PCD
The term PCD stands for (pitch circle diameter) and is the diameter of a circle drawn through the centre of your wheels bolt holes. PCD is measured in millimetres and also indicates the number of studs or bolts the wheel will have.
One of the most common fitment has 4 studs and a PCD of 100mm, hence the fitment 4×100. Check the fitment guide above to check the fitment of your car, if you are unsure please check with vehicle and wheel manufacturer before purchase and subsequent fitment.
OFFSET
Every car requires a unique offset. This is where the outside of the wheel needs to be in relation to the bodyline of the vehicle, realistically you can go 5-7mm outside these recommendations, but always check with vehicle and wheel manufacturer’ if you are unsure, as there are often other factors that need to be considered.
