## Background
The present invention relates to a vehicle wheel, spacers or separating means and tire carrying rims having radially inwardly projecting components thereon. The rims are dual mounted, inner and outer, on the wheel.

The vehicle wheel has a plurality of spaced-apart felloe portions for rim mounting and is preferably a spoked wheel. The spacers are non-compressible and comprise an individual element for each wheel felloe portion.

The prior art relating to vehicle wheels for carrying demountable rims and spacers or separating means therefor includes the patents to be found (the July, 1973, classification) in class 301, beginning with sub-class 10R. Generally relevant to the present invention are the patents relating to the mounting of plural or dual rims, inner and outer, normally found in sub-classes 13R and 13SM.

The accurate mounting of tire carrying rims on the felloe, felly or load bearing portion of a wheel has long been a problem in the art. Vehicle operators and industry regulations seek longer tire life and complete safety in operation, even under the most severe of vehicle operating conditions. The tire manufacturers are endeavoring to provide tires which have optimum performance characteristics, including lateral and radial balance. Consequently, it is being required that this art provide elements, the wheels, the rims, the fastening assemblies and the spacers, which do not deteriorate, hinder or impair the projected performance characteristics of the tires.

Heretofore, the wheel of a tire-rim-wheel assembly has been regarded primarily as a load carrying element attached to an axle of the vehicle and carrying the rim. The periphery of the wheel has felly surfaces to pilot or guide the rim into approximate mounting position. Thereafter, fastening means or assemblies are torqued down or tightened in such a manner that the tire carrying rim would not come loose from the wheel during use. If done correctly, as by an expert and conscientious mechanic, the prior art rim mounting techniques would not deteriorate, hinder or impair the performance characteristics of the tires. However, environmental or extrinsic factors such as warpage, deformation or damage to the rim and spacer or wear of the fastening means or assemblies could lead to relative displacement or non-alignment of the assembly components during fastening, creating conditions of what are now commonly referred to .[. as.].  excessive lateral (axial) or radial runout, or an imbalance of the tire-rim-spacer-wheel assembly during vehicle operation.

The inventors have determined that the concepts of vehicle wheel, spacers, tire carrying rims and fastening assemblies disclosed herein will permit of improved rim mounting techniques.

A wheel and spacers according to the invention, when used with rims and fastening assemblies adapted thereto, should reduce lateral (axial) and radial runout, resist rim warpage or deformation, restrict rim rotation relative to the wheel and spacers and provide better balance for the tire-rim-spacer-wheel assembly during vehicle operation.

The object of the present invention is to provide an improved vehicle wheel, spacers, tire carrying rims and fastening assemblies adapted thereto.

It is a further object of the invention to provide an improved vehicle wheel and spacers for dual mounting of tire carrying rims having radially inwardly projecting components thereon. The mounting of such rims is greatly improved by creating and maintaining an operative relationship between the wheel felloe surfaces for rim seating, the location and position of the rims and spacer, and the location and function of the axially projecting components of the fastening assemblies for locking the rims and the spacers on the wheel.

These and other objects of the invention, as well as the advantages thereof, will be apparant in view of the detailed description of the various embodiments thereof as set forth below.

In general, a wheel according to the invention has a plurality of spaced-apart felloe portions. Each wheel felloe portion has a generally concave and axially extending pocket thereon for housing an axially projecting component of a fastening assembly for locking the rims and a spacer on the wheel. The axially inner end of each pocket has or terminates at a radially directed surface providing a mounting location for an axially projecting component of a fastening assembly. The radially directed surface intersects a radially inclined felloe surface for seating an inner rim. The axially outer end of the wheel felloe pocket has axially directed wing portions providing for dual axially oriented surfaces for seating an outer rim.

In general, a spacer according to the invention is non-compressible and comprises an individual element for each wheel felloe portion with a bore for receiving the shank of an axially projecting component of a fastening assembly for locking the rims on the wheel. .Iadd.

In general, a tire carrying rim with radially inwardly projecting components thereon comprises a radially inclined axially inner surface tapering toward an adjacent radially inwardly directed portion oriented substantially perpendicular to the rotational axis of the rim and having a bore therein for receiving the axially projecting component of a fastening assembly. .Iaddend.

One form of tire carrying rim according to the invention has radially inwardly projecting components for doweled and tenoned engagement with a spacer carried by the axially projecting component of a fastening assembly.
