In this section, we will dive into some popular alternative tire sizes and the best tire models based on owner feedback and forum discussions.

Understanding Alternative Tire Sizes

Before we jump into specific tire models, it’s essential to understand what alternative tire sizes mean for your WRX. Changing tire sizes can affect handling, ride comfort, and even speedometer accuracy. Here are some common alternative sizes that WRX owners often consider:

A common upgrade for WRX owners, this size is often used in the STI models. It gives a sportier feel and improves cornering ability. Many enthusiasts swear by this size for track days and spirited driving.

235/40R17

If you’re looking for maximum grip, this size is often recommended. It provides a larger contact patch, which can enhance traction significantly. However, be mindful that it may affect ride comfort and could lead to rubbing issues if not paired with the right wheel offset.
