What does PCD mean?
PCD stands for pitch circle diameter. It is the most basic fitment criteria - if you don’t get this right then your new alloys won’t even bolt on to your car! Different vehicle manufacturers use different PCDs - they are denoted by numbers such as “4x100” and “5x114.3” - the first number refers to the number of bolts (or nuts) holding on each wheel. This is normally 4 or 5, but it can be 3 or even 6 for some vehicles. The second number refers to the diameter of the circle that these holes lie on - if you were to draw an imaginary line through all of the holes this would create a circle. If you then measured the diameter of this circle it would give you the figure you need. The good news is that you don’t really need to worry about this because our vehicle selector ensures that the wheels we are recommending for your car are the correct PCD.
