A wheel assembly for a tire includes a circular hub member for securing to a rotatable axle of a vehicle, a first rim piece for engaging the hub member, a second rim piece for engaging the first rim piece, and a plurality of cylindrical sleeves for engaging both the first rim piece and the second rim piece. The first rim piece has cylindrical first shafts each engaging a first end of one of the sleeves. The second rim piece has cylindrical second shafts each engaging a second opposite end of one of the sleeves. An outer cylindrical surface of each sleeve engages a separate and distinct part the tire.

A wheel hub assembly assembly having a central axis (X) and covers therefore. An outer ring provided with a tubular mounting portion, and a cover having a keying portion which is inserted inside the tubular mounting portion. The cover is made of plastic material, the keying portion comprises an annular seat made of plastic and a sealing element made of rubbery elastic material. The sealing element is defined by a solid of rotation mounted inside the annular seat over a whole of an axial length of the annular seat so as to project radially outside of the annular seat to make contact with the tubular mounting portion of the outer ring thereby sealingly closing the wheel hub assembly.

A tire/wheel assembly of the present disclosure includes a tire with a tread portion and a wheel with a rim. The tire is mounted on the rim, and the tire/wheel assembly includes a power reception coil. In the contact patch when the tire/wheel assembly is filled to a prescribed internal pressure and subjected to the maximum load, the rectangle ratio of the ground contact length at a position, in the tire width direction, located 10% of the ground contact width inward in the tread width direction from an edge in the tire width direction to the ground contact length at the center of the contact patch in the tire width direction is 50% or more.

A traction board for insertion under a vehicle's tire for freeing the vehicle from a stuck condition includes an elongated board body and an end plate pivotally connected to an end portion of the elongated board body. According to a further aspect, a traction board includes an elongated board body and a finger pivotally connected to the elongated board body and pivotally extending below the elongated board body in order to prevent the elongated board body from sliding rearward.

A non-pneumatic tire includes an inner ring, an outer ring, and a plurality of loops extending between the inner ring and the outer ring. The plurality of loops including at least a first loop and a second loop, wherein the first loop and the second loop are each in direct contact with both the inner ring and the outer ring. The first loop has a single reinforcement layer disposed therein, and includes a first extent that extends between the inner ring and the outer ring and a second extent that extends between the inner ring and the outer ring. The second loop has a single reinforcement layer disposed therein, and includes a third extent that extends between the inner ring and the outer ring and a fourth extent that extends between the inner ring and the outer ring. The second extent is in direct contact with the third extent.

A rim assembly for a bicycle wheel includes a rim, a first protruding tire retaining feature attached to a first surface of the rim, and a second protruding tire retaining feature attached to a second surface of the rim. The first surface is a surface of a first tire retaining wall of a radially outer tire engaging portion of the rim, and the second surface is a surface of a second tire retaining wall of the radially outer tire engaging portion. The second surface faces the first surface. The first protruding tire retaining feature and the second protruding tire retaining feature are made of a first material, and the first tire retaining wall and the second tire retaining wall are made of a second material. The second material is different than the first material.

A bicycle rim basically includes a first annular side surface portion, a second annular side surface portion, an annular connecting portion and an outermost layer. The first annular side surface portion includes a first braking surface. The second annular side surface portion includes a second braking surface. The epoxy resin layer is an example of a nonmetallic layer. The annular connecting portion connects the first and second annular side surface portions. The soft additive granules are disposed in at least one of the first and second annular side surface portions. The epoxy resin layer is disposed in at least one of the first and second annular side surface portions. The soft additive granules are at least partially embedded in the epoxy resin layer. The outermost layer covers the epoxy resin layer and the soft additive granules.

An aircraft wheel including a rim (2) comprising two assembled-together rim halves (3a, 3b), each rim half (3a, 3b) having a bearing surface (7) extending in a plane perpendicular to an axis of rotation (X) of the aircraft wheel. The aircraft wheel further includes a spacer (9) situated between the two bearing surfaces (7) when the rim halves (3a, 3b) are assembled together.

The present invention provides a hub cover for a wheel hub on a vehicle used for agriculture and a stud extension piece used to operatively affix the hub cover to the wheel hub. In a preferred embodiment, the hub cover comprises a polyethylene convex dome that is affixed to the wheel hub of the vehicle using a stud extension piece that couples the hub cover to an exposed wheel hub. The use of the hub cover minimizes crop damage caused by the exposed hubs of the vehicle in crop fields.

A bicycle component comprises a base member and a first alumite layer. The base member is made of an aluminum alloy. The first alumite layer is provided on the base member. The first alumite layer has a thickness that is equal to or larger than 1.0 μm.
