What is PCD?

PCD stands for Pitch Circle Diamter and is a measure of the wheel stud/bolt hole locations.  The PCD is a circle with its centre at the centre of the face of the wheel.  The centres of the mounting holes are equally spaced around this circle.  So for example a 4x130mm PCD means four mounting holes, equally spaced around a 130mm diamter circle from the centre of the wheel.

Orignal PCD measurements:

• Pre 1967 Beetle (wide 5) = 5×205 PCD
• 1968 Onwards Beetle (4 stud) = 4×130 PCD
• Splitscreen Bus (wide 5) = 5x205PCD
• Baywindow Bus 1968 to 1970 (wide 5) = 5×205 PCD
• Baywindow Bus 1971 to 1979 (Small 5) = 5×112 PCD
• Type 25 Buses 1979 to 1992 (Small 5) = 5×112 PCD
• Porsche Hubs (5 Stud) = 5×130 PCD

NOTE: Karmann Ghia`s and Type 3 Variants use the same stud patterns as the VW Beetle.

What is the offset of a wheel?

The offset is the distance from the mounting face of the wheel (where it mounts against the wheel hub), and the centreline of the wheel`s width.  It will be expressed as a distance, usually in mm and called ET.
