Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rubber composition which is excellent in processability and is excellent in low fuel consumption performance and abrasion resistance when formed into a tire.SOLUTION: The rubber composition for a tire contains a diene rubber, silica, and a cationic surfactant. The silica has a CTAB adsorption specific surface area of 115-300 m/g. The cationic surfactant is a quaternary ammonium salt having a carboxylic acid ester bond. The content of the silica is 50-200 pts.mass based on 100 pts.mass of the diene rubber. The content of the cationic surfactant is 0.05-10 pts.mass based on 100 pts.mass of the diene rubber.SELECTED DRAWING: Figure 1 【課題】加工性、ならびに、タイヤにしたときの低燃費性能および耐摩耗性に優れたゴム組成物を提供する。【解決手段】ジエン系ゴムと、シリカと、カチオン界面活性剤とを含有し、上記シリカのＣＴＡＢ吸着比表面積が１１５〜３００ｍ２／ｇであり、上記カチオン界面活性剤がカルボン酸エステル結合を有する４級アンモニウム塩であり、上記シリカの含有量が上記ジエン系ゴム１００質量部に対して５０〜２００質量部であり、上記カチオン界面活性剤の含有量が上記ジエン系ゴム１００質量部に対して０．０５〜１０質量部である、タイヤ用ゴム組成物。【選択図】図１
