The 1991 Dodge Vans B350 sits in the era when full-size American vans were expected to handle real passenger, cargo, and work duty without giving up highway comfort. Whether used as a standard B350, an HD model, or a long-wheelbase Maxi, this van's tire choice affects load support, stance, and everyday drivability more than on many lighter vehicles. The primary fitments here are 225/75R16 and 245/75R16, both radial sizes on 16-inch rims. That keeps the decision focused on matching the correct sub-model and selecting the right LT-style radial specification. For a restoration-minded van or an active hauler, wheel fit, load capacity, and overall clearance all deserve a careful look.
Which Tire Size Is Right for The 1991 Dodge Vans B350
The 1991 Dodge Vans B350 uses two primary tire sizes, and the right one depends on the exact sub-model. Both are radial tires for 16-inch rims, but the larger 245/75R16 applies to the B350 Maxi with 9000 GVWR, while other covered B350 versions use 225/75R16. Before choosing a tire, confirm the van's specific sub-model and wheel setup so the size matches the vehicle's intended load and clearance requirements.
225/75R16 is a modern metric radial size in which 225 identifies the section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 16 is the rim diameter in inches. On the 1991 Dodge Vans B350, this size serves the Base, HD, and Maxi sub-models that use the standard 16-inch fitment. Available choices in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter styling and LT-duty construction. This size makes sense when the van's original sub-model fitment, wheel width, and intended carrying role all line up with the 225-series setup.
245/75R16 follows the same metric radial format, with a 245-millimeter nominal section width, a 75-series profile, radial construction, and a 16-inch rim diameter. For the 1991 Dodge Vans B350, this larger primary fitment is tied to the B350 Maxi with 9000 GVWR, making sub-model identification especially important before ordering. In this size, BFGoodrich offers the All-Terrain T/A KO2 with raised white letter sidewalls and LT-type load capability. It is the size to evaluate when the van carries the heavier-duty Maxi configuration and needs the matching wheel-width and clearance envelope.
Sub-model fitment matters on the 1991 Dodge Vans B350 because most covered versions use one size, while the higher-GVWR Maxi uses another. Checking the exact sub-model first helps separate a standard 225/75R16 application from the 245/75R16 fitment used on the heavier-duty Maxi configuration.

1991 Dodge Vans B350 Base
The 1991 Dodge Vans B350 Base uses the 225/75R16 radial size on a 16-inch rim. Tire selection here centers on choosing an LT-style radial that matches the wheel width and intended use of the van without stepping into the larger Maxi 9000 fitment.
The 1991 Dodge Vans B350 HD also uses the 225/75R16 radial tire size. That keeps selection straightforward, but wheel width, load needs, and any later wheel changes should still be checked before choosing among available LT-type radial options.
The 1991 Dodge Vans B350 Maxi uses the 225/75R16 radial fitment in this application. Owners can focus on selecting the right LT-spec tire and confirming that the van has not been changed over to wheels or suspension components that alter clearance or carrying requirements.
The 1991 Dodge Vans B350 Maxi (GVWR 9000) uses the larger 245/75R16 radial size. That makes this version the one that most needs careful identification, since choosing the heavier-duty Maxi tire size affects load support, wheel-width compatibility, and clearance compared with the 225-series setup.
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 1991 Dodge Vans B350 Tires for Sale
Available 1991 Dodge Vans B350 tires center on BFGoodrich All-Terrain T/A KO2 options in both primary sizes. The comparison is less about brand variety and more about matching the correct 225/75R16 or 245/75R16 size, LT load specification, raised white letter sidewall, and wheel-width range to the van.
These 1991 Dodge Vans B350 FAQs focus on the size split between sub-models, 16-inch rim fitment, LT radial selection, appearance details such as raised white letters, and the checks worth making before putting a full-size van back into regular road use.
Tire Size & Fitment
What tire size fits a 1991 Dodge Vans B350?
A 1991 Dodge Vans B350 uses either 225/75R16 or 245/75R16, depending on the sub-model. The Base, HD, and Maxi use 225/75R16 radial tires, while the B350 Maxi with 9000 GVWR uses 245/75R16 radial tires. Both sizes are built for 16-inch rims.
The key step is identifying the exact version of the van before choosing tires. A standard B350 and a higher-GVWR Maxi are not using the same primary size, so it is worth checking the model designation, existing tire placard information, wheel width, and the actual wheel setup if the van has been changed over the years.
What size rim does a 1991 Dodge Vans B350 use?
The covered 1991 Dodge Vans B350 tire fitments use a 16-inch rim diameter. That applies to both primary tire sizes, 225/75R16 and 245/75R16, so the difference between them is not wheel diameter but the tire's section width and overall dimensions.
Rim diameter is only part of the fitment picture on a full-size van. Wheel width still matters, especially when comparing the 225 and 245 sizes, and any aftermarket wheel should be checked carefully before a tire is chosen. Confirming the stamp on the wheel can prevent ordering a tire that does not suit the rim properly.
Do all 1991 Dodge Vans B350 sub-models use the same tire size?
