ABSTRACT:
In a method and apparatus for improving the fit of a pneumatic tire on a motor vehicle wheel rim, before a wheel balancing operation is carried out the wheel is accelerated to a maximum permissible peripheral speed and centrifugal force acting at the wheel is measured at that speed. The drive for the wheel with tire thereon is stopped when the measured variation in centrifugal force reaches or falls below a predetermined limit value.
