Pneumatic tire

A pneumatic tire comprising:

• a narrow groove formed on a tread surface and extending in a direction inclined with respect to a tire circumferential direction, a width of the narrow groove being smaller than a depth of the narrow groove;
• an air inflow part, one end of the air inflow part opening to at least one of groove walls of the narrow groove that face each other in the tire circumferential direction, and another end of the air inflow part opening to the tread surface;
• and
• a wear prevention portion formed by a protrusion on a groove wall that faces a groove wall on which the air inflow part is formed or on the tread surface connecting to the groove wall that faces the groove wall on which the air inflow part is formed,
• wherein the air inflow part has a length of 5 mm or more along the longitudinal direction of the narrow groove and ½ or less of a length of the narrow groove along the longitudinal direction,
• at least one end of the narrow groove is a terminal end terminating in a land portion,
• the air inflow part is disposed only at the terminal end of the narrow groove, and
• the wear prevention portion is located to overlap the air inflow part in the tire circumferential direction, and wherein
• the wear prevention portion does not contact the groove wall on which the air inflow part is formed.
