Kumho Tire is providing a low noise tire for the Kia EV6.
A tire whose resonance noise has been significantly reduced.
The EV6 is Kia’s first battery electric vehicle (BEV) that is based on the Electric Global Modular Platform (E-GMP), a next-generation electric vehicle platform for Hyundai Motor Group automobiles.
It offers a maximum of up to 475 kilometres from a full charge, is capable of reaching 100km/h in 3.5 seconds, and boasts ultra-fast charging, which allows it to charge to 80% only in 18 minutes.
The EV6 is fitted with Kumho’s all-season tire Crugen HP71 and Ecsta PS71 (235/55R 19).
Both of which have a low resonance noise thanks to the tire maker’s sound-absorbing solution dubbed K-Silent.
The two models offer features required for tires dedicated to electric vehicles (EVs) such as:
- low rolling resistance
- good anti-wear performance
- driving power
The sound absorption materials made of polyurethane foam inside the tires help reduce the resonance noise caused by the air vibration within them that is generated when the tire makes contact with the road.
To maximize resonance noise reduction, the K-Silent system optimizes the shape and properties of 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 sound absorption materials used for tires.
Kumho developed the K-Silent system in 2014 and has obtained patents for the shape and properties of sound absorption materials in Korea and other countries around the world.
“We are now able to meet the needs for sustainable mobility by offering tires 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.”
