The configuration of mounting holes on a wheel and the corresponding hub of the vehicle describes the arrangement used to secure the wheel. This specification is defined by the number of bolts and the diameter of the circle they are positioned on, measured in millimeters. As an illustration, a “5×108” notation indicates that there are five bolts situated on a circle with a diameter of 108 millimeters.
Correct identification of this specification is crucial for ensuring wheel compatibility. Using wheels with an incorrect specification can lead to wheel detachment, posing a significant safety risk and potentially causing damage to the vehicle. This specification has evolved over time, with variations arising from different vehicle manufacturers and models. Understanding the correct specification for a specific vehicle is essential for safe and reliable operation.
