Tire and tire production method

A tire comprising a pair of bead portions,

• a carcass straddling between the pair of bead portions in a toroidal shape, and
• a belt consisting of one or more belt layers disposed on the outer side in the tire radial direction of a crown portion of the carcass, wherein
• the belt layer is composed of tape-like members consisting of a plurality of belt cords arranged parallel to each other and coated with rubber, arranged in the tire circumferential direction,
• the tape-like member has a tape width of 1 to 10 mm, and
• at the end portions of the belt layer, two of the tape-like members adjacent to each other in the tire circumferential direction are arranged such that the belt cords thereof do not overlap each other in the tire radial direction.

A tire production method for a tire comprising a pair of bead portions, a carcass straddling between the pair of bead portions in a toroidal shape, and a belt consisting of one or more belt layers disposed on the outer side in the tire radial direction of a crown portion of the carcass, wherein

• the method includes a raw tire forming process:
• using a toroidal-shaped rigid core with a tire forming surface that forms a luminal surface of the tire on its outer surface, and sequentially attaching unvulcanized tire components including carcass plies and belt plies on the tire forming surface of the rigid core to form a raw tire,
• the raw tire forming process includes a belt ply forming process:
• forming the belt ply via the carcass ply on the tire forming surface of the rigid core,
• the belt ply forming process includes an attaching process:
• attaching tape-like members with a tape width of 1 to 10 mm, consisting of a plurality of belt cords arranged parallel to each other and coated with rubber, sequentially in the tire circumferential direction at a predetermined angle to the tire circumferential direction, to form a belt ply composed of the tape-like members arranged in the tire circumferential direction, and
• in the attaching process, on the tire equatorial plane, two of the tape-like members adjacent to each other in the tire circumferential direction are attached so that they are butted against each other at tire circumferential ends thereof.
