Abstract
The operating or running characteristics of a vehicle tire or rim with a tire secured thereto are optimized on one and the same machine. For this purpose the tire or wheel is supported on a subcritically tuned support bridge structure and driven by a spindle with an adjustable r.p.m. The vibrations of the support bridge structure are measured and converted into respective electrical signals representing a wheel unbalance and/or tire non-uniformities while a drum is pressed with a predetermined force against the tire or vice versa. This force is also measured as an electrical signal. An angular position sensor is operatively connected to the tire or spindle and provides an electrical signal representing the instantaneous tire or wheel position relative to a polar coordinate system.
