Expert Buying Guide for 2018 Mercedes-Benz CLA
For the 2018 Mercedes-Benz CLA, the critical fitment specs are a 5x112 bolt pattern, 66.5mm center bore, and 49mm offset. When selecting aftermarket wheels, ensure the center bore matches exactly or use hub-centric rings to prevent vibration and ensure proper load distribution. The offset is sensitive; deviations beyond ±5mm may cause rubbing or clearance issues with brakes and suspension. Always verify lug nut compatibility: the CLA uses B 14x1.50 thread pitch with a ball seat. Using incorrect lug nuts (e.g., conical seat) can lead to wheel loosening. Cross-compatible wheels from 2016–2024 CLA models fit directly. Prioritize safety over aesthetics.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50 miles of driving to account for settling.
- ✅ Avoid using universal fit wheels without hub-centric rings; they can cause steering wheel vibration.
- ✅ Check brake caliper clearance when using wheels with offset below 44mm or above 54mm.
- ⚠️ 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).

2018 Mercedes-Benz CLA — Frequently Asked Questions
What is the bolt pattern for a 2018 Mercedes-Benz CLA?
The 2018 Mercedes-Benz CLA uses a 5x112 bolt pattern (also called lug pattern or PCD). The center bore is 66.5mm and the offset is 49mm.
What other years of Mercedes-Benz CLA have the same bolt pattern as the 2018?
The Mercedes-Benz CLA uses the 5x112 pattern from 2016 through 2024. Wheels from any of these model years are dimensionally compatible with the 2018, provided the offset and center bore also match.
Why is matching the 66.5mm center bore important for the 2018 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.
Will wheels from another Mercedes-Benz fit my 2018 CLA?
Only if they share the exact same 5x112 bolt pattern, a compatible offset, and a center bore equal to or larger than 66.5mm.
How do I measure the bolt pattern on my 2018 Mercedes-Benz?
The 2018 CLA uses a 5x112 pattern. For 4, 6, or 8-lug wheels, measure center-to-center across opposite holes. For 5-lug, measure from the center of one hole to the back of the opposite hole.
How tight should I torque the lug nuts on a 2018 Mercedes-Benz CLA?
Refer to your owner's manual for exact specs, but always tighten the B 14x1.50 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
