An important problem in retreading tires is the assurance of a satisfactory casing. Since 1972 the National Highway Traffic Safety Administration has had under development an air-coupled through-transmission ultrasonic inspection system for finding anomalies in casings. The report describes the results of this development in sufficient detail to permit its reproduction by a reasonably competent electronics manufacturer. The reader is cautioned that the equipment described will not find all anomalies in every casing, and that system cost effectiveness depends heavily on the way the equipment is used, the tires it inspects, and the types of anomalies considered to be detrimental to retreading.
