PURPOSE: A tire wearing measure system is provided to accurately and rapidly measure the abrasion degree of front and rear side of a tire by using a single image and cosine grating. CONSTITUTION: A tire wearing measure system comprises a light source member(100) and a digital camera member(300). The light source member uses a cosine grating included in a lens in order to emit light to a tire surface(200) before or after driving. The digital camera member measures the intensity of the light emitted to the tire surface. The digital camera member indicates the abrasion degree of tire surface as data of single image type. The digital camera member converts the abrasion degree of the tire surface into data by calculating displacement information and phase information after the Fourier conversion of light intensity.
