A rubber composition for a tire tread which comprises (A) a rubber component selected from the group consisting of natural rubber and synthetic diene-based rubbers, (B) 5 to 50 parts by weight per 100 parts by weight of the rubber component of (b1) aluminum hydroxide particles which are treated with a surface treating agent on the surface and have an average diameter of secondary particles D2 of 10 &mgr;m or smaller or (b2) aluminum hydroxide particles which have an average diameter of secondary particles D2 of 0.8 &mgr;m or smaller and a ratio (D2/D1) of the average diameter of secondary particles D2 to an average diameter of primary particles D1 of 1.7 or smaller and (C) 5 to 80 parts by weight per 100 parts by weight of the rubber component of at least one filler selected from carbon black and silica. The rubber composition is used for a tire tread and provides a tire which exhibits improved abrasion resistance while the excellent performance on wet roads and the low fuel consumption exhibited by a tire using a conventional rubber composition containing aluminum hydroxide are maintained.
