1981 Dodge Vans Tire Fitment Guide

1981 Dodge Vans use eight sizes across three models. The B150 uses 195/75R15, 205/75R15, 225/75R15, and 235/75R15. The B250 uses 225/75R15 and 235/75R15. The B350 uses 8.00R16.5, 800-16.5, 875-16.5, and 8.75R16.5. The B150 and B250 stay on 15-inch wheels, while the B350 moves to 16.5-inch wheels, so the first fitment question is always which van model you have.

That split matters because a buyer cannot treat all 1981 Dodge Vans as one tire application. If you own a B150 or B250, you are choosing among 15-inch radial sizes with different widths and sidewall styles. If you own a B350, you need to stay within the heavy-duty 16.5-inch family and decide whether a radial or bias-ply truck tire better matches your goals. Verify the actual wheel diameter before ordering, especially on vans that may have changed hands or been modified over the years.

On a 1981 Dodge Vans tire, 195/75R15 is a metric radial size. The 195 is the nominal section width in millimeters, 75 is the aspect ratio, the R means radial construction, and 15 is the wheel diameter in inches. Within the 1981 Dodge van range, this size belongs to the B150 and mounts on rims from 5 to 7 inches wide where rim-width guidance is published.

That code is useful because it quickly tells you this is part of the lighter-duty 15-inch fitment group, not a B350 heavy-duty size. It also helps explain why the available tires lean toward traditional whitewall radial designs rather than truck-style blackwall casings. If your B150 still has its original-style 15-inch wheels, this size sits at the narrower end of that model's range and is worth comparing with 205/75R15, 225/75R15, and 235/75R15 before making a final choice.

No. 1981 Dodge Vans split into two distinct wheel and tire families. B150 and B250 models use 15-inch radial sizes, while the B350 uses 16.5-inch tires in both radial and bias-ply constructions. Even within the 15-inch group, the B150 has four sizes and the B250 shares only the two larger ones, so the full-size Dodge van range was not standardized around one tire code.

That means model identification comes before any discussion of sidewall style or construction preference. A buyer looking at a B350 one-ton van needs to focus on wheel diameter and heavy-duty tire type first, while a B150 or B250 owner can compare whitewall width, tread style, and overall stance within the 15-inch radial family. When a van has been converted, customized, or repainted, checking the model tag and the current wheel itself is the safest starting point.

Those two sizes belong to the 1981 Dodge Vans B350 and share the same 16.5-inch wheel diameter, but they differ in construction. The 8.00R16.5 is a radial truck size, while the 800-16.5 is a numeric bias-ply truck size. That makes the choice less about the wheel diameter and more about whether you want a radial heavy-duty tire or a traditional bias-ply truck tire on your one-ton van.

A B350 owner pursuing a more period-style commercial look will often stay with the bias-ply 800-16.5 family, especially when blackwall truck appearance matters. A driver who wants to remain in the B350's 16.5-inch size group but prefers radial construction may gravitate toward 8.00R16.5 instead. Confirm the exact size already on the van and the wheel diameter stamped on the wheel before making the switch, since 15-inch and 16.5-inch applications are not interchangeable.

1981 Dodge Vans cover a wide spread of sidewall styles, but the choices depend on size and model. The 15-inch radial B150 and B250 sizes include narrow whitewall and wide whitewall treatments, with goldline available in 205/75R15 and raised white letters available in 235/75R15. The B350's 800-16.5 and 875-16.5 bias-ply truck tires are blackwall only, which aligns with the heavier commercial character of the one-ton vans.

That variety lets buyers tune the van's appearance to its role. Passenger vans, custom vans, and conversion vans often look most at home with a whitewall treatment, while an all-terrain or blackwall look can push the van toward a more utilitarian stance. If authenticity is the priority, sidewall style matters almost as much as size because a one-ton work van and a lighter passenger-oriented B150 seldom wore the same visual treatment even when they came from the same model year.

1981 Dodge Vans are covered by Coker Classic, American Classic, BFGoodrich, Tornel, Maxxis, and STA, depending on size. The 15-inch radial sizes used on the B150 and B250 are where most of the brand variety appears, including several classic-style whitewall offerings and one raised-white-letter all-terrain option in 235/75R15. The B350's 800-16.5 and 875-16.5 bias-ply truck sizes are handled by STA in blackwall form.

