摘要： A heavy duty tire 1 has a carcass extending from a tread portion 2 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 2 is formed by a 1st circular arc C1 having a center O1 on the tire equatorial plane C, and a pair of 2nd circular arcs C2, C2 disposed on both outsides of the 1st circular arc C1 in the tire axial direction. The radius R2 of the 2nd circular arc C2 is more than the radius R1 of the 1st circular arc C1. One 2nd circular arc C2 has the center O2 on the other 2nd circular arc C2 side of the tire equator C in the tire axial direction, and the other 2nd circular arc C2 has the center O2 on the one 2nd circular arc C2 side of the tire equator C in the tire axial direction.
