Balancing/Optimizing Wheels: General: Notes
WARNING: This page is about a different car, the 2020 Porsche Panamera, 2019 Porsche Panamera, 2018 Porsche Panamera, and 2017 Porsche Panamera. However, it is still accessible from the selected car via links, so may be relevant.
Excessive rough running of the wheels, caused by wheel imbalance, flat spots and misshapen tyre structures causes vibrations and shaking in the steering wheel. This in turn leads to increased wear on various parts of the chassis.
Even if wheels are correctly balanced, rolling and steering imbalance can still occur. For example with:
- Excessive geometric errors (radial and lateral runout)
- Radial force variations (softer and more rigid areas in the tyre)
