Abstract
A protrusion portion () of a pneumatic tire is formed by a plurality of protrusion parts () extended along a tire circumferential direction. The protrusion parts () are arranged with predetermined gaps therebetween so as to form a circle along the tire circumferential direction. A length (S) of the protrusion part () in the tire circumferential direction is larger than a maximum width (W) of the protrusion part () in a tire radial direction. In a tire side view, a narrow groove () extended along the tire circumferential direction is formed on a surface () of the protrusion part ().
