Finding the correct wheel bolt pattern for your Mercedes-Benz is crucial for safety and proper fitment. A mismatch can lead to dangerous handling and potential damage to your vehicle. This guide will help you understand Mercedes-Benz wheel bolt patterns and how to find the right one for your specific model.
What is a Wheel Bolt Pattern?
The wheel bolt pattern, also known as the PCD (Pitch Circle Diameter), refers to the diameter of the imaginary circle that passes through the centers of the wheel studs or bolts. It's expressed as a number followed by a letter, like 5x112. This means the wheel has 5 studs or bolts, and the diameter of the circle passing through their centers is 112mm. Getting this wrong is a significant safety risk.
Common Mercedes-Benz Wheel Bolt Patterns
Mercedes-Benz uses several different bolt patterns across its model range. Some of the most common include:
-
5x112: This is arguably the most common bolt pattern for many Mercedes-Benz models, spanning various classes and years. You'll find it on many C-Class, E-Class, S-Class, and even some SUVs.
-
5x120: Used on certain models, particularly some older vehicles and potentially some AMG models. Always double-check your specific model year.
-
5x130: Less prevalent than the others, this pattern might be found on older or specific Mercedes models.
Important Note: These are just some of the common patterns. There are other variations depending on the model year, specific trim level, and even optional features. It's absolutely critical to verify the correct pattern for your Mercedes-Benz.
How to Find Your Mercedes-Benz Wheel Bolt Pattern
There are several ways to determine the correct bolt pattern for your Mercedes-Benz:
-
Check your owner's manual: This is the most reliable source of information. The manual should clearly specify the wheel bolt pattern, along with other crucial wheel specifications.
-
Look at the existing wheels: The bolt pattern is usually stamped on the back of your current wheel. You may need to clean the area to see it clearly.
-
Check the VIN plate: While not always directly stated, the VIN (Vehicle Identification Number) can be used to lookup your vehicle's specifications, including the wheel bolt pattern, through online databases or your local Mercedes-Benz dealership.
-
Consult a tire professional: Tire shops and mechanics specializing in Mercedes-Benz vehicles can quickly identify your car's wheel bolt pattern.
What Else to Consider Besides Bolt Pattern
Beyond the bolt pattern, you need to consider other factors when choosing replacement wheels:
- Wheel diameter (inches): This is the overall diameter of the wheel.
- Wheel width (inches): The width of the wheel, often expressed in inches.
- Offset (ET): This measurement dictates how far the wheel's mounting surface is from the centerline. Incorrect offset can lead to rubbing issues.
- Center bore (CB): The diameter of the hole in the center of the wheel that fits over the hub.
What happens if I use the wrong bolt pattern?
Using the wrong bolt pattern is incredibly dangerous. The wheels may not mount securely, leading to wheel separation while driving, potentially resulting in a serious accident. It's not a risk worth taking; always ensure precise compatibility.

Are aftermarket wheels compatible with my Mercedes-Benz?
Many aftermarket wheels are compatible, but it is absolutely crucial to verify that they have the correct bolt pattern, offset, center bore, and diameter before purchasing them. A reputable dealer will be able to help you find the correct fit.
Can I use different wheel sizes on the same axle?
No, it's not recommended to use different wheel sizes on the same axle. This can affect your vehicle's handling and stability.
