Dimensions discs
Formula for calculating the disk offset:

The distance between mating face of the wheel (the face with which the disk is pressed against the hub) and the middle of the width of disk is called disk offset (ET), the offset is calculated using the following formula:

ET = A - B/2, where:

A is the distance between the inner face of the disk and the part in contact with the hub;

B is disk width.

Important: the main parameters of vehicle wheel discs have the following units: width (inches), diameter (inches), diameter of circumference of the mounting holes (mm), disk offset (mm), diameter of a center hole (mm).
