An inflator disposed within a tubeless tire for inflating the tubeless tire. A rechargeable electric storage disposed within a tubeless for providing electricity. An electric air compressor is mounted on an inside surface of the rim of the tubeless tire within the pressure cavity of the tubeless tire. The electric air compressor and an air pressure sensor disposed within the tubeless tire runs by a controller. The electric air compressor has a compressed air inlet vented to atmosphere in a custom valve stem through a conventional hole of a valve stem in the rim of the tubeless tire. A motion activated power generator recharges the rechargeable electric storage. A short-range radio transmits measured pressure data for each tire to a central OBD module plugged into in the vehicle. The central OBD module connects through a smartphone indirectly or directly to a central server via a networked cellular radio tower.
