Abstract
A pneumatic tire includes chamfered sipes in a land portion each including a chamfered portion, and non-chamfered sipes in the land portion each not including the chamfered portion. The chamfered sipe includes one end communicating with the main groove that defines the land portion and the other end terminating within the land portion. The chamfered and non-chamfered sipes are alternately disposed in the circumferential direction. Of the non-chamfered sipes on both sides in the circumferential direction of the chamfered sipe, a relationship between a distance a and a distance b is in the range 1.5≤(b/a)≤12, where the distance a is between the chamfered sipe and a near sipe corresponding to the non-chamfered sipe located on a side closest to the chamfered sipe, and the distance b is between the chamfered sipe and the non-chamfered sipe located further from the chamfered sipe in the circumferential direction.
