The specification indicates the arrangement of the lug nuts or bolts used to secure a wheel to a vehicle’s hub. It is defined by the number of bolts and the diameter of the circle they form. For example, a “5×114.3” configuration signifies five lug holes arranged on a circle with a diameter of 114.3 millimeters. Understanding this measurement is crucial when replacing wheels or ensuring compatibility with aftermarket options.
Correct wheel fitment is essential for vehicle safety and performance. Using wheels with an incorrect specification can lead to wheel stud damage, vibration, and potential wheel detachment. Historically, variations existed across different models and years; however, standardization has become more prevalent. Proper adherence to these specifications ensures optimal load distribution and handling characteristics.
