The present invention provides a rubber composition for tires that provides a balanced improvement of grip performance, fuel economy, and abrasion resistance. Included is a rubber composition for tires, containing a rubber component and a terpene-based resin, the rubber component including, based on 100% by mass thereof, 5-100% by mass of styrene butadiene rubber and 0-80% by mass of polybutadiene rubber, with a combined amount of the styrene butadiene rubber and the polybutadiene rubber of 80% by mass or more, the terpene-based resin having a softening point of 70-150°C, an α-pinene unit content of 65-100% by mass, a β-pinene unit content of 0-35% by mass, and a limonene unit content of 10% by mass or lower, the rubber composition containing, per 100 parts by mass of the rubber component, 0-500 parts by mass of silica and 0.1-100 parts by mass of the terpene-based resin.
