The configuration of lug nut placement on a wheel hub, specifically regarding the number of studs and the diameter of the circle they form, is a critical specification for vehicle compatibility. For example, the arrangement associated with a specific General Motors sport utility vehicle is essential for ensuring proper wheel installation and safe vehicle operation. This arrangement dictates which wheels can be correctly and securely mounted to that vehicle.
This specification is vital because it directly impacts the safety and performance of the vehicle. Using wheels with an incorrect arrangement can lead to wheel detachment, potentially causing accidents and damage. Throughout its production run, adherence to a standardized configuration provided consistency and allowed for interchangeability within specific model years. Furthermore, this consistent design simplified aftermarket wheel selection and ensured owners could find compatible options.
