So, you’re staring at a set of wheels, or maybe just thinking about grabbing some aftermarket bits for your 2018 F-150. And the first thing that pops into your head, or maybe the hundredth, is: what the heck is the are 2018 f 150 bolt pattern? It sounds simple, right? Like it should be printed on a sticker somewhere obvious.
For me, it took digging. I remember trying to swap out some stock wheels for a set I scored cheap online. I thought, ‘Easy peasy.’ Turns out, ‘easy peasy’ involves knowing your bolt pattern. I ended up with a very expensive, very useless set of rims sitting in my garage for weeks. Don’t be me.
This isn’t some deep, dark secret. But getting it wrong costs time and money. Let’s cut through the noise and get you the straight dope.
What the Heck Is a Bolt Pattern Anyway?
Look, before we even get into the specifics of your 2018 F-150, you gotta understand what this ‘bolt pattern’ thing is all about. It’s not rocket science, but it is the fundamental handshake between your wheel hub and the wheels you want to slap on. Basically, it’s the diameter of a circle connecting the centers of your lug holes, measured in millimeters (mm), and the number of those holes. For your truck, it’s usually expressed as ‘5x135mm’ or ‘6×139.7mm’, or whatever the specific pattern is. The first number is how many studs (or lug nuts) your hub has, and the second is the diameter of the bolt circle they sit on.
Why does this matter? Simple: if the pattern doesn’t match, the wheel won’t bolt up. Period. You can’t just force it. Trying to force it leads to stripped studs, cracked wheels, and potentially, a wheel coming off your truck. And trust me, nobody wants that kind of excitement. It’s like trying to put a square peg in a round hole, but with way more dangerous consequences if you just keep hammering.
I learned this the hard way trying to put some sweet-looking aftermarket wheels on my old Ranger. They looked identical to the stock ones in pictures. Got ’em delivered, got all excited, jacked up the truck, and… nope. The bolt pattern was just slightly off. Not enough to be obvious from 20 feet away, but definitely enough to make them sit there mocking me. Had to eat the return shipping cost and wait another week for the right set. Lesson learned: measure twice, order once, and always confirm the damn bolt pattern.
Your 2018 F-150: The Specifics You Need
Alright, let’s get down to brass tacks. For the 2018 Ford F-150, the standard bolt pattern you’re going to see, across pretty much all trims and configurations (unless you’ve got some seriously obscure factory option or aftermarket conversion), is 6x135mm. Yeah, six lugs, and the circle they form is 135 millimeters in diameter. This is good news, mostly, because it means there’s a decent selection of wheels out there that will fit without needing adapters or spacers, which can sometimes cause their own set of headaches down the line.
Now, you might be wondering, ‘What about different F-150 models? Does the Raptor have a different one? Or the XL?’ For the 2018 model year, Ford kept it consistent across the board for the F-150 lineup. So whether you’re rocking an entry-level XL, a plush King Ranch, or a beastly Raptor, the 6x135mm pattern is your baseline. This consistency is a big win for anyone looking to swap wheels, buy spares, or just understand what’s compatible.
However, and this is where you gotta pay attention, there are some aftermarket wheels designed with multi-lug patterns. You might see a wheel advertised as ‘6/135, 6/139.7’ or something similar. This means it has two sets of bolt holes drilled into it, allowing it to fit multiple bolt patterns. While this sounds convenient, and sometimes it is, it’s important to make sure the wheel is actually designed for your specific hub bore as well. More on that later. For now, just know that 6x135mm is your target for a direct fit on a stock 2018 F-150. Don’t let anyone tell you different unless you’re talking about a heavily modified vehicle.
| Vehicle | Bolt Pattern | Verdict |
|---|---|---|
| 2018 Ford F-150 (All Trims) | 6x135mm | Direct Fit – Most Common & Recommended |
| Aftermarket Wheels (Multi-Pattern) | Varies (e.g., 6/135, 6/139.7) | Use with Caution – Double-check Hub Bore & Fitment |
| Older F-150s (Pre-2015) | Often 6x135mm or 6×139.7mm | NOT Compatible with 2018 F-150 Without Adapters |
Beyond the Pattern: Offset, Backspacing, and Hub Bore
So you’ve confirmed your 2018 F-150 is a 6x135mm. Great! But that’s only half the battle. If you’ve ever seen wheels that stick out way too far, or tuck in so much you wonder if they’re going to rub the suspension, that’s down to two other key specs: offset and backspacing. These dictate how the wheel sits in relation to the fender and the suspension components.
