The invention discloses an all-steel radial tire base rubber formula, and relates to the technical field of rubber processing. Theall-steel radial tire base rubber formula is prepared from the following components in parts by mass: 70 to 100 parts of natural rubber; 0 to 30 parts of high cis-butadiene rubber; 0 to 20 parts of white carbon black; 20 to 45 parts of carbon black; 2 to 6 parts of zincoxide; 1-3 parts of stearic acid, 0-3.2 parts of a silane coupling agent, 0-1 part of a low-rolling-resistance auxiliary agent, 0-3 parts of a super tackifying resin, 0.5-2 parts of a protective wax,1-3 parts of an anti-aging agent RD, 1-3 parts of an anti-aging agent 4020, 1-3 parts of an accelerant NS, 1-4 parts of insoluble sulfur HDOT20 and 0-0.4 part of an anti-scorching agent. According tothe tire base rubber prepared by the invention, a tire has relatively low tire rolling resistance; meanwhile, the wear-resisting property is good, and the overall wear-resisting property of the tirecan be improved when the tire is used in cooperation with a conventional tire tread; the base rubber prepared by the invention is used in tires, can reduce oil consumption in automobile driving, and also meets the requirements of customers on high wear resistance of the tires.
