Let's dive into everything you need to know about getting the perfect fit for your ride.

Understanding Wheel Size Specifications

When we talk about wheel size, we're usually referring to a set of numbers and letters that describe the wheel's dimensions. These specs typically look something like this: 17x8.5J ET30 5x112. Let's break down what each of these components means so you can make an informed decision for your 2016 Mercedes E-Class.

• Diameter: The first number, in this case, '17', represents the diameter of the wheel in inches. This is the measurement across the wheel from one end to the other through the center. For the 2016 E-Class, different trims and packages might come with varying wheel diameters, commonly ranging from 17 to 19 inches. Knowing the correct diameter is crucial because it directly affects the tire size you can use.
• Width: The second number, '8.5', indicates the width of the wheel, also measured in inches. This refers to the distance between the inner and outer flanges of the wheel. The width affects the tire's profile and how it sits on the wheel. A wider wheel can accommodate a wider tire, which can improve grip and handling, but it might also affect fuel economy and ride comfort.
• Flange Type: The letter 'J' specifies the flange type of the wheel. The flange is the part of the wheel that the tire sits on. 'J' is a common flange type, but there are others, like 'B', 'D', and 'K'. The flange type needs to match the tire for a secure fit. While 'J' is standard, always double-check to ensure compatibility.
• Offset (ET): 'ET30' refers to the wheel offset, measured in millimeters. Offset is the distance between the wheel's mounting surface and its centerline. A positive offset (like ET30) means the mounting surface is further out from the centerline, while a negative offset means it's closer to the inside. Offset affects how the wheel sits in the wheel well and can impact suspension and brake clearance. Getting the correct offset is vital to prevent rubbing or other fitment issues.
• Bolt Pattern: '5x112' is the bolt pattern, indicating the number of bolts and the diameter of the bolt circle in millimeters. In this case, '5' means there are five bolts, and '112' means the diameter of the circle that passes through the center of each bolt hole is 112mm. The bolt pattern must match the vehicle's hub for the wheel to be properly mounted. The 2016 Mercedes E-Class typically uses a 5x112 bolt pattern, but it's always a good idea to verify.

Understanding these specifications will help you choose the right wheels for your 2016 Mercedes E-Class, ensuring they fit properly and perform as expected. If you're unsure, consulting with a tire or wheel professional can provide additional guidance and ensure you get the perfect match for your vehicle.

Plus Sizing and Upsizing Your Wheels

So, you're thinking about plus sizing or upsizing your wheels on your 2016 Mercedes E-Class? This is a pretty common upgrade, and it can definitely give your car a fresh, new look and potentially improve handling. Plus sizing involves increasing the wheel diameter while decreasing the tire's sidewall height to maintain the same overall rolling diameter. This keeps your speedometer accurate and avoids any rubbing issues. Here’s what you should consider:

• Benefits of Upsizing: One of the main reasons people upsize their wheels is for aesthetic appeal. Larger wheels with lower profile tires can give your E-Class a sportier, more aggressive stance. Additionally, upsizing can improve handling and cornering, as the shorter sidewalls reduce tire flex. This can result in more precise steering and better responsiveness.
• Considerations Before Upsizing: Before you jump into upsizing, there are a few things you need to keep in mind. First, ride comfort can be affected. Lower profile tires have less cushioning, which can make the ride feel harsher, especially on rough roads. Also, larger wheels and tires can be heavier, which can slightly reduce fuel economy and acceleration. It’s crucial to strike a balance between aesthetics, performance, and comfort.
• How to Plus Size Correctly: The key to successful plus sizing is maintaining the original rolling diameter. This means that as you increase the wheel diameter, you need to decrease the tire's sidewall height. For example, if your E-Class originally came with 17-inch wheels and 245/45R17 tires, you might consider upsizing to 18-inch wheels with 245/40R18 tires or 19-inch wheels with 245/35R19 tires. These combinations will keep the rolling diameter close to the original, ensuring proper speedometer readings and avoiding clearance issues.
• Checking for Clearance: Before making any changes, always check for clearance. Make sure the new wheels and tires won't rub against the fenders, suspension components, or brake calipers. Use a tire size calculator to compare the dimensions of the new tires with your original tires. It’s also a good idea to test fit the new wheels and tires before fully committing to the purchase. You can turn the steering wheel lock to lock and check for any signs of rubbing.
• Professional Advice: If you're unsure about any aspect of plus sizing, it’s always a good idea to consult with a tire and wheel professional. They can provide expert advice and ensure that you choose the right size wheels and tires for your 2016 Mercedes E-Class. They can also help with installation and ensure that everything is properly aligned.
