The configuration of the mounting holes on the wheel hub of a 2008 Ford Fusion follows a specific design. This arrangement, which includes the number of bolts and the diameter of the circle on which they are positioned, is crucial for ensuring proper wheel fitment and safe vehicle operation. For this model year, it is a 5×114.3mm (or 5×4.5 inch) configuration. This indicates five equally spaced bolt holes arranged on a circle with a diameter of 114.3 millimeters (or 4.5 inches).
Understanding this dimensional specification is paramount for several reasons. It allows vehicle owners to select replacement wheels that are compatible with their vehicle’s hub. Furthermore, it is vital for technicians performing wheel alignments or tire rotations to ensure the correct tools and procedures are used. Selecting an incorrect wheel bolt pattern could lead to wheel instability, vibration, and potentially catastrophic wheel detachment while driving. Historically, standardization of these specifications has improved safety and ease of maintenance across different vehicle models.
