The 2014 Ford Trucks F-150 FX4 sits in the modern half-ton pickup era where off-road styling and everyday usability often came together in one package. Buyers looking at this exact FX4 are usually balancing truck capability, appearance, and the realities of how the truck is actually equipped today. Tire fitment centers on two radial sizes, 275/55R20 and 275/65R18, and the right choice depends first on wheel diameter and then on the specific cab configuration. That makes this a fitment-first decision rather than a broad brand search. For an owner replacing worn tires, the key is matching the truck's actual wheel setup before comparing sidewall style, load specification, and tire series.
Which Tire Size Is Right for The 2014 Ford Trucks F-150 FX4
The 2014 Ford Trucks F-150 FX4 uses two primary tire sizes, and they do not share the same rim diameter. One size fits an 18-inch wheel and the other fits a 20-inch wheel, so confirming the truck's actual wheel diameter is the first step before selecting a tire. Sub-model also matters here, since the Reg. Cab and the Super Crew/Super Cab configurations do not all use the same size.
The size 275/55R20 identifies a radial tire that is 275 millimeters wide, uses a 55-series aspect ratio, and mounts on a 20-inch rim. On the 2014 Ford Trucks F-150 FX4, this is one of the primary modern radial fitments and is tied directly to trucks equipped with 20-inch wheels. Its overall proportions differ from the 18-inch fitment, even though both share the same nominal section width. This size should be chosen only after confirming the truck's wheel diameter and exact FX4 configuration, especially on trucks that may have had wheel changes over time.
The size 275/65R18 is a metric radial with a 275-millimeter section width, a 65-series profile, and an 18-inch rim diameter. For the 2014 Ford Trucks F-150 FX4, this size applies to certain Super Crew and Super Cab configurations using 18-inch wheels. Available product choice in this size includes BFGoodrich's All-Terrain T/A KO2 with raised white letter sidewalls, giving it a more aggressive truck presentation. This fitment makes the most sense for an owner who has confirmed an 18-inch wheel package and wants to compare load, rim-width compatibility, and intended road or light off-road use.
Sub-model fitment matters on the 2014 Ford Trucks F-150 FX4 because tire size is not completely uniform across the covered configurations. The first step is identifying whether the truck is a Reg. Cab or a Super Crew/Super Cab, then confirming whether it carries 18-inch or 20-inch wheels.

Tire Size & Fitment
What tire size fits a 2014 Ford Trucks F-150 FX4?
The 2014 Ford Trucks F-150 FX4 uses two primary radial tire sizes: 275/55R20 and 275/65R18. The 275/55R20 size is used on the Reg. Cab, while the Super Crew/Super Cab can use either 275/55R20 or 275/65R18 depending on the truck's wheel setup.
The important next step is checking the actual wheels on the truck rather than assuming every FX4 uses the same size. A 20-inch wheel requires 275/55R20, while an 18-inch wheel requires 275/65R18, so verifying the current wheel diameter avoids an easy fitment mistake.
What size rim does a 2014 Ford Trucks F-150 FX4 use?
A 2014 Ford Trucks F-150 FX4 can use either an 18-inch or a 20-inch rim, depending on the tire size installed. The 275/65R18 tire mounts on an 18-inch rim, and the 275/55R20 tire mounts on a 20-inch rim.
That rim difference is the first thing to confirm before shopping for replacement tires. Looking only at the truck's trim name is not enough, especially on Super Crew or Super Cab trucks, because wheel packages can vary and some trucks may have been changed from their original setup.
Do all 2014 Ford Trucks F-150 FX4 sub-models use the same tire size?
No. The 2014 Ford Trucks F-150 FX4 Reg. Cab uses 275/55R20, while the Super Crew/Super Cab can use 275/55R20 or 275/65R18. That means tire fitment is not uniform across every FX4 body configuration covered here.
Sub-model identification matters because the right tire depends on both body style and wheel diameter. On a truck that has been owned for years, it is smart to confirm the size stamped on the sidewall and compare it to the actual wheel before replacing only one tire or ordering a full set.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Ford Trucks F-150 FX4?
Start with the correct size for the truck's actual setup: 275/55R20 for 20-inch wheels or 275/65R18 for 18-inch wheels. From there, compare radial construction details, the intended use of the truck, sidewall presentation, load specification, and the wheel-width range the tire is built to accommodate.
