Abstract
A process and an apparatus for testing the uniformity of a pneumatic tire such as a vehicle tire provide that fluctuations in tire inflation pressure are measured during a uniformity-testing measuring run in which the tire to be tested is rolled against a test surface under a given loading, with force fluctuations occurring at the contact surface therebetween, and in which a compensation value is formed from the measured fluctuations. The compensation value is combined with the measured force fluctuations thereby to eliminate force fluctuation components attributable to fluctuations in the tire inflation pressure.
