Wheel Bolt Patterns vs. Wheel Center Bore
Comparing 2 standards across 14 specifications. 14 key differences identified.
Wheel Bolt Patterns (defined by the number of wheel lugs and their Pitch Circle Diameter / PCD in millimeters or inches, e.g. 5×114.3 mm or 5×4.5") establish the mechanical bolt hole circle on the wheel hub. Standardizing automotive fitments across Japanese (5×114.3), German VAG/Mercedes (5×112), BMW (5×120 / 5×112), Ford/PSA (4×108), and pickup trucks (6×139.7 / 6×5.5").
The Wheel Center Bore (measured in millimeters to 0.1 mm precision) is the machined center opening on the back of a wheel designed to fit snugly over the vehicle's raised wheel hub snout. Ensuring the wheel is mounted 'hub-centrically' (bearing vehicle weight on the center hub collar rather than the lug bolts), preventing high-speed vibrations.
