1991 Dodge Trucks D350 Tires

A 1991 Dodge Trucks D350 can use 215/85R16, 750-16, or 235/85R16, depending on the exact sub-model. The DRW version uses either 215/85R16 radial or 750-16 bias-ply, while the D350 Base uses 235/85R16 radial. All of these sizes are built around a 16-inch rim diameter.

The practical step is to identify whether the truck is a DRW model or a Base model before choosing a tire. After that, confirm the actual wheel setup on the truck, especially if it has been changed over the years, because construction type, wheel width, and intended truck use all affect which of these sizes makes sense.

The covered tire fitments for the 1991 Dodge Trucks D350 use a 16-inch rim diameter. That applies to the 215/85R16 radial, the 750-16 bias-ply, and the 235/85R16 radial sizes used across the D350 sub-models. Rim diameter is consistent even though the tire constructions and size formats are different.

That consistency simplifies one part of the search, but it does not mean every 16-inch wheel is automatically suitable for every D350 tire option. Width, dual-wheel spacing on DRW trucks, and the actual wheel already on the truck still matter, so the tire choice should be matched to the wheel as carefully as the tire size itself.

No, the 1991 Dodge Trucks D350 sub-models do not all use the same tire size. The D350 (DRW) uses 215/85R16 radial or 750-16 bias-ply, while the D350 Base uses 235/85R16 radial. That means the truck’s exact configuration changes both the size and, in some cases, the tire construction.

This matters because a D350 tire search can look correct at first glance while still pointing to the wrong setup. Owners should verify the sub-model, count the rear wheels where applicable, and inspect the wheels currently on the truck before choosing between a modern metric radial and a more traditional numeric bias-ply fitment.

On the 1991 Dodge Trucks D350, 750-16 is a bias-ply tire size. It appears on the DRW configuration and uses a traditional numeric truck-tire format rather than a modern metric radial format. That makes it different in both construction and sizing style from the 215/85R16 and 235/85R16 radial fitments.

That distinction affects both appearance and wheel setup decisions. A truck already running 750-16 bias-ply tires may be set up around that traditional construction, while a move toward radial tires calls for careful checking of wheel compatibility, overall dimensions, and dual-wheel spacing rather than assuming any 16-inch radial can take its place.

The right choice depends on the truck’s exact sub-model and the kind of setup already on it. A 1991 Dodge Trucks D350 Base uses a 235/85R16 radial, while the DRW version can use either a 215/85R16 radial or a 750-16 bias-ply. That means some trucks are already aligned with a modern radial path, while others may be retaining a traditional bias-ply format.

Bias-ply often appeals to owners preserving a more vintage truck presentation, especially in 750-16. Radial choices are more in line with modern sizing conventions. Before changing construction on a DRW truck, inspect the actual wheels, confirm the current size, and make sure the tire’s dimensions and spacing work with the truck’s clearance and intended hauling use.

Start with the truck’s exact sub-model and the wheels currently on it. A 1991 Dodge Trucks D350 DRW may be running 750-16 bias-ply, while other D350 fitments are radial. Converting from bias-ply to radial should be treated as a setup change, not just a simple size swap, even though the covered fitments all use 16-inch rims.

Wheel width, dual-wheel spacing, steering clearance, and the truck’s loaded use all deserve attention before making the switch. It also helps to compare the tire’s section width and overall dimensions where available, then inspect suspension and alignment condition so the new construction works with the truck rather than creating clearance or wear issues.

Begin with the truck’s exact fitment path: DRW models use 215/85R16 radial or 750-16 bias-ply, while the Base model uses 235/85R16 radial. After confirming size, the next factors are construction type, rim compatibility, sidewall style, load needs, and whether the truck is being kept in a more traditional appearance or a more modern working setup.

A 750-16 buyer has the broadest range of visual and functional choices, from classic bias-ply blackwalls and wide whitewalls to truck-oriented traction and transport patterns. A 235/85R16 buyer is making a narrower radial choice. Matching the tire to the truck’s actual wheels and expected use is more useful than choosing by appearance alone.

