ABSTRACT:
A method and apparatus (10) for determining the presence of bulges and valleys in the sidewall of a tire (12). Displacement transducers (16-20) monitor deflections in the sidewalls of the tire (12) and provide output signals characteristic of such deflections. A differentiator (38) determines the slope of such deflections and, for such periods that the output of the differentiator (38) exceeds particular thresholds (40a,40b), integrators (42a,42b) integrate the output. The maximum integrated values sensed about the tire (12) are stored (44a,44b) and displayed (46a,46b).
