     DETAILED DESCRIPTION of INVENTION  
     [0006] Simple Spare  
     [0007] The Simple Spare was developed in order to greatly facilitate the changing of the spare tire on any vehicle that carries its spare tire underneath it. With just a touch of a button located on the instrument panel, rear cargo area or keyless remote, one can lower and raise the spare tire without having to go through the usual painstaking process we&#39;ve always been forced to endure . . . until now! 
     [0008] How it Works  
     [0009] The Simple Spare is just that. Simple! The compact motorized unit is mounted right next to the existing spare tire winch. We&#39;ve developed a unique clutch assembly that goes between the winch and the Simple Spare unit. This clutch prevents the user from accidentally burning out the motor should he/she keep the power button depressed in the ‘reverse’ or ‘up’ position. As the size of the tire changes, so does the size of the clutch as well as the gauge of the wire sending power to the motor. The clutch assembly also serves a second purpose. Should the motor ever fail to operate, the user can still operate the winch using the conventional ‘hand crank’ method. The motor has sufficient torque, is weather proof and requires no maintenance,  
     [0010] The Simple Spare is a safety conscious system. It will only operate when the vehicle is in the ‘PARK’ position on an automatic transmission or when the emergency brake is applied on a vehicle with a manual transmission. The good news is that the operator of the vehicle may choose to leave it running (with the A/C on) during use of the Simple Spare in case there are any ‘perishables’ inside that need to be kept cool.  
     [0011] The Simple Spare substantial reduces the amount of time you would normally take to lower and raise your spare, but more importantly it reduces your overall exposure time to traffic. It shouldn&#39;t take a lifetime to change a tire and with the Simple Spare it won&#39;t.
