Abstract

PURPOSE: A tread rubber composition that is made by adding reinforcing carbon black and aromatic process oil to a mixture of specific rubbers different in styrene content, then vulcanizing them, thus showing improved cutting, chipping and wearing resistances.
CONSTITUTION: To (A) 100 parts by wt of a rubber mixture consisting of 95W50 parts of a rubber selected from butadiene-styrene rubber of over 30wt% styrene content, butyl rubber, and halogenated butyl rubber and 5W50 parts of another rubber selected from butadiene-styrene rubber of 18W28wt% styrene content, natural rubber, polyisobutylene rubber, polybutadiene rubber, ethylene-propylenediene terpolymer rubber are added (B) 60W100 parts of high reinforcing carbon black with an iodine adsorption of 130W150mg/g and a tinting power of over 240% and (C) 20W60 parts of an aromatic process oil with a viscosity/density ratio of over 0.84 and they are vulcanized.
