Where is PCD messured from?

Featured Replies

As title says really, I have a set of wellers which i did not know the PCD on, I have messured them and from the centre of the hole they are 75mm which i think is a bit odd but from the edge it is 95mm which i find more beliveable rather than 75mm.

So could anyone help me out? i am not really into wheels, as long as they fit and they arent bent i dont care about them but would just like to know!

Thanks a lot, Tomm

from the centre of the bolt hole easy on 4 stud as the holes are opposite each other

ah right thought so, but 75 mm seemed way to small?

what has a 75mm PCD then? 2000 106's ect?

Nothing has a PCD Of 75, (Well not that i know of) Thought smallest was 98 and thats on a Punto,

106's/Saxo's are 108,

Measure opposite holes, not adjacent.

Imagine a circle drawn through the centre of all the holes. It's the diameter of that circle.

edge to edge is the same as middle to middle.

amazing how many people wave a ruler to try and guess where the middle is

This diagram should clear up any inconsistancies in how you measure pcd (pitch circle diameter).
