Why a belt strap for a machine

In another article I was saying that you can make a strap for motor from the flat part of the car tyre, the part that touches the floor, remembering you make the strips, and connect them with staples, the points are to be for the outside you can make of the size that you want, of course, the option to that is of thick leather, and the utility is if you are an inventor and make a machine that does a work like thresh corn, and you don't know how to do the motor of the machine but only the work part, you can make your invention be with a part that will be in the place of the crank will be replaced for any motor that you can recover from a car or motorcycle or boat, and connect it to the crank of your machine with a belt to the motor, this way a mechanical machine will turn for a motor and probably is easier of constructing a machine with a belt than one that you gonna make the electrical part.
