The 2008 Ford Trucks F-150 Lariat sits in the late run of the eleventh-generation F-150, a period when this pickup blended work-truck capability with more upscale trim and everyday comfort. Buyers often use these trucks as a mix of highway cruiser, tow vehicle, and weekend hauler, which makes exact tire sizing especially important. Tire fitment on the 2008 Ford Trucks F-150 Lariat is not one-size-fits-all, with radial sizes tied to specific 18-inch and 20-inch wheel setups. That means the key decision is confirming the truck’s exact sub-model or wheel option first, then choosing the right tire within that size for appearance, use, and load needs.
Which Tire Size Is Right for The 2008 Ford Trucks F-150 Lariat
Three tire sizes apply to the 2008 Ford Trucks F-150 Lariat, and they vary by sub-model and wheel package. The first step is identifying whether the truck is a 4x2, a 4x4, or equipped with the 20 Inch Option, because fitment also changes between 18-inch and 20-inch rims. Once that is confirmed, the decision shifts to selecting the right radial tire for the truck’s intended use and wheel specifications.
275/55R20 is a metric radial size in which 275 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2008 Ford Trucks F-150 Lariat, this size belongs to the 20-inch wheel setup rather than every Lariat configuration. Its shorter sidewall relative to the 18-inch sizes gives this fitment a distinctly wheel-package-specific character. The right choice here starts with confirming that the truck actually has the factory-style 20-inch wheel arrangement and enough clearance for this exact size.
265/60R18 is a metric radial size that combines a 265-millimeter section width with a 60-series profile on an 18-inch rim. This size is used on the 2008 Ford Trucks F-150 Lariat 4x2, making it a sub-model-specific fitment rather than a universal Lariat tire. Compared with the other sizes used across the lineup, it represents one of the truck’s 18-inch wheel configurations and should be selected with that exact setup in mind. Confirming both drivetrain and actual wheel diameter is the practical first step before comparing available replacement tires.
275/65R18 is a metric radial size with a 275-millimeter section width, a 65-series profile, and an 18-inch rim diameter. On the 2008 Ford Trucks F-150 Lariat, this size is associated with the 4x4 configuration, so it should be treated as a specific fitment rather than an across-the-board Lariat size. Available product choice in this size includes BFGoodrich, with an All Terrain TA KO2 option and raised white letter sidewall styling. This size makes the most sense when the truck retains the correct 18-inch wheel setup and the owner wants a tire that matches the 4x4 fitment profile.
Tire fitment on the 2008 Ford Trucks F-150 Lariat varies by sub-model and wheel package, so checking the exact configuration matters before choosing a replacement. The main split is between 18-inch and 20-inch setups, with different radial sizes tied to the 4x2, 4x4, and 20 Inch Option versions.

2008 Ford Trucks F-150 Lariat (20 Inch Option)
The 2008 Ford Trucks F-150 Lariat (20 Inch Option) uses the 20-inch wheel fitment, which sets it apart from the Lariat models on 18-inch rims. Tire selection here starts with confirming that wheel package, then choosing a radial tire that matches the truck’s size and clearance needs.
The 2008 Ford Trucks F-150 Lariat 4x2 uses one of the 18-inch radial tire fitments rather than the 20-inch option or the 4x4 size. That makes accurate sub-model identification important before comparing replacement tires, especially if the truck has seen wheel changes over the years.
The 2008 Ford Trucks F-150 Lariat 4x4 uses the larger 18-inch fitment tied specifically to the four-wheel-drive version. That means tire selection should focus on the correct 4x4 size first, then on factors such as tread style, sidewall presentation, rim-width compatibility, and intended road use.
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.

Tire Size & Fitment
What tire size fits a 2008 Ford Trucks F-150 Lariat?
The 2008 Ford Trucks F-150 Lariat uses three possible tire sizes: 275/55R20, 265/60R18, and 275/65R18. The 275/55R20 size belongs to the 20 Inch Option, 265/60R18 is used on the 4x2, and 275/65R18 is used on the 4x4.
That means the right tire size depends on the truck’s exact configuration rather than the Lariat badge alone. Checking the drivetrain and the actual wheel diameter is the safest first step, especially on a used truck that may have had wheels or tires changed since new.
What size rim does a 2008 Ford Trucks F-150 Lariat use?
A 2008 Ford Trucks F-150 Lariat uses either an 18-inch or 20-inch rim, depending on the specific sub-model or wheel option. The 4x2 and 4x4 fitments use 18-inch rims, while the 20 Inch Option uses a 20-inch rim.
Rim diameter needs to match the tire size exactly, so it should be confirmed before looking at replacement tires. It also helps to verify the wheel width and whether the truck still has its original wheels, since aftermarket replacements can change the fitment picture.
Why does the 2008 Ford Trucks F-150 Lariat have more than one tire size?
The 2008 Ford Trucks F-150 Lariat has more than one tire size because tire fitment changes with sub-model and wheel package. The 4x2, 4x4, and 20 Inch Option versions do not all use the same wheel diameter or the same overall tire specification.
