Volkswagen Golf Service & Repair Manual: Balancing wheel, checking radial and lateral run-out of wheels and tyres
| Before you start balancing the wheels, the following
requirements must be met. |
| Tyre pressure must be OK. |
| Tread must not be worn on one side. Tread depth should be at
least 4 mm. |
| The tyre must not show any signs of damage, for example
cuts, piercing, foreign bodies, etc. |
| Wheel suspension and steering, including shock absorbers,
must be in perfect condition. |
| Road test has been carried out
→ Chapter. |
| Radial and lateral run-out occur when the wheel and tyre do
not run absolutely true. |
| For technical reasons, 100% true running is not possible. |
| Therefore, the manufacturers of these components allow a
precisely determined tolerance. |
| Aligning the tyre in an unfavourable position on the wheel
can cause the maximum allowed tolerance for wheel with tyre to
be exceeded. |
| – |
Preload tyre gauge approx. 2 mm. |
|
|
|
| – |
Fit tyre gauge to side wall of tyre. |
| – |
Make a note of the smallest and largest deflection of the
indicator needle. |
 Note
| If the difference is greater than 1.3 mm, the lateral
run-out is too great. |
| In this case, the radial run-out can be reduced by matching
wheel and tyre
→ Chapter. |
| Extreme values on the tyre gauge due to small irregularities
in the rubber may be disregarded. |

Preload tyre gauge approx. 2 mm. |
|
|
|
| – |
Fit tyre gauge to running surface of tyre. |
| – |
Make a note of the smallest and largest deflection of the
indicator needle. |
Note
| If the difference is greater than 1 mm, the radial run-out
is too great. |
| In this case, the radial run-out can be reduced by matching
wheel and tyre
→ Chapter. |
