Further to 2: Stationary balancing with optimization of the rolling smoothness

• Clamp wheel on stationary balancing machine.
• Observe the operating instructions of the balancing machine; occasionally adjust the machine if necessary.
• The support surfaces of the wheel on the balancing flange (levelling surface) and the centering surface must be clean.
• Centre (clamp) the wheel from the inside with centering clamping device. This centering clamping device fits on all wheel balancing machines approved by Porsche.

Check radial and axial runout during the 1st measuring run. Values less than 1.0 mm - better around 0.5 mm - are desirable.

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

A uniform distribution with low values (e.g. 25/30 g) means that the tire was mounted correctly and the quality of the tire and rim is good.

A value of 80/80 g should not be exceeded. A greatly different distribution, e.g. 30/70 g is very unfavorable; this usually indicates incorrect mounting. Problem wheels of this kind often have pronounced radial and axial runout values.

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

The tire pressure must not be less than 1.5 bar overpressure during balancing.

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