摘要: Heavy duty pneumatic tire with a tread portion having a zigzag crown main groove and a pair of zigzag shoulder main grooves forming two crown land portions between the crown main groove and two shoulder main grooves. The crown land portion is divided by crown lateral grooves into circumferentially arranged crown blocks. The crown lateral grooves in each crown land portion extend from alternate axially inside zigzag vertices of the shoulder main groove to zigzag vertices of the crown main groove, while inclining with respect to the tire circumferential direction. The crown block has a crown auxiliary groove narrower in width than the crown main groove and extending to one of the zigzag vertices of the crown main groove to which none of the crown lateral grooves are connected, from one of the inside zigzag vertices of the shoulder main groove, while inclining with respect to the tire axial direction.

A pair of middle land sections in the tread is positioned between the shoulder and center grooves. Each of the shoulder and center grooves has a groove width set in range of 7 to 9% of width of the tread footprint. An outer middle land portion is divided into first and second middle land portions by a middle narrow groove. The first land portion forms rib. The second land portion has outer middle lateral grooves connected to the center groove and the narrow groove. Each lateral groove includes first portion, second portion having the opposite inclination to the first portion and connection portion between the first and second portions.
