The 2006 Ford Trucks F-250 Super Duty Lariat sits in the heavy-duty pickup era when luxury trim and real working capability increasingly came together in one truck. Buyers used these trucks for towing, hauling, daily driving, and off-pavement use, so tire choice matters as much as appearance. This exact F-250 Super Duty Lariat uses radial tire fitments, with four possible sizes depending on the specific configuration and wheel package. That means the first step is confirming whether the truck carries 17-inch, 18-inch, or 20-inch wheels, then narrowing the size by sub-model. From there, the decision shifts to load-focused specs, sidewall style, and matching the tire to how the truck is actually used.
Which Tire Size Is Right for The 2006 Ford Trucks F-250 Super Duty Lariat
The 2006 Ford Trucks F-250 Super Duty Lariat uses four different primary tire sizes, and they do not all fit the same configuration. Fitment changes by sub-model and wheel package, with 17-inch, 18-inch, and 20-inch rim diameters in play. Before choosing a tire, confirm the exact Lariat configuration and the actual wheel diameter on the truck, especially if it has been changed from its original setup.
275/65R18 is a metric radial size in which 275 identifies the section width in millimeters, 65 is the aspect ratio, R marks radial construction, and 18 is the rim diameter in inches. On this F-250 Super Duty Lariat, it applies to the 4x2 18 Inch Option and reflects a modern truck tire format rather than an older bias-ply sizing system. Available choices in this size include BFGoodrich All-Terrain T/A KO2 with an RWL sidewall treatment. It is the right size to evaluate when the truck has the matching 18-inch wheel package and the buyer wants a heavy-duty radial suited to truck use.
265/70R17 is a metric radial size where 265 is the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter. This size appears on the 4x2 Crew Cab, 4x2 Super Cab, and some 4x4 configurations, so it is one of the more broadly used fitments within this Lariat range. BFGoodrich All-Terrain T/A KO2 is available here with raised white letter styling and more than one load-focused specification. It is the size to consider when the truck is running 17-inch wheels and the goal is to stay with the proper primary fitment for that setup.
275/65R20 follows the same metric radial format, using a 275-millimeter section width, a 65-series profile, and a 20-inch rim diameter. Within this F-250 Super Duty Lariat range, it is tied to a 4x4 configuration and immediately points to a different wheel package than the 17-inch and 18-inch options. BFGoodrich All-Terrain T/A KO2 is offered in this size with an RBL sidewall style and a heavy-duty truck-oriented specification. It should only be considered after confirming the truck actually carries 20-inch wheels and has the clearance and wheel specs appropriate to this size.
275/70R18 is a metric radial size that combines a 275-millimeter nominal section width with a taller 70-series profile on an 18-inch rim. On the 2006 F-250 Super Duty Lariat, this size is used on a 4x4 configuration, so it should not be assumed to apply across every Lariat truck wearing 18-inch wheels. BFGoodrich All-Terrain T/A KO2 is available in this size with raised white letter styling and a substantial load-capacity specification. This is the fitment to review when the truck is a 4x4 with the correct 18-inch wheel setup and the buyer wants to preserve the intended primary size.
2006 Ford Trucks F-250 Super Duty Lariat Sub-Model Tires
Sub-model fitment matters on the 2006 Ford Trucks F-250 Super Duty Lariat because tire size changes across 4x2, 4x4, cab configuration, and wheel-option combinations. The quickest way to avoid a mismatch is to identify the exact sub-model first, then confirm the truck’s current wheel diameter before selecting a tire.

2006 Ford Trucks F-250 Super Duty Lariat 4x2 (18 Inch Option)
This 4x2 Lariat uses an 18-inch wheel package with the 275/65R18 radial size, which separates it from the 17-inch 4x2 versions. Tire selection here starts with keeping the 18-inch fitment straight, then comparing the available radial option and its sidewall presentation.
2006 Ford Trucks F-250 Super Duty Lariat 4x2 Crew Cab
The 4x2 Crew Cab uses the 265/70R17 radial size, making it a straightforward fitment once the 17-inch wheel diameter is confirmed. The main decision is choosing the right load-oriented specification within that size and making sure it matches how the truck is driven or worked.
