The 1991 Dodge Trucks W350 sits squarely in the era of heavy-duty Dodge pickups built for real work, with one-ton capability and the stout four-wheel-drive character that makes these trucks appealing to collectors and active-use owners alike. Tire choice on this truck is more about confirming the correct working fitment than sorting through multiple factory sizes, because the W350 uses a 235/85R16 radial on a 16-inch rim. In practice, that means the decision centers on load-capable radial construction, sidewall presentation, and intended use. For a truck that may still tow, haul, or see back-road service, wheel condition, rim width, and overall tire condition deserve as much attention as appearance.
Which Tire Size Is Right for The 1991 Dodge Trucks W350
The 1991 Dodge Trucks W350 uses one primary tire size: 235/85R16. It is a radial fitment on a 16-inch rim, and the covered Base sub-model uses that same size. That keeps the size question straightforward, so the real choice becomes selecting the right tire within that fitment and confirming that the truck still has the correct wheel setup for a heavy-duty 16-inch radial.
A 235/85R16 size reads as a metric radial with a 235-millimeter nominal section width, an 85-series aspect ratio, and fitment for a 16-inch wheel. On the 1991 Dodge Trucks W350, that format matches the truck’s primary radial tire fitment and suits the heavy-duty, road-and-work use expected from a one-ton 4x4 pickup. Available choices in this size can include details that matter to truck owners, such as raised white letter sidewalls, all-terrain-style construction, load capacity, and rim-width compatibility. It is the right starting point for keeping the truck in its proper fitment range while checking that the wheels remain correct for the tire.
Sub-model fitment is straightforward for the 1991 Dodge Trucks W350. The covered sub-model uses the same primary tire size, so selecting a tire is less about trim differences and more about confirming wheel condition, intended use, and the type of radial tire you want on the truck.

Tire Size & Fitment
What tire size fits a 1991 Dodge Trucks W350?
The 1991 Dodge Trucks W350 uses a 235/85R16 radial tire. That is the primary fitment for this truck, and the covered W350 Base sub-model uses the same size as well, which keeps fitment straightforward compared with trucks that have multiple tire-size variations.
Even with a single primary size, it is still smart to confirm what is actually on the truck before replacing tires. Older pickups are often fitted with different wheels over time, so checking the wheel diameter, wheel width, and the clearance around suspension and body components helps ensure the replacement tire matches the truck’s current setup.
What size rim does a 1991 Dodge Trucks W350 use?
The 1991 Dodge Trucks W350 uses a 16-inch rim with its 235/85R16 tire fitment. A product available in this size also calls for a rim-width range of 6.0 to 7.5 inches, which is useful when confirming that the wheel is appropriate for a heavy-duty radial truck tire.
Rim diameter is the first number to verify because a 16-inch tire only belongs on a 16-inch wheel. Width matters too, especially on older work trucks that may have seen wheel swaps, so checking both measurements helps avoid issues with tire shape, sidewall behavior, and overall fit once the tire is mounted.
Does the 1991 Dodge Trucks W350 Base use the same tire size?
Yes. The 1991 Dodge Trucks W350 Base uses the same 235/85R16 radial tire size as the overall W350 fitment covered here. There is no separate alternate primary size for that sub-model, so the main fitment question does not change from one covered W350 configuration to another.
That consistency makes the buying process simpler, but it does not remove the need to inspect the truck itself. A replacement should still be matched to the actual wheels on the vehicle, and any aftermarket suspension, wheel, or body changes should be checked so the tire has proper clearance during steering, compression, and normal road use.
Choosing the Right Tire
What should I consider when choosing a 235/85R16 tire for a 1991 Dodge Trucks W350?
Start with the correct size, which is 235/85R16, and confirm that the tire is built for the kind of service the W350 may still see. Construction, load capacity, rim-width compatibility, sidewall style, and overall tread character all matter more here than chasing appearance alone on a one-ton four-wheel-drive truck.
A buyer using the truck for hauling, towing, or regular road miles should look closely at the tire’s stated specifications, including the wheel-width range and load figure. A truck kept for show or occasional use may put more emphasis on visual presentation, but wheel condition, age-related wear, and the truck’s actual operating demands still deserve equal attention.
What sidewall styles are available for 1991 Dodge Trucks W350 tires?
