Expert Buying Guide for 2004 Mercedes-Benz CLK-Class
For your 2004 Mercedes-Benz CLK-Class, the 5x112 bolt pattern and 66.6mm center bore are critical. Aftermarket wheels often have a larger center bore (e.g., 73.1mm), requiring hub-centric rings to prevent vibrations and ensure proper load transfer. The offset is sensitive; the factory spec is 37mm, but a range of 30-45mm is acceptable depending on width. Deviating too far can cause rubbing or clearance issues. Always use the correct lug nuts: B 12x1.50 thread pitch with a ball seat (Mercedes-specific). Using conical seat lug nuts can damage the wheel. Re-torque after 50-100 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 110 Nm (81 lb-ft) after 50-100 miles, then periodically check.
- ✅ Avoid using wheels from non-Mercedes vehicles without verifying center bore and offset; hub-centric rings are mandatory if bore >66.6mm.
- ✅ Inspect for clearance between the wheel spokes and brake calipers, especially with aftermarket wheels; the CLK's calipers can be large.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- ⚠️ Confirm bolt pattern carefully. 5x112 is often confused with other common 5-lug patterns.
- ⚠️ Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).

2004 Mercedes-Benz CLK-Class — Frequently Asked Questions
What is the bolt pattern for a 2004 Mercedes-Benz CLK-Class?
The 2004 Mercedes-Benz CLK-Class uses a 5x112 bolt pattern (also called lug pattern or PCD). The center bore is 66.6mm and the offset is 37mm.
What other years of Mercedes-Benz CLK-Class have the same bolt pattern as the 2004?
The Mercedes-Benz CLK-Class uses the 5x112 pattern from 1998 through 2009. Wheels from any of these model years are dimensionally compatible with the 2004, provided the offset and center bore also match.
Why is matching the 66.6mm center bore important for the 2004 CLK-Class?
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.
Do 2004 Mercedes-Benz CLK-Classs use lug bolts or lug nuts?
The 2004 CLK-Class requires B 12x1.50 hardware. Check your specific trim to ensure you use the correct conical or spherical seating.
How do I measure the bolt pattern on my 2004 Mercedes-Benz?
The 2004 CLK-Class 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 2004 Mercedes-Benz CLK-Class?
Refer to your owner's manual for exact specs, but always tighten the B 12x1.50 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
