The 2013 Ford Trucks F-150 FX4 sits in the modern full-size pickup era where off-road appearance and everyday utility often overlap. As an FX4, tire choice matters not just for look, but for how the truck stands, rides, and clears the wheel openings it was built around. This model uses radial fitments in two sizes, 275/55R20 and 275/65R18, so the first step is confirming which wheel diameter is on the truck. From there, the decision shifts toward maintaining the intended stance and selecting the right tire style for road use, truck duty, or a more aggressive period-appropriate 2010s appearance.
Which Tire Size Is Right for The 2013 Ford Trucks F-150 FX4
The 2013 Ford Trucks F-150 FX4 uses two primary tire sizes, and both are radial fitments. The key difference is wheel diameter: one size is built for an 18-inch rim and the other for a 20-inch rim. Before choosing a tire, confirm which wheels are actually on the truck, since the FX4 Base can use either size and the decision starts with rim diameter rather than construction type.
A 275/55R20 size uses a 275-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2013 Ford Trucks F-150 FX4, this size represents the lower-profile of the two primary fitments and should be matched to the correct 20-inch wheel setup. Its sizing format is familiar to modern truck owners, making comparison straightforward when checking wheel diameter, tire proportions, and overall appearance. This is the size to evaluate when the truck already wears 20-inch wheels and you want to stay with the proper primary fitment format.
A 275/65R18 tire carries a 275-millimeter nominal section width, a 65-series aspect ratio, radial construction, and an 18-inch rim diameter. For the 2013 Ford Trucks F-150 FX4, this size keeps the same basic width as the 20-inch fitment but is built around an 18-inch wheel, so wheel confirmation comes first. Available choices in this size include BFGoodrich with an All Terrain TA KO2 series and raised white letter sidewall styling. It is the right primary size to evaluate when the truck has 18-inch wheels and the buyer wants a truck-oriented radial with a more aggressive visual character.
Fitment is straightforward here because the covered FX4 sub-model uses the same two primary tire sizes already associated with this vehicle. The important step is confirming whether the truck is on 18-inch or 20-inch wheels before narrowing the tire choice.

Best 2013 Ford Trucks F-150 FX4 Tires for Sale
Current product choices for the 2013 Ford Trucks F-150 FX4 center on the 275/65R18 size, including a BFGoodrich All Terrain TA KO2 radial with raised white letter sidewall styling. That gives buyers a useful comparison point for truck-focused appearance, rim-width compatibility, and load-carrying specification.
Owners of a 2013 Ford Trucks F-150 FX4 usually need to confirm tire size by wheel diameter first, then sort through radial fitment, product selection, appearance, and road-use checks. These questions focus on the details that matter most when replacing tires on this exact truck.
Tire Size & Fitment
What tire size fits a 2013 Ford Trucks F-150 FX4?
The 2013 Ford Trucks F-150 FX4 uses two primary tire sizes: 275/55R20 and 275/65R18. Both are radial tire sizes, and the difference between them is tied mainly to wheel diameter, with one built for a 20-inch rim and the other for an 18-inch rim.
Choosing the right one starts with checking the wheels actually on the truck. Even within the FX4 Base sub-model, either size may apply, so the correct choice is not based on guesswork or appearance alone. Confirm the wheel diameter stamped on the rim or read the current tire size before comparing replacement tires.
What size rim does a 2013 Ford Trucks F-150 FX4 use?
A 2013 Ford Trucks F-150 FX4 can use either an 18-inch rim or a 20-inch rim, depending on which primary tire size is on the truck. The 275/65R18 tire is built for an 18-inch wheel, while the 275/55R20 tire is built for a 20-inch wheel.
That makes rim diameter the first fitment check before selecting replacement tires. A tire made for an 18-inch wheel cannot be mounted on a 20-inch wheel, and the reverse is equally true. If the truck has had wheel changes over the years, inspect the actual wheel size rather than assuming it still matches its original setup.
Does the 2013 Ford Trucks F-150 FX4 Base use the same tire size?
The 2013 Ford Trucks F-150 FX4 Base is associated with both primary tire sizes used for this model: 275/55R20 and 275/65R18. That means the sub-model name alone does not narrow the truck down to one single tire size without first confirming the wheel package on the vehicle.
In practical terms, the next step is to verify whether the truck is riding on 18-inch or 20-inch wheels. Once that is confirmed, tire selection becomes much simpler because both fitments are radial and use the same basic sizing format. Any wheel swap, aftermarket package, or previous owner change makes this check especially important.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Ford Trucks F-150 FX4?
