Abstract: A zero degree tire reinforcing steel cord is formed by twisting together four to seven individual wires having a wire diameter of 0.20 to 0.45 mm, wherein the steel cord has a substantially spiral or a substantially planar wavy deformation, has an elongation of 1.2% to 2.0% under a tensile load of 50 N and becomes substantially linear with its wavy deformation disappearing under a tensile load of 50 to 250 N. The steel cord stretches to a moderate extent so as to track expansion of the tire in the radial direction during the vulcanization process and thereafter restrains expansion of the tire in the radial direction during continued high speed rotation of the tire.
