The 2024 Ford Trucks Explorer sits in the modern three-row SUV market with a wide spread of personalities, from everyday family transportation to appearance-focused trims and more performance-oriented ST variants. That broad trim range is why tire fitment is not one-size-fits-all on this Explorer. Depending on sub-model, the primary fitment can be 255/65R18, 265/65R18, 255/55R20, or 275/45R21, and every one of those sizes is a radial. The real choice is less about vintage construction and more about matching the exact trim, wheel diameter, and tire profile, then comparing the available tire options that suit the vehicle’s intended use and presentation.
Which Tire Size Is Right for The 2024 Ford Trucks Explorer
Four primary tire sizes apply to the 2024 Ford Trucks Explorer, and they vary by sub-model and wheel diameter. The first step is identifying the exact trim and confirming whether the vehicle is on 18-inch, 20-inch, or 21-inch wheels, because several Explorer sub-models use different radial sizes that are close in overall diameter but not interchangeable by rim size alone.
255/65R18 is a metric radial size in which 255 identifies the nominal section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2024 Ford Trucks Explorer, this size suits trims that use an 18-inch wheel and a taller sidewall profile than the 20-inch and 21-inch alternatives. That sizing approach tends to preserve a more substantial sidewall look while staying within the Explorer’s modern radial fitment pattern. It is the right size to evaluate only after confirming the exact sub-model and existing wheel setup on the vehicle.
Fit(s): King Ranch, Limited, ST, ST-Line, XLT, and XLT w/Sport Appearance Pkg.
Construction: Radial|Rim: 20 in
255/55R20 is a metric radial size with a 255-millimeter nominal section width, a 55-series profile, radial construction, and a 20-inch rim diameter. On the 2024 Ford Trucks Explorer, this is one of the most widely used sizes across multiple sub-models, making it a common fitment point within the lineup. Its lower profile compared with 18-inch fitments changes the tire’s visual stance and ties it to a larger wheel package. This is the size to focus on when the Explorer already wears 20-inch wheels and the trim falls within the models that use this fitment.
Fit(s): Platinum, ST, ST w/High-Performance Pkg., ST w/Street Pack, and ST-Line
Construction: Radial|Rim: 21 in
275/45R21 is a metric radial size where 275 is the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 21 is the wheel diameter in inches. On the 2024 Ford Trucks Explorer, this size appears on trims that use the largest wheel package in the range, including several ST-related configurations and Platinum. The wider section width and shorter sidewall give it a distinct fitment role within the lineup. Choosing this size starts with confirming that the vehicle is actually equipped for a 21-inch wheel rather than assuming it applies to every Explorer.
265/65R18 is a metric radial tire size with a 265-millimeter nominal section width, a 65-series sidewall, radial construction, and an 18-inch wheel diameter. On the 2024 Ford Trucks Explorer, this size stands apart from the other 18-inch option by using a slightly wider section and a taller overall tire dimension. That gives it a different fitment role within the model range rather than making it a casual substitute for the 255/65R18 size. It should be chosen only when the specific sub-model and wheel setup call for this exact 18-inch fitment.
Tire fitment varies across the 2024 Ford Trucks Explorer range, so checking the exact sub-model is essential before selecting a tire. Some trims use one clearly defined size, while others can be found with more than one factory wheel and tire combination.

2024 Ford Trucks Explorer Base
The 2024 Ford Trucks Explorer Base uses a straightforward 18-inch radial fitment, making tire selection relatively simple once the wheel diameter is confirmed. The main decision is choosing a replacement in the correct size and verifying that the vehicle has not been changed to a different wheel package.
The 2024 Ford Trucks Explorer King Ranch uses a 20-inch radial tire fitment, placing it in the same general sizing family as several other upper trims. Tire selection centers on staying with the proper 20-inch size and checking that the Explorer still wears its intended wheel setup.
The 2024 Ford Trucks Explorer Limited uses a 20-inch radial tire size, so replacement shopping begins with that wheel diameter rather than the 18-inch or 21-inch alternatives found elsewhere in the lineup. That keeps the decision focused on the correct size and the specific tire characteristics desired for everyday road use.
The 2024 Ford Trucks Explorer Platinum uses the 21-inch radial fitment found on the largest wheel package in this model range. Tire selection should stay centered on that exact size and include a careful wheel confirmation before considering any alternative based only on appearance.
