In a pneumatic tire, a pair of width-oriented sipes that straddle one of circumferential recessed regions are arranged in such fashion as to appear to partially mutually overlap as viewed in a tire width direction, each of the pair of width-oriented sipes comprises a sipe portion at which width is constant, and a notch portion at which width increases toward the exterior in a tire radial direction, the sipe portion is such that at least one end thereof is contiguous with at least one of the circumferential recessed regions in such fashion as to be inclined with respect to the at least one circumferential recessed region; and the notch portion is arranged at a corner at which the sipe portion intersects the at least one circumferential recessed region to form an acute angle therebetween.