An available 235/85R16 tire for the 1991 Dodge Trucks W350 comes with an RWL sidewall, meaning raised white letters. That gives the truck a more assertive period-truck look than a plain blackwall and suits owners who want a tire presentation that feels at home on a rugged early-1990s 4x4.
Sidewall style is mostly an appearance decision, but it should be secondary to fitment and service requirements. On a W350, the more important checks are still size, radial construction, wheel compatibility, and load capability. Once those are right, sidewall treatment becomes a useful way to tune the truck’s finished look without changing the basic fitment.
What brands offer tires for the 1991 Dodge Trucks W350?
BFGoodrich offers a 235/85R16 tire for the 1991 Dodge Trucks W350. The available tire is part of the All Terrain T/A KO2 line, giving the truck a radial all-terrain option that aligns well with the heavy-duty, four-wheel-drive nature of the W350 platform.
Brand alone should not decide the purchase. The better approach is to compare the tire’s actual specifications and character with how the truck will be used, including wheel-width compatibility, sidewall styling, and load needs. That matters especially on an older one-ton truck, where the correct working fitment is more important than picking by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Dodge Trucks W350?
A period-style approach for a 1991 Dodge Trucks W350 starts with the correct 235/85R16 radial size on the proper 16-inch wheel. Since this truck’s fitment is already a radial rather than a bias-ply application, the appearance decision is more about tread character and sidewall presentation than about preserving an earlier tire construction style.
An all-terrain radial with raised white letters can suit the visual character of a work-oriented four-wheel-drive Dodge from this era. Owners aiming for a highly exact restoration should still compare tire appearance against photographs, brochures, marque references, or other truck-specific historical sources rather than assuming any current tire in the right size matches original presentation.
Does correct tire fitment matter for a 1991 Dodge Trucks W350 restoration?
Yes, correct tire fitment matters on a 1991 Dodge Trucks W350 restoration because tire size strongly affects stance, wheelwell fill, and the truck’s overall visual balance. Using the proper 235/85R16 size helps maintain the heavy-duty look associated with a one-ton Dodge pickup of this period.
Fitment also matters mechanically, not just visually. The right size and wheel combination helps preserve sensible clearance and load-carrying confidence, while an incorrect wheel or tire can make even a well-restored truck look and feel out of place. Restoration-minded buyers should verify both wheel dimensions and the condition of older rims before mounting new tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Dodge Trucks W350?
Yes, modifications can affect tire fitment on a 1991 Dodge Trucks W350 even when the intended tire size remains 235/85R16. Changes such as aftermarket wheels, altered wheel offset, suspension lifts, lowering, replacement springs, or body modifications can all influence how the tire sits and whether it clears properly in use.
A truck that has been changed from stock should be measured rather than assumed correct. Checking wheel diameter, wheel width, steering clearance, suspension travel, and space around the fenders helps prevent rubbing or shape issues after installation. That is especially important on an older four-wheel-drive one-ton truck that may have been modified for work or off-road use.
What should I inspect before driving a 1991 Dodge Trucks W350 on new tires?
Before driving a 1991 Dodge Trucks W350 on new tires, inspect the wheels for damage or corrosion, confirm the tire size matches the intended 235/85R16 fitment, and make sure the tires are mounted on suitable 16-inch rims. Tire pressure, valve stems, lug hardware, and visible clearance around suspension and body components all deserve attention.
The rest of the truck matters too, especially on a vintage heavy-duty pickup. Steering components, brakes, shocks, springs, and alignment condition can affect how new tires behave on the road. A short, careful road test is a smart final step, giving the owner a chance to listen for rubbing, feel for vibration, and verify stable straight-line tracking.
How should 235/85R16 tires on a collector 1991 Dodge Trucks W350 be maintained?
235/85R16 tires on a collector 1991 Dodge Trucks W350 should be checked regularly for air pressure, tread wear, sidewall cracking, cuts, bulges, and signs of slow air loss. Older trucks that see limited mileage often need condition-based inspection more than mileage-based inspection, because age and storage environment can matter as much as road use.
Storage practices help preserve a low-use truck’s tires. Keeping the W350 away from prolonged sunlight, excess heat, standing moisture, and ozone sources can reduce premature deterioration, and moving the truck periodically helps avoid long-term flat spotting. Before a longer drive, inspect the tires closely and confirm the wheels and suspension are still in sound operating condition.
