Pitch Circle Diameter:
- Pitch Circle Diameter, which is the diameter of the circle that passes through the center of the bolt holes or studs on a hub or drum.
- This is the same as the mounting holes on a wheel rim.
- If ‘S’ is the distance between two adjacent studs/bolts or holes (measured in millimeters) then the PCD would be:
- 4 studs/bolts or Holes = S / 0.7071
- 5 studs/bolts or Holes = S / 0.5878
- 6 studs/bolts or Holes = S / 0.5
Calculation:
Given:
PCD = 120 mm
For 6 studs/bolts or Holes, PCD =
⇒ 120 =
⇒ S = 120 × 0.5 = 60 mm
The center distance between two adjacent (nearest) holes is 60 mm.
