ABSTRACT:
A vehicle wheel assembly includes a tire, a rim, an air valve and a relief valve. The relief valve can be installed in the rim, in the tire, or incorporated into the housing of the air valve to communicate directly with the interior of the tire; or as an adapter attachable to the outer end of the air valve. The relief valve includes an aperture normally covered by pre-stressed flexible belt which seals the aperture, but upon the presence of excessive pressure in the tire is deforming to vent the excessive pressure to the atmosphere. A second described variation relief valve includes a weakened portion of its housing which is automatically ruptured upon the presence of excessive pressure; this variation provides a one-time venting adapter.