No. The 1991 Dodge Vans B350 Base, HD, and Maxi use 225/75R16, while the 1991 Dodge Vans B350 Maxi with 9000 GVWR uses 245/75R16. All of these applications are radial and share the same 16-inch rim diameter, but the tire size is not uniform across every sub-model.
That difference matters because the larger 245/75R16 application belongs to a specific heavier-duty Maxi configuration, not the entire B350 range. Matching the tire to the exact van helps maintain the intended load-carrying setup and avoids treating every B350 as though it used the same width and overall tire dimensions.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Dodge Vans B350?
Start with the correct primary size for the van's sub-model: 225/75R16 for the Base, HD, and Maxi, or 245/75R16 for the Maxi with 9000 GVWR. Since the available products are LT-style radials, wheel-width compatibility, load capacity, and the van's actual use matter as much as the size itself.
A B350 used for light cruising may still carry a tire with a very different service character than one chosen for hauling or regular road miles. It also helps to compare the tire's sidewall treatment, weight, and rim-width range, then confirm that the van still has the wheels and suspension arrangement that the chosen size expects.
What sidewall styles are available for 1991 Dodge Vans B350 tires?
The available 1991 Dodge Vans B350 products in these sizes use RWL sidewalls, meaning raised white letters. That gives the van a more assertive light-truck appearance than a plain blackwall and suits the BFGoodrich All-Terrain T/A KO2 offerings available in both primary sizes.
Sidewall styling does not change the underlying fitment, but it does influence how the van looks once mounted. On a preserved or period-flavored B350, raised white letters create a more truck-oriented presentation, so it is worth deciding whether appearance matters as much as load range and wheel compatibility before settling on a tire.
What brands offer tires for the 1991 Dodge Vans B350?
The available products for the 1991 Dodge Vans B350 are from BFGoodrich. In both 225/75R16 and 245/75R16, the offered tire is the BFGoodrich All-Terrain T/A KO2, an LT-style radial with raised white letter sidewalls and 16-inch rim fitment.
With a single brand and series in view, the main comparison is not between manufacturers but between the two proper sizes and their wheel-width and load specifications. That makes it especially important to verify whether the van is a standard B350 application or the Maxi 9000 version before choosing between the available BFGoodrich options.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Dodge Vans B350?
For a period-style 1991 Dodge Vans B350, the starting point is the correct original-type size relationship for the exact sub-model: 225/75R16 for most B350 versions and 245/75R16 for the Maxi with 9000 GVWR. Since these are radial-era vans, staying with the proper LT radial format preserves the vehicle's basic late-model full-size van character.
Appearance still comes down to how the van is being presented. An all-terrain tread and raised white letters create a more rugged visual statement than some owners may want on a restoration-minded project, so it helps to balance period feel, intended use, and the way the finished van should look sitting on its 16-inch wheels.
How does tire construction affect the appearance of a restored 1991 Dodge Vans B350?
On a restored 1991 Dodge Vans B350, tire construction affects both stance and visual character, even when the correct size is used. This van's primary fitments are radial, so keeping a proper radial construction maintains the more modern, late-20th-century look that belongs with a full-size Dodge van of this era.
Tread style and sidewall treatment shape the final impression just as much as construction. A raised white letter LT radial gives the van a noticeably more truck-like presence, while the wrong size can alter the proportions around the wheel opening. Matching the exact sub-model fitment is the best first step toward a convincing restoration-minded presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Dodge Vans B350?
Yes. A 1991 Dodge Vans B350 may no longer have its original wheels, suspension height, or axle setup, and any of those changes can affect tire fitment. That matters even more because this van already uses two different primary tire sizes depending on sub-model, so modified examples deserve a closer look before replacement tires are chosen.
Aftermarket wheels can change width and offset, while suspension changes can affect steering and fender clearance. On a B350, it is smart to inspect the current wheel size, wheel width, and the actual clearance around the tire before assuming the van should stay with the same size that happens to be mounted on it now.
What should I inspect before driving a 1991 Dodge Vans B350 on new tires?
Before driving a 1991 Dodge Vans B350 on new tires, inspect the wheels for correct diameter and condition, confirm lug hardware, and make sure the chosen tire size matches the sub-model. It is also wise to check for suspension wear, steering looseness, and any signs that the van has irregular clearance at full lock or under load.
A fresh set of tires cannot compensate for worn front-end components or damaged wheels. Once the tires are mounted, verify inflation, look for even seating at the bead, and take a short test drive while listening for rubbing or vibration. That extra check is especially valuable on an older full-size van that may have seen heavy service.
How should tires on a collector 1991 Dodge Vans B350 be maintained?
Tires on a collector 1991 Dodge Vans B350 should be inspected regularly for cracking, bulges, cuts, unusual wear, and slow air loss, even if the van is driven only occasionally. Because full-size vans can carry substantial weight, proper inflation and periodic condition checks matter just as much during storage as they do during road use.
Storage habits make a difference on a low-use B350. Keeping the van out of prolonged sunlight, excess moisture, and ozone sources helps protect the rubber, and moving or driving it occasionally can reduce flat-spotting. Before any longer trip, recheck pressure, tread condition, and the spare so the van is ready for real highway service.
