The 2008 Ford Trucks Expedition sits in the full-size SUV era when utility, towing capacity, and family road-trip comfort all had to live in one package. Extended-length EL models, trim-specific wheel packages, and specialty editions mean tire selection is more configuration-specific here than it first appears. This Expedition uses radial tires, with fitments in 265/70R17, 255/70R18, and 275/55R20 depending on sub-model and wheel setup. That makes the real decision less about vintage construction and more about confirming the exact trim and rim diameter first. Once that is settled, the focus shifts to the right size, intended use, and whether a more street-oriented or all-terrain look suits the vehicle best.
Which Tire Size Is Right for The 2008 Ford Trucks Expedition
Three tire sizes apply to the 2008 Ford Trucks Expedition, and they vary by sub-model and wheel diameter. The first step is confirming the exact trim and whether the vehicle is on 17-inch, 18-inch, or 20-inch wheels, since that determines whether it uses 265/70R17, 255/70R18, or 275/55R20. All three are radial fitments, so the choice centers on matching the vehicle's wheel setup and intended use rather than choosing between bias-ply and radial construction.
Fit(s): EL Eddie Bauer, EL King Ranch, EL Limited, EL XLT, Eddie Bauer, King Ranch, Limited, and XLT
Construction: Radial|Rim: 18 in
255/70R18 is a metric radial size in which 255 identifies the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2008 Ford Trucks Expedition, this size serves trims that use an 18-inch wheel and keeps the fitment in a modern SUV sizing format. It represents a middle ground within this Expedition lineup, sitting between the 17-inch and 20-inch applications. This is the size to evaluate when the vehicle has 18-inch wheels and the goal is to stay with the proper wheel diameter and trim-specific fitment.
Fit(s): EL Eddie Bauer, EL King Ranch, EL Limited, Eddie Bauer, Funkmaster Flex Edition, King Ranch, and Limited
Construction: Radial|Rim: 20 in
275/55R20 is a metric radial size with a 275-millimeter nominal section width, a 55-series profile, radial construction, and a 20-inch rim requirement. For the 2008 Ford Trucks Expedition, this fitment belongs to sub-models equipped with 20-inch wheels, including the Funkmaster Flex Edition and certain upper trims. Its sizing format reflects a larger-wheel package than the 17-inch and 18-inch alternatives used elsewhere in the Expedition range. This is the correct size to investigate only after confirming the vehicle is actually running the 20-inch wheel setup, since rim diameter is the key fitment divider.
265/70R17 is a metric radial size where 265 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 17 indicates rim diameter in inches. On the 2008 Ford Trucks Expedition, it is used on 17-inch-wheel configurations such as the XLT SSV and certain XLT, Eddie Bauer, and EL XLT applications. Available products in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and 7.0- to 9.0-inch rim-width compatibility. This size deserves a closer look when the Expedition is used on rougher roads or when an all-terrain presentation is part of the plan.
Sub-model fitment on the 2008 Ford Trucks Expedition is not one-size-fits-all. Several trims share more than one possible tire size, so identifying the exact sub-model and confirming the wheel diameter on the vehicle are the two most important steps before choosing tires.

2008 Ford Trucks Expedition EL Eddie Bauer
The 2008 Ford Trucks Expedition EL Eddie Bauer uses radial tires and can be found with either the 255/70R18 or 275/55R20 fitment. Tire selection starts with confirming whether the vehicle is on 18-inch or 20-inch wheels, then choosing within the appropriate size for the way the SUV is driven and presented.
The 2008 Ford Trucks Expedition EL King Ranch uses radial tire fitments that span both 255/70R18 and 275/55R20 applications. That makes wheel confirmation essential before ordering, since the right tire depends on whether the vehicle carries the 18-inch or 20-inch setup.
The 2008 Ford Trucks Expedition EL Limited shares the same two radial fitment paths as other upper EL trims, using either 255/70R18 or 275/55R20. The practical decision is to verify the actual wheel diameter on the vehicle and then select a tire that matches both the size and the Expedition's intended road use.
