Adapter providing the connection between one tire bead and the rim. An axially inner end of the adapter is mounted on the rim seat, an axially outer end is mounted on the rim seat, a body connects said outer end to said inner end, a substantially cylindrical adapter seat receives one of said beads, and an adapter bearing face is substantially contained in a plane perpendicular to the axis. The reinforcer element of the axially outer end is entirely situated axially outside the bearing face. The body comprises, opposite the adapter seat, an annular seat protuberance, said protuberance comprising at least one rubber composition.

A multi-piece rim structure for a wheel includes a rim base 10, a bead seat ring 20 (ring member) and a lock ring 30. The bead seat ring 20 receives a load in a radial direction and an axial direction from a bead portion of a tire. An annular ridge 35 of the lock ring 30 can be received in an annular lock ring groove 15 of the rim base 10. A receiving groove 15a is formed in an inner surface of the lock ring groove 15 of the rim base 10. A sacrificial anticorrosion material 80 is embedded in the receiving groove 15a. The sacrificial anticorrosion material 80 includes metal such as zinc and aluminum that has a greater ionization tendency than iron that is a base material of the rim base 10 and the lock ring 30. Corrosion of the rim base 10 and the lock ring 30 can be suppressed by ionization of the sacrificial anticorrosion material 80.

A bicycle wheel rim made at least partially of a stratified composite material comprising structural fibers incorporated in a polymeric matrix. At least one opening, which passes through at least one first layer of composite material, is provided and at least one spoke attachment hole, which passes through at least one second layer of composite material, is also provided. The spoke attachment hole is completely contained within the opening in the first layer. A related manufacturing process is also described.

A vehicle wheel rim having at least an inboard tire bead seat retaining flange, an inboard tire bead seat, a well and an outboard tire bead seat. A reinforcing tape applied to at least a portion of one of an inner surface and/or an outer surface of the inboard tire bead seat retaining flange, the inboard tire bead seat, the well and the outboard tire bead seat.

A wheel rim for a vehicle including a first rim portion including a first wheel flange, a second rim portion threadedly connected to the first rim portion, and a second wheel flange held on the first rim portion.

A wheel rim for a vehicle including a first rim portion including a first wheel flange, a second rim portion threadedly connected to the first rim portion, and a second wheel flange held on the first rim portion.

A vehicle wheel, includes: a rim part at which a tire is mounted; a hub part disposed at an inner side of the rim part, attached to an axle hub, and coupled to a disc rotor of a disc brake; and a side connection part configured to connect a vehicle outer side part of the rim part with the hub part, in which: in an axle direction view, between the rim part and the hub part, plural through holes penetrating in the axle direction are formed aligned in a circumferential direction, and plural fins are formed at an inner peripheral surface of the rim part in series in a row in a circumferential direction thereof, each of the fins being configured at an incline from an outer side to an inner side in the wheel axis direction toward one side in the circumferential direction of the rim part.

Air valve for a pneumatic tire has a threaded shaft between a first end defining an air inlet and an opposite, second end that is located within the bounded space of a tire mounted on a rim. The air passageway through the air valve has at least one outlet at the distal end of the valve that exists the device through a side portion rather than the terminal end of the device. In a preferred embodiment the air passageway is T-shaped so that air flowing into the tire flows in a non-linear path, exiting the air outlets transverse to the air flow through the inlet into the air passageway.
