    摘要: Disclosed is a rubber composition wherein 1-10 parts by mass of sulfur and 0.1-10 parts by mass of a compound represented by the general formula (1) below or a composition mainly containing such a compound are compounded per 100 parts by mass of a rubber component. Also disclosed is a pneumatic tire wherein at least one of a carcass (4) and a belt (6) includes a layer which is composed of a steel cord covered with a coating rubber, which pneumatic tire is characterized in that the above-described rubber composition is used as the coating rubber covering the steel cord in at least one of the carcass (4) and the belt (6). (1) (In the formula, R represents a divalent aliphatic group having 1-16 carbon atoms or a divalent aromatic group.)
