Abstract
A pneumatic tire comprises a plurality of protrusion portions extending along a tire side surface of a tire side portion in a direction that intersects a tire circumferential direction and a tire radial direction; the plurality of protrusion portions each including an intermediate portion in an extension direction that includes a highest position of projection height from the tire side surface, and tip portions on either side of the intermediate portion in the extension direction that include a lowest position of projection height from the tire side surface; and at least the intermediate portion being only disposed outward of a tire maximum width position in the tire radial direction.

A pneumatic tire, comprising:
- a plurality of protrusion portions extending along a tire side surface of a tire side portion in a direction that intersects a tire circumferential direction and a tire radial direction;
- the plurality of protrusion portions each including
- an intermediate portion in an extension direction that includes a highest position of projection height from the tire side surface, the intermediate portion being defined as in a range of 25% of a length of the protrusion portion in the extension direction from a center on either side in the extension direction, and
- tip portions on either side of the intermediate portion in the extension direction that include a lowest position of projection height from the tire side surface, the tip portions extending from the intermediate portion on both sides in the extension direction excluding 5% of the length L of the protrusion portion from ends of the protrusion portion in the extension direction;
- and
- at least the intermediate portion being only disposed outward of a tire maximum width position in the tire radial direction;
- wherein
- the lowest position at the tip portion is at a position 5% of the length L of the protrusion portion from the ends of the protrusion portion,
- the projection height of the protrusion portion at the lowest position is smaller than the projection height of the protrusion portion at the highest position,
- the projection height of the protrusion portion in the extension direction gradually increases from one of the ends of the protrusion portion toward the center and gradually decreases from the center toward an other one of the ends of the protrusion portion, and
- when the pneumatic tire is mounted on a regular rim, inflated to a regular internal pressure, in an unloaded state, and viewed in a meridian cross-section, the protrusion portion projects outward 5 mm or less in a tire lateral direction from a tire cross-sectional width at the tire maximum width position.
