Expert Buying Guide for 2006 Audi A4
For your 2006 Audi A4, the 5x112 bolt pattern is shared across 1996–2024 models, ensuring broad compatibility. However, the 57.1mm center bore is critical: aftermarket wheels often have larger bores, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset is sensitive; stock is 45mm, but deviations beyond ±5mm may cause rubbing or clearance issues. Always verify offset with test fitting. Lug nuts must be 14x1.50 with a ball seat (R13 ball radius). Using incorrect taper (e.g., cone seat) can lead to wheel loosening. Re-torque after 50–100 miles. Avoid spacers unless hub-centric and properly sized.

Quick Tips & Safety Warnings
- ✅ Always use hub-centric rings if aftermarket wheels have a bore larger than 57.1mm to prevent vibration and ensure centering.
- ✅ Re-torque lug nuts to 90 ft-lb after 50–100 miles of driving to account for settling.
- ✅ Verify wheel offset with a test fit; offsets outside 40–50mm may cause rubbing on suspension or fenders.
- ⚠️ 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).
