2017 Ford Fusion Bolt Pattern – The Complete Guide To Proper Wheel
The 2017 Ford Fusion utilizes a 5x108mm bolt pattern, a specification it shares with several other Ford and Volvo platforms. Knowing this measurement, along with the 63.4mm center bore, ensures that any aftermarket wheels you purchase will seat securely and safely on your hubs.
Selecting the perfect set of wheels for your sedan is one of the most rewarding upgrades you can make. However, looking at a wall of rims can be overwhelming if you aren’t sure which numbers actually matter for your car. If you get the fitment wrong, you risk vibrations, suspension damage, or even a wheel coming loose while driving.
In this guide, I will break down everything you need to know about the 2017 ford fusion bolt pattern and related wheel specs. We will look at lug nut torque, offset considerations, and how to avoid the common mistakes that catch many DIY mechanics off guard. By the end of this article, you will have the confidence to choose and install wheels like a seasoned technician.
Whether you are looking to improve your Fusion’s stance or simply need a second set of rims for winter tires, getting the fundamentals right is the first step. Let’s dive into the technical details and clear up the confusion surrounding wheel compatibility.
Understanding the 2017 ford fusion bolt pattern
The 2017 ford fusion bolt pattern is officially classified as 5x108mm. In the world of automotive measurements, this means the wheel uses five lug holes arranged in a circle with a diameter of 108 millimeters. If you are more familiar with imperial units, this is roughly equivalent to 5×4.25 inches, though most modern shops use the metric designation.
This specific pattern is quite common across the Ford lineup from this era, appearing on the Focus and the Escape as well. However, just because the holes line up doesn’t mean every 5×108 wheel is a perfect match. You must also consider the physical dimensions of the wheel studs and the space available inside the wheel well.
When shopping for wheels, you might see “5×108” listed for many European cars like Jaguars or older Ferraris. While the pattern matches, the load ratings and offset requirements for a mid-sized sedan like the Fusion are unique. Always verify that the wheel is rated for the weight of your specific trim, especially if you drive the heavier Hybrid or Energi models.
Metric vs. Imperial Measurements
While some older charts might list the 2017 ford fusion bolt pattern in inches, I strongly recommend sticking to metric. Modern manufacturing tolerances are very tight, and a “close enough” conversion can lead to buying wheels that don’t quite slide over the studs. Precision is your best friend when it comes to rotational components.
If you are measuring your existing wheels at home, remember that on a 5-lug system, you measure from the back of one hole to the center of the second hole across from it. This can be tricky to get right with a standard tape measure. Using a dedicated bolt pattern gauge is a much more reliable method for DIYers.
The Importance of the Center Bore and Hub-Centric Design
The bolt pattern is only half of the equation when it comes to a safe fit. The 2017 Ford Fusion uses a 63.4mm center bore. This is the diameter of the hole in the center of the wheel that fits over the hub of the car. Ford designs these vehicles to be hub-centric, meaning the hub carries the weight of the car, not the lug studs.
If you buy aftermarket wheels with a larger center bore (like 73.1mm), the wheel will technically “fit” the 2017 ford fusion bolt pattern, but it won’t be centered perfectly. This creates a gap between the hub and the wheel. Without a snug fit, you will likely experience a persistent steering wheel shake that no amount of balancing can fix.
To solve this, you must use hub-centric rings. These are small plastic or metal spacers that bridge the gap between the car’s 63.4mm hub and the wheel’s larger opening. I always tell my fellow enthusiasts: never skip the rings. They are inexpensive insurance against vibration and stud failure.
Why Lug-Centric is a Risk
Some cheap wheels are designed to be “lug-centric,” meaning they rely on the tapered lug nuts to center the wheel. While this works for some heavy-duty trucks, it is not ideal for the Fusion. Relying solely on the studs to center the wheel puts shear stress on the bolts, which can lead to them snapping under heavy braking or cornering.
Wheel Offset and Backspacing for the Fusion
Once you have confirmed the 2017 ford fusion bolt pattern, you need to look at the offset. Offset (measured in millimeters and marked as “ET”) determines how far the wheel sits in or out of the wheel well. For the 2017 Fusion, the factory offset typically ranges from +45mm to +55mm depending on the trim level and wheel width.
A higher positive offset pushes the wheel further into the fender, while a lower offset pushes it out toward the edge of the car. If you go too low (for example, +30mm), your tires might rub against the fender liner when you hit a bump or turn the wheel sharply. This is a common issue for those trying to achieve a “flush” look.
Conversely, if the offset is too high, the inside of the wheel or tire might contact the strut assembly or brake components. This is especially critical on the Fusion Sport trim, which features larger brake calipers that require specific spoke clearance. Always do a “test fit” on the front hub before mounting tires to your new rims.
