The 2018 Ford Trucks Expedition sits in the modern full-size SUV segment where family hauling, towing, and long-distance road use all matter, and trim level has a direct impact on wheel and tire selection. On this Expedition, the tire decision starts with identifying the exact sub-model because three radial sizes are used: 275/65R18, 275/55R20, and 285/45R22. That means the real choice is not only size, but also confirming wheel diameter and deciding whether the vehicle is set up for an 18-inch, 20-inch, or 22-inch package. For owners replacing tires, appearance, load capability, and the actual wheel setup all deserve a careful look before ordering.
Which Tire Size Is Right for The 2018 Ford Trucks Expedition
The 2018 Ford Trucks Expedition uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel package. All three are radial sizes, but they span 18-inch, 20-inch, and 22-inch rims, so confirming the vehicle's actual wheel diameter is the first step before comparing tires or narrowing down replacement options.
Fit(s): Limited, Max Limited, Max XL, Max XLT, XL, and XLT
Construction: Radial|Rim: 20 in
275/55R20 is a modern metric radial size where 275 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2018 Ford Trucks Expedition, this size represents one of the standard modern SUV fitments used on a 20-inch wheel package. It is important for owners of Limited, Max Limited, XL, XLT, Max XL, and Max XLT models to confirm that the vehicle still carries its intended 20-inch wheels. This size makes sense when the Expedition is equipped for the 20-inch setup rather than the 18-inch or 22-inch alternatives.
Fit(s): Limited, Max Limited, Max Platinum, and Platinum
Construction: Radial|Rim: 22 in
285/45R22 is a metric radial size with a 285-millimeter section width, a 45-series profile, radial construction, and a 22-inch rim diameter. For the 2018 Ford Trucks Expedition, this size belongs to models equipped with the larger 22-inch wheel package, including Platinum and certain Limited variants. Its lower-profile format gives it a distinctly different fitment context than the 18-inch and 20-inch sizes used elsewhere in the range. Choosing this size starts with verifying that the Expedition actually has 22-inch wheels and has not been changed from its original trim-level wheel setup.
275/65R18 is a metric radial size that uses a 275-millimeter section width, a 65-series profile, radial construction, and an 18-inch rim diameter. On the 2018 Ford Trucks Expedition, this size is associated with XL, XLT, Max XL, and Max XLT configurations equipped with the 18-inch wheel package. Available product choice in this size includes the BFGoodrich All-Terrain T/A KO2 with raised white letter styling, an All Terrain TA KO2 series designation, and a rim-width range of 7.5 to 9.5 inches. It is the size to evaluate when the Expedition is set up for 18-inch wheels and an all-terrain-oriented replacement is under consideration.
Tire fitment on the 2018 Ford Trucks Expedition varies by sub-model and wheel package rather than staying uniform across the lineup. Checking the exact trim matters because some versions use two possible sizes, while others are tied to a single 22-inch fitment.

2018 Ford Trucks Expedition Limited
The 2018 Ford Trucks Expedition Limited uses radial tire fitments tied to either a 20-inch or 22-inch wheel setup. Tire selection starts with confirming which wheel package is on the vehicle, then choosing a replacement that matches that diameter and intended use.
The 2018 Ford Trucks Expedition Max Limited also spans two radial fitment paths, depending on whether it carries 20-inch or 22-inch wheels. That makes wheel verification especially important before comparing replacement tires or judging profile differences between available sizes.
The 2018 Ford Trucks Expedition Max Platinum uses a single radial fitment centered on the 22-inch wheel package. Owners shopping this sub-model can focus less on alternate primary sizes and more on confirming the existing wheel setup and replacement tire specification.
The 2018 Ford Trucks Expedition Max XL can be equipped with either an 18-inch or 20-inch radial tire package. Choosing the right replacement means checking the actual wheel diameter on the vehicle first, especially if wheels may have been changed since new.
The 2018 Ford Trucks Expedition Max XLT shares the same two-size fitment pattern found on other non-Platinum variants, using either 18-inch or 20-inch radial tires. Buyers should match the tire to the vehicle's present wheel package before comparing tread style or road-use priorities.
