The 2004 Ford Trucks Explorer Sport Trac sits in an interesting space between SUV utility and midsize pickup practicality, giving owners a truck bed without leaving behind the familiar Explorer-based driving character. That mix makes tire choice more than a routine replacement decision, especially when trim level affects fitment. This model uses 16-inch radial tires, with either 235/70R16 or 255/70R16 depending on the sub-model. Available choices range from raised white letter all-terrain styling to wide whitewall radials with a more distinctive custom or retro presentation. The right selection starts with confirming the exact trim and then matching the tire's look, load capacity, and intended road use.
Which Tire Size Is Right for The 2004 Ford Trucks Explorer Sport Trac
Two primary tire sizes apply to the 2004 Ford Trucks Explorer Sport Trac, and both are radial tires built for 16-inch wheels. The correct choice depends first on the exact sub-model, since some trims use 235/70R16, others use 255/70R16, and the XLT appears with either size. Before choosing a tire, confirm the trim and verify the actual wheel setup if the truck has been changed from stock-style wheels.
255/70R16 is a metric radial size in which 255 identifies the nominal section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 16 is the wheel diameter in inches. On the 2004 Ford Trucks Explorer Sport Trac, this size is used on certain trims and keeps the tire decision centered on a modern radial setup. Available choices here focus on BFGoodrich's All Terrain T/A KO2 with raised white letter styling. This size is worth considering when your specific trim calls for it and you want to confirm wheel width, load needs, and overall intended use.
235/70R16 is a metric radial size with a 235-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 2004 Ford Trucks Explorer Sport Trac, it appears on specific trims and offers a wider spread of visual and product choices than the larger size. Options include BFGoodrich raised white letter all-terrain styling as well as wide whitewall radials from American Classic and Coker Classic. This size deserves a closer look when appearance matters as much as fitment, especially on an XLT or XLS where style and use can point in different directions.
2004 Ford Trucks Explorer Sport Trac Sub-Model Tires
Tire fitment varies by sub-model on the 2004 Ford Trucks Explorer Sport Trac, so trim identification matters before choosing a replacement. The main distinction is between 235/70R16 and 255/70R16, with the XLT appearing in either size depending on the truck's setup.

2004 Ford Trucks Explorer Sport Trac Adrenalin
The 2004 Ford Trucks Explorer Sport Trac Adrenalin uses the 255/70R16 radial size on a 16-inch wheel. Tire selection here is less about choosing between sizes and more about confirming the wheel width and deciding whether an all-terrain, raised white letter presentation matches how the truck is used.
The 2004 Ford Trucks Explorer Sport Trac XLS uses the 235/70R16 radial size. That opens the door to either a more utility-oriented raised white letter tire or a wide whitewall radial, so the decision often comes down to whether the truck is being kept practical, customized, or styled with a more retro look.
The 2004 Ford Trucks Explorer Sport Trac XLT appears with either 235/70R16 or 255/70R16 radial tires, making wheel and trim verification especially important. Before comparing brands or sidewall styles, check the actual tire placard, wheel width, and the size already fitted to the truck if it has remained close to its original setup.
The 2004 Ford Trucks Explorer Sport Trac XLT Premium uses the 255/70R16 radial size. Once that size is confirmed, the main selection factors are rim-width compatibility, load capacity, and whether the truck's appearance and use favor a more aggressive all-terrain tire style.
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 Explorer Sport Trac Tires for Sale

Tire questions for the 2004 Ford Trucks Explorer Sport Trac usually come down to trim-specific sizing, 16-inch wheel fitment, sidewall style, and choosing between utility-focused and appearance-focused radial options.
Tire Size & Fitment
What tire size fits a 2004 Ford Trucks Explorer Sport Trac?
The 2004 Ford Trucks Explorer Sport Trac uses either 235/70R16 or 255/70R16, depending on the sub-model. Both are radial tire sizes for 16-inch wheels. Adrenalin and XLT Premium use 255/70R16, XLS uses 235/70R16, and XLT appears with either size.
That means the first step is identifying the exact trim and then checking the actual wheels on the truck. On an XLT especially, the safest approach is to confirm the current tire size, wheel width, and placard information before choosing a replacement, since the two sizes are not interchangeable by assumption.
What size rim does a 2004 Ford Trucks Explorer Sport Trac use?
Both primary tire sizes used on the 2004 Ford Trucks Explorer Sport Trac are built for 16-inch rims. Whether the truck uses 235/70R16 or 255/70R16, the wheel diameter remains the same, so the fitment difference is in tire width and overall sizing rather than rim diameter.
Wheel diameter is only part of the picture, though. Rim width still matters when selecting among available tires, and that becomes especially important if the truck has aftermarket wheels. A 16-inch wheel can still be unsuitable if its width does not fall within the tire's approved range.
Why does the 2004 Ford Trucks Explorer Sport Trac have more than one tire size?
More than one tire size appears on the 2004 Ford Trucks Explorer Sport Trac because fitment varies by sub-model. The XLS uses 235/70R16, the Adrenalin and XLT Premium use 255/70R16, and the XLT can be found with either size. Both sizes are radial and both fit 16-inch wheels.
