ABSTRACT:
A rubber-covered belt ply forms a belt layer. At least a majority of metal wires in the ply exist as metal wire bundles in which a plurality of metal wires of circular cross-sections and substantially equal wire diameters are aligned in parallel without being twisted together, the metal wire bundles being aligned planarly and in parallel with intervals between the metal wire bundles in a transverse direction. At least one layer, which is a cap layer in which organic fibers are covered with rubber and/or a reinforcing layer which is formed of rubber or whose main component is rubber, is disposed between the belt layer and a tread.