The 2018 Ford Trucks Expedition Platinum uses the 22-inch radial fitment rather than the 18-inch or 20-inch alternatives seen elsewhere in the range. For this sub-model, the main decision is selecting the right replacement within that wheel diameter rather than sorting through multiple primary sizes.
The 2018 Ford Trucks Expedition XL can use either an 18-inch or 20-inch radial tire setup. That means owners should verify the actual wheels on the SUV before ordering tires, then compare replacement options that suit the vehicle's everyday driving or light truck use.
The 2018 Ford Trucks Expedition XLT follows the same pattern as the XL, with radial fitment based on either 18-inch or 20-inch wheels. A correct tire choice begins with wheel confirmation, followed by checking the tire's intended character, dimensions, and compatibility with the vehicle's setup.
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 2018 Ford Trucks Expedition Tires for Sale

These FAQs focus on 2018 Ford Trucks Expedition tire sizes, wheel-diameter differences across sub-models, available 18-inch product choices, and the fitment checks that matter before replacing tires on a full-size SUV.
Tire Size & Fitment
What tire size fits a 2018 Ford Trucks Expedition?
The 2018 Ford Trucks Expedition uses three primary tire sizes: 275/65R18, 275/55R20, and 285/45R22. All are radial sizes, but they do not apply across the lineup in the same way, because fitment changes by sub-model and wheel package.
The practical first step is to identify the exact Expedition trim and confirm whether the vehicle has 18-inch, 20-inch, or 22-inch wheels. That matters even more on used SUVs, where wheel changes are common. The correct replacement tire should match the wheel diameter already on the vehicle and should also be checked for overall fit, load suitability, and clearance.
What size rim does a 2018 Ford Trucks Expedition use?
A 2018 Ford Trucks Expedition can use 18-inch, 20-inch, or 22-inch rims depending on the sub-model and wheel package. The tire sizes correspond directly to those diameters: 275/65R18 for 18-inch rims, 275/55R20 for 20-inch rims, and 285/45R22 for 22-inch rims.
Wheel diameter should be confirmed before doing anything else, because the three tire sizes are not meant for the same rim. Looking only at the model year is not enough when the Expedition has multiple trim-based wheel packages. A quick check of the sidewall and the actual wheel size helps prevent ordering the wrong diameter and narrows the search to the right tire category.
Why does the 2018 Ford Trucks Expedition have more than one tire size?
The 2018 Ford Trucks Expedition has more than one tire size because different sub-models and wheel packages were equipped with different rim diameters. Some trims can use either 18-inch or 20-inch setups, while Platinum and Max Platinum models use the 22-inch fitment.
That means trim name alone may not settle the question unless the wheel package is also verified. Limited and Max Limited models, for example, span both 20-inch and 22-inch fitments, while XL and XLT variants can use 18-inch or 20-inch sizes. Matching the tire to the vehicle's actual wheels is more important than assuming all Expeditions from 2018 share the same replacement size.
Choosing the Right Tire
What should I consider when choosing a 275/65R18 tire for a 2018 Ford Trucks Expedition?
A 275/65R18 tire for the 2018 Ford Trucks Expedition should first match the vehicle's actual 18-inch wheel setup. In the available product range, this size includes the BFGoodrich All-Terrain T/A KO2 radial, which carries a 3,415-pound maximum load at 80 psi, raised white letter sidewall styling, and a 7.5- to 9.5-inch rim-width range.
Those details help narrow the decision beyond simple size. An all-terrain pattern may suit an Expedition that sees rougher roads or truck-style use, while rim-width compatibility should be checked against the wheels already on the vehicle. Sidewall appearance also matters, since raised white letters create a different look than a more understated black sidewall tire would.
What sidewall styles are available for 2018 Ford Trucks Expedition tires?
Within the currently available product coverage for the 2018 Ford Trucks Expedition, the visible sidewall style is RWL, or raised white letter, in 275/65R18. That gives the 18-inch fitment a more truck-oriented presentation than a plain blackwall tire.
