<P>PROBLEM TO BE SOLVED: To provide a rubber composition for a tire tread, which allows a tire product to have low fuel consumption without damaging the breaking elongation and wear resistance thereof and to provide a pneumatic tire made by using the rubber composition. Ž<P>SOLUTION: The rubber composition for the tire tread is obtained by blending ≥20 parts mass carbon black having 110-180 m<SP>2</SP>/g CTAB adsorption specific surface area, ≥10 parts mass silica having 95-175 m<SP>2</SP>/g CTAB adsorption specific surface area, 1-20 parts mass oil-extended white clay and 0.2-5.0 parts mass specific polyether polyol in 100 parts mass diene rubber so that the total amount of the carbon black, the silica and the oil-extended white clay is 35-150 parts mass.
