It’s not the centre cap hole, it’s the hole that fits over the hub :?
Rob
It’s the diameter of the bolt holes :thumbsup:
It can’t be that, 120mm? The bolt holes are much smaller than that measurement :?

5 x 120 means 5 bolt holes measuring 120mm hole to hole / probably better explained here https://www.linkedin.com/pulse/how-meas ... arrol-yang

It’s amazing how something written can be read completely differently to the way it was intended!

If you were to draw a circle connecting the bolt holes up the diameter of that circle would be 120mm!

Hope that makes sense!

As SteveSmith said....
The Pitch Circle Diameter (PCD) is the diameter of the imaginary circular line which passes through the centre of all the studs, wheel bolts or wheel fixing holes.

Personally, I would give a vote for the BBS CH-R wheels....love the look of them on stuartinzg's car..

The diameter across the centre of the bolt holes
So make a circle that dissects the bolt hole centres and it will be 120mm
