The 2008 Ford Trucks F-350 Super Duty Lariat sits in the heavy-duty pickup world where towing, payload, and four-season utility matter just as much as trim level and appearance. In Lariat form, it blends work-truck capability with a more upscale cabin, so tire choice needs to support both real use and the truck’s exact configuration. This model uses radial tire fitments only, with 245/75R17, 275/65R18, 275/70R18, and 275/65R20 all appearing across different cab, drive, and DRW combinations. Available choices center on BFGoodrich All-Terrain T/A KO2 products, with sidewall presentation varying by size. The key step is matching the tire to the truck’s exact sub-model and wheel diameter before comparing load capacity, rim-width range, and road-use needs.
Which Tire Size Is Right for The 2008 Ford Trucks F-350 Super Duty Lariat
The 2008 Ford Trucks F-350 Super Duty Lariat uses four primary tire sizes, and the right one depends on the truck’s exact sub-model, whether it is single rear wheel or DRW, and which wheel diameter it carries. Because these fitments span 17-inch, 18-inch, and 20-inch rims, the first step is confirming the truck’s cab, drive configuration, and wheel setup before choosing a tire.
275/65R18 is a metric radial size in which 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 serves specific single-rear-wheel configurations rather than the full model range. The available BFGoodrich All-Terrain T/A KO2 version uses a raised white letter sidewall and fits a 7.5- to 9.5-inch rim-width range. This size makes sense when the truck already uses 18-inch wheels and the goal is to stay with the correct primary fitment for that configuration.
Fit(s): 4x2 Crew Cab (DRW), 4x2 Super Cab (DRW), 4x4 Crew Cab (DRW), and 4x4 Super Cab (DRW)
Construction: Radial|Rim: 17 in
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 the 2008 F-350 Super Duty Lariat, this size is tied to the DRW versions, making it an important identifier for dually trucks. The BFGoodrich All-Terrain T/A KO2 offering in this size carries a raised white letter sidewall and is built for a 6.5- to 7.5-inch rim-width range. Choosing this size starts with confirming that the truck is a DRW model and still uses the correct 17-inch wheel setup.
275/65R20 is a metric radial size where 275 gives the nominal width in millimeters, 65 is the aspect ratio, and 20 indicates a 20-inch rim. Within this F-350 Super Duty Lariat range, it appears on a specific 4x4 Crew Cab application, so it should not be assumed across all trims and body styles. The BFGoodrich All-Terrain T/A KO2 option in this size uses an RBL sidewall and fits a 7.5- to 9.5-inch rim-width range. It is the right size to evaluate only after confirming that the truck’s 20-inch wheel package is the one actually on the vehicle.
275/70R18 is a metric radial size with a 275-millimeter nominal section width, a 70-series profile, and an 18-inch rim diameter. On the 2008 F-350 Super Duty Lariat, it applies to certain 4x4 configurations and shares the same basic wheel diameter as 275/65R18 while using a different profile. The BFGoodrich All-Terrain T/A KO2 version carries a raised white letter sidewall and is intended for 7.0- to 9.0-inch rim widths. This size is worth choosing only after verifying the exact 4x4 setup and making sure the truck is not using the alternate 18-inch size.

The 4x2 Super Cab DRW uses 245/75R17 radials rather than the larger single-rear-wheel sizes. That means the buyer should confirm dually status first, then compare the tire’s load-focused specifications and wheel-width suitability for the truck’s existing setup.
2008 Ford Trucks F-350 Super Duty Lariat 4x4 Crew Cab
The 4x4 Crew Cab is the most important sub-model to verify because it appears with two different primary radial sizes: 275/65R20 and 275/70R18. Wheel diameter becomes the first checkpoint, since choosing correctly starts with confirming whether the truck is on 18-inch or 20-inch wheels.

Tire Size & Fitment
What tire size fits a 2008 Ford Trucks F-350 Super Duty Lariat?
The 2008 Ford Trucks F-350 Super Duty Lariat uses four primary radial tire sizes: 275/65R18, 245/75R17, 275/65R20, and 275/70R18. The correct one depends on the exact sub-model, including cab style, 4x2 or 4x4 layout, and whether the truck is single rear wheel or DRW.
That means the first step is identifying the truck’s exact configuration rather than choosing by appearance alone. A DRW model points to 245/75R17, while certain single-rear-wheel versions use one of the larger 18-inch or 20-inch sizes, so the actual wheel diameter should always be confirmed before replacement.
What size rim does a 2008 Ford Trucks F-350 Super Duty Lariat use?
A 2008 Ford Trucks F-350 Super Duty Lariat can use 17-inch, 18-inch, or 20-inch rims, depending on the specific sub-model and tire size. The 245/75R17 fitment uses a 17-inch rim, 275/65R18 and 275/70R18 use 18-inch rims, and 275/65R20 uses a 20-inch rim.
Rim diameter matters because even similar-looking tire sizes are not interchangeable across different wheel diameters. Checking the wheel itself is especially important on used trucks, since aftermarket wheels or prior tire changes can blur the original setup and lead to choosing the wrong size.
