Further To 2B: Stationary Balancing With Rolling Smoothness Optimization

WARNING: This page is about a different variant/trim than selected.

Clamp wheel on stationary balancing machine.

Follow the operating instructions for the relevant balancing machine. Adjust the balancing machine according to the manufacturer's instructions (if necessary).

The contact surface of the wheel on the balancing flange (flat surface) and the centring surface must be clean.

Centre (clamp) the wheel from the inside using centring clamping device - see the appropriate Service Information . This centring clamping device fits all wheel-balancing machines approved by Porsche.

Check radial and lateral runout during the first measuring run. Values of less than 1.0 mm are desirable - around 0.5 mm would be better.

Consider the size of the measured balance weights and their distribution on the inner and outer planes (inner and outer rim flanges) critically.

A uniform distribution with low values (e.g. 35/45 g) means that the tire was fitted correctly and the quality of the tire and rim is good.

A value of 90 g/90 g should not be exceeded with interior balancing behind the wheel center. A considerably different distribution, e.g. 35/90 g is not good; this usually indicates incorrect fitting. Problem wheels of this kind often have pronounced radial and lateral runout values.

This can be remedied by matching (use correct mounting paste). This can be improved with uncontrolled matching (manual); significant improvement is possible in almost all cases using the rolling smoothness optimization program (controlled matching).

Tire pressure during balancing at required pressure.

Permissible residual imbalance of less than 3 g, or max. 3 g per plane.
