TIRE

It is an object of the present invention to provide a tire having excellent total performance of fuel efficiency, steering stability on a wet road, and abrasion resistance. Provided is a tire comprising a tread, wherein the tread is composed of a rubber composition comprising a rubber component, silica, and a softening agent, wherein the rubber component comprises a butadiene rubber, wherein the softening agent comprises a modified liquid butadiene rubber that is modified with a functional group that interacts with silica, wherein, when a content of the butadiene rubber after the rubber composition subjected to vulcanization is extracted with tetrahydrofuran is defined as X (% by mass), a tire cross-sectional width is defined as Wt (mm), and a tire outer diameter is defined as Dt (mm), X, Wt, and Dt satisfy specific relationships.
