Abstract: The steel cord for reinforcement of an off-road tire has a superior resistance to penetration and durability with respect to sharp objects. It has a 3.times.3, a 3.times.4, a 4.times.3 or a 4.times.4 structure, an identical cord diameter at all points along the steel cord in a longitudinal direction, a cord lay length equal to from 3.5 to 7.5 times the cord diameter and an elongation at break of at least 4%. The steel cord is made up of element wires, each having a wire diameter of from 0.3 to 0.5 mm and a tensile strength of from 2000 to 3300 MPa.

Abstract: A cord has a core including a plurality of wires, and an outer layer including a plurality of wires and surrounding the core. The wires of the core and of the outer layer are twisted together. All the wires of the core have a diameter larger than the wires of the outer layer, thereby guaranteeing a gap between adjacent wires of the outer layer.
