The 2012 Ford Trucks F-250 Super Duty sits squarely in the modern heavy-duty pickup era, where towing ability, work-truck durability, and off-pavement confidence all shape tire choice. Buyers looking at this exact truck are usually balancing trim level, drivetrain, and wheel package just as much as tread style. Tire fitment spans five radial sizes, from 17-inch applications like 245/75R17 and 265/70R17 up to 18- and 20-inch sizes including 275/65R18, 275/70R18, and 275/65R20. Available choices lean toward BFGoodrich All-Terrain T/A KO2 products with raised white letter or raised black letter presentations. The key is confirming the truck's exact sub-model and wheel diameter before comparing load capacity, rim-width compatibility, and appearance.
Which Tire Size Is Right for The 2012 Ford Trucks F-250 Super Duty
Five tire sizes apply to the 2012 Ford Trucks F-250 Super Duty, and they vary by sub-model, drivetrain, option package, and wheel diameter. Some versions use 17-inch wheels, others use 18-inch or 20-inch wheels, so the first step is confirming the exact sub-model and actual rim diameter on the truck. Once that is settled, the decision shifts to choosing the right radial size with the appropriate load capacity, rim-width range, and sidewall presentation.
275/65R18 is a metric radial size in which 275 identifies nominal section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2012 Ford Trucks F-250 Super Duty, this size serves specific 18-inch applications rather than every configuration. In this size, BFGoodrich offers the All-Terrain T/A KO2 with a raised white letter sidewall. It is a useful choice for trucks that need the correct 18-inch fitment while keeping an all-terrain tire profile and heavy-duty load capability in view.
Fit(s): King Ranch 4x4, Lariat (20 Inch Option), and XLT (20 Inch Option)
Construction: Radial|Rim: 20 in
275/65R20 follows the same metric radial format, with a 275-millimeter nominal section width, a 65-series profile, radial construction, and a 20-inch rim diameter. This size belongs to certain 20-inch F-250 Super Duty configurations, so wheel diameter must be confirmed before treating it as an option. BFGoodrich offers this size in the All-Terrain T/A KO2 series with a raised black letter sidewall treatment. Buyers considering this fitment should focus on matching the truck's wheel package and intended use rather than assuming every upscale or optioned model uses the same tire.
275/70R18 is a metric radial size with a 275-millimeter nominal section width, a 70-series aspect ratio, and an 18-inch wheel diameter. It appears on selected 18-inch versions of the 2012 Ford Trucks F-250 Super Duty, particularly where the truck is set up differently from 17-inch or 20-inch packages. BFGoodrich lists this size in the All-Terrain T/A KO2 series with a raised white letter sidewall. This fitment is worth evaluating carefully when the truck already has 18-inch wheels and the buyer wants to stay with the proper diameter, radial construction, and all-terrain character.
245/75R17 is a metric radial size where 245 is the nominal section width in millimeters, 75 is the aspect ratio, R means radial, and 17 is the wheel diameter in inches. On the 2012 Ford Trucks F-250 Super Duty, it covers several 17-inch applications, especially in XL and some XLT configurations. BFGoodrich offers this size in the All-Terrain T/A KO2 line with a raised white letter sidewall. It is an important fitment to keep separate from the wider 265/70R17, since both share a 17-inch rim diameter but do not represent the same specification.
265/70R17 is a metric radial size with a 265-millimeter nominal section width, a 70-series profile, and a 17-inch rim diameter. This size applies to certain 17-inch F-250 Super Duty configurations, including some all-terrain and 4x4 applications, so it should not be assumed for every 17-inch truck. BFGoodrich offers the All-Terrain T/A KO2 in this size with a raised white letter sidewall, and two load-capacity versions are available. That makes this size especially important to verify against the truck's exact setup and expected working load before making a final selection.
Sub-model fitment on the 2012 Ford Trucks F-250 Super Duty is not one-size-fits-all. Tire choice depends on the exact trim, drivetrain, and wheel package, with 17-inch, 18-inch, and 20-inch applications all appearing across the lineup.

2012 Ford Trucks F-250 Super Duty King Ranch 4x2
The King Ranch 4x2 uses a single 18-inch tire fitment, which keeps selection relatively straightforward once the truck's wheel setup is confirmed. The main task here is choosing the right radial tire within that size and matching its load and rim-width specifications to the truck's intended use.
The King Ranch 4x4 can use either an 18-inch or 20-inch tire fitment, making wheel diameter the first thing to verify on the truck itself. Once that is settled, tire selection becomes a comparison between the correct radial size, sidewall presentation, and the load specification that best suits the truck.
2012 Ford Trucks F-250 Super Duty Lariat (20 Inch Option)
The Lariat with the 20 Inch Option uses a dedicated 20-inch tire setup, so the fitment path is tied closely to the wheel package already on the truck. Tire selection should stay focused on the correct radial size and on confirming that the wheel width and load requirements match the replacement tire.
