An object of the present invention is to provide a method for producing a rubber composition, which can further enhance the activity of a coupling function of a silane coupling agent to obtain a rubber composition that preferably has low heat generation. A rubber component (A) containing at least one selected from natural rubber and synthetic diene rubber, a filler containing an inorganic filler (B), a silane coupling agent (C), and the following general formula ( A method for producing a rubber composition comprising at least one hydrazide compound (D) represented by I), wherein the rubber composition is kneaded in a plurality of stages, and in the first stage of kneading, the rubber component (A) A method for producing a rubber composition, comprising kneading all or part of the inorganic filler (B), all or part of the silane coupling agent (C), and the hydrazide compound (D). It is. [Selection figure] None |
