The configuration of mounting holes on a wheel hub, specified by the number of studs and the diameter of the circle they form, is crucial for ensuring proper wheel fitment. An example is a 5×100 configuration, indicating five studs positioned on a circle with a 100mm diameter. This specification must match the wheel’s corresponding pattern for secure attachment.
This measurement is essential for vehicle safety and performance. Using wheels with an incorrect specification can lead to wheel detachment, potentially causing accidents. Furthermore, understanding this measurement facilitates wheel selection, allowing owners to choose appropriate aftermarket options or replace damaged wheels with compatible alternatives. Historically, standardization of these configurations has simplified wheel manufacturing and distribution, contributing to cost-effectiveness and wider availability.