The 2008 Ford Trucks Expedition EL XLT can use either 255/70R18 or 265/70R17 radial tires depending on wheel setup. That means this trim needs more than a trim-name check alone, since the final choice depends on whether the Expedition is equipped with 17-inch or 18-inch wheels.
The 2008 Ford Trucks Expedition Eddie Bauer has the widest fitment spread in this group, with 255/70R18, 265/70R17, and 275/55R20 all appearing across radial applications. Tire selection for this trim should begin with the wheel currently on the vehicle, especially if it has been changed from its original-style setup.
2008 Ford Trucks Expedition Funkmaster Flex Edition
The 2008 Ford Trucks Expedition Funkmaster Flex Edition uses the 275/55R20 radial size. With only one primary fitment tied to this edition, the main job is confirming the 20-inch wheel setup and then choosing a tire that suits the vehicle's appearance and road-use priorities.
The 2008 Ford Trucks Expedition King Ranch uses radial tires in either 255/70R18 or 275/55R20 depending on wheel package. Picking the right tire starts with wheel diameter, since the trim name alone does not narrow the fitment to one size.
The 2008 Ford Trucks Expedition Limited follows the same two-size radial pattern as several other premium trims, using either 255/70R18 or 275/55R20. Verifying the actual wheel on the vehicle matters more than assuming one fitment, particularly on SUVs that may have seen wheel changes over time.
The 2008 Ford Trucks Expedition XLT uses radial tires and can be equipped with either 255/70R18 or 265/70R17. Choosing correctly means checking the wheel diameter on the vehicle first, then comparing tire options within that confirmed size.
The 2008 Ford Trucks Expedition XLT SSV uses the 265/70R17 radial size. That makes the fitment path more straightforward, and the next step becomes comparing available 17-inch tire options with the right load capability, sidewall style, and intended-use character.
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.

Common 2008 Ford Trucks Expedition tire questions usually come down to trim-specific size selection, wheel diameter, and how to choose the right tire within the correct fitment. This section also covers product choice, appearance, modifications, and road-use checks.
Tire Size & Fitment
What tire size fits a 2008 Ford Trucks Expedition?
The 2008 Ford Trucks Expedition uses three radial tire sizes: 265/70R17, 255/70R18, and 275/55R20. The correct one depends on the exact sub-model and the wheel diameter on the vehicle, so there is not one universal Expedition size for the entire model range.
A quick trim check helps, but the safest next step is confirming whether the SUV is on 17-inch, 18-inch, or 20-inch wheels before choosing a tire. That matters even more on Expeditions that may have had wheels changed over time, since the right tire must match the actual rim diameter in use.
What size rim does a 2008 Ford Trucks Expedition use?
A 2008 Ford Trucks Expedition can use 17-inch, 18-inch, or 20-inch rims, depending on sub-model and wheel package. Those rim diameters align with the vehicle's three tire sizes: 265/70R17 for 17-inch wheels, 255/70R18 for 18-inch wheels, and 275/55R20 for 20-inch wheels.
Rim diameter is the first thing to verify because it immediately narrows the tire search to the correct size family. Looking at the current sidewall marking or measuring the wheel directly is a better guide than relying on trim assumptions alone, especially on used SUVs with aftermarket or replacement wheels.
Why does the 2008 Ford Trucks Expedition have more than one tire size?
The 2008 Ford Trucks Expedition spans multiple trims and wheel packages, which is why it uses more than one tire size. Some sub-models share two possible fitments, and the Eddie Bauer trim appears with all three size paths: 265/70R17, 255/70R18, and 275/55R20.
That means tire selection is tied to the vehicle's exact configuration rather than the Expedition name alone. Checking the sub-model helps, but confirming the wheel diameter on the truck matters just as much, because a trim can still appear with more than one correct fitment depending on how it was equipped.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2008 Ford Trucks Expedition?
Start by confirming that 265/70R17 is the actual fitment for the Expedition's wheel and sub-model. In this size, available BFGoodrich All-Terrain T/A KO2 products share radial construction and raised white letter sidewalls, but they differ in load specification, weight, and maximum load capacity.
The next step is matching the tire to how the SUV is used. An Expedition that sees cargo, towing, rougher roads, or heavier-duty service may call for closer attention to load capacity and inflation range, while any selection should still be checked against the wheel's width and the vehicle's clearance.
