<p>A method and apparatus for testing tires. In step (110), the radial force variation is measured in the current direction of rotation. The first harmonic of this force variation is calculated in step (120) and a tire position corresponding to either zero crossing of the first harmonic is determined in step (130). In step (140), the tire position is monitored until a zero crossing is reached. The rotation direction is reversed at the appropriate location in step (150) and the test is continued.</p> |
