A streamlined tailfin pivotably attached to a shaft-shaped member disposed on a vehicle provides for reduced drag in winds varying in direction impinging thereon.

A wheel assembly includes a wheel having a surface and defining a plurality of slots and a cap having a cap surface. The cap includes a plurality of positioning posts extending from the cap surface, each positioning post including a pillar and a stop fixed to the pillar. The pillar extends farther from the cap surface than the stop. The stop has a distal end. Each pillar is received by one of the slots of the wheel and the distal end of each stop is engaged with the surface of the wheel.

A wheel guard includes a cover having a cone shape with an outer surface, an inner surface, a top end, a bottom rim, a first terminal edge running from the top end to the bottom rim, and a second terminal edge opposite the first terminal edge and running from the top end to the bottom rim. A coupler is configured to releasably couple the first terminal edge to a plurality of different radial points of the cover, thereby adjusting a diameter of the bottom rim.

A magnetic hub plug apparatus for sealing a wheel hub and detecting wheel bearing failure includes a plug body having a plug outer side, a plug inner side, and a plug edge. A seal ring has a proximal perimeter coupled to the plug inner side, a distal perimeter, and a seal sidewall extending from the proximal perimeter to the distal perimeter. The seal ring is configured to sealingly fit within a wheel hub cap. A magnet extension is coupled to the seal ring. The magnet extension extends from the seal sidewall and dips within an oil reservoir of the wheel hub cap with each rotation. A magnet insert is coupled within the magnet extension to collect particles from a faulty wheel bearing. A plug grip is coupled to the plug body and extends from the plug outer side.

A wheel having a hub portion disposed in a center of the wheel, a center bore disposed at the center of the wheel and disposed within a perimeter of the hub portion, a center bore perimeter wall disposed around a perimeter of the center bore and a center bore profile nested within the center bore perimeter wall, the center bore profile having a snap cap engaging element configured to secure a snap cap and a CR adapter thread configured to engage with a lower thread of a CR adapter, and a CR adapter configured to attach a hex cap to the CR adapter thread. A lug cover may also be secured to the hex cap. The center bore profile allows for the selective utilization of either an ESR snap cap or a hex cap as part of a wheel, based upon application needs or aesthetic preference.

An illumination system for a vehicle wheel. A lighting component is attached to a hubcap, a wheel center hubcap, or both. The lighting component may be externally attached or embedded, or attached to a back side of the hubcap, the wheel center hubcap, or both. The lighting component may be a plurality of LED lights configured to illuminate an area external to the hubcap or wheel center hubcap. The lighting component may emit a single color or multiple colors of light either continuously or in a pattern. The lighting component is solar powered and may employ a battery backup. The illumination system may be controlled via a switch or wirelessly with an external controller or via a mobile application.

An aerodynamically optimized drag-reduction means and method for optimal minimization of the drag-induced resistive forces upon a terrestrial vehicle wheel, where the drag-induced resistive moments on wheel surfaces pivoting about the 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 means includes: a streamlined wheel cover positioned on a vehicle to shield the faster moving upper wheel surfaces from headwinds; a streamlined wind-deflecting fairing 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 arranged in one or more rows for greater axial strength; a streamlined tailfin rotatably attached to a wheel spoke, which thereby may pivot about the spoke in response to varying crosswinds; and a tire having streamlined tread blocks arranged in an aerodynamic pattern.
