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.   

Bridgestone is supplying Custom-engineered Alenza A/S tyre with ENLITEN Technology to select models of the 2021 Nissan Rogue as an OE supplier.

The Nissan Rogue is the first vehicle in the U.S. and Canada to feature tyre with Bridgestone’s ENLITEN Technology.

Thanks to new 3D GripControl sipes, the tyre also offers enhanced wet braking and handling. Hankook says the model brakes 15 percent faster and handles seven percent better in wet conditions than its predecessor.   

The tyremaker also focused on comfort, using knurling technology to reduce road noise. The Dynapro HPX is available in sizes ranging from 16 to 19 inches.

“With the Dynapro HPX, we are presenting the newest member of our tyre family, which is specifically designed for the different requirements of SUVs and all-wheel-drive vehicles,” says Sanghoon Lee, President and COO of Hankook Tire Europe. “We are proud to be able to offer our customers a tyre with very high mileage without any compromise on comfort and safety.”

Yokohama has started delivering tyres to the new Impreza as original equipment (OE) in North America. 
The new Impreza cars will have AVID S34 tyres (size P225/40R18 88V).

The AVID S34 belongs to the AVID series of all-season tyres for passenger cars sold in the North American market, and it features the “M+S” (mud & snow) marking on its sidewall.

The AVID S34 tyres’ wide tread ensures a larger contact area, providing stable driving performance not only on dry roads but also on snow. In addition, the tread pattern design features a large number of grooves that effectively grip the surface of snowy roads and improve the vehicle’s safety and performance in snowy conditions. The tyres’ structure also has been enhanced to reduce vehicle wobble during lane changes.
