TIRE

The tire includes a lateral groove (30) formed in a tread section (10) and extending in a tire width direction (TW). One groove wall (31) forming the lateral groove (30) includes an inclined surface (32) with curved shape. The inclined surface (32) has an inclination angle (θ), the inclination angle (θ) being an angle with respect to a tire radial direction (TR) from a groove bottom (33) to a tread surface (35) in a cross section perpendicular to a tire axial direction (TA), that gradually increases from an inner side in the tire width direction on a tire equatorial line (CL) side to an outer side in the tire width direction.
