A pneumatic tire has a carcass layer, a side wall rubber which forms an outer surface of a side wall portion, and a rim strip rubber which forms an outer surface of a bead portion. The rim strip rubber extends in a tire radial direction between the carcass layer and the side wall rubber. A height of the rim strip rubber on the basis of an outer diameter position of a bead core buries in the bead portion is equal to or more than 70% of a height of a tire outer diameter position. A thickness Tw of the rim strip rubber at the tire maximum width position is smaller than the maximum thickness Tm of the rim strip rubber which is closer to an outer side in the tire radial direction than the tire maximum width position.

A pneumatic tire is configured by a resin tire frame member. An inner face of the tire frame member is provided with an attachment section. The attachment section is configured so as to attach a sound-absorbing material inside the tire frame member. The sound-absorbing material employs, for example, a spongey material, and the sound-absorbing material is capable of absorbing sound.

Provided is a pneumatic tire including, on an outer surface of its sidewall portion, a decorative portion including a print layer and inner and outer layers respectively disposed on tire inner and outer sides of the print layer. When storage moduli at 25 C. of the print, inner, and outer layers are respectively defined as E1.sub.25, E2.sub.25, and E3.sub.25, E1.sub.25<E2.sub.25 and E1.sub.25<E3.sub.25 are satisfied.

A radial tire (10) for a heavy vehicle of construction plant type, and more particularly, the sidewalls thereof (20), arranged to minimize the temperature of the tire while guaranteeing its electrical conductivity. The tread (30) comprises two tread wings (31) and a central portion (32). The bead layer (71), the elastomeric coating compound of the carcass layer (50), the second sidewall layer (22) and the tread wing (31) constitute a preferential conductive pathway of the electric charges between the rim and the ground when the tire is mounted on its rim and flattened on the ground.

A pneumatic includes a pair of sidewall portions. At least one of the sidewall portions is provided on an outer surface thereof with a first protruding portion arranged on an outer side in a tire radial direction and a second protruding portion arranged on a radially inner side. Both protruding portions are formed so as to be convex outward in a tire axial direction. The second protruding portion has a protruding apex surface formed of a different colored rubber material having a different color from an outer surface of the first protruding portion. A distance in the tire radial direction between an inner edge in the tire radial direction of the first protruding portion and an outer edge in the tire radial direction of the second protruding portion is 40% or more and 220% or less of a length in the tire radial direction of the second protruding portion.

Plural inner face grooves 40 are formed to tire inner faces of a tire frame member 17 formed from a resin material. The inner face grooves 40 are formed to a region from an inner separation point corresponding to a separation point of a bead portion 12 from a rim 20 as far as an inner end portion 30 IN corresponding to a tread end 30A of a tread member 30.

A vehicle pneumatic tire includes a tread, ply structure, and radial carcass extending around a bead core in each bead region and extending back under the ply structure. Side wall regions are formed by a wing rubber extending from the side of the tread toward the bead region and a rim protection rubber extending from the bead region toward the wing rubber. The wing rubber is the only rubber component extending to the tread and runs in the radially outer portion of the side wall region in contact with the carcass and covers the adjacent rubber component toward the bead region by the radially inner end section of the wing rubber. The adjacent rubber component includes an end section in the covered region narrowing toward the tread, the end of which is located a distance from a base line between 45% and 70% of the height determined therefrom.

A pneumatic tire includes: a bead core; a bead filler; a carcass ply; a side wall rubber that is arranged on the tire-outer-surface-side of the carcass ply and constitutes a tire outer surface; a chafer layer that is turned from the tire-inner-surface-side to the tire-outer-surface-side around the bead core and the bead filler and rolled up on an outer surface of the carcass ply; a pair of support rubbers that are located between the side wall rubber and the carcass ply and arranged so as to hold a rolled-up end of the chafer layer from both sides in a tire width direction; in which modulus values of the pair of support rubbers are higher than a modulus value of the side wall rubber, and hardness of the hardened support rubber is enhanced while scorch resistance of an unvulcanized rubber composition is maintained.

A pneumatic tire includes a pair of bead cores; a pair of bead fillers; a carcass ply; a side wall rubber; a chafer layer that is rolled up on an outer surface of the carcass ply; and a pair of support rubbers that is located between the side wall rubber and the carcass ply and arranged such that a rolled-up end of the chafer layer is sandwiched from both sides in a tire width direction. The pair of support rubbers includes a tape rubber located inside in the tire width direction and a rear pad rubber located outside in the tire width direction. A modulus value of the tape rubber is higher than a modulus value of the side wall rubber. A modulus value of the rear pad rubber is higher than the modulus value of the tape rubber.
