The wheel studs closest to the tire valves are marked with red or yellow paint to ensure correct reinstalling of the balanced wheels. The lockable wheel nuts must be installed on these studs.

It is recommended to mark other cars accordingly before removing wheels.

All Models When balancing front wheels on car, the steering should be in straight ahead position for optimum results.

Off Car Balancing

Prior to balancing wheels with lockable wheel nuts off car, a 5 gram weight should be installed above the tire valve stem on the wheel rim to compensate for the additional weight of the lockable wheel nut. After balancing is completed, this weight must be removed.
