The inclined belt includes a high-angle inclined belt layer in which the cords are at an inclination angle of 35° to 90° relative to the tire circumferential direction. In at least one tread half portion, an edge of the high-angle inclined belt layer in the tire width direction is positioned further outward in the tire width direction than the circumferential main groove disposed furthest outward in the tire width direction. The interval in the tire width direction from the edge to the center of the circumferential main groove is 0.2Wto 0.35W, where Wis the width of the high-angle inclined belt layer in the tire width direction.
