Pros and Cons of Larger and Smaller Tires

Choosing the right tire size for your vehicle can be a daunting task. While the recommended tire size for Subaru Legacy is 225/55R17, you may be wondering if larger or smaller tires can offer better performance.

Larger Tires

A wider tire has a larger contact patch, which provides more traction, especially in wet or slippery conditions. Additionally, a larger tire has a shorter sidewall, which reduces flexing and improves the tire’s cornering ability.

However, smaller tires have a few downsides. They have a smaller contact patch, which can reduce traction and handling, especially in wet or slippery conditions. They also have a taller sidewall, which can lead to more flexing and a less precise steering feel.
