A rubber composition for a tire tread, and a tire having a tread part comprising the composition are provided to improve abrasion resistance and rolling resistance. A rubber composition for a tire tread comprises a master batch which comprises 1-20 parts by weight of a tertiary amine; 20-100 parts by weight of silica; and 1-10 parts by weight of a silane coupling agent based on 100 parts by weight of an ionized rubber substituted with vinyl benzyl chloride or vinyl benzyl bromide. Preferably the tertiary amine is selected from N,N-dimethylstearylamine, an alkyldimethylamine, dicocoalkylamine, distearylamine, cocoalkyldimethylamine, N,N-dimethylallylamine, dimethylamine, and N,N-dimethyldodecylamine. |
