PROBLEM TO BE SOLVED: To provide a pneumatic radial tire in which road noise in a high frequency range is reduced without increasing the mass of the tire. SOLUTION: In the pneumatic radial tire 1, both ends of a carcass layer 3 are mounted on a pair of right and left bead cores 2 and 2, and two belt layers 5 and 5 are disposed on the outer circumferential side of the carcass layer 3 in a tread part 4. At least two bent parts A and B are formed on both ends of the belt layers 5 and 5 so that the bent parts A and B are continuous to each other in the circumferential direction of the tire.
