Provided are a rubber composition for a tread, capable of improving the fuel economy and abrasion resistance in a balanced manner while achieving a good appearance and a good cure rate; and a pneumatic tire containing the rubber composition. The present invention relates to a rubber composition for a tread, including: a solution-polymerized styrene-butadiene rubber, carbon black, silica, and polyethylene glycol, wherein a rubber component of the rubber composition contains 60 mass % or more of the solution-polymerized styrene-butadiene rubber based on 100 mass % of the rubber component, and the rubber composition includes, per 100 parts by mass of the rubber component, 10 parts by mass or less of the carbon black, 50 parts by mass or more of the silica, and 0.1 to 3.5 parts by mass of the polyethylene glycol. |
