The present invention relates to a rubber composition comprising a rubber component (A) comprising at least one member selected from natural rubber and synthetic diene rubber, a filler containing an inorganic filler (B), a silane coupling agent (C), and a guanidine, And at least one vulcanization accelerator (D) selected from thiazoles, and an organic acid compound (E), wherein the rubber composition is kneaded in a plurality of stages, (A), all or a part of the inorganic filler (B), all or a part of the silane coupling agent (C), the vulcanization accelerator (D), and the organic acid compound (E) Wherein the molecular number X of the organic acid compound (E) in the rubber composition in the step (1) is in the relationship of the following formula (1) to the molecular number Y of the vulcanization accelerator (D) Preferably it suppressed activity reduction in the coupling to the function of, and provides a production method capable of obtaining a rubber composition for the rubber composition to be more cool. &Quot; (1) " |
