The 2004 Ford Trucks F-250 Super Duty sits in the era when heavy-duty pickups were expected to do real work while still offering increasingly distinct trim personalities, from straightforward XL and XLT models to the more specialized Harley-Davidson Edition and King Ranch. Tire fitment on this truck is not one-size-fits-all, with 235/85R16, 265/75R16, and 275/65R20 radial sizes appearing across the lineup. That makes wheel diameter and sub-model especially important, since the truck can be on either 16-inch or 20-inch rims. Once the correct size is confirmed, the decision shifts toward load capacity, sidewall styling, and how the truck is actually used.
Which Tire Size Is Right for The 2004 Ford Trucks F-250 Super Duty
Three tire sizes apply to the 2004 Ford Trucks F-250 Super Duty, and the right one depends on the exact sub-model and wheel setup. Because this truck uses both 16-inch and 20-inch rim diameters, the first step is confirming the truck's current wheels before choosing a tire. After that, selection comes down to the proper metric radial size, load capacity, rim-width compatibility, and the intended mix of work, towing, and road use.
Fit(s): Harley-Davidson Edition, Lariat, XL, and XLT
Construction: Radial|Rim: 16 in
265/75R16 is a metric radial size in which 265 represents nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 16 is the rim diameter in inches. On the 2004 Ford Trucks F-250 Super Duty, this is one of the main 16-inch fitments and appears on several sub-models. Available choices in this size include BFGoodrich's All-Terrain T/A KO2 with raised white letter styling. It is a strong size to evaluate when the truck already has 16-inch wheels and the goal is a balanced heavy-duty pickup fitment with an all-terrain character.
275/65R20 is a metric radial size that uses a 275-millimeter nominal section width, a 65-series profile, and a 20-inch rim diameter. For the 2004 Ford Trucks F-250 Super Duty, this size is tied to a 20-inch wheel setup rather than the more common 16-inch fitments, so it serves a specific role within the lineup. BFGoodrich offers this size in the All-Terrain T/A KO2 series with an RBL sidewall treatment. It should be considered only after confirming that the truck is actually equipped for a 20-inch tire and that the wheel width matches the tire's requirements.
235/85R16 is a metric radial size where 235 is the nominal section width in millimeters, 85 is the aspect ratio, R marks radial construction, and 16 identifies the rim diameter. On the 2004 Ford Trucks F-250 Super Duty, this is another 16-inch fitment used on selected sub-models. In available product choices, BFGoodrich offers this size in the All-Terrain T/A KO2 line with raised white letter styling. This size is worth evaluating when the truck uses the narrower 16-inch wheel and the goal is to stay with the correct heavy-duty fitment for that particular configuration.
Sub-model fitment on the 2004 Ford Trucks F-250 Super Duty is not the same across the board, and some trims carry more than one tire size depending on wheel setup. Checking the exact sub-model is important because this truck spans both 16-inch and 20-inch rim applications.

2004 Ford Trucks F-250 Super Duty Harley-Davidson Edition
The 2004 Ford Trucks F-250 Super Duty Harley-Davidson Edition uses radial tire fitments in either 265/75R16 or 275/65R20, making wheel diameter the key detail to confirm first. Once the truck's current rims are verified, tire selection becomes a matter of matching the proper size and comparing the available all-terrain product specifications.
The 2004 Ford Trucks F-250 Super Duty King Ranch uses the 235/85R16 radial size. That keeps tire selection fairly straightforward, with the main focus shifting to a 16-inch wheel match, load capacity, and whether the truck's use leans more toward work duty or general road miles.
The 2004 Ford Trucks F-250 Super Duty Lariat uses the 265/75R16 radial size. For this sub-model, the key decision is less about multiple fitments and more about choosing a tire that matches the truck's wheel width, load demands, and preferred sidewall presentation.
The 2004 Ford Trucks F-250 Super Duty XL can use either 235/85R16 or 265/75R16 in radial construction. That means the owner should confirm the truck's existing wheel and current setup before selecting a replacement, especially if the truck has seen work-truck wheel changes over time.
The 2004 Ford Trucks F-250 Super Duty XLT can use either 235/85R16 or 265/75R16 radial tires. Because both are 16-inch sizes with different proportions, selecting the right one starts with verifying the wheel and the truck's present fitment rather than assuming one size applies to every XLT.
