摘要：
A pneumatic radial tire having an excellent resistance to uneven wear is provided by optimizing a crown profile of a tread portion, in which at least a radial half section of the crown profile with respect to an equatorial plane of the tire is divided into center and middle and shoulder regions and comprised of a composite arc formed by smoothly connecting at least three arcs having different radii of curvature to each other and each of distances and radii of curvature of these regions satisfies a particular relation.
