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)

 The U.S. Tire Manufacturers Association (USTMA) is convening its annual Tire Manufacturing Ambassadors programme this week, sending industry professionals to Capitol Hill to press lawmakers on policies supporting domestic manufacturing, road safety and sector innovation.

The two-day event, running from 24–25 June, brings together representatives from USTMA’s 11 member companies — including engineers, business managers and marketers — to meet with members of Congress and their staff. The discussions are expected to focus on key legislative priorities such as expanding tyre retreading in the U.S., advancing consumer safety initiatives, and passing a congressional resolution in support of National Tire Safety Week.

“The U.S. tyre manufacturing industry is a vibrant engine of innovation, enabling safe and sustainable mobility for consumers and businesses. Our industry is a cornerstone of the nation’s economy, supporting more than 800,000 jobs and keeping up with evolving consumer expectations on reliability, safety and environmental impact,” said Anne Forristall Luke, USTMA president and CEO.

The ambassadors, who live in the same communities where the industry operates, are set to highlight how national legislation impacts local jobs and infrastructure. USTMA members operate 55 manufacturing facilities across 16 states and contribute to a $170.6 billion annual economic footprint, the association said.

The event follows a letter sent by USTMA to Congressional leaders in February outlining the sector’s legislative agenda. The group is advocating for increased investment in tyre innovation, transparency measures for consumers, and job creation through infrastructure and sustainability-focused policies.

“Our Ambassadors represent the manufacturing workers who power the industry every day, and we are honoured by their advocacy for the tyre manufacturing industry and the communities it supports,” Luke added.

The initiative reflects USTMA’s broader push to align policymakers with the industry’s goals of maintaining global competitiveness while securing long-term growth for U.S. manufacturing.
