The configuration specifies the arrangement of lug nuts securing the wheel to the vehicle’s hub. Specifically, it defines the diameter of the circle on which the lug nuts are positioned and the number of lug nuts present. For example, a measurement might be expressed as 8×6.5″, indicating 8 lug nuts arranged on a circle with a diameter of 6.5 inches.
This specification is crucial for ensuring compatibility between the vehicle’s hub and aftermarket wheels. Selecting a wheel with the incorrect configuration can lead to unsafe driving conditions, potential damage to the vehicle, and the inability to properly mount the wheel. Historically, variations in configurations have been common across different vehicle manufacturers and models, necessitating careful attention when choosing replacement or upgraded wheels. Proper matching ensures that the wheel is centered correctly and that the load is distributed evenly across the lug nuts.
