Did you know that your tires have a direct impact on your car's fuel efficiency? It's true, as the tires design and air pressure can cause you to spend more or less at the pump. Fortunately, Hankook built the Enfren ECO (H433) to help drivers of hybrid and electric cars save even more at the pumps. A special rubber compound reduces rolling resistance to strengthen fuel efficiency, and the Enfren ECO (H433)'s tread design boosts traction and handling performance in wet and dry conditions while vibration control technology creates a comfortable ride for drivers and passengers.
