ELECTRIC CARS ARE UPSTREAM, SO THEIR TYRES IN FRONT TO SAY TOO MUCH .

By Ertugrull Bahan, Senior Tyre Expert

Electric cars will surely be more on board than in recent decades. They are becoming more popular, more commercial, the market volume of the middle and upper classes will increase more than today. The inconsistencies associated with high sales costs and a short battery charge distance are generally overlooked. Brand popularity depends mainly on entry price and customer service.

New brands for the production of electric cars will appear on the market. The manufacture of high-tech electric cars becomes easier and more convenient because fewer transmission components are used than conventional cars. However, the spectrum and capacity of AI determine the comfort of mobility. Solid software support for brand awareness will therefore be more dominant than the physical parts of the vehicle.

Low weight and cheaper batteries

Humanity must still be patient with flying cars! Next generation cars will be purely electric, so the total load will always be borne by wheels and tyres.There is still a space where the weight of electric cars can be reduced with lighter and additive manufacturing features. However, these are not yet completely possible for industry.The battery of an electric car is today the heaviest part of the vehicle and weighs around 500 kg. The weight of the batterywill determine the all aspects of the electric car.Due to the total body weight, todayelectric car tyres are not light load tyres and their size depends on the total weight of the car. New lighter battery technologies will shape future electric cars and their tyres. Technical reasons point to tall tire sizes with a rim size of 19 inches and more with a smaller cross-sectional width and stiffer sidewall for electric car tyres.

Electric car manufacturers must plan long distances on a single charge anyway. Any successful design of vehicle parts therefore aims for low energy consumption. Higher battery weight, more braking energy and larger brake pedals hinder this goal. The regenerative ability feature braking and driving downhill are therefore on the table and the preference for a working electric car.

Quieter, lighter, easier to grip tyres

It is reasonable for automakers to expect energy efficient electric car tyres.In this regard, the tyres should have less rolling resistance, but should also contain a rubber composition that manages the current torque of the electric motors. The high torque and weight of the heavy vehicle challenge optimal performance. Better grip, lower rolling resistance and better tyre wear performance require opposite directions of the magic triangle. The use of silica-silane has already been carried out with conventional tyres. This means that the structure and material of electric car tyres have a unique design and must be different from conventional car tyres.

Electric cars offer a quiet driving experience, so any noise source other than the low-noise electric drive train is annoying to the driver. A larger outside diameter with a stiffer sidewall and a high inflation and cavity are disadvantageous for a better noise level. If a shallow skid depth is used for better pattern noise, wear resistance will decrease. However, a high instantaneous torque mainly requires better tyre wear. Because other performance parameters are balanced during the development phase, including wet and dry traction, life is not easy for tire manufacturers as they need of many newsizes after the spread of electric vehicles in all segments. All bring us the concept of "active tyres" also referred to as "intelligent tyres," which means that all necessary services are available in good time if necessary. However, this is a completely new and challenging area, consisting of the possibilities of non-air-filled tyres and the use of nano-additives in traditional blends. Otherwise, electric car tyres will also be a mixture of today's technologies. They will be the best possible compromise for the most important parameters.

New technologies, government incentives to prevail

Other technological developments for powerful tyres for electric cars will prevail.Developing foam layer technologies for tire noise reduction is one alternative for quit tyres.  Previous foam filled tyres as alternative to run-flat technologies will be on scene for the purpose of lowering the tire and road noise for a better riding performance of an electric car and its tyres.

Around 2 million electric car sales is expected to reach to ten times more in ten years in overall world and electric car volume reaches 530 total million market volume in 20 years. Many countries will ban diesel engine and limit gasoline fuel car sales. Governments will play major roles shaping the global market with incentives. 30% less noise and 20% less rolling tyres will be average technology and requirements of next tire labeling requirements. Future tyres will be anyhow more technological. Caching up all has to be started by better power of will and imagination.   

Pirelli Develops Bespoke P Zero R Tyre For New Official FIA F1 Safety Car

Pirelli Develops Bespoke P Zero R Tyre For New Official FIA F1 Safety Car

Pirelli has introduced the P Zero R, an ultra-high-performance tyre created specifically for the Mercedes-AMG GT 63 PRO 4MATIC+, unveiled as the first Official FIA F1 Safety Car fitted with fully variable all-wheel drive. The tyre blends qualifying-level dry performance with precise steering response while maintaining safe wet handling and was engineered to deliver consistent performance during Formula 1 Safety Car deployments, where precision, reliability and control are essential.

The dual-compound tread and tread pattern details, developed through virtualisation, allow high performance in both dry and wet conditions. Co-developed with Mercedes-AMG engineers in Affalterbach and refined using virtual simulation models central to Pirelli's development process, the compounds, land-to-groove ratio and tread channel widths work in synergy with the vehicle's suspension geometry and camber. This optimises the contact patch, maximising grip and steering precision while enhancing high-speed stability without sacrificing wet performance.

The project forms part of Pirelli's role as Formula 1's sole tyre supplier since 2011, a position recently confirmed by the FIA and Formula 1 and extended through to 2028. The relationship stretches back to the inaugural race in 1950, and Pirelli has accompanied the championship's technical evolution, reaching 500 Grands Prix in 2025. Experience gained on track, including in extreme conditions, gives Pirelli a laboratory for innovation whose findings also feed into road tyre development.

Designed to put the power of its 4.0-litre twin-turbo V8 engine onto the road, the 21-inch P Zero R supports an engine producing 450 kW (612 hp) and 850 Nm of maximum torque. The car offers high performance and drivability thanks to the fully variable AMG Performance 4MATIC+ all-wheel-drive system, which demands tyres capable of coping with rapid load transfers while letting the car exploit its dynamic potential.

Extensive testing at the Nürburgring and Nardò involved AMG brand ambassador and Official FIA F1 Safety Car Driver Bernd Mayländer and other experienced Safety Car drivers, who praised the tyre's consistency and grip across a wide range of conditions. The first P Zero R developed specifically for a Mercedes-AMG, it confirms a longstanding collaboration built on co-development from the earliest stages of vehicle development, resulting in more than 150 fitments. The tyre carries the MO1 sidewall marking, identifying it as specifically developed for this model.

The previous Official FIA F1 Safety Car from the Affalterbach performance and sports car brand, the Mercedes-AMG GT Black Series, which served from 2022 to 2026, also ran on Pirelli P Zero tyres. The latest milestone in the partnership came at the Nürburgring Nordschleife, where the Mercedes-AMG CLA 45 4MATIC+ fitted with Pirelli P Zero Trofeo RS tyres set a record of 7:32.070 minutes, claiming the title of fastest vehicle in its segment on the legendary German circuit.
