The 2003 Ford Trucks F-150 Lariat sits in the final years of the tenth-generation F-150, a period when this truck blended everyday pickup utility with more upscale trim and a broader range of two-wheel-drive and four-wheel-drive configurations. That matters at the tire level, because this exact model uses more than one primary radial size depending on sub-model and wheel package. Sizes include 275/60R17, 265/70R17, and 265/70R16, with both 16-inch and 17-inch rims in play. For this truck, the real job is matching the correct size to the exact Lariat configuration, then comparing available tire choices with the intended ride height, appearance, and road or light off-road use in mind.
Which Tire Size Is Right for The 2003 Ford Trucks F-150 Lariat
Three primary tire sizes apply to the 2003 Ford Trucks F-150 Lariat, and the correct one depends on the exact sub-model and wheel diameter. Both 16-inch and 17-inch rims were used, so the first step is confirming whether the truck is a 4x2, 4x4, FX4 H.D., FX4 Super Cab, or FX4 Super Crew Cab, then verifying the wheel setup currently on the vehicle before selecting a tire.
A 275/60R17 tire uses a 275-millimeter section width, a 60-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2003 Ford Trucks F-150 Lariat, this size is part of the truck's primary radial fitment range and is tied to a specific sub-model rather than every Lariat configuration. It has a shorter profile than the 265/70 sizes used elsewhere in the lineup, so buyers should treat it as a configuration-specific fitment rather than a general substitute. This size makes the most sense when the truck still carries the correct 17-inch wheel setup for the matching Lariat application.
A 265/70R17 tire is a metric radial size with a 265-millimeter section width, a 70-series profile, and a 17-inch rim diameter. On the 2003 Ford Trucks F-150 Lariat, it applies to certain four-wheel-drive and FX4-based configurations, making it one of the key fitments to verify by sub-model. Available choices in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and different load-capacity specifications. This is the size to evaluate when the truck uses a 17-inch wheel and the goal is to keep the correct overall fitment type for those Lariat variants.
A 265/70R16 tire keeps the same 265-millimeter section width and 70-series profile as the 17-inch version, but it is built for a 16-inch rim. For the 2003 Ford Trucks F-150 Lariat, this size belongs to specific FX4 configurations, so wheel diameter confirmation is just as important as sub-model identification. BFGoodrich All-Terrain T/A KO2 is available in this size with raised white letter styling and light-truck construction details that may matter to owners comparing use and load needs. It is the appropriate size to review when the truck retains its 16-inch wheel package.
Tire fitment for the 2003 Ford Trucks F-150 Lariat varies by sub-model, and that variation includes both tire size and wheel diameter. Checking the exact configuration matters here because some Lariat versions use 17-inch tires, while others use 16-inch fitments or overlap between the two.

2003 Ford Trucks F-150 Lariat 4x2
The 2003 Ford Trucks F-150 Lariat 4x2 uses its own primary 17-inch tire fitment within the Lariat range. That makes it important to match the tire to the actual two-wheel-drive wheel setup rather than assuming a 4x4 or FX4 size will carry over.
The 2003 Ford Trucks F-150 Lariat 4x4 uses a 17-inch radial fitment that is shared with another FX4-based sub-model. For tire selection, that means the focus shifts from finding the size to comparing the available product specifications that suit how the truck is driven and loaded.
The 2003 Ford Trucks F-150 Lariat FX4 H.D. uses the same primary 17-inch radial tire size as the standard 4x4 Lariat. Buyers should still confirm the wheel package on the truck, then compare tire details such as rim-width compatibility and load specification within that size.
The 2003 Ford Trucks F-150 Lariat FX4 Super Cab uses a 16-inch radial tire size rather than the 17-inch fitments found on other Lariat versions. That makes wheel diameter the first checkpoint before comparing available tires for appearance, use, and compatibility.
The 2003 Ford Trucks F-150 Lariat FX4 Super Crew Cab is the most important configuration to verify because it appears with both 16-inch and 17-inch radial tire fitments. On this truck, checking the actual wheels already installed is essential before selecting any replacement tire.
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.

These FAQs focus on the tire sizes used on the 2003 Ford Trucks F-150 Lariat, how they vary by sub-model, what the size codes mean, and what to inspect before choosing tires for road use or a modified truck.
Tire Size & Fitment
What tire size fits a 2003 Ford Trucks F-150 Lariat?
The 2003 Ford Trucks F-150 Lariat uses three primary tire sizes: 275/60R17, 265/70R17, and 265/70R16. The correct size depends on the exact sub-model, because the 4x2, 4x4, FX4 H.D., FX4 Super Cab, and FX4 Super Crew Cab do not all share the same fitment.
Start by confirming the exact Lariat configuration and the wheel diameter currently on the truck. That matters especially on the FX4 Super Crew Cab, which appears with both 16-inch and 17-inch fitments, so checking the tire sidewall and wheel itself is more reliable than assuming every 2003 Lariat uses the same size.
What size rim does a 2003 Ford Trucks F-150 Lariat use?
A 2003 Ford Trucks F-150 Lariat can use either a 16-inch or 17-inch rim, depending on sub-model and tire size. The 275/60R17 and 265/70R17 sizes use 17-inch rims, while the 265/70R16 size uses a 16-inch rim.
Rim diameter needs to be confirmed before anything else, because a 16-inch tire and a 17-inch tire are not interchangeable. It is also worth checking wheel width when comparing available products, especially on trucks that may have had wheels changed over the years for appearance, off-road use, or aftermarket replacement.
