Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rubber composition for a tire, which improves dispersibility of silica not to raise viscosity of unvulcanized rubber, and which improves heat buildup to obtain excellent processability.SOLUTION: A rubber composition for a tire is obtained by combining silica with a cetyltrimethylammonium bromide (CTAB) adsorption specific surface area of 180 to 250 (m/g), to a rubber component selected from natural rubber and/or diene-based synthetic rubber, with mono-alkanol amide of silica in formula (I) [In the formula (I), Ris an alkyl group or an alkenyl group of carbon number 1 to 13, the alkyl group or the alkenyl group may be in a straight chain shape, a branch chain shape or a circularity shape, and Ris a hydroxyalkyl group or a hydroxyalkyl group that has an oxyalkylene unit].
