A high-voltage, non-destructive inspection system for detecting nails, and/or cuts and holes in vehicle tires. The system employs a high-voltage head mounted within the tire and a reference head outside the tire opposite to the high-voltage head. The high-voltage head and reference head span the tire tread axially. The inspection is performed in one revolution of the tire. High-voltage pulses are impressed upon the high-voltage head, and the amplitude and pulse widths are variably selected, commensurate with the type of tire being tested. When a cut, hole or a nail in the tire passes between the high-voltage head and the reference head, an electric arc forms and current passes through the tire. This arc can be visually observed and also electronically detected. Upon detection, via an electronic detection circuit, a lamp lights and the tire rotation is stopped, thus facilitating location of the flaw, via a manual mode.
