A rubber composition for a tire tread with improved wear resistance and heat resistance and a tire obtained using the rubber composition. SOLUTION: To 100 parts by weight of a rubber component containing 5 to 100% by weight of epoxidized natural rubber, 5 to 150 parts by weight of silica having a nitrogen adsorption specific surface area of 100 to 300 m 2 / g, and 1 metal stearate salt. A rubber composition for a tire tread containing 1 to 20 parts by weight of a silane coupling agent represented by the following formula with respect to 100 parts by weight of silica and 100 parts by weight of silica. (C n H 2n + 1 O ) 3 -Si- (CH 2) m -S l - (CH 2) m -Si- (C n H 2n + 1 O) 3 (In the formula, n is an integer of 1 to 3, m is an integer of 1 to 4, and l represents the number of sulfur atoms in the polysulfide part) [Selection figure] None |
