The present invention provides a method and apparatus for accurately detecting shoulder edge wear without impairing the durability of a tire. The method includes extracting an acceleration waveform from output signals of an acceleration sensor (11) disposed on the inner surface of a tire tread by an acceleration waveform extracting means (12), extracting either a pre-leading-end region or a post-trailing-end region of the acceleration waveform by an acceleration waveform separating means (13), obtaining a frequency spectrum by analyzing the extracted acceleration waveform by a frequency analysis means (14), calculating a frequency band value, which is the magnitude of acceleration in a specific frequency band, from the frequency spectrum by a frequency band value calculating means (15), and detecting an uneven wear in the edge of the tire shoulder from the magnitude of the calculated frequency band value by a shoulder edge wear detecting means (17).
