2026 Ford Trucks F-350 Super Duty Tires

The 2026 Ford Trucks F-350 Super Duty uses six different radial tire sizes: 275/65R20, 245/75R17, 285/75R18, 275/65R18, 275/70R18, and 285/70R17. The correct size depends on the exact trim, whether the truck is single- or dual-rear-wheel, and whether it carries packages such as Tremor Off-Road or Black Appearance.

The most important step is verifying the truck's exact sub-model and actual wheel diameter before choosing a tire. Some versions share a trim name but still use different sizes, and several F-350 configurations move between 17-, 18-, and 20-inch wheels. Matching the tire to the wheel already on the truck is the best starting point.

A 2026 Ford Trucks F-350 Super Duty may use a 17-inch, 18-inch, or 20-inch rim depending on configuration. The tire lineup confirms all three diameters across the model range, with 245/75R17 and 285/70R17 on 17-inch wheels, several 18-inch fitments, and 275/65R20 on 20-inch wheels.

Wheel diameter needs to be confirmed before comparing any tire option, because the same model line does not share one universal rim size. Looking at the tire sidewall or measuring the wheel already on the truck is a smart check, especially on used trucks or those that may have had wheel packages changed after delivery.

The 2026 Ford Trucks F-350 Super Duty spans many trim and equipment combinations, so tire fitment changes with wheel package, driveline, dual-rear-wheel layout, and off-road package. That is why the model line uses six different radial sizes rather than one standard fitment across every truck wearing the F-350 Super Duty badge.

This matters because two trucks that both say Lariat, XL, or XLT may still need different tires. Some use 17-inch wheels, others use 18-inch or 20-inch wheels, and certain packages add their own fitment. Tire selection gets much easier once the exact sub-model and current wheel setup are confirmed first.

Start with the exact tire size and wheel diameter used on the truck, since the 2026 Ford Trucks F-350 Super Duty can take six different radial sizes. After that, compare the tire's intended use, rim-width range, load-at-pressure specification, sidewall style, and whether the truck is a work, dual-rear-wheel, or off-road-oriented configuration.

The right choice depends on how the truck is used and how it is equipped. A Tremor truck, a DRW truck, and a standard single-rear-wheel trim do not ask the same things from a tire. Matching the tire to the wheel first, then comparing construction details and product specs, keeps the decision grounded and practical.

Available sidewall styles for the 2026 Ford Trucks F-350 Super Duty include RWL and RBL, depending on the exact tire size. The BFGoodrich All-Terrain T/A KO2 offerings in 245/75R17, 275/65R18, 275/70R18, and 285/70R17 use RWL, while the 275/65R20 option uses an RBL sidewall.

Sidewall style mainly affects appearance, but it can also help narrow the right product once the correct size is confirmed. Since the sidewall treatment varies by fitment, it should not be chosen ahead of size and wheel diameter. Settle the truck's exact tire size first, then compare the sidewall look that comes with that fitment.

BFGoodrich is the available brand across the listed 2026 Ford Trucks F-350 Super Duty tire products, with the All-Terrain T/A KO2 series covering several of the model's fitments. That includes product availability in sizes such as 275/65R20, 245/75R17, 275/65R18, 275/70R18, and 285/70R17.

Since the visible product range is concentrated in one brand and one all-terrain series, the buying decision becomes more about exact size, sidewall treatment, rim-width specification, and load-at-pressure details than about cross-brand comparison. That can simplify shopping, provided the truck's specific trim and wheel package have already been confirmed.

Yes. Wheel swaps, suspension changes, lift kits, leveling kits, and package-related alterations can all affect tire fitment on a 2026 Ford Trucks F-350 Super Duty. That matters even more on this model because it already spans 17-, 18-, and 20-inch wheel diameters and uses multiple tire sizes across the factory configuration range.

A truck that has aftermarket wheels or altered ride height should be checked for wheel width, actual rim diameter, steering clearance, and fender clearance before any replacement tire is chosen. The size on the truck today may not match the original configuration, so using the current wheel-and-clearance setup as the reference point is the safer approach.

Before driving a 2026 Ford Trucks F-350 Super Duty on new tires, inspect the wheels for correct diameter and condition, confirm that the installed tires match the truck's required size, and check inflation pressure carefully. It is also wise to look over valve stems, lug hardware, and any visible suspension or steering components.

A heavy-duty truck puts real demand on its tires, so a quick visual check should continue after installation. Watch for uneven clearance, rubbing at full steering lock, vibration, or unusual wear during the first miles. On a used truck, especially one with package changes or aftermarket parts, those early checks can prevent fitment surprises.

Tires on a 2026 Ford Trucks F-350 Super Duty should be inspected regularly, not just when tread looks low. Frequent pressure checks, routine visual inspection for cuts, cracking, bulges, and irregular wear, and close attention before towing, hauling, or longer highway trips are all sensible habits for a heavy-duty pickup.

This truck's different fitments and load-capable tire options make condition monitoring especially important. A tire can still have tread yet be a poor road-use candidate if it is losing air or showing sidewall damage. Consistent inspection helps catch issues early and gives the owner a better chance to correct alignment, inflation, or clearance problems before they worsen.
