Wheel PCD (Pitch Circle Diameter)

Cortina MK1 has a PCD of 4 x 108 = 4 stud, 108 mm between each stud converted to imperial is 4 x 4.25 inch. The below table lists cars that have the same PCD as MK1 Cortina, but keep in mind that offset and centre bore etc will render many of these wheels unsuitable to bold straight onto your Cortina.
