Kumho Tyre has been selected to supply innovative low noise tyres for Kia’s new EV6 electric car, with  235/55R 19 Kumho Crugen HP71 and Ecsta PS71 to be OE fitment on the new battery electric model.

With no noise from an internal combustion engine, electric car users are exposed to sounds from other elements in the car, particularly tyre noise, which is not usually detected in a conventional vehicle, but becomes more prominent in an electric car,

To combat this situation, Kia has specified Kumho’s latest technology, low noise and low rolling resistance tyres, which deliver a low resonance noise, thanks to the tyre maker’s K-Silent sound absorption technology.

The two Kumho tyre models chosen, both offer features required for tyres dedicated to electric vehicles (EVs), including a low rolling resistance, good anti-wear performance, and excellent traction.

The sound absorption materials are made of polyurethane foam, which is inside the tyres, to help reduce the resonance noise caused by the air vibration within the tyre, generated when it makes contact with the road.

To maximize resonance noise reduction, the K-Silent technology optimises the shape and properties of the sound absorption materials.

At the heart of this solution is a configuration that takes into account a range of elements including the design, area, and width of the sound absorption materials.

Kumho developed its K-Silent system in 2014 and has gained patents for the shape and properties of the sound absorption materials in Korea and around the world.

“We are now able to meet the needs for sustainable mobility by offering tyres with a low resonance noise that was developed with our proprietary K-Silent system for the EV6, the first BEV released by Kia,” said Kim Insoo, senior vice president of OE Sales at Kumho Tire.

“In line with the vision embodied in our slogan ‘Your Smart Mobility Partner,’ we will grow with our customers by developing advanced technologies and products in response to the fast transition to future-oriented vehicles,” said Km Insoo.

The EV6 is Kia’s first battery electric vehicle (BEV) and is based on Hyundai Motor Group’s latest Electric Global Modular Platform (E-GMP), and is a next-generation electric vehicle platform.

It offers a maximum range of up to 475 kilometers from a full charge, and is capable of reaching 100km/h in 3.5 seconds, as well as boasting ultra-fast charging, which allows it to charge to 80 per cent in just 18 minutes.

The EV6 Featuring a modern and stylish interior and exterior design and is an industry-leading smart mobility vehicle.

Kumho has also been chosen as the OE tyre supplier for Hyundai’s new Staria people mover.

Kumho’s Portran KC53 in both 17 and 18 inch sizes have been selected for the new Staria as a result of the tyre’s strong anti-wear performance and durability, as well as accommodating the specific needs of the Staria while also delivering excellent driving stability.
