PNEUMATIC TIRE FOR HEAVY LOAD

摘要

A pneumatic tire for heavy load enabling the co-existence of wet performance and uneven wear resistance performance, comprising three peripheral main grooves (31) and (33) extending in the circumferential direction of a tread and ribs (11) and (12) defined by these circumferential main grooves (31) and (33). The centerline of the center circumferential main groove (31) among three circumferential main grooves is positioned on the equator line of the tread, and a thin rib-shaped uneven abrasion sacrificing part (BCR) (21) having a step in the clearance thereof from the surface of the tread is formed only in the center circumferential main groove (31).
