To obtain the subject composition excellent in fuel economy and excellent in balance between wet performance and abrasion resistance as well.

This rubber composition for tire treads comprises 100 pts.wt. of a stock rubber including, (A) as stock rubber component, a both terminal- modified styrene-butadiene polymer where one terminal of a polymer containing 10-50 wt.% of styrene and 10-70 wt.% of 1,2-vinyl-bonded butadiene component is coupled and the other terminal amine-modified, and as filler components, (B) 10-80 pts.wt. of carbon black and (C) 10-80 pts.wt. of silica so that the amounts of the components B and C total 35-90 pts.wt.