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 2004 Ford Trucks F-250 Super Duty Tires for Sale
Available 2004 Ford Trucks F-250 Super Duty tire choices center on BFGoodrich All-Terrain T/A KO2 radials in the three supported sizes. The main comparisons are 16-inch versus 20-inch fitment, rim-width range, load capacity, and sidewall treatment, with RWL and RBL styles both represented.
Owners of a 2004 Ford Trucks F-250 Super Duty usually need to sort out the exact tire size, wheel diameter, and trim-specific fitment before comparing product details. These FAQs focus on sizing, rim match, available radial choices, appearance, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2004 Ford Trucks F-250 Super Duty?
A 2004 Ford Trucks F-250 Super Duty uses one of three radial tire sizes: 235/85R16, 265/75R16, or 275/65R20. The correct size depends on the exact sub-model and wheel setup, not just the model name. King Ranch uses 235/85R16, Lariat uses 265/75R16, Harley-Davidson Edition can use 265/75R16 or 275/65R20, and XL and XLT can use either 235/85R16 or 265/75R16.
That means the first step is confirming the truck's actual rims and current configuration before ordering tires. Two of the fitments share a 16-inch rim diameter but use different proportions, while the 275/65R20 fitment requires a 20-inch wheel. On trucks that have seen wheel changes, suspension work, or mixed replacement history, checking the size on the sidewall and measuring wheel diameter is especially important.
What size rim does a 2004 Ford Trucks F-250 Super Duty use?
A 2004 Ford Trucks F-250 Super Duty uses either a 16-inch or 20-inch rim, depending on the tire size and sub-model setup. The 235/85R16 and 265/75R16 fitments both use 16-inch rims, while the 275/65R20 fitment uses a 20-inch rim. Those rim diameters are not interchangeable just because the truck itself is the same year and model family.
Verifying rim diameter should come before comparing tread style or load specifications. A 16-inch tire will not mount on a 20-inch wheel, and the reverse is just as true. Rim width also matters once the diameter is confirmed, since the available tires in these sizes carry different wheel-width ranges that should match the truck's existing wheels.
Why does the 2004 Ford Trucks F-250 Super Duty have more than one tire size?
The 2004 Ford Trucks F-250 Super Duty has more than one tire size because fitment varies by sub-model and wheel package. Across the lineup, the truck appears with 235/85R16, 265/75R16, and 275/65R20 radial tires. Harley-Davidson Edition is the trim with both 16-inch and 20-inch fitments, while XL and XLT can use two different 16-inch sizes.
That variation makes it risky to choose a tire by year alone. The safest path is to identify the sub-model, then confirm the wheel diameter and the size currently on the truck. On a heavy-duty pickup, previous owners may also have changed wheels for towing, off-road use, or appearance, so the truck's present setup matters as much as the badge.
Choosing the Right Tire
What should I consider when choosing a tire for a 2004 Ford Trucks F-250 Super Duty?
Start with the exact tire size the truck uses, since the 2004 Ford Trucks F-250 Super Duty can require 235/85R16, 265/75R16, or 275/65R20. After that, compare the tire's rim-width range, maximum load capacity, and whether the truck is used more for work, towing, mixed road driving, or a more appearance-focused setup.
The available choices here are all radial BFGoodrich All-Terrain T/A KO2 tires, but the fitment details still matter. A 16-inch application and a 20-inch application call for different wheels, and even the two 16-inch sizes should not be treated as interchangeable without checking the truck's current configuration. Sidewall presentation can also influence the final choice if visual style matters.
What sidewall styles are available for 2004 Ford Trucks F-250 Super Duty tires?
Sidewall styling for the 2004 Ford Trucks F-250 Super Duty includes both RWL and RBL treatments among the available tires. The 235/85R16 and 265/75R16 BFGoodrich All-Terrain T/A KO2 options use RWL, while the 275/65R20 version uses RBL. Those details can matter for owners who want a more traditional truck look or a more subdued sidewall presentation.
Sidewall style should be chosen after the correct tire size and wheel diameter are confirmed, not before. An appearance preference does not override fitment. Once the proper size is locked in, the sidewall treatment becomes part of how the truck will present visually, especially on trims such as Harley-Davidson Edition where wheel and tire appearance can change the truck's overall character.
