Exploring Tire Size Options for the 2013 Subaru STI
When it comes to the 2013 Subaru STI, tire size isn’t just a number; it’s a key component that affects performance, handling, and safety. While the stock size is 245/40R18, many owners often explore both smaller and larger tire options to enhance their driving experience. Let’s dive into what the smallest and biggest tire sizes could be, along with recommendations based on owner feedback and forum discussions.
Smallest Tire Size Options
Going smaller than the stock size can be tempting for those looking to improve acceleration and reduce weight. However, it’s crucial to understand the trade-offs.
Recommended Smaller Sizes
- 235/40R18: This size can offer slightly better acceleration and a lighter feel. Owners report a more responsive steering experience, but be cautious as it may compromise grip during aggressive cornering.
- 225/40R18: This is a more extreme option. While it can enhance performance in certain conditions, it significantly reduces contact patch and grip. Most owners advise against this size for daily driving.
Considerations for Smaller Tires
- Reduced grip can lead to instability, especially in wet conditions.
- Speedometer calibration may be affected, leading to inaccurate readings.
- Smaller tires can result in a harsher ride due to less sidewall cushioning.
Biggest Tire Size Options
On the flip side, some owners opt for larger tire sizes to enhance grip and stability. However, going too big can lead to rubbing issues and affect handling.
Recommended Larger Sizes
- 255/35R18: This size is popular among enthusiasts. Many report improved grip and cornering performance. However, you might need to roll the fenders to avoid rubbing.
- 265/35R18: This is pushing the limits. While it offers incredible grip, it can also lead to significant handling changes and may require modifications to the suspension or fender work.
Considerations for Larger Tires
- Increased grip can lead to better cornering but may also affect ride comfort.
- Fuel efficiency can be negatively impacted due to added rolling resistance.
- Potential for rubbing against the fender wells, especially during turns or over bumps.

Performance Tires
- Michelin Pilot Sport PS2: Highly regarded for their grip and responsiveness. Owners love the balance they provide between daily driving and track performance.
