PNEUMATIC TIRE

A pneumatic tire (1) comprising: a tread portion (2) is in contact with a road surface; and a side wall portion (3) is continuous to the tread portion (2) and positioned inside a tire radial direction of the tread portion (2). A large region (10) comprising a plurality of small regions (11, 12 and 13) having different arithmetic average roughness outside in a tire width direction is formed on outer surface of the side wall portion (3). A plurality of large regions (10) are formed along a tire circumferential direction and the tire radial direction. In a boundary line of adjacent large region (10), small regions having different arithmetic average roughness come into contact with each other.
