Abstract: A pneumatic tire comprises a tread portion provided with tread grooves defining a asymmetrical tread pattern. The tread grooves include an outboard shoulder main groove and an outboard crown main groove extending zigzag continuously in the tire circumferential direction. The outboard shoulder main groove is composed of alternate long groove segments and short groove segments which are inclined with respect to the tire circumferential direction to the outboard tread edge. The inclination angle ?b of the short groove segments is larger than The inclination angle ?a of the long groove segments. The groove widths of the long groove segments are gradually increased toward the outboard tread edge.
