Bead wires having 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 0.85g per kilogram of the wire, rubber coated bead wires for tyres 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, 90 to 140 parts of a carbon, 4 to 10 parts of sulphur, 0.4 to 0.9 part of a vulcanisation accelerator, 10 to 17 parts of zinc oxide and 1 to 4 parts of stearic acid and tyres prepared by using the above mentioned bead wire. The bead wires of the present invention are excellent in adhesion between the plated bead wire and the rubber layer, so, in the tyres obtained using such bead wires, it is difficult to cause the wild wires.
