Expert Buying Guide for 2009 Audi A4
For your 2009 Audi A4, the 5x112 bolt pattern is shared with all A4 models from 1996–2024. However, critical fitment details include a 57.1mm center bore—aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibrations. The offset is sensitive: stock is 45mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut thread pitch (14x1.50) and seat type: Audi uses ball seats, not conical. Using incorrect lug nuts can lead to wheel loosening. For safety, re-torque after 50–100 miles and inspect for proper seating.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 90 ft-lb after 50–100 miles of driving.
- ✅ If using aftermarket wheels, ensure hub-centric rings match the 57.1mm bore to avoid vibrations.
- ✅ Avoid spacers thicker than 5mm without extended studs; verify offset remains within 40–50mm range.
- ⚠️ Confirm bolt pattern carefully. 5x112 is often confused with other common 5-lug patterns.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).