Start with the correct primary size for the wheel diameter on the truck: 275/55R20 for 20-inch rims or 275/65R18 for 18-inch rims. Since both fitments are radial, the decision usually comes down to matching the wheel size first, then comparing tire type, sidewall style, rim-width compatibility, and load specification.
A truck used mainly on pavement may call for different priorities than one that sees dirt roads, weather, or heavier-duty use. It also helps to compare how the tire will look on the truck, especially if raised white letters or a more aggressive tread style matter. Keeping the correct size and checking wheel compatibility should stay ahead of appearance alone.
What sidewall styles are available for 2013 Ford Trucks F-150 FX4 tires?
Available product selection for the 2013 Ford Trucks F-150 FX4 includes an RWL sidewall in the 275/65R18 size. RWL stands for raised white letter, a style that gives the truck a more assertive off-road and light-truck look than a plain blackwall presentation.
Sidewall style does not change the need to match the correct size and wheel diameter. On a truck like the FX4, appearance can be a meaningful part of the decision, especially if the goal is to preserve a bold 2010s truck character. Still, the sidewall treatment should be considered after confirming the proper fitment and intended use.
What brands offer tires for the 2013 Ford Trucks F-150 FX4?
BFGoodrich is available for the 2013 Ford Trucks F-150 FX4 in the 275/65R18 size. The offered product is from the All Terrain TA KO2 series, which gives buyers a clearly truck-oriented option within one of the FX4's primary fitments.
Brand should be compared alongside size, wheel compatibility, sidewall style, and how the truck is actually driven. On a fitment page this specific, the more useful question is not simply who makes the tire, but whether the available product suits the wheel setup and the truck's mix of road use, utility, and visual preference.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Ford Trucks F-150 FX4?
A period-style approach for a 2013 Ford Trucks F-150 FX4 starts with staying in the correct primary size for the wheel diameter already on the truck, either 275/55R20 or 275/65R18. Because this is a modern truck-era fitment, the most authentic overall presentation usually comes from preserving the proper size relationship between tire and wheel.
For owners who want a stronger truck and off-road visual character, an all-terrain style and sidewall treatment can shape the look as much as the size itself. Any appearance-driven choice still needs to respect actual wheel dimensions and the truck's current setup. That keeps the finished look believable without creating avoidable fitment issues.
How does tire construction affect the appearance of a restored 2013 Ford Trucks F-150 FX4?
Construction is less of a visual dividing line here because the 2013 Ford Trucks F-150 FX4 uses radial primary fitments in both sizes. The truck's appearance is influenced more by wheel diameter, tire profile, sidewall treatment, and tread style than by any choice between bias-ply and radial construction.
That makes size and presentation the more important restoration-style decisions. A 20-inch setup and an 18-inch setup can give the truck a different stance, even when overall proportions remain close. Buyers aiming for a clean era-appropriate look should confirm the existing wheel package first, then choose a tire whose sidewall and tread character match the truck's intended personality.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Ford Trucks F-150 FX4?
Yes. Wheel swaps, suspension changes, leveling kits, lowering, and other modifications can affect tire fitment on a 2013 Ford Trucks F-150 FX4 even when the tire size looks close to stock. The truck already uses two different wheel diameters, so any change to the wheel or suspension package can alter clearance and tire selection.
A modified truck should be checked for actual wheel diameter, wheel width, steering clearance, and space at the fenders before replacement tires are chosen. It is also smart to inspect for rubbing marks or uneven wear on the current tires. Those clues often reveal whether the present setup is working well or already pushing the available space.
What should I inspect before driving a 2013 Ford Trucks F-150 FX4 on new tires?
Before road use, inspect the wheels for the correct diameter and any visible damage, then confirm the tires are the proper size for the truck's setup. Check inflation pressure, look over the sidewalls and tread for cuts or defects, and make sure each tire has adequate clearance at full steering lock.
A brief inspection drive is worthwhile after installation. Pay attention to vibration, pull, rubbing, or unusual steering feel, since those can point to balance issues, alignment concerns, or a mismatch between the wheel and tire package. On a truck that may see work, weather, or rougher surfaces, catching those problems early matters more than simply mounting the tires and heading out.
How often should tires on a 2013 Ford Trucks F-150 FX4 be inspected?
Tires on a 2013 Ford Trucks F-150 FX4 should be inspected regularly, not just when replacement time arrives. A quick visual check before longer trips and routine pressure checks between services help catch tread wear, sidewall damage, punctures, and gradual air loss before those issues become more serious.
The inspection schedule should become even more consistent if the truck is used for hauling, sees rough roads, or spends stretches parked outdoors. Irregular wear can also point to alignment, suspension, or wheel issues that affect more than tire life alone. Keeping an eye on condition and pressure is one of the simplest ways to protect fitment and road manners.