That variation is normal on trucks that were offered with different driveline and wheel combinations. Before choosing a replacement, it helps to confirm the exact trim configuration on the truck, then compare the sidewall size marking on the current tires to the wheel actually installed.
Choosing the Right Tire
What should I consider when choosing a 275/65R18 tire for a 2008 Ford Trucks F-150 Lariat?
Start with the basic fitment match: 275/65R18 is the tire size used on the 2008 Ford Trucks F-150 Lariat 4x4. From there, compare construction, sidewall style, load capacity, weight, and rim-width compatibility so the tire suits how the truck is actually used.
A 275/65R18 option in this application includes the BFGoodrich All Terrain TA KO2 with raised white letters, a 3,415-pound load capacity at 80 psi, a 7.5- to 9.5-inch rim-width range, and a listed weight of 57 pounds. Those details matter most when the truck sees mixed road and utility use.
What sidewall styles are available for 2008 Ford Trucks F-150 Lariat tires?
For the 275/65R18 fitment used on the 2008 Ford Trucks F-150 Lariat 4x4, an available sidewall style is RWL, or raised white letter. That gives the truck a more traditional light-truck look than a plain black sidewall presentation.
Sidewall style is mainly an appearance decision unless a specific tire line also brings different tread or load characteristics with it. Once the correct size is confirmed, the sidewall treatment can help shape whether the truck looks more factory-inspired, more off-road oriented, or simply more period-appropriate.
What brands offer tires for the 2008 Ford Trucks F-150 Lariat?
An available tire brand for the 2008 Ford Trucks F-150 Lariat in the 275/65R18 4x4 size is BFGoodrich. That product is offered in the All Terrain TA KO2 series and uses radial construction with a raised white letter sidewall treatment.
Brand matters most after the correct size and wheel setup are nailed down. The useful comparison points are the tire series, sidewall look, load specification, and rim-width fit rather than the brand name alone, especially if the truck is used for a mix of everyday driving and truck duty.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Ford Trucks F-150 Lariat?
A period-style choice for a 2008 Ford Trucks F-150 Lariat starts with the correct size for the truck’s actual configuration: 265/60R18 for the 4x2, 275/65R18 for the 4x4, or 275/55R20 for the 20 Inch Option. Keeping the correct wheel diameter and tire proportions matters more than chasing a generic truck tire look.
Appearance can then be refined through tire series and sidewall treatment. On the 275/65R18 4x4 fitment, a raised white letter BFGoodrich All Terrain TA KO2 gives a more traditional truck presentation, but exact originality should still be checked against vehicle-specific references if a restoration has strict historical goals.
How does tire construction affect the appearance of a restored 2008 Ford Trucks F-150 Lariat?
Tire construction is straightforward on the 2008 Ford Trucks F-150 Lariat because the primary fitments are radial sizes across all listed configurations. That means the visual differences come less from bias-ply versus radial choice and more from the tire’s profile, tread style, and sidewall presentation within the correct radial size.
For a restoration-minded truck, matching the proper size to the proper wheel diameter keeps the stance and overall look closer to the intended setup. After that, details such as raised white letters versus a more subdued sidewall can shift the truck toward a sportier or more utility-oriented appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Ford Trucks F-150 Lariat?
Yes, modifications can affect tire fitment on a 2008 Ford Trucks F-150 Lariat. Wheel changes, suspension lifts or drops, altered offsets, and body modifications can all change how a 265/60R18, 275/65R18, or 275/55R20 tire sits in the wheel opening and how it clears during steering travel.
A truck that has been changed from stock should be measured rather than assumed to match original fitment. It helps to verify wheel diameter, wheel width, and clearance at full lock and full suspension movement before choosing a replacement tire, especially when moving between aggressive tread patterns or different wheel packages.
What should I inspect before driving a 2008 Ford Trucks F-150 Lariat on new tires?
Before driving a 2008 Ford Trucks F-150 Lariat on new tires, inspect the wheels for damage, confirm the tire size matches the truck’s actual configuration, and check that all four tires are inflated properly. It is also smart to look at valve stems, lug hardware, tread seating, and any sign of rubbing once the truck is on the ground.
A short initial drive followed by a second inspection can catch problems early. Pay attention to steering feel, vibration, unusual noises, and clearance at turns, then recheck pressure and visible sidewall condition after the first few miles to make sure the installation is settling in normally.
What should I check before a longer drive in a 2008 Ford Trucks F-150 Lariat?
Before a longer drive, confirm that the 2008 Ford Trucks F-150 Lariat has the correct tire size for its sub-model, that pressures are set consistently, and that there are no visible cuts, bulges, cracking, or abnormal wear. Tread depth and any signs of air loss should also be checked before the trip begins.
Longer drives put more heat and load into the tires, so basic condition matters as much as size. It also helps to inspect the spare, make sure the wheels are secure, and consider the truck’s load so the tires are not being asked to do more than their specifications support.
