摘要： 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 earl y breakage of the wi res 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.

摘要： Provided by the present invention is a technique which can, in a pneumatic radial tire using corrugated steel cords in the circumferential bent, improve the durability of the corrugated steel cords in order to prevent fatigue rupture thereof caused by an increase in energy input.
The present invention is a pneumatic radial tire which has a carcass 1 as the skeleton extending in a toroidal shape between a pair of bead portions on either side of the tire, as well as a belt layer 2 and a tread layer 5 successively arranged thereonto at the outer part in the tire radial direction. The belt layer 2 comprises at least one layer of circumferential belt 3 which comprises a plurality of corrugated or zigzag-shaped steel cords extending along the tire circumferential direction, and when the steel cords are removed from the circumferential belt 3, the bending radius of curvature (R) of the steel cords is within the range from not less than 18 mm to not more than 125 mm.
