The 1985 Ford Trucks F-350 sits in the era when heavy-duty pickups were expected to work hard, tow confidently, and still serve as dependable farm, jobsite, or highway trucks. That makes tire selection more than a cosmetic decision, especially on a one-ton platform that may have seen wheel, suspension, or axle-use changes over the years. This F-350 uses three primary 16-inch tire sizes: 235/85R16 radial, 215/85R16 radial, and 750-16 bias-ply, depending on configuration. That gives owners a very different choice between modern radial truck fitment and vintage-style bias-ply options, including blackwall, wide whitewall, and more utility-focused truck patterns. The right pick starts with the exact sub-model and ends with how the truck will actually be used.
Which Tire Size Is Right for The 1985 Ford Trucks F-350
Three primary tire sizes apply to the 1985 Ford Trucks F-350, and the right one depends on the exact sub-model. All of them use a 16-inch rim, but fitment varies between radial and bias-ply construction, with single-rear-wheel and dual-rear-wheel configurations following different paths. Before choosing a tire, confirm whether the truck is a Base, XL, or XLT Lariat model and whether it is a DRW version.
215/85R16 is a metric radial size where 215 is the nominal section width in millimeters, 85 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On the 1985 Ford Trucks F-350, this size is used on DRW configurations, making it part of a work-oriented heavy-duty fitment story rather than a general fitment for every truck. Its modern radial format suits owners looking for a contemporary truck tire layout on the correct rim diameter. This size should be selected only after confirming the truck is one of the dual-rear-wheel versions that uses it.
750-16 is a numeric bias-ply size in which the 7.50 figure represents the nominal section width in inches with the decimal omitted, while 16 identifies the wheel diameter. On the 1985 Ford Trucks F-350, it appears on DRW versions as a vintage-style bias-ply fitment that suits restoration-minded owners or trucks keeping an older commercial presentation. Available choices include Firestone, Lester, BFGoodrich, and STA, with blackwall and wide whitewall styles as well as several truck and military-style series. It is the size to evaluate when traditional construction and period-style heavy-duty appearance matter as much as basic fitment.
235/85R16 is a metric radial size that uses a 235-millimeter nominal section width, an 85-series profile, radial construction, and a 16-inch rim. On the 1985 Ford Trucks F-350, this is the primary fitment for Base, XL, and XLT Lariat models that are not DRW versions. The available product assortment centers on a modern truck-oriented radial with raised white letter sidewall styling in the BFGoodrich All-Terrain T/A KO2 line. This size is the one to focus on when the truck uses the standard non-DRW radial fitment and the goal is current road use on the proper wheel setup.
Sub-model fitment on the 1985 Ford Trucks F-350 is not one-size-fits-all. Non-DRW trucks use one radial size, while DRW versions can follow either a radial or bias-ply fitment path, so confirming the exact configuration matters before choosing a tire.

1985 Ford Trucks F-350 (DRW)
The 1985 Ford Trucks F-350 (DRW) uses either 215/85R16 radial or 750-16 bias-ply tires on 16-inch rims. That gives this dual-rear-wheel configuration a clear construction choice between a modern radial truck setup and a more traditional bias-ply presentation.
The 1985 Ford Trucks F-350 Base uses 235/85R16 radial tires. Tire selection here is more straightforward, with the main job being confirmation of the existing wheel setup and choosing the product style that matches the truck's intended road use.
The 1985 Ford Trucks F-350 XL also uses 235/85R16 radial tires. For this sub-model, the decision is less about size variation and more about selecting a radial product that suits the truck's appearance, load needs, and actual driving conditions.
The 1985 Ford Trucks F-350 XL (DRW) uses either 215/85R16 radial or 750-16 bias-ply tires. That means owners should confirm whether the truck is staying with a traditional bias-ply-style setup or moving forward with a radial-based DRW fitment.
The 1985 Ford Trucks F-350 XLT Lariat uses 235/85R16 radial tires. Choosing for this sub-model comes down to keeping the correct radial size while checking wheel width, tire style, and overall suitability for how the truck is driven.
The 1985 Ford Trucks F-350 XLT Lariat (DRW) uses either 215/85R16 radial or 750-16 bias-ply tires on 16-inch wheels. That makes configuration verification especially important, since construction type and tire character can change significantly within the same sub-model family.
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 1985 Ford Trucks F-350 Tires for Sale

The product mix includes Firestone, Lester, BFGoodrich, and STA, with blackwall, wide whitewall, and raised white letter styling across classic bias-ply truck series and a modern all-terrain radial.
