Provided is a pneumatic radial tire which achieves both a reduction in weight and high-speed durability. The pneumatic radial tire of the present invention has a belt reinforcing layer (7) and a tread rubber (9); the belt reinforcing layer (7) comprising a composite fiber cord (8) having one aromatic polyamide fiber cord and one aliphatic polyamide fiber cord twisted therein; a total fineness of the composite fiber cords being from 1800 to 3200 dtex and an elongation under a load of 2.0 cN/dtex being from 3.0 to 4.0%; and a rubber composition constituting the tread rubber (9) being formed by compounding from 10 to 110 parts by weight of a silica having a nitrogen adsorption specific surface area of not less than 100 m 2 /g with 100 parts by weight of a diene rubber, and a loss compliance of the rubber composition at 60°C is not greater than 45 Pa -1 .
