Base Model Tire Size Explained
For the WRX Base, the stock tire size is 225/45R17. This size is designed to provide a balance between comfort and performance. Here’s a breakdown of what those numbers mean:
- 225 – This is the width of the tire in millimeters. A wider tire can provide better grip on the road.
- 45 – This number is the aspect ratio, which is the height of the sidewall as a percentage of the width. A lower number means a shorter sidewall, which can improve handling but may lead to a harsher ride.
- R – This indicates that the tire is of radial construction, which is standard for most modern vehicles.
- 17 – This is the diameter of the wheel in inches. The 17-inch wheels on the WRX Base are a good compromise for performance and ride quality.
Benefits of Stock Tire Size
Sticking with the stock tire size is generally recommended for a few reasons:
- Performance: The tires are specifically chosen to match the vehicle’s suspension and handling characteristics. Deviating from this can affect how the car drives.
- Safety: Using the correct tire size ensures that the speedometer and odometer readings are accurate, which is crucial for monitoring speed and distance.
- Warranty: If your WRX is still under warranty, using non-standard tire sizes could potentially void certain aspects of that warranty.
Considerations for Upgrading Tires
If you’re thinking about upgrading your tires, consider the following:
- What kind of driving do you do? If you mainly drive in wet or snowy conditions, an all-season tire may be better than a summer tire.
- Are you planning to track your WRX? If so, performance tires could enhance your driving experience.
- Check your wheel size. If you decide to upgrade to a larger wheel, you’ll need to ensure that the new tire size is compatible with your vehicle’s specifications.
In summary, understanding the stock tire size for the 2018 WRX Base is essential for maintaining optimal performance and safety. Whether you’re sticking with the factory tires or considering an upgrade, knowledge is key to making the right choice for your driving needs.
