A rubber composition comprises 5 to 30 parts by mass of a terpene resin having a softening point of 100 to 120° C. and a molecular weight of 500 to 10,000, and 2 to 10 parts by mass of a liquid rubber or a liquid resin having a molecular weight of 100 to 3,500, based on 100 parts by mass of a rubber component comprising 72 to 95% by mass of an aromatic olefin rubber and 5 to 28% by mass of a diene olefin rubber, wherein a ratio of a content of the terpene resin to a content of the liquid rubber or the liquid resin (a content of the terpene resin/a content of the liquid rubber or the liquid resin) is from 0.5 to 5, and the tire is one having a tire member composed of the rubber composition.