Common questions for the 1985 Ford Trucks F-350 usually come down to the exact tire size by sub-model, 16-inch rim fitment, bias-ply versus radial construction, and how to choose a tire that matches restoration goals, truck use, and current wheel setup.
Tire Size & Fitment
What tire size fits a 1985 Ford Trucks F-350?
A 1985 Ford Trucks F-350 can use 235/85R16, 215/85R16, or 750-16, depending on the exact configuration. Base, XL, and XLT Lariat models use 235/85R16 radial tires, while DRW versions use either 215/85R16 radial or 750-16 bias-ply tires. All of these fitments use a 16-inch rim.
The key step is confirming whether the truck is a dual-rear-wheel model before selecting a tire. Once that is settled, compare the actual wheel width, present tire construction, and overall truck setup so the chosen size matches the vehicle as it sits today rather than how it may have left the factory decades ago.
What size rim does a 1985 Ford Trucks F-350 use?
The 1985 Ford Trucks F-350 uses a 16-inch rim across its covered tire fitments. That applies to 235/85R16 radial, 215/85R16 radial, and 750-16 bias-ply sizes. Even though the tire constructions and widths vary, the common wheel diameter across these fitments is 16 inches.
Rim diameter is only the first part of the check on an older heavy-duty truck. Wheel width still matters, especially when comparing a modern radial truck tire with a vintage-style bias-ply size, so it is worth confirming the actual wheels on the truck before choosing by size code alone.
Why does the 1985 Ford Trucks F-350 have more than one tire size?
The 1985 Ford Trucks F-350 has more than one tire size because fitment changes by sub-model and rear-wheel configuration. Non-DRW trucks use 235/85R16 radial tires, while DRW versions use either 215/85R16 radial or 750-16 bias-ply tires. The variation reflects different tire constructions and truck setups within the same model line.
That makes configuration verification more important than simply matching the model name on the fender. An F-350 that has had wheel changes, axle swaps, or long-term service modifications may no longer be wearing the same setup it was built around, so the tire choice should follow the actual truck and wheel hardware in front of you.
Bias-Ply & Radial Options
Is 750-16 a bias-ply or radial tire for the 1985 Ford Trucks F-350?
On the 1985 Ford Trucks F-350, 750-16 is a bias-ply tire size. It appears on DRW configurations and uses the older numeric sizing format common to vintage truck tires, where the 7.50 figure refers to nominal section width and the 16 refers to wheel diameter.
That matters because a bias-ply truck tire gives the vehicle a different appearance and construction character than a modern metric radial. Buyers considering 750-16 should also compare the intended use of the truck, the wheel width, and whether the goal is a traditional heavy-duty look or a more current radial-style driving setup.
Should I use bias-ply or radial tires on a 1985 Ford Trucks F-350?
A 1985 Ford Trucks F-350 can fall on either side of that decision depending on configuration. Non-DRW trucks use a radial 235/85R16 fitment, while DRW trucks can use either 215/85R16 radial or 750-16 bias-ply. The right direction depends on the truck's exact setup and whether the goal is modern radial use or traditional bias-ply presentation.
Construction choice affects more than appearance on a heavy-duty pickup. Wheel dimensions, current suspension condition, intended load use, and clearance should all be reviewed before changing from one construction type to another, especially on a truck that may have spent years in commercial service or been modified along the way.
What should I check before converting my 1985 Ford Trucks F-350 from bias-ply to radial tires?
Start by confirming that the truck's actual fitment supports a radial size used on the 1985 Ford Trucks F-350, such as 215/85R16 or 235/85R16, rather than assuming any 16-inch tire is an acceptable change from 750-16. Conversion should begin with the exact sub-model, wheel setup, and whether the truck is a DRW configuration.
Practical checks should include wheel width, overall tire clearance, rear dual spacing where applicable, and the condition of steering and suspension components. A one-ton truck can be sensitive to setup differences, so the safest approach is to treat the change as a full fitment review rather than simply a switch in construction type.
Choosing the Right Tire
What should I consider when choosing a tire for a 1985 Ford Trucks F-350?
Begin with the exact fitment path for the truck. A 1985 Ford Trucks F-350 may use 235/85R16 radial, 215/85R16 radial, or 750-16 bias-ply, so the first decision is always the correct sub-model and whether the truck is DRW. After that, construction type, intended use, and wheel compatibility become the real selection factors.
