- R – This indicates that the tire is of radial construction, which is standard in modern tires.
- 17 or 18 – This is the diameter of the wheel in inches that the tire is designed to fit.
Why Tire Size Matters
Using the correct tire size is not just about aesthetics. It affects handling, fuel efficiency, and safety. Here are a few reasons why you should pay attention to your tire size:
- Performance: The right size ensures optimal contact with the road, improving handling and responsiveness.
- Fuel Efficiency: Incorrect tire sizes can lead to increased rolling resistance, which can negatively impact your fuel economy.
- Safety: Using the wrong tire size can lead to issues like blowouts or reduced traction, especially in wet conditions.
If you’re considering changing your tires, make sure to stick with the recommended sizes for your specific trim. It’s not just about fitting tires on your rims; it’s about keeping your BMW performing at its best.
