The 2011 Ford Trucks F-350 Super Duty XLT sits in the heavy-duty pickup world where towing, payload, and four-season road use put real demands on tire choice. In this generation, the Super Duty balanced work-truck capability with trim-level comfort, so tire fitment matters as much for function as appearance. This exact model uses several primary radial sizes, including 17-, 18-, and 20-inch applications depending on configuration. Available choices center on BFGoodrich All-Terrain T/A KO2 tires, with sidewall treatments that vary by size. The key step is matching the truck's exact sub-model and wheel diameter before comparing load-related specifications, sidewall style, and intended use.
Which Tire Size Is Right for The 2011 Ford Trucks F-350 Super Duty XLT
The 2011 Ford Trucks F-350 Super Duty XLT uses five primary tire sizes, and the right one depends on the truck's exact sub-model and wheel diameter. These are all radial fitments, but they span 17-, 18-, and 20-inch rims, so confirming the truck's actual wheel setup comes first. Once that is settled, the decision shifts to the tire's load-related specification, sidewall presentation, and how the truck is used on pavement or mixed terrain.
275/65R20 is a metric radial size in which 275 indicates section width in millimeters, 65 is the aspect ratio, R designates radial construction, and 20 is the rim diameter in inches. On the 2011 Ford Trucks F-350 Super Duty XLT, this size belongs to the 20 Inch Option and is tied to a larger wheel package rather than the full range of XLT configurations. Available choices in this size include a BFGoodrich All-Terrain T/A KO2 with an RBL sidewall. It is a useful fitment to evaluate when the truck already carries 20-inch wheels and the goal is to preserve that wheel-and-tire setup.
Fit(s): 4x2, 4x2 (All-Terrain Tires), 4x2 (DRW), and 4x4 (DRW)
Construction: Radial|Rim: 17 in
245/75R17 is a metric radial size with a 245-millimeter section width, a 75-series profile, radial construction, and a 17-inch rim requirement. This size appears across several 2011 Ford Trucks F-350 Super Duty XLT configurations, including 4x2, 4x2 DRW, and 4x4 DRW applications, making it one of the more common fitments within the model range. In the available products, it comes as a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is the size to focus on when the truck uses a 17-inch wheel and the configuration calls for the narrower metric fitment.
275/65R18 is a metric radial designation where 275 is the width in millimeters, 65 is the aspect ratio, R marks radial construction, and 18 identifies the wheel diameter. For the 2011 Ford Trucks F-350 Super Duty XLT, this size is used on certain 4x2 configurations and reflects an 18-inch wheel package rather than the whole XLT lineup. The available product in this fitment is a BFGoodrich All-Terrain T/A KO2 with raised white letters. This size deserves attention when the truck is equipped with 18-inch wheels and the owner wants to compare load-related tire details within that original wheel diameter.
265/70R17 is a metric radial size that combines a 265-millimeter section width, a 70-series profile, radial construction, and a 17-inch rim. On the 2011 Ford Trucks F-350 Super Duty XLT, it appears on certain 4x4 and 4x2 All-Terrain Tire configurations, so it should not be treated as universal across every XLT. This size has more than one BFGoodrich All-Terrain T/A KO2 option, both with raised white letter sidewalls, and the available versions differ in load-related specification and product weight. It is worth checking closely when a 17-inch-wheel truck needs the wider all-terrain-oriented fitment rather than the 245-section alternative.
275/70R18 is a metric radial code in which 275 gives the tire width in millimeters, 70 indicates the aspect ratio, R means radial, and 18 is the required wheel diameter. This size is used on certain 4x4 versions of the 2011 Ford Trucks F-350 Super Duty XLT and is associated with an 18-inch setup that differs from both the 17-inch and 20-inch applications. The available product is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is the right size to investigate when the truck has the 18-inch 4x4 arrangement and the owner wants to stay aligned with that specific configuration.
2011 Ford Trucks F-350 Super Duty XLT Sub-Model Tires
Tire fitment for the 2011 Ford Trucks F-350 Super Duty XLT varies by sub-model, drivetrain, wheel option, and certain package differences. Checking the exact XLT configuration matters because this truck can use more than one tire size and more than one rim diameter depending on how it was equipped.

2011 Ford Trucks F-350 Super Duty XLT (20 Inch Option)
The 20 Inch Option uses the 275/65R20 radial fitment, which separates it immediately from the 17-inch and 18-inch XLT setups. Tire selection here starts with confirming that the truck still has its 20-inch wheels, then comparing the available all-terrain product and sidewall presentation within that size.