Brand choice on these vans is tied closely to use case and appearance. A B150 owner comparing whitewall widths has more brand flexibility than a B350 owner shopping for a traditional 16.5-inch truck casing, where the decision tends to narrow around construction and tread character. It is smart to pick your exact size first, then compare the sidewall style and load range characteristics within that size instead of starting with the brand name alone.

Rim-width guidance varies by size on 1981 Dodge Vans. For the B150, 195/75R15 fits 5 to 7-inch rims, 205/75R15 fits 5.50 to 7.50-inch rims, 225/75R15 fits about 6 to 8-inch rims, and 235/75R15 fits roughly 6 to 8.50-inch rims depending on the tire. For the B350, 800-16.5 is paired with a 6.00 to 6.50-inch rim on versions where that range is published.

Rim width matters because two tires with the same wheel diameter can still behave differently if the wheel is too narrow or too wide for the casing. That is especially important on older vans, where original wheels may have been replaced during years of service or customized during the conversion-van era. Check the wheel's actual width before settling on a tire size, and use the tire's own approved range rather than assuming every 15-inch or 16.5-inch wheel is suitable.

Original 1981 Dodge Vans wheels can only be shared among tire sizes that match the same wheel diameter. Within the B150 and B250 family, the 195/75R15, 205/75R15, 225/75R15, and 235/75R15 sizes all mount on 15-inch wheels. Within the B350 family, 8.00R16.5, 800-16.5, 875-16.5, and 8.75R16.5 all belong to 16.5-inch wheels.

Diameter compatibility is only the first checkpoint. Wheel width still has to suit the exact tire you want to run, and that can narrow the field even when the rim diameter matches. A B150 or B250 wheel that works well with 195/75R15 may not automatically be the best match for a wider 235/75R15. Confirm both diameter and width at the wheel itself before moving between sizes, especially on vans that have spent decades in mixed private and commercial use.

A stored 1981 Dodge Vans should be kept away from direct sunlight, ozone sources such as electric motors and battery chargers, and prolonged dampness that can age both rubber and wheels. Maintain inflation, keep the van on a clean dry surface, and move it periodically so the tires do not sit under the same load point for months at a time. Static storage is especially hard on older van tires because their sidewalls and casings carry substantial weight even when the vehicle is parked.

If the van will sit for an extended season, some owners use tire cradles or place the vehicle on stands to reduce constant load, especially on heavier B350 models. Regular repositioning is still useful for B150 and B250 vans with whitewall tires, since preserving appearance is often part of the goal. Clean tires with mild soap and water only, and keep solvents, petroleum dressings, and harsh cleaners away from the sidewalls.

Tires on a 1981 Dodge Vans should be judged more by age and condition than by mileage. On collector and hobby vehicles, a good rule is to begin careful age-based evaluation around five to seven years and to consider replacement as tires approach ten years, even if the tread still looks strong. The DOT date code on the tire helps establish age, but sidewall cracking, hardness, vibration, and long periods of static storage matter just as much.

That approach fits old vans especially well because many spend long stretches parked, then return to use for road trips, cruises, or hauling. A low-mile tire can still be too old for confident service, particularly on a heavier vehicle that asks more from the casing under braking and cornering. If the age of the tire and the age of the restoration no longer match, replace the tire first and let cosmetics come second.

Tires on a 1981 Dodge Vans should be inspected before every drive and again before any extended outing. Look for sidewall cracking, uneven wear, punctures, cuts, bulges, and signs of weathering around the bead area. Pressure retention matters too, because a van that has sat for several weeks can lose enough air to change its stance and handling before you notice it on the road.

A quick walk-around is usually enough for casual use, but a longer trip deserves a closer check of the spare, valve stems, and wheel condition as well. Heavier B350 vans deserve extra attention because load and heat build quickly when an underinflated tire is carrying work-van weight. If a tire has been parked in one position for a long time, drive gently at first and feel for vibration that might suggest age, flat-spotting, or a deeper casing issue.

By 1981, radial tires were a normal fitment direction for mainstream American vans, and the B150's size range reflects that with 195/75R15, 205/75R15, 225/75R15, and 235/75R15 options. That does not mean every B150 left the factory with the same exact size, since load rating, body use, and market presentation could influence the final fitment. Whitewall styling also fit the era well on passenger and conversion-oriented vans, but the exact original treatment can vary by how the van was ordered.

