In a tire having a belt ply that is formed from ply strips arranged at intervals in the tire circumferential direction, in order to prevent deterioration in durability when high modulus organic fibers are used in a band cord, said tire is provided with a belt layer comprising a belt ply, and a band layer comprising a band ply positioned to the outside of the belt layer in the radial direction. The belt ply is formed by a plurality of ply strips, which are narrow and have a prescribed length, arranged side-by-side with intervals therebetween in the tire circumferential direction. The band ply is formed by a ply tape, which is narrow and long, wound spirally in the tire circumferential direction. The band cord comprises a composite cord in which first strands, which comprise high modulus organic fibers, and second strands, which comprise low modulus organic fibers and are narrower than the first strands, are twisted together.

A belt cover layer is formed by spirally winding belt cover materials including a first cover material and a second cover material. When one side in a tire width direction with respect to a tire equatorial plane is defined as a first side and another side is defined as a second side, the first cover material is disposed from a position between a shoulder region on the second side and the tire equatorial plane to a shoulder region on the first side. The second cover material is disposed from a position between the shoulder region (Ash) on the first side and the tire equatorial plane to the shoulder region on the second side. The first cover material and the second cover material have an overlapping portion at a position where positions in the tire width direction become positions identical to one another.

Pneumatic vehicle tire with specified belt bandage

A pneumatic vehicle tire for passenger cars comprises a carcass, a tread, and a belt which has belt plies and which is covered radially outwardly by a belt bandage having strengthening elements oriented approximately in the circumferential direction, the belt bandage comprising at least one belt bandage ply each consisting of a central section and two lateral sections each arranged next to the central section without overlapping the central section, the strengthening elements of the central section being x1 construction and the strengthening elements of each lateral section being identical cords of x2 or higher construction, the density of the strengthening elements in the central section being less than the density of the strengthening elements in the lateral sections, and the axial distance of each lateral section inner end from the closest end of the widest belt ply being 5-30 mm.
