ABSTRACT:
Inside a tight sealed chamber defined between a rim and a tire of a pneumatic tire wheel for vehicles, there is provided a predetermined amount of a two-phase system in a substantially balanced state at the tire temperature and inflation pressure. The two-phase system comprises a liquid in a balanced state with its own vapor contained within a sealed, elastically deformable toric bladder which is mounted to the rim. By changing the amount of heat in the two-phase system so as to change its balance condition, a variation is obtained in the inflation pressure of the tire.
