Title: Tyres, deflation warning
IPC: B60B21/12
Filed: 1972-12-12
Abstract: A pneumatic tyre and wheel assembly comprises an enclosing means for a lubricating material which releases the lubricating material into the tyre when the tyre becomes deflated. A counterbalancing mass counterbalances the mass of the enclosing means and the lubricating material so that when the lubricating material is released the assembly becomes out-of-balance. The enclosure is a breakable diaphragm ruptured by collapse of the tyre onto the tim upon deflation. Alternatively a pressure sensitive valve may release the material. The enclosures is carried by the well of the rim.
