To provide a pneumatic radial tire capable of effectively preventing generation of air intrusion between a center part and a side part of a circumferential direction cord belt layer and generation of overlapping of both parts, etc., when manufacturing the tire.
A belt 3 is composed of a radial carcass 2, one or more inclining cord belt layers 4, and one or more circumferential direction cord belt layers 5. The circumferential direction cord belt layer 5 is formed of the center part 5a positioned at a center area in the width direction and a pair of the side parts 5b positioned adjacent to both sides of the center part 5a. The center part 5a and the side parts 5b are arranged radially inside/outside to be separated by one or more inclining cord belt layers 4 between them.
