PROBLEM TO BE SOLVED: To provide a rubber composition capable of improving the balance of road surface-griping properties, high mileage and abrasion resistance in a tire by sufficiently drawing out properties of an inorganic filler such as silica while keeping the processability at a practical level. SOLUTION: The rubber composition comprises a dienic rubber, the inorganic filler and a silane coupling agent represented by general formula (1): (C<SB>n</SB>H<SB>2n+1</SB>O)<SB>3</SB>Si-C<SB>m</SB>H<SB>2m</SB>-S-CO-C<SB>k</SB>H<SB>2k+1</SB>(wherein, n is an integer of 1-3; m is an integer of 1-5; and k is an integer of 5-9). The rubber composition for a tire tread is obtained by using the rubber composition as a master batch, adding other dienic rubbers, zinc oxide and an antioxidant to the rubber composition and mixing them.
