In a method for producing a tire rubber composition comprising a raw material rubber, carbon black, a carbon black coupling agent, a vulcanization accelerator, an anti-aging agent, a vulcanization agent, and a vulcanization accelerator, the first is to mix only the raw material rubber, carbon black, and carbon black coupling agent. step; A second step of adding and mixing a vulcanization accelerator and an anti-aging agent to the rubber composition of the first step; And a third step of adding and mixing a vulcanization accelerator and a vulcanizing agent to the rubber composition of the second step. |
