Abstract
A pneumatic tireaccording to the present invention includes a plurality of turbulence generation ridgeswhich extend on a surface of a tire side portionin a tire-radial direction and which are arranged at a pitch in a tire-circumferential direction. A protrusionrising from the surfaceof the tire side portionis formed in the tire side portion. Either an inner end portionA of the turbulence generation ridgeor an outer end portionB of turbulence generation ridgeis smoothly continuous to a surface of the protrusion. An inner end height (H), which is a height of the inner end portionA from the surfaceof the tire side portion, is larger than an outer end height (H), which is a height of the outer end portionB from the surfaceof the tire side portion
