The tread portion is provided with a crown tread profile having a radius of curvature, a middle tread profile having a radius of curvature, and a shoulder tread profile having a radius of curvature which satisfy a magnitude relation Rc>Rm>Rs. First interconnecting positions at which the crown tread profile connects with the middle tread profiles are positioned in the respective middle land regions. Second interconnecting positions at which the middle tread profiles connect with the shoulder tread profiles are positioned in the respective shoulder land regions and axially inside the inner ends of the shoulder rug grooves.
