Find Your Stud Pattern

 

How to identify which wheel/rim suits your trailer hubs:

Stud patterns vary from hub to hub and with our quick and easy guide, we will give you the best methods of identifying your stud pattern, or PCD (Pitch Circle Diameter) to save you time and a lot of headaches when buying your new trailer wheels.

Most commonly, you will find your hub will have either 4, 5, or 6 studs and measuring your PCD will vary depending on how many studs it has.

If you have an odd number of studs you must measure from the centre of one stud, to the furthest edge of the opposite stud.

For an even stud pattern (4 or 6 studs) You can simply measure from the centre of one stud to the centre of the opposite stud.

Once you have this precise measurement, you can use our quick guide (below) to determine which stud pattern you have so you can ensure you can find the right parts to suit your particular hub.
