Hankook Optimo H426B (*). FEATURES AND BENEFITS: All season traction; Fuel-efficient drive; Run flat tire model; Enhanced controllability; . OVERVIEW: The Hankook Optimo H426B (*) is a touring, all season tire made for passenger vehicles. This model is the original equipment tire of select BMW vehicles.The symmetric tread design and the all season compound enhance the tires performance throughout the year. In this manner, the optimized tread elements closely follow the road surface at all times, while the special silica compound keeps the rubber flexible in changing temperatures. This combination upgrades the tires dry, wet, and winter-weather traction. On the other hand, the optimized grooves effectively eliminate water and slush from the footprint on wet roads.The model offers great controllability and durability. The symmetric tread pattern and the special silica compound work together to maintain constant contact with the driving surface. It improves the tires steering responsiveness and driving stability. In other words, the tires steering response time is faster and more precise to the drivers commands, while the structure is secured against the driving pressure. At the same time, the wide shoulder blocks boost cornering and maneuvering. These elements enable the driver to have full control over the vehicle and guarantee a safe driving experience.This tire is manufactured with run flat technology. The reinforced internal structure keeps the ideal tire shape under the driving pressure even after air pressure loss. This enables the tire to be driven for 50 miles up to the speed of 50 mph even after air pressure loss. This limited, temporary performance guarantees the tires secured performance at all times. Run flat tires should not be mounted on the same vehicle as regular tires.The Hankook Optimo H426B (*) is fuel-efficient. The ideal tread design and the special silica compound reduce the tires rolling resistance. It presents the pressure that determines how much energy the vehicle needs to keep the tires in motion. This low rolling resistance reduces the vehicles fuel consumption and CO2 emissions, which ensures a fuel-efficient and environmentally friendly driving experience. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
