2020 Mercedes-Benz GLB — Frequently Asked Questions
What is the bolt pattern for a 2020 Mercedes-Benz GLB?
The 2020 Mercedes-Benz GLB uses a 5x112 bolt pattern (also called lug pattern or PCD). The center bore is 66.6mm and the offset is 30-50mm.
What other years of Mercedes-Benz GLB have the same bolt pattern as the 2020?
The Mercedes-Benz GLB uses the 5x112 pattern from 2020 through 2024. Wheels from any of these model years are dimensionally compatible with the 2020, provided the offset and center bore also match.
How tight should I torque the lug nuts on a 2020 Mercedes-Benz GLB?
Refer to your owner's manual for exact specs, but always tighten the 14x1.5 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
What is the PCD for a 2020 Mercedes-Benz GLB?
PCD stands for Pitch Circle Diameter, which is the same as the bolt pattern. For the 2020 GLB, the PCD is 5x112.
Will wheels from another Mercedes-Benz fit my 2020 GLB?
Only if they share the exact same 5x112 bolt pattern, a compatible offset, and a center bore equal to or larger than 66.6mm.
Why is matching the 66.6mm center bore important for the 2020 GLB?
The 66.6mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
Fitment Checklist Before You Buy Wheels
- 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).