That makes trim identification more important than it might seem at first glance. A buyer should confirm the exact sub-model and inspect the truck's present wheel-and-tire setup before replacement, particularly on an XLT where either size may be correct depending on how that truck was equipped.
Choosing the Right Tire
What should I consider when choosing a 2004 Ford Trucks Explorer Sport Trac tire?
Start with the correct size for the trim, since the 2004 Ford Trucks Explorer Sport Trac uses either 235/70R16 or 255/70R16. From there, compare construction details such as approved rim-width range, load capacity, sidewall style, and whether the tire is aimed at all-terrain use or a more appearance-oriented street presentation.
A practical truck that sees mixed-road duty may point toward a different choice than one kept mainly for cruising or custom styling. Matching the tire to how the Sport Trac is actually driven usually matters more than choosing by brand name alone, especially when both utility and visual style are part of the decision.
What sidewall styles are available for 2004 Ford Trucks Explorer Sport Trac tires?
Two distinct sidewall styles are available for this Explorer Sport Trac fitment. The BFGoodrich options use RWL, or raised white letter styling, while some 235/70R16 radial choices from American Classic and Coker Classic use a 2.375-inch wide whitewall for a more custom or retro appearance.
Sidewall style can change the truck's overall character even when the size remains correct. Raised white letters lean toward a sport-truck or off-road look, while a wide whitewall gives the 235/70R16 fitment a much more stylized presentation. Appearance should be weighed alongside wheel width and intended use.
What brands offer tires for the 2004 Ford Trucks Explorer Sport Trac?
BFGoodrich, American Classic, and Coker Classic all offer tires for the 2004 Ford Trucks Explorer Sport Trac within the listed fitment sizes. BFGoodrich appears in both 235/70R16 and 255/70R16, while American Classic and Coker Classic wide whitewall options are available in 235/70R16.
Brand choice here is closely tied to tire character rather than name alone. BFGoodrich covers the more utility-oriented all-terrain look, while American Classic and Coker Classic serve buyers who want a wide whitewall radial. The right comparison is size first, then sidewall style, load rating, and wheel compatibility.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Ford Trucks Explorer Sport Trac?
A period-style choice depends on which version of the 2004 Ford Trucks Explorer Sport Trac is being preserved and what visual direction fits the truck. BFGoodrich All Terrain T/A KO2 options suit a more assertive sport-truck or utility look, while 235/70R16 wide whitewall radials create a distinctly customized appearance.
Because this is a 2004 model, appearance goals can vary widely between original-looking preservation and later custom treatment. Start with the correct tire size for the trim, then choose the sidewall and series that best match the truck's stance and presentation without assuming any one option is factory-original.
How does tire construction affect the appearance of a restored 2004 Ford Trucks Explorer Sport Trac?
On the 2004 Ford Trucks Explorer Sport Trac, construction is straightforward because the primary fitments are radial tires. The visible appearance difference comes less from bias-ply versus radial and more from the tire's sidewall treatment, tread character, and overall profile within either 235/70R16 or 255/70R16.
That means a restored or carefully kept Sport Trac can take on very different visual personalities even while staying within the correct radial fitment. Raised white letters create a more rugged, performance-minded impression, while a wide whitewall shifts the truck toward a custom street presentation on the smaller listed size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Ford Trucks Explorer Sport Trac?
Yes, modifications can affect tire fitment on a 2004 Ford Trucks Explorer Sport Trac even when the tire size itself looks correct. Aftermarket wheels, changes in rim width, suspension alterations, or body modifications can all influence whether a 235/70R16 or 255/70R16 tire has the proper clearance.
A truck that has been lifted, lowered, or fitted with different wheels should be checked more carefully than one on an unaltered setup. Steering clearance, fender space, and wheel width deserve attention before replacement, especially on an XLT where more than one primary size may already be in play.
What should I inspect before driving a 2004 Ford Trucks Explorer Sport Trac on new tires?
Before road use, inspect inflation pressure, lug-nut torque, tread seating, and visible clearance at the fenders and suspension. It is also worth checking for uneven wear patterns on the old tires, since they can point to alignment or suspension issues that may affect how the new tires behave.
A closer inspection matters even more on a truck that has sat for long periods or has recently changed wheel-and-tire combinations. Looking over shocks, steering components, and brake condition helps make sure the new tires are being installed on a stable, roadworthy platform rather than masking other problems.
How often should tires on a 2004 Ford Trucks Explorer Sport Trac be inspected?
Tires on a 2004 Ford Trucks Explorer Sport Trac should be inspected regularly, not just at replacement time. Check them for air loss, irregular wear, cuts, bulges, and sidewall cracking, and make those inspections more frequent if the truck is driven seasonally, stored for long periods, or used on rougher surfaces.
Routine inspection is especially helpful on an older truck where age, storage conditions, and suspension wear can all influence tire life. Keeping pressure set correctly and catching problems early helps preserve ride quality, protect the wheels, and avoid choosing a new tire when the real issue is elsewhere on the vehicle.
