Abstract
A steel cord () comprises a plurality of steel filaments () arranged in parallel to the longitudinal axis of the steel cord () without twisting. The steel cord () further comprises a wrapping filament () twisted around the steel cord (). Each of said steel filaments () is a flat wire having flat surfaces. The steel filament () near the center of the steel cord () has a bigger width than the steel filaments () further away from the center of the steel cord () such that the cross-section of said steel cord () approximates an oval shape with the bending stiffness around the shorter axis of the oval shape being greater than the bending stiffness around the longer axis. In a tire, the steel cord being used as a reinforcement, the longer axis being arranged perpendicular to the radial direction of the tire.
