ABSTRACT:
The tread reinforcement of a high-speed radial tire comprises at least one folded ply of twisted metal cords. The direction of the fold of the ply, the direction of the inclination of the cords with respect to the circumferential direction of the tire, and the direction of the twist of the cords are such, relative to one another, that the cords are relatively untwisted at the fold. Thus, in the case where the ply is folded radially outward, the folded ply and the cords composing it are both type S or both type Z, while in the case where the ply is folded radially inward, the folded ply and the cords composing it are of opposite S/Z type.
