The present invention provides a tire rubber composition prepared by mixing at least one rubber component selected from natural rubbers and synthetic diene rubbers (A), a filler including an inorganic filler (B), a silane coupling agent (C) and a thiosemicarbazone derivative (D), and provides a production method for a tire rubber composition, wherein the tire rubber composition is kneaded in plural stages, and in the first stage of kneading, the rubber component (A), all or part of the inorganic filler (B), all or part of the silane coupling agent (C), and the thiosemicarbazone derivative (D) are kneaded, therefore providing a tire rubber composition having improved reactivity between the coupling agent and the rubber component and excellent in low-heat-generation property and a production method for the composition.
