    摘要: The present invention relates to a method for producing a rubber composition obtained by compounding a rubber component (A) containing at least one kind selected from natural rubber and synthetic diene rubber, a filler containing an inorganic filler (B), a silane coupling agent (C), and thiourea, the method comprising kneading the rubber composition in plural stages, the rubber component (A), the whole or a part of the inorganic filler (B), the whole or a part of the silane coupling agent (C), and the thiourea being kneaded in the first stage of kneading, and thus provides a method for producing a rubber composition excellent in low-heat-generation property through enhancement of the reactivity between the coupling agent and the rubber component.
