ABSTRACT:
A device for testing a tire that has a tread and extending sidewalls includes an apparatus for receiving and rotating a tire and at least one measurement device operatively placed to measure at least one of the sidewalls as the tire is rotated wherein the measurement device is radially moveable with respect to the sidewall in defined increments so as to obtain a measurement profile for each radial position. A controller is connected to the measurement device and receives each measurement profile, wherein the controller classifies the measurement profile into slope classifications, and wherein the controller monitors the slope classifications for defective patterns and, if detected, monitors a second measurement profile for another defective pattern. If another defective pattern is detected in the second measurement profile in the same radial region, the controller generates an indication that the tire is defective.
