PROBLEM TO BE SOLVED: To provide a pneumatic radial tire for improving maneuvering stability, comfortableness, and durability in a well-balanced state while reducing weight. SOLUTION: In this pneumatic radial tire, belt ply for forming a belt 2 wound on a crown part of a carcass 1 of a radial structure is formed by putting covering rubber 10 on a wire layer 9 formed by arranging a longitudinal wave wire 7 having an oval cross section, and patterned in a waveform bending in the minor axis direction, and a transverse wave wire 8 patterned in a waveform bending in the major axis direction. |
