HOCHLEISTUNGSREIFEN MIT EINER LAUFFLÄCHE, DIE EINE TEMPERATURSTABILE ANISOTROPISCHE UNTERSCHICHT HAT |
摘要 |
A high performance tire includes a carcass provided with at least one carcass ply, a belt including two or more layers of reinforcing cords parallel to each other in a layer and crossed with respect to those of an adjacent layer, applied circumferentially on the carcass, a radially-external layer of circumferentially-oriented reinforcing cords applied on the belt, and a tread band comprising an underlayer and an external layer. The underlayer may have a hardness which is substantially constant over a temperature range between 23° C. and 100° C. The underlayer may also have an elastic modulus which is substantially constant over a temperature range between 70° C. and 100° C. Additionally, the underlayer may be made from an elastomer compound comprising reinforcing fibers and hardening resins. Further, the underlayer may have a hardness and an elastic modulus which remain substantially constant between 70° C. and 100° C. A method for making the tire is also disclosed. |
