A wheel assembly for a vehicle, includes a wheel rim ( 16 ) and a tire ( 18 ) defining a closed space ( 30 ) therebetween which is filled with a pressurized gas. The inventive wheel assembly also includes a pressurized-gas reservoir ( 40 ) and elements ( 50 ) for selectively connecting the pressurized-gas reservoir ( 40 ) to the closed space ( 30 ) defined between the wheel rim ( 16 ) and the tire ( 18 ). The pressurized-gas reservoir ( 40 ) is rotationally fixed to the wheel rim ( 16 ).
