PCD Calculator

PCD stands for Pitch Centre Diameter. It is the diameter of an imaginary circle going through the centre of all the studs/bolts/holes in your wheel or hub.

Finding out the PCD of your wheel or hub can be difficult, especially if there are an odd number of holes/studs, but it's important to know when fitting aftermarket wheels or spacers.

This calculator can be used to work out your PCD based on an easy measurement. See the diagram for a guide on how to measure, put your information into the fields below, and click the Calculate button.
