Disc sizes of Buick

home ⇒ equipment ⇒ wheel disks

Minimum tire size for the entire range of Buick models is: 56.1 (mm).

Limit parameters for all models:
  • Tire size: from 56.1 to 70.3;
  • Disk size: from 2 to 55.
Possible disk sizes for Buick (Бьюик):

Important: main parameters of a vehicle wheel: width (B), diameter (D), diameter of circumference of the mounting holes (PCD), disk offset (ET), diameter of a center hole (DIA).
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.

There are discs with a negative offset and a positive offset, if the middle of the disc matches the face of attachment of the disc to the hub, then the disc offset will be zero.

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).
