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)

Bridgestone’s Potenza Sport EVO has earned two independent test accolades, strengthening the tyre maker’s standing in the ultra-high-performance segment. The double success spans a victory in What Car?’s summer tyre test and a Recommended award from evo.

In What Car?’s evaluation of 11 summer tyres, the Potenza Sport EVO ranked first. Fitted to a Volvo XC60, it drew praise for predictable handling and secure performance in wet and dry conditions, along with communicative steering suited to a premium performance tyre.

The What Car? results also underscored tyre choice’s safety implications. In wet braking, the Bridgestone stopped 7.3 metres shorter than the Goodride competitor. The publication concluded that the Potenza Sport EVO justified its higher price, highlighting the value of investing in quality tyres.

The evo test delivered further recognition. The Potenza Sport EVO finished second overall but secured the Recommended award and was arguably the standout performer across individual disciplines, taking five first-place finishes. It earned top subjective ratings for polished, effortless behaviour, excelled in wet grip, traction and stability and set the fastest handling-course time, becoming the only tyre to break 51 seconds.

Drew Chapman, Consumer Sales Director, Bridgestone UK, said, "To achieve such outstanding results in two highly respected independent tyre tests is a fantastic endorsement of the Potenza Sport EVO and the engineering that has gone into its development. Winning the What Car? test against 10 other competitors, while also securing evo's Recommended Award and five individual test victories, demonstrates the tyre's exceptional breadth of capability. These results reflect exactly what we set out to achieve with the Potenza Sport EVO; delivering outstanding performance, control and confidence in a wide range of driving conditions. It's hugely rewarding to see that recognised by independent experts."

Pirelli is all set for the winter season with its winter tyre range that is renewed over the past two years. The newly launched Scorpion Winter 3 joins the P Zero Winter 2 for high-performance cars and the Cinturato Winter 3 for saloons and crossovers. The range is available with Pirelli Elect technology for electric vehicles. Independent tests by European organisations have placed Pirelli winter tyres at the front in safety-related areas, while the Cinturato All Season SF3 has recorded four victories and six additional podium finishes.

Winter tyres or suitable equipment are required from 15 November to 15 April. Most winter driving occurs on dry and wet roads. Below 7°C, winter compounds offer more grip than summer compounds, and the tread pattern helps counter aquaplaning and generate traction on snow. Sidewall markings indicate capability: M+S identifies a product for challenging surfaces, while 3PMSF certifies testing in harsh conditions. An appropriate winter driving style includes increased safety distance, avoiding sudden acceleration and reducing brake use in favour of engine braking.

The Cinturato Winter 3 took first place in the 2026 ADAC winter tyre test in size 225/50 R17 against 16 models, earning a highly recommended rating with the best wet score and the highest assessment for driving safety. It won the AvD test in size 225/45 R17 against 15 tyres with a very good rating. It also finished first in the Auto Bild comparison in size 205/55 R16 on a Volkswagen Golf against 14 tyres with an exemplary rating. Podium finishes followed in tests by Auto Express, Auto Bild Allrad and Tyre Reviews, giving six podium finishes in seven tests, including three victories.

The Scorpion Winter 3 debuted with a victory in the alVolante comparison in size 235/60 R18 on an Alfa Romeo Stelvio, ranking first among six winter tyres. Its wet performance, shortest braking distance, fastest lap time and progressive reactions set it apart. It was judged consistent and predictable on snow and balanced on dry roads.

In the annual Auto Bild super comparative test, the P Zero Winter 2 finished on the podium with an exemplary rating, thanks to precise driving behaviour in wet and dry conditions and braking performance on both surfaces. The Cinturato Winter 3, Scorpion Winter 3 and P Zero Winter 2 are available with Pirelli Elect technology on dedicated fitments for Europe's electric vehicle fleet. Elect addresses low rolling resistance for range, acoustic comfort, longer tyre life, grip for immediate torque and a reinforced structure for battery weight.

All-season tyres suit drivers mainly in urban areas covering up to 20,000 km per year without frequent heavy snowfall. Higher mileage, regular mountain travel or high-performance cars generally call for winter tyres. The Cinturato All Season SF3 carries the 3PMSF marking and has four victories in comparisons by Auto Zeitung, Reifentester, Auto Express and Que Choisir, plus six additional podium finishes. The new Scorpion All Season SF3 extends the approach to SUVs.
