The invention discloses a guide tire tread rubber composition for an all-steel radial tire and a guide tire tread rubber preparation method, and relates to the technical field of tire rubber material preparation. The guide tire tread rubber composition for the all-steel radial tire is prepared from the following components in parts by weight: 55 to 65 parts of natural rubber, 0 to 25 parts of butadiene rubber, 20 to 45 parts of butadiene styrene rubber, 45 to 55 parts of carbon black, 0.05 to 0.25 part of peptizer, 1.5 to 2.5 parts of stearic acid, 3 to 5 parts of indirect method zinc oxide, 1 to 2 parts of anti-aging agent RD, 1.5 to 2.5 parts of anti-aging agent 4020, 1 to 2 parts of protective wax, 1 to 1.5 parts of sulfur powder, 1 to 1.5 parts of accelerant NS and 0.1 to 0.4 part of scorch retarder CTP. 1-3 parts of a functional aid, 0.4-1 part of a natural rubber modifier and 0.2-0.6 part of a styrene butadiene rubber modifier. The invention discloses a guide tire tread rubber composition and a guide tire tread rubber preparation method. According to a guide wheel prepared by the guide tire tread rubber composition, the driving safety, comfort, wear resistance, eccentric wear resistance and oil saving property of a vehicle are remarkably improved.
