Expert Buying Guide for 2004 Mercedes-Benz SLK-Class
For your 2004 Mercedes-Benz SLK-Class, the 5x112 bolt pattern and 66.6mm center bore are critical. Aftermarket wheels must have a bore ≥66.6mm; use hub-centric rings to prevent vibration. Offset range is 30-50mm; staying within 35-45mm ensures proper clearance. Always use lug nuts with 14x1.5 thread pitch and correct seat type—Mercedes typically uses ball seats, but verify. Avoid conical seat lug nuts as they can damage wheels. Torque to 110-130 Nm and re-torque after 50 miles. Cross-compatible with 1998-2015 SLK-Class wheels.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50 miles of driving to ensure proper seating.
- ✅ Avoid wheels with offset below 30mm or above 50mm to prevent rubbing or clearance issues.
- ✅ Verify lug nut seat type (ball vs. conical) before installation; Mercedes uses ball seats.
- ⚠️ 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).
