Pitch Circle Diameter

What is Pitch Circle Diameter or PCD?

The term PCD (pitch circle diameter) is often used when specifying the correct wheel trims or wheel nut safety products to fit a certain spacing of wheel nuts.

The pitch circle diameter is simply the distance in mm from the centre of any one wheel nut across the middle of the wheel to the centre of the opposite wheel nut.

The PCD measurement is NOT the space between the nuts.
