  "textContent": "To provide a rubber composition for tire tread having remarkably improved wet grip performance without lowering abrasion resistance and rolling resistance property (low heat build-up characteristics), and a pneumatic tire using the same. The rubber composition for tire tread of the present invention comprises 5 to 150 parts by weight of calcium carbonate, at least 5 parts by weight of silica shaving nitrogen adsorption specific surface area of 100 to 300 m/g and at least 1 part by weight of carbon black having nitrogen adsorption specific surface area of 70 to 300 m/g based on 100 parts by weight of a rubber component, said rubber composition further comprising a silane coupling agent.",
