Hankook is supplying the Porsche Taycan with its Ventus S1 evo 3 ev tyre, which has been developed for the needs of electric vehicles.

“We are proud to equip the first fully electric sports car from Porsche with our tyres,” said Hankook Tyre Europe president, Sanghoon Lee.

“Providing the original equipment for sporty premium vehicles is already a tradition at Hankook. Our engineers have shown that with our products, we are well prepared for the new demands in the field of electric sports cars and are therefore well positioned for the future.”

The tread pattern of the Ventus S1 evo 3 was adapted in the EV version for Porsche in such a way it reduces in particular tyre noises which may be perceived as annoying in the vehicle interior due to the absence of engine noise by around three decibels.

To meet the heavy demands of high performance of electric sports cars, the tyre has a reinforced bead with so-called bead-packing technology, as well as lateral stiffness for precise handling even at speed.

“With the tyre development for the Porsche Taycan, our development team has moved into completely new dimensions and we are proud of the result,” added European Research and Development Centre head, Klaus Krause.

“For the original equipment engineers, such a development project represents a special challenge – because solving the conflict of objectives for optimising the various performance criteria in an e-vehicle like this high-performance sports car requires the highest level of expertise and the latest technologies.”

To meet the specific demands of an electric vehicle such as the Porsche Taycan, Hankook says its developers have developed a vulcanisation process for the tyre compound that ensures the right balance of temperature, time expenditure and pressure.

As a result, Ventus S1 evo 3 ev achieves 30% greater durability compared to a standard tread compound.

Abrasion resistance has been improved by 5% compared to the conventional model and rolling resistance has been improved by 13% overall.
