To provide a pneumatic tire enhancing appearance property after development of friction while suppressing eccentric abrasion developed from a shoulder part end.
The pneumatic tire is provided with a plurality of layers of belt layer 11; and a tread 12 arranged at an outer side in the tire radial direction and provided with a plurality of circumferential main grooves 1 on a crown part. A large number of sipes 2 directed to a tire radial direction are formed on a buttress part 13 continued to an end of the tread 12, and an upper end of the sipe 2 is positioned in a range of 30-100% of depth D of the circumferential main groove 1. Length h opened to a surface of the buttress part of the sipe 2 is 5-150% of the depth D of the circumferential main groove 1, and depth t of the sipe 2 is within a range of 0.5-10% of tread width.
