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, at least the intermediate portion being only disposed inward of a tire maximum width position in the tire radial direction; and a ratio of a total width (SW) to an outer diameter (OD) satisfying the relationship SW/OD≤0.3.

A pneumatic vehicle tire has a nominal tire cross-sectional height H of at most 110 mm, bead regions with bead cores, a radial carcass which runs around the bead cores in the bead regions axially on the inside to axially on the outside forming carcass turn-ups, and side wall regions, which each have a wing profile and a side wall profile. The wing profiles are the only rubber components extending in contact with the radial carcass in the radially outer region of the side wall region. The carcass turn-ups end at a radial height (h.sub.1), determined from a base line, of 15 mm to 65 mm. At least in a region between a radial height (h.sub.2) of 29% of the nominal side wall height and a radial height (h.sub.3) of at least 80% of the height H, the wing profiles are the only rubber components that extend outside the radial carcass.

A tire 1 for a motorcycle comprises a tread portion 2 provided on an inner surface 2Si thereof with a sealant layer 11 for preventing puncture. In each half of a cross-sectional view of the tire 1, when the tread portion 2 is virtually divided into a center region 2C, a middle region 2M, and a shoulder region 2S, a thickness tm of the sealant layer 11 in the middle region 2M is larger than a thickness tc of the sealant layer 11 in the center region 2C.

A heavy-duty tire includes a tread portion including a pair of tread edges and a tire equator located therebetween. In a tire cross-section including a tire axis under a 5% inner pressure condition where the tire is mounted on a standard wheel rim with 5% of a standard pressure but loaded with no tire load, the tread portion has a profile which includes a first profile including the tire equator, a pair of second profiles extending axially inwardly from the tread edges and a pair of third profiles connecting the first profile and the respective second profiles. The first profile and the second profiles are configured as arc shapes protruding outwardly in a tire radial direction, and the third profiles are configured as straight shapes.

At a run-flat tire, given that an average radius of curvature of a case line between an intersection point (0.1 SHp) and an intersection point (0.2 SHp) when viewed in a cross-section along a tire rotation axis is radius R1, and that an average radius of curvature of the case line between an intersection point (0.4 SHp) and an intersection point (0.6 SHp) when viewed in the cross-section along the tire rotation axis is radius R2, ratio R2/R1 is set to be greater than 0.3.
