A rubber composition, for tires, which allows improvement of both wet grip performance and performance on ice and snow, and further allows abrasion resistance and elongation at break to be advantageously obtained, and a pneumatic tire using the rubber composition, are provided. A rubber composition for tires is provided in which a content of an isoprene-based rubber in 100% by mass of a rubber component ranges from 10% by mass to 100% by mass, a content of a butadiene rubber in 100% by mass of the rubber component ranges from 0% by mass to 80% by mass, a content of a styrene butadiene rubber in 100% by mass of the rubber component ranges from 0% by mass to 70% by mass, and a content of a terpene-based resin having a hydroxyl value that is less than or equal to 20 and a softening point ranging from 106°C to 124°C ranges from 1 part by mass to 50 parts by mass, per 100 parts by mass of the rubber component. |
