Official summary

This is a Technical Journal: we find with automobiles. Radial force variation ( RFV ) is a condition where excessive run out will create the same symptom as an unbalanced tire. Tire balancing should be checked and corrected as needed but is not always the solution. Road Force balancing detects assembly run out measured under load simulating real world driving conditions and will provide a solution to match mount the tire and rim to minimize loaded run out.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
