Rim Runout Measurements
Rim runout can be measured externally with the tire mounted to the rim bead seats,
or the bare rim can be measured separately for more precise measurements. If the
assembly does not have a flat faced rim, take the runout measurement.
Refer to “Rim
Runout External Measurement (Tire and Wheel Assembly),” below. If the assembly is
flat faced, and you are prompted by the
GSP9720JLR to take runout data, or to verify
the runout data already taken with the tire in place, take the runout measurement as
described in “Rim Runout Measurement (Bare Rim),” page 65.
Bare rim measurement is a more accurate method of measuring rim runout. Bare rim
measurements can also be used to audit bare rims prior to the installation of a tire.
Runout can be viewed by selecting “Show Runout & Road Force” from the “Balance”
primary screen.
Single Arm Rim Runout External Measurement (Tire and Wheel Assembly)
The inner Dataset® Arm can be used alone externally to measure rim runout of the
inboard bead seat. This method is not as accurate as two position measurement, but
it is faster for QuickMatch® predictions.
Dual Arm Rim Runout External Measurement (Tire and Wheel Assembly)
If the GSP9720JLR determines that there is a problem with the wheel assembly, it
will prompt you to measure rim runout. The “Measure Rim Runout” popup screen can
be selected from the “Balance” primary screen, or by pressing the outer arm button
once. To measure rim runout with the tire on the rim, remove all clip-on weights from
the rim and place the inner and outer Dataset® arm on the rim as shown below:
