- 235 – This is the tire width in millimeters. A wider tire generally provides better grip and stability.

Why Tire Size Matters
Choosing the right tire size goes beyond just fitting them onto your wheels. It impacts several key areas:
- Handling: The stock size is optimized for the Focus ST’s performance. Deviating from this size can alter handling characteristics.
- Safety: Tires that are too wide or too narrow can affect braking distances and stability, especially in wet conditions.
- Fuel Efficiency: Incorrect tire sizes can lead to increased rolling resistance, which can hurt your fuel economy.
- Wear and Tear: Using non-stock tires can lead to uneven wear, affecting not just the tires but also the suspension and alignment.
Aftermarket Options
If you’re considering upgrading or replacing your tires, here are some common options that fit the stock size:
- Performance Summer Tires: Great for grip in dry conditions.
- All-Season Tires: Versatile but may sacrifice some performance.
- Track Tires: Designed for maximum grip but not suitable for daily driving.
When selecting aftermarket tires, always stick to the stock size unless you know what you’re doing. Going too wide or too narrow can lead to a host of issues.
Remember, keeping your tires in good shape is essential for maintaining the performance and safety of your 2017 Ford Focus ST. Regular checks for tread wear and proper inflation can go a long way in ensuring your ride remains smooth and responsive.
