This specification refers to the configuration of lug nuts on a vehicle’s wheel hub. It indicates the number of lug nuts and the diameter of the circle they form. For instance, a “5×114.3” specification signifies five lug nuts arranged on a circle with a diameter of 114.3 millimeters. This measurement is crucial when selecting aftermarket wheels or ensuring proper wheel fitment.
Adherence to the correct specification is paramount for vehicle safety and performance. Using wheels with an incorrect configuration can lead to wheel detachment, causing accidents and potential damage. Historically, manufacturers have utilized various configurations, necessitating careful verification when replacing wheels or considering modifications. Understanding this configuration helps ensure compatibility, optimal weight distribution, and secure wheel mounting.
