A configuration describes the arrangement of lug holes on a vehicle’s wheel hub and the corresponding wheel. The designation indicates the number of lug holes and the diameter of the circle they form. Therefore, a “5×120” configuration signifies five lug holes positioned on a circle with a 120mm diameter, while “5×5” (or 5x127mm in metric equivalent) denotes five lug holes on a circle with a 5-inch (127mm) diameter.
Understanding wheel bolt patterns is crucial for ensuring proper wheel fitment and vehicle safety. Installing wheels with an incorrect configuration can lead to wheel instability, vibration, and potential damage to the vehicle’s wheel hubs and suspension components. Historically, different vehicle manufacturers have adopted various standards, resulting in a wide range of configurations found across different makes and models. Choosing wheels with the correct configuration guarantees secure attachment, optimal performance, and adherence to safety standards.