The Lariat 4x2 uses an 18-inch tire fitment that differs from some 17-inch and 20-inch F-250 configurations. That makes wheel confirmation important before comparing available radial choices, especially if the truck has seen wheel or suspension changes over time.
The Lariat 4x4 uses a 275/70R18 radial fitment, putting it in the 18-inch group rather than the 17-inch or 20-inch setups found elsewhere in the range. Tire selection here should center on keeping the correct 18-inch size while checking rim-width compatibility and the truck's actual working demands.
The XL 4x2 uses a 17-inch radial tire size, which separates it from the wider 18-inch and 20-inch applications found on other F-250 trims. For replacement, the focus should be on staying with the proper 17-inch specification and confirming that the wheel setup still matches the intended tire.
2012 Ford Trucks F-250 Super Duty XL 4x2 (All-Terrain Tires)
The XL 4x2 with All-Terrain Tires can use either of two 17-inch sizes, so the exact tire already on the truck matters before making a selection. This is a case where reading the current sidewall and confirming wheel width can prevent choosing the wrong radial specification.
The XL 4x4 uses a 17-inch radial fitment and should be matched to that wheel diameter before comparing any replacement tire. A careful check of the current wheel and tire combination is especially worthwhile on work trucks that may have been altered for service use.
2012 Ford Trucks F-250 Super Duty XL 4x4 (All-Terrain Tires)
The XL 4x4 with All-Terrain Tires can use two different 17-inch sizes, so the selection process starts with identifying which size is actually on the truck. From there, the buyer can compare radial choices by load specification, rim-width range, and the overall all-terrain setup.
2012 Ford Trucks F-250 Super Duty XLT (20 Inch Option)
The XLT with the 20 Inch Option uses a 20-inch tire fitment that is distinct from the 17-inch and 18-inch arrangements elsewhere in the F-250 line. Replacement should stay centered on the correct 20-inch radial size and on verifying wheel width and service demands before moving ahead.
The XLT 4x2 can use either a 17-inch or 18-inch tire fitment, so the actual wheel diameter is more important than the trim name alone. Tire selection only becomes straightforward after confirming which setup the truck carries, especially on vehicles that may have had wheel-package changes.
2012 Ford Trucks F-250 Super Duty XLT 4x2 (All-Terrain Tires)
The XLT 4x2 with All-Terrain Tires uses one of two 17-inch radial sizes, which means the buyer needs to confirm the exact specification on the truck first. That check helps separate a standard 17-inch fitment from the wider all-terrain alternative before comparing product details.
The XLT 4x4 can use either a 17-inch or 18-inch radial tire size, so there is no substitute for checking the truck's actual wheel and tire combination. Once identified, the right replacement choice comes down to staying with the proper diameter and matching the tire's load and width specifications.
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 2012 Ford Trucks F-250 Super Duty Tires for Sale
Available 2012 Ford Trucks F-250 Super Duty tire choices center on BFGoodrich All-Terrain T/A KO2 products across the five supported radial sizes. The main comparison points are wheel diameter, rim-width range, load capacity, and sidewall presentation, with raised white letter styles appearing most often and a raised black letter option in 275/65R20.
Tire questions for the 2012 Ford Trucks F-250 Super Duty usually come down to identifying the correct size by sub-model and wheel package, then comparing radial tire specifications, sidewall style, and load capacity for real truck use.
Tire Size & Fitment
What tire size fits a 2012 Ford Trucks F-250 Super Duty?
The 2012 Ford Trucks F-250 Super Duty uses five possible tire sizes: 245/75R17, 265/70R17, 275/65R18, 275/70R18, and 275/65R20. All of them are radial sizes, but they do not apply across the entire lineup because fitment changes with trim, drivetrain, all-terrain package, and wheel option.
The practical first step is identifying the truck's exact sub-model and confirming whether it carries 17-inch, 18-inch, or 20-inch wheels. Two trucks with the same model name can still require different tires, so checking the current sidewall size and the wheel itself is the safest way to narrow the choice.
What size rim does a 2012 Ford Trucks F-250 Super Duty use?
A 2012 Ford Trucks F-250 Super Duty can use 17-inch, 18-inch, or 20-inch rims, depending on the exact configuration. The supported tire sizes match those diameters directly: 245/75R17 and 265/70R17 use 17-inch rims, 275/65R18 and 275/70R18 use 18-inch rims, and 275/65R20 uses a 20-inch rim.
That makes wheel diameter the first thing to verify before comparing tires. Looking only at trim level is not always enough, since some sub-models carry multiple possible wheel and tire combinations. A quick check of the wheel size or the existing tire code can prevent ordering a correct tire size for the wrong rim diameter.
Why does the 2012 Ford Trucks F-250 Super Duty have more than one tire size?
Multiple tire sizes appear because the 2012 Ford Trucks F-250 Super Duty was offered in several trims, drivetrains, and wheel-option combinations. XL, XLT, Lariat, and King Ranch versions do not all share the same setup, and some all-terrain or 20-inch packages change the original fitment further.
