Abstract

Provided are a rubber composition, for a tire, having significantly improved combined performance of low fuel consumption performance and chip-cut resistance, and a pneumatic tire produced using the rubber composition. The rubber composition for a tire contains an isoprene-based rubber, a butadiene rubber, a styrene-butadiene rubber having a styrene content of 18 to 40% by mass, a carbon black having an iodine adsorption amount not less than 130 mg/g, and silica. In 100% by mass of a rubber component, an amount of the isoprene-based rubber is not less than 40% by mass, an amount of the butadiene rubber is not less than 20% by mass, and an amount of the styrene-butadiene rubber is 1 to 30% by mass. An amount of the silica per 100 parts by mass of the rubber component is 5 to 60 parts by mass.
