Furthermore, one of the sidewalls at least partially covers and contacts the axially outer surface of the axially outer edge portion of the tread.

Provided is a tire having excellent rolling resistance and improved pass-by noise performance. The tire is a pneumatic tire comprising a side rubber provided on an outer side of a carcass in a tire width direction, in a sidewall portion, wherein a thickness of the side rubber in the tire width direction at a tire maximum width position is 1 mm or more, and a ratio 0° C. tan δ/30° C. tan δ of 0° C. tan δ to 30° C. tan δ of the side rubber is 2.00 or more, where the 0° C. tan δ is tan δ at 10 Hz and 0° C., and the 30° C. tan δ is tan δ at 10 Hz and 30° C.

A pneumatic tire having a tordial tire framework member having bead portions, sidewall portions and an under tread portion, and a ground contacting tread component disposed radially outside the under tread portion. The ground contacting tread component is made of a first resin material. The sidewall portions and the under tread portion are made of a second resin material. The bead portions are made of a third resin material. The tensile elastic moduli E1 to E3 of the first to third resin materials M3, respectively, satisfy E1<E2<E3.

Provided is a pneumatic tire including, on an outer surface of its sidewall portion, a decorative portion including a print layer and a protective layer located on a tire outer side of the print layer. The decorative portion further includes an intermediate layer located between the print layer and the protective layer. When a storage modulus of the print layer, a storage modulus of the protective layer, and a storage modulus of the intermediate layer are respectively defined as E1′, E2′, and E3′, the following relational expression is satisfied: E2′>E3′>E1′.

A pneumatic tire comprises: a tread portion; a pair of sidewall portions; a pair of bead portions each with a bead core embedded therein; a toroidal carcass extending between the bead portions; and a sidewall rubber disposed axially outside the carcass in each of the sidewall portions. The bead portion has a bead bottom surface which contacts with a bead seat of a wheel rim when the tire is mounted thereon. The bead bottom surface comprises an axially inner region including a bead toe and an axially outer region including a bead heel. The axially inner region is formed by a canvas chafer. The axially outer region is formed by the sidewall rubber extended radially inwardly from the sidewall portion.

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. When storage moduli at 80° C. of the print, inner, and outer layers are respectively defined as E1.sub.80′, E2.sub.80′, and E3.sub.80′, and storage modulus variations α1, α2, and α3 at high temperature of the print, inner, and outer layers are respectively defined as α1=|E1.sub.25′−E1.sub.80′|/E1.sub.25′, α2=|E2.sub.25′−E2.sub.80′|/E2.sub.25′, and α3=|E3.sub.25′−E3.sub.80′|/E3.sub.25′, α1<α2 and α1<α3, and E2.sub.25′>E2.sub.80′ and E3.sub.25′>E3.sub.80′ are satisfied.

In a tire 2, load support layers 20 extend, in portions inward of a carcass 10, from portions inward of beads 8, respectively, in the axial direction to portions inward of a tread in the radial direction. When a reference point P represents a point, on an outer surface of the tire 2, which is distant from a bead base line by 25 mm in the radial direction, a distance D1, at the reference point P, from the outer surface of the tire 2 to an outer side surface of a main portion 36 of a carcass ply 34 is greater than or equal to 3 mm and not greater than 10 mm.

In a tire 2 of the present invention, sidewalls 6 each include an outer layer 6a, and an inner layer 6b disposed inward of the outer layer 6a in the axial direction. The inner side end, in the radial direction, of the inner layer 6a extends to a region between a bead 10 and a chafer 8. When Po represents a contact point, on an outer surface of the tire 2, at which the outer layer 6a and the chafer 8 contact with each other, an inner side end, in the radial direction, of the outer layer 6a is equal to the contact point Po. In the radial direction, an outer side end 44 of the chafer 8 is disposed outward of the contact point Po. In the radial direction, an inner side end 46 of the inner layer 6b is disposed inward of the contact point Po.

In a tire 2 of the present invention, sidewalls 6 each include an outer layer 6a, and an inner layer 6b disposed inward of the outer layer 6a in the axial direction. A loss tangent of the inner layer 6b is less than a loss tangent of the outer layer 6a. When Hr represents a height, in the radial direction, from a bead base line BBL to an outer side end of a rim R, and Hi represents a height, in the radial direction, from the bead base line BBL to an inner side end 46 of the inner layer 6b, a ratio (Hi/Hr) of the height Hi to the height Hr is greater than or equal to 0.0 and not greater than 3.0.

A heavy-duty pneumatic tire includes a section width being equal to or less than 335 mm, an aspect ratio being equal to or less than 55%, and a toroidal carcass extending between axially spaced bead portions through a tread portion and sidewall portions. The carcass includes a carcass ply which includes a main portion and a turn-up portion turned up around a bead core of each bead portion. A belt layer is disposed radially outward of the carcass in the tread portion, wherein a radially outer end of the turn-up portion is located between the main portion and the belt layer in the tread portion. A sheeted rubber layer is disposed between the main portion and the turn-up portions in each sidewall portion.
