Expert Buying Guide for 2009 Audi S4
The 2009 Audi S4 uses a 5x112 bolt pattern with a 57.1mm center bore. When selecting aftermarket wheels, hub-centric rings are mandatory to ensure proper load distribution and prevent vibrations. The factory offset is 45mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut compatibility: the thread pitch is 14x1.50, and the seat type must match (factory uses ball seat). Using incorrect lug nuts can lead to wheel detachment. For optimal safety, choose wheels with a load rating exceeding the vehicle's gross weight.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to maintain clamping force.
- ✅ Avoid wheels with offset below 35mm on lowered suspensions to prevent fender rubbing.
- ✅ Always use hub-centric rings for aftermarket wheels; plastic rings are acceptable for street use.
- ⚠️ 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).
