Choosing the right tire size is essential for maintaining optimal performance and safety. In this section, we’ll break down the stock tire sizes for different trims of the 2011 WRX STI.
Stock Tire Sizes by Trim
The 2011 WRX STI comes in a couple of different trims, and each trim has its own recommended tire size. Here’s a quick look at the stock tire sizes for each trim:

Understanding Tire Size
To decipher the tire size, let’s break down what the numbers mean:
- 245 – This number represents the width of the tire in millimeters. A wider tire often provides better grip.
- 40 – This is the aspect ratio, indicating the height of the sidewall as a percentage of the tire’s width. A lower number means a shorter sidewall, which can improve handling.
- R – This letter signifies that the tire is of radial construction, which is standard for most modern tires.
- 18 – This number indicates the diameter of the wheel in inches that the tire is designed to fit.
Why Tire Size Matters
Choosing the right tire size is crucial for several reasons:
- Handling: The correct size contributes to better grip and handling. A wider tire can provide a larger contact patch with the road.
- Speedometer Accuracy: Changing tire sizes can affect your speedometer reading. Stick to the stock size to keep it accurate.
- Ride Quality: The aspect ratio affects how well your car absorbs bumps. A lower profile tire may provide a harsher ride.
- Safety: Using the recommended tire size ensures that your car performs as intended, which is vital for safety.
In summary, the stock tire size for all trims of the 2011 WRX STI is 245/40R18. This uniformity across trims simplifies things for owners when it comes to replacements or upgrades. Make sure to stick with this size unless you have a specific reason to change, and always consult with a professional if you’re unsure.

When it comes to the 2011 Subaru WRX STI, tire size isn’t just a number; it’s a critical factor that can make or break your driving experience. While the stock tire size is 245/40R18, many owners often wonder about the smallest and largest tire sizes that can fit without causing issues. Let’s dive into the options, along with some recommendations based on owner feedback and forum discussions.
Smallest Tire Size Options
Some enthusiasts look to downsize their tires for various reasons, including cost savings or a desire for a softer ride. Here’s what you need to know about the smallest tire size that can work on the 2011 WRX STI.
- 225/40R18: This size is often mentioned in forums as a viable option. It offers a narrower profile, which can improve fuel efficiency and slightly reduce road noise. However, handling might be compromised, especially in aggressive driving conditions.
- 235/40R18: A popular choice among owners looking for a balance between performance and comfort. This size maintains a good contact patch while offering a bit more sidewall height compared to the stock size.
Considerations for Smaller Tires
While smaller tires might seem appealing, there are key factors to keep in mind:
- Handling: A narrower tire can lead to less grip during cornering, which is crucial for a performance car like the WRX STI.
- Speedometer Accuracy: Changing tire sizes can affect the accuracy of your speedometer and odometer readings.
- Ride Quality: Smaller tires may absorb bumps differently, potentially leading to a harsher ride.
Biggest Tire Size Options
On the flip side, some owners opt for larger tires to enhance grip and aesthetics. Here are some of the biggest tire sizes that can fit the 2011 WRX STI:

Considerations for Larger Tires
Going larger comes with its own set of challenges:
- Clearance: Always check for clearance issues, especially if your vehicle is lowered or has aftermarket suspension components.
- Weight: Larger tires can add weight, which may affect acceleration and fuel efficiency.
