The arrangement of lug nuts on a vehicle’s wheel hub, specifically in reference to a particular model, dictates the compatibility of wheels with that vehicle. This arrangement is defined by the number of lug nuts and the diameter of the circle they form. For example, a configuration might be designated as 5×114.3, indicating five lug nuts positioned on a circle with a diameter of 114.3 millimeters.
This configuration is a crucial factor in vehicle safety and performance. Ensuring proper wheel fitment prevents potential issues such as wheel detachment, uneven tire wear, and compromised handling. Historically, these configurations have evolved to accommodate increasing vehicle weight, power, and braking capabilities. The design is a foundational element in vehicle engineering, balancing structural integrity with ease of maintenance.
