out-of-round tires.
Out-of-roundness can only be measured as a radial force variation and most tire dealers do not have the equipment necessary to make this measurement.
Because of this, the most effective way to inspect for this condition is to use a specific diagnostic procedure to rule out or confirm other causes for the
vibration. The following pages of this Technical Bulletin contain a procedure that can be used to confirm/eliminate tire out-of-round as a cause of vehicle
vibration. Listed are the lateral and radial runout specifications for the 1989 Nissan models to assist you when performing the procedure.
