PURPOSE: A rubber composition for tire is provided to improve rolling resistance and/or wear performance while not degrading hardness and tensile properties. CONSTITUTION: A rubber composition for tire includes, based on 100 parts by weight of a base rubber, 1~50 parts by weight of processing oil including alkyl phenol disulfide components. The alkyl group of alkylphenol disulfide is C1-20 alkyl group. The processing oil is modified natural oil obtained by putting 2~9 weight% of alkyl phenol disulfide into natural oil, and reacting them at 140~160°C for 8~10 hours to modify natural oil.
