Tyre research and development  racing groups  are working vigorously on new combinations of hardeners, fillers, polymers or fine-tuning design parameters. They are eagerly looking for ways to improve grip, durability, handling and comfort in wet or dry conditions. They customise tyres for particular weather and track conditions. Each of their design logic is different. On race tracks, the tyres operate under extreme conditions that cannot be fully simulated on indoor test drums. Therefore, the development of the tyre is always complemented by the actual result of the route. They bring dozens of different specification tyres to the track for a single sponsored car. Regular road tyres are very different from racing tyres. However, tyre manufacturers are still considering or applying a combination of new race specifications to improve rolling resistance, increase grip or maximise durability.

Motorsport is in many ways the ultimate R&D programme for the tyre companies, and they spend heavy budgets on such programmes. Thus, they strictly defend their intellectual property. They pick up all the pieces of rubber that were torn off and left on the track to make sure they have all the tyres again. They work until they are sure they have all the parts.

The racing car reaches a top speed of up to 400 kmph, and the tyre has to withstand temperatures of up to 240 degree Celsius  at the point. Or on slower, more twisty tracks, a softer tyre offers more grip, but it still reaches very high working temperatures. Each tyre specification consists of the owner’s technology and each is worth protecting its intellectual property. There are examples where a company threatens racing teams with a fine of one million euros for every tyre lost. Tyre companies don’t want to leave any chance of technology leakage. Every company is very keen to collect its racing tyres before it leaves the circuit. The tyres later are cut off in small pieces and sent to incinerating areas.

But anyway, when all the racing teams arrive on the circuit with hundreds of tyres, they take the risk of leaking some IP information.

The Ultra High Performance (UHP) tyres must have sufficient speed capability along with wet and dry grip performance, which are reflections of some rally tyre specifications

Racing tyres are racers’ best friends and can meet the demands of extreme conditions. Tyres are generally differentiated into ‘soft’, ‘medium’ and ‘hard’. A softer tyre is faster and safer in rallies but has a shorter life, while the hard-tread tyre provides a longer life. On the other hand, there are commercially available rally tyres with different tread compounds belonging to the major brands of rally tyres. Compounds for uphill and wet use for lighter and heavier cars, slick compound for lighter cars, softer and harder slick compound for lighter rally, sprint and endurance, Soft-Medium- Ultra-Very Hard Compound for Slick or Classic, Hard- Soft Compound for Sports Cars, Very Soft-Soft-Medium-Hard GT Hill Climb Blend, Soft Compound for Rally-Cross Applications  are such examples.

When we talk about UHP as a car, it is equipped with upgrades such as a more powerful engine, more powerful brakes, sports suspension and UHP tyres, but especially the body style that shares the base model. Therefore, UHP tyres must have sufficient speed capability along with wet and dry grip performance. Rolling resistance is a leap back and opposes the high grip rate of performance tyres. All these facts are brought together, thanks to the hard work and experience of people in R&D.

Motorsport is an important technological tool for the automotive industry. So it does open horizons to tyre designers.

The rubber of a tyre is viscoelastic; it deforms and adapts to the texture of the road surface as it rolls over it. This asymmetric deformation of the rubber generates a reaction force that prevents drift. In other words, it generates a frictional force which is defined as a grip. The coefficient of friction between the surfaces of the tyre and the track depends mainly on the behaviour of the tyre’s rubber. Tyre hysteresis is a critical factor in generating grip.

Molecular interactions occur at the interface between the tyre rubber and the road surface, which generates grip. The molecular chains of rubber follow this cycle of stretching and breaking, which creates viscoelastic work. This work effectively multiplies the amount of bond energy by a factor that depends on the temperature of the rubber and the speed of rolling. Tyre grip has heretofore been referred to as ‘molecular grip’, which also means why a tyre deposits rubber on a racing track depending on the rubber’s hysteresis, deformability and viscosity. These three parameters are consisting three corners of a triangle. Stretching only one corner to maximise performance does not work.

