The wheel mounting configuration for the 2008 Buick Lucerne utilizes a specific arrangement of studs and corresponding lug nuts. This configuration, often expressed numerically (e.g., 5×115), defines the number of wheel studs and the diameter of the circle upon which they are positioned. For the 2008 Buick Lucerne, the standard wheel mounting uses five studs arranged on a circle with a diameter of 115 millimeters. This measurement ensures proper wheel fitment and secure attachment to the vehicle’s hub.
Correct wheel installation is critical for vehicle safety and performance. Using wheels with an incorrect mounting specification can lead to wheel instability, vibration, and, in extreme cases, wheel detachment. The specific design ensures wheels are centered correctly on the hub, distributing load evenly and preventing damage to the wheel bearings and suspension components. This standardized dimension also facilitates wheel interchangeability within certain vehicle models and generations, offering aftermarket options for customization and replacement. Early vehicle designs often lacked standardization, leading to compatibility issues; the current configurations are a result of design evolution focused on safety and ease of maintenance.
