Abstract

Provided is a tire comprising a tread part, wherein the tread part is composed of a rubber composition comprising a rubber component, a filler, and a plasticizer, wherein the rubber component comprises a styrene-butadiene rubber, wherein the filler comprises carbon black, wherein the plasticizer comprises a resin component, wherein a radius of curvature R of the tread part on a tire equator is 50 mm or more and 220 mm or less, and wherein Dt, 100°C tan δ, and 100°C E* satisfy the following inequality (1): 9.0×100°Ctanδ−1.0×103×100°CE*/Dt>0 where Dt represents a tire outer diameter, in mm, 100°C tan δ represents a tan δ at 100°C of the rubber composition, and 100°C E* represents a complex elastic modulus, in MPa, at 100°C of the rubber composition.
