Fitting wheels on a Pontiac Catalina

A Pontiac Catalina (1971–1976) uses a 5x127 or 5x120.65 PCD and a centre bore of 78.1 or 70.3 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

  • PCD: 5x127 or 5x120.65 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.
  • Fixings: thread Ecrous - 1/2 - 20 UN. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
  • Tyres: original fitment is 215/75R15, 205/75R15. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).
