The 2013 Ford Trucks F-150 STX sits in the modern full-size pickup era, when buyers expected a truck to handle daily driving, weekend hauling, and rougher back-road use without giving up everyday comfort. The STX package also tends to attract owners who want a cleaner, sportier look while keeping the F-150’s practical character intact. Tire fitment for the 2013 Ford Trucks F-150 STX is fully radial, with four primary sizes tied to 17-inch and 18-inch wheel setups. Available choices center on modern metric truck sizing and BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls. The real key is confirming whether the truck is a 4x2 or 4x4 and matching the tire to the actual wheel diameter.
Which Tire Size Is Right for The 2013 Ford Trucks F-150 STX
The 2013 Ford Trucks F-150 STX uses four primary tire sizes, and the right one depends first on whether the truck is a 4x2 or 4x4, then on whether it has 17-inch or 18-inch wheels. All four fitments are radial metric sizes, so the decision is less about vintage construction and more about matching the truck’s exact setup, wheel diameter, and intended use.
255/65R17 is a metric radial size in which 255 identifies the section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2013 Ford Trucks F-150 STX, this size is one of the 4x2 fitments and keeps the truck in a modern light-truck sizing format. Product choice here centers on the BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. This size is worth considering when the truck is already set up with 17-inch wheels and the goal is to stay with the correct 4x2 fitment range.
265/60R18 is a metric radial size that uses a 265-millimeter nominal section width, a 60-series profile, and an 18-inch rim diameter. For the 2013 Ford Trucks F-150 STX, this size belongs to the 4x2 side of the fitment range and should be chosen only after confirming that the truck actually carries 18-inch wheels. Its lower-profile format compared with the 17-inch 4x2 option makes wheel verification especially important before selecting a tire. This size matters most when preserving the truck’s existing 18-inch setup rather than switching diameters.
265/70R17 is a metric radial size with a 265-millimeter section width, a 70-series profile, radial construction, and a 17-inch wheel diameter. On the 2013 Ford Trucks F-150 STX, it is one of the 4x4 fitments and sits within the truck’s larger-duty side of the size range. Available products include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls, including versions with different load capacities and inflation figures. This size deserves a careful look when the truck is a 4x4 on 17-inch wheels and the buyer wants to compare specification differences within the same basic tire family.
275/65R18 is a metric radial size in which 275 gives the nominal section width in millimeters, 65 is the aspect ratio, and 18 identifies the wheel diameter. For the 2013 Ford Trucks F-150 STX, this is the larger 18-inch fitment used on 4x4 trucks, so it should not be treated as a general-size substitute across the entire STX lineup. BFGoodrich offers this size in the All-Terrain T/A KO2 series with raised white letter sidewalls. It is the size to evaluate when the truck is already equipped with 18-inch 4x4 wheels and the goal is to stay within that specific configuration.
Fitment changes across the 2013 Ford Trucks F-150 STX lineup, so sub-model identification matters before anything else. The main split is between 4x2 and 4x4 trucks, and each can use either a 17-inch or 18-inch wheel-based tire size.

2013 Ford Trucks F-150 STX 4x2
The 2013 Ford Trucks F-150 STX 4x2 uses radial metric sizing with a choice tied to either 17-inch or 18-inch wheels. Tire selection starts with confirming the actual wheel diameter on the truck, then choosing the right metric size for that setup rather than assuming every STX uses the same fitment.
The 2013 Ford Trucks F-150 STX 4x4 uses larger radial metric fitments than the 4x2, again split between 17-inch and 18-inch wheel diameters. That makes wheel confirmation especially important before comparing tires, since the correct size depends on the truck’s exact 4x4 configuration and wheel package.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2013 Ford Trucks F-150 STX Tires for Sale
Available product choices for the 2013 Ford Trucks F-150 STX center on BFGoodrich All-Terrain T/A KO2 tires in select 17-inch and 18-inch metric sizes. The main comparisons involve raised white letter sidewalls, rim-width range, load capacity, and size-specific fitment within the STX lineup.
Tire questions for the 2013 Ford Trucks F-150 STX usually come down to exact size, 4x2 versus 4x4 fitment, 17-inch versus 18-inch wheels, and choosing the right radial tire for the truck’s intended use.
Tire Size & Fitment
What tire size fits a 2013 Ford Trucks F-150 STX?
The 2013 Ford Trucks F-150 STX uses four possible tire sizes: 255/65R17, 265/60R18, 265/70R17, and 275/65R18. The 4x2 sub-model uses 255/65R17 or 265/60R18, while the 4x4 sub-model uses 265/70R17 or 275/65R18.
The first step is identifying whether the truck is a 4x2 or 4x4, then confirming whether it has 17-inch or 18-inch wheels. That matters more than comparing sizes by appearance alone, because the STX fitment range spans two driveline configurations and two rim diameters.
What size rim does a 2013 Ford Trucks F-150 STX use?
A 2013 Ford Trucks F-150 STX uses either a 17-inch or 18-inch rim, depending on the tire size and sub-model setup. The 17-inch fitments are 255/65R17 and 265/70R17, while the 18-inch fitments are 265/60R18 and 275/65R18.
