Abstract
A heavy duty tire has a carcass extending from a tread portion to a bead core in a bead portion through a sidewall portion, and a belt layer disposed on the outside of the carcass in the tire radial direction and on the inside of the tread portion. In a state in which a distance between a pair of bead heels is kept at 110% of a wheel rim width of a standard wheel rim and no inner pressure is applied, the contour shape of the tread portion is formed by a 1st circular arc having a center on the tire equatorial plane, and a pair of 2nd circular arcs, disposed on both outsides of the 1st circular arc in the tire axial direction. The radius of the 2nd circular arc is more than the radius R1 of the 1st circular arc. One 2nd circular arc has the center on the other 2nd circular arc side of the tire equator in the tire axial direction, and the other 2nd circular arc has the center on the one 2nd circular arc side of the tire equator in the tire axial direction.
