Zusammenfassung:A tire includes a tread portion provided with at least one circumferentially and continuously extending shoulder main groove and at least one circumferentially and continuously extending crown main groove. The at least one crown main groove extends in a straight manner in a tire circumferential direction. The at least one shoulder main groove includes narrow segments inclined at angles with respect to the tire circumferential direction and wide segments each having widths greater than widths of the narrow segments. The narrow segments and the wide segments are arranged alternately in the tire circumferential direction so as to form a zigzag groove shape, wherein the widths of the narrow segments are in a range of from 5% to 7% of a tread width.
