Abstract

It is an object of the present invention to provide a tire having improved overall performance of high-speed turning performance and fuel efficiency. Provided is a tire having a tread part (4) and a belt layer (3), wherein a rubber composition of the tread part comprises a rubber component and a thermoplastic elastomer, wherein the rubber component comprises a multicomponent copolymer having an aromatic vinyl unit and a conjugated diene unit, wherein the thermoplastic elastomer comprises a styrene-based thermoplastic elastomer having an alkylene unit, wherein, when Y is defined in the following equation with Wt, in mm, being a cross-sectional width of the tire and B, in mm, being a belt layer width of the tire under a condition that a tread of the tire in a standardized state is pressed against a flat surface by applying a standardized load, Y=(B-16)/Wt, Y is 0.75 or less, and wherein a ratio (X/Y) of a total content X, in part(s) by mass, of the thermoplastic elastomer based on 100 parts by mass of the rubber component to Y is 3.0 or more.
