The cap rubber layer includes a crown cap portion disposed in a middle region in the tire axial direction of a tread portion and a pair of shoulder cap portions disposed in both sides in the tire axial direction of the crown cap portion. The crown cap portion has a loss tangent tan δc, the shoulder cap portions have a loss tangent tan δs, and the base rubber layer has a loss tangent tan δb, wherein the loss tangents tan δc, tan δs and tan δb satisfy the following equation (1): tan δc",
