Abstract

A tire 2 includes a tread 4 including a cap layer 46, a base layer 50, and an intermediate layer 48. A loss tangent at 30°C of the intermediate layer 48 is lower than that of the cap layer 46. A loss tangent at 30°C of the base layer 50 is lower than that of the intermediate layer 48. A boundary, between a shoulder arc and a corner arc, included in a contour line of a tread surface 24 is a reference boundary point. The reference boundary point is located axially outward of a reference ground-contact position of the tire 2. When a shoulder land portion 32s is divided into axially inner and outer portions by a ground-contact reference line LG passing through the reference ground-contact position, a thickness ratio of the intermediate layer 48 at the axially outer portion is higher than that at the axially inner portion.
