    Abstract: A steel cord for use as reinforcing materials for rubber products, especially automobile tires.
    For improving rubber penetrativity and break-resistance, three to six material wires are intertwisted into a steel cord having a cross section of elliptical shape of
    with adjoining material wires substantially contacting with each other at the area of both ends of the ellipse and separating from each other at the other area. Where necessary, a high elongation of more than 5% is imparted by intertwisting material wires at

    Abstract: A cord with an elongated cross-section and adapted for the reinforcement of plies in a pneumatic tire, comprises a layer of steel filaments that are wound around an untwisted monofilament core, the monofilament core having a tensile strength of at least 1800 N/mm², an elongation at rupture of at least 2 per cent and a breadth-to-thickness ratio of at least 2. This structure combines the properties of flat wires with those of steel cords having substantially round cross-sections.

    Abstract: To provide a pneumatic tire wherein the lightweight properties of a tire is secured while improving the plunger energy and BES resistance thereof, which is particularly suitable for tires for a large passenger car or extra load tires. A pneumatic tire comprising a carcass 1 as a skeleton, and at least two belt layers 2a, 2b each formed by rubberizing a plurality of steel cords arranged obliquely with respect to the tire circumferential direction on the outside in the tire radial direction of the crown portion of the carcass is provided. The steel cord is composed of two or more core wires and five to seven sheath wires twisted together around the core wires; the interval between adjacent steel cords in the belt layer is more than 1.0 mm and not more than 1.50 mm; and the gauge of the belt layer is not less than 1.20 mm and not more than 1.60 mm.
