A pneumatic tire (10) has: an outer layer (36) that structures rubber of a tread (18); an inner layer (38) that is layered at a tire radial direction inner side of the outer layer (36), that structures rubber of the tread (18), and that has a different wear characteristic from the outer layer (36); and a boundary surface (40) that structures a border of the outer layer (36) and the inner layer (38), and that, in a tire radial direction cross-section seen from a tire axial direction, has wave shapes having an amplitude in a tire radial direction.",
