Abstract
The present technology provides a rubber composition containing: a diene-based rubber containing a natural rubber and a butadiene rubber; a carbon black 1; and a carbon black 2. A nitrogen adsorption specific surface area of the carbon black 1 is from 60 to 100 m2/g; a dibutyl phthalate oil absorption of the carbon black 1 is 120 cm3/100 g or less; a nitrogen adsorption specific surface area of the carbon black 2 is from 20 to 40 m2/g; a dibutyl phthalate oil absorption of the carbon black 2 is from 70 to 95 cm3/100 g; and a total amount of the carbon black 1 and the carbon black 2 being from 25 to 50 parts by mass per 100 parts by mass of the diene-based rubber.
