The Konig Ampliform wheel comes in 18x8.5 with a 5x108 bolt pattern and an ET43 offset, finished in Gloss Bronze. It is a replacement for a wheel of the same bolt pattern, with the size and offset deciding tire fit under the fender.
A wheel is the rim the tire mounts on; it bolts to the vehicle's hub, and its diameter, width, bolt pattern and offset set how the tire sits under the fender.
