Pneumatic tire

A pneumatic tire comprising:

• a tread portion with tread edges, and
• a pair of sidewall portions extending radially inwardly from the respective tread edges, wherein
• one of or alternatively each of the sidewall portions is provided in a radially outer part thereof with first protrusions and circumferential ribs,
• the first protrusions are arranged in a tire circumferential direction at intervals,
• the circumferential ribs are disposed between and connect between the circumferentially adjacent first protrusions,
• the first protrusions and the circumferential ribs protrude from an outer surface of the radially outer part, and a protruding amount of the circumferential ribs is less than a protruding amount of the first protrusions, whereby the first protrusions each have side walls protruding from the above-said outer surface and extending in a tire radial direction, wherein
• second protrusions whose protruding amount is less than that of the circumferential ribs, are disposed between the circumferentially adjacent first protrusions, and
• third protrusions whose protruding amount is less than that of the first protrusions, are disposed between the circumferentially adjacent first protrusions, and wherein
• the third protrusions extend radially outwardly from the circumferential ribs.