Offset is the distance from the mounting surface of the wheel (where it bolts to the hub) to the centerline of the wheel. A positive offset means the mounting surface is outboard of the wheel’s centerline, pushing the wheel inward. A negative offset means the mounting surface is inboard of the centerline, pushing the wheel outward. For most stock F-150s with the 6x135mm pattern, you’re generally looking for a low positive offset or a slight negative offset. This can vary slightly depending on the wheel width you choose, but think in the range of +10mm to -20mm for common aftermarket setups that aim for a flush or slightly aggressive stance without major modifications.
Backspacing is the distance from the back of the wheel mounting surface to the back lip of the wheel. It’s measured in inches. Higher backspacing means the wheel sits further inward, closer to the suspension. Lower backspacing pushes it outward. It’s closely related to offset, and if you know one, you can often calculate the other. A typical stock 2018 F-150 wheel might have around 5.5 to 6.0 inches of backspacing. If you go too low, you’ll rub on your fenders. If you go too high, you’ll rub on your control arms or brake calipers. (See Also: Are All Honda Atv Bolt Patterns The Same )
And then there’s the hub bore. This is the raised lip on your truck’s hub assembly that the center hole of the wheel seats onto. It’s designed to center the wheel precisely.
Most aftermarket wheels that are designed for your 6x135mm F-150 will have a hub bore that matches Ford’s specification, or they’ll be designed with a larger bore and come with ‘hub-centric rings’ to adapt them to your truck’s specific hub size. Ford’s hub bore for the 2018 F-150 is 87.1mm.
If a wheel has a larger bore (common on many universal or multi-lug wheels) and doesn’t come with rings, or the rings aren’t the right size, you’re asking for trouble. Wheels that aren’t hub-centric can vibrate at speed, put uneven stress on your studs, and eventually lead to problems.
The Hub Bore Difference: A Personal Tale
I once bought a set of wheels that were advertised as ‘6x135mm compatible.’ They looked great, the price was right, and the seller swore they’d fit my F-150.
Turns out, they had a massive universal hub bore. They included some plastic rings, but they felt flimsy. I installed them, and from the moment I hit 40 mph, the truck vibrated like it was having a seizure.
I thought it was the tires. Balanced them. Same thing.
Took it to a shop, and the mechanic pointed out how the wheel wasn’t perfectly centered on the hub. He said those plastic rings were basically useless for anything beyond parking lot speeds. I ended up selling those wheels at a loss and buying a set that was specifically designed for the F-150 with the correct 87.1mm hub bore.
The difference in ride quality was night and day. No more vibrations, just smooth cruising. Don’t skimp on the hub-centric rings, or better yet, get wheels with the right hub bore from the start.
Common Mistakes and How to Avoid Them
You’d think with something as seemingly straightforward as a bolt pattern, people wouldn’t screw it up. But oh, they do. And it’s usually the same few dumb mistakes that cost people time, money, and sometimes a lot of frustration. The biggest one, obviously, is just not knowing the correct 2018 F-150 bolt pattern (which is 6x135mm, remember?). People see a cool wheel on another truck and assume it’ll fit theirs. Bad assumption.
Another big one is confusing bolt patterns with other Ford trucks or even other brands. Ford has used 5×139.7mm (often called 5×5.5) on older F-150s and some other models. Chevrolet and GMC trucks often use 6×139.7mm (6×5.5). They look similar, especially if you’re only looking at the number of lugs, but they absolutely will not interchange. You need the specific 6x135mm for your 2018 F-150.
