Abstract:
The present invention relates to a method for producing a rubber composition containing a rubber component (A) of at least one selected from natural rubbers and synthetic dienic rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization promoter (D), wherein the rubber composition is kneaded in multiple stages, and in the first stage of kneading, the rubber component (A), all or a part of the inorganic filler (B), and all or a part of the silane coupling agent (C) are kneaded, and then on the way of the first stage, the vulcanization promoter (D) is added and further kneaded. The production method enables production of a rubber composition having a low-heat-generation property while successfully preventing the coupling function activity of the silane coupling agent from lowering.
