Expert Buying Guide for 2009 Mercedes-Benz GL-Class
For your 2009 Mercedes-Benz GL-Class, the correct bolt pattern is 5x112 with a center bore of 66.6mm. When selecting aftermarket wheels, ensure they have a center bore of at least 66.6mm; if larger, use hub-centric rings to prevent vibrations and ensure proper load distribution. The factory offset is 55mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut compatibility: your vehicle requires 14x1.50 thread pitch with ball seat (R14) lug nuts. Using incorrect seat type (e.g., conical) can lead to wheel loosening. For safety, re-torque lug nuts after 50-100 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 110-130 Nm after 50-100 miles, then periodically check.
- ✅ Avoid using wheels with a center bore smaller than 66.6mm; they won't fit over the hub.
- ✅ When using aftermarket wheels, always install hub-centric rings to match the 66.6mm hub bore.
- ⚠️ 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).
