Abstract
A method for correcting errors of measurement in a tire uniforming inspecting machine having a pair of upper and lower rims engageable with bead portions of a tire for gripping the tire securely for rotation at a predetermined position and a load wheel engageable with the circumference of the tire at one side thereof to check for variations in the radial force, including: measuring radial runout of the rims and/or load wheel to obtain an erronous deflection signal indicating the amount of radial runout of the rims and/or load wheel; obtaining and storing a primary harmonic component of the erroneous deflection signal; measuring variations in radial force of a tire rotated on the rims to obtain a radial variation signal for a period of one revolution of the tire; multiplying the erroneous deflection signal by a spring constant of the tire to obtain an erroneous variation signal; and subtracting the erroneous variation signal from the radial variation signal to eliminate influence of radial runout of the rims and/or load wheel from the measured value of the radial force of the tire.
