Here’s a simplified version of the P.C.D. calculation process for sharing on your social channel:
To find the Pitch Circle Diameter (P.C.D.) of wheels or hubs:
- Three Stud: Measure the distance between two adjacent holes and multiply by 1.154.
- Four or Six Stud: Measure from the inside of one hole directly across to the outside of the hole opposite.
- Five Stud: Measure from the inside of one hole to the outside of the next and multiply by 1.7012.
