A pneumatic radial tire of the present technology has a belt reinforcing layer and a tread rubber. The belt reinforcing layer comprises a composite fiber cord having one aromatic polyamide fiber cord and one aliphatic polyamide fiber cord twisted therein. A total fineness of the composite fiber cords is from 1800 to 3200 dtex and an elongation under a load of 2.0 cN/dtex is from 3.0 to 4.0%. A rubber composition constituting the tread rubber is 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 m2/g with 100 parts by weight of a diene rubber. A loss compliance of the rubber composition at 60° C. is not greater than 45 Pa−1.
