Finding the right rim size for your Ford Focus ST is crucial for performance, handling, and overall aesthetics. This guide delves into the intricacies of Ford Focus ST rim sizes, covering factory specifications, aftermarket options, and important considerations for choosing the perfect fit.
Understanding Ford Focus ST Rim Sizes: Factory Specifications
The factory-recommended rim size for the Ford Focus ST varies slightly depending on the model year and trim level. However, common sizes include:
-
18 inches: This is a prevalent size across various Focus ST model years, offering a good balance between performance and ride comfort. You'll often find this size paired with specific tire dimensions for optimal handling.
-
19 inches: Some higher trim levels or specific model years might feature 19-inch rims. These larger rims generally contribute to a sportier look and potentially improved handling at the cost of a slightly harsher ride.
Important Note: Always verify the exact rim size specified on your vehicle's documentation or the sticker located inside the driver's side doorjamb. This information is critical for ensuring compatibility.
Aftermarket Rim Options for Your Ford Focus ST
While sticking to the factory-recommended size is generally advisable, the aftermarket offers a wide selection of rims for the Ford Focus ST. Choosing aftermarket rims allows for customization and personalization, enabling you to achieve your desired aesthetic. However, careful consideration is needed to ensure proper fitment.
Factors to Consider When Choosing Aftermarket Rims:
-
Bolt Pattern: The Ford Focus ST uses a specific bolt pattern (number of lug nuts and their arrangement). Using the incorrect bolt pattern is extremely dangerous and can lead to wheel failure. Always confirm the bolt pattern matches your vehicle's specifications.
-
Wheel Offset: Offset refers to the distance between the wheel's mounting surface and its centerline. Incorrect offset can cause rubbing against the suspension or body, affecting handling and potentially causing damage.
-
Diameter: While you might consider larger or smaller rims than the factory standard, remember that changing the diameter impacts the overall rolling diameter, which can affect your speedometer accuracy and potentially your vehicle's performance characteristics.
-
Width: Rim width impacts tire choice and overall handling. Too wide a rim might cause tire issues, while too narrow a rim may not provide sufficient support.
-
Tire Compatibility: Remember that changing rim size almost always necessitates changing tire size. Ensure the selected tire size is compatible with your new rims and your vehicle's specifications. Consult a tire size calculator to confirm compatibility.
The Importance of Proper Rim Size Selection
Using the correct rim size is paramount for the following reasons:
-
Safety: Incorrectly sized rims can lead to wheel failure, compromising vehicle safety.
-
Handling: The right rim size contributes to optimal handling and performance.
-
Ride Comfort: Certain rim sizes provide a smoother ride than others.
-
Vehicle Longevity: Using the correct rim size helps prevent damage to other components of your vehicle's suspension and braking systems.
-
Appearance: The chosen rim size significantly influences the aesthetic appeal of your vehicle.