The 2024 Ford Trucks Explorer ST can use either a 20-inch or 21-inch radial tire size, so the first step is confirming which wheel package is actually on the vehicle. That makes this trim especially important to verify by measurement or current tire sidewall before ordering replacements.
2024 Ford Trucks Explorer ST w/High-Performance Pkg.
The 2024 Ford Trucks Explorer ST w/High-Performance Pkg. uses a 21-inch radial fitment rather than the smaller wheel setups seen on other trims. Tire selection should follow that exact size and include a quick check that the vehicle still retains the wheel package associated with this configuration.
The 2024 Ford Trucks Explorer ST w/Street Pack uses the 21-inch radial fitment, so tire replacement begins with confirming that larger wheel diameter. The practical decision is selecting the right tire within that size rather than comparing it to the 20-inch fitments used elsewhere in the Explorer range.
The 2024 Ford Trucks Explorer ST-Line can use either a 20-inch or 21-inch radial tire size, which makes wheel verification essential before moving forward. Tire selection depends on the exact wheel package on the vehicle, not just the ST-Line badge on the tailgate.
The 2024 Ford Trucks Explorer Timberline uses a distinct 18-inch radial tire size that differs from the other 18-inch Explorer fitment. That means replacement selection should stay focused on the exact Timberline size rather than assuming any 18-inch Explorer tire will serve the same role.
The 2024 Ford Trucks Explorer XLT can use either an 18-inch or 20-inch radial tire size, so this trim requires wheel confirmation before selecting a replacement. Once that is settled, the choice becomes much more straightforward because each size belongs to a specific wheel diameter.
2024 Ford Trucks Explorer XLT w/Sport Appearance Pkg.
The 2024 Ford Trucks Explorer XLT w/Sport Appearance Pkg. uses a 20-inch radial fitment, distinguishing it from the 18-inch XLT setup. Tire selection should begin with that 20-inch wheel diameter and the exact size already mounted on the vehicle.
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.
Frequently Asked Questions
Explorer tire questions usually come down to trim-specific sizing, wheel diameter, and understanding why one 2024 Ford Trucks Explorer may use a very different radial fitment than another. The answers below focus on size selection, wheel confirmation, appearance choices, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2024 Ford Trucks Explorer?
The 2024 Ford Trucks Explorer uses four primary tire sizes: 255/65R18, 255/55R20, 275/45R21, and 265/65R18. The correct one depends on the exact sub-model and wheel package, and all of these are radial sizes rather than bias-ply fitments.
The key step is matching the tire to the trim and actual wheel diameter on the vehicle. Some Explorer versions share a size, while trims such as ST, ST-Line, and XLT can appear with more than one valid fitment, so reading the current sidewall and confirming the wheel before replacement helps avoid an expensive mismatch.
What size rim does a 2024 Ford Trucks Explorer use?
A 2024 Ford Trucks Explorer can use 18-inch, 20-inch, or 21-inch rims, depending on sub-model. The tire sizes align with those wheel diameters: 255/65R18 and 265/65R18 fit 18-inch rims, 255/55R20 fits a 20-inch rim, and 275/45R21 fits a 21-inch rim.
That variation makes wheel confirmation just as important as tire-size confirmation. Even when two Explorer sizes have a similar overall diameter, the rim diameter is not interchangeable, so the safest approach is to verify the marking on the current tire and physically confirm the wheel size before selecting a replacement.
Why does the 2024 Ford Trucks Explorer have more than one tire size?
The 2024 Ford Trucks Explorer spans multiple trims with different wheel packages, so it uses more than one tire size across the lineup. Base and Timberline models stay with 18-inch fitments, several trims use 20-inch wheels, and Platinum and some ST-based versions move to a 21-inch package.
That means tire choice starts with the exact configuration, not just the model name. An Explorer badge alone is not enough to choose the right tire, especially on trims that can be equipped with either 18-inch, 20-inch, or 21-inch wheels, so checking the sub-model and current tire sidewall is the practical first move.
Choosing the Right Tire
What should I consider when choosing a 2024 Ford Trucks Explorer tire?
Start with the exact tire size and wheel diameter your 2024 Ford Trucks Explorer uses, because the model range includes four different radial fitments. After that, compare the tire’s profile and intended use, since an 18-inch Explorer setup serves a different role than the lower-profile 20-inch and 21-inch combinations.
A sensible choice also takes the vehicle’s actual condition into account. Check whether the Explorer still has its original wheel package, whether suspension height has changed, and whether the new tire’s dimensions match the trim’s intended fitment, especially on XLT, ST, and ST-Line models that can appear with more than one size.
