(EN) The present invention provides a method for producing a rubber composition comprising a rubber component (A) consisting of at least one selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C), and thiourea. The method for producing a rubber composition is characterized in that the rubber composition is kneaded in multiple steps, and in the first kneading step, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C), and the thiourea are kneaded. The method improves the reactivity of the coupling agent and the rubber component to produce a rubber composition that is excellent in terms of low heat emission.
