The 2006 Ford Trucks F-350 Super Duty Lariat sits in the heavy-duty pickup era when towing, payload, and four-door comfort were expected to live in the same truck. In Lariat trim, the F-350 combines work-truck capability with a more upscale presentation, so tire choice needs to respect both load demands and the truck’s actual cab, drive, and wheel setup. This model uses four primary radial sizes: 275/65R18, 245/75R17, 275/65R20, and 275/70R18. That makes the key decision less about vintage-style construction and more about confirming the correct sub-model and rim diameter first. Once that is settled, the focus shifts to load-carrying specs, sidewall treatment, and real-world clearance.
Which Tire Size Is Right for The 2006 Ford Trucks F-350 Super Duty Lariat
The 2006 Ford Trucks F-350 Super Duty Lariat uses four primary tire sizes, and they do not all share the same wheel diameter. Fitment changes by sub-model, including 4x2 versus 4x4 and dual rear wheel configurations, so the first step is identifying the exact truck and confirming whether it has 17-inch, 18-inch, or 20-inch wheels. Once that is clear, the tire decision becomes a matter of matching the correct radial size to the truck’s intended use and wheel setup.
275/65R18 is a metric radial size in which 275 is the nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On the 2006 Ford Trucks F-350 Super Duty Lariat, this size suits certain single-rear-wheel configurations and keeps the truck in a modern heavy-duty radial format. Available choices in this size include BFGoodrich’s All-Terrain T/A KO2 with a raised white letter sidewall. It is the right size to evaluate when your Lariat uses 18-inch wheels and you want a tire that balances truck-duty capability with an all-terrain presentation.
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 this F-350 Super Duty Lariat, it is tied to dual rear wheel sub-models, making it an important fitment distinction rather than a general alternative for every truck on the page. BFGoodrich offers this size in the All-Terrain T/A KO2 with raised white letters. This is the size to confirm when the truck is a DRW configuration and wheel diameter needs to line up with the narrower 17-inch setup.
275/65R20 is a metric radial size that uses a 275-millimeter nominal width, a 65-series aspect ratio, radial construction, and a 20-inch wheel. For the 2006 Ford Trucks F-350 Super Duty Lariat, this size appears on a 4x4 Crew Cab configuration, so it should be treated as a specific fitment rather than a universal option across the model line. In available products, BFGoodrich offers the All-Terrain T/A KO2 in this size with an RBL sidewall treatment. It is the size to examine when the truck already has 20-inch wheels and the owner wants to preserve that wheel-and-tire relationship.
275/70R18 is a metric radial size where 275 identifies nominal section width in millimeters, 70 is the aspect ratio, R marks radial construction, and 18 is the wheel diameter in inches. On the 2006 Ford Trucks F-350 Super Duty Lariat, this size is used on certain 4x4 sub-models and should be matched carefully to the truck’s exact cab and axle arrangement. BFGoodrich offers this fitment in the All-Terrain T/A KO2 with raised white letters. It is the size to review when the truck is on 18-inch wheels but requires the 70-series profile rather than the 65-series 18-inch alternative.

Tire questions for the 2006 Ford Trucks F-350 Super Duty Lariat usually come down to exact sub-model fitment, wheel diameter, DRW versus single-rear-wheel setup, and choosing the right radial tire for towing, hauling, and road use.
Tire Size & Fitment
What tire size fits a 2006 Ford Trucks F-350 Super Duty Lariat?
The 2006 Ford Trucks F-350 Super Duty Lariat uses four primary radial tire sizes: 275/65R18, 245/75R17, 275/65R20, and 275/70R18. The correct size depends on the exact sub-model, including whether the truck is 4x2 or 4x4, Crew Cab or Super Cab, and single rear wheel or DRW.
That means the safest starting point is not choosing by appearance alone, but matching the tire to the truck’s actual wheel diameter and configuration. A DRW truck uses a different fitment path than a single-rear-wheel truck, and a 4x4 Crew Cab may use either an 18-inch or 20-inch setup, so the existing wheels should be verified before selecting tires.
What size rim does a 2006 Ford Trucks F-350 Super Duty Lariat use?
A 2006 Ford Trucks F-350 Super Duty Lariat may use 17-inch, 18-inch, or 20-inch rims, depending on the exact sub-model and tire size. The 245/75R17 fitment uses a 17-inch rim, both 275/65R18 and 275/70R18 use 18-inch rims, and 275/65R20 uses a 20-inch rim.
Rim diameter is the first fitment detail to confirm because tire sizes are not interchangeable across different wheel diameters. Once the wheel diameter is settled, it also helps to check wheel width against the tire’s supported range, especially on a heavy-duty truck where towing, payload, and steering clearance can all be affected by an incorrect wheel-and-tire combination.
Why does the 2006 Ford Trucks F-350 Super Duty Lariat have more than one tire size?
The 2006 Ford Trucks F-350 Super Duty Lariat has more than one tire size because fitment changes with cab style, drive layout, and whether the truck is single rear wheel or dual rear wheel. That is why this model line includes 245/75R17, 275/65R18, 275/70R18, and 275/65R20 radial sizes.
This kind of variation is common on heavy-duty pickups because different configurations place different demands on wheels and tires. Instead of treating all Lariat trucks the same, identify the exact sub-model and inspect the current wheel setup. That avoids ordering a tire for the wrong rim diameter or selecting a single-rear-wheel size for a DRW truck.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Ford Trucks F-350 Super Duty Lariat?
