Disclosed is an aluminum wheel for a vehicle, in which a resonance tube is coupled to a rim of the wheel, wherein a first surface of the resonance tube is fitted into a well groove formed in a well of the rim, and a second surface of the resonance tube comes into contact with the rim by a pressure member including a steel wire and a fixing member.

Provided is a vehicle wheel with a sub-air chamber member as a Helmholtz resonator attached to a rim. The sub-air chamber member includes a main body having a sub-air chamber therein, a tubular body providing communication between the sub-air chamber and a tire air chamber, and a cover member covering the main body. The main body is disposed on a rim inner circumferential surface portion of the rim present on an inner side of the rim in a wheel radial direction and extending in a wheel width direction. The tubular body is disposed in a through-hole provided in the rim so as to provide communication between the inner side of the rim in the wheel radial direction and the tire air chamber side. The cover member covers the main body from an inner side in the wheel radial direction.

An expanding tire rim comprises an inner hub in hydraulic communication with a plurality of arms having curved outer rim sections. When activated by a user the hydraulic system permits the diameter of the outer rim to expand. Each arm has a plurality of tire retaining spikes.

A rim for a tire for means of displacement preferably for heavy loads at low-speed. The rim may include a main tubular body having a cylindrical surface extending between two lateral edges, a bead-seat having a greater diameter than the cylindrical surface of the tubular body and overlapped to it and at least a side-ring being overlapped to one of the lateral edges for the lateral containment of the tire. The rim may include compensating means interposed between the cylindrical surface of the tubular body and the bead-seat and in contact with them to realise a compensation in thickness.

A two-piece wheel may have a first section and a second section. The wheel has areas of varying diameter across its width, and the first section and second section are joined at the area of the wheel with the smallest diameter. The first section can be a spoke section with spokes extending from a central hub and the second section can be a barrel section.

A tire and wheel system having a core and an over-injected tire in the core, and a method of manufacturing a wheel and tire assembly. The tire and core assembly is coupled to the wheel by the engagement of an indentation of the core in a recess of the wheel. When used in a wheelchair, a plastic or metal thrust ring is coupled on the wheel by pins and screws in order to make it possible to transfer movement to the wheel.

A bicycle component comprises a first structural member made of a conducting material, an electrical insulation layer provided to the first structural member, and a second structural member configured to be attached to the electrical insulation layer by adhesive.
