To understand how our system works we first have to answer the question of what PCD is and why would it need to be converted.
- PCD or Pitch Circle Diameter is the distance between the mounting holes on a vehicle's wheel or hub, in a circle. For example 5 x 112. (5) refers to the number of individual lug holes, or studs. (112) is the distance, in millimeters, apart from each other in a circle in which the studs or lug holes are spaced. A PCD conversion is necessary when the lug holes on a given set of wheels do not match the vehicle hub's PCD.
- Our conversion works by simply offsetting the variance, allowing our PCD variable washer to seat itself center on the lug hole, while the nut shifts its center point to the stud.
