The 1985 Dodge Vans B350 sits in the last generation of Chrysler's longstanding B-series full-size vans, a work-focused platform that served passenger, cargo, and heavy-duty roles with equal familiarity. That matters when choosing tires, because this exact model range spans more than one primary fitment even though every version uses a 16.5-inch wheel. Bias-ply sizes 800-16.5 and 875-16.5 cover most B350 applications here, while the Maxi HD with 9000 GVWR uses an 8.75R16.5 radial. Available choices stay purpose-built and traditional, centered on blackwall truck tires in STA series such as Super Transport, Traxion, and Transport Highway, so selection should follow the van's sub-model and intended use first.
Which Tire Size Is Right for The 1985 Dodge Vans B350
Three primary tire sizes apply to the 1985 Dodge Vans B350, and the right one depends on the exact sub-model rather than the model name alone. All of them use a 16.5-inch rim, but construction differs as well, with 800-16.5 and 875-16.5 in bias-ply form and 8.75R16.5 in radial form. The first step is confirming whether the van is a Base, HD, Maxi, Maxi HD, or Maxi HD with 9000 GVWR.
In 800-16.5, the 800 indicates an approximate 8.00-inch nominal section width and the 16.5 identifies the wheel diameter. This is a bias-ply truck tire size used on certain 1985 Dodge Vans B350 Base applications, giving the van a traditional commercial-tire construction and appearance. Available choices in this size come from STA in Super Transport and Traxion series, both offered as blackwall tires with Military & Truck positioning. It is the size to evaluate when the van is one of the Base versions equipped for the narrower 8.00-inch fitment rather than the wider 8.75-inch setup.
The size code 875-16.5 uses the same older numeric bias-ply convention, with 875 representing an approximate 8.75-inch nominal section width and 16.5 indicating wheel diameter. On the 1985 Dodge Vans B350, this bias-ply size covers the HD, Maxi, and Maxi HD applications, and it also appears on some Base versions. STA offers it in blackwall form through the Traxion and Transport Highway series, giving buyers a choice between different truck-oriented tread families within the correct size. This is the primary fitment to confirm when the van carries the heavier-duty or longer-body B350 configuration.
The 8.75R16.5 size uses an older radial format, with 8.75 indicating nominal section width, R identifying radial construction, and 16.5 showing the wheel diameter. For the 1985 Dodge Vans B350, this radial fitment is tied to the Maxi HD with 9000 GVWR, making it a distinct fitment rather than a general alternative for every B350. Its role is important because it changes the construction choice at the primary-fitment level, not just the brand or tread pattern. Buyers should verify the exact GVWR-specific sub-model before treating the radial size as applicable to another B350 configuration.
Sub-model fitment matters on the 1985 Dodge Vans B350 because tire size changes across the range even though the wheel diameter stays at 16.5 inches. Checking the exact B350 version is the quickest way to avoid choosing a tire that belongs to a heavier-duty or GVWR-specific application.

1985 Dodge Vans B350 Base
The 1985 Dodge Vans B350 Base can use either 800-16.5 or 875-16.5 in bias-ply construction, so this is the one B350 sub-model here that requires especially careful confirmation. Tire selection should start with the actual wheel and tire setup on the van before narrowing down series and load-oriented commercial-style options.
The 1985 Dodge Vans B350 HD uses the 875-16.5 bias-ply size on a 16.5-inch wheel. That keeps the tire decision focused on choosing the right truck-style product within that size rather than sorting through multiple primary fitments.
The 1985 Dodge Vans B350 Maxi uses the 875-16.5 bias-ply tire size. For this sub-model, the main decision is choosing among the available blackwall commercial-style tires while keeping the original size and wheel diameter in line with the van's setup.
The 1985 Dodge Vans B350 Maxi HD uses the 875-16.5 bias-ply size in the standard heavy-duty configuration covered here. That makes selection more straightforward, with attention centered on staying in the correct size and comparing the available STA truck tire series.
The 1985 Dodge Vans B350 Maxi HD (GVWR 9000) stands apart by using 8.75R16.5 radial construction instead of the bias-ply sizes used elsewhere in the range. Tire choice for this sub-model starts with confirming that GVWR-specific application, since the construction and size designation are different from the other B350 variants.
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 Dodge Vans B350 Tires for Sale
Available 1985 Dodge Vans B350 tire choices focus on STA truck tires in the 800-16.5 and 875-16.5 bias-ply sizes. The product grid lets you compare blackwall options across Super Transport, Traxion, and Transport Highway series, along with rim-width, load, and weight details where they apply.
Common questions for the 1985 Dodge Vans B350 usually center on sub-model-specific tire size, 16.5-inch rim fitment, bias-ply versus radial construction, and how to choose the right truck tire for restoration, service, and safe road use.
Tire Size & Fitment
What tire size fits a 1985 Dodge Vans B350?
The 1985 Dodge Vans B350 uses three primary tire sizes across its covered configurations: 800-16.5, 875-16.5, and 8.75R16.5. The 800-16.5 and 875-16.5 sizes are bias-ply fitments, while 8.75R16.5 is a radial fitment used on the Maxi HD with 9000 GVWR.
Choosing the right size starts with confirming the exact sub-model, because B350 fitment is not the same across the full range. A Base van may use either 800-16.5 or 875-16.5, while the HD, Maxi, and Maxi HD use 875-16.5, and the Maxi HD with 9000 GVWR uses 8.75R16.5.
What size rim does a 1985 Dodge Vans B350 use?
The covered tire fitments for the 1985 Dodge Vans B350 all use a 16.5-inch rim diameter. That includes the 800-16.5 and 875-16.5 bias-ply sizes as well as the 8.75R16.5 radial size used on the GVWR-specific Maxi HD version.