The 4x2 configuration can use either a 245/75R17 or a 275/65R18 radial tire, so wheel diameter must be verified before choosing a replacement. Once the correct rim size is confirmed, the decision becomes a matter of matching the truck's existing setup and reviewing the available tire specifications in that size.
2011 Ford Trucks F-350 Super Duty XLT 4x2 (All-Terrain Tires)
The 4x2 All-Terrain Tires version uses 17-inch radial fitments, but it can be equipped with either 245/75R17 or 265/70R17. That makes it important to check the current wheel-and-tire combination on the truck rather than assuming every 4x2 XLT uses the same section width.
The 4x2 DRW version uses the 245/75R17 radial size, giving this sub-model a more straightforward fitment path than the multi-size single-rear-wheel setups. Tire selection should still include a close look at wheel compatibility and the load-related specification of the available 17-inch tire.
The 4x4 configuration can use either 265/70R17 or 275/70R18 radial tires, so this sub-model requires both configuration and wheel-diameter confirmation. That distinction affects more than appearance, since the correct tire choice depends on staying with the truck's actual 17-inch or 18-inch wheel setup.
The 4x4 DRW version uses the 245/75R17 radial tire size, which keeps fitment simpler than the multi-size 4x4 single-rear-wheel configuration. The main task is confirming the truck still carries the proper 17-inch wheel setup and then selecting the tire that matches its intended road and work use.
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 2011 Ford Trucks F-350 Super Duty XLT Tires for Sale
Available tires for the 2011 Ford Trucks F-350 Super Duty XLT center on BFGoodrich All-Terrain T/A KO2 radial fitments across all five sizes. Depending on size, the comparison points include RWL or RBL sidewall styling, rim-width range, weight, and load capacity at the stated pressure.
Common questions for the 2011 Ford Trucks F-350 Super Duty XLT usually come down to identifying the right tire size for the exact configuration, confirming wheel diameter, and comparing available radial tire choices for work, mixed-terrain use, and long-term truck maintenance.
Tire Size & Fitment
What tire size fits a 2011 Ford Trucks F-350 Super Duty XLT?
The 2011 Ford Trucks F-350 Super Duty XLT can use 275/65R20, 245/75R17, 275/65R18, 265/70R17, or 275/70R18, depending on the exact sub-model and wheel package. All of these are radial tire sizes, but they are not interchangeable primary fitments across the entire XLT range.
The first thing to confirm is the truck's exact configuration, including whether it is 4x2, 4x4, DRW, or equipped with the 20-inch option. Checking the current wheel diameter on the truck is just as important, since this model uses 17-, 18-, and 20-inch applications and the correct replacement begins with matching that wheel size.
What size rim does a 2011 Ford Trucks F-350 Super Duty XLT use?
A 2011 Ford Trucks F-350 Super Duty XLT can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model and option package. The tire sizes tied to those wheels are 245/75R17 or 265/70R17 on 17-inch rims, 275/65R18 or 275/70R18 on 18-inch rims, and 275/65R20 on 20-inch rims.
That makes wheel confirmation a necessary step before ordering replacement tires. The easiest way to avoid a mismatch is to verify the size already mounted on the truck and compare it with the wheel diameter stamped on the rim, especially if the truck may have had aftermarket wheels or previous tire changes.
Why does the 2011 Ford Trucks F-350 Super Duty XLT have more than one tire size?
This truck uses more than one tire size because fitment changes with drivetrain, dual-rear-wheel versus single-rear-wheel setup, all-terrain package differences, and wheel options. A 4x2, 4x4, DRW, or 20 Inch Option version does not necessarily share the same wheel diameter or tire dimensions as another XLT configuration.
That variation means a year-make-model match alone is not enough for tire selection on this truck. The safer approach is to identify the exact sub-model and then confirm the wheel size currently on the vehicle, since two trucks with the same trim name can still call for different tire sizes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 Ford Trucks F-350 Super Duty XLT?
Start with the correct primary tire size for the truck's exact sub-model, then compare the available radial tire's rim-width range, maximum load figure at its stated pressure, and overall intended use. On this F-350 Super Duty XLT, that means matching the truck's 17-, 18-, or 20-inch setup before looking at any other specification.