That variation means tire selection starts with the exact truck, not just the year and model family. An XLT 4x2, an XL 4x4, and a King Ranch 4x4 can lead to different size paths, so the buyer should confirm the sub-model and actual wheels before comparing tread pattern, load capacity, or sidewall style.
Choosing the Right Tire
What should I consider when choosing a tire for a 2012 Ford Trucks F-250 Super Duty?
Start with the correct tire size for the truck's exact sub-model and wheel diameter, since this F-250 Super Duty uses five different radial sizes. After size is confirmed, compare the tire's rim-width range, load capacity, and whether the truck's use leans more toward highway duty, towing, or all-terrain work.
Appearance can matter too, especially when sidewall style differs between sizes. Some supported options use raised white letters, while 275/65R20 is available with a raised black letter presentation. Matching the truck's current wheel setup and expected service is more important than choosing by trim name alone.
What sidewall styles are available for 2012 Ford Trucks F-250 Super Duty tires?
Sidewall style varies by size on the 2012 Ford Trucks F-250 Super Duty. Raised white letter sidewalls appear on 245/75R17, 265/70R17, 275/65R18, and 275/70R18 BFGoodrich All-Terrain T/A KO2 tires, while 275/65R20 is offered with a raised black letter sidewall.
That means sidewall appearance is tied to the tire size and wheel package, not simply to personal preference. Buyers trying to maintain a particular look should confirm the truck's actual fitment first, then compare whether the available sidewall treatment suits a work-oriented, off-road, or cleaner street presentation.
What brands offer tires for the 2012 Ford Trucks F-250 Super Duty?
BFGoodrich is the brand available across the supported 2012 Ford Trucks F-250 Super Duty tire sizes here, with the All-Terrain T/A KO2 series covering 17-inch, 18-inch, and 20-inch applications. In 265/70R17, two load-capacity versions are available within that same series.
Since the brand and series stay consistent, the meaningful comparison shifts to size, sidewall style, rim-width specification, and load figure at the stated inflation pressure. That is especially important on a heavy-duty truck, where the right version within the correct size can matter as much as the tread design itself.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Ford Trucks F-250 Super Duty?
A period-style choice for a 2012 Ford Trucks F-250 Super Duty starts with the exact original-type size for that truck's trim and wheel package, whether that is a 17-inch, 18-inch, or 20-inch radial application. Staying with the correct size preserves the truck's stance and keeps the look consistent with how that configuration was equipped.
From there, sidewall treatment becomes the visual detail that most owners notice first. Raised white letter and raised black letter presentations create different looks even within the same all-terrain family. For buyers pursuing a highly exact appearance, truck-specific sales literature or marque documentation can help confirm what best suits the vehicle.
How does tire construction affect the appearance of a restored 2012 Ford Trucks F-250 Super Duty?
Construction is simple on the 2012 Ford Trucks F-250 Super Duty because the supported fitments here are all radial tires. That means the visual differences are less about bias-ply versus radial shape and more about the actual tire size, sidewall lettering style, and how the chosen wheel diameter fills the truck's wheel openings.
A 17-inch setup presents differently from an 18-inch or 20-inch package, even before tread details are considered. Buyers aiming for a restoration-oriented or stock-type appearance should match the truck's exact trim and wheel configuration first, then choose the sidewall style that best complements that setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Ford Trucks F-250 Super Duty?
Yes, modifications can change tire fitment on a 2012 Ford Trucks F-250 Super Duty even when the tire size is correct for a stock configuration. Aftermarket wheels, suspension lifts, leveling kits, lowering changes, or different offsets can alter clearance around the fenders, steering components, and suspension parts.
That is why the actual wheel diameter and width on the truck should be confirmed before replacement. A tire that matches the original size code still needs to suit the current setup. Clearance through the full steering range and under load is worth checking carefully on any truck that no longer carries its original wheel package.
What should I inspect before driving a 2012 Ford Trucks F-250 Super Duty on new tires?
Before road use, inspect tire pressure, lug torque, valve stems, and overall tire condition, then confirm that the new tires match the truck's correct size and rim diameter. It is also wise to check for visible rubbing at the fenders and suspension, especially if the F-250 has different wheels or any ride-height changes.
A heavy-duty truck should also be checked for uneven wear patterns that may point to alignment or suspension issues. New tires can only do their job properly if the steering and suspension are in sound condition. Taking a short test drive and rechecking pressure and clearance afterward is a sensible final step.
How often should tires on a 2012 Ford Trucks F-250 Super Duty be inspected?
Tires on a 2012 Ford Trucks F-250 Super Duty should be inspected regularly, not just at replacement time. Pressure, tread wear, sidewall condition, and any signs of cuts, bulges, or irregular wear deserve routine attention, particularly on a truck that tows, carries weight, or sees rougher road and trail use.
A quick visual check before longer drives is a good habit, and low-use trucks still need inspection because age and storage conditions matter too. Trucks that sit for long periods can develop pressure loss or sidewall deterioration even with low mileage, so calendar time is nearly as important as miles traveled.
