A vehicle wheel for the purpose of slow speed temporary movement of the vehicle whereby the inner portion of the wheel disc includes a curved surface disposed in rotating contact with the beveled surface of the cylinder element of the attachment hub. The wheel disc and the attached tire extend outwardly from the attachment hub. The attachment hub includes the cylinder with a securing ring affixed to the inwardly extending portion of the cylinder and disposed in abutting relation with the inner surface of the wheel disc wherein the outer surface of the cylinder is disposed between the securing ring and a flange.

Wheel hub adaptor (11) attachable to vehicle wheel to attach vehicle accessory for rotation with vehicle wheel, has an inner mounting plate (15) with recesses or apertures (17) to match a vehicle wheel stud pattern, a body (19) extending from the plate (15) to an outer mounting plate (27) having a mount to which the vehicle accessory attaches. The mount has apertures (65) which align with studs (75) on a mating mount of the vehicle accessory. The inner mounting plate and the outer mounting plate mount to the vehicle wheel and vehicle accessory respectively, by rotating apertures (17 65) to stop portions (35 71), and is secured by a bolt passing through one of two circular apertures (43 45) or (67 69). Vehicle accessories can be provided like a paddle to self-propel the vehicle in sand, and a wheel to widen the vehicle track.

An external runflat apparatus for a guide wheel system of a monorail transport system. The external runflat apparatus includes a hub member and a tread member. The tread member is connected to the hub member and includes a base member and a covering over the base member.

A system for attaching a plate to a vehicle is provided. The system includes lug nuts and lug bolts for attaching the plate to a threaded wheel stud. The lug nuts each define a threaded stud recess for engagement with a threaded wheel stud and a threaded bolt recess for engagement with a threaded portion of a lug bolt. The lug bolts each define a head for rotating the threaded portion of the lug bolt into the bolt recess of the lug nut, a shaft positioned between the threaded portion and the head, and a rotatable portion. The rotatable portion defines a center aperture freely rotatable about the shaft and a bolt aperture for accepting a fastener. A lock nut is positioned about each of the lug bolts for locking the lug bolt into position relative to the lug nut.

A system for compensating for a flat tire, including a tire deployment sub-system and a tire pressure monitoring sub-system. The tire deployment system comprises an extendable auxiliary tire mounted to the frame of the automobile that is in communication with the tire pressure monitoring system and a user interface. The tire pressure monitoring system is adapted to monitor the internal pressure of the tires of the vehicle, via either direct or indirect means, and send a notification signal to the tire deployment system when the pressure sensor detects that one of the tires of the vehicle is losing pressure. The deployed auxiliary tire provides a temporary support for the tire that has gone flat, allowing the driver to continue driving for a period of time and thereby obviating the need to immediately pull to the side of the road and change out the flat for a spare tire.

An attachment is provided for a vehicle wheel, having a rim and a tire arranged on the rim, for enabling a driving operation with a restricted tire function in an operating state in which the attachment is fastened on the vehicle wheel. The attachment may include a stationary section configured to be fastened immovably with respect to the rim in the operating state in which the attachment is fastened on the vehicle wheel, a tread section with a tread for contacting the road, and at least two clamping devices configured to engage behind a section of the rim to fasten the attachment on the vehicle wheel, wherein the tread includes at least one tread segment arranged movably in a circumferential direction with respect to the stationary section in the operating state in which the attachment is fastened on the vehicle wheel.
