The 2015 Ford Trucks F-350 Super Duty Lariat sits in the modern heavy-duty pickup world where towing, payload, and everyday road use all matter just as much as appearance. In this trim, tire selection is tied closely to drivetrain and dual-rear-wheel configuration, so the first step is confirming exactly how the truck is equipped. This F-350 Super Duty Lariat uses radial tire fitments that include 275/65R18, 245/75R17, 275/65R20, and 275/70R18. Available choices center more on matching the right metric size, rim diameter, and load-minded construction than on vintage styling details. For any replacement, wheel size, truck configuration, and real-world use should drive the decision.
Which Tire Size Is Right for The 2015 Ford Trucks F-350 Super Duty Lariat
Four primary tire sizes apply to the 2015 Ford Trucks F-350 Super Duty Lariat, and they do not all fit the same truck configuration. Sizes vary by sub-model and wheel diameter, including 17-inch, 18-inch, and 20-inch rims, so the first job is confirming whether the truck is 4x2, 4x4, or dual rear wheel and then checking the actual wheel diameter. Once that is settled, the decision becomes selecting the right radial tire within the correct size and load-focused specification.
275/65R18 is a metric radial size where 275 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On this F-350 Super Duty Lariat, it is one of the standard radial fitments and suits trucks already using an 18-inch wheel setup. The available choice in this size is a BFGoodrich All-Terrain T/A KO2 with raised white letter styling. It is the right size to evaluate when the truck is equipped with this 18-inch fitment and the owner wants to stay with the same overall sizing format.
245/75R17 is a metric radial size with a 245-millimeter nominal section width, a 75-series profile, radial construction, and a 17-inch rim diameter. On this vehicle, it is tied to the dual-rear-wheel versions rather than the single-rear-wheel setups, which makes configuration especially important before replacement. In available products, this size appears as a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewall treatment. It is the size to focus on when maintaining the proper DRW wheel and tire package rather than mixing in single-rear-wheel fitments that belong to other sub-models.
275/65R20 uses the same 275-millimeter nominal width and 65-series profile format as other modern metric radials, but it is built for a 20-inch wheel. For this 2015 F-350 Super Duty Lariat, that larger rim diameter means it applies only to certain 4x4 configurations already running 20-inch wheels. The available tire in this size is a BFGoodrich All-Terrain T/A KO2, and its sidewall treatment differs from the raised-white-letter options seen in some other sizes. This size should be chosen only after confirming the truck's wheel diameter, since moving between 18-inch and 20-inch applications is not just a matter of tire preference.
275/70R18 is a metric radial size with a 275-millimeter nominal width, a taller 70-series profile, and an 18-inch rim diameter. On the 2015 Ford Trucks F-350 Super Duty Lariat, it is used on certain 4x4 configurations, so it should not be assumed to apply across every truck carrying the Lariat name. The available product in this size is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewall styling. It is worth evaluating when the truck already has this 18-inch fitment and the owner wants to preserve the existing size relationship rather than substitute another 18-inch option.
2015 Ford Trucks F-350 Super Duty Lariat Sub-Model Tires
Sub-model fitment matters on the 2015 Ford Trucks F-350 Super Duty Lariat because tire size changes with drivetrain and dual-rear-wheel configuration. Before comparing tires, confirm whether the truck is 4x2, 4x4, or DRW and then match that configuration to the wheel diameter already on the truck.
1
2015 Ford Trucks F-350 Super Duty Lariat 4x2
The 4x2 version uses a single primary radial fitment and follows the 18-inch wheel setup rather than the DRW 17-inch package or the alternate 4x4 choices. Tire selection here is mainly about staying with the correct metric size and confirming wheel compatibility before comparing product details.
2015 Ford Trucks F-350 Super Duty Lariat 4x2 (DRW)
The 4x2 DRW model uses the 245/75R17 radial fitment, which separates it clearly from the single-rear-wheel trucks. Tire replacement should keep the dual-rear-wheel configuration front and center, with close attention to wheel size and matching the truck's existing DRW setup.
