Abstract
The magnitude of a variable property of a tire such as the dynamic imbalance may be predicted by measuring lateral runout at positions close to the end of the tread pattern on both sides of the tire and determining the first harmonic runout values. The first harmonic runout values relative to the centerplane of the tire at different circumferential positions around the tire are arithmetically added. The largest sum at any point on the circumference of the tire gives an indication of the maximum dynamic imbalance of the tire. Tires can be screened by the system comparing this sum with predetermined amounts corresponding to the maximum acceptable dynamic imbalance or other standards and providing visual signals identifying those tires with the largest sum exceeding this predetermined amount or the other standards.
