Add-on spare tire apparatus and method of installation

A spare wheel for use on a vehicle having a disabled tire without removing a wheel carrying said disabled tire, comprising:

• a first wheel half, said first wheel half having an outer periphery, an attachment plate, a plurality of mating plates;
• each said mating plate of said first wheel half having a keyhole aperture and a wheel lock pin aperture, said keyhole aperture having a large opening portion and a small opening portion;
• said attachment plate having a plurality of pins extending therefrom and a plurality of reinforced apertures;
• said wheel carrying said disabled tire having a plurality of keyhole apertures and a plurality of plate lock pin apertures, said keyhole apertures having a large opening portion and a small opening portion;
• a plurality of plate lock pins;
• whereby said attachment plate is attached to said wheel carrying said disabled tire by insertion of said pins extending from said attachment plate into said large opening portions of said keyhole apertures in said wheel carrying said disabled tire and rotating said attachment plate so that said pins are held by said small opening portions and said attachment plate is secured to said wheel carrying said disabled tire by coupling said reinforced apertures of said attachment plate to said plate lock pin apertures through said plate lock pins;
• a second wheel half, said second wheel having an outer periphery, a plurality of mating plates;
• each said mating plate having a reinforced aperture and a pin extending therefrom;
• a plurality of wheel lock pins;
• whereby said second wheel half is attached to said first wheel half by insertion of said pins extending from said mating plates of said second wheel half into said large opening portions of said keyhole apertures in said mating plates of said first wheel half and shifting said second wheel half so that said pins are held by said small opening portions and said second wheel half is secured to said first wheel half by coupling said reinforced apertures of said mating plates of said second wheel half to said wheel lock pin apertures through said wheel lock pins;
• and
• tread disposed on said outer peripheries of said wheel halves.

A method for mounting a spare wheel on a vehicle having a disabled tire without removing a wheel carrying said disabled tire, comprising:

• providing a first wheel half, said first wheel half having an attachment plate, the attachment plate defining a plurality of pins extending therefrom;
• mounting said attachment plate to said wheel carrying said disabled tire by inserting said pins into keyhole apertures in said wheel carrying said disabled tire;
• rotating said attachment plate until said pins are held by said keyhole apertures;
• rotating said first wheel half until said first wheel half engages the ground;
• and
• attaching a second wheel half to said first wheel half.
