A pneumatic tire including: a circumferential groove partitions a contact patch; and a protrusion that protrudes from a base of the circumferential groove and that interconnects two groove sidewalls at either side in a groove width direction of the protrusion. As seen in plan view, at least one of the two groove sidewalls at either side in the groove width direction of the protrusion has a first region that is adjacent to the protrusion, second regions that are present to either side in the groove long direction of the first region, and a first chamfered region that serves as beveling and that is formed at the first region. Presence of the first chamfered region causes an edge where the contact patch and the groove sidewall of the first region intersect to be more relieved than an edge where the contact patch and the groove sidewall of the second region intersect.
