Do you know what makes your Mercedes wheels stay firmly on your car?
I often get asked about bolt patterns, and many car owners feel puzzled about this essential part.
The truth is that putting the wrong wheels on your Mercedes can cause serious problems – from poor handling to safety risks.
But don’t worry! I’ve spent years working with different Mercedes models, and I’m here to help you understand everything about bolt patterns.
In this guide, I’ll share the exact measurements you need, show you how to check your current pattern, and help you pick the right wheels for your specific Mercedes model.
Let me walk you through what makes Mercedes bolt patterns unique.
What Is the Bolt Pattern for Mercedes?
A bolt pattern refers to the arrangement of bolt holes on a wheel hub.
The bolt pattern for most Mercedes-Benz vehicles is 5×112, which means the wheel hub has five bolt holes arranged in a 112mm diameter circle.
This measurement is critical for ensuring a secure fit between the wheel and the hub.
However, some Mercedes models, like the G-Class, have a different bolt pattern, 5×130. These numbers indicate the lug count and the diameter of the bolt circle.
Proper measurement is essential not only for the aesthetics of your car but also for maintaining safety and performance.
A correct bolt pattern ensures the wheels are securely attached to the hub, minimizing the risk of instability or accidents.
Understanding Mercedes Bolt Patterns
Mercedes bolt patterns are crucial to ensure proper wheel fitment and compatibility.
Bolt patterns are a critical specification that directly impacts your vehicle’s wheels’ safety, performance, and fit.
Common Mercedes Bolt Patterns:
5×112:
- Found on most Mercedes sedans, coupes, and SUVs.
- Ensures compatibility with standard OEM wheels.
5×130:

- Check bolts for signs of wear, damage, or corrosion.
- Replace any damaged bolts to ensure proper wheel installation.
- Confirm that the hub is clean and dry before proceeding to install new wheels.
- Apply a small amount of anti-seize compound to the bolt threads to prevent seizing and ease future removal.
Step 6: Install the New Wheels
- Align the new wheel with the hub, ensuring the bolt pattern matches exactly.
- Hand-tighten the lug nuts to avoid cross-threading.
- Use a lug wrench to secure the nuts loosely before final tightening.
- Double-check the wheel alignment before proceeding further.
Step 7: Tighten the Lug Nuts in a Star Pattern
- Use a torque wrench to tighten nuts to the manufacturer’s recommended torque.
- Follow a star or crisscross pattern to distribute pressure evenly.
- For security reasons, recheck all nuts after initial tightening.
- Avoid over-tightening, which could damage the bolts or wheel.
Step 8: Lower the Vehicle and Final Check
- Carefully lower the car using the jack, ensuring smooth and controlled descent.
- Recheck lug nut torque once the vehicle is fully grounded.
- Take the car for a short drive to confirm wheel stability.
- Perform a final inspection of the wheels and bolts after the test drive.
- Listen for unusual noises or vibrations during the test drive, indicating potential issues.
- Check the alignment and balance of the wheels to ensure smooth operation.
These steps ensure a safe and secure wheel replacement, maintaining optimal performance and safety.
