Pneumatic tire with metal cord and method of manufacturing metal cord

A pneumatic tire includes metal cords each made of metal filaments twisted together, the metal cords having an initial elongation in a range of from 0.05 to 0.20 % and a standard deviation of the initial elongation in a range of not more than 0.02. A method of manufacturing the metal cord comprises shaping metal filaments in a two-dimensional zigzag waveform, and twisting the shaped metal filaments together, wherein the number of the filaments is in a range of from 8 to 12, the metal filaments have the same diameter (d) of
