Abstract
A pneumatic tire wherein a sipe includes protrusions on a first sipe wall face of mutually opposing sipe wall faces and recesses that mate with the protrusions in a second sipe wall face. Additionally, in a projection figure of the protrusions with the sipe wall faces in an expanded state, a relationship between a placement density X of the protrusions in a region that extends up to half of a sipe depth H from an opening of the sipe and a placement density Y of the protrusions in a region that extends up to half of the sipe depth H from a bottom of the sipe is X>Y.
