RUBBER COMPOSITION FOR TIRE TREAD

摘要

A rubber composition for a tire tread comprising a novel modified styrene-butadiene copolymer rubber, carbon black, and aromatic oil. The improved rubber composition results in a tire tread with a low heat build-up, an improvement in blowout resistance and improved abrasion resistance, while keeping excellent processability and high grip performance, over tires of conventional rubber composition. This rubber composition is suitably utilized particularly in treads of high performance tires and racing tires used in races, rallies and the like.
