Abstract: A radial tire having excellent cornering stability and high-speed durability is disclosed. The tire has a belt composed of a first structural body, which consists of a single rubberized cord layer containing cords of twisted metal wires and is folded at both lengthwise end portions, and a second structural body consisting of at least one rubberized cord layer containing unextensible cords, wherein the cord of twisted metal wires used in the first structural body has a specifically limited twisting construction and a specifically limited elongation.

Abstract: A belt structure of a pneumatic tire with plies (13, 15) consisting of alternating S and Z twist cords and the edges of at least one ply folded.

Abstract: A radial ply tire has a belt structure with a pair of edge strips of square woven fabric. A portion of each edge strip is disposed between a pair of belt plies that are adjacent to one another, and the edge strips may be folded around the respective axial edges of the radially innermost belt ply.

Abstract: In a pneumatic tire of the type which consists of a pair of right and left beads, a pair of right and left side walls continuing the beads, respectively, and a tread interposed between the side walls, and in which a carcass cord layer is spread between the beads, and at least two layers consisting of a belt reinforcing layer whose reinforcing cords have a cord angle of from 15.degree. to 30.degree. with respect to the circumferential direction of the tire and a belt reinforcing layer whose reinforcing cords have a cord angle of from 150.degree. to 165.degree.

Abstract: An asymmetrical belt for a radial carcass pneumatic tire comprises two steel plies of which one ply is a single cut ply and the other ply is a folded ply comprising a main body portion and a radially outwardly folded portion. The two plies are arranged such that the single cut ply is situated radially outwardly of the folded ply with one end portion lying within the bite formed by the fold of the folded ply. The belt configuration further comprises a textile ply which extends across the median portion and the non enclosed end portion of the single cut ply. The textile ply is preferably composed of parallel cords making an angle of not more than 10.degree. with the mid-circumferential plane of the tire.
