    Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic radial tire capable of not only enhancing cut separation-resistance by external damage and enhancing tire durability at buckling deformation generated when it is used at blowout and is used at less than a specified internal pressure.
    SOLUTION: In the pneumatic radial tire, a steel cord having a core molded to a wave shape and a sheath is used as a belt reinforcement material. An angle θ formed by an amplitude direction Wb and a belt width direction Wa of wave shape-molding of the core is within a range of 0-35°.

    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord for reinforcing a rubber product, used as a reinforcing material of the rubber product such as a tire for a vehicle and an industrial belt, and having an extremely flat shape and fatigue resistance.
    SOLUTION: The steel cord for reinforcing the rubber product, having a 3+N structure obtained by twisting N (N is 5-13) wires forming sheath side around a core consisting of three wires is regulated so that the core wires 11 may be parallel to each other, and arranged in one nearly linear direction at the cross section of the cord to form the cord cross section into the extremely flat shape, and the core wires 11 may satisfy the requirements in P of from 0.22Pc to 0.43Pc and in d1 of from 1.02d to 1.05d [wherein, P is the pitch (mm) of kink; Pc is a twisting pitch (mm) of the sheath wire; d1 is an apparent outer diameter (mm); and d is a diameter (mm) of the core wire] to facilitate the stretch of the core wire 11 and to enable a tensile load to be dispersed to the core wires 11 and the wires 12 at the sheath side.

    Abstract: PROBLEM TO BE SOLVED: To provide a reinforcing material for rubber articles, which can ensure extensibility on productive processing and can enhance stiffness in the circumferential direction, especially when applied to tire, and to provide a tire using the same.
    SOLUTION: This reinforcing material for the rubber articles, comprising a core cord material 1 and six or more wound cord materials 2 wound on the core cord material 1, is characterized in that the core cord material 1 has a breaking elongation of ≥3%; the maximum value G
    max of a distance between the adjacent wound cord materials 2 satisfies the following expression: 0 max ≤3×d in the rubber article, when the average diameter of the circumcircles of the wound cord materials 2 is d; and the total amount G
    total of distances between the adjacent wound cord materials 2 satisfies the following expression: G
    total ≥6×d before processed or in a state that the reinforcing materials are taken out from the rubber article and then subjected to the removal of the rubber.
