The arrangement of mounting holes on a vehicle’s wheel hub, specifically referencing a 2012 Buick Regal, is a critical measurement. This specification dictates the compatibility of wheels to the vehicle. For instance, a specific number of lug bolts are arranged on a circle of a defined diameter, usually expressed in millimeters.
Correct specification adherence is paramount for safe and effective wheel installation. Selecting wheels with a matching specification ensures proper centering and secure fastening, preventing vibration, wheel detachment, and potential damage to the vehicle’s hub and wheel studs. Historically, this measurement has evolved across different vehicle makes and models, reflecting advancements in automotive engineering and manufacturing standards.
