2021 Mercedes-Benz CLA — Frequently Asked Questions
What is the bolt pattern for a 2021 Mercedes-Benz CLA?
The 2021 Mercedes-Benz CLA uses a 5x112 bolt pattern (also called lug pattern or PCD). The center bore is 66.5mm and the offset is 45mm.
What other years of Mercedes-Benz CLA have the same bolt pattern as the 2021?
The Mercedes-Benz CLA uses the 5x112 pattern from 2016 through 2024. Wheels from any of these model years are dimensionally compatible with the 2021, provided the offset and center bore also match.
What does 45mm offset mean for the 2021 CLA?
An offset of 45mm means the wheel's mounting surface is 45mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Mercedes-Benz.
Can I use spacers on my 2021 Mercedes-Benz CLA?
Yes, but ensure the wheel spacers match the 5x112 bolt pattern and 66.5mm center bore. Also verify that you have enough thread engagement for your B 14x1.50 hardware.
Why is matching the 66.5mm center bore important for the 2021 CLA?
The 66.5mm 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.
What is the center bore of a 2021 Mercedes-Benz CLA?
The factory center bore (hub bore) for the 2021 Mercedes-Benz CLA is 66.5mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
Fitment Checklist Before You Buy Wheels
- 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).