The 4x4 configuration has the broadest fitment range, using more than one primary radial size across 18-inch and 20-inch wheel applications. Tire choice starts with verifying the exact wheel diameter and current setup, then selecting the correct metric size rather than assuming every 4x4 Lariat shares one fitment.
2015 Ford Trucks F-350 Super Duty Lariat 4x4 (DRW)
The 4x4 DRW model uses the 245/75R17 radial size, matching the dual-rear-wheel approach rather than the larger single-rear-wheel fitments. Replacement decisions should stay focused on the existing DRW wheel package and avoid crossing over into 18-inch or 20-inch single-rear-wheel sizes.
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.

Available choices for the 2015 Ford Trucks F-350 Super Duty Lariat focus on BFGoodrich All-Terrain T/A KO2 radials in the correct 17-inch, 18-inch, and 20-inch metric sizes. Comparison points include sidewall treatment, rim-width range, and load-capacity specification within each individual size.
Owners of a 2015 Ford Trucks F-350 Super Duty Lariat usually need to sort out tire size by sub-model, wheel diameter, and DRW versus single-rear-wheel setup. These FAQs cover fitment, rim considerations, product selection, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2015 Ford Trucks F-350 Super Duty Lariat?
The 2015 Ford Trucks F-350 Super Duty Lariat uses four primary radial tire sizes: 275/65R18, 245/75R17, 275/65R20, and 275/70R18. The correct size depends on the truck's exact configuration, since 4x2, 4x4, and dual-rear-wheel versions do not all share the same fitment.
The most important first step is identifying whether the truck is single rear wheel or DRW and then confirming the wheel diameter already on it. Two sizes may both look plausible on paper, but a 17-inch, 18-inch, or 20-inch fitment belongs to a specific setup, so replacement should start with the actual sub-model and wheel package.
What size rim does a 2015 Ford Trucks F-350 Super Duty Lariat use?
A 2015 Ford Trucks F-350 Super Duty Lariat may use 17-inch, 18-inch, or 20-inch rims depending on configuration. The 245/75R17 size uses a 17-inch rim, the 275/65R18 and 275/70R18 sizes use 18-inch rims, and the 275/65R20 size uses a 20-inch rim.
Wheel diameter should be confirmed before any tire comparison, because the same truck line carries more than one rim size. Once rim diameter is verified, the next checks are wheel width, truck configuration, and whether the vehicle still has its original wheel package or has been changed to an aftermarket setup.
Why does the 2015 Ford Trucks F-350 Super Duty Lariat have more than one tire size?
More than one tire size appears on the 2015 Ford Trucks F-350 Super Duty Lariat because fitment changes with drivetrain and with dual-rear-wheel versus single-rear-wheel configuration. The 4x4 versions also span more than one wheel diameter, so the Lariat trim name alone is not enough to choose a tire.
That means tire selection should begin with the exact sub-model and the wheels currently on the truck, not just the model badge on the fender. A DRW truck, an 18-inch 4x2 truck, and a 20-inch 4x4 truck can all be correct within this year and model line while needing different sizes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Ford Trucks F-350 Super Duty Lariat?
Start with the exact tire size, rim diameter, and truck configuration. A 2015 Ford Trucks F-350 Super Duty Lariat may use 245/75R17, 275/65R18, 275/70R18, or 275/65R20, so choosing the right tire begins with matching the existing wheel setup and whether the truck is DRW or single rear wheel.
After size is confirmed, compare construction, rim-width compatibility, and load-capacity specification within that size. This truck's available options center on radial all-terrain tires, so the practical choice is less about style variety and more about selecting the correct fitment for how the truck is equipped and used.
What sidewall styles are available for 2015 Ford Trucks F-350 Super Duty Lariat tires?
Sidewall treatments for these F-350 Super Duty Lariat tire sizes include RWL and RBL. Raised white letter styling appears on the 275/65R18, 245/75R17, and 275/70R18 options, while the 275/65R20 option uses an RBL sidewall treatment.
