Abstract:
A cable useful for reinforcement of tires, comprising a plurality of steel wires, each of said wires consisting essentially of pearlitic, work-hardened carbon steel and having a diameter ranging between about 0.05 mm and 0.8 mm, the carbon content of the steel ranging between about 0.4% and 1% (% by weight of steel), each of said wires having an individually applied adherent coating favoring adhesion between the cable and rubber parts of a tire, the cable having an operational elongation rate (Af), before and after the molding of the tire, that is greater than 4%, wherein the operational elongation rate (Af) is the sum of the elastic elongation rate (Ae) and the plastic elongation rate (Ap).
