ABSTRACT:
An apparatus including a body tube coaxially mounting an internally threaded lower cylindrical skirt at a lower terminal end thereof for securement to a valve member of a conventional automotive tire. An apertured cylindrical web is mounted adjacent an intersection of the tube and cylindrical skirt, including an axial rod fixedly mounted projecting coaxially of the skirt for projection and depressing of a central displacement needle seat, as utilized in automotive valves. A flexible web formed of memory retentent material is mounted adjacent an upper terminal end of the tube below a translucent viewing lens. The web includes a rigid boss member mounted thereon, whereupon proper inflation within an associated tire permits projection of the boss against the translucent lens for viewing of the boss' indica of proper inflation, whereupon deflation permitting the web to deflect and displace the boss relative to the lens provides visual indication of underinflated condition.
