Rubber Composition for Tire Tread and Tire Manufactured by Using the Same

摘要

Disclosed is a rubber composition for tire treads and a tire manufactured using the same. The rubber composition for tire treads includes 50 to 200 parts by weight of a wet masterbatch, 60 to 70 parts by weight of a raw rubber, and 50 to 200 parts by weight of a carbon black, the wet masterbatch being prepared by reacting 50 to 200 parts by weight of a carbon black, 20 to 100 parts by weight of a plant based resin and 50 to 200 parts by weight of a processing oil with respect to 100 parts by weight of a styrene-butadiene latex, according to a batchwise method. Accordingly, high grip performance is exhibited under a condition of heavy load, high slip and high speed, thereby being applicable to an ultra-high performance tire.
