Provided is a pneumatic tire that provides a balanced improvement of abrasion resistance, wet grip performance, and fuel economy. A rubber composition for tires containing: a rubber component including an aromatic vinyl-conjugated diene copolymer that contains aromatic vinyl units derived from an aromatic vinyl compound and conjugated diene units derived from a conjugated diene compound; carbon black; and a silica having a N 2 SA of 40 m 2 /g or more, the copolymer containing at least 80% of isolated aromatic vinyl units based on the total aromatic vinyl units, the copolymer having a ΔTg of more than 10° C. but less than 20° C. as determined by DSC, the rubber component including, based on 100% by mass thereof, 1-90% by mass of the copolymer and 0-70% by mass of an isoprene-based rubber, the rubber composition containing 10 parts by mass or more of the silica per 100 parts by mass of the rubber component. |
