2008 Ford Trucks F-350 Super Duty XLT Tires

The 2008 Ford Trucks F-350 Super Duty XLT uses three primary radial tire sizes: 275/65R18, 245/75R17, and 275/70R18. The correct one depends on the truck’s exact configuration, with 4x2 single-rear-wheel trucks using 275/65R18, 4x4 single-rear-wheel trucks using 275/70R18, and dual-rear-wheel models using 245/75R17.

The practical takeaway is that size selection starts with identifying more than just the model name. Cab style matters, but the big dividing lines are 4x2 versus 4x4 and SRW versus DRW, since those also change wheel diameter. Confirm the truck’s current wheel setup before choosing a tire, especially if it has been modified or re-wheeled.

A 2008 Ford Trucks F-350 Super Duty XLT uses either a 17-inch or 18-inch rim, depending on the sub-model. The 245/75R17 fitment uses a 17-inch wheel, while both 275/65R18 and 275/70R18 use 18-inch wheels.

That means wheel diameter has to be confirmed before comparing tires, even when two trucks share the same year, make, and model designation. A dual-rear-wheel truck and a single-rear-wheel truck do not use the same wheel size here, and 4x2 versus 4x4 also affects which 18-inch tire size belongs on the truck.

More than one tire size appears on the 2008 Ford Trucks F-350 Super Duty XLT because the truck was offered in multiple working configurations. Drivetrain and rear-wheel setup change the fitment, which is why 4x2 SRW, 4x4 SRW, and DRW models do not all share one tire size.

That variation is normal on a heavy-duty pickup, but it makes assumptions risky. Matching by year and model alone is not enough when the same truck family spans different wheel diameters and tire profiles. Checking the exact sub-model and the wheels actually on the truck will prevent choosing the wrong size.

Start with the exact primary tire size for the truck’s configuration, then compare construction, load capacity, rim-width range, and intended use. All three fitments for the 2008 Ford Trucks F-350 Super Duty XLT are radial, but they do not serve the same wheel packages or truck layouts.

A heavy-duty pickup places more importance on matching the tire to the actual wheel and working setup than on appearance alone. Look at the tire’s load figure at its stated pressure, make sure the rim-width specification suits the wheel on the truck, and confirm that SRW or DRW fitment has not been mixed up.

The available products for the 2008 Ford Trucks F-350 Super Duty XLT use an RWL sidewall, meaning raised white letters. That styling appears across the offered BFGoodrich All-Terrain T/A KO2 fitments in 275/65R18, 245/75R17, and 275/70R18.

Sidewall style matters mostly as an appearance choice once the correct size and load-oriented fitment are established. Raised white letters give the truck a more traditional off-road and heavy-duty look, but the more important checks remain the exact tire size, proper wheel diameter, and whether the truck is SRW or DRW.

BFGoodrich is the brand represented across the current size-specific tire choices for the 2008 Ford Trucks F-350 Super Duty XLT. The available fitments are in the All-Terrain T/A KO2 series, covering each of the three primary radial sizes used on this truck.

With a single brand and series in view, comparison becomes more about matching the correct size and checking the specifications tied to that size. Load capacity, wheel-width range, and tire weight differ from one fitment to another, so the right choice still depends on the truck’s exact configuration rather than on brand alone.

Yes, modifications can affect tire fitment on a 2008 Ford Trucks F-350 Super Duty XLT. Aftermarket wheels, suspension lifts, leveling kits, altered offsets, or SRW-to-DRW-related wheel changes can all change how a tire sits in the wheel opening and whether the wheel itself matches the tire’s required diameter and width range.

Even when a tire matches one of the correct factory size patterns, the truck’s current setup still needs to be checked. Verify wheel diameter, wheel width, and clearance at the fenders, suspension, and steering components. On a working truck, it is also smart to confirm that the tire’s load specification still suits the way the truck is used.

Before driving a 2008 Ford Trucks F-350 Super Duty XLT on new tires, inspect the wheel condition, valve stems, lug hardware, and inflation pressure, then confirm that the installed tire size matches the truck’s exact configuration. It is also worth checking for any rubbing at full steering lock and through normal suspension movement.

A heavy-duty truck benefits from a short shakedown inspection after installation as well. Recheck pressure, look for uneven seating or contact marks, and pay attention to any vibration that suggests a wheel or balance issue. On DRW trucks especially, keeping the correct size and proper setup matched side to side is important before regular road use.

Tires on a 2008 Ford Trucks F-350 Super Duty XLT should be inspected regularly, with pressure and visible condition checked before longer trips and at routine intervals during normal use. Look for uneven wear, cuts, punctures, bulges, cracking, and slow air loss, especially on a truck that tows, hauls, or sits for stretches between drives.

Regular inspection matters because a heavy-duty pickup can place higher demands on its tires than a lighter vehicle. Keeping an eye on tread condition and inflation helps protect ride quality, load handling, and even tire wear across the axle. Any sign of damage or unexplained pressure loss deserves attention before the truck goes back on the road.
