Zusammenfassung:PROBLEM TO BE SOLVED: To prevent or depress growth of cracks generated on a groove bottom and to provide a pneumatic radial tire having superior operation stability perfor mance. SOLUTION: In a pneumatic tire having a pair of right and left bead cores placed at bead part, a radial carcass, and belt contg. a two-layered main belt layer, the two-layered main belt layer consists of a low-angle belt layer in which a cold is placed in the 15 to 30-degree direction to the peripheral direction of a tire, and a high-angle belt layer in which a cord is placed in the 25 to 50 degree-direction to the peripheral direction of the tire. The cord of the high- angle belt layer and the cord of the low-angle belt layer are placed in reverse directions by sandwiching the equator of the. Its cross angle is 5 to 35 degrees. The cord of the high-angle belt layer consorts of a metallic cord.
