Expert Buying Guide for 1999 Mercedes-Benz CLK-Class
For your 1999 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 vibration and ensure proper load transfer. The factory offset is 37mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut thread pitch (12x1.5) and seat type—Mercedes uses ball seats, not conical. Using incorrect lug nuts can lead to wheel loosening. For safety, re-torque after 50-100 miles. Cross-compatible wheels from 1998-2009 CLK-Class models fit directly.

Quick Tips & Safety Warnings
- ✅ Always use hub-centric rings if aftermarket wheels have a larger center bore than 66.6mm to avoid vibrations.
- ✅ Stick to offsets between 32-42mm to prevent rubbing on fenders or suspension components.
- ✅ Re-torque lug nuts to 110-130 Nm after 50-100 miles; use ball-seat lug nuts only.
- ⚠️ 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).

1999 Mercedes-Benz CLK-Class — Frequently Asked Questions
What is the bolt pattern for a 1999 Mercedes-Benz CLK-Class?
The 1999 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 1999?
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 1999, provided the offset and center bore also match.
How do I measure the bolt pattern on my 1999 Mercedes-Benz?
The 1999 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.
Why is matching the 66.6mm center bore important for the 1999 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.
Can I put aftermarket wheels on my 1999 Mercedes-Benz CLK-Class?
Absolutely. Just ensure the aftermarket wheels have a 5x112 bolt pattern, an offset near 37mm, and a center bore of at least 66.6mm (using hub rings if larger).
Do 1999 Mercedes-Benz CLK-Classs use lug bolts or lug nuts?
The 1999 CLK-Class requires B 12x1.50 hardware. Check your specific trim to ensure you use the correct conical or spherical seating.