Wheel diameter has to match the tire exactly, so a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. Before choosing a replacement tire, check the actual wheel on the truck, especially if it has had wheels changed at some point in its service life.
Why does the 2013 Ford Trucks F-150 STX have more than one tire size?
The 2013 Ford Trucks F-150 STX has more than one tire size because fitment changes by sub-model and wheel package. The 4x2 and 4x4 versions do not share the same size range, and each can be paired with either a 17-inch or 18-inch wheel diameter.
That means the correct tire is tied to the truck’s exact configuration rather than the STX badge alone. A replacement decision should start with the sub-model, then the installed wheel diameter, and finally the exact size already on the truck if originality to its current setup matters.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Ford Trucks F-150 STX?
Start with the correct size for the truck’s exact setup, since the 2013 Ford Trucks F-150 STX uses four different radial sizes across 4x2 and 4x4 configurations. After size is confirmed, compare wheel diameter, rim-width compatibility, load capacity, and the type of use the truck will see.
A truck used mainly on pavement may be approached differently than one that regularly sees gravel, jobsite, or trail conditions. It also helps to look at the actual wheel currently installed, because a changed wheel package can matter just as much as the original 4x2 or 4x4 configuration.
What sidewall styles are available for 2013 Ford Trucks F-150 STX tires?
The available products for the 2013 Ford Trucks F-150 STX use RWL sidewalls, which means raised white letter styling. That gives the truck a more traditional light-truck look than a plain blackwall and is part of the overall character of the available BFGoodrich all-terrain options.
Sidewall style does not change the basic fitment, but it does affect the truck’s visual presentation. Owners trying to keep an STX looking rugged and era-appropriate often pay close attention to that detail, especially when replacing only one axle set or trying to match an existing tire appearance.
What tire series are available for the 2013 Ford Trucks F-150 STX?
The available series for the covered 2013 Ford Trucks F-150 STX tire sizes is the BFGoodrich All-Terrain T/A KO2. That puts the current product selection squarely in an all-terrain, radial truck-tire category rather than a highway-only or vintage-style assortment.
Because the series is consistent, the main selection differences shift to size, rim-width range, and load-capacity specification within each fitment. That is especially relevant in 265/70R17, where more than one KO2 specification is available and the buyer should compare the tire to the truck’s actual use requirements.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Ford Trucks F-150 STX?
A period-style choice for a 2013 Ford Trucks F-150 STX starts with keeping the correct size for the truck’s 4x2 or 4x4 configuration and its 17-inch or 18-inch wheels. Since the available products are modern radial all-terrain tires, the visual character comes more from proper sizing and sidewall treatment than from vintage construction decisions.
Raised white letter sidewalls can help preserve the look many owners associate with full-size trucks of this era. The most convincing result usually comes from matching the truck’s existing wheel setup cleanly, avoiding unnecessary size changes, and keeping front and rear tire presentation consistent.
Does correct tire fitment matter for a 2013 Ford Trucks F-150 STX restoration?
Correct tire fitment matters on a 2013 Ford Trucks F-150 STX because size choice affects both appearance and how properly the truck sits on its wheels. A 4x2 STX and a 4x4 STX do not share the same size range, so using the wrong tire can make the truck look mismatched even before road behavior is considered.
Restoration-minded owners usually get the best result by confirming the truck’s exact sub-model and wheel diameter before selecting tires. For buyers who want the closest visual match to a specific original delivery configuration, vehicle records, window-sticker documentation, or marque-specific references are still worth checking.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Ford Trucks F-150 STX?
Yes, modifications can affect tire fitment on a 2013 Ford Trucks F-150 STX even when the tire size itself is correct for an STX configuration. Changes to wheels, wheel width, offset, ride height, suspension components, or front-end geometry can alter clearance and how the tire sits in the wheel opening.
A truck with aftermarket wheels or a leveling or lowering change should be checked carefully before replacing tires by size name alone. Steering clearance, fender clearance, and the actual wheel dimensions matter, especially because this STX lineup already spans both 17-inch and 18-inch fitments.
What should I inspect before driving a 2013 Ford Trucks F-150 STX on new tires?
Before driving a 2013 Ford Trucks F-150 STX on new tires, inspect the wheels for damage, confirm the tire size matches the installed rim diameter, and verify proper inflation for the chosen tire. It is also wise to look over valve stems, lug hardware, and general tread and sidewall condition on any existing tire being kept in service.
A short clearance check at full steering lock can prevent surprises after installation. On a truck that sees heavier use, it also helps to pay attention to uneven wear, alignment condition, and suspension play, since those issues can shorten tire life even when the replacement size is correct.
How should tires on a 2013 Ford Trucks F-150 STX be maintained?
Tires on a 2013 Ford Trucks F-150 STX should be maintained with regular pressure checks, routine inspection for cuts or punctures, and close attention to tread wear across the full width of the tire. Because these are truck fitments, owners should also stay aware of load demands and not overlook sidewall condition.
Consistent maintenance is especially important when the truck is used for mixed street and light off-road service, where impacts and uneven surfaces can accelerate wear. Trucks that sit for long periods still deserve inspection for air loss, cracking, and age-related deterioration before being returned to regular road use.