Then there’s the whole adapter and spacer thing. Some folks will buy wheels with a completely different bolt pattern and then slap on a set of adapters to make them fit. While this can work, it adds complexity and potential failure points. Adapters increase your unsprung weight, can mess with your steering feel, and if they’re not installed perfectly, can lead to serious safety issues. I’m not saying never use them, but if you can find wheels with the correct 6x135mm bolt pattern and appropriate offset/backspacing, that’s almost always the better, simpler, and safer route. I’ve seen too many people have issues with adapters loosening or causing weird vibrations down the road. (See Also: Are Ak Bolts Interchangeable )
Finally, don’t just trust the online fitment guides blindly. Yes, they’re usually helpful, but they can have errors. Always double-check the manufacturer’s specs for the wheel you’re interested in and compare it against your truck’s known specs. If there’s any doubt, pick up the phone and call the wheel manufacturer or a reputable tire shop. Better safe than sorry.
When Adapters Might Be Necessary (but Still Risky)
There are situations where you might really want a wheel that doesn’t have the 6x135mm bolt pattern. Maybe it’s a vintage wheel you love, or a specific off-road wheel that only comes in a common 8-lug pattern or a 6×139.7mm. In these rare cases, wheel adapters can be used.
These are basically thick plates that bolt to your truck’s hub and then provide a new set of studs for the desired bolt pattern. However, they add width to your stance, can increase stress on your wheel bearings, and require meticulous installation.
If you go this route, make sure you’re buying high-quality, reputable adapters, torque them to spec, and re-check them frequently. I’ve seen them cause significant problems when they’re cheap or installed incorrectly.
Real-World Implications: What Happens When It’s Wrong
Let’s be blunt: getting the wrong bolt pattern for your 2018 F-150 isn’t just an inconvenience; it can be downright dangerous. I’ve already touched on vibrations, but it goes deeper.
First, there’s the immediate problem of the wheel not fitting. You can’t bolt it on. If you try to force it, you risk damaging the studs on your truck, which are pretty beefy but not invincible. Stripped studs are a pain in the backside to replace, often requiring you to remove the hub assembly. If you manage to get it on, but it’s not seated correctly because the pattern is slightly off, you’re asking for trouble.
This is where the real danger lies. A wheel that isn’t seated perfectly flush against the hub assembly is under immense stress. The lugs are trying to hold it in place, but they aren’t aligned correctly with the studs.
Over time, this can lead to the wheel wobbling, the studs elongating or breaking, and in the worst-case scenario, the wheel coming off the vehicle while you’re driving. I had a buddy whose aftermarket wheel cracked right at the lug holes after he’d been running them for a few months with a slightly questionable fit.
He was lucky it happened at a low speed in a parking lot. The sheer forces involved in driving, braking, and turning put incredible strain on that connection.
Beyond the safety aspect, there’s the financial hit. You might have to pay restocking fees and return shipping for incorrect wheels. If you damage your studs or your hub, that’s an immediate repair bill. And if you’ve already had tires mounted on the wrong wheels, that’s another expense to consider. It’s way cheaper and less stressful to get it right the first time by understanding the are 2018 f 150 bolt pattern and its associated specs.
Common Lsi Keyword Integration Example: Wheel Fitment Guide
When you’re looking for new wheels, you’ll often come across a ‘wheel fitment guide.’ These are usually online tools provided by tire and wheel retailers. They ask for your vehicle’s make, model, and year, and then they present you with wheels that are supposed to fit. While these guides are incredibly helpful for giving you a starting point and can quickly narrow down your options based on the 6x135mm bolt pattern, it’s still your responsibility to do a final check. (See Also: Are All Bolt Patterns The Same )
Sometimes, they might not account for specific suspension modifications you might have, or they could have a slight database error. Always cross-reference the recommended wheel specs (bolt pattern, offset, backspacing, hub bore) with what you know about your truck. It’s an extra step that can save you a world of hurt.
Where to Find Reliable Information and Wheels
Okay, so you know the 2018 F-150 uses a 6x135mm bolt pattern, you understand offset and backspacing, and you’ve learned about the hub bore. Where do you go from here to actually get wheels that fit and look good?
