Patent ID: 8689847

Claim:
A pneumatic tire comprising a plurality of radial protrusions each extending in a tire radial direction on a tire surface and having a shape protruding from the tire surface outward in a tire width direction, wherein the plurality of radial protrusions are provided radially with a tire rotation axis as a center, the plurality of radial protrusions each have a low protrusion portion and more than one high protrusion portion, and a height of the low protrusion portion measured in the tire width direction is lower than a maximum height of the high protrusion portions measured in the tire width direction, wherein the low protrusion portion is positioned in between a first high protrusion portion and a second high protrusion portion in the tire radial direction, wherein the height of the low protrusion portion measured in the tire width direction is 0.2 times to 0.8 times, both inclusive, of the maximum height of the high protrusion portions measured in the tire width direction, wherein the low protrusion portion is provided to the tire surface in a tire maximum width portion in the tire width direction, and wherein the pneumatic tire further comprises a circular circumferential protrusion extending along a circumference which has the tire rotation axis as a center, and having a shape protruding from the tire surface outward in the tire width direction, wherein part of the circular circumferential protrusion constitutes the low protrusion portion of each of the plurality of radial protrusions.
