The 2017 BMW X5 M is a high-performance luxury SUV that combines power, comfort, and style. One of the critical components that contribute to its performance is the tire size. Choosing the right tires is essential for maintaining the vehicle’s handling characteristics and ensuring a smooth ride. Let’s break down the tire sizes for different trims of the 2017 BMW X5 M.
Stock Tire Sizes by Trim
The 2017 BMW X5 M comes with several trim options, but the tire sizes are generally consistent across the board. Here’s a detailed look at the stock tire sizes:
| Trim Level | Front Tire Size | Rear Tire Size |
|---|---|---|
| X5 M Base | 275/40R20 | 315/35R20 |
| X5 M Competition | 275/40R20 | 315/35R20 |
Front Tire Size
For both the base and competition trims, the front tire size is 275/40R20. This size is designed to provide excellent grip and stability, especially during high-speed maneuvers. Here’s what each number means:
- 275 – This is the width of the tire in millimeters.
- 40 – This number represents the aspect ratio, which is the height of the sidewall as a percentage of the width. In this case, the sidewall height is 40% of 275 mm.
- R20 – This indicates that the tire is radial and fits a 20-inch wheel.
Rear Tire Size
The rear tire size for both trims is 315/35R20. This wider tire provides improved traction and stability, particularly during acceleration. The breakdown is as follows:
- 315 – The width of the rear tire in millimeters.
- 35 – The aspect ratio, meaning the sidewall height is 35% of 315 mm.
- R20 – Again, this tire is radial and fits a 20-inch wheel.
Why Tire Size Matters
Choosing the correct tire size is not just about aesthetics; it’s crucial for several reasons:
- Handling: The right tire size ensures optimal contact with the road, improving cornering and stability.
- Performance: Larger tires can enhance acceleration and braking performance, which is vital for a high-performance vehicle like the X5 M.
- Safety: Properly sized tires contribute to better traction, especially in adverse weather conditions.
Aftermarket Options
If you’re considering changing your tires, there are aftermarket options available. However, ensure that any new tires match the specifications of the original sizes to maintain performance and safety. Consult with a tire professional to find the best options for your driving style and needs.
In summary, the tire sizes for the 2017 BMW X5 M are designed to maximize performance and handling. Whether you have the base model or the competition trim, understanding these specifications will help you make informed decisions about tire maintenance and replacements.
Choosing the Right Tire Sizes for Your 2017 BMW X5 M
When it comes to the 2017 BMW X5 M, selecting the right tire size isn’t just a matter of aesthetics; it’s crucial for performance, handling, and safety. Whether you’re looking for the smallest or largest tire options, understanding the implications of your choices can make a significant difference in your driving experience.
Smallest Tire Size
The stock tire size for the front of the 2017 BMW X5 M is 275/40R20. While this is the standard size, some owners have explored smaller options for various reasons, including ride comfort and cost. However, going smaller can have its drawbacks.
- Handling: Smaller tires can reduce grip and stability, especially during high-speed cornering.
- Speedometer Calibration: Changing tire sizes can affect your speedometer’s accuracy, leading to potential legal issues.
- Load Rating: Smaller tires may not support the weight of the X5 M, leading to premature wear or even tire failure.
Most forums and owner feedback suggest sticking with the stock size unless you have a specific reason to change. If you still want to explore smaller options, consult with a tire professional to ensure compatibility with your vehicle.
Largest Tire Size
On the rear, the stock tire size is 315/35R20, which is already quite large. Some enthusiasts have considered going larger, such as 325/30R20, but this can lead to complications.
- Clearance Issues: Larger tires can rub against the wheel wells, especially when turning or going over bumps.
- Handling Dynamics: Increasing the size can alter the vehicle’s handling characteristics, making it less predictable.
- Cost: Larger tires tend to be more expensive, both in terms of initial purchase and ongoing maintenance.
If you do opt for larger tires, ensure you have the right suspension setup to accommodate the change.
