An uneven wear-resisting heavy duty pneumatic tire comprises main grooves (1) continuously extending in the tread of the tire along the circumference thereof, land portions (2) separated by the main grooves, and stepped zones (3) each provided in the land. Each stepped zone has a surface located radially inside of the tread by a step as viewed sectionally. Each of said stepped zones is separated from the adjacent land portions via a pair of circumferentially extending narrow grooves (4) or cuts. An uneven wearing-sacrificing portion is formed by the surface of the stepped zone. The uneven wear-sacrificed portion slide-contacts with the tread within the tread ground-contacting area for supporting the load exerted upon the tire. (Figure 1b).
