South Korea’s tyre maker Hankook Tire has introduced its second-generation electric vehicle tyre, the Kinergy AS EV, which features strengthened handling and noise-reducing capabilities that are optimised for today’s cutting-edge electric vehicles.
Compared to internal combustion engine vehicles, electric vehicles have lower engine noise, higher initial acceleration and bodies that are 10 to 20% heavier. In order for electric vehicles to achieve optimal performance, they need tyres designed to complement these unique characteristics.
The Kinergy AS EV is engineered to meet the increasingly demanding specifications of electric vehicles. It provides a hyper-low noise environment suitable for electric vehicles and a comfortable riding and supreme driving performance on par with ultra-high performance tires.
Electric vehicles are free from engine noise, which makes road and tyre noise more noticeable, and in turn noise reduction is of utmost importance for comfort driving. The hyper-low noise environment is created with application of advanced noise reduction technologies.
Kinergy AS EV shows maximum quietness by applying techniques that reduce the noise produced from tyre and the road. Technology to reduce a certain frequency that incurs when driving through optimum pitch arrangement was also applied.
Electric vehicles are usually heavier than normal vehicles, so each tyre needs to take on more load stress. In order to cover the extra weight, Kinergy AS EV is produced with aramid hybrid reinforcement belt, and employs extra-load reinforcement structure. This allows little or no increase in diameter even in high-speed driving and minimises tread block distortion when changing direction, thereby maintaining optimum grip force to provide handling performance and significantly improve handling stability.
Another key improvement is the application of Aqua Pine compound, resin extracted from conifers and consist of environment-friendly vegetable oil. With the new compound, performance improves on wet roads, securing agile handling and braking in all road conditions. This improves driving stability while reducing tire slip and minimising tread abrasion to deliver the high power of the electric motor and powerful initial acceleration with no loss.
Kinergy AS EV will be available in South Korea this year, and global launch is also under review for next year.
