Abstract
A tire includes at least a pair of breaker plies each having a plurality of wire codes of different orientation. In a tire testing apparatus, a tire is loaded to a test position and electromagnetic wave having a wavelength equal to or shorter than X-ray is irradiated to transmit a tread surface of one of test portions of the tire loaded at the test position. A detector detects the electromagnetic wave to produce a test image signal. A measuring section executes a processing of at least one test item on the pair of breaker plies to a test image data and automatically determines whether the test position of the tire is defective or non-defective, from the processing result of the test image data. A control section determines whether all the test portions of the tire are tested, when the tire is determined to be non-defective at the one test portion, issues a rotate command to rotate the tire for another test position if all the test portions of said tire are not yet ended, and issues a first unload command if all the test portions are ended.
