional goals, additional research and development efforts are required to create a product that meets safety and performance standards while also addressing environmental concerns. Economy remains a consideration as well. Internal research conducted under a European-funded project suggested that customers are, in fact, willing to pay a premium for more sustainable products but only up to a point. Price sensitivity remains a limiting factor.

Turning towards next-generation tyre concepts such as airless tyres, Dr Gramstat noted that innovative ideas like this were once viewed as distant possibilities but are now gaining traction. He cited the LEON-TI project from four years ago, in which airless tyre prototypes were first explored. Since then, similar concepts have been tested by various companies, including in pilot programmes for commercial delivery fleets in Asia.

Although these innovations show promise, particularly for reducing noise emissions and improving durability, they are still in advanced development stages.

THE FUTURE IS CHANGING

As the automotive industry moves towards electrification, the conversation around ‘zero-emission’ vehicles is evolving. Dr Gramstat acknowledged that while electric vehicles eliminate tailpipe emissions, other sources of pollution such as brake and tyre abrasion remain unaddressed in regulatory terms.

Currently, there are no standardised methods for measuring particulate emissions from these sources, but the industry is actively working on it. According to the executive, regulatory bodies and stakeholders are collaborating to develop measurement frameworks. Once these standards are in place, automakers will be able to quantify non-tailpipe emissions and provide a more accurate assessment of a vehicle’s overall environmental footprint.

The executive stressed that collaboration across the value chain is essential, especially between vehicle manufacturers and tyre companies. Such partnerships already exist within serial and advanced development efforts, including participation in the United Nations’ GRBP task force, which brings together manufacturers, tyre associations and regulators to advance tyre abrasion standards.

Weight reduction remains another key challenge. Automakers continue to look for ways to decrease vehicle mass but face constraints. Safety regulations now require more sensors and electronic control units (ECUs), which cumulatively increase vehicle weight. Although each component adds little individually, the growing number of sensors and accompanying wiring has a significant cumulative impact.

As for tyre development, the question of smart tyre was also addressed. While such technology offers valuable insights during research and development phases, Dr Gramstat expressed scepticism about its near-term viability for mass-market vehicles.

In a major step toward sustainable waste management, RPM Automotive Group has partnered with Fornnax to enhance its tyre recycling capabilities in Australia.

As part of the initiative, RPM has integrated Fornnax’s high-capacity SR-200 HD primary shredder into its operations, significantly improving recycling efficiency and material quality.

The collaboration supports RPM’s broader environmental goals and positions the company to process over 180 tonnes of used tyres weekly, with plans to scale beyond 300 tonnes. The move is expected to help RPM capture up to 5 percent of Australia’s national market share in tyre recycling.

Jignesh Kundaria, Director and CEO, Fornnax, said, "At Fornnax, we understand the urgency of addressing end-of-life tyre waste, not just in Australia but globally. The SR-200 HD Primary Shredder is designed for exceptional efficiency, enabling RPM to process vast quantities of discarded tyres while maintaining optimal operational performance. This collaboration showcases our dedication to providing our clients with the robust, high-performance solutions they need to excel in the circular economy."

RPM’s 3,500 sqmt facility not only boosts recycling output but also transforms waste tyres into rubber-based materials for road projects and industrial fuel. Leveraging its distribution network, the company aims to recycle up to 54,000 tonnes of tyres over five years.

The initiative aligns with Australia’s 2021 ban on tyre waste exports and underscores the urgent need for local recycling solutions.
