Expert Buying Guide for 2018 Mercedes-Benz GLS
For your 2018 Mercedes-Benz GLS, the 5x112 bolt pattern and 66.5mm center bore are critical. Aftermarket wheels often have a larger center bore (e.g., 66.6mm or 73.1mm), requiring hub-centric rings to prevent vibration and ensure proper load distribution. The factory offset is around 55mm; 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 shank-style nuts. Never reuse old lug nuts; torque to manufacturer specs (typically 110-130 Nm) and re-torque after 50-100 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles to ensure proper seating.
- ✅ Verify wheel hub bore matches; if not, use hub-centric rings (66.5mm ID).
- ✅ Check offset carefully; 55mm is ideal, but 50-60mm may work with testing.
- ⚠️ 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).
