The 2006 Ford Trucks F-150 Lariat sits in the era when full-size pickups were expected to do more than work, blending everyday utility with a more upscale trim level and increasingly varied wheel-and-tire packages. That matters when replacing tires, because this exact truck can use three different radial sizes depending on whether it is a 4x2, a 4x4, or equipped with the 20 Inch Option. The key choice is not just brand, but identifying the correct rim diameter and matching the truck's specific configuration. Once that is confirmed, tire selection becomes a practical balance of fitment, appearance, intended use, and overall road-going needs.
Which Tire Size Is Right for The 2006 Ford Trucks F-150 Lariat
The 2006 Ford Trucks F-150 Lariat uses three primary tire sizes, and they are tied to specific configurations rather than being interchangeable across the whole model line. The first step is confirming whether the truck is a 4x2, a 4x4, or fitted with the 20 Inch Option, because the fitment also changes between 18-inch and 20-inch wheels. Once the exact setup is clear, the decision shifts to selecting the right radial tire within that size.
275/55R20 is a metric radial size in which 275 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2006 Ford Trucks F-150 Lariat, this size belongs to the 20 Inch Option and represents a different wheel package from the 18-inch setups used elsewhere in the range. Its dimensions make wheel confirmation especially important before replacement. This size is the right place to start when the truck already has 20-inch wheels and the goal is to preserve that established fitment.
265/60R18 follows the standard metric radial format, with a 265-millimeter nominal section width, a 60-series profile, radial construction, and an 18-inch rim diameter. This size is used on the 2006 Ford Trucks F-150 Lariat 4x2, so it should not be treated as the default choice for every Lariat configuration. The key distinction is that it pairs a narrower section width and different overall dimensions than the other Lariat sizes. It is the correct fitment path when the truck is a 4x2 running the 18-inch wheel setup associated with this size.
275/65R18 is a metric radial size where 275 gives the nominal width in millimeters, 65 identifies the sidewall profile, R stands for radial, and 18 is the wheel diameter in inches. This size is used on the 2006 Ford Trucks F-150 Lariat 4x4 and is also the size with an available BFGoodrich All Terrain TA KO2 option featuring raised white letters. Because product choice here leans toward an all-terrain presentation, buyers should match the tire to how the truck is actually driven. It is the right size to evaluate when the truck is a 4x4 on its 18-inch wheel package.
Tire fitment for the 2006 Ford Trucks F-150 Lariat varies by sub-model and wheel package, so the exact configuration matters before any tire is selected. A 4x2, a 4x4, and the 20 Inch Option do not share the same size, and the wheel diameter changes with them.

2006 Ford Trucks F-150 Lariat (20 Inch Option)
The 20 Inch Option uses 275/55R20 radial tires, making wheel diameter the first thing to confirm on the truck itself. That setup points the search toward maintaining the existing 20-inch package rather than comparing it loosely with the 18-inch Lariat fitments.
The 4x2 version uses 265/60R18 radial tires, which sets it apart from both the 4x4 and the 20 Inch Option. Tire selection starts with staying in that 18-inch size range and checking that the truck still has its matching wheel setup.
The 4x4 uses 275/65R18 radial tires, giving it a distinct fitment within the Lariat lineup. That means replacement choices should be centered on this size and its 18-inch wheel compatibility, especially if the truck is expected to retain a more truck-oriented stance and use pattern.
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.

Owners of a 2006 Ford Trucks F-150 Lariat usually need to sort out exact tire size by sub-model and wheel package first. The questions below focus on fitment, rim diameter, product choice, truck modifications, and road-use checks before mounting new tires.
Tire Size & Fitment
What tire size fits a 2006 Ford Trucks F-150 Lariat?
The 2006 Ford Trucks F-150 Lariat uses three different tire sizes depending on configuration: 275/55R20 for the 20 Inch Option, 265/60R18 for the 4x2, and 275/65R18 for the 4x4. All three are radial sizes, but they are tied to different wheel packages and should be treated as configuration-specific fitments rather than one universal size.
The practical first step is identifying the truck's exact sub-model and checking the wheel diameter already on the vehicle. A tire choice that matches one Lariat setup may not suit another, so verifying the current wheels, reading the existing sidewall, and checking for any past wheel changes will prevent ordering a size that does not match the truck's actual configuration.
What size rim does a 2006 Ford Trucks F-150 Lariat use?
A 2006 Ford Trucks F-150 Lariat uses either an 18-inch or 20-inch rim, depending on sub-model and option package. The 4x2 and 4x4 configurations use 18-inch rims with different tire sizes, while the 20 Inch Option uses a 20-inch rim with 275/55R20 tires.
Rim diameter should be confirmed before anything else because it determines which tire size family the truck can use. An 18-inch tire cannot be mounted on a 20-inch wheel, and the reverse is equally true. Looking at the current tire sidewall or measuring the wheel setup is especially important on trucks that may have had aftermarket wheels installed at some point.
Do all 2006 Ford Trucks F-150 Lariat sub-models use the same tire size?
No. The 2006 Ford Trucks F-150 Lariat does not use one shared tire size across all covered sub-models. The 4x2 uses 265/60R18, the 4x4 uses 275/65R18, and the 20 Inch Option uses 275/55R20, so fitment changes with both drivetrain configuration and wheel package.
