Wheel/Tire Balancing Procedure

-- Let the wheel and tire rotate on the wheel balancer.

-- 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 and tire are rotating.

NOTE: In the event of one-sided wear, flat spots from braking or severe wear spots, smooth running cannot be achieved by balancing. In this case, the tire must be replaced.

-- Check the run-out of the wheel and 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 CHECKING WHEEL AND TIRE RADIAL AND LATERAL RUN OUT, WITH Tire Dial Gauge VAG 1435 .

-- If the radial and lateral run-out are within the specified tolerance, balance the wheel and tire.

NOTE:

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 MATCHING .

The display in the balancing machine should show 0 grams.

Road Force Tire Balancer VAS 6230A can be inserted as an alternative to matching, refer to Road Force Tire Balancer VAS 6230A .

-- Bolt the wheel to the vehicle.

-- First, tighten the lowest wheel bolt by hand to approximately 30 Nm.

-- Now tighten the remaining wheel bolts diagonally also to about 30 Nm. This process centers the wheel on the wheel hub.

-- Put the vehicle on its wheels.

-- Now use a torque wrench to tighten the wheel bolts diagonally to the specified tightening specification.
