A pneumatic tire includes a pair of bead portions that are arranged at intervals wider than a regular rim width in a non-rim-assembled state. The bead portion includes a rim protector, a bead base, a bead heel, and a bead back surface. In the non-rim-assembled state, the bead back surface is formed with a recess that is recessed inward in the tire width direction. The bead back surface has a second curved portion constituting a deepest portion of the recess and a third curved portion extending inward in the tire width direction from the rim protector. When a height of the deepest portion is H2, a height H8 of a virtual intersection of a curve obtained by extending the second curved portion and a curve obtained by extending the third curved portion is larger than 1.5 times H10 and smaller than 3.0 times H10.

A pneumatic tire assembly includes: a tread portion including one or more traction features; a first sidewall portion coupled to the tread portion; and a first bead portion coupled to the first sidewall portion; wherein the first sidewall portion includes first bead traction features positioned proximate the first bead portion.

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 the plurality of protrusion portions including a radially outer protrusion portion with at least the intermediate portion disposed outward of a tire maximum width position in the tire radial direction, and a radially inner protrusion portion with at least the intermediate portion disposed inward of the tire maximum width position in the tire radial direction.

In a pneumatic tire mountable on a 5°-tapered rim, a bottom of a bead core is inclined from 0°-5° in a direction in which the bottom diverges toward an outer side in a radial direction as the bottom extends from an inner side in the width direction toward an outer side in the width direction. Each bead portion includes a base, a toe, and a heel. The base is inclined from 8°-12° in a direction in which the bead base portion diverges toward the outer side in the radial direction as the base extends from the inner side toward the outer side in the width direction. The heel has a radius of curvature from 25-30 mm. A rim cushion rubber has a modulus at 100% elongation within a range from 5.0-8.0 MPa. The toe has a displacement between before and after mounting on the rim from 9.0-13.5 mm.

A tire having a radial carcass reinforcement, made up of a single layer of reinforcing elements anchored in each of the beads by being turned up around a bead wire, reinforced by a stiffener. In the sidewall of the tire, the profile of the outer surface of the tire is at a constant distance from the carcass reinforcement layer between the points F and A, and meets the outer surface of the bead at the point C, forming two successive circular arcs.
