Wheel/Tire Balancing Procedure
-- Let the wheel/tire turn on the balancing machine.
-- Check the run of the characteristic lines on the sidewall of the tire in the area of the rim flange.
-- Check the tire wear pattern while the wheel/tire is turning.
-- Check the run-out on the wheel/tire. If the wheel with tire runs untrue although there are no flat spots, a radial or lateral run-out may be the cause.
-- Check wheel with tire for radial- and lateral run-out. Refer to WHEEL AND TIRE RADIAL AND LATERAL RUN OUT, CHECKING WITH TIRE DIAL GAUGE .
-- If the radial and lateral run-out are within the specified tolerance, balance the wheel and tire.
Do not use more than 60 grams of weight per wheel.
If more weight is necessary, a smoother running can achieved by matched mounting of the tire. Matched mounting of tire. Refer to WHEELS AND TIRES, MATCHING .
The display in the balancing machine should show 0 grams.
Road Force Measurement System VAS 6230A can be inserted as an alternative to matching. Refer to VIBRATION CONTROL SYSTEM .
-- Install the wheel on the vehicle.
-- First, tighten the lowest wheel bolt by hand to approximately 30 Nm.
-- Tighten the remaining wheel bolts diagonally to approximately 30 Nm. This process centers the wheel on the wheel hub.
-- Lower vehicle onto its wheels.
-- Now use a torque wrench to tighten the wheel bolts diagonally to the specified tightening specification.
