Claim:
1. An arrangement for adding an auxiliary wheel comprised of a tire mounted on a wheel rim to an axle of a motor vehicle on which is installed an original equipment wheel comprised of a tire mounted on a wheel rim, said auxiliary wheel rim being of the same configuration as said original equipment wheel comprising: a series of three generally cylindrical spacers attached together in end-to-end axial abutment with each other, including an inner spacer adjacent said original equipment wheel rim and having an annularly arranged series of holes, each receiving one of a set of stud bolts carried by an existing wheel brake assembly member of said vehicle, said inner spacer having an outer reduced diameter portion forming a shoulder receiving a rim of said original equipment wheel of said vehicle thereon, said inner spacer holes each counterbored to accept one of a set of stud nuts each threaded onto a respective stud bolt which are advanced on said stud bolts to draw an axially inside end closest to said brake assembly member of said inner spacer into abutment with said original equipment wheel rim and said wheel rim against said wheel brake assembly member; an intermediate spacer having an axially inside end abutting an axially outside end of said inner spacer located axially away from said brake assembly member, with an annularly arranged set of bolts each passing through a respective one of a set of counterbored holes extending axially completely through said intermediate spacer and threaded into a respective one of a set of threaded holes extending in from said axially outside end of said inner spacer to fixedly hold said intermediate and inner spacers together axially abutted end to end by said bolts; an outer spacer having an axially inside end abutting an axially outside end of said intermediate spacer with a set of annularly arranged counterbored holes extending through said outer spacer aligned with a set of threaded holes extending into said axially outside end of said intermediate spacer and a set of bolts each of which being installed in a respective one of said counterbored holes and advanced into a respective one of said set of threaded holes to hold said axially abutting ends of said outer spacer and intermediate spacer in abutment with each other; a set of counterbored holes extending axially into said axially inside end of said outer spacer aligned with a set of holes formed in said rim of said auxiliary wheel, a set of stud bolts inserted into said counterbored holes and through said rim holes, with a set of stud nuts each installed on a respective one of said stud bolts so as to draw said auxiliary wheel rim against an outer end of said outer spacer, whereby said inner, intermediate and outer spacers are fixed together in end-to-end abutment and with said inner spacer fixed to said brake assembly member of said vehicle.
