The present invention relates to a rubber composition for a tire tread and a tire manufactured therewith. The rubber composition includes: 100 parts by weight of a raw material rubber including 20 to 50 parts by weight of a continuous solution polymerization styrene-butadiene rubber, 20 to 50 parts by weight of a batch solution polymerization styrene-butadiene rubber, and 10 to 40 parts by weight of a neodymium-butadiene rubber; 60 to 90 parts by weight of silica; and 1 to 5 parts by weight of a processing aid including a saturated fatty acid amide containing a calcium salt and a mixture of a saturated fatty acid ester. The rubber composition for a tire tread solves the problem of processability according to introduction of a material with difficult workability and improves low rolling resistance and wear resistance characteristics. |
