Understanding Tire Specifications

To make informed decisions about tire replacements or upgrades, it’s essential to understand what these numbers mean:

• 255/40 R18: The first number (255) indicates the tire width in millimeters. The second number (40) is the aspect ratio, which is the height of the sidewall as a percentage of the width. The ‘R’ signifies that it’s a radial tire, and the last number (18) is the diameter of the wheel in inches.
• 265/35 R19: Similar breakdown as above, but with a wider tire and a lower sidewall height, which can improve handling but may sacrifice some ride comfort.

Tire Performance Considerations

Choosing the right tire size is not just about fitting the wheel wells. It affects various performance aspects of your M4, including:

• Handling: Wider tires provide better grip, especially during cornering.
• Ride Quality: Tires with a lower aspect ratio can lead to a stiffer ride.
• Speedometer Accuracy: Using the correct tire size ensures your speedometer reads accurately.
