The 1989 Ford Trucks F-250 sits in the final years of the classic brick-nose Ford pickup era, a time when three-quarter-ton trucks were expected to handle real work while still serving as everyday transportation. That matters when choosing tires, because this F-250 uses 16-inch radial fitments and can take 215/85R16, 235/85R16, or 7.50R16 depending on the specific sub-model and GVWR. The key decision is less about vintage bias-ply versus radial construction and more about confirming the exact truck configuration, tire sizing format, and intended use. Owners balancing original-style proportions, load-carrying needs, and wheel compatibility should verify the truck's exact setup before settling on a tire.
Which Tire Size Is Right for The 1989 Ford Trucks F-250
Three primary tire sizes apply to the 1989 Ford Trucks F-250, and the right one depends on the truck's exact sub-model and GVWR rather than on wheel diameter alone. All three are radial 16-inch fitments, so the first step is identifying whether the truck is a 6600 GVWR model, a 7700 GVWR model, or an H.D. version before comparing tire style, sizing format, and available product choices.
215/85R16 is a metric radial size in which 215 represents the section width in millimeters, 85 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 1989 Ford Trucks F-250, it serves as one of the 16-inch radial fitments used on certain 6600 GVWR sub-models. Its proportions place it in the narrower end of the truck's available tire choices for this page. This size is worth considering when the truck's original-style configuration calls for it and the wheel setup matches the intended metric radial fitment.
235/85R16 is a metric radial size, with 235 indicating section width in millimeters, 85 representing the aspect ratio, R for radial construction, and 16 for the rim diameter. This is the broadest-reaching fitment on the 1989 Ford Trucks F-250, appearing across 6600 GVWR, 7700 GVWR, and H.D. sub-models. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter styling and a 6.0 to 7.5 inch rim-width range. It is the size to verify first on heavier-duty or higher-GVWR F-250 configurations.
7.50R16 uses an older numeric radial convention, with 7.50 indicating nominal section width, R identifying radial construction, and 16 showing the wheel diameter in inches. On the 1989 Ford Trucks F-250, this size appears on certain 6600 GVWR sub-models and presents a more traditional truck-tire format than the metric alternatives. It can appeal to owners trying to stay closer to an older heavy-duty pickup tire look while remaining within a radial construction family. As with the other sizes, the truck's exact sub-model and wheel setup should be confirmed before selection.
Sub-model fitment matters on the 1989 Ford Trucks F-250 because tire size changes with GVWR and H.D. designation. Some versions can use more than one 16-inch radial size, while others narrow the choice to 235/85R16, so identifying the exact truck configuration is the first step.

1989 Ford Trucks F-250 Custom (GVWR 6600)
The 1989 Ford Trucks F-250 Custom (GVWR 6600) can use 215/85R16, 235/85R16, or 7.50R16, all in radial construction on 16-inch wheels. That makes this one of the more configuration-sensitive versions, so the actual wheel and tire setup on the truck should be checked before choosing between metric and older numeric sizing formats.
The 1989 Ford Trucks F-250 Custom (GVWR 7700) uses 235/85R16, which simplifies tire selection compared with the lower-GVWR version. The focus here shifts from deciding among multiple primary sizes to choosing the right tire style, rim-width compatibility, and intended road or work use within that size.
The 1989 Ford Trucks F-250 Custom H.D. uses 235/85R16 radial tires on 16-inch wheels. Since the size itself is straightforward, the next decision is comparing available tires in that fitment and confirming that the truck still carries the wheel width and overall setup appropriate to that heavier-duty configuration.
The 1989 Ford Trucks F-250 XL (GVWR 6600) shares the same three-size range as other 6600 GVWR trucks: 215/85R16, 235/85R16, and 7.50R16. Selection depends on which size is actually on the truck now, whether the owner wants a metric radial or an older-style numeric radial presentation, and whether the wheels match that choice.
The 1989 Ford Trucks F-250 XL (GVWR 7700) uses 235/85R16, keeping fitment simple at the size level. With only one primary size to confirm, the buyer can focus more closely on tire character, sidewall style, and wheel-width suitability for the truck's intended use.