Backspacing vs. Offset
While offset is measured from the center of the wheel, backspacing is measured from the mounting surface to the back edge of the rim. For the Fusion, most 8-inch wide wheels will have a backspacing around 6 inches. If you are looking at custom off-road or deep-dish styles, keep these measurements in mind to avoid hitting your suspension links.
Essential Lug Nut Specs and Torque Settings
The 2017 Ford Fusion uses M12 x 1.5 lug nuts. This means the studs are 12mm in diameter with a 1.5mm thread pitch. Using the wrong thread pitch will ruin your studs instantly, requiring an expensive trip to the shop to have them pressed out and replaced. Always hand-start your lug nuts to ensure they aren’t cross-threading.
The proper torque specification for these lug nuts is 100 lb-ft (135 Nm). Over-tightening can stretch the studs or warp your brake rotors, leading to a “pulsing” feeling when you step on the brakes. Under-tightening is obviously dangerous, as the wheel could vibrate loose over time.
When you install your wheels onto the 2017 ford fusion bolt pattern, always use a calibrated torque wrench. Avoid using an impact wrench for the final tightening. Tighten the nuts in a “star pattern” (skipping every other nut) to ensure the wheel seats evenly against the hub surface.
A Note on Ford’s “Swollen” Lug Nuts
If you are still using the factory lug nuts, you might notice they become difficult to fit into a 19mm socket. Ford used a two-piece design with a chrome cap that often traps moisture and swells. I highly recommend replacing these with one-piece solid steel lug nuts. It’s a small upgrade that prevents a massive headache if you ever get a flat tire on the side of the road.
Step-by-Step Guide to Changing Your Wheels
- Safety First: Park on a level surface, engage the parking brake, and chock the wheels that will remain on the ground.
- Loosen the Nuts: While the car is still on the ground, use a 19mm socket and a breaker bar to loosen the lug nuts about half a turn.
- Lift the Vehicle: Use a floor jack on the designated pinch weld jacking points. Once lifted, always secure the car with a jack stand.
- Remove the Wheel: Take the lug nuts off the rest of the way and pull the wheel straight off the studs.
- Clean the Hub: Use a wire brush to remove any rust or debris from the hub face. A clean surface ensures the new wheel seats perfectly on the 2017 ford fusion bolt pattern.
- Install the New Wheel: Slide the new wheel onto the studs. If using hub-centric rings, ensure they are seated in the wheel or on the hub first.
- Tighten by Hand: Spin the lug nuts on by hand until they are snug. This prevents cross-threading.
- Lower and Torque: Lower the car until the tire just touches the ground. Use your torque wrench to tighten to 100 lb-ft in a star pattern.
After driving about 50 to 100 miles on new wheels, it is a “pro” move to re-check the torque. Aluminum wheels can sometimes compress slightly after the initial heat cycle, and a quick click of the torque wrench provides peace of mind.
Frequently Asked Questions About 2017 ford fusion bolt pattern
Can I use wheels from a Ford Mustang on my Fusion?
Generally, no. Most modern Mustangs use a 5×114.3mm bolt pattern, which is larger than the 2017 ford fusion bolt pattern of 5x108mm. Even if you used adapters, the offset on Mustang wheels is usually too aggressive for a Fusion’s fenders.
What is the largest wheel size that fits the 2017 Fusion?
The Fusion can comfortably fit up to 20-inch wheels if the tire profile is adjusted accordingly. Factory options went up to 19 inches on the Titanium and Sport trims. If you go larger than 20 inches, you will likely suffer a very harsh ride and risk bending rims on potholes.
Do I need different lug nuts for aftermarket wheels?
Most likely, yes. Factory Ford wheels use a “large acorn” seat, while many aftermarket wheels require a “tapered” or “conical” seat with a smaller diameter (often called “tuner lugs”). Using the wrong seat type will prevent the wheel from securing properly to the 2017 ford fusion bolt pattern.
Will 5×110 wheels fit my 2017 Ford Fusion?
No. While 2mm sounds like a tiny difference, a 5×110 wheel will not slide over the studs of a 5×108 hub. Never attempt to “force” a wheel on or use “wobble bolts” to bridge the gap, as this is a major safety hazard.
Final Thoughts on Choosing Your Wheels
Upgrading your wheels is one of the best ways to personalize your ride, but safety should always be your North Star. By sticking to the 2017 ford fusion bolt pattern of 5x108mm and ensuring you have the correct 63.4mm center bore, you are already ahead of the curve. Don’t forget to account for the offset to keep your tires from rubbing and use a torque wrench for every installation.
If you ever feel unsure about a specific wheel’s fitment, don’t hesitate to reach out to a professional tire shop. They can verify load ratings and clearance for your specific brakes. Taking the extra time to measure twice will save you time, money, and frustration in the long run.
Now that you have the technical specs in hand, it’s time to find that perfect set of rims. Stay safe, double-check your torque, and enjoy the new look of your Ford Fusion!
