The present invention relates to a rubber composition for a tire tread and a tire manufactured using the same, comprising 40 to 80 parts by weight of an emulsion-polymerized styrene-butadiene rubber (E-SBR), a Si-coupled solution-polymerized styrene-butadiene rubber (S- SBR) 100 parts by weight of raw rubber, including 10 to 40 parts by weight, and 10 to 30 parts by weight of nickel butadiene rubber having a sheath content of 96% by weight or more and a glass transition temperature of -105 to -110 ° C, and 30 to 50 weight of silica. Parts, and 30 to 50 parts by weight of carbon black. The rubber tread rubber composition is environmentally friendly and can improve workability in the unvulcanized state, improve wet braking performance in the vulcanized state and at the same time reduce the rolling resistance. |
