On an outer contour of the tire as viewed in a cross section along the rotation axis of the tire, the ground contact angle θ of the tangential line of the small arc portion at a height of 80% of the cross sectional height SH of the tire, with respect to the axial direction of the tire, is set within a range of 47-52°.
