In the tire examination method before and after an alteration in the tire pressure a respective interferogram is produced of the tire surface using coherent radiation and the interferogram is converted into a modulo 2 pi image, which for its part is processed to obtain a gray value image and in the case of which from a comparison of the gray value images information concerning any defects present in the tire is obtained. For testing a tire the wheel, which bears such tire to be tested, is arranged on a driven roller set by driving the vehicle with the wheel, a test head is moved toward the tire to be at a predetermined test distance therefrom for producing such interferograms, at a first test segment of the tire examination for defects is performed, the wheel is incrementally rotated by the roller set by an amount equal to the size of a test segment and so many test segments are examined that the complete tire is tested. The tire testing apparatus possesses an air pressure means for altering the tire pressure, a test head and a computer.
