2017 BMW M3 Tire Size Overview

The 2017 BMW M3 is a high-performance sports sedan that combines luxury and power. One of the key components that contribute to its performance is the tire size. Understanding the tire specifications for different trims of the M3 can help you make informed decisions about replacements and upgrades. Let’s dive into the details.

Tire Size by Trim

The 2017 BMW M3 comes in several trims, each with specific tire sizes that cater to performance and handling. Here’s a breakdown of the standard tire sizes for each trim:

• Standard M3
• Front: 255/40R18
• Rear: 275/40R18
• M3 Competition Package
• Front: 255/35R19
• Rear: 275/35R19

Understanding Tire Sizes

Tire sizes are represented in a format that provides critical information. For instance, in the size 255/40R18:

• 255: This number indicates the tire’s width in millimeters.
• 40: This is the aspect ratio, which is the height of the sidewall as a percentage of the width. A lower number means a shorter sidewall, which usually translates to better handling.
• R: This indicates that the tire is of radial construction.
• 18: This is the diameter of the wheel in inches that the tire is designed to fit.

Performance Implications

Choosing the right tire size is crucial for maintaining the performance characteristics of your M3. Here’s why:

• Handling: A wider tire provides better grip, especially during cornering. The M3’s tire sizes are designed to optimize handling and stability.
• Ride Comfort: The aspect ratio affects ride quality. Lower profile tires (like those on the Competition Package) may offer a stiffer ride but improve responsiveness.
• Speedometer Accuracy: Changing tire sizes can affect the accuracy of your speedometer. Stick to the recommended sizes to ensure your speed readings are correct.
