The 1991 Dodge Trucks D250 sits in the era when heavy-duty pickups were expected to work hard yet still cover long highway miles with confidence. For owners restoring, maintaining, or still using one as a real-duty truck, tire fitment matters as much as appearance because the D250 bridges classic truck character with modern road use expectations. This model uses radial tire fitments in 215/85R16 and 235/85R16 on 16-inch rims, with the exact size depending on configuration. That makes the key choice less about vintage bias-ply versus radial and more about confirming the right size, load-carrying capability, and overall stance for the truck you have.
Which Tire Size Is Right for The 1991 Dodge Trucks D250
The 1991 Dodge Trucks D250 uses two primary tire sizes, and both are radial tires built for 16-inch rims. The most important first step is confirming the exact sub-model, since the Base can use either 215/85R16 or 235/85R16 while the Heavy Duty (GVWR 8510) uses 235/85R16. Once size is confirmed, the real decision shifts to tire specifications, load suitability, and the overall look and use of the truck.
A 215/85R16 uses a 215-millimeter section width, an 85-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 1991 Dodge Trucks D250, this is a modern metric radial fitment that suits trucks using the narrower of the two primary sizes. Its tall, work-oriented sizing reflects the practical character of the D250 platform rather than a low-profile or appearance-driven setup. This size should be chosen only after confirming the truck is one of the D250 configurations that actually uses 215/85R16.
A 235/85R16 has a 235-millimeter section width, an 85-series profile, radial construction, and it mounts on a 16-inch wheel. On the 1991 Dodge Trucks D250, this size applies to the Heavy Duty (GVWR 8510) and can also appear on the Base model, making it the more broadly shared fitment. Available product selection in this size includes a BFGoodrich All Terrain T/A KO2 with raised white letter sidewalls and a 6.0 to 7.5-inch rim-width range. It is the size to evaluate when the truck needs heavier-duty visual presence and the wheel setup matches the tire's intended range.
Sub-model fitment matters on the 1991 Dodge Trucks D250 because tire size is not identical across every configuration. The Base has more than one acceptable size, while the Heavy Duty (GVWR 8510) narrows the decision to one primary fitment, so identifying the truck correctly should come before comparing tires.

1991 Dodge Trucks D250 Base
The 1991 Dodge Trucks D250 Base can use either 215/85R16 or 235/85R16, both in radial construction on 16-inch rims. That means tire selection starts with confirming which wheel and tire setup is already on the truck before comparing brand, sidewall style, or load-related specifications.
The 1991 Dodge Trucks D250 Heavy Duty (GVWR 8510) uses 235/85R16 radial tires. For this sub-model, the main questions are not which primary size fits, but whether the wheel width, tire specification, and intended truck use all line up with that heavier-duty fitment.
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 1991 Dodge Trucks D250?
The 1991 Dodge Trucks D250 uses two primary tire sizes: 215/85R16 and 235/85R16. Both are radial fitments for 16-inch wheels. The Base model can use either size, while the 1991 Dodge Trucks D250 Heavy Duty (GVWR 8510) uses 235/85R16.
That makes the first step identifying the exact sub-model and confirming what is already on the truck. If the D250 has changed wheels, suspension work, or a long history of service replacements, check the wheel diameter and current tire sizing before choosing between the two primary fitments.
What size rim does a 1991 Dodge Trucks D250 use?
The 1991 Dodge Trucks D250 uses 16-inch rims with both of its primary tire sizes, 215/85R16 and 235/85R16. The shared 16-inch wheel diameter simplifies the basic fitment question, since both sizes are built around the same rim diameter.
Wheel diameter is only part of the picture, though. Width still matters, especially if the truck has replacement wheels or a heavier-duty setup. One available 235/85R16 product is intended for a 6.0 to 7.5-inch rim-width range, so checking actual wheel width is a smart step before final tire selection.
Do all 1991 Dodge Trucks D250 sub-models use the same tire size?
No. Tire size varies within the 1991 Dodge Trucks D250 line. The Base model can use either 215/85R16 or 235/85R16, while the Heavy Duty (GVWR 8510) uses 235/85R16.
That difference matters because two trucks that both say D250 on the fender may not need the same tire. Matching the tire to the exact sub-model helps avoid confusion over width, stance, and wheel compatibility, especially if the truck has been updated over the years with non-original wheels or mixed replacement tires.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Dodge Trucks D250?
