Expert Buying Guide for 2018 Audi S4
For the 2018 Audi S4, the 5x112 bolt pattern and 66.5mm center bore are critical. Aftermarket wheels require hub-centric rings to avoid vibration. Offset must stay within 30-45mm; deviations risk rubbing or brake clearance issues. Always use 14x1.5 lug nuts with the correct seat type—Audi typically uses ball seats, but aftermarket wheels may require conical (60-degree) seats. Verify compatibility to prevent loosening. Cross-compatible with 1992–2024 Audi S4 wheels, but always test fitment.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to ensure proper seating.
- ✅ Avoid using universal lug nuts; they may not seat correctly with Audi's ball-seat or aftermarket conical-seat wheels.
- ✅ Check brake caliper clearance when using wheels with offset near 30mm, as the S4 has large brakes.
- ⚠️ Confirm bolt pattern carefully. 5x112 is often confused with other common 5-lug patterns.
- ⚠️ This fitment uses a wide offset range. Check brake clearance and fender clearance before buying wheels.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).
