Expert Buying Guide for 2015 Audi S4
For your 2015 Audi S4, the bolt pattern is 5x112 with a center bore of 66.6mm. Aftermarket wheels often have a larger bore, so hub-centric rings are essential to prevent vibration and ensure proper load distribution. The offset is critical: stock is around 45mm, but you can vary within ±5mm for most setups; going too low (e.g., 35mm) may cause rubbing, while too high (e.g., 50mm) can lead to brake caliper clearance issues. Always use lug nuts with the correct thread pitch (14x1.5) and seat type—Audi typically uses ball seats, but aftermarket wheels may require conical (60-degree) or ball seats. Never mix seat types, as this can cause wheel loosening. Re-torque after 50-100 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 90 ft-lbs after 50-100 miles of driving.
- ✅ If using aftermarket wheels, verify that the center bore is at least 66.6mm; use hub-centric rings if larger.
- ✅ Check brake caliper clearance when changing offset; some 19x8.5 ET35 wheels may require spacers or caliper grinding.
- ⚠️ 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).