Start with the correct primary size for the truck: 215/85R16 or 235/85R16. The next points to compare are radial construction details, wheel compatibility, load-related specifications, and whether the truck is being used mainly for restoration-minded upkeep, regular road driving, or heavier utility work.
A D250 that still works for hauling may call for different priorities than one kept mostly for shows or occasional cruising. Once the proper size is confirmed, compare sidewall presentation, tread character, and rim-width suitability so the tire matches both the truck's setup and the way it is actually used.
What sidewall styles are available for 1991 Dodge Trucks D250 tires?
Available sidewall styling for the 1991 Dodge Trucks D250 includes RWL, or raised white letter, in 235/85R16. That gives this truck a more assertive late-classic pickup appearance than a plain blackwall, while still staying within a correct size family for the vehicle.
Sidewall style should be chosen with the truck's overall presentation in mind. A raised white letter tire often suits owners who want a more rugged or period-flavored truck look, but appearance should come after confirming the correct size, wheel width, and load-related requirements for the D250 itself.
What brands offer tires for the 1991 Dodge Trucks D250?
BFGoodrich is available for the 1991 Dodge Trucks D250 in 235/85R16 through the All Terrain T/A KO2 line. That gives D250 owners a recognizable truck-oriented radial option within one of the vehicle's primary tire sizes.
Brand is only one part of the decision. The better approach is to confirm the correct size first, then compare the tire's series, sidewall treatment, rim-width compatibility, and load specification against the way the truck will be driven. That keeps selection focused on fitment and use rather than the brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Dodge Trucks D250?
A period-style 1991 Dodge Trucks D250 starts with the correct primary size for the truck's exact configuration: either 215/85R16 or 235/85R16. Since this model uses radial fitments, the visual decision usually comes down to choosing a tread and sidewall presentation that suits a working-class early-1990s Dodge pickup.
Owners aiming for a more traditional truck look should consider how the tire fills the wheel opening and whether a more rugged sidewall treatment supports the vehicle's overall presentation. Exact originality questions go beyond size alone, so truck-specific photos, brochures, and marque references remain useful when appearance matters as much as fitment.
How does tire construction affect the appearance of a restored 1991 Dodge Trucks D250?
On a 1991 Dodge Trucks D250, tire construction does not create a bias-ply versus radial appearance decision because the primary fitments are radial. Appearance is shaped more by the chosen size, tread character, and sidewall style than by switching between different construction eras.
That makes size accuracy especially important on a restored truck. A tire that is too narrow, too wide, or visually out of step with the D250's heavy-duty stance can change the whole look of the vehicle. Sidewall details such as raised white letters can also push the presentation toward a more truck-focused period feel.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Dodge Trucks D250?
Yes. Modifications can affect tire fitment on a 1991 Dodge Trucks D250 even when the tire size itself is one of the correct primary options. Aftermarket wheels, changes in wheel width, suspension alterations, or body and steering clearance differences can all influence how a 215/85R16 or 235/85R16 actually sits on the truck.
A D250 that has been lifted, lowered, or fitted with non-stock wheels deserves a careful check before new tires are installed. Confirm actual rim diameter and width, then inspect clearance at full steering lock and under load so the chosen tire works with the truck's present setup rather than its original specification alone.
What should I inspect before driving a 1991 Dodge Trucks D250 on new tires?
Before road use, inspect wheel condition, valve stems, lug hardware, inflation pressure, and basic clearance around the tires. It is also wise to confirm that all four tires match the intended size for the truck and that there is no rubbing against suspension, steering, or body components.
Older heavy-duty pickups often have years of repairs and parts changes behind them, so a quick visual check is not always enough. Looking for uneven ride height, worn steering parts, cracks, bulges, cuts, or signs of past contact helps catch problems early and gives the new tires a better chance to wear evenly.
How should tires on a collector 1991 Dodge Trucks D250 be maintained?
Tires on a collector 1991 Dodge Trucks D250 should be kept properly inflated, inspected regularly, and protected from long periods of heat, sunlight, moisture, and ozone exposure. Even low-mile trucks need routine checks because age and storage conditions can matter as much as tread wear on a vehicle that is not driven often.
It helps to examine the sidewalls and tread for cracking, flat spotting, air loss, or impact damage before each driving season and before any longer trip. Moving the truck occasionally, storing it on a clean surface, and checking the spare if one is carried are simple habits that support safer vintage-truck use.
