Zusammenfassung:PROBLEM TO BE SOLVED: To provide a manufacturing method of a rubber composition for tire having low fuel consumption, abrasion resistance, wet grip performance and conductivity which are improved in a good balance.SOLUTION: There is provided a manufacturing method of a rubber composition for tire containing a rubber component containing at least one kind selected from a group consisting of natural rubber and diene-based synthetic rubber (A), silica (B), predetermined carbon blacks (C1) and (C2), predetermined coupling agents (D1) and (D2) and a vulcanization-based agent containing a vulcanizer and a vulcanization accelerator (E) and including a Process X1 for mixing A, a part or all amount of B, C1, D1 and optionally a part of E, a Process X2 for mixing the mixture of the Process X1, residual amount of B, C2, D2 and optionally a part of E and a Process F for mixing the mixture of the Process X2 and residual amount of E. Chemical formula (1) (CHO)-Si-(CH)-S-CO-CH.SELECTED DRAWING: None 【課題】低燃費性、耐摩耗性、ウェットグリップ性能および導電性がバランス良く改善されたタイヤ用ゴム組成物の製造方法を提供すること。【解決手段】天然ゴムおよびジエン系合成ゴムからなる群から選ばれる少なくとも1種を含むゴム成分(A)、シリカ(B)、所定のカーボンブラック(C1)および(C2)、所定のカップリング剤(D1)および(D2)、ならびに加硫剤および加硫促進剤を含む加硫系薬剤(E)を含有するタイヤ用ゴム組成物の製造方法であって、A、Bの一部または全量、C1、D1、および任意でEの一部を混練りする工程X1、工程X1の混練物、Bの残量、C2、D2、および任意でEの一部を混練りする工程X2、ならびに工程X2の混練物、およびEの残量を混練りする工程Fを含むタイヤ用ゴム組成物の製造方法。化学式(1) (CpH2p+1O)3−Si−(CH2)q−S−CO−CkH2k+1【選択図】なし