First off, your truck’s owner’s manual is your friend. While it might not scream the bolt pattern in large, bold letters on the first page, it’s usually buried somewhere in the specifications section. It’s the most official source for your vehicle’s stock specs. If you can’t find it or it’s not clear, the next best thing is to check the manufacturer’s website. Ford’s official site often has detailed specs for their vehicles, or at least links to resources that do. I’ve found that sometimes searching for ‘Ford F-150 2018 specifications bolt pattern’ on Google will lead you directly to an official Ford document or a reputable automotive site quoting the official specs.
When you’re looking at purchasing wheels, reputable online retailers are a great resource. Sites like Tire Rack, Discount Tire, AmericanTrucks, and others have extensive databases. They’ll typically have a vehicle selector that will filter wheels by the correct bolt pattern, offset, and other fitment criteria. Always look for a ‘fitment guarantee’ or a note that says the wheels are guaranteed to fit your specific vehicle. These companies usually have a vested interest in getting it right, and if they say a wheel fits, it generally does.
Don’t be afraid to call them. Seriously. The sales reps at these places deal with this stuff all day. Tell them what year and model F-150 you have, and ask them to confirm the bolt pattern, the ideal offset range for a flush look, and the hub bore. They can also advise on tire sizes that will complement the new wheels and your truck’s suspension.
Lastly, truck forums and communities are goldmines of real-world experience. Guys and gals who have already put aftermarket wheels on their 2018 F-150s are often happy to share what worked, what didn’t, and what brands they recommend. Just be sure to filter the information; not everyone’s setup is stock, and some people have done significant modifications that might not apply to you. But for general fitment and honest opinions on how wheels look and perform, these forums are invaluable.

People Also Ask (faq)
Will Wheels From a 2017 F-150 Fit a 2018 F-150?
Yes, in most cases, wheels from a 2017 F-150 will fit a 2018 F-150. Ford maintained the same 6x135mm bolt pattern and similar hub bore specifications for these model years. However, it’s always wise to double-check the offset and backspacing to make sure a perfect fit without rubbing, especially if the 2017 truck had a different trim level or factory wheel option.
Can I Use Wheels with a 6×139.7mm Bolt Pattern on My 2018 F-150?
No, you cannot directly use wheels with a 6×139.7mm bolt pattern on your 2018 F-150. The 2018 F-150 requires a 6x135mm bolt pattern. While adapters exist to convert between bolt patterns, they add complexity, potential stress points, and can alter your vehicle’s driving dynamics. It’s generally recommended to find wheels designed for the correct 6x135mm pattern for optimal safety and performance.
What Is the Hub Bore Size for a 2018 F-150?
The hub bore size for a 2018 Ford F-150 is 87.1mm. This measurement refers to the diameter of the raised lip on your truck’s hub that the center hole of the wheel seats onto. Using wheels with the correct hub bore or appropriate hub-centric rings is important for proper wheel centering and to prevent vibrations and uneven stress on your studs.
Do I Need Hub-Centric Rings If My Aftermarket Wheels Have a Larger Bore?
Yes, if your aftermarket wheels have a larger hub bore than your truck’s 87.1mm, you will need hub-centric rings to make sure the wheel is properly centered on the hub. Without them, the wheel will be relying solely on the lug nuts for centering, which can lead to vibrations at speed, uneven tire wear, and potential damage to your wheel studs and bearings. Always use high-quality rings that precisely match the wheel bore and your truck’s hub bore.
Final Thoughts
So there you have it. The 2018 F-150 runs a 6x135mm bolt pattern. It’s not a mystery, but it’s a detail you absolutely cannot afford to ignore. Getting this wrong is a fast track to wasted cash and potential headaches, at best, or serious safety issues, at worst.
Before you click ‘buy’ on those shiny new wheels or that interesting Craigslist find, take a moment. Verify the bolt pattern. Check the offset and backspacing. Make sure the hub bore situation is sorted. Your truck will thank you, your wallet will thank you, and your commute will be a lot smoother.
Don’t just assume. Do your homework. It’s the only way to make sure your truck looks good and stays on the road safely.
