Understanding Tire Size Designations
When looking at tire sizes, it’s essential to understand what those numbers mean. Here’s a breakdown:
- 225: This number represents the width of the tire in millimeters.
- 50 or 45: This is the aspect ratio, indicating the height of the tire’s sidewall as a percentage of the width. A lower number means a shorter sidewall, which can improve handling but may compromise ride comfort.
- R: This indicates that the tire is of radial construction.
- 18 or 19: This is the diameter of the wheel the tire is designed to fit, measured in inches.
Understanding these specifications will help you choose the right tires for your 2015 BMW 428i Gran Coupe, ensuring optimal performance and safety on the road. Remember, sticking to the recommended tire sizes is crucial for maintaining the vehicle’s handling characteristics and ride quality.
