ABSTRACT:
A method and apparatus for detecting deflection in a pneumatic tire (10) includes a light source which is transmitted by a transmission line (15,17) to a position internally of the tire (10). The light is reflected off an internal surface of the tire (10) and transmitted to an electronic circuit (25) by a second transmission line (19,21). An alarm (29) will alert the operator of the vehicle of undue tire deflection and, in addition, a visual display (31) can provide the operator with an instantaneous indication of tire deflection.
