Understanding the 2018 F150 wheel bolt pattern is essential for any owner looking to upgrade wheels or perform maintenance. This specific specification dictates the number of lugs and the diameter of the imaginary circle they form, ensuring a proper fit between the wheel and the truck. Getting this wrong can lead to improper installation, safety hazards, and damage to the vehicle's hubs.
2018 Ford F-150 Bolt Pattern Specifications
The bolt pattern for the 2018 Ford F-150 is 6x135mm, which is represented numerically as 6-135. This configuration features six lug bolts positioned on a circle with a diameter of 135 millimeters. This standard pattern is common across many trucks and SUVs, making it easier to find aftermarket wheels, although verifying the specific fitment for your particular trim and year is always necessary before purchasing new wheels.
Decoding the 6-135 Marking
The marking 6-135 breaks down into two critical measurements for wheel fitment. The number "6" indicates the total count of lug nuts or bolts on the wheel hub. The number "135" refers to the pitch circle diameter (PCD), which is the diameter of an imaginary circle drawn through the center of each lug hole. This measurement is crucial because it determines the wheel's center bore and how it aligns with the truck's hub.
Why Correct Bolt Pattern Matters for Your F150
Ensuring the 2018 F150 wheel bolt pattern matches your vehicle is about more than just aesthetics; it's a fundamental safety requirement. A wheel with an incorrect pattern might physically mount onto the hub but will not be properly secured by the lug nuts. This misalignment can cause the wheel to vibrate excessively, loosen over time, or even fail while driving, leading to a serious accident.
Compatibility with Aftermarket Wheels
One of the primary reasons owners research the 6-135 pattern is for aftermarket wheel upgrades. The good news is that this is a widespread specification, offering a vast selection of rims in various sizes, finishes, and designs. When shopping, you can confidently filter for 6-135 wheels, but you must also check other specifications like offset, backspacing, and center bore to guarantee a perfect and safe fit.
Measuring Your Wheel Pattern Accurately If you are unsure of your wheel pattern, measuring it is a straightforward process. For a 6-lug pattern like the 2018 F150, you can measure the distance between the center of one lug hole to the center of the hole directly opposite it. This measurement should be approximately 135mm. Alternatively, you can count the lugs on the hub; if there are six, and the truck is a 2018 model, the pattern is almost certainly 6-135. Additional Considerations for F150 Wheel Fitment
If you are unsure of your wheel pattern, measuring it is a straightforward process. For a 6-lug pattern like the 2018 F150, you can measure the distance between the center of one lug hole to the center of the hole directly opposite it. This measurement should be approximately 135mm. Alternatively, you can count the lugs on the hub; if there are six, and the truck is a 2018 model, the pattern is almost certainly 6-135.
While the bolt pattern is the primary concern, other factors play a significant role in the overall fitment of wheels on your 2018 F150. The offset determines how the wheel sits relative to the fender, and the backspacing measures the distance from the mounting surface to the back edge of the wheel. Ensuring these measurements align with the vehicle's specifications is vital to prevent rubbing against the suspension or brakes.
Summary of Key Specifications
For quick reference, the 2018 Ford F-150 utilizes a 6-lug, 135mm bolt pattern. This standard allows for compatibility with a wide range of aftermarket wheels designed for full-size trucks. Always double-check this specification, along with offset and center bore, before finalizing any wheel purchase to ensure optimal performance and safety.
