    Abstract: A steel cord is configured so that, when the steel cord is used as a tensile cord for an elastic crawler, a center-core dislocation and the early breakage of the wires of a core are prevented. A steel cord comprises: a core which comprises a single core strand, and a sheath which is formed by twisting together six sheath strands arranged around the core. The core strand has a layer-twisted structure comprising: a center-core portion which is formed by twisting three core wires together; and an external layer portion which is formed by twisting together eight to nine core wires arranged around the center-core portion. The sheath strands each have either a bundle twisted structure which is formed by twisting twelve to nineteen sheath wires or a multi-layer twisted structure which is formed by twisting twelve to nineteen sheath wires in layers. The diameter (dc) of the core wires is greater than the diameter (ds) of the sheath wi res. The average gap (Gc) between the core wi res of the external layer portion is 0.015 mm or greater, and the average gap (Gs) between the sheath strands is 0.1 mm or greater.

    Abstract: In the pneumatic tire of this invention, at least the outermost one of a plurality of rubber layers between the carcass and tread has been reinforced with a plurality of steel cords. Each of these steel cords is a single-strand steel cord with an elongation at break of not less than 4% and at least one of its component wires does not form a common circumcircle with the remaining wires. The curve circumscribing the cross-sections of the constituent wires of each steel cord is not a true circle. Furthermore, a high resistance to nail penetration is assured by arranging the steel cords in such a manner that, for a large majority of steel cords, the direction of maximum offset span of the circumscribing curve is substantially coincidental with the width direction of the outermost layer of rubber.