That difference matters because the tire decision begins with identifying the truck correctly, not by assuming every Lariat is the same. Once the exact sub-model is confirmed, the next check is whether the truck still carries its matching wheel size. That approach is especially useful on older pickups that may have been upgraded, lifted, lowered, or re-wheeled during their service life.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Ford Trucks F-150 Lariat?
Start with the correct tire size for the truck's exact configuration, since a 2006 Ford Trucks F-150 Lariat may use 275/55R20, 265/60R18, or 275/65R18. After size is confirmed, compare construction, rim-width compatibility where available, load capacity, and the kind of driving the truck actually sees, whether that is mostly pavement use or more mixed-duty use.
The right choice is usually the one that matches the truck's present wheel setup and intended role without drifting away from proper fitment. A street-driven Lariat and a 4x4 used more aggressively may point toward different tire character even within the correct size. Keeping wheel diameter, overall tire proportions, and clearance in mind will help narrow the selection responsibly.
What sidewall styles are available for 2006 Ford Trucks F-150 Lariat tires?
For the currently available 275/65R18 product used on the 2006 Ford Trucks F-150 Lariat 4x4, the sidewall style is RWL, or raised white letter. That gives the truck a more traditional light-truck appearance than a plain black sidewall and can change the overall look even when the tire size itself remains correct.
Sidewall style is mainly an appearance decision, but it should be made after the correct size and wheel fitment are settled. Buyers trying to keep a truck-oriented presentation may prefer raised white letters, while others may want a more understated look when other product choices exist. The key is to treat sidewall styling as a secondary choice, not as a substitute for fitment accuracy.
What brands offer tires for the 2006 Ford Trucks F-150 Lariat?
Current product coverage for this exact fitment includes BFGoodrich in 275/65R18 for the 2006 Ford Trucks F-150 Lariat 4x4. The available example is the All Terrain TA KO2, which combines radial construction with an all-terrain series and raised white letter sidewalls.
Brand choice matters most after the correct sub-model and tire size have been confirmed. Once that foundation is in place, compare the available product's series, sidewall treatment, rim-width range, and load capacity against how the truck is used. That helps keep the decision focused on matching the tire to the F-150's setup instead of choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Ford Trucks F-150 Lariat?
A period-style choice for a 2006 Ford Trucks F-150 Lariat starts with preserving the truck's correct configuration-specific size, whether that is 265/60R18, 275/65R18, or 275/55R20. Keeping the proper wheel diameter and overall fitment approach usually does more for the truck's visual authenticity than chasing a tire that simply looks aggressive or oversized.
Appearance goals should be balanced against how the truck will actually be driven. A truck retained in stock-style trim often benefits from staying close to its established size and wheel package, while modified examples need extra clearance checks. When exact originality matters, vehicle-specific literature and marque-focused references are the right next step before making a purely appearance-driven change.
How does tire construction affect the appearance of a restored 2006 Ford Trucks F-150 Lariat?
On the 2006 Ford Trucks F-150 Lariat, the primary fitments are radial tires, so maintaining the correct radial size keeps the truck in line with its era and intended visual stance. Construction alone does not determine appearance, but profile, sidewall style, and keeping the right wheel diameter all contribute to how the truck sits and presents itself.
A change in size or wheel package usually alters appearance more dramatically than staying within the proper radial fitment. Raised white letters, when available, add a more assertive truck look, while different wheel diameters can shift the character of the entire vehicle. For a restoration-oriented result, it is smart to decide whether the goal is stock-style presentation or a period-inspired personalized look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Ford Trucks F-150 Lariat?
Yes. Modifications can affect tire fitment on a 2006 Ford Trucks F-150 Lariat even when the replacement tire is one of the correct original-size choices for a covered sub-model. Aftermarket wheels, suspension lifts, lowering kits, offset changes, or body alterations can all change the space available around the tire and the way that tire sits on the truck.
That is why it helps to inspect the truck as it currently exists rather than assuming it still matches stock wheel and suspension geometry. Check wheel diameter and width first, then look at inner clearance, fender clearance, and steering travel. A truck that has been modified may need a closer fitment review even when the tire size itself is correct for the original configuration.
What should I inspect before driving a 2006 Ford Trucks F-150 Lariat on new tires?
Before road use, inspect air pressure, wheel hardware, visible clearance at full steering lock, and the general condition of suspension and steering components. It is also smart to confirm that the new tires match the truck's correct size and rim diameter, since the 2006 Ford Trucks F-150 Lariat uses more than one fitment depending on its configuration.
A short local drive followed by a second visual check can catch rubbing, uneven seating, or other early issues before the truck is used normally. Pay attention to vibration, pulling, or any sign of contact inside the wheelwell. Trucks that have sat for long periods also benefit from checking the spare, valve stems, and the condition of any older remaining tires.
What should I check before a longer drive in a 2006 Ford Trucks F-150 Lariat?
Before a longer drive, confirm that the 2006 Ford Trucks F-150 Lariat is on the correct tire size for its sub-model, then inspect pressure, tread condition, sidewalls, and any signs of cuts, bulges, or irregular wear. It is also worth checking for slow air loss and making sure all four road tires are matched appropriately for the truck's intended use.
Longer trips put more sustained heat and load into a tire, so small issues become more important than they might on short local drives. Looking over wheel condition, verifying lug torque, and checking that nothing rubs during turning or suspension movement can prevent roadside problems. A quick inspection of the spare and tire-changing tools is also a sensible part of trip preparation.
