Abstract
A method for correcting errors of measurement due to variations in tire pressure in a tire uniformity inspecting operation, wherein a tire is inflated and rotated between a pair of rims and a load wheel is pressed against the tire and a radial force variation of said tire is measured, including: detecting a deviation of actual air pressure of the tire from a predetermined measuring pressure level to determine a correction coefficient; calculating a value of tire uniformity from the measured value of radial force variation according to the predetermined measuring pressure level; multiplying the calculated value of uniformity by the correction coefficient to compensate for any erroneous component due to a variation in the tire pressure.