In many ways, motorsport is part of the ultimate R&D programme. Every aspect of a modern vehicle already part of everyday life has been built and generated with specific technology business development programmes.

Motorsport is an important technological tool for the automotive industry. It is in motorsport that automotive technology evolves. The same goes for racing vehicle tyres that run under such vehicles and are superior in materials and structures, which will later suit the next generation UHP tyres.

In the early days of the automobile, rallies were a kind of enthusiasm full of adrenaline.  ‘Motorsport’ organisations are a convenient way to test attained abilities and stimulate technology in science and people’s lives. Vehicle dynamics is one of the critical issues in the present century and the last century. Much trial and error have been carried out in recent years to achieve speed, safety and transport capacity.

Today’s vehicles are full of sensors for different functions to alert drivers about faulty parts. Pressure monitoring systems in tyres are popular the EU . Tyre Pressure Monitoring System (TPMS) became mandatory for all M1 vehicle classes after 1 November 2014. Automated Tyre Monitoring and Inflation System can ensure adequate tyre pressure to meet better handling requirements, which is possible with today’s technology and quite suitable for motorsport vehicles. The tyre, as the most important part of vehicles, has varying characteristics with its viscoelastic structure. The automated tyre monitoring and inflation system will reduce the effect of variance on the tyres.

What are the breakthroughs in motorsport events today?

Motorsport by virtual reality could be fully utilised in the design and upgrading of vehicles. Different vehicle models, weather conditions, tyres and situations can be simulated with minimum stress and fun, and this can encourage radical innovations to scale down with significant money savings.

What about self-driving car races?

The Roborace championships with fully autonomous car races have already started in 2019. Self-driving cars on the road are an incredible achievement, thanks to complex algorithms. It learns and reacts to the racing environment and has faster ‘reflexes’ than any human driver capable of making predictions. It is said that a prototype autonomous vehicle generates 100 TB of data a day, which is open to different skills for younger generations.

But either way, the challenges of motorsport will need talented engineers to harness the cutting edge technology of tomorrow’s motorsport. (TT)

With the rise of electric vehicles reducing exhaust emissions, attention is shifting to non-exhaust emission like Tyre and Road Wear Particles (TRWP). These microscopic particles, generated from tyre and road surface friction, are a growing environmental concern and will be addressed in the upcoming Euro 7 emissions standard. To tackle this challenge, Nynas has joined a major research consortium coordinated by the Royal Institute of Technology (KTH), alongside Volvo Cars, Scania and the Karolinska Institute.

The project aims to close a significant scientific knowledge gap by thoroughly investigating the formation, characteristics and environmental impact of TRWP. Nynas contributes a unique dual perspective to this interdisciplinary effort, bringing deep expertise in both tyre rubber compounds and bitumen-based road materials. Pär Nyman, Technical Manager – Tyre & Chemical Industries, Nynas, represents the company in the project alongside the company’s Chief Scientist, Dr Xiaohu Lu, who brings extensive expertise in bitumen and asphalt to the collaboration. A key focus will be understanding how different materials contribute to wear mechanisms.

The research scope extends beyond particle analysis to include measuring the rolling resistance of various tyre and bitumen combinations, a parameter directly linked to vehicle energy efficiency and greenhouse gas emissions. By uniting industry and academia, this collaboration is poised to drive innovation and set new benchmarks in sustainable mobility research.

Pär Nyman, Technical Manager – Tyre & Chemical Industries, Nynas, said, “While Sweden lacks domestic tyre manufacturers, Nynas' research capabilities fill that gap by providing foundational insight into the chemistry and physics behind TRWP generation. Nynas' rubber and asphalt labs are at the heart of this contribution. One of the core insights driving this initiative is that wear particles cannot be fully understood by analysing tyres or roads in isolation. It's the interaction – the system – that matters. By studying both tyre composition and road structure, the project aims to develop a holistic view of TRWP formation, dispersion and toxicity. At Nynas, we are excited to contribute our unique knowledge of materials to help solve an important challenge for both the environment and human health. Through collaboration and scientific inquiry, we aim to pave the way for cleaner roads and cleaner air – one particle at a time.”

