A run-flat tire has: a pair of bead cores; a carcass that straddles the pair of bead cores, and having end portions that are anchored on the bead cores; bead fillers that are made of resin and that extend from the bead cores along an outer surface of the carcass toward an outer side in a tire radial direction; and side reinforcing rubbers that are provided at tire side portions, and that extend in a tire radial direction along an inner surface of the carcass.

Provided is bead fiber with which sufficient air volume can be infused for making a high-performance bicycle tire, which has superior workability that does not require drying of the bead fibers when covering the bead fibers with rubber, and which is effective in preventing rim detachment. A high-performance bicycle tire can be obtained by using this tire bead fiber. The tire bead fiber is characterized by being formed using wholly aromatic polyester fiber with a modulus of elasticity of 800 cN/dt or greater.

A tire for a motor vehicle having at least one carcass ply comprised of a crown portion and two axially opposite side portions terminating in beads for mounting the tire on a rim. A tread band and a belt structure are interposed between the carcass structure and the bead. Each bead includes on elongated cord comprised of a first yarn, such as aramid, having a melting or decomposition point T.sub.1, and a second yarn, such as nylon, having a melting point T.sub.2, wherein T.sub.1>T.sub.2, and T.sub.2 is greater than 40 C.

Provided are: a cable bead which can realize a weight reduction while maintaining the breaking pressure resistance; and an airplane tire including the same. A cable bead (10) includes: a core (1) composed of an annularly formed steel; and a sheath (3) composed of at least one sheath layer, which is formed by spirally winding a sheath filament (2) composed of a steel around the core (1). The sheath filament (2) has a carbon content of higher than 0.90% by mass but 0.95% by mass or less, and a chromium content of 0.15 to 0.30% by mass.

A heavy load tire includes a bead core formed by a bead wire wound plural times in a ring shape, and a rubber sheet formed of a rubber material. The rubber sheet is wound on a region including one end portion and another end portion of the bead wire. The one end portion is served as an end portion closest to another end portion in a tire circumferential direction.

A pneumatic tire is provided that can achieve performance that is equivalent to or higher than that of known tires while allowing weight reduction of bead cores by using, for the bead cores, a composite cord. A pneumatic tire includes annular bead cores (5) embedded in bead portions (3), and a carcass layer (4) locked on the bead cores (5). Each of the bead cores (5) includes a cable bead structure in which a composite cord (10) is spirally wound around an annular core body (20), the composite cord including a core wire (11) formed of carbon fibers and a plurality of siding wires (12) formed of glass fibers disposed around the core wire (11).

The bead portion of the tire has an inner bead provided inside the tire width direction of a carcass ply and an outer bead provided outside the tire width direction of the carcass ply. The inner bead and the outer bead have a bead core portion including a bead cord formed of a metal material, and a filler portion provided outside the tire radial direction of the bead core portion and formed of a resin material. The inner bead and the outer bead sandwich a carcass ply.

A vehicle tire comprises a first casing layer spanning between and wrapping around first and second bead cores. The first casing layer has first edge sections that do not overlap with each other and stop short of a central tread region of the tire. A second casing layer has second edge sections that overlap the first edge sections of the first casing layer, and the second casing layer spans the central tread region. A tread layer spans the central tread region. A breaker belt is positioned in the central tread region between the second casing layer and the tread layer or between the first casing layer and the second casing layer. First and second sidewall regions are defined between the tread layer and the first and second bead cores, respectively. The sidewall regions comprise three plies of casing layers and the central tread region comprises two plies of casing layers.

An adapter for a rolling assembly having an axis of rotation (YY) comprises an axially inner end connected to a rim, an axially outer end comprising an outer reinforcing element and intended to come into contact, via a substantially radial axially inner face, or bearing face, with a bead, a body connecting the axially outer end to the axially inner end so as to form a single piece, comprising at least one main reinforcement providing the connection between the outer reinforcing element and the inner reinforcing element, and comprising a substantially axial adapter seat intended to come into contact with a bead. The outer reinforcing element (15) is completely axially on the outside of the bearing face (21), and the outer reinforcing element (15) is a substantially annular structure, referred to as a bead wire, of substantially polygonal section, comprising at least two first layers of composite and/or metallic material, and at least two second layers of rubber compound, the said first and second layers being arranged mutually parallel and in alternation with each other and parallel to the axis YY.

A pneumatic tire may include: a carcass; a belt reinforcing structure comprising a plurality of belt layers that include at least one spiral belt layer and at least one zigzag belt layer; and a tread comprising two or more main grooves extending circumferentially continuously around the pneumatic tire and defining a plurality of ribs that include two axially outermost ribs. At 10% to 100% of rated pressure and no load, each of the two axially outermost ribs may be raised (e.g., by a gap of 1 mm to 7 mm) in relation to a respective next nearest rib located axially inward of the respective axially outermost rib.