For a restoration, start by confirming the size on the original placard, build information, or surviving factory paperwork rather than assuming the widest 15-inch size is automatically correct. Then decide how closely you want to mirror the van's first-delivery appearance, including whitewall width. Marque clubs, original brochures, and unrestored survivor vans are the best references when you want market- and trim-specific confirmation beyond the basic 1981 Dodge Vans size family.

Correct tire fitment absolutely matters when showing a 1981 Dodge Vans, because judges and knowledgeable enthusiasts notice size, construction, and sidewall style quickly. A B150 or B250 shown as a period passenger or custom van may look out of character on a modern raised-white-letter truck tire, while a B350 work van can lose credibility if dressed in a sidewall treatment that does not fit its intended role. The tire is one of the largest visible details on the vehicle, so it strongly affects first impressions.

The practical standard is to match the van's mission and presentation, not just its wheel diameter. A show-focused van usually benefits from tire choices that support the vehicle's era, stance, and body style without drawing attention as a modern substitute. For formal judging, always check event-specific standards with Dodge and Mopar clubs, because some venues are stricter about radial-versus-bias construction and sidewall cosmetics than others.

For 1981 Dodge Vans B350 fitments in 800-16.5, STA Super Transport and STA Traxion are both bias-ply blackwall truck tires, but they are not the same product line. Super Transport carries a published maximum load of 2,045 pounds at 60 psi and a published rim-width fitment of 6.00 to 6.50 inches, while the Traxion version in that size is a lighter tire by weight. In 875-16.5, Traxion and Transport Highway continue that blackwall bias-ply heavy-duty theme in a larger size class.

That makes the comparison more about service character and exact sizing than about appearance, since all of these B350 truck tires present a straightforward commercial look. Owners restoring a one-ton van should compare the existing size on the wheel, the intended use of the van, and any published load or rim-width guidance before choosing between the STA lines. Staying within the correct 16.5-inch B350 family matters more than chasing cosmetic differences that are minor in this commercial category.

1981 Dodge Vans tires can be appropriate for highway use when the tires are in good condition, correctly inflated, and matched to the van's actual size and wheel. One published speed marking appears in 235/75R15, where the BFGoodrich All-Terrain T/A KO2 carries an S rating, which corresponds to a 112 mph ceiling. Many other products in these sizes do not show a speed letter in the size marking, so the safe approach is to treat each tire by its own sidewall and manufacturer guidance rather than assuming all products in one size have the same speed capability.

In real-world vintage-van driving, tire condition and the van's overall mechanical state usually matter more than chasing high top-speed capability. A 1981 full-size Dodge van has older chassis, braking, and steering characteristics than a modern vehicle, and those factors should shape cruising speed and trip planning. Before regular highway use, confirm the exact tire fitted, inspect for age and cracking, and match the tire's character to the kind of driving you actually do.

Inflation pressure on 1981 Dodge Vans depends on the exact size and tire. Published maximum load and pressure figures include 1,477 pounds at 32 psi for some 195/75R15 tires, 1,598 pounds at 35 psi for some 205/75R15 tires, 2,094 pounds at 32 psi for some 225/75R15 tires, 2,271 pounds at 32 psi for some 235/75R15 tires, and 2,045 pounds at 60 psi for one 800-16.5 application. Those are tire ratings, not a universal van setting.

Use the Dodge factory recommendation as the starting point for the vehicle, then confirm it against the reproduction or replacement tire's own sidewall and manufacturer guidance. Do not transfer a pressure figure from one size to another just because the wheel diameter is the same, and do not set every B150, B250, and B350 tire alike. The correct pressure depends on tire size, construction, and how the van is actually being used.

Before a longer drive in a 1981 Dodge Vans, inspect every tire for cracks, cuts, bulges, exposed cords, uneven wear, and proper pressure, then check the spare as carefully as the four on the ground. Look closely at valve stems, especially on older wheels, and make sure the tire size on the van matches the wheel diameter you expect. A B350 deserves extra attention because 16.5-inch heavy-duty tires and work-van loads can hide problems until heat builds up on the road.

Tires are only one part of the pre-trip picture on an older van, so include brakes, steering play, fluids, lighting, and wheel fastener condition in the routine. If the van has been sitting, start with a shorter local drive and recheck the tires afterward for pressure loss or fresh signs of distress. That habit helps you catch a casing or wheel issue in the driveway instead of on the shoulder.
