Kia opts for low noise Kumho tyres on its new EV6 electric vehicle (EV)

The EV6, Kia’s first battery electric vehicle (BEV), is to be supplied with low noise Kumho tyres. The all-season CRUGEN HP71 and high-performance ECSTA PS71 in 235/55R19 size will be fitted to the EV6, which is Kia’s first car based on the company’s dedicated new E-GMP (Electric-Global Modular Platform) electric car technology.

Both tyre patterns exhibit significantly less resonance noise than standard products, thanks to Kumho’s patented sound-absorbing technology, dubbed K-Silent. The K-Silent system works by optimising the shape and properties of polyurethane foam materials placed within a tyre. The result of which is a marked reduction in the air vibration generated by the tyre during contact with the road surface.

Kumho developed the K-Silent system back in 2014 and holds patents for it in its native Korea as well as other countries around the world. Both the HP71 and PS71 feature other properties that make them ideal for tyres intended for use on electric vehicles, such as low rolling resistance, strong anti-wear performance and excellent levels of grip.

UK customer deliveries of the new Kia EV6 will commence from October 2021 and it offers up to 295 miles (475km) of range. This speedy mover is capable of reaching 62mph (100kph) in 3.5 just seconds. On a more practical level, it boasts ultra-fast charging and can be charged up to 80 percent in just 18 minutes.

The fitting of low noise tyres makes the vehicle not only more relaxing to drive, but also helps to keep noise pollution down for those around, especially in built-up areas.

Kim Insoo,  Kumho Tire senior vice president of OE sales, said: “The low resonance noise tyres we have developed with our proprietary K-Silent system for the Kia EV6 demonstrate our ability to meet the needs for sustainable mobility.

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