    • Provided is a pneumatic radial tire capable of improving the belt durability effectively while retaining the excellent abrasion resistance of a tread surface. On the outer side of the crown area of a toroidal carcass (5) anchored by a pair of bead cores (4) and on the inner side of a tread rubber (7), two belt-reinforcing layers (8a and 8b) made of circumferentially extending reinforcing elements, and a belt (10) formed of two belt layers (9a and 9b) made of individual belt cords extending backward of each other with respect to the tire equatorial plane (E) are individually arranged sequentially from the inner side of the radial direction.The width (w1) of the belt cord entangled areas of the two belt layers (9a and 9b) is set to 65 % to 90 % of the tire width (W), and the maximum width (w0) of the belt-reinforcing layers (8a and 8b) is set to 60 % to 85 % of the tire width (W). The belt radius ratio of the difference (R0-R1) between the radius (R0) on the tire equatorial plane and the radius (R1) at the belt side edge position of the belt (10) in the position of the tire charged with the regular internal pressure, to the belt half width (w/2) is 0.06 or less.
