A Opel Commodore (1972–1978) uses a 5x120 PCD and a centre bore of 69.5 mm.
Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.
Centre bore: the wheel must have a centre bore of 69.5 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 69.5 mm.
Offset: the original is ET38. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
Fixings: thread -. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Vehicles with the same PCD and centre bore
Same 5x120 PCD and same 69.5 mm centre bore: wheels from these vehicles bolt on and centre on a Opel Commodore without rings. Offset, width, diameter and caliper clearance still need checking.
Will wheels from another vehicle fit your Commodore?
Choose the vehicle the wheels come from: we compare the hub, then each original wheel to the millimetre.
Same PCD, different centre bore
These vehicles also use 5x120 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 69.5 mm, and will not fit if it is smaller.
A Opel Commodore (1972–1978) has a PCD of 5x120: 5 studs or bolts spaced around a circle 120 mm in diameter.
Does a Opel Commodore need a hub centric ring?
The centre bore (hub diameter) of a Opel Commodore is 69.5 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.
What offset (ET) for a Opel Commodore?
The recorded original offset is ET38. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.
Which vehicles have the same PCD as a Opel Commodore?
With the same PCD (5x120) and the same centre bore (69.5 mm), these include: Opel Monza A, Opel Senator A, Pontiac GTO. Offset, width and rim diameter still need checking for each vehicle.
