Fitting wheels on a Ford Thunderbird

A Ford Thunderbird (1973–1978) uses a 5x127 or 5x108 PCD and a centre bore of 78.1 or 63.4 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

PCD: 5x127 or 5x108 required. See all vehicles with 5x127.
Centre bore: the wheel must have a centre bore of 78.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 78.1 mm.
Offset: the original is ET39. 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 Ecrous - 1/2 - 20 UN. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
