Wattrun VS31 – Kumho’s Exclusive Tyre for Electric Vehicles
Kumho introduced Wattrun VS31, an exclusive tyre for electric vehicles in urban areas. It is an ultra-light tyre that weighs 25 per cent less compared to general tyres. With an A/A grade EU labelling, the Wattrun VS31 is said to provide good fuel efficiency, excellent grip and handling on wet road as well as quiet and smooth driving.
With an asymmetric block design that take into consideration the high torque electric vehicle characteristic, the dry and braking performance of Wattrun VS31 is greatly enhanced. Durability, low rolling resistance and noise are achieved through its solid rib tyre centre block design. Tyre road noise is reduced through optimised block sequence and sipe technology, while its three wide grooves pattern provides good water dispersion for strong wet performance.
Other features include higher cord density and optimised belt angle that provide improved uniform contact pressure and wear, and profiled lower tread that enhances tread block stiffness and provides lower rolling resistance. The new optimal bead profile is said to optimise rim contact pressure for handling improvement.
To enhance Wattrun VS31’s emphasis on the electric vehicle’s characteristics and eco-friendly image, its sidewalls are made with a battery image.
The company’s research and development efforts were paid off with Wattrun VS31 winning Germany’s Reddot Design Award 2018 in the category of ‘concept design’.
Since 1955, the annual German Reddot Design Award along with the country’s IF Design Award and the US’s IDEA Design Award are the three awards recognised as the biggest industrial design standards in the world. Through the three design categories of product, communication and concept, originality, usability and practically are the areas judged. The winning products are displayed at the Reddot Design Museums in Germany and Singapore. Kumho Tyre has achieved the triumph of winning the Reddot Award for seven consecutive years, from 2012 to 2018.