Start with the correct tire size for the exact truck, since the 2006 Ford Trucks F-350 Super Duty Lariat uses several different radial fitments. From there, compare the tire’s load capacity, supported rim-width range, overall size category, and whether the truck is a single-rear-wheel or DRW configuration.
A heavy-duty pickup asks more from its tires than a light commuter vehicle, so the right choice depends on how the truck is actually used. Towing, hauling, off-pavement driving, and everyday street use can all influence which correct-size option makes the most sense, especially when wheel diameter and clearance need to remain consistent.
What sidewall styles are available for 2006 Ford Trucks F-350 Super Duty Lariat tires?
Sidewall styles for the 2006 Ford Trucks F-350 Super Duty Lariat include RWL and RBL, depending on tire size. The 275/65R18, 245/75R17, and 275/70R18 BFGoodrich All-Terrain T/A KO2 options use RWL, while the 275/65R20 version uses an RBL sidewall treatment.
That difference matters mostly for appearance, since the sidewall style changes the truck’s visual presentation without changing the need for the correct fitment. Buyers who care about how the truck looks on the road should compare sidewall treatment after confirming the proper tire size, rim diameter, and wheel setup for their exact Lariat configuration.
What tire series are available for the 2006 Ford Trucks F-350 Super Duty Lariat?
The available tire series for the 2006 Ford Trucks F-350 Super Duty Lariat is BFGoodrich All-Terrain T/A KO2 across the covered sizes. That means the main selection difference is not between several series, but between the correct size, wheel diameter, sidewall treatment, and load-related specifications tied to each fitment.
Even within one tire series, the details still matter on an F-350. A 17-inch DRW tire and a 20-inch single-rear-wheel tire serve very different setups, and their load capacities, weights, and wheel-width ranges are not the same. The product grid is most useful when comparing those size-specific details after the truck’s exact configuration has been confirmed.
Restoration & Appearance
Does correct tire fitment matter for a 2006 Ford Trucks F-350 Super Duty Lariat restoration?
Yes, correct tire fitment matters on a 2006 Ford Trucks F-350 Super Duty Lariat even though it is newer than a traditional collector-era truck. The right size preserves the intended wheel diameter and overall stance of the exact cab, drive, and DRW or single-rear-wheel configuration being restored or refreshed.
Appearance can change noticeably when the wrong diameter or profile is used, especially on a heavy-duty pickup with large wheel openings. A restoration-minded buyer should begin with the truck’s proper size, then compare sidewall treatment and tire presentation. When exact historical appearance is important, period sales materials or marque-specific references can help narrow cosmetic choices.
Which sidewall style suits a period-style 2006 Ford Trucks F-350 Super Duty Lariat?
A period-style 2006 Ford Trucks F-350 Super Duty Lariat can reasonably be matched with either RWL or RBL depending on the wheel-and-tire combination already on the truck. In the available fitments, RWL appears on the 17-inch and most 18-inch options, while the 20-inch 275/65R20 uses an RBL sidewall.
The better choice depends on the look you want to preserve. Raised white letters create a more assertive truck and all-terrain presentation, while RBL gives a more subdued sidewall appearance. Either way, sidewall style should come after confirming the exact size, because keeping the proper 17-inch, 18-inch, or 20-inch fitment matters more than the lettering treatment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Ford Trucks F-350 Super Duty Lariat?
Yes, modifications can affect tire fitment on a 2006 Ford Trucks F-350 Super Duty Lariat. Aftermarket wheels, suspension lifts or lowering changes, steering components, and body alterations can all change the clearance relationship between the tire and the truck, even when the tire size matches one of the original fitment paths.
A truck with changes from stock should be checked carefully for wheel diameter, wheel width, and clearance at full steering lock and suspension movement. That is especially important on a DRW truck or a 4x4 using larger wheel packages, where the wrong wheel-and-tire combination can create rubbing or reduce the margin needed for heavy-duty use.
What should I inspect before driving a 2006 Ford Trucks F-350 Super Duty Lariat on new tires?
Before driving a 2006 Ford Trucks F-350 Super Duty Lariat on new tires, inspect wheel condition, verify lug hardware, confirm the tire size matches the truck’s exact configuration, and set inflation correctly for the tire and vehicle application. It also helps to look over suspension and steering components for wear that could affect tracking or tire wear.
A short initial road test is a smart follow-up. Pay attention to vibration, pull, rubbing, and any unusual contact around the fenders or inner wheel areas, particularly if the truck has non-stock wheels. On an F-350, those checks matter because towing, hauling, and rougher-duty service can quickly reveal a setup problem that lighter use might not expose.
How should tires on a 2006 Ford Trucks F-350 Super Duty Lariat be maintained?
Tires on a 2006 Ford Trucks F-350 Super Duty Lariat should be maintained with regular pressure checks, tread and sidewall inspections, and routine attention to irregular wear. Heavy-duty trucks benefit from catching air loss, cracking, cuts, and shoulder wear early, since those issues can grow faster under towing, payload, or rough-surface use.
Storage and usage patterns matter too. A truck that sits for long periods should still have its tires inspected for age-related condition, and a working truck should have wheel alignment and suspension condition reviewed if wear becomes uneven. Keeping the correct pressure and watching for changes in ride or steering feel can help extend tire life and maintain predictable road behavior.
