The 18 X 9 Inch Black Machined Face Wheel Rim with a 5x114.3 / 5x127 bolt pattern and ET 10 offset, CB 83.6 specifications can be described in the following way:
Parameters and Descriptions:
Size: 18 x 9 inches
This indicates the diameter and width of the wheel. The diameter is 18 inches, and the width is 9 inches.
Bolt Pattern: 5x114.3 / 5x127
This refers to the number of bolt holes and the distance between them.
5x114.3: This means the wheel has 5 bolt holes, and the distance between the centers of two holes is 114.3 mm.
5x127: This indicates another bolt pattern option, with 5 bolt holes, but the distance between centers of two holes is 127 mm.
Offset (ET 10):
The ET (Einpresstiefe), or offset, is 10 mm. This is the distance from the wheel's centerline to the mounting surface of the wheel. A positive offset means the mounting surface is towards the outside (away from the centerline), and a low positive offset like 10 mm indicates a relatively shallow position.
Center Bore (CB 83.6):
The center bore is the diameter of the hole in the center of the wheel that fits onto the vehicle's hub. In this case, it is 83.6 mm. It's important that the center bore matches the hub diameter of the vehicle for proper fitting. If it's larger, a hub-centric ring may be used.
Finish: Black Machined Face
This refers to the appearance of the wheel. It has a black finish with a machined face, meaning the central part of the wheel is machined to provide a shiny, polished appearance, while the rest of the wheel retains a matte or gloss black finish.
These parameters determine the fitment and appearance of the wheel on a vehicle, so they need to match the vehicle's specifications in terms of bolt pattern, center bore, and offset for proper installation and performance.
