<p>Inside a tight sealed chamber (2) defined between a rim (15) and a tire (1) 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 (4) 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 (1).</p> |
