An intersection of an extended line of a shoulder side arc and an extended line of a side portion arc is a reference point P, an aspect ratio is β, and an angle θ formed by a straight line A joining the reference point P and a center crown CC and a straight line B in a tire width direction that passes through the center crown CC is configured such that 0.025×β+1.0≰θ≰0.045×β+2.5. A curvature radius Rc of a center portion arc and a curvature radius Rs of the shoulder side arc are configured such that 12≰Rc/Rs≰30. A reference developed width L from a tire equatorial plane CL to an edge of the shoulder side arc on a tire width direction inner side and a developed tread width TDW are configured such that 0.2≰L/(TDW/2)≰0.7.
