Abstract
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) of (CpH2p+1O)3—Si—(CH2)q—S—CO—CkH2k+1, and a vulcanizing agent (E) comprising a vulcanizer and a vulcanization accelerator, the method comprising: a step X1 of kneading all amount of A, a part of the filler and a part of D, a step X2 of kneading the kneaded product of step X1, the remaining amount of the filler and D, and 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.
