The rim and wheel runout measurements are automatically made during the unbalance measurement cycle and no
extra time is required.
The purpose of these measurements is to check whether it is possible to reduce the total wheel runout by turning
only the tyre on the rim.
The information shown on the screen is:
Grey rim: outer tyre surface
Yellow rim: rim surface
: Tyre runout position (moved by turning the wheel)
: Rim runout position (moved by turning the wheel)