2006 Ford Trucks F-250 Super Duty Lariat 4x2 Super Cab
The 4x2 Super Cab also uses the 265/70R17 radial size, so its fitment path is similar to the Crew Cab version. That keeps the focus on wheel confirmation, load-capacity needs, and selecting the right product variation rather than sorting through multiple primary sizes.
The 4x4 Lariat is the most varied configuration here, using 265/70R17, 275/65R20, or 275/70R18 depending on the wheel setup. Tire selection begins with confirming the exact wheel diameter on the truck, then matching the size to the intended use and overall fitment requirements.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2006 Ford Trucks F-250 Super Duty Lariat Tires for Sale

These answers focus on the exact tire sizes used on the 2006 Ford Trucks F-250 Super Duty Lariat, along with wheel-diameter differences, sub-model fitment, product-selection factors, and the checks worth making before putting a heavy-duty truck back on the road.
Tire Size & Fitment
What tire size fits a 2006 Ford Trucks F-250 Super Duty Lariat?
The 2006 Ford Trucks F-250 Super Duty Lariat uses four possible radial tire sizes: 275/65R18, 265/70R17, 275/65R20, and 275/70R18. The correct size depends on the exact sub-model and wheel package, so there is not one universal fitment across every Lariat configuration.
The most important first step is confirming the truck’s actual wheel diameter and sub-model. A 4x2 Crew Cab or 4x2 Super Cab uses 265/70R17, the 4x2 18 Inch Option uses 275/65R18, and a 4x4 may use 265/70R17, 275/65R20, or 275/70R18. If the truck has aftermarket wheels, verify the current setup before choosing a tire.
What size rim does a 2006 Ford Trucks F-250 Super Duty Lariat use?
A 2006 Ford Trucks F-250 Super Duty Lariat may use 17-inch, 18-inch, or 20-inch rims, depending on the exact configuration. The tire-size range on this truck includes 265/70R17 for 17-inch wheels, 275/65R18 and 275/70R18 for 18-inch wheels, and 275/65R20 for 20-inch wheels.
That makes wheel diameter the key fitment check before comparing tires. The same model name does not guarantee the same wheel package, especially on a heavy-duty truck that may have had wheel changes over time. Reading the size on the current tire and confirming the wheel itself helps prevent choosing a tire that is correct for the model line but wrong for the truck in front of you.
Why does the 2006 Ford Trucks F-250 Super Duty Lariat have more than one tire size?
This F-250 Super Duty Lariat has more than one tire size because fitment changes with sub-model and wheel option. The 4x2 Crew Cab and 4x2 Super Cab use 265/70R17, the 4x2 18 Inch Option uses 275/65R18, and 4x4 versions may use 265/70R17, 275/70R18, or 275/65R20.
That variation is common on trucks with different driveline and wheel-package combinations. It means tire shopping should start with the exact cab and drive configuration, then move to wheel diameter. Looking only at the model name can be misleading, and looking only at wheel appearance can be risky if the truck has been modified since new.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Ford Trucks F-250 Super Duty Lariat?
Start with the correct primary tire size for the exact truck, since this Lariat uses four possible radial fitments. After size, look at wheel diameter, the tire’s load-capacity specification, rim-width compatibility, and whether the truck’s use is more oriented toward highway driving, towing, hauling, or mixed on- and off-road service.
A heavy-duty pickup asks more of a tire than a light collector car, so the match between tire spec and real use matters. The available BFGoodrich All-Terrain T/A KO2 options also vary by sidewall treatment and by load-oriented version in some sizes. Choosing carefully helps keep the truck aligned with both its wheel setup and intended job.
What sidewall styles are available for 2006 Ford Trucks F-250 Super Duty Lariat tires?
The available sidewall styles for this F-250 Super Duty Lariat include RWL and RBL, depending on tire size. Raised white letter styling appears on the 275/65R18, 265/70R17, and 275/70R18 options, while the 275/65R20 option is available with an RBL sidewall treatment.
