PCD (Pitch Circle Diameter) in alloy wheels refers to the diameter of an imaginary circle drawn through the centre of the wheel’s bolt holes. It is a crucial specification when choosing or replacing wheels, as it ensures compatibility with the vehicle’s hub. Here at ALLOYHUB we ensure that the wheels supplied are the correct PCD and fitment for your vehicle.
Key Components of PCD:
- Number of Bolt Holes – the number of holes for the wheel bolts or studs (e.g., 4, 5, 6).
- Diameter of Circle – the diameter of the circle (in millimetres) that passes through the centre of the bolt holes.
For example, a PCD of 5×114.3 means:
- 5 bolt holes
- 114.3: Diameter (in mm) of the circle passing through the centre of these bolt holes.
Many people believe that alloy wheels are one size fits all; unfortunately, this is not the case. Just because you purchase a set of branded ‘Audi’ wheels for example doesn’t mean they will fit your Audi as there any many things to consider from PCD, to Offset, Wheel Width, Centre Bore, and overall wheel size. We will touch on the other considerations in other blog posts coming shortly from ALLOYHUB.
