2019 Ford Trucks F-350 Super Duty Tires

The 2019 Ford Trucks F-350 Super Duty uses five primary tire sizes: 245/75R17, 265/70R17, 275/65R18, 275/70R18, and 275/65R20. All of them are radial sizes, and the correct one depends on the truck's exact trim, drivetrain, wheel package, and whether it is a single rear wheel or dual rear wheel configuration.

The first thing to verify is the truck's actual wheel diameter, because this model range uses 17-inch, 18-inch, and 20-inch rims. After that, confirm the exact sub-model, especially on XL, XLT, King Ranch, Lariat, and snow plow package trucks, since similar-looking F-350s can use different primary tire sizes.

A 2019 Ford Trucks F-350 Super Duty can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model and tire size. The primary size pairings are 245/75R17 and 265/70R17 on 17-inch wheels, 275/65R18 and 275/70R18 on 18-inch wheels, and 275/65R20 on 20-inch wheels.

Rim diameter should be confirmed before looking at tread pattern or sidewall style, because a tire built for one wheel diameter cannot be used on another. On this truck, that matters even more because trim level and DRW status often separate 17-inch work-oriented setups from larger 18-inch and 20-inch single rear wheel fitments.

This F-350 Super Duty line covers a wide range of configurations, so tire size changes with trim level, drivetrain, wheel package, and DRW versus single rear wheel layout. Some trucks use 17-inch fitments, some use 18-inch sizes with different profiles, and others use 20-inch tires tied to specific trim packages.

That means tire selection starts with identifying the exact truck rather than assuming every 2019 F-350 Super Duty uses the same size. A King Ranch 4x4, an XL work truck, and a DRW model can each point to a different fitment path, even though they share the same year, make, and model core.

Start with the exact tire size that matches the truck's sub-model and wheel diameter, since this F-350 Super Duty uses several primary metric radial sizes. From there, compare the available tire's load capacity, rim-width range, and whether the truck is single rear wheel or dual rear wheel before deciding on a specific option.

Intended use matters too. A truck used for heavier work, towing, or mixed pavement and unpaved driving may call for closer attention to load figures and wheel compatibility than a lightly used personal truck. It also helps to confirm the truck has not been changed with aftermarket wheels that alter the original fitment requirements.

The available sidewall treatments for these 2019 Ford Trucks F-350 Super Duty fitments include RWL and RBL, depending on the size. RWL is a raised white letter presentation, while RBL is a raised black letter look. The sidewall style changes with the specific tire size rather than appearing across every fitment.

That makes sidewall choice a secondary decision after the correct size is confirmed. For example, several 17-inch and 18-inch options use raised white letters, while the available 275/65R20 option uses a raised black letter sidewall. Matching the right appearance still begins with choosing the proper size for the truck's configuration.

BFGoodrich is the available brand across the listed 2019 Ford Trucks F-350 Super Duty tire sizes, and the product family offered here is the All-Terrain T/A KO2. That keeps brand choice simple, but there is still variation by size, sidewall treatment, rim-width range, and load-capacity specification within the line.

The practical comparison is less about switching between brands and more about matching the exact KO2 version to the truck's size and intended use. On a model range with 17-inch, 18-inch, 20-inch, SRW, and DRW applications, selecting the right specification matters more than treating all tires in the series as interchangeable.

Yes. Wheel changes, suspension lifts, leveling kits, lowering, or body modifications can all affect tire fitment on a 2019 Ford Trucks F-350 Super Duty. That matters because this truck already uses several factory tire sizes across 17-inch, 18-inch, and 20-inch wheels, so even small setup changes can alter clearance and wheel compatibility.

A modified truck should be checked for actual wheel diameter, wheel width, and available clearance at steering lock and through suspension travel before any replacement tire is chosen. On DRW versions, rear-wheel configuration adds another layer, since a size that works on a single rear wheel truck should not be assumed appropriate here.

Before road use, inspect wheel condition, valve stems, lug hardware, inflation pressure, and the tire sidewalls for any shipping or installation damage. It also helps to confirm that the new tires match the truck's correct size, wheel diameter, and intended axle configuration, especially on trucks that may have changed owners or wheel packages.

A short, careful test drive is worthwhile to check for rubbing, steering interference, vibration, or unusual clearance issues. Heavy-duty trucks should also have load use in mind, so the tire's capacity and the wheel's suitability should remain aligned before the truck goes back into towing, hauling, or winter-duty service.

Tires on a 2019 Ford Trucks F-350 Super Duty should be inspected regularly, not just when tread appears worn. Heavy-duty use places more importance on catching irregular wear, sidewall damage, punctures, cuts, bulges, and pressure loss early, especially on trucks that tow, carry loads, or spend time on rough surfaces.

A monthly check is a sensible routine, with another inspection before longer trips, towing, or seasonal work. On low-use trucks, age and storage conditions still matter, so look for cracking and pressure loss even if mileage is limited. Regular inspection is particularly important when the truck runs all-terrain tires in demanding service.
