To provide a tire in which a thickness of each portion constituting a tire of a base tire, cushion rubber as an adhesion layer, and tread rubber as a tread portion, etc. is set to an optimum range, and in which resistance performance against damage to a tread surface of the tread rubber and belt or generation heat resistance performance of the tire is not deteriorated.

A tire includes: a base tire, to an inner circumferential surface side of which a belt layer is integrated and which has a base portion; and a tread portion, which is integrated with the base portion via an adhesion layer and at an outer circumferential side of which circumferential main grooves are formed. A thickness is set to satisfy a relationship of B≤A and B≤C1, where a thickness dimension from a groove bottom of the circumferential main grooves of the tread portion to a surface of the adhesion layer is denoted by A, that of the adhesion layer by B, and the minimum thickness dimension of a thickness dimensions C between a belt layer surface and inner circumferential surface of the adhesion layer in a base portion by C1.
