PCD stud pattern diagram

PCD

PCD is the stud pattern. On many Commodores this is written as 5x120, meaning five wheel studs on a 120 mm circle. The PCD must match the car.

EA example: Holden Commodore 5x120
Wheel offset and mounting face diagram

Offset / ET

Offset is how far the wheel mounting face sits from the wheel centre. It changes how far the wheel sits in or out, and affects guards, suspension and brakes.

Lowered, deep dish and staggered cars need this checked carefully.
Centre bore hub opening diagram

Centre bore

Centre bore is the hole in the middle of the wheel that fits over the hub. If the bore is larger than the hub, hub rings may be needed for a clean fit.

VE/VF and earlier Commodores use different centre bore sizes.
Tyre size and rolling diameter diagram

Tyre size

Tyre size affects ride comfort, guard clearance, load rating and speedometer reading. Bigger wheels usually need a lower-profile tyre to keep diameter close.

Use the calculator above before choosing 20s or 22s.
