ABSTRACT:
The present invention is directed to bead wires which has a Cu/Sn deposit having an Sn content of 9 to 13% by weight and a Cu content of 91 to 87% by weight, in an amount of 0.65 to 0.85 g per kilogram of the wire. The present invention is also directed to rubber-coated bead wires for tires comprising the plated bead wire as mentioned above, a rubber layer formed on the bead wire from a composition comprising 100 parts of a rubber polymer, 80 to 140 parts of a carbon, 4 to 10 parts of sulfur, 0.4 to 0.9 part of a vulcanization accelerator, 10 to 7 parts of zinc oxide, and 1 to 4 parts of stearic acid, and to tires prepared by using the above-mentioned bead wires. The bead wires of the present invention have excellent adhesion between the plated bead wire and the rubber layer, so that the tires obtained using such bead wires avoid wild wires.
