Abstract
The rubber composition for tire tread and a tire includes 100 parts by weight of a raw material rubber that includes 20 parts by 80 parts by weight of a first solution polymerized styrene-butadiene rubber (SBR1) having a styrene content of 15% to 25% by weight and a vinyl content in the butadiene of 60% to 65% by weight and produced by a batch method; and 60 parts to 90 parts by weight of a silica having a specific surface area measured by nitrogen adsorption of 155 m2/g to 185 m2/g and a CTAB value of 150 m2/g to 170 m2/g.