The 1989 Ford Trucks F-250 XL H.D. uses the 235/85R16 radial size. That points the decision toward selecting the right product within that fitment and making sure the truck's wheels, load expectations, and any later modifications still suit a tall 16-inch heavy-duty pickup tire.
The 1989 Ford Trucks F-250 XLT Lariat (GVWR 6600) can be fitted with 215/85R16, 235/85R16, or 7.50R16, all as 16-inch radial options. Because more than one primary size applies, this is a truck where the exact existing wheel and tire combination deserves a close check before replacement.
The 1989 Ford Trucks F-250 XLT Lariat (GVWR 7700) uses 235/85R16 radial tires. That makes size confirmation straightforward, leaving the buyer to compare product traits such as sidewall treatment, series, and wheel-width compatibility rather than sorting through multiple primary fitments.
The 1989 Ford Trucks F-250 XLT Lariat H.D. uses 235/85R16 on a 16-inch wheel. Owners of this version should concentrate on choosing a tire that matches the truck's working role and current wheel setup, especially if aftermarket wheels or suspension changes may have altered the original fitment environment.
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.

Tire Size & Fitment
What tire size fits a 1989 Ford Trucks F-250?
A 1989 Ford Trucks F-250 can use 215/85R16, 235/85R16, or 7.50R16, depending on the exact sub-model. All three are radial 16-inch fitments, but they do not apply uniformly across the full F-250 lineup. The 6600 GVWR versions have the widest range of size possibilities, while 7700 GVWR and H.D. versions use 235/85R16.
The practical step is identifying the truck's exact designation before replacing tires. A Custom, XL, or XLT Lariat badge alone is not enough, because GVWR and H.D. status affect which size belongs on the truck. Checking the existing wheel and tire setup is especially important on older pickups that may have been changed over time.
What size rim does a 1989 Ford Trucks F-250 use?
The tire fitments covered for the 1989 Ford Trucks F-250 use a 16-inch rim diameter. That is consistent across 215/85R16, 235/85R16, and 7.50R16, even though the sizing formats differ. The key point is that all of the primary tire choices on this page are built around the same wheel diameter.
Rim diameter is only part of the fitment picture, so the wheel should still be checked before mounting new tires. Width matters as well, especially when moving among different radial sizes or comparing a product with a stated rim-width range. An older F-250 may also have aftermarket wheels, which makes a visual confirmation worthwhile.
Why does the 1989 Ford Trucks F-250 have more than one tire size?
The 1989 Ford Trucks F-250 has more than one tire size because the lineup includes different sub-models and weight ratings. Trucks in the 6600 GVWR group can use 215/85R16, 235/85R16, or 7.50R16, while the 7700 GVWR and H.D. versions narrow down to 235/85R16. The variation reflects configuration differences within the same model family.
That means tire selection starts with the exact truck, not just the model name. A replacement chosen for one F-250 may not be the right starting point for another with a different GVWR or duty rating. The safest approach is to confirm the sub-model and inspect the current wheel-and-tire combination before comparing products.
Choosing the Right Tire
What should I consider when choosing a 235/85R16 tire for a 1989 Ford Trucks F-250?
Start with the fact that 235/85R16 is the shared fitment across the broadest range of 1989 Ford Trucks F-250 sub-models, including 7700 GVWR and H.D. versions. From there, compare construction, sidewall style, intended use, and wheel compatibility. In the available product range for this page, that includes a radial BFGoodrich All-Terrain T/A KO2.
The truck's job should guide the final choice. A road-driven pickup may prioritize a different look than a truck kept for utility or mixed-surface use, and the wheel should match the tire's specified rim-width range. It also helps to confirm whether the F-250 still has its original wheel setup or has been changed over the years.
What sidewall styles are available for 1989 Ford Trucks F-250 tires?
Sidewall styling visible in the available 1989 Ford Trucks F-250 product selection includes RWL, or raised white letter, in 235/85R16. That gives buyers a more expressive truck-tire appearance than a plain black sidewall presentation. Sidewall style does not change the tire's basic size fitment, but it does affect how the truck looks once mounted.
