Tailored steel belt package

The steel belt package tailored for the double body structure is durable. The pocket strips integrated into the edges of both steel belts are a unique design feature. This solution ensures that the steel belts are durable in heavy use and that they can be securely attached to the structure. The new, more flexible steel cord both improves the structural durability and allows the tire to retain its state-of-the-art characteristics for longer than before. At the same time, this solution reduces rolling resistance, in turn enhancing fuel economy.