Once the size is confirmed, compare the tire's style and purpose against how the truck is used today. A restoration-oriented build may lean toward bias-ply appearance, while a truck seeing regular road duty may call for a modern radial format, provided the wheels and overall setup support that choice.
What sidewall styles are available for 1985 Ford Trucks F-350 tires?
Sidewall choices for the 1985 Ford Trucks F-350 include blackwall, wide whitewall, and raised white letter styling, depending on the tire size and product line. The broadest sidewall variety appears in 750-16 bias-ply tires, while the 235/85R16 radial option shown here uses a raised white letter presentation.
That means sidewall style should be chosen as part of the truck's overall character, not as a stand-alone detail. A work-truck look, a more restoration-minded appearance, or a later all-terrain presentation can each point in a different direction even when the wheel diameter remains the same.
What brands offer tires for the 1985 Ford Trucks F-350?
Available tire brands for the 1985 Ford Trucks F-350 include Firestone, Lester, BFGoodrich, and STA. Most of that variety appears in the 750-16 bias-ply category, where classic passenger-style and truck-oriented patterns are both present, while the 235/85R16 radial fitment is represented by BFGoodrich.
Brand choice should come after the truck's correct tire size and construction have been confirmed. Once those are established, compare what each brand offers in terms of tire series, sidewall treatment, rim-width compatibility, and the overall look or duty character you want the finished truck to carry.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Ford Trucks F-350?
For a period-style 1985 Ford Trucks F-350, the starting point is the truck's correct primary size and construction for its configuration. DRW models can be especially relevant here because 750-16 bias-ply is part of the fitment picture, giving owners access to traditional-looking blackwall and wide whitewall options in classic truck-oriented series.
A restoration-minded choice should balance size accuracy, construction type, and visual character rather than focusing on brand alone. When exact originality matters beyond general period style, checking marque-specific reference material, surviving truck documentation, or knowledgeable Ford truck sources is the best way to refine the final appearance decision.
How does tire construction affect the appearance of a restored 1985 Ford Trucks F-350?
Tire construction changes the look of a restored 1985 Ford Trucks F-350 in a noticeable way. A 750-16 bias-ply tire gives the truck a more traditional vintage presentation, while 215/85R16 and 235/85R16 radials create a more modern visual impression tied to later truck use and contemporary road-going setups.
That difference is especially important when the truck's stance and character are part of the restoration goal. Owners aiming for a working-era appearance often start with the proper construction type first, then narrow the choice by sidewall treatment and tread style so the finished truck looks cohesive from wheel to body.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Ford Trucks F-350?
Yes, modifications can affect tire fitment on a 1985 Ford Trucks F-350 even when the truck still uses a 16-inch wheel. Changes such as aftermarket wheels, different wheel widths, altered rear dual spacing, suspension lifts, lowering, or replacement axles can all change how a 235/85R16, 215/85R16, or 750-16 tire sits on the vehicle.
That is why a modified truck should be measured, not assumed. Wheel width, tire-to-fender clearance, steering travel, and spacing between rear tires on DRW models should all be verified before a new tire is selected, especially when moving between a vintage bias-ply setup and a modern radial truck fitment.
What should I inspect before driving a 1985 Ford Trucks F-350 on new tires?
Before driving a 1985 Ford Trucks F-350 on new tires, inspect the wheels for the correct diameter and sound condition, then check valve stems, lug hardware, and the general condition of the suspension and steering. On the tires themselves, confirm proper inflation, look for any shipping or mounting damage, and make sure the selected size matches the truck's actual configuration.
A heavy-duty pickup benefits from a slow, deliberate first road test. Listen for rubbing, feel for pulling or vibration, and recheck clearances after the truck has rolled and settled, particularly if it is a DRW model or has spent years with older wheels, worn springs, or other age-related setup changes.
How should tires on a collector-era 1985 Ford Trucks F-350 be maintained?
Tires on a collector-era 1985 Ford Trucks F-350 should be maintained with regular pressure checks, visual inspections, and attention to age-related condition even if the truck sees limited mileage. Sidewall cracking, flat spotting, cuts, bulges, and slow air loss matter just as much on a low-use truck as tread wear does on a daily driver.
Storage conditions also play a major role in tire life. Keeping the truck away from prolonged heat, direct sunlight, standing moisture, and ozone sources helps preserve both bias-ply and radial tires, while occasional movement and routine inspection make it easier to catch developing problems before the next road trip or show season.
