Calculating Pcd

[Duncan]

Yes sure it would be easy if it was a 4 stud wheel....but it is 5 stud.

I have measure the distance between 2 near studs and 2 away studs, 63mm and 100mm respectively.

So the question is, how do I calculate the PCD from these measurements?

HELP!

You calculate it by measuring betwwen two adjoining studs/holes and multiplying the figure by 1.7012

hole centres must be used when measuring....hope this helps

ah hah! which gives me 108.8 which is what i thought a bodgy old Torana wheel.

Where does 1.7012 from? I failed maths.

rofl once apon a time there was a tyre fitter that knew trig...ever since then everyone has used that number.

Thanks

1.7012 should actually be 1.7013 but whos here to argue

proof is attached
