2008 Ford Trucks F-350 Super Duty King Ranch Tires

The 2008 Ford Trucks F-350 Super Duty King Ranch uses four primary radial sizes: 275/65R18, 245/75R17, 275/65R20, and 275/70R18. The correct size depends on the exact truck configuration, including 4x2 or 4x4, single-rear-wheel or dual-rear-wheel, and the wheel package on the truck.

That means the first step is confirming the sub-model and actual wheel diameter before comparing tires. A DRW truck uses a different size from a single-rear-wheel truck, and a 4x4 can use either 18-inch or 20-inch wheels, so checking the current wheel and tire markings helps prevent ordering the wrong fitment.

A 2008 Ford Trucks F-350 Super Duty King Ranch can use 17-inch, 18-inch, or 20-inch rims, depending on the exact tire size and sub-model. The 245/75R17 fitment 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.

Rim diameter should be confirmed before anything else because these sizes are not interchangeable across different wheel diameters. A quick look at the existing tire sidewall or wheel markings usually settles the question, and that check is especially important on used trucks that may have had wheels swapped at some point in their service life.

More than one tire size appears on this truck because the F-350 Super Duty King Ranch was offered in different configurations. Rear-wheel setup and drivetrain affect fitment, so the DRW versions use 245/75R17 while the single-rear-wheel trucks use larger 18-inch or 20-inch radial sizes.

That variation means tire choice is tied to how the truck was built and how it currently sits. A 4x4 truck also needs a wheel-diameter check because it can use either 275/70R18 or 275/65R20, making the wheel itself just as important as the year, make, and model when narrowing down the right tire.

Start with the exact tire size and wheel diameter required by the truck's sub-model. On this F-350 Super Duty King Ranch, that means confirming whether the truck is 4x2 or 4x4, single-rear-wheel or DRW, and then matching the correct radial size before comparing individual tire specifications.

After size is confirmed, compare the tire's rim-width range, load capacity at the stated pressure, sidewall style, and overall product character. A raised white letter look may matter to one owner, while another may want a black sidewall presentation, so the right choice depends on both the truck's setup and how it is used.

Sidewall presentation on these fitments includes RWL and RBL styles. RWL means raised white letters, which appear on the 275/65R18, 245/75R17, and 275/70R18 options, while the 275/65R20 option uses an RBL black sidewall treatment.

That choice affects appearance more than fitment, but it can still shape the overall look of the truck. Raised white letters give the tire a more traditional all-terrain presentation, while a black sidewall looks more understated, so it helps to decide whether visual style matters as much as the tire's size and load-related specifications.

The available series across these fitments is the BFGoodrich All-Terrain T/A KO2. It appears in each of the four primary sizes used on the 2008 Ford Trucks F-350 Super Duty King Ranch, so the main variables are size, rim-width specification, sidewall presentation, load capacity, and product weight.

Since the series remains consistent, choosing among the available tires is really about matching the truck's exact wheel and axle configuration. Once that is settled, the remaining comparison points are practical details such as whether the sidewall appearance suits the truck and whether the tire's specifications align with the intended work or road-use demands.

A period-style choice starts with the correct original-style size for the truck's exact 2008 configuration rather than with appearance alone. On this F-350 Super Duty King Ranch, that means selecting the proper radial fitment for the sub-model first, then narrowing the choice by sidewall style and the overall visual character of the tire.

Raised white letter options can give the truck a more traditional heavy-duty pickup look, while a black sidewall presents a cleaner and more subdued appearance. Owners aiming for a highly exact restoration should compare the truck's surviving equipment, period photos, window-sticker documentation, or marque-specific references before treating any sidewall treatment as historically definitive.

Correct tire fitment matters because the tire size, wheel diameter, and sidewall presentation all contribute to how the truck sits and how authentic the finished package appears. A 2008 F-350 Super Duty King Ranch restored with the wrong wheel diameter or the wrong DRW versus single-rear-wheel fitment can look noticeably out of character.

The practical side matters just as much as the visual side. Matching the correct size to the truck's actual wheel setup helps preserve proper clearance and load-related suitability, and it also prevents a restoration from being undermined by a tire choice that draws attention for the wrong reasons once the truck is back on the road.

Yes, modifications can affect tire fitment on a 2008 Ford Trucks F-350 Super Duty King Ranch. Aftermarket wheels, suspension changes, leveling kits, lift kits, or axle-related changes can alter the wheel diameter, width, and available clearance, which may move the truck away from its original tire-size requirements.

That is why the current setup should always be checked rather than assuming the truck still matches its factory-style configuration. Wheel markings, tire sidewall information, steering clearance, and fender clearance all deserve attention, especially on used heavy-duty pickups where functional upgrades are common and can complicate size selection.

Before road use, inspect the wheel condition, valve stems, lug hardware, tire pressure, and the basic clearance around the tires at full steering lock. It also helps to confirm that all tires match the intended size for the truck's exact configuration, especially on DRW trucks where rear fitment consistency is important.

A short check after installation can prevent bigger problems later. Watch for rubbing, uneven stance, unusual vibration, or signs that the tires are not seated or balanced correctly, and keep an eye on pressure stability during the first few drives so the truck starts its service life on the new tires in sound condition.

Tires on a 2008 Ford Trucks F-350 Super Duty King Ranch should be inspected regularly, not just when a problem appears. Pressure, tread wear, cuts, bulges, sidewall cracking, and uneven wear patterns all deserve routine attention, especially on a heavy-duty truck that may tow, haul, or spend time parked between uses.

Frequent visual checks are a smart habit because they can reveal alignment issues, air loss, or clearance problems before they become serious. Trucks that sit for long periods also benefit from occasional condition checks for age-related deterioration, and any sign of persistent wear or handling change should prompt a closer inspection of the full wheel and suspension setup.
