Wheel for a vehicle includes a wheel rim, a tire mounted on the wheel rim to define an inflatable interior compartment, a pump for pumping air into the compartment, and an energy generating system for generating energy upon rotation of the wheel to power the pump and cause the pump to pump air into the compartment. The energy generating system may include a first coil, a magnetized mass movable upon rotation of the wheel relative to and partly in a chamber surrounded by the first coil, and an energy storage or load device coupled to the first coil. Upon rotation of the wheel, the mass moves relative to the first coil imparting a charge to the first coil which is stored in the energy storage or load device and used to power the pump when needed.