Sidewall style matters mostly for appearance, but it can also affect how closely the tire matches the look you want from the Expedition. A raised white letter tire stands out more and often suits owners who prefer a bolder SUV or light-truck character. It still needs to be the correct size for the sub-model and wheel diameter before appearance becomes the deciding factor.
What brands offer tires for the 2018 Ford Trucks Expedition?
The currently covered product selection for the 2018 Ford Trucks Expedition includes BFGoodrich in 275/65R18. The available tire is the BFG All-Terrain T/A KO2, a radial all-terrain design intended for the Expedition's 18-inch wheel fitment.
Brand is only one part of the decision. It still makes sense to confirm that the Expedition uses the 18-inch setup before focusing on the BFGoodrich option, since other trims may require 20-inch or 22-inch tires instead. Once size and wheel diameter are confirmed, comparing series type, sidewall treatment, load specification, and rim-width compatibility becomes much more useful.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Ford Trucks Expedition restoration or refresh?
Correct tire fitment matters even on a modern full-size SUV like the 2018 Ford Trucks Expedition because the vehicle was offered with multiple wheel diameters and matching tire sizes. Using the wrong diameter or profile can change the look of the vehicle and complicate replacement planning.
For an appearance-focused refresh, the best starting point is matching the Expedition's actual trim-level wheel package and keeping the tire size consistent with that setup. That preserves the intended stance more closely than mixing sizes across 18-inch, 20-inch, and 22-inch applications. If exact as-delivered appearance matters, original sales literature or marque-specific references can help guide the final choice.
How does tire choice affect the appearance of a 2018 Ford Trucks Expedition?
Tire choice has a noticeable effect on a 2018 Ford Trucks Expedition because the vehicle uses three different fitment profiles tied to 18-inch, 20-inch, and 22-inch wheels. A 22-inch setup presents a different visual balance than an 18-inch package, and sidewall treatment also changes the overall character.
The available 275/65R18 product uses raised white letters, which gives the Expedition a more truck-oriented look than a quieter sidewall style. Owners aiming for a clean trim-matched presentation usually start by preserving the correct wheel diameter for the sub-model, then choosing a tire style that complements how the SUV is being refreshed, maintained, or visually updated.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Ford Trucks Expedition?
Yes, modifications can affect tire fitment on a 2018 Ford Trucks Expedition. Aftermarket wheels, suspension changes, leveling kits, lowering, or body alterations can all change the space available for the tire and may also alter which wheel diameter is currently on the vehicle.
That is why the sidewall size alone should not be the only checkpoint on a modified Expedition. Wheel width, offset, steering clearance, and fender clearance all deserve attention before replacing tires. Even when the SUV started life with one of the standard 18-inch, 20-inch, or 22-inch packages, later changes can shift what actually works on the vehicle now.
What should I inspect before driving a 2018 Ford Trucks Expedition on new tires?
Before driving a 2018 Ford Trucks Expedition on new tires, inspect the wheels for correct diameter and condition, confirm that the installed tire size matches the vehicle's wheel package, and look over valve stems, lug hardware, and visible suspension components. Tire pressure should also be set properly for the installed tire.
A short clearance check is worthwhile before regular road use, especially if the Expedition has aftermarket wheels or has been modified. Turn the steering from lock to lock and look for any rubbing points. It also helps to recheck pressure and lug torque after the first drive, since a newly mounted tire and wheel assembly can settle slightly in initial use.
How often should tires on a 2018 Ford Trucks Expedition be inspected?
Tires on a 2018 Ford Trucks Expedition should be inspected regularly, not just when replacement is overdue. A quick visual check for uneven wear, cuts, punctures, cracking, bulges, and low pressure helps catch issues early, especially on a large SUV that may carry passengers, cargo, or tow-duty loads.
Monthly checks are a sensible habit, with extra attention before longer trips. It also pays to inspect the tires anytime the Expedition starts pulling, vibrating, or showing unusual wear patterns. Keeping an eye on tread condition and air loss is particularly important when the vehicle has multiple possible wheel packages, since maintaining the correct size and proper inflation supports predictable road manners.
