Weights will now be displayed on the control panel. The weight in
the left display is the weight imbalance for the rim (as indicated by
the RIM light below the display). The weight in the right display is the
weight imbalance for the tire (as indicated by the TIRE light below the
display).
Use these weights to determine the suitability of the rim or tire.
High imbalance may indicate a rim that is out-of-round or misformed,
or a tire with a bubble or other problem. If the imbalance is exces-
sive, it may be prudent to replace the rim, the tire, or both. If either
is replaced do not continue this procedure. Balance the new tire and
rim and evaluate the readings for Match Mount suitability.

where the other memory was selected.
