ABSTRACT:
A metal cord for reinforcing rubber articles and a pneumatic tire including metal cords to reinforce tire components such as carcass, breaker and band are disclosed, wherein a metal cord according to one aspect of the present invention comprises filaments having a tensile strength of from 4000 to 5500 N/sq.mm and a diameter of from 0.10 to 0.35 mm and the filaments are twisted together, the filaments before twisted are two-dimensionally waved so that the elongation after fracture of the cord becomes in a range of from 2 to 6%. According to another aspect of the present invention, the metal cord is a single filament having a tensile strength of from 4000 to 5500 N/sq.mm and a diameter D of from 0.10 to 0.35 mm, and the filament is two-dimensionally waved so that the elongation after fracture becomes in a range of from 2 to 6%.
