A vehicle’s wheel mounting configuration is defined by the number of bolt holes and the diameter of the circle they form. For example, a “4×108” configuration indicates four bolt holes positioned on a circle with a diameter of 108 millimeters. Similarly, “4×114.3” denotes four bolt holes on a 114.3 millimeter diameter circle. These measurements are critical for ensuring wheel compatibility.
The specification is crucial for vehicle safety and performance. Employing wheels with an incorrect specification can prevent proper wheel installation, leading to potential wheel detachment during operation and posing significant safety risks. The origin of diverse specifications stems from variations in vehicle design across different manufacturers and models over time.
