ABSTRACT:
A pneumatic tire for heavy load enabling the co-existence of wet performance and uneven wear resistance performance is provided. The pneumatic tire for heavy load includes three circumferential main grooves31and33extending on a tread in the circumferential direction, and ribs11and12defined by these circumferential main grooves31and33. The centerline of the center circumferential main grove31among the three circumferential main grooves is positioned on the equator line of the tread, and a thin rib-shaped uneven abrasion sacrificing part (BCR)21having a step in a clearance thereof from the surface of the tread is formed only in the center circumferential main groove31.
