TIRE

A pneumatic tire (10) includes a longitudinal ridge (110) extending along the tire radial direction and projecting outward from the surface of the tire side portion (30) toward an outside of a tire width direction. A plurality of longitudinal ridges (110) are provided along the tire circumferential direction, and a tire radial direction inner end (110 a) of the longitudinal ridge (110) is located outside the tire radial direction than the maximum width position (Wmax). The tire radial direction outer end (110 a) of the longitudinal ridge (110) is located outside the tire radial direction than a straight line L2 orthogonal to a straight line L1.
