Disc sizes of Isuzu Impulse
General parameters:
  • Offset (ET): from 20 to 48;
  • Drilling (PCD): 4x100;
  • Center hole (DIA): 56.6.

Important: wheel disc parameter PCD indicates not only the diameter of circumference of the mounting holes, but also the number of mounting bolts or nuts (for example: 5x120, where 120 (mm) is the diameter of centers of the mounting holes, and 5 is the number of mounting bolts).

Possible disk sizes for Isuzu Impulse:
  • 14x5.5
  • 14x6.0
  • 15x6.5
  • 16x7.0
  • 17x7.5
Procedure for calculating the disc 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 formula for calculating:

ET = A - B/2, where:

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

B is disk width.

The disk offset affects the width of the vehicle wheelbase, since the distance between the centers of symmetry (in width) of wheels on one axis directly depends on this parameter.

Important: PCD of disks with four fixing bolts (or nuts) corresponds to the distance between the centers of opposite bolts (or nuts), PCD of disks with five fixing bolts (or nuts) corresponds to the distance between the centers of any non-adjacent bolts (or nuts) multiplied by the coefficient 1.051.
