The invention discloses a cord fabric rubber compound formula for truck radial tire. The formula comprises 70-100 parts of smoke sheet rubber, 0-10 parts of gas carbon black, 15-25 parts of mixed gas carbon black, 15-17 parts of general purpose furnace black, 10-15 parts of high abrasion furnace black, 15-25 parts of semi reinforcing furnace black, 5-7.5 parts of zinc oxide, 2.0-2.5 parts of stearic acid, 3.0-3.5 parts of pine tar, 2-2.5 parts of an antioxidant RD, 2.5-2.7 parts of sulfur, and 1.1-1.7 parts of an accelerator CZ. The prepared cord fabric rubber gains significantly improved fatigue resistance, viscosity, themogenesis, heat resistance, and ageing resistance.