Sidewall choices vary by tire size on the 1991 Dodge Trucks D350. In 750-16, available styles include blackwall and wide whitewall. In 235/85R16, the available radial option uses RWL, or raised white letters. Those differences make sidewall treatment part of the tire decision rather than just a cosmetic detail.

A wide whitewall can push the truck toward a more restoration-oriented or custom presentation, while blackwall truck tires keep a more utilitarian look. Raised white letters introduce a later-style radial appearance. The right sidewall is usually the one that matches the truck’s intended character without pulling you away from the correct size and wheel requirements.

Available brands for 1991 Dodge Trucks D350 tire fitments include Firestone, Lester, BFGoodrich, and STA. Brand variety is strongest in the 750-16 size, where choices span classic bias-ply passenger-style designs and heavier-duty truck patterns. The 235/85R16 fitment is represented by BFGoodrich in the All Terrain TA KO2 radial series.

Brand matters most when it helps you narrow the tire’s character rather than treating one name as universally right. Some D350 owners will be choosing among traditional bias-ply styles for visual presentation, while others need a truck-oriented tread or a modern radial. Comparing construction, sidewall style, and wheel-width suitability usually answers more than the brand alone.

For a period-style 1991 Dodge Trucks D350, the most appearance-driven choice is usually the 750-16 bias-ply fitment used on the DRW configuration. That size opens the door to traditional blackwall and wide whitewall presentations, along with classic bias-ply series and truck-oriented patterns that suit an older visual character.

The best visual direction depends on how the truck is being presented. A work-truck look may lean toward blackwall truck patterns, while a more styled build may favor a whitewall treatment. Owners chasing exact restoration accuracy should compare tire appearance against marque references, photos, and vehicle-specific documentation before settling on a sidewall style.

Tire construction changes the look of a restored 1991 Dodge Trucks D350 as much as it changes the fitment path. A 750-16 bias-ply gives the truck a more traditional numeric truck-tire presentation, while 215/85R16 and 235/85R16 radials bring a more modern metric look. Sidewall treatments can further shift the truck’s overall character.

That visual difference matters most on a truck built around an era-appropriate stance and wheel setup. Bias-ply and radial tires can suggest very different restoration goals even when they share the same 16-inch rim diameter. Matching the tire’s profile and sidewall treatment to the truck’s intended finish usually produces a more coherent result than choosing by size alone.

Yes, modifications can affect tire fitment on a 1991 Dodge Trucks D350 even when the tire size looks correct on paper. Wheel changes, altered ride height, suspension work, and body modifications can all change clearance. That is especially important on a DRW truck, where tire spacing and wheel setup deserve close attention.

A truck that has been updated over the years may no longer match its original fitment path exactly. Checking wheel width, actual tire-to-body clearance, steering travel, and rear-wheel spacing before installation helps avoid rubbing or mismatch problems. Any time the truck has been modified, the tire decision should start at the wheel and suspension, not just the sidewall size.

Before driving a 1991 Dodge Trucks D350 on new tires, inspect the wheels for damage or excessive corrosion, make sure the tire size matches the truck’s sub-model, and confirm proper inflation for the tire being used. It also helps to check valve stems, lug torque, and basic clearance at the fenders, steering components, and suspension.

A short test drive should be followed by another visual inspection, especially on a DRW setup or any truck with older wheels. Look for rubbing marks, uneven seating, or air loss. Since D350 trucks are often used for real work, it is wise to verify that the selected tire also matches the way the truck will be loaded and driven.

Collector-use tires on a 1991 Dodge Trucks D350 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of sun, moisture, and ozone exposure. Low-mileage trucks can still develop tire-age problems, so condition matters just as much as remaining tread depth.

Routine checks are especially important when the truck spends more time parked than driven. Moving the truck occasionally, watching for slow air loss, and storing it on a clean, dry surface all help preserve the tires. Before a longer drive, inspect the full set closely and pay extra attention to older bias-ply tires or any truck still using its long-established wheel setup.
