2015 Ford Focus ST Tire Size: Stock Options

2015 Ford Focus ST Tire Size

When it comes to the 2015 Ford Focus ST, one of the most crucial aspects that can affect your driving experience is the tire size. As an auto owner, understanding the stock tire size not only helps with performance but also ensures safety and handling. Here’s what you need to know.

Stock Tire Size

The stock tire size for the 2015 Ford Focus ST is 235/40R18. This size is designed to provide a balance between performance and comfort, making it ideal for both daily driving and spirited runs.

Understanding Tire Size Breakdown

To make sense of the tire size, let’s break it down:

• 235: This is the width of the tire in millimeters. A wider tire can provide better grip, especially during cornering.
• 40: This number represents the aspect ratio, which is the height of the tire’s sidewall as a percentage of its width. A lower ratio means a shorter sidewall, which generally enhances handling but can result in a stiffer ride.
• R: This indicates that the tire is of radial construction, which is standard for most modern vehicles.
• 18: This is the diameter of the wheel in inches that the tire is designed to fit.

Performance and Handling

Using the correct tire size is not just about fitting them onto your wheels. The 235/40R18 size is specifically chosen for the Focus ST to enhance performance characteristics. Here’s what you should keep in mind:

• Wider tires provide better traction, especially in wet conditions.
• The lower profile helps maintain stability during high-speed maneuvers.
• Proper tire pressure is essential for optimal performance. For the Focus ST, a recommended pressure of 32 psi is standard.

Aftermarket Options

If you’re considering going for aftermarket tires, it’s important to stick close to the stock size or consult a professional. Deviating too much from the 235/40R18 size can lead to issues such as poor handling, increased tire wear, and even safety hazards. Always check with a trusted mechanic or tire specialist before making changes.

Final Thoughts on Tire Maintenance

Regular tire maintenance is crucial. Ensure you check your tire pressure frequently, inspect for uneven wear, and rotate your tires as recommended. Keeping your tires in good shape not only enhances performance but also extends their lifespan.

For more detailed specifications and recommendations, you can refer to the official Ford owner’s manual or consult with a reputable tire dealer. Remember, the right tire can make all the difference in how your Focus ST performs on the road.