Why does the 2008 Ford Trucks F-350 Super Duty Lariat have more than one tire size?
More than one tire size appears on the 2008 Ford Trucks F-350 Super Duty Lariat because the model range includes different cab styles, 4x2 and 4x4 layouts, single-rear-wheel trucks, and DRW trucks. Those configurations use different wheel diameters and tire dimensions to suit their specific setup.
The practical effect is that two trucks wearing the same Lariat badge may not use the same tire at all. Matching the exact sub-model and wheel diameter keeps the search on track and helps avoid buying a tire that matches the trim name but not the truck’s actual configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Ford Trucks F-350 Super Duty Lariat?
Start with the correct primary tire size for the truck’s exact sub-model, then compare construction, rim-width compatibility, load capacity, and the intended use of the truck. On this model, the fitment is radial across the board, but the right size can still vary significantly between DRW and single-rear-wheel versions.
A work-focused truck that tows or carries weight regularly should be checked carefully against the tire’s stated load figure and wheel-width range. Sidewall style may also matter for appearance, but it should come after confirming the size, wheel diameter, and overall suitability for how the truck is actually used.
What sidewall styles are available for 2008 Ford Trucks F-350 Super Duty Lariat tires?
Sidewall presentation varies by size on the 2008 Ford Trucks F-350 Super Duty Lariat. Most of the available sizes use RWL, or raised white letter styling, while the 275/65R20 option uses an RBL sidewall treatment instead.
That difference matters if the truck’s appearance is part of the decision, especially on a Lariat where the wheel-and-tire package can shape the overall look. The right approach is to match the correct size first, then decide whether the available sidewall treatment fits the truck’s intended visual style.
What tire series are available for the 2008 Ford Trucks F-350 Super Duty Lariat?
The available tire series for the 2008 Ford Trucks F-350 Super Duty Lariat is the BFGoodrich All-Terrain T/A KO2 across the supported primary sizes. That keeps the product family consistent even though the vehicle itself uses several different tire sizes depending on configuration.
Consistency in series can simplify selection, but size-specific details still matter. Rim-width range, sidewall style, product weight, and load capacity vary by size, so the buyer should compare those points within the correct fitment rather than assuming every KO2 version is effectively the same.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Ford Trucks F-350 Super Duty Lariat?
A period-style choice for a 2008 Ford Trucks F-350 Super Duty Lariat starts with keeping the truck in its correct primary tire size and wheel diameter for the exact sub-model. Since this is a modern heavy-duty pickup with radial-only fitments, the most authentic-looking approach is usually the proper size paired with an appropriate sidewall presentation.
Raised white letter styling appears on several of the available sizes and can suit the era well, while the 20-inch fitment uses an RBL sidewall. Buyers focused on preserving the truck’s original presentation should also verify the actual wheel package on the vehicle before making an appearance-driven tire choice.
Does correct tire fitment matter for a 2008 Ford Trucks F-350 Super Duty Lariat restoration?
Correct tire fitment matters because this F-350 Super Duty Lariat did not use one universal size across the range. A restoration-minded truck should wear the proper combination of tire size and rim diameter for its specific body, drive, and rear-wheel configuration rather than a size that merely looks close.
That is especially important on DRW trucks and on 4x4 Crew Cab models, where more than one primary fitment appears within the broader model line. A careful restoration should confirm the actual wheels on the truck and use period photos, original paperwork, or marque-specific references if exact presentation matters.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Ford Trucks F-350 Super Duty Lariat?
Yes, modifications can affect tire fitment on a 2008 Ford Trucks F-350 Super Duty Lariat even when the tire size itself is correct for the model line. Aftermarket wheels, changes in wheel width, suspension lifts or lowering, and body or steering alterations can all change the space available around the tire.
That is why an owner should verify the actual wheel diameter and width on the truck instead of relying on trim name alone. Clearance at full steering lock, suspension travel, and rear dual-wheel spacing all deserve attention before mounting replacement tires on a modified heavy-duty pickup.
What should I inspect before driving a 2008 Ford Trucks F-350 Super Duty Lariat on new tires?
Before road use, inspect inflation pressure, wheel condition, valve stems, lug hardware, and the tire’s seating on the rim. It also helps to confirm that all tires on the truck match the intended size and type for that exact configuration, especially on DRW models where consistency matters across the rear setup.
A short low-speed check can reveal rubbing, vibration, or steering interference before the truck is put back into regular service. Looking over suspension wear, alignment condition, and any unusual fender or inner-wheelhouse contact is a smart final step on a vehicle built to carry serious load.
How often should tires on a 2008 Ford Trucks F-350 Super Duty Lariat be inspected?
Tires on a 2008 Ford Trucks F-350 Super Duty Lariat should be inspected regularly, not just when tread appears low. Heavy-duty trucks benefit from frequent checks for air loss, uneven wear, cuts, bulges, sidewall damage, and signs that the tire is not wearing evenly across the tread face.
Inspection is even more important before towing, hauling, or taking a longer highway trip. A truck that sits for stretches should also be checked for age-related cracking and pressure loss, since occasional use can hide tire condition problems that are easy to miss in normal day-to-day driving.
