The present invention provides a rubber composition for treads, containing: a rubber component including an isoprene-based rubber and polybutadiene rubber; silica; carbon black; a terpene-based resin; and a water-soluble fine particle and/or a foaming agent, the terpene-based resin having a softening point of 70-150° C., an α-pinene unit content of 65-100% by mass, and a β-pinene unit content of 0-35% by mass, the rubber component including, based on 100% by mass thereof, 20-80% by mass of the isoprene-based rubber and 20-80% by mass of the polybutadiene rubber, with a combined amount of the isoprene-based rubber and the polybutadiene rubber of 90% by mass or more, the rubber composition containing, per 100 parts by mass of the rubber component, 20-200 parts by mass of the silica, 0.1-50 parts by mass of the carbon black, and 0.1-50 parts by mass of the terpene-based resin.
