    Abstract: A metal cord includes at least one preformed elementary metal wire. The metal cord has an elongation at break, measured on the bare cord, higher than or equal to 3%, preferably 4% to 6%; an elongation at break, measured on the rubberized and vulcanized cord, which differs in an amount not higher than or equal to 15%, preferably 2% to 10% with respect to the elongation at break measured on the bare cord; a part load elongation, measured on the bare cord, higher than or equal to 0.4%, preferably 0.5% to 1.5%; a part load elongation, measured on the rubberized and vulcanized cord, which differs in an amount not higher than or equal to 15%, preferably 0.5% to 10%, with respect to the part load elongation measured on the bare cord.

    Abstract: A tire reinforcing steel cord (1, 10) is provided which has a 1nulln structure formed by twisting together four to seven individual wires having a wire diameter of 0.20 to 0.45 mm, the steel cord being wound a plurality of times in the vicinity of opposite side edges of a belt section of a tire, wherein the steel cord has a substantially spiral or a substantially planar wavy deformation, has an elongation of 1.2% to 2.0% when applying a tensile load of 50 N in a tensile test according to JIS B 7721, and becomes substantially linear with its wavy deformation disappearing under a tensile load in the range of 50 to 250 N. When the steel cord is embedded in a tire as a zero degree belt cord, it stretches to a moderate extent so as to track the expansion of the tire in the radial direction during the vulcanization process in the molding of the tire, and since the steel cord has low stretch after the tire has been molded, it is possible to restrain expansion of the tire in the radial direction during continued high speed rotation of the tire.
