How to Take Your Wheel Offset Measurements

Because some of the more classic vehicles have had modifications made to them, different hubs, brake discs fitted instead of the original brake drums, the vehicle has been lowered etc, we will always ask you for two measurements, poke and inset.

“Poke” is the measurement from the flange hub face surface out towards your outer wheel arch or wherever you would like the outer wheel rim to finish and “inset” is the measurement from the flange hub face surface in towards your suspension, these measurements are sometimes known as the front and back wheel space. These measurements are really important and let us know what wheel offset you need, if you get this wrong your wheels may fit incorrectly or rub but we are here to help you, just phone us if you are unsure and we can guide you through this.

The wheel measurement sheet below will enable you to give us all the information we need from your car to ensure we get the wheel measurements right for you, if you are unsure please call us or simply send us an e-mail and we will be able to help you, it's better to spend 5 mins on the phone then getting it wrong and having to return them.

How to measure your PCD

If it's a four stud hub, it's really easy, the quick way is to pick a stud and call it number one stud then measure from the inside of that stud diagonally across to the outside of number three stud, do this measurement in millimetres as it's more accurate.

If you have a five stud hub you need to measure from the centre of number one stud to the centre of number two stud then multiply (times) that by 1.7012 which will give you your 5 stud PCD there again do this measurement in millimetres as it's more accurate.
