A Oldsmobile Omega (1968–1978) uses a 5x120.65 PCD and a centre bore of 70.3 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 70.3 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 70.3 mm.
Fixings: thread -. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
