The configuration used to secure a wheel to a vehicle hub on the Pontiac G8 is a critical specification. This configuration, often expressed in a numerical format, indicates the number of lug studs and the diameter of the circle they are arranged on. For instance, a designation of 5×120 means there are five lug studs situated on a circle with a 120mm diameter.
Correct wheel fitment is paramount for both vehicle safety and optimal performance. Using wheels with an incorrect configuration can lead to wheel detachment, component damage, and compromised handling. The specified configuration for the G8 ensures proper load distribution and secure attachment, maintaining the vehicle’s designed handling characteristics. Furthermore, utilizing the correct configuration prevents undue stress on the wheel studs and hub assembly. The information regarding this specification is essential when selecting aftermarket wheels or replacing existing ones.
