    Abstract: A steel cord (114) comprises strength elements (100, 132) and having a length, a longitudinal central axis (112) and a cord pitch. At least one of the elements (100) has a projection on a plane YZ perpendicular to the longitudinal central axis (112). This projection takes the form of a curve with a radius of curvature which alternates between a maximum and a minimum. The curve further has a center of curvature. The radius of curvature and the center of curvature lie inside the curve so that a convex curve is obtained. The cord (114) is further characterized by one or both of following features: (i) the distance between two minimum radii of curvature of said curve measured along the longitudinal central axis (112) is different from half the cord pitch; or (ii) if all of said elements (100) provide a convex curve, at least one of said convex curves substantially differs from another convex curve.

    Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of reducing the cord fatigue and enhancing the durability by reducing the initial elongation, and suppressing the dispersion thereof.
    SOLUTION: In the pneumatic tire, a tire component consisting of plies covering cord arrays with metallic cords arranged parallel to each other with a tread rubber is used. The metallic cords are formed by stranding a plurality of metal filaments. In the metallic cords taken out of the pneumatic tire, the initial elongation E which is the difference (E1-E2) between the elongation E1 under the load of 49N and the elongation E2 under the load of 2.5N is set in a range of 0.05-0.20%, and the initial elongation E is the mean value for the metallic cords taken out of the positions at which the arranged cords in the entire circumference of the tire are equally divided into n-sections (n=20), including the metallic cord group in which the standard deviation σ obtained by the formula σ=√(Σ(Ei-Em)
    2 /n), where Ei is the i-th initial elongation from the reference position (i=1), and Em is the mean value of the initial elongation of n pieces of metallic cords.
