K-Silent is a tire noise-reducing technology developed by KUMHO TIRE. It is designed to reduce interior noise on all road surfaces. K-Silent tires are equipped with an inner tire absorber, a polyurethane foam, attached to the inner surface of the tread area with an adhesive. Regardless of the temperature, the structure of the foam stays intact. K-Silent helps reduce interior vehicle noise, depending on the type of vehicle, its speed and the road surface. Driving performance is not affected and there is no negative influence on mileage and load/speed capability.
