The Hankook Optimo K425 Kinergy Eco is an eco-friendly touring summer tyre manufactured by applying a new mixing technology that uses nano-scale silica particles. The tyre reduces CO2 emissions and offers a better handling experience. It can be fitted to most passenger cars. The K425 Kinergy Eco ensures an improved wet braking and wet handling performance. This is made possible by the lateral shoulder groove and three channelled groove patterns in the tyre. The tread pattern also includes a sawtooth type technology and optimised block stiffness that provides a better dry handling performance. The asymmetric tread design allows for a smooth and quiet ride. The K425 Kinergy Eco furnishes a comfortable ride while improving fuel efficiency. This is achieved by Hankook's vibration control technology.
