The present invention relates to a rubber composition for a tire tread, the rubber composition comprising 100 parts by weight of a raw material rubber, 10 to 30 parts by weight of a vegetable oil having a weight ratio of linolenic acid to oleic acid of 1:0.5 to 1:1.5, 10 to 20 parts by weight of a terpene-based resin having a softening point of 110 to 130 °C, and 75 to 120 parts by weight of a reinforcing filler, and a tire manufactured using the rubber composition for the tire tread. The present invention provides a tread rubber composition for four seasons which improves the braking performance on the ice and snow road surface and the abrasion resistant performance and improves the braking performance on the wet road surface at the same time while minimizing a drop in rotational resistance.