Sidewall style does not change the basic fitment, but it does affect how the truck presents visually. Some owners want a more traditional truck appearance with raised white letters, while others prefer a more subdued sidewall. The right choice comes after confirming the correct size first, since not every sidewall treatment is available in every fitment.
What tire series are available for the 2006 Ford Trucks F-250 Super Duty Lariat?
The available tire series for these fitments is BFGoodrich All-Terrain T/A KO2. It appears across all four sizes used on the 2006 Ford Trucks F-250 Super Duty Lariat, giving the product range a consistent all-terrain focus rather than splitting the truck across several unrelated series.
That makes the main comparison less about changing series and more about selecting the correct size and the right specification within that size. On 265/70R17, for example, there is more than one KO2 load-oriented version to compare. Rim-width range and sidewall treatment are also worth reviewing as part of the final choice.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Ford Trucks F-250 Super Duty Lariat?
A period-style approach on a 2006 Ford Trucks F-250 Super Duty Lariat starts with using the correct primary radial size for the exact sub-model and wheel package. This truck’s fitments are modern metric radials, so preserving the proper 17-inch, 18-inch, or 20-inch size is more important than chasing a different sizing format.
Appearance then comes from details such as sidewall treatment and maintaining the truck’s intended stance. Raised white letter options suit some Super Duty presentations, while a more restrained sidewall may better fit others. For owners concerned with exact as-delivered appearance, period brochures, build documentation, and marque-specific references are worth consulting.
How does tire construction affect the appearance of a restored 2006 Ford Trucks F-250 Super Duty Lariat?
On this truck, construction is straightforward because the primary fitments are radial. That means the appearance question is less about choosing between bias-ply and radial construction and more about keeping the proper metric truck size, sidewall style, and overall wheel-package look for the specific Lariat configuration.
A tire that is technically close in size but paired with the wrong wheel diameter or a noticeably different visual treatment can change the truck’s presentation. Owners aiming for a clean restoration-oriented look usually benefit from matching the original-style wheel package first, then selecting a sidewall that complements the truck without overstating it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Ford Trucks F-250 Super Duty Lariat?
Yes. Modifications can change tire fitment on a 2006 Ford Trucks F-250 Super Duty Lariat even when the tire size is correct for a stock configuration. Aftermarket wheels, altered wheel width, suspension lifts or lowering, and body or steering changes can all affect whether a given 17-inch, 18-inch, or 20-inch fitment still suits the truck.
That is why current wheel diameter is only the starting point. Wheel width, offset, suspension travel, and clearance at full steering lock are worth checking before mounting a replacement set. A truck used for towing or hauling also deserves a careful review of the tire’s load-oriented specification so the setup matches real-world demands.
What should I inspect before driving a 2006 Ford Trucks F-250 Super Duty Lariat on new tires?
Before road use, inspect wheel condition, valve stems, inflation pressure, lug torque, and basic clearance around the fenders and suspension. It also helps to confirm that the tire size on the truck matches the intended wheel diameter, since this F-250 Super Duty Lariat can use several different fitments depending on configuration.
A short, careful initial drive is a smart follow-up. Pay attention to rubbing at parking-lot steering angles, unusual vibration, and any sign of uneven seating or air loss. Because this is a heavy-duty pickup, it also makes sense to recheck pressure after installation and make sure the selected tire specification suits the truck’s actual work.
How should tires on a 2006 Ford Trucks F-250 Super Duty Lariat be maintained?
Tires on a 2006 Ford Trucks F-250 Super Duty Lariat should be maintained with regular pressure checks, tread inspection, and periodic review for cuts, bulges, cracking, or uneven wear. A truck in this class also benefits from keeping the wheels aligned properly and watching for wear patterns that may point to suspension or steering issues.
Heavy-duty pickups are often used intermittently, loaded unevenly, or driven in mixed conditions, so maintenance should reflect that reality. Checking the tires before longer trips is especially worthwhile. Good storage habits, clean wheels, and attention to slow air loss can help preserve both safety and service life, particularly on trucks that are not driven every day.
