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.
