A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

An aerodynamically optimized drag-reduction appartus and method for optimal minimization of the drag-induced resistive forces upon a terrestrial vehicle, where the drag-induced resistive moments on wheel surfaces pivoting about the stationary point of ground contact are reduced, and the vehicle propulsive forces needed to countervail the resistive forces on the wheel are reduced. The drag reduction apparatus includes: a streamlined fairing or wind deflector positioned on a vehicle to shield the faster moving upper wheel surfaces from headwinds; an engine exhaust pipe disposed on a vehicle whereby exhaust gases deflect headwinds to shield the faster moving upper wheel surfaces of an automotive wheel; an automotive spoked wheel having streamlined oval-shaped wheel spokes; a wheel assembly with a streamlined tailfin rotatably attached to a wheel spoke; a wheel with a tapered spoke having a thin aerodynamic profile near the rim and tapering to a round profile toward the central hub; and a tire having streamlined tread blocks arranged in an aerodynamic pattern.

A two-piece rim and tire assembly. The tire is held to the rim by fasteners extending through flanges integral with the tire main body and then into the rim. Further, the outer edges of the rim clinchably mount the tire main body thereto. A flexible overhanging portion extends outwardly of the tire main body minimizing dirt and mud accumulation on the tire and rim. A bearing is held within the rim by a ring.

The invention relates generally to the field of vehicle rims, and more specifically to Logo Rims or Dual Logo Rims. The invention also relates to a vehicle Dual or Logo Rim apparatus, and a method of making same. More particularly, the invention encompasses a customized tire rim for a vehicle. The invention also provides a user to replace their existing tire rims with the inventive customized vehicle rim having, and using a customized or a personalized logo. A line of specially designed tire rims that are adorned with a variety of striking designs, sporting logos germane to sports, businesses, and popular culture, is also disclosed. The invention also provides an inventive design which is intended to provide automobile enthusiasts with an attractive alternative to ordinary tire rims. The inventive rims can be a single unit rim or two separate rims that are joined to form a single tire rim.

A wheel assembly includes a split wheel, a nut, and bolt. The split wheel comprises a first wheel portion and a second wheel portion, and the nut comprises a first portion and a second portion. The first portion of the nut comprises a thrust face engaging the split wheel, the nut defines a bore extending through both the first portion and the second portion, the bore in the first portion is nonthreaded, and the bore in the second portion is threaded. Further, the bolt extends through the first wheel portion and the second wheel portion, with a threaded end of the bolt extending through the first portion of the nut and being coupled to the second portion of the nut, according to various embodiments. The effective bending length of the bolt is greater than the clamped length of the bolt.
