The Pitch Circle Diameter (PCD) is the diameter of the circle which passes through the centre of all the studs, wheel bolts or wheel rim holes.
The easiest way calculate the PCD is as follows:
- Identify the size of rim or tyre size. (This helps to narrow down the likely PCD sizes)
- Measure the distance 'S' between two adjacent studs from the centre of each hole.
- Using the calculator enter the number of studs/holes & 'S' and press 'calculate'.
- Using the relevant diagram depending on the number of studs you have you should be able to identify the correct PCD.
Note: Imperial sizes are commonly used on UK trailers whereas European trailers use metric.

How to find the Wheel Offset measurement
The wheel rim 'offset' is the distance between the centre line of the rim and the faceplate that bolts onto the hub. It is important to know as different offsets will alter the distance between the inside edge of the rim and the side of the trailer or caravan. It could also increase the overall width of the axle and it may also alter the capacity of a suspension system.
This diagram shows the dimension of the 'Offset' usually measured in millimetres.
When the centre line is the same as the mounting plate line then it has a Zero or No offset.
If the rim has an offset it is usually marked on the front of the rim, near the mounting holes, an example would be:-
- ET30 would be a 30mm offset.
- ET20 would be a 20mm offset.
Simple way to measure the wheel rim Offset
Start by placing the rim on a level surface with the front of the mounting plate facing upwards, then measure the distance 'A' (in millimetres) from the mounting plate edge to the surface.
Turn the rim over and measure the distance 'B' again as above.
Take distance B from A and divide by 2, this will give you the offset. If the result is a minus number then you have a Negative Offset. Rims with a negative offset are not usually found on trailers and caravans.
Please note: that if the rim edge is not flat on the surface when measuring B (due to the bulge in the rim) then the distance between the surface and the rim edge needs to be deducted from B before making the calculation.
