Abstract
Apparatus for detecting leaks in pneumatic tires includes a source of pressurized carbon dioxide gas that is used to partially re-inflate the flat tire, so that a strong concentration of carbon dioxide gas will be present in any gas that leaks out of the tire. In the vicinity of the leak, the concentration of carbon dioxide gas is greatly enhanced above the normal atmospheric concentration of 300 to 800 parts per million. The enhanced concentration of carbon dioxide gas in the vicinity of the leak is detected by a gas sampling system that includes an audible alarm that alerts the user when the location of the leak has been found.
