The invention provides a tread rubber composition, tread rubber and a preparation method. The tread rubber composition is prepared from the following components in parts by weight: 100.0 parts of rubber, 10.0 to 20.0 parts of carbon black, 30.0 to 45.0 parts of white carbon black, 1.5 to 6.0 parts of a silane coupling agent, 0.5 to 2.0 parts of a white carbon black dispersing agent, 0.1 to 2.0 parts of protective wax, 1.5 to 5.0 parts of an anti-aging agent, 0.5 to 3.5 parts of stearic acid, 2.0 to 5.0 parts of indirect method zinc oxide, 0.8 to 3 parts of an accelerant and 0.8 to 2.0 parts of sulfur, the rubber is prepared from 30.0 to 100.0 parts of natural rubber and 0 to 70.0 parts of synthetic rubber. A proper amount of carbon black and white carbon black are added into the tread rubber composition, so that the heat generation amount of tread rubber can be effectively reduced, the electrical conductivity of the tread rubber is improved by adopting the silane coupling agent, the static electricity accumulation of a tire in the running process is reduced, and the safety is improved.
