The present invention relates to a manufacturing tires using the rubber composition, and this, for a tire tread, the raw material rubber 100 parts by weight of a petroleum-base oil 0-5 parts by weight, and C 9 modified petroleum resin C 5 petroleum resins, acrylated C 5 petroleum resin, and 5 to 10 parts by weight of any one petroleum resin selected from the group consisting of combinations thereof. The rubber composition for a tire tread can improve hardness and modulus in the initial strain region, improve braking performance on a dry road surface, and maintain the rolling resistance performance at the same level. |
