摘要： A tire component used in a pneumatic radial tire is a rubber-coated layer comprised of a given number of reinforcing elements separately arranged in parallel with each other, in which the reinforcing elements corresponding to at least 30% of all reinforcing elements included in the rubber-coated layer are divided into plural groups, and a distance between mutually adjoining and opposite reinforcing elements not grouped with each other is wider than a distance between mutually adjoining reinforcing elements separately arranged at equal spaces in the group. Thus, the occurrence of cracking at cut ends of the reinforcing elements is prevented to improve the tire durability.
