The Ford Focus is one of the most popular compact cars in the world, known for its reliability, fuel efficiency, and sleek design. If you own a Ford Focus or are considering buying one, you might have questions about its bolt pattern. Understanding the Ford Focus bolt pattern is essential when upgrading your wheels, changing rims, or ensuring a proper fit. In this article, we will explore the Ford Focus bolt pattern in detail, covering different model years, variations, and tips for choosing the right wheels.
What Is a Bolt Pattern?
A bolt pattern, also known as a lug pattern or PCD (Pitch Circle Diameter), is the arrangement of lug holes on a wheel. It is typically measured by counting the number of lug holes and measuring the diameter of the circle they form. The Ford Focus bolt pattern determines which aftermarket or replacement wheels will fit correctly on your car.
Ford Focus Bolt Pattern by Model Year
The Ford Focus has been in production since 1998, and its bolt pattern has varied over the years. Here is a breakdown of the Ford Focus bolt pattern by generation:
First Generation (1998-2004)
- Bolt Pattern: 4x108mm
- Lug Nut Size: M12x1.5
- Hub Bore: 63.3mm
- Offset: 35-42mm
Second Generation (2005-2011)
- Bolt Pattern: 4x108mm
- Lug Nut Size: M12x1.5
- Hub Bore: 63.3mm
- Offset: 35-42mm
Third Generation (2012-2018)
- Bolt Pattern: 5x108mm
- Lug Nut Size: M12x1.5
- Hub Bore: 63.3mm
- Offset: 35-50mm
Fourth Generation (2019-Present)
- Bolt Pattern: 5x108mm
- Lug Nut Size: M12x1.5
- Hub Bore: 63.3mm
- Offset: 35-50mm
The transition from a 4-lug to a 5-lug pattern happened in the third generation, making it crucial to check your specific model year before purchasing wheels.
Why Does the Ford Focus Bolt Pattern Matter?
The bolt pattern is important because it determines whether a wheel will fit properly on your Ford Focus. If the bolt pattern does not match, the wheel will not mount securely, which can lead to dangerous driving conditions. Using the wrong bolt pattern can cause vibrations, uneven tire wear, and even damage to the suspension system.
How to Measure the Ford Focus Bolt Pattern
If you want to measure your Ford Focus bolt pattern yourself, follow these steps:
- Count the number of lug holes on your wheel. The Ford Focus has either 4 or 5 lugs depending on the model year.
- Measure the distance between the center of one lug hole and the center of the lug hole directly opposite to it. This gives you the diameter in millimeters.
- Write the measurement in the format “4×108” or “5×108,” where the first number represents the number of lugs and the second number represents the diameter in millimeters.
Common Wheel Sizes for the Ford Focus
When selecting wheels for your Ford Focus, it’s important to consider not only the bolt pattern but also the wheel size. Here are the common wheel sizes for different Ford Focus models:
- 15-inch wheels: Found on base models and earlier generations.
- 16-inch wheels: Common on mid-range trims.
- 17-inch wheels: Often seen on sportier trims like the Focus ST.
- 18-inch wheels: Available on performance models.
- 19-inch wheels: Found on high-performance trims like the Focus RS.
Choosing Aftermarket Wheels for the Ford Focus
If you’re looking to upgrade your Ford Focus wheels, consider the following factors:
- Bolt Pattern: Ensure the wheels match the correct bolt pattern (4×108 or 5×108).
- Offset: The offset affects how the wheel sits in relation to the suspension and fenders.
- Hub Bore Size: The hub bore should match the Focus’s 63.3mm bore to ensure a snug fit.
- Tire Size Compatibility: Check that your new wheels will work with your preferred tire size.
Can You Change the Bolt Pattern of a Ford Focus?
It is possible to change the bolt pattern using wheel adapters. However, this is not always recommended, as it can impact the handling and safety of your vehicle. If you must change the bolt pattern, consult a professional mechanic to ensure proper installation.
Ford Focus ST and RS Bolt Pattern Differences
The Ford Focus ST and RS models come with sportier setups, but they still share the same bolt pattern:
- Focus ST (2013-2018): 5x108mm
- Focus RS (2016-2018): 5x108mm
Because these performance models have different suspension setups, you should also consider wheel offset and width when selecting aftermarket wheels.
Frequently Asked Questions
1. Will 5×114.3 wheels fit a Ford Focus? No, 5×114.3 wheels will not fit a Ford Focus unless you use a bolt pattern adapter, which is not recommended for performance or safety reasons.
2. Can I use wheels from another Ford model on my Focus? Some Ford models share the 5x108mm bolt pattern, such as the Ford Fusion, but always check offset and hub bore size before swapping wheels.
3. What is the torque specification for Ford Focus lug nuts? The standard lug nut torque specification for most Ford Focus models is between 100-110 lb-ft (135-150 Nm). Always confirm in your owner’s manual.
Conclusion
Understanding the Ford Focus bolt pattern is crucial for maintaining and upgrading your vehicle’s wheels. Whether you’re replacing stock wheels, upgrading to aftermarket rims, or ensuring compatibility, knowing your car’s bolt pattern, offset, and hub bore will help you make the right choice. Always double-check measurements and consult experts if needed to keep your Focus performing at its best.