That difference matters mainly for appearance, especially if the truck owner wants a more traditional off-road look or a more understated presentation. Sidewall style should still come after the basic fitment checks, since choosing between white-letter and black-letter treatments does not override the need to match the proper size and rim diameter.
What brands offer tires for the 2015 Ford Trucks F-350 Super Duty Lariat?
The available tires for these 2015 Ford Trucks F-350 Super Duty Lariat fitments are from BFGoodrich. Across the supported sizes, the product line shown is the All-Terrain T/A KO2, offered in the truck's applicable 17-inch, 18-inch, and 20-inch metric radial sizes.
Since brand variety is limited here, the real comparison is between the correct sizes and their corresponding specifications rather than between competing manufacturers. Once the proper fitment is confirmed, it makes sense to compare sidewall treatment, rim-width range, and load figure for that exact size instead of treating all F-350 Lariat tires as interchangeable.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Ford Trucks F-350 Super Duty Lariat restoration?
Correct tire fitment still matters, even on a relatively modern heavy-duty truck like the 2015 Ford Trucks F-350 Super Duty Lariat. Using the proper size for the exact 4x2, 4x4, or DRW configuration helps preserve the truck's intended stance, wheel relationship, and overall appearance.
Appearance details such as sidewall treatment can also influence how finished the truck looks, especially when choosing between raised white letter and black-letter presentations. For an owner pursuing a highly accurate restoration, the safest approach is to confirm the truck's original wheel and tire setup through vehicle-specific documentation before making cosmetic decisions.
How does tire construction affect the appearance of a restored 2015 Ford Trucks F-350 Super Duty Lariat?
On a 2015 Ford Trucks F-350 Super Duty Lariat, construction is straightforward because the primary fitments are radial tires. That means the appearance difference comes less from bias-ply versus radial construction and more from the correct metric size, wheel diameter, and sidewall treatment used on the finished truck.
A truck wearing the right 17-inch, 18-inch, or 20-inch fitment will generally look more settled and appropriate than one carrying a mismatched substitute. Raised white letters can create a stronger all-terrain visual statement, while a black-letter sidewall gives a more restrained look without changing the need for proper fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Ford Trucks F-350 Super Duty Lariat?
Yes, modifications can affect tire fitment on a 2015 Ford Trucks F-350 Super Duty Lariat. Aftermarket wheels, suspension changes, altered ride height, or body changes can all influence which of the truck's original tire sizes still make sense and whether steering or fender clearance remains acceptable.
Even when a tire matches one of the known factory size formats, wheel width and actual wheel diameter still need to be checked on a modified truck. A sensible approach is to verify the current setup first, then compare the selected tire against that hardware instead of assuming the truck still matches stock configuration.
What should I inspect before driving a 2015 Ford Trucks F-350 Super Duty Lariat on new tires?
Before putting a 2015 Ford Trucks F-350 Super Duty Lariat into regular road use on new tires, inspect wheel condition, valve stems, inflation pressure, and visible clearance at full steering lock. It also makes sense to confirm that all tires match the correct size for the truck's sub-model and wheel package.
A heavy-duty truck benefits from a careful walk-around after installation, looking for uneven spacing, rubbing, air loss, or anything unusual under load. Tire age on the removed set can also tell part of the story, since worn suspension parts or alignment issues may reveal themselves through irregular tread wear.
How should tires on a 2015 Ford Trucks F-350 Super Duty Lariat be maintained?
Tires on a 2015 Ford Trucks F-350 Super Duty Lariat should be maintained with regular pressure checks, periodic inspection for cuts or bulges, and close attention to tread condition across all positions. Because this is a heavy-duty pickup, even a correct size needs to be kept in proper condition for the truck's real workload.
Maintenance also means watching for uneven wear that could point to alignment, suspension, or loading issues rather than a problem with the tire alone. Trucks that sit for stretches should still be inspected for age-related sidewall condition and air loss before a long drive, especially if they alternate between work use and storage.
