ABSTRACT:
A heavy duty pneumatic tire comprises a tread, two side walls, two beads, a radial carcass reinforcement, and a belt composed of at least two plies of which cords are intersected in the adjacent plies. The radius of curvature of the contour of the tread appearing in a tire cross section including a tire rotary axis is asymmetrical with respect to the tire equatorial plane. A larger radius of curvature is given to the tread portion to be located outside when the tire is mounted to a wheel, while a smaller radius of curvature is given to the tread portion to be located on the inner side when the tire is mounted to the wheel. The difference between the larger radius of curvature and the smaller radius of curvature is not less than 70 mm. The rigidity of the tread is larger on the tread portion having the larger radius of curvature than on the tread portion having the smaller radius of curvature.