What brands offer tires for the 2004 Ford Trucks F-250 Super Duty?
BFGoodrich is the available brand across the supported tire sizes for the 2004 Ford Trucks F-250 Super Duty. The offered tires are from the All-Terrain T/A KO2 series in 235/85R16, 265/75R16, and 275/65R20. That keeps brand comparison simple and shifts the real decision toward choosing the correct fitment, wheel match, and specification range for the truck.
Because the product assortment is centered on one tire family, owners should pay closer attention to size-specific details such as rim-width range, load capacity, and sidewall style. A heavy-duty pickup can have very different needs depending on how it is used, so the correct approach is matching the tire to the truck's actual wheel setup and intended duty rather than shopping by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Ford Trucks F-250 Super Duty?
A period-style choice for a 2004 Ford Trucks F-250 Super Duty starts with the correct original-type fitment size for the truck's specific sub-model and wheel diameter. That means choosing among 235/85R16, 265/75R16, or 275/65R20 as appropriate, rather than selecting by appearance alone. Staying with the proper size preserves the truck's intended stance and helps avoid a mismatched look.
After the size is confirmed, sidewall treatment and wheel package become the visual details that shape the final presentation. Raised white letter styling is available on the 16-inch options, while the 20-inch fitment uses an RBL sidewall. For owners seeking a very exact restoration appearance, trim-specific historical references and original vehicle documentation are worth consulting before settling on the final look.
Does correct tire fitment matter for a 2004 Ford Trucks F-250 Super Duty restoration?
Correct tire fitment matters on a 2004 Ford Trucks F-250 Super Duty restoration because the truck uses more than one size and more than one rim diameter across the lineup. A King Ranch on 235/85R16, a Lariat on 265/75R16, and a Harley-Davidson Edition on either 16-inch or 20-inch fitment will each present differently if the wrong size is installed.
Proper fitment affects more than appearance. It also influences wheel compatibility, clearance, and how convincingly the finished truck reflects its intended trim identity. Even on a newer collector-era pickup, getting the size right is one of the quickest ways to avoid a restoration that looks slightly off, especially when the truck is viewed alongside correctly equipped examples.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Ford Trucks F-250 Super Duty?
Yes, modifications can affect tire fitment on a 2004 Ford Trucks F-250 Super Duty. Aftermarket wheels, suspension lifts, leveling kits, lowering changes, and body alterations can all change how a 235/85R16, 265/75R16, or 275/65R20 tire sits on the truck. Even when the nominal tire size is correct, wheel width and the truck's altered geometry can change the real fitment picture.
A modified truck should be checked for wheel diameter, wheel width, steering clearance, and any contact points at full turn or suspension movement. It also helps to confirm that the replacement tire's load capacity matches how the truck is actually used. On a Super Duty, changes made for appearance can still carry work-truck consequences if the fitment is not reviewed carefully.
What should I inspect before driving a 2004 Ford Trucks F-250 Super Duty on new tires?
Before driving a 2004 Ford Trucks F-250 Super Duty on new tires, inspect the wheel diameter and width, confirm the tire size matches the truck's setup, and verify inflation is appropriate for the tire being used. It is also smart to look over lug torque, valve stems, tread seating, and any visible signs of rubbing near the suspension, inner fenders, or steering components.
A short initial road check can reveal vibration, pull, or contact that is not obvious while the truck is parked. Rechecking pressure after the first drives is worthwhile, especially on a heavy-duty pickup that may carry tools, trailers, or varying loads. Catching an issue early is easier than discovering clearance or pressure problems on a longer trip.
How often should tires on a 2004 Ford Trucks F-250 Super Duty be inspected?
Tires on a 2004 Ford Trucks F-250 Super Duty should be inspected regularly, with a close look before longer trips, towing, or heavier work use. Check tread wear, air pressure, cuts, punctures, bulges, and sidewall damage, and pay attention to any uneven wear pattern that might point to alignment, suspension, or inflation issues.
A Super Duty that sits for stretches still needs routine inspection, since age, weather exposure, and slow air loss can affect tire condition even when mileage stays low. Trucks with mixed use deserve extra attention because jobsite debris and load changes add stress. Frequent visual checks and pressure checks are simple habits that help keep the fitment safe and the truck predictable on the road.
