ABSTRACT:
A method for correcting tire imbalance of a tubeless pneumatic vehicle tire includes the step of mounting the tire on a master wheel rim of great manufacturing precision and having a design that is identical at least in its seat surface to commercial wheel rims for the tire. The tire is inflated to a pressure within a range of -0.3 bar to +0.2 bar of a maximum operating pressure. The pneumatic vehicle tire mounted on the master wheel rim is pressed against a measuring device. At least one radial parameter is measured. The values of the radial parameter are recorded as a function of the angle of rotation from 0.degree. to 360.degree. of the tire. The maximum and the minimum of the radial parameter is determined and the difference between the maximum and minimum is calculated. The difference is compared to a predetermined threshold value. The bead of the tire, when the difference between the maximum and the minimum is above the threshold value, is corrected. Correction includes the step of removing at locations, where the value of the radial parameter is greater than the minimum plus the threshold value, tire material from the radially inwardly facing seat surface of the tire bead at least to such an extent that the remaining tire imbalance is within a given tolerance range.