Why does the 2003 Ford Trucks F-150 Lariat have more than one tire size?
More than one tire size appears on the 2003 Ford Trucks F-150 Lariat because the Lariat name covers several configurations, including 4x2, 4x4, FX4 H.D., FX4 Super Cab, and FX4 Super Crew Cab. Those versions were not all built around the same wheel and tire package.
That means tire selection is really a sub-model and wheel-verification question, not just a year-make-model search. A truck that has been modified, had wheels replaced, or moved between trim-related wheel packages can differ from what another Lariat uses, so the best practice is to confirm both the exact model designation and the wheels on the vehicle.
Choosing the Right Tire
What should I consider when choosing a tire for a 2003 Ford Trucks F-150 Lariat?
Begin with the correct primary tire size for the exact truck, then compare construction, wheel diameter, and any load-related details within that size. On this 2003 Ford Trucks F-150 Lariat, the most important distinction is not brand variety so much as making sure the tire matches the truck's 16-inch or 17-inch setup and intended sub-model fitment.
Once the size is confirmed, look at how the truck is actually used. A daily-driven pickup, a lightly used weekend truck, and an FX4 used on rougher surfaces may all lead you to weigh rim-width compatibility, load specification, and tire weight differently when comparing otherwise similar radial options.
What sidewall styles are available for 2003 Ford Trucks F-150 Lariat tires?
The available products shown for the 2003 Ford Trucks F-150 Lariat use RWL sidewalls, which means raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options available in the applicable 265/70R17 and 265/70R16 sizes.
Sidewall style affects the truck's presentation as much as the tread itself, especially on a pickup with a more traditional all-terrain look. If appearance matters, confirm the correct tire size first and then decide whether the raised white letter look suits the way the truck is being restored, maintained, or simply driven.
What brands offer tires for the 2003 Ford Trucks F-150 Lariat?
The available products shown for this 2003 Ford Trucks F-150 Lariat come from BFGoodrich. Those products appear in the All-Terrain T/A KO2 series for the applicable 265/70R17 and 265/70R16 fitments, with radial construction and raised white letter sidewalls.
When product choices are concentrated within one brand and series, the buying decision shifts toward selecting the correct size and comparing specifications within that size. For this truck, that means paying close attention to wheel diameter, rim-width range, and load-related details instead of assuming every tire with a similar appearance serves the same role.
Restoration & Appearance
Which tire should I choose for a period-style 2003 Ford Trucks F-150 Lariat?
A period-style choice for a 2003 Ford Trucks F-150 Lariat starts with the exact size that matches the truck's sub-model and wheel diameter. Because this Lariat range uses 275/60R17, 265/70R17, and 265/70R16 depending on configuration, the right visual stance begins with correct fitment rather than simply choosing a tire that looks close.
Once the proper size is confirmed, sidewall treatment and tread style shape the truck's overall character. A raised white letter all-terrain tire can suit the era and trim presentation well, but buyers chasing exact originality should still compare against vehicle-specific references, photos, or marque guidance before treating any one modern product as historically definitive.
How does tire construction affect the appearance of a restored 2003 Ford Trucks F-150 Lariat?
On the 2003 Ford Trucks F-150 Lariat, the primary fitments are radial tires, so the construction itself already aligns with the truck's model-year era. The visible difference is less about bias-ply versus radial and more about choosing the proper modern size, sidewall treatment, and overall tire character for the exact sub-model.
Appearance can change noticeably when the profile or wheel diameter is wrong, even if the tire still seems close at a glance. Keeping the correct 16-inch or 17-inch fitment and matching the truck's intended look, whether more street-focused or more all-terrain in presentation, usually has a bigger visual effect than brand name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2003 Ford Trucks F-150 Lariat?
Yes, modifications can affect tire fitment on a 2003 Ford Trucks F-150 Lariat. Aftermarket wheels, suspension lifts, lowering changes, altered offsets, or body modifications can all change how a 275/60R17, 265/70R17, or 265/70R16 tire sits within the wheel opening and how it clears during steering and suspension travel.
A truck that no longer has its original wheel setup should be checked carefully before replacement tires are chosen. Confirm the actual wheel diameter and width on the vehicle, then inspect for clearance at full lock and under compression so the selected tire matches the truck as it sits now, not just how it left the factory.
What should I inspect before driving a 2003 Ford Trucks F-150 Lariat on new tires?
Before driving a 2003 Ford Trucks F-150 Lariat on new tires, inspect the wheels, valve stems, lug hardware, and overall wheel condition, then verify the new tires match the correct size for the truck's exact sub-model. It is also smart to check alignment, steering response, and whether the tires seat and balance properly.
A short test drive should be followed by another look for any rubbing, unusual vibration, or pressure loss. Trucks that have been parked for long periods or used in rough conditions also deserve a close look at suspension wear, brake condition, and wheel damage so the new tires are not being asked to compensate for other problems.
How should tires on a 2003 Ford Trucks F-150 Lariat be maintained?
Tires on a 2003 Ford Trucks F-150 Lariat should be maintained with regular pressure checks, visual inspections, and attention to tread wear across the full width of the tire. Uneven wear, cracking, cuts, bulges, or repeated air loss deserve prompt attention, especially on a truck that carries weight, sees occasional off-pavement use, or sits for stretches.
Maintenance also includes watching how the truck is stored and used. Long idle periods, sun exposure, and neglected alignment can shorten tire life even when tread depth still looks acceptable, so owners should inspect tires before road trips, rotate them as appropriate for the setup, and reassess fitment anytime wheels or suspension parts are changed.
