In a pneumatic tire, a plurality of side blocks include a first side block which is contiguous with the exterior in a tire axial direction of a first tread block, and a second side block which is contiguous with the exterior in the tire axial direction of a second tread block; the first side block comprises a first apical surface which is arranged at an outer end of the first side block in the tire axial direction; the second side block comprises a second apical surface which is arranged at an outer end of the second side block in the tire axial direction, and area of the second apical surface is greater than area of the first apical surface.

A pneumatic tire includes a tread portion having a first tread edge, and a first buttress portion extending inwardly in a tire radial direction from the first tread edge. The first buttress portion is provided with a plurality of protectors protruding outwardly in a tire axial direction. Each of the plurality of protectors includes a top surface facing outwardly in the tire axial direction, and a side surface extending inwardly in the tire axial direction from an edge of the top surface. The side surface includes an outward-facing portion facing outwardly in the tire radial direction, an inward-facing portion facing inwardly in the tire radial direction, and a circumferential portion facing in a tire circumferential direction. The outward-facing portion, the inward-facing portion and the circumferential portion have different angles with respect to respective normal lines of the top surface from each other.

A pneumatic tire includes a plurality of protrusions that are provided in a range that includes the tire maximum width position of the tire side portion, and that extend in a direction intersecting the radial direction. The plurality of protrusions are separated from each other in the tire circumferential direction by spacings, pass through the center of rotation of the tire, and extend in the tire radial direction. In a case where a first straight line and a second straight line with different tire circumferential direction positions each cross the protrusions, a ratio of a sum of masses per unit length of the protrusions the first straight line crosses to a sum of masses per unit length of the protrusion the second straight line crosses is not less than 0.8 and not greater than 1.2.

The present disclosure provides a tire having excellent durability during high speed running. A tire including a sidewall portion including a thermoplastic elastomer composition having a specific heat capacity of 1.7 J/ (g .Math.K) or less, the tire having a depression with a depth of 0.2 to 3.0 mm and/or a projection with a height of 0.2 to 3.0 mm between the tread ground contact edge and the tire maximum width position of the sidewall portion.

A pneumatic tire has a side wall having a side surface and dimples formed on the side surface. The side surface has the tire maximum width point, the dimples are aligned along circumferential rows in concentric form with respect to the tire axis such that the dimples form lateral ribs and longitudinal ribs, the lateral ribs each have radially outer side surface and radially inner side surface and include first and second ribs, the first rib is formed such that the height from the dimple bottom at the inner side surface and the height from the dimple bottom at the outer side surface are equal, the second rib is formed such that the height from the dimple bottom at the inner side surface is greater than the height from the dimple bottom at the outer side surface, and the second rib is positioned radially inward from the maximum width point.
