摘要： According to a production method of a rubber composition for tire of the present invention comprising a rubber component (A) comprising at least one selected from the group consisting of a natural rubber and a synthetic diene rubber, a filler, a coupling agent (D) represented by the following chemical formula (1), and a vulcanizing agent (E) comprising a vulcanizer and a vulcanization accelerator, the method comprising: (step X1) a step X1 of kneading all amount of A, a part of the filler and a part of D, (step X2) a step X2 of kneading the kneaded product of step X1, the remaining amount of the filler and D, and (step F) a step F of kneading the kneaded product of step X2 and E, it is possible to produce a rubber composition for tire in which fuel efficiency and abrasion resistance are improved in a good balance. Chemical formula (1): (C p H 2p+1 O) 3 -Si-(CH 2 ) q -S-CO-C k H 2k+1 In the chemical formula (1), p represents an integer of 1 to 3, q represents an integer of 1 to 5, and k represents an integer of 5 to 12.