A truck used mainly on pavement may call for a different overall character than one that sees gravel, trail access, or work duty. The best approach is to match the tire to how the FX4 is driven today while staying within the correct size and wheel requirements.
What sidewall styles are available for 2014 Ford Trucks F-150 FX4 tires?
Among the currently covered options for the 2014 Ford Trucks F-150 FX4, the available 275/65R18 product uses an RWL sidewall. RWL means raised white letter, a traditional truck and SUV look that gives the tire a more assertive visual presence than a plain black sidewall.
Sidewall appearance will not change the required tire size, but it can noticeably change how the truck presents. Buyers who care about maintaining an off-road-oriented or period truck look often pay close attention to sidewall treatment alongside load capacity, tread style, and wheel compatibility.
What brands offer tires for the 2014 Ford Trucks F-150 FX4?
Current product coverage for the 2014 Ford Trucks F-150 FX4 includes BFGoodrich in 275/65R18. The available tire is the All-Terrain T/A KO2, which places the brand choice within an all-terrain truck tire format rather than a broad mix of unrelated passenger-car styles.
Brand should be considered alongside the tire's actual specifications and intended use, not by name alone. For this FX4 fitment, it makes sense to compare whether the tire matches the truck's wheel width, load needs, driving conditions, and the kind of sidewall appearance the owner wants.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Ford Trucks F-150 FX4?
A period-style choice for a 2014 Ford Trucks F-150 FX4 starts with keeping the truck in its correct radial size and matching the wheel diameter already on the vehicle. That means using 275/55R20 on 20-inch wheels or 275/65R18 on 18-inch wheels, then selecting a tire whose visual character suits the truck's original era.
On a truck from this period, appearance usually comes from sidewall style and overall tire personality rather than from vintage bias-ply details. Raised white letter styling can support a more truck-oriented look, but owners seeking exact presentation should still compare against photos, dealer literature, or marque-specific references.
Does correct tire fitment matter for a 2014 Ford Trucks F-150 FX4 restoration?
Yes, correct tire fitment matters because wheel diameter and tire size are a visible part of how a restored 2014 Ford Trucks F-150 FX4 sits and functions. Using the proper 18-inch or 20-inch fitment helps preserve the truck's intended proportions and avoids turning the restoration into a guesswork tire swap.
Appearance is only part of the equation. Correct fitment also supports proper clearance, load carrying, and predictable road behavior, which becomes especially important on a truck that may have seen wheel changes over the years. Checking the current wheel package before replacing tires is a worthwhile restoration step.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Ford Trucks F-150 FX4?
Yes. A 2014 Ford Trucks F-150 FX4 may no longer match its original setup if it has aftermarket wheels, suspension changes, leveling kits, lowering parts, or body modifications. Those changes can alter the wheel diameter, wheel width, or available clearance around the tire.
That matters even when the sidewall size looks familiar. A tire that belongs on an 18-inch wheel is not interchangeable with one for a 20-inch wheel, and altered offsets or ride height can affect steering and fender clearance. Checking the truck as it sits today is the safest way to avoid a mismatch.
What should I inspect before driving a 2014 Ford Trucks F-150 FX4 on new tires?
Before road use, inspect the wheels for damage, confirm that the tire size matches the wheel diameter, and make sure inflation is set appropriately for the tire and the truck's use. It is also smart to look over suspension and steering components so the new tires are not being asked to work around existing wear.
A careful walkaround afterward is just as important. Check for rubbing at full steering lock, watch for unusual vibration, and recheck pressure after the first stretch of driving. On a truck, early signs of clearance or alignment trouble tend to show up quickly once fresh tires are installed.
How should tires on a 2014 Ford Trucks F-150 FX4 be maintained?
Tires on a 2014 Ford Trucks F-150 FX4 should be maintained with regular pressure checks, routine visual inspections, and attention to tread wear across the full width of the tire. Uneven wear, cuts, bulges, cracking, or repeated air loss are signs that the truck or the tire needs closer inspection.
Longer service life usually depends on catching problems early rather than waiting for a major issue. It helps to inspect the tires before trips, after off-pavement use, and anytime the truck begins to pull, vibrate, or wear tires unevenly. Storage and sun exposure also matter on lightly used trucks.
