Abstract
A pneumatic tire comprises a carcass toroidally extending between a pair of bead portions and a belt arranged outside the carcass in a radial direction of the tire and composed of at least one belt layer, in which the belt layer is made from a plurality of steel cords, each cord being formed by twisting 2 to 4 filament bundles each consisting of two steel filaments paralleled with each other so as to have a structure that major axes of the filament bundles constituting the cord are set toward substantially the same direction. In the belt layer, the major axes of the filament bundles in the cords constituting the belt layer are arranged substantially in a row in a widthwise direction of the belt.
