Understanding Tire Size Notation
Before diving into the specifics, it’s important to understand how tire sizes are denoted. A typical tire size is represented as follows:

Tire Sizes by Trim Level
The 2017 BMW 320i comes in several trims, each with its own set of tire specifications. Below is a breakdown of the tire sizes for each trim.
| Trim Level | Front Tire Size | Rear Tire Size | Wheel Diameter |
|---|---|---|---|
| 320i Base | 225/50R17 | 225/50R17 | 17 inches |
| 320i xDrive | 225/45R18 | 225/45R18 | 18 inches |
| 320i Sport Line | 225/40R19 | 255/35R19 | 19 inches |
Base Model: 320i
The standard 320i comes equipped with 225/50R17 tires on both the front and rear. This size provides a decent balance of comfort and handling, making it a solid choice for daily driving.
xDrive Model
For those opting for the xDrive model, the tire size changes to 225/45R18. This slight increase in size improves grip and handling, especially in wet conditions, making it a better option for those who face inclement weather.
Sport Line Model
The Sport Line trim takes performance up a notch with a staggered tire setup. The front tires are 225/40R19, while the rear tires are wider at 255/35R19. This configuration enhances cornering stability and overall performance, but be prepared for a rougher ride due to the lower profile tires.
Choosing the Right Tires
When it comes to replacing tires on your 2017 BMW 320i, consider the following:
- Always match the size specified for your trim level.
- Consider the type of driving you do. Performance tires may be great for spirited driving, but all-season tires provide better versatility.
- Check the tread wear regularly. Worn tires can compromise safety and handling.
- Don’t ignore the age of your tires. Even if they have tread left, tires older than six years should be replaced.
In summary, knowing your 2017 BMW 320i tire size is essential for maintaining your vehicle’s performance and safety. Each trim level offers different tire specifications, so make sure to refer to this guide when it’s time for replacements or upgrades.
Exploring the Smallest and Biggest Tire Sizes for the 2017 BMW 320i
When it comes to the 2017 BMW 320i, tire size isn’t just a number—it’s a critical factor that affects performance, handling, and ride quality. Whether you’re looking to squeeze out every bit of performance or just want a comfortable ride, knowing the smallest and biggest tire sizes available for your vehicle is essential.

Smallest Tire Size for the 2017 BMW 320i
The smallest tire size you will typically find on the 2017 BMW 320i is 225/50R17. This size is standard for the base model and provides a good balance of comfort and handling.
Why Choose the Smallest Size?
Opting for the smallest tire size has its advantages:
- Better ride comfort: The taller sidewall absorbs more road imperfections.
- Cost-effective: Smaller tires are generally less expensive to replace.
- Improved fuel efficiency: Less rolling resistance can lead to better gas mileage.
However, there are trade-offs. While the ride may be more comfortable, you might sacrifice some cornering stability and responsiveness compared to lower-profile tires.

Benefits of Going Bigger
Choosing the biggest tire size offers several benefits:
- Enhanced grip: Wider tires provide more contact with the road, improving traction.
