Fitting wheels on a Cadillac Fleetwood Brougham

A Cadillac Fleetwood Brougham (1977–1986) uses a 5x127 PCD and a centre bore of 78.1 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

  • PCD: 5x127 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 ET15. 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 - 7/16 - 20 U. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
  • Tyres: original fitment is 215/75R15. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).