Ecolomondo Corporation, a Canadian developer of sustainable tyre recycling technology, has released its unaudited financial results for the second quarter ending 30 June 2025. The period was marked by significant progress in commercialising its Hawkesbury thermal decomposition facility, particularly within the recovered carbon black (rCB) department. A major milestone was reached with the installation and commissioning of new milling equipment, a critical step for the plant to achieve full operational capacity, as rCB is its primary revenue generator.

Following the quarter's end, the company's main rCB client formally approved the product quality, leading to five consecutive purchase orders for multiple truckloads delivered between July and August. A separate US-based customer has also approved the rCB quality, with bulk purchase orders anticipated imminently.

Financially, Ecolomondo secured USD 1.5 million through private placements and finalised a significant agreement with Export Development Canada (EDC). This arrangement provides a temporary postponement of principal and interest payments on three existing loans, improving the company's working capital and investor confidence. This debt modification resulted in a gain of USD 2,495,209, which contributed to a reported net profit of USD 1,452,712, for the quarter, despite an operating loss, which stood at USD 1,042,497 for the quarter, compared to USD 443,418 for the same period of 2024.

Revenue saw substantial growth, increasing by 212 percent to USD 395,149 compared to the same period in 2024, driven by product sales and tipping fees at the Hawkesbury plant. Capital expenditures for the Hawkesbury TDP turnkey facility totalled USD 51,358,723 after accounting for depreciation, while the company’s cash and cash equivalents stood at USD 1,508,645. Over the coming 12 months, Ecolomondo anticipates utilising an additional USD 2.0 million, which will be primarily allocated to covering ongoing working capital requirements and essential capital purchases for the Hawkesbury facility.

The company also advanced its global expansion strategy, signing a definitive agreement with ARESOL, a renewable energy group, to construct four turnkey recycling facilities in the European Union. The first plant is planned for Valencia, Spain. At its Annual General Meeting, all management proposals were unanimously adopted by shareholders.

The European Tyre and Rubber Manufacturers’ Association (ETRMA), alongside 13 other European business organisations, has signed a Joint Statement urging the European Commission to ensure a strong and ambitious implementation of the Data Act.

The coalition, including numerous SMEs and Small Mid-Caps from the digital and industrial sectors of European companies, has urged the European Commission to uphold the regulation against pressure to dilute its core provisions, identifying it as a crucial framework for unlocking industrial data across the EU economy. The signatories contend that a robust implementation is vital for fostering a competitive market and unleashing innovation, particularly for smaller businesses.

The coalition highlights the Act’s benefits, which include empowering SMEs with data portability rights, protecting them from unfair contractual terms and mandating that data sharing occurs on fair, reasonable and non-discriminatory (FRAND) terms. A key provision requires cloud providers to facilitate switching through open standards, combating vendor lock-in. The statement expresses concern that lobbying efforts for delayed enforcement, weaker interoperability definitions and reliance on global standards without fairness guarantees threaten to undermine these objectives.

For the Data Act to be effective, the coalition insists on full implementation to open data markets to genuine competition and prevent SMEs from being excluded by legal complexity. The statement also calls for a proportionate approach, requesting practical guidance, standard contractual clauses and well-resourced enforcement authorities to support smaller companies. It notes that in certain sectors, supplementary legislation may be needed for full clarity.

The coalition concludes that strong enforcement is paramount, asserting that without it, the Act's rights will remain theoretical. They warn that any delay or softening of key provisions risks reinforcing the very market barriers the regulation was designed to eliminate. The signatories urge the Commission to ensure robust enforcement to secure a competitive and innovative Single Market for all companies.
