Understanding Tire Size

- R – This indicates that the tire is of radial construction, which is the standard for modern tires.
- 18 – This is the diameter of the wheel in inches that the tire is designed to fit.
Tire Performance and Handling
The stock tire size of the 2020 Subaru WRX STI is designed for optimal performance. Here are some points to consider regarding tire performance:
- Grip: Wider tires like the 245mm width provide increased surface area for better traction, especially in corners.
- Stability: The low profile of the 40 aspect ratio enhances stability during high-speed maneuvers.
- Response: The combination of width and aspect ratio allows for quicker steering response, which is essential for a performance car.
Aftermarket Tire Options
If you’re considering upgrading or changing your tires, it’s essential to stick close to the stock size for optimal performance. However, you might want to explore different tire brands or types, such as:
- Performance tires for enhanced grip on dry roads.
- All-season tires if you live in an area with varying weather conditions.
- Winter tires for improved traction in snow and ice.
In summary, understanding the tire size of your 2020 Subaru WRX STI is crucial for maintaining its performance and handling. Whether you’re sticking with stock options or looking into aftermarket alternatives, make sure to keep the specifications in mind to get the most out of your driving experience.
