Expert Buying Guide for 2018 Mercedes-Benz C-Class
For your 2018 Mercedes-Benz C-Class, the 5x112 bolt pattern and 66.5mm center bore are critical. Aftermarket wheels often have a larger center bore (e.g., 73.1mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The factory offset is 48mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (14x1.50) and seat type—Mercedes typically uses ball seats, but aftermarket wheels may require conical or flat seats. Mismatched lug nuts can lead to wheel loosening. Verify lug nut engagement and torque to 110 Nm (81 lb-ft) after 50 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50 miles of driving to ensure proper seating.
- ✅ Avoid using universal fit wheels without hub-centric rings; they can cause vibration and stress on wheel bearings.
- ✅ Check brake caliper clearance when changing offset or wheel diameter; 18-inch wheels are the minimum for most C-Class trims.
- ⚠️ 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).
