Abstract
A rubber composition containing a butadiene rubber in an amount of 60% by mass or more relative to the total amount of a rubber component therein, and containing, relative to 100 parts by mass of the rubber component, a carbon black having an iodine adsorption of 100 to 170 g/kg and a DBP oil absorption of 100 to 140 cm3/100 g, in an amount of 40 to 70 parts by mass, sulfur in an amount of 0.3 to 2.0 parts by mass, and a vulcanization accelerator in an amount of 1.5 to 3 parts by mass.