How do I choose between the available 18-inch, 20-inch, and 21-inch tires for a 2024 Ford Trucks Explorer?
The correct choice is not a matter of preference alone, because each 2024 Ford Trucks Explorer tire size belongs to a specific wheel diameter and trim combination. An 18-inch tire cannot simply replace a 20-inch or 21-inch fitment, and the 18-inch Explorer sizes are not automatically interchangeable with one another either.
Selection becomes easier once the wheel diameter is verified. From there, compare only the tires built for that exact size, and keep the search focused on the Explorer’s intended use, whether that means routine road driving, preserving the trim’s original visual stance, or maintaining compatibility with its present wheel and suspension setup.
How do I choose between the available 2024 Ford Trucks Explorer tire sizes on XLT, ST, and ST-Line models?
On 2024 Ford Trucks Explorer XLT, ST, and ST-Line trims, the right tire size depends on the wheel package installed on the vehicle. XLT can use 255/65R18 or 255/55R20, while ST and ST-Line can use 255/55R20 or 275/45R21.
That makes wheel verification more important than trim name alone. Reading the current tire sidewall, checking the wheel diameter directly, and confirming that the vehicle has not been changed to an aftermarket setup will narrow the choice quickly and prevent ordering a tire that matches the badge but not the actual wheel package.
Restoration & Appearance
Does correct tire fitment matter for the appearance of a 2024 Ford Trucks Explorer?
Yes, the correct tire fitment has a noticeable effect on how a 2024 Ford Trucks Explorer sits and presents itself. The model’s 18-inch, 20-inch, and 21-inch combinations use different sidewall proportions, so the vehicle’s overall visual balance changes when the intended size is replaced with something outside its trim-specific fitment.
Appearance matters, but it should stay tied to the proper wheel and tire relationship. A Base, Timberline, Platinum, or ST-based Explorer can look quite different from the factory, so choosing the size that belongs to the actual trim helps preserve the vehicle’s intended stance while keeping the fitment process grounded in correct dimensions.
How does tire profile affect the look of a 2024 Ford Trucks Explorer?
Tire profile changes the visual character of a 2024 Ford Trucks Explorer even when overall diameter stays relatively close. The 18-inch sizes use a taller sidewall presentation, while the 20-inch and 21-inch fitments pair larger wheels with shorter sidewalls for a different stance and wheel-to-tire proportion.
That difference is one reason trim-specific sizing matters. Moving away from the intended profile can alter how much sidewall is visible, how full the wheel opening appears, and how the Explorer visually matches its trim package, so appearance-minded owners should confirm the exact wheel and size before making a change.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Ford Trucks Explorer?
Yes, modifications can affect tire fitment on a 2024 Ford Trucks Explorer even when the tire size seems close to stock. Aftermarket wheels, changes in wheel width or offset, suspension lowering, lift changes, and body alterations can all change clearance around the fenders, struts, and steering components.
The practical answer is to verify the actual setup before replacing tires. An Explorer that began life with 18-inch, 20-inch, or 21-inch wheels may no longer match its original trim-based fitment, so checking wheel diameter, current size markings, and available clearance helps keep the next tire choice aligned with the vehicle as it sits today.
What should I inspect before driving a 2024 Ford Trucks Explorer on new tires?
Before driving a 2024 Ford Trucks Explorer on new tires, inspect the wheel diameter and tire size for a correct match, then check inflation pressure, lug torque, tread seating, and visible clearance at the fenders and suspension. A quick look for uneven ride height or rubbing marks is also worthwhile after installation.
Collector-car storage concerns are less central here than setup accuracy and condition, especially on trims that can use more than one tire size. A short, careful road test followed by a second inspection can reveal contact issues, vibration, or air loss early, before the Explorer is put into regular service or longer highway use.
What should I check before a longer drive in a 2024 Ford Trucks Explorer?
Before a longer drive, confirm that the 2024 Ford Trucks Explorer is on the correct tire size for its trim and wheel package, then inspect pressure, tread condition, sidewalls, and any signs of cuts, bulges, cracking, or irregular wear. The spare, if equipped, also deserves a pressure and condition check.
Longer trips put more demand on any tire issue that has been easy to ignore around town. It is smart to check for slow air loss, verify that the alignment feels stable, and make sure no rubbing appears at full steering lock, especially if the Explorer has had wheel, suspension, or appearance-package changes over time.
