PNEUMATIC RADIAL TIRE WHICH ACTED CODE MEMBER FOR TIRE REINFORCEMENT, ITS MANUFACTURING PROCESS, AND THE CODE MEMBER FOR TIRE REINFORCEMENT

摘要

PROBLEM TO BE SOLVED: To provide a tire code member for reinforcing radial tire and its manufacturing process in which durability is increased by suppressing lowering strength in a band piece in a joining part, and also to provide a pneumatic radial tire using the material. SOLUTION: The invention relates to a tire code member material 1 and its manufacturing process, wherein a wave shaped convex-concave surface is formed in a band piece 2 and opposite side edge surfaces in a joining part Q of the band piece 2, and a convex part and a concave part in a wave convex-concave surface of the band piece 2 are jointed to each other, and also relates to a pneumatic radial tire 11 using a code member for tire reinforcement 1.
