The main purpose of this paper is to generate electricity from the normal rolling motion of the tires. We are proposing a model of tire that consists of a circular pipe wound with copper coil on the outer surface of the pipe. An N-52 powerful magnet is placed which is free to move inside the pipe. Faraday’s law of electromagnetic induction states that when the magnetic flux linking a circuit changes, an electromotive force (emf) is induced in the circuit proportional to the rate of change of the flux linkage. If there is any change in relative motion of the tire and the magnet due to sudden speed changes an induced emf will be produced in the coil. The maximum voltage will be produced if the tire stops suddenly. As the magnet inside the circular pipe will keep on moving due to inertia. The emf generated is stored in a battery that can be used as a secondary source of energy for the vehicle.