A work-oriented truck may place more emphasis on the tire's load-related specification, while a mixed-use truck may also put more weight on tread character and sidewall presentation. It also helps to confirm whether the truck is stock, because wheel changes or suspension alterations can affect how a correctly sized tire behaves on the vehicle.
What sidewall styles are available for 2011 Ford Trucks F-350 Super Duty XLT tires?
The available sidewall styles for this truck's tire sizes include RWL and RBL, depending on the exact size. Most of the 17-inch and 18-inch BFGoodrich All-Terrain T/A KO2 options use raised white letter sidewalls, while the 275/65R20 option uses an RBL sidewall treatment.
That sidewall difference mainly affects appearance rather than the truck's basic size fitment. Choosing between them usually comes down to whether the owner wants a more traditional all-terrain visual presentation or a more subdued look, while still staying with the correct tire size and wheel diameter for the specific XLT configuration.
What brands offer tires for the 2011 Ford Trucks F-350 Super Duty XLT?
The available products for the listed tire sizes on the 2011 Ford Trucks F-350 Super Duty XLT come from BFGoodrich. The current assortment centers on the All-Terrain T/A KO2 series across the model's 17-inch, 18-inch, and 20-inch radial fitments rather than a mix of multiple brands.
That means the real comparison is less about brand selection and more about choosing the correct size, sidewall treatment, and load-related specification within the BFGoodrich lineup. For this truck, the most useful next step is to match the exact sub-model and wheel diameter first, then compare the product details tied to that size.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Ford Trucks F-350 Super Duty XLT?
A period-style choice for a 2011 Ford Trucks F-350 Super Duty XLT starts with keeping the truck in its correct original-type size and rim diameter for the exact configuration. Since this model uses modern metric radial sizes, the most authentic-looking approach usually comes from preserving the truck's proper 17-, 18-, or 20-inch fitment rather than changing sizes.
Appearance decisions then come down to the available sidewall treatment and whether the tire's overall character suits the truck's intended presentation. If originality matters beyond general period style, it is worth checking build records, window-sticker information, or marque-specific references to confirm how that individual truck was equipped when new.
Does correct tire fitment matter for a 2011 Ford Trucks F-350 Super Duty XLT restoration?
Correct tire fitment matters because the 2011 Ford Trucks F-350 Super Duty XLT was offered with multiple wheel diameters and tire sizes, and the wrong combination can change the truck's stance and overall visual balance. Staying with the proper size for the exact sub-model keeps the restoration grounded in the truck's actual configuration.
Fitment also affects practicality, especially on a heavy-duty pickup where wheel and tire choices are tied to load-oriented use. Even a clean-looking tire can be the wrong choice if its size or wheel range does not match the truck, so restoration-minded owners should verify both appearance and fitment before moving forward.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Ford Trucks F-350 Super Duty XLT?
Yes. Modifications such as aftermarket wheels, offset changes, suspension lifts, leveling kits, lowering, or body alterations can affect tire fitment on a 2011 Ford Trucks F-350 Super Duty XLT even when the tire size itself matches a factory application. This matters because the truck already spans several wheel diameters and tire widths across its original configurations.
A truck that has been changed from stock should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before replacement tires are selected. It is also smart to compare the current tire size on the truck against the intended replacement so the new setup does not create rubbing or load-related compromises.
What should I inspect before driving a 2011 Ford Trucks F-350 Super Duty XLT on new tires?
Before road use, inspect wheel condition, valve stems, lug hardware, and the truck's alignment-related wear patterns so the new tires start on a solid foundation. It also helps to confirm that all four or six tires, depending on the truck's setup, match the intended size and are inflated appropriately for the tire's stated requirements and the truck's use.
A short test drive should include checking for rubbing during turns, unusual vibration, and any sign that the tire is too close to suspension or body components. Heavy-duty trucks also benefit from a quick recheck of pressure and lug torque after initial driving, especially if the wheels were removed during tire installation.
How should tires on a 2011 Ford Trucks F-350 Super Duty XLT be maintained?
Regular tire maintenance on a 2011 Ford Trucks F-350 Super Duty XLT should include pressure checks, visual inspection for cuts or sidewall damage, and close attention to uneven tread wear. Because this is a heavy-duty truck, keeping inflation in line with the tire's intended load use is especially important for stability, wear, and overall service life.
Trucks that sit for long periods still need inspection, since age-related cracking and slow air loss can develop even when mileage stays low. Owners should also monitor tread condition across each tire position and keep an eye on alignment or suspension issues, because those problems often show up in the tires before they become obvious elsewhere.
