A tire comprising a tread part comprising at least one rubber layer and a sidewall, wherein each of the tread part and the sidewall is composed of a rubber composition comprising a rubber component and a vegetable oil, wherein, an average value of a contents of the vegetable oil based on 100 parts by mass of the rubber component in the tread rubber is greater than a content of the vegetable oil based on 100 parts by mass of the rubber component of the rubber composition constituting the sidewall, and wherein, when a complex elastic modulus at 30°C of a cap rubber layer constituting a tread surface is defined as 30°CE∗, in MPa, and a complex elastic modulus at 70°C of the rubber composition constituting the sidewall is defined as 70°CE∗, in MPa, 30°CE∗ - 70°CE∗ is 3.0 MPa or less.
