    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.

    Abstract: A steel cord for reinforcing rubber articles in which sheath wires are not deviated and which has an excellent rubber penetration property and a tire which has an excellent durability using the steel cord is provided.
    A steel cord for reinforcing rubber articles composed of a core 10 composed of two untwisted steel wires 1 and six sheath wires 2 which are twisted around the core 10 is disclosed. The average of gap distances between the adjacent sheath wires 2 is 24 µm or larger, and the occupancy of the sheath wires 6 disposed around the core 10 with respect to a sheath wire disposition area is 80% or larger. A pneumatic tire in which the steel cord is applied on both a carcass and (a) belt layer(s) or applied on either the carcass or the belt layer(s) is also disclosed.
