Abstract
Apparatus for curing a tire having an internal cavity using as heat and fluid pressure media first steam and then cooler inert gas. The time rate of pressure loss in the cavity is determined in each tire curing cycle by closing the cavity so as to form a completely closed chamber for a test time less than the normal cure time for the tire. Pressure loss during the test time is monitored and if determined to be at a greater than tolerable rate a warning device is actuated and means for loading a next tire into the mold is rendered inactive.
