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.   

New Renault Clio To Run On Continental EcoContact 7 Tyres

New Renault Clio To Run On Continental EcoContact 7 Tyres

The new Renault Clio will feature Continental's EcoContact 7 tyre as original equipment for its global launch. Approved in numerous countries, the compact car will be fitted with this model in two specific sizes: 195/60 R16 and 205/45 R18. Both variants have earned the highest possible ratings on the EU tyre label for fuel efficiency and low rolling noise, underscoring their performance credentials.

This high performance stems from several integrated technological advancements. A newly formulated rubber compound works in concert with Continental’s Smart Energy Casing, which employs innovative materials in the tyre’s internal structure to minimise friction and rolling resistance. Further efficiency gains are achieved through an aerodynamically refined sidewall. This design incorporates a dimpled texture, inspired by the surface of a golf ball, to smooth airflow and reduce the energy required to keep the tyre in motion.

Alongside its energy-saving properties, the tyre is engineered for refined acoustics. A specifically designed Silent Pattern tread layout alters the arrangement and angles of the tread blocks to target and dampen the frequency of noise typically produced during low-speed urban driving. This focus results in a reduction of rolling noise, enhancing comfort for those inside the vehicle and contributing to a quieter environment for pedestrians and city residents alike.

Giti Tire Adds First Winter Tyre to Its EV Ready Range Ahead of 2025/26 Season

Giti Tire has expanded its AdvanZtech EV Ready line with the launch of the GitiWinterW2, its first winter tyre designed for electric, hybrid and conventional vehicles. The company said the new model is now available for ordering for the 2025/26 winter season.

The GitiWinterW2 will be offered in 17 sizes ranging from 15- to 20-inch rims. All products carry the AdvanZtech EV Ready sidewall mark, indicating suitability for internal combustion vehicles as well as mild hybrid, plug-in hybrid and battery-electric models.

The range is intended to cover a wide span of the European car parc, from small cars such as the Fiat 500e to larger vehicles including the Tesla Model 3, Volkswagen Tiguan and Volvo XC60 PHEV. Giti said each tyre has been tuned for EV-specific demands such as torque management, while maintaining low rolling resistance and strong performance on snow and wet roads.

The manufacturer highlighted three core attributes for the GitiWinterW2: a quiet and comfortable ride, strong safety characteristics and precise control in winter conditions.

The winter tyre joins the GitiSportS2 and GitiSynergyH2 summer patterns in the EV Ready strategy first announced in August 2024. All three products were developed using Giti’s AdvanZtech R&D framework at its European Research & Development Centre in Hannover, Germany.

Fabio Pecci-Boriani, Deputy General Manager for Product Planning PCR and LTR at Giti Tire’s European R&D Centre, said the company aimed to give both drivers and dealers greater clarity as electrification reshapes the market. “The Giti brand was among the first in the mid-market to introduce an EV ready concept, ensuring maximum flexibility and product clarity for dealers and peace of mind for drivers.”

He added that winter conditions pose specific challenges for electrified cars. “As is proven winter can have an impact on the performance of part-electric and electric vehicles with lower temperatures reducing battery range and immediate torque levels being tricky on slippery roads, the Giti AdvanZtech EV ready GitiWinterW2 goes a long way to addressing these issues.”

Giti said its EV Ready strategy remains a central pillar of its European product plans as the shift towards hybrid and battery-electric vehicles accelerates.
