When searching for aftermarket Mustang or Lightning wheels, you may have come across the terms “lug-centric” or “hub-centric”. However, you may not know what the terms mean or why they are important. They focus on how the wheel itself centers on a vehicle’s hub in order to prevent any vibration.Lug-Centric Wheels
Lug-centric wheels are centered on the mounting surface using the lug holes. Most aftermarket wheels are lug-centric because this allows the manufacturer to make the wheels with larger hub bore diameters so that the wheel can fit a wider array of vehicles. Manufacturers make the center bore larger because a center bore that is smaller than the vehicle hub will not be able to secure safely to the vehicle.
Hub-centric wheels are designed for the hub center bore of the wheel to be a perfect fit to the vehicle. This allows the weight of the vehicle to rest on the center bore of the wheel, rather than the lug bolts. Most original equipment wheels are designed to be hub-centric because the manufacturer designs wheels specifically for each vehicle or vehicle line.
Hub-centric rings (hub rings) can be installed on lug centric wheels. A hub-centric ring is a plastic or metal ring that sits inside the hub bore and on the hub of the axle, filling the gap between the hub bore and the hub. Hub rings essentially make lug-centric wheels hub-centric.
