Abstract

Provided is a pneumatic tire (10) having a tread (20) including a block (30) in which a sipe (40) is formed. In this pneumatic tire (10), at least one wall surface (41) of the sipe (40) is formed in a waveform including a plurality of curved portions (42) extending from a block surface side to a block bottom side when viewed from a tire radial direction (Z). The curved portions (42) include an inwardly curved portion (42A) that bulges toward the inside of the sipe (40) and an outwardly curved portion (42B) that bulges toward the outside of the sipe (40). The radii of curvature of the inwardly curved portion (42A) and the outwardly curved portion (42B) differ on the block surface side in the tire radial direction (Z), and the radii of curvature of the inwardly curved portion (42A) and the outwardly curved portion (42B) are identical on the block bottom side.
