A positioning arm (44) is provided with a plurality of elongated members carrying two combinations of a radiation source (46; 58) and a sensor (48; 60). Each sidewall is interposed between a radiation source (46; 58) and a sensor (48; 60). The radiation sources (46; 58) provide a collimated beam of radiation which is relatively unattenuated (absorbed) in passing through the elastomer in the tire sidewall, but will be reflected by the steel wire cords in the sidewall. Each combination of a radiation source and sensor scans a sidewall of the tire at a predetermined speed to detect sidewall defects such as missing or improperly spaced cords.
