Title:
温度変動に対し安定した異方性の下層を有するトレッドバンドを具備する高性能タイヤ
Document Type and Number:
Japanese Patent JP4649083
Kind Code:
B2
Abstract:
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.
