Provided are a rubber composition for tires that provides a balanced improvement of snow and ice performance and abrasion resistance, and a tire including the rubber composition. The rubber composition for tires contains: a rubber component including an isoprene-based rubber and BR; silica; and a terpene-based resin having a softening point of 60-150°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 component including, based on 100% by mass thereof, 5-80% by mass of the isoprene-based rubber and 5-80% by mass of the BR, with a combined amount of the isoprene-based rubber and the BR of 60% by mass or more, the rubber composition containing, per 100 parts by mass of the rubber component, 1-500 parts by mass of the silica and 0.1-100 parts by mass of the terpene-based resin. |