Rim diameter is only one part of the fitment check, especially on an older full-size van that may have seen wheel changes over the years. It is smart to confirm the actual wheel on the van, then compare the tire's rim-width requirements and make sure there is adequate clearance at steering lock and under load.
Do all 1985 Dodge Vans B350 sub-models use the same tire size?
No. The 1985 Dodge Vans B350 range uses more than one primary tire size, and the variation follows the exact sub-model. Base versions can use 800-16.5 or 875-16.5, HD, Maxi, and Maxi HD use 875-16.5, and the Maxi HD with 9000 GVWR uses 8.75R16.5 radial construction.
That means the van's trim and duty rating matter more than the B350 badge alone. Before ordering tires, confirm whether the vehicle is a standard Base, a heavier-duty model, or the GVWR-specific Maxi HD, then check the existing wheel and tire setup so the chosen size matches the van's actual configuration.
Choosing the Right Tire
What should I consider when choosing a 875-16.5 tire for a 1985 Dodge Vans B350?
Start by confirming that 875-16.5 is the correct primary size for the van's exact sub-model, since this size applies to the HD, Maxi, and Maxi HD and also appears on some Base versions. Within that size, the available choices are bias-ply STA truck tires in blackwall form.
The next comparison is product character rather than fitment format. Looking at series such as Traxion and Transport Highway can help narrow the choice, and it also helps to compare any available rim-width, load, and weight details against the wheel on the van and the way the vehicle will actually be used.
What brands offer tires for the 1985 Dodge Vans B350?
The available products for the covered 1985 Dodge Vans B350 fitments come from STA. That includes 800-16.5 options in the Super Transport and Traxion series and 875-16.5 options in the Traxion and Transport Highway series.
Since the brand selection here is focused rather than broad, the real buying decision is usually between tire series and fitment details within the correct size. Once the exact B350 sub-model and tire size are confirmed, compare the available truck-oriented choices by construction, sidewall style, rim-width compatibility, and any load information shown for that tire.
What tire series are available for the 1985 Dodge Vans B350?
The 1985 Dodge Vans B350 tire options here include STA Super Transport, STA Traxion, and STA Transport Highway series. Super Transport appears in 800-16.5, Traxion is available in both 800-16.5 and 875-16.5, and Transport Highway is available in 875-16.5.
Series names matter because they help separate one truck-style tire choice from another after the correct fitment has been established. On a B350, it makes sense to first verify the van's exact size, then use the series differences alongside sidewall style, weight, and any published load or rim-width details to narrow the final selection.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Dodge Vans B350?
A period-style approach starts with the correct primary size for the exact 1985 Dodge Vans B350 sub-model. That means 800-16.5 or 875-16.5 in bias-ply form for the covered standard applications, while the Maxi HD with 9000 GVWR uses 8.75R16.5 radial construction as its primary fitment.
Once the size and construction are settled, appearance stays straightforward because the available products are blackwall truck tires with a traditional commercial presentation. For a restoration where exact historical accuracy matters beyond size and general look, it is worth checking vehicle-specific reference material and surviving original examples before making the final choice.
Does correct tire fitment matter for a 1985 Dodge Vans B350 restoration?
Yes. Correct tire fitment has a strong effect on how a restored 1985 Dodge Vans B350 sits, looks, and functions, especially because this model range includes more than one primary size and both bias-ply and radial construction depending on the exact sub-model. A wrong size can change the van's overall presentation even when the wheel diameter is correct.
Restoration-minded owners should confirm the exact B350 configuration before selecting tires and should avoid assuming that one 16.5-inch fitment applies across the whole line. Keeping the proper size and construction in place is usually the best starting point, then sidewall style and tire series can be chosen to support the intended finished appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Dodge Vans B350?
Yes. Even when a 1985 Dodge Vans B350 originally used one of the correct 16.5-inch fitments, changes such as aftermarket wheels, altered wheel width, suspension work, or body modifications can affect whether that tire still suits the van. Clearance at the front suspension and fender openings is especially important on a full-size van.
A modified vehicle should be checked as it sits today rather than by model name alone. Measuring the actual wheel, confirming the mounted tire size, and looking for rubbing marks or limited clearance under steering and load are sensible steps before replacing the tires with another bias-ply or radial in the same general size family.
What should I inspect before driving a 1985 Dodge Vans B350 on new tires?
Before road use, inspect the wheels for correct diameter and condition, verify that the new tires match the intended size for the van's sub-model, and check that each tire is seated properly and inflated appropriately for its application. It also helps to look over valve stems, lug hardware, and overall tread and sidewall condition.
A short, careful test drive is a smart final step on an older B350. Listen for rubbing, watch for pull or vibration, and recheck clearances after the van has settled under its own weight. On collector or low-use vehicles, an overall brake and suspension inspection is just as important as the tire installation itself.
How should 875-16.5 tires on a collector 1985 Dodge Vans B350 be maintained?
Collector-use 875-16.5 tires on a 1985 Dodge Vans B350 should be kept clean, properly inflated, and inspected regularly for cracking, bulges, cuts, uneven wear, and air loss. Bias-ply truck tires also benefit from routine visual checks after storage because collector vans often sit longer than regularly used vehicles.
Storage conditions matter almost as much as mileage. Parking away from prolonged sunlight, moisture, and ozone sources can help preserve tire condition, and moving the van occasionally can reduce long-term flat spotting. Before a longer trip, check pressure, inspect tread and sidewalls closely, and make sure the wheel and suspension hardware remain in sound condition.
