[PROBLEMS] To improve low exothermic property of a rubber composition by a simple method. A thiol compound having at least one functional group selected from the group consisting of an amino group, a nitro group, a hydroxyl group, a carboxyl group, a nitrogen-containing heterocyclic group and an alkoxysilyl group (for example, 4-mercaptophenol, 3-mercaptopropyl) trimethoxysilane, etc.), premixing using a kneader without compounding silica, and blending and mixing silica into the resulting premix A process for producing a rubber composition. [Selection figure] None |
