Heretofore, there has been proposed a pneumatic tire in which a shoulder land portion defined between a shoulder main groove and a tread edge is provided with a shoulder lug groove extending from the tread edge toward the inside in the tire axial direction and terminating without reaching the shoulder main groove (for example, see Patent Document 1). Such pneumatic tire can improve the steering stability because it is possible to increase the circumferential rigidity of the shoulder land portion.
