ELEMENT

The surface coating or treatment applied to enhance appearance and durability.

The arrangement of the lug holes used to attach the wheel to the vehicle's hub. It's expressed as two numbers: the number of lug bolts and the diameter of the circle formed by their centers.

The distance between the wheel's mounting surface (where it attaches to the hub) and the centerline of the wheel.

The hole in the center of the wheel that connects with the vehicle's hub.

The distance from the wheel's mounting surface to the inner lip of the wheel, measured in inches.

The main color(s) of the wheel face chosen for both aesthetic and functional reasons.

The number of spokes on a wheel generally relates to its strength and durability, with more spokes often indicating a more robust wheel. This is usually chosen based on aesthetics and a balance of wheel spokes to open space can facilitate airflow to keep brakes cooler in high use and high temperatures.
