Abstract
The present invention couples a tire pump with the wheel rim of a vehicle. The pump is activated electromagnetically to inflate the tire as desired, e.g. when tire pressure is below a required value. The pump is arranged to draw air from the atmosphere and pump into an interior portion of the tire. A magnetized plunger within the pump is biased to an initial position by a biasing element. Energizing an electromagnet generates a magnetic field. The pump is arranged to rotate in and out of the magnetic field to cause the plunger to reciprocate and inflate the tire.
