Abstract
Disclosed is a rubber composition for tire treads and a tire manufactured using the same. More particular, the rubber composition for tire treads includes 50 to 200 parts by weight of a wet masterbatch prepared by reacting a styrene-butadiene latex, a carbon black and a liquid styrene-butadiene copolymer at 50 to 95° C. for three to nine hours according to a batchwise method, 60 to 70 parts by weight of a raw rubber, and 50 to 200 parts by weight of a carbon black. Accordingly, the rubber composition for tire treads has enhanced grip and anti-wear performances under a condition of heavy load, high slip and high speed, and thus, may be usefully used in manufacturing a ultra-high performance tire.
