Abstract

In a tire 2, a tread 4 includes a cap layer 38 forming a part of the outer surface of the tire 2, an intermediate layer 40 disposed inwardly of the cap layer 38 in the radial direction, and a base layer 42 disposed inwardly of the intermediate layer 40 in the radial direction. A loss tangent of the intermediate layer 40 at 30°C is less than a loss tangent of the cap layer 38 at 30°C, and a loss tangent of the base layer 42 at 30°C is less than the loss tangent of the intermediate layer 40 at 30°C. An outer end PC of the cap layer 38 is disposed outwardly of an outer end PB of the base layer 42 in the axial direction. In the radial direction, a position of the outer end PC of the cap layer 38 coincides with a position of the outer end PB of the base layer 42, or the outer end PC of the cap layer 38 is disposed inwardly of the outer end PB of the base layer 42.
