PROBLEM TO BE SOLVED: To provide a rubber composition for a tire tread having improved dispersibility, processability, mechanical characteristics, wear resistance and rotational resistance characteristics, and to provide a tire produced by using the same.SOLUTION: There is provided a rubber composition for a tire tread which comprises 10 to 100 pts.wt. of a reinforcing filler and 1 to 20 pts.wt. of a silane compound 1 represented by the following formula based on 100 pts.wt. of a raw material rubber, wherein the raw material rubber contains 40 to 90 pts.wt. of a styrene butadiene rubber and 10 to 60 pts.wt. of a butadiene rubber. (Wherein, X to Z, a to c and x are as defined in the description.) |
