    摘要： The pneumatic tire (1) comprises a pair of bead cores (11, 11), a pair of bead fillers (12, 12) disposed outward of the pair of bead cores (11, 11) in a tire radial direction, a carcass layer (13) disposed folded around the bead cores (11) and the bead fillers (12), and a steel chafer (21) including an arranged plurality of steel cords, the steel chafer being disposed between the carcass layer (13) and a rim engaging surface. A height Hs of an outer end portion (211) of the steel chafer (21) located outward of the bead fillers (12) in a tire width direction and a rim flange height Hf have the relationship: 0.5 ≤ Hs/Hf ≤ 1.0, where the height is measured from a measuring position of a rim diameter.

    摘要： A pneumatic tire includes a tread, sidewalls, clinches, beads, a carcass, and strips. Each bead includes a core, a first apex and a second apex; the carcass includes a carcass ply which is turned up around the core from the axially inner side toward the outer side, such that it is divided into a main and a turn-up portion; each strip has a radially inner edge positioned between the main and turn-up portions; the second apex is positioned between the turn-up portion and each clinch; each strip has an outer edge in the radial direction positioned to correspond to or on inner side of the point of the tire maximum width; the second apex has an outer edge which is radially inner than the outer edge of each strip, and includes crosslinked rubber having a complex elastic modulus in a range of from 60 to 70 MPa.

    摘要： In the present invention, a carcass (120) of a pneumatic tire (1A) comprises a toroidal-shaped carcass main body (121) and a carcass folded part (122) folded at a bead core (111). A bead filler (131) is disposed outward of the bead core (111) in the tire radial direction. A rubber sheet (132) is disposed outward of the bead filler (131) in the tire radial direction. A space (DA) is formed between the tire radial direction outer side end (131a) of the bead filler (131) and the tire radial direction inner side end (132b) of the rubber sheet (132).

    摘要： A tyre comprising two beads, each bead comprising an annular reinforcing structure, a carcass reinforcement, anchored in the two beads by a turn-up around the annular reinforcing structure, so as to form a main portion and a wrapped-around portion. Each bead comprises a bead filler situated at least partially between the main portion and the wrapped-around portion of the carcass reinforcement. Each bead further comprises an outer strip situated axially on the outside of the wrapped-around portion of the carcass reinforcement. The bead filler has a thickness E(r), this thickness corresponding to the length of the intersection of the direction perpendicular to the main portion of the carcass reinforcement with the bead filler, r denoting the distance separating the point of intersection of the direction perpendicular to the main portion of the carcass reinforcement with the carcass reinforcement from the radially innermost point of the annular reinforcing structure. The assembly formed by the bead filler and the outer strip has a thickness ET(r). For all the points of intersection of which the radial distance from the radially innermost point of the annular reinforcing structure is greater than or equal to 10% and less than or equal to 35% of the radial height H of the tyre, the ratio E(r)/ET(r) is greater than or equal to 0.3 and less than or equal to 0.5.

    摘要： In an apex 34 of a tire 2, a reinforcing portion 48 is located inward of a main body 46 in an axial direction. When a position on an outer surface of the tire 2 at which position a height from a BBL is 14 mm is defined as a first point P1 and a position on the outer surface of the tire 2 at which position a height from the BBL is 20 mm is defined as a second point P2, the reinforcing portion 48 overlaps the first point P1 and the second point P2 in a radial direction. A loss tangent of the reinforcing portion 48 is equal to a loss tangent of the main body 46 or less than the loss tangent. A hardness of the reinforcing portion 48 is equal to a hardness of the main body 46 or greater than the hardness.
