  • High-performance pneumatic tire having bead fillers of anisotropic elasticity
    Patent number: 4711285
    Abstract: Disclosed is a high-performance tire in which a bead filler formed of a rubber composition fills up a space between each turn-up portion of the carcass and a major portion of the carcass and extends to some extent along the carcass toward the tread. The rubber composition is anisotropic such that the elastic modulus in the direction circumferential of the tire is distinctly higher than in the direction radial of the tire. Such anisotropy can be produced by incorporating short fiber of a suitable thermoplastic polymer such as nylon into the rubber composition. This tire provides both improved controllability and a good ride.
