Checking Cast Rim Runout

The die-cast wheels should be checked for lateral and radial runout before installing a new tire or tube.

1. See Figure 2-18A. Install arbor in the wheel hub and place wheel in the truing stand. To check rim lateral runout, place a gauge rod or dial indicator near the rim bead. If lateral runout exceeds 3/64 in., replace the wheel.

2. See Figure 2-18B. Check for radial runout as shown here. Replace the wheel if runout exceeds 1/32 in.
