The bolt pattern on the 2019 Audi A4 is 5x112 (five lug holes on a 112 mm circle).
This is the standard wheel-mounting interface for most Audi models in the B9 generation. In addition to the bolt pattern, other fittings like the center bore and lug hardware matter for wheel compatibility and proper centering.
Bolt pattern specifications
Key measurements used when identifying compatible wheels and adapters:
- Bolt pattern: 5x112 mm (five lugs on a 112 mm bolt circle).
- Center bore: 66.6 mm (hub-centric design on many factory wheels).
- Lug hardware: M14 x 1.5 lug bolts with a 60-degree (conical) seat.
- Hub-centric design: factory wheels center on a 66.6 mm bore; aftermarket wheels may require hub-centric rings if the bore differs.
In practical terms, when shopping for wheels for a 2019 A4, aim for a 5x112 pattern with a 66.6 mm center bore, and verify that the lug bolts and seat type match your wheel purchase. If the wheel bore is larger than 66.6 mm, use hub-centric rings to ensure proper centering and balance.
Additional notes for owners and shoppers
Market variations and verification
Most 2019 A4 configurations (including common sedan models) share the same bolt pattern and center bore. However, if you are purchasing wheels in a non-US market or for a special edition, always confirm the exact specs with the vehicle VIN or official documentation to avoid fitment issues.
Summary
The 2019 Audi A4 uses a 5x112 bolt pattern with a 66.6 mm center bore and lug bolts sized M14 x 1.5 with a 60-degree conical seat. When selecting wheels, ensure these specifications are matched, and consider hub-centric rings if the wheel bore differs from 66.6 mm to maintain proper centering and safe operation.