What sidewall styles are available for 2008 Ford Trucks Expedition tires?
Among the currently covered 265/70R17 Expedition options, the available sidewall style is RWL, or raised white letter. That gives the tire a more traditional truck and SUV presentation than a plain blackwall, while still staying within the correct radial fitment for 17-inch-wheel applications.
Sidewall style is largely an appearance decision, but it can shape the overall character of the vehicle. A raised white letter look suits owners who want a more rugged or classic SUV visual theme, while the first priority should still be making sure the tire size, load rating, and wheel compatibility are correct.
What brands offer tires for the 2008 Ford Trucks Expedition?
Current product coverage for the 2008 Ford Trucks Expedition includes BFGoodrich in the 265/70R17 size. The available tire series is the All-Terrain T/A KO2, which places the focus on an all-terrain radial option for Expeditions using the 17-inch wheel fitment.
Brand matters, but it should not be the only filter. The better comparison is whether the tire is offered in the right size for the vehicle, whether its load specification matches the Expedition's intended use, and whether the wheel width and overall setup support that specific tire properly.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Ford Trucks Expedition?
A period-style 2008 Ford Trucks Expedition starts with the correct trim-specific size and wheel diameter rather than with a vintage construction question, since this model uses radial tires throughout. For 17-inch applications, the 265/70R17 fitment keeps the vehicle in its proper size family while allowing a truck-oriented all-terrain presentation.
Appearance choices should follow the way the vehicle is being preserved or presented. An owner aiming for a showroom-era look may want to stay close to the original wheel diameter and tire profile, while a more utility-focused Expedition can lean into tread and sidewall character without straying from the correct fitment.
How does tire construction affect the appearance of a restored 2008 Ford Trucks Expedition?
Construction is less of an appearance divider on a 2008 Ford Trucks Expedition than it would be on an older collector vehicle because the primary fitments are already radial. The visual differences come more from tire profile, wheel diameter, tread character, and sidewall treatment than from choosing between bias-ply and radial construction.
That makes size accuracy especially important on a restoration-minded Expedition. Staying with the proper 17-inch, 18-inch, or 20-inch fitment for the specific sub-model helps preserve the vehicle's intended stance, while sidewall styling and tread pattern can then fine-tune whether the finished look feels stock-minded or more aggressive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Ford Trucks Expedition?
Yes. Wheel swaps, suspension changes, lowering, lift kits, and even replacement wheels with different widths can all affect tire fitment on a 2008 Ford Trucks Expedition. That matters because this model already spans 17-inch, 18-inch, and 20-inch fitments across its sub-model range.
A modified Expedition should be checked for actual wheel diameter, wheel width, and clearance at the fenders and steering components before selecting tires. Even when the sidewall shows a familiar Expedition size, changes elsewhere on the vehicle can alter what works comfortably in real-world driving.
What should I inspect before driving a 2008 Ford Trucks Expedition on new tires?
Before putting a 2008 Ford Trucks Expedition into regular use on new tires, inspect the wheel condition, confirm the lug hardware is correct, and make sure the tire size matches the wheel diameter actually on the vehicle. Tire pressure, visible clearance, and any signs of rubbing should also be checked right away.
A short initial drive is useful for spotting vibration, pull, or contact issues before the vehicle goes on a longer trip. It also helps to recheck inflation after the first drive and keep an eye on uneven wear, especially on an SUV that may have alignment changes, towing duty, or older suspension parts.
How should tires on a 2008 Ford Trucks Expedition be maintained?
Tires on a 2008 Ford Trucks Expedition should be maintained with regular pressure checks, visual inspections for cuts or sidewall damage, and close attention to tread wear. Because this is a heavy full-size SUV, even a correct-size tire needs to be kept in sound condition to deliver stable everyday road use.
Low-use vehicles still need attention, since age, long periods of parking, and environmental exposure can affect tire condition even when tread looks acceptable. Keeping the Expedition stored away from prolonged sunlight and checking for cracking, bulges, or air loss before longer drives helps prevent problems that are easy to miss.
