Considerations for Tire Replacement
When replacing tires, it’s essential to stick to the recommended size unless you have a specific reason to change it. Here are some considerations:
- Performance: The stock tire size is engineered for performance. Deviating from this can impact handling and acceleration.
- Safety: Using the correct tire size is crucial for maintaining traction and stability, especially in adverse weather conditions.

Aftermarket Options