Appearance matters differently depending on the truck's role. A work-focused F-250, a preserved original-style pickup, and a lightly restored weekend truck may call for different visual choices even when the size is the same. It helps to decide early whether the goal is a more traditional look or a more aggressive period truck appearance.
What brands offer tires for the 1989 Ford Trucks F-250?
BFGoodrich is represented in the available 1989 Ford Trucks F-250 product selection, specifically in 235/85R16. The tire series shown is the All-Terrain T/A KO2, which places the emphasis on a modern radial truck tire offering within one of the F-250's primary fitments. Brand choice here is tied closely to the exact size being considered.
That means the first decision is still fitment, not brand name alone. Once the correct size is confirmed for the truck's sub-model, the product comparison becomes more meaningful because wheel-width range, sidewall presentation, and intended use can be judged in context. A well-matched tire matters more than choosing by brand without verifying size.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Ford Trucks F-250?
A period-style starting point for a 1989 Ford Trucks F-250 is the primary size that matches the truck's exact sub-model, whether that is 215/85R16, 235/85R16, or 7.50R16. Among those, 7.50R16 carries an older numeric presentation that can appeal to owners seeking a more traditional heavy-duty pickup look while staying in radial construction.
Appearance should still be balanced against the truck's real setup and intended use. A preserved work truck, a clean original-style survivor, and a more updated road truck may not call for the same visual approach. When exact originality matters, vehicle-specific literature and marque expertise are the best references beyond the basic fitment itself.
Does correct tire fitment matter for a 1989 Ford Trucks F-250 restoration?
Correct tire fitment matters on a 1989 Ford Trucks F-250 restoration because the truck can use more than one primary size depending on GVWR and H.D. status. Getting the sub-model right keeps the wheel diameter, tire proportions, and overall stance closer to the way that particular configuration was intended to sit and work.
Fitment also affects the finished truck visually. A tire that is right for a 7700 GVWR or H.D. F-250 may not create the same appearance on a 6600 GVWR version that could also use 215/85R16 or 7.50R16. Even on a restoration-focused project, the current wheels and any earlier modifications should be checked before final tire selection.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Ford Trucks F-250?
Yes, modifications can affect tire fitment on a 1989 Ford Trucks F-250 even when the tire size itself is correct for the model line. Aftermarket wheels, different wheel widths, suspension lifts or lowering changes, and body or steering alterations can all change how a 16-inch tire sits and clears. That matters with any of the truck's primary sizes.
A modified F-250 should be checked at the wheel opening and through steering travel before settling on replacement tires. Clearance around leaf springs, fenders, and suspension components deserves attention, especially on an older truck that may have been changed more than once. Actual wheel dimensions are just as important as the size printed on the sidewall.
What should I inspect before driving a 1989 Ford Trucks F-250 on new tires?
Before driving a 1989 Ford Trucks F-250 on new tires, inspect the wheels, valve stems, lug hardware, and the general condition of the suspension and steering components. The tires themselves should be checked for proper inflation, secure bead seating, and any obvious interference once mounted. A short, careful first drive helps confirm that the setup is behaving normally.
An older three-quarter-ton truck also benefits from a second look after the first miles. Recheck pressure, look for any scuffing that suggests clearance trouble, and pay attention to vibration or pulling that could point to a wheel or alignment issue. Those simple checks are especially worthwhile when replacing aged tires on a truck that has seen limited recent use.
How should tires on a collector 1989 Ford Trucks F-250 be maintained?
Tires on a collector 1989 Ford Trucks F-250 should be maintained with regular pressure checks, visual inspections, and sensible storage habits. Even a truck that sees only occasional use can develop sidewall cracking, flat spotting, or air loss if it sits for long periods. Tread depth alone is not enough to judge the condition of an older tire on a low-mileage vehicle.
Storage environment matters almost as much as mileage. Keeping the truck away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition over time. It is also smart to inspect the tires before every longer drive, especially on a heavier pickup where wheel, suspension, and load-related stresses are greater than on a lighter collector vehicle.
