Note
♦
To mount wheel on wheel balancer, use for example Wheel
Centering System Adapter - VAS5271- .
♦
This way a 100% centering of the wheel and gentle mounting
is possible!
♦
It is not possible to center it 100% on balancing machine with
conical tensioners.
♦
With a deviation of 0.1 mm outside the center, there is an im‐
balance of 10 grams on the wheel/tire.
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.
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 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
⇒ “12.8 Wheels and Tires, Checking Radial and Lateral Run-
Out with Tire Dial Gauge VAG1435 ”, page 286 .
– If the radial and lateral run-out are within the specified toler‐
ance, 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 ⇒ “12.10 Matching”, page 287 .
♦
The display in the balancing machine should show 0 grams.
♦
Hunter RFT33VAG Road Force Touch™ Wheel Balancer -
VAS6230B4- can be inserted as an alternative to matching.
Refer to
⇒ “12.5 Hunter RFT33VAG Road Force Touch™ Wheel Bal‐
ancer VAS6230B4 ”, page 284 .
– 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.
