The 1978 Dodge Van range reflects an era when Dodge sold hardworking vans in several forms, from compact people-and-cargo haulers to full-size Tradesman workhorses. By the late 1970s, these vans served everyone from contractors and delivery fleets to custom-van owners who cared as much about stance and style as utility. Across 2 models, 11 tire sizes appear, and both models share the same overall size family, so the real choice often comes down to confirming whether your van uses a 15-inch or 16.5-inch wheel and whether you want bias-ply character or a radial-style alternative where available. Before choosing a tire, verify your exact model, wheel diameter, and preferred construction.
Which Tire Size Is Right for Your 1978 Dodge Van
Eleven tire sizes are used across 1978 Dodge Van vehicles, and both the Compact Van and Tradesman Van share the same overall fitment range. The key decision is not just size, but also wheel diameter: some fitments use 15-inch wheels, while others use 16.5-inch wheels, and the 15-inch group includes both bias-ply and radial-style choices. Understanding that distinction before choosing a product saves time and helps match the tire to the van and wheel you actually have.

LR78-15 is an alphanumeric radial size, with the R marking radial construction and the 15 marking a 15-inch rim. LR78-15 is available from Firestone in a narrow whitewall style, and this offering uses a bias-look radial construction with a 1970-pound load rating at 32 psi. It appeals to owners who want a 15-inch radial-style tire that preserves a more period-looking sidewall presentation than a modern metric radial.
Year(s): 1978|Fit(s): Compact Van, Tradesman Van|Construction: Bias Ply|Rim: 16.5 in
950-16.5 is a numeric bias-ply size in which the leading number identifies the nominal section-width class and the 16.5 identifies rim diameter. 950-16.5 is available from STA in blackwall form through the Traxion and Super Transport lines, with load ratings up to 2780 pounds at 60 psi. It is aimed at 1978 Dodge Van applications running 16.5-inch wheels and needing a distinctly truck-oriented bias-ply tire.
Year(s): 1978|Fit(s): Compact Van, Tradesman Van|Construction: Bias Ply|Rim: 16.5 in
875-16.5 is a numeric bias-ply size, with the 16.5 indicating a 16.5-inch rim diameter. 875-16.5 is available from STA in blackwall form through the Traxion and Transport Highway lines. It is a 16.5-inch truck-style choice for owners who have confirmed this size on their 1978 Dodge Van and want to stay with a period-appropriate bias-ply commercial format.
Year(s): 1978|Fit(s): Compact Van, Tradesman Van|Construction: Bias Ply|Rim: 16.5 in
800-16.5 is a numeric bias-ply size, with the first number denoting nominal section-width class and the 16.5 denoting rim diameter. 800-16.5 is available from STA in blackwall form through the Super Transport and Traxion lines, with load ratings up to 2045 pounds at 60 psi on some products. It is best suited to 1978 Dodge Van applications already using 16.5-inch wheels and seeking a straightforward commercial-style bias-ply replacement.
Year(s): 1978|Fit(s): Compact Van, Tradesman Van|Construction: Radial|Rim: 16.5-in rim
8.75R16.5 is a radial size in which 8.75 identifies nominal section width and R16.5 identifies radial construction on a 16.5-inch rim. This size is used on both 1978 Dodge Van models. It is the radial-format option for vans equipped with 16.5-inch wheels, so the first step is confirming that wheel diameter before comparing products in neighboring numeric truck sizes.
Two 1978 Dodge Van model lines are covered here. Both share the same overall range of tire sizes, so fitment starts with identifying the wheel diameter and the exact size on the van rather than choosing between model-exclusive tire options. Select a model below to narrow the fitment history and products to your specific van.
1978 Dodge Van Compact Van
The 1978 Dodge Van Compact Van gave buyers a smaller-format Dodge van with the straight-sided, practical packaging that made late-1970s vans useful for both light commercial work and personal use. Its tire fitments span both 15-inch and 16.5-inch wheel diameters, so the wheel on the van matters more than the model name alone when narrowing the right tire.
The 1978 Dodge Van Tradesman Van was Dodge's familiar full-size working van, known for cargo capacity, fleet service, and a strong place in custom-van culture. Like the Compact Van, it appears with both 15-inch and 16.5-inch wheel fitments, which means verifying the actual wheel and sidewall size is essential before settling on a replacement tire.
Twenty products are available across 11 tire sizes for 1978 Dodge Van vehicles. G78-15, H78-15, and L78-15 span Coker Classic, STA, BFGoodrich, Firestone, bias-ply or radial-style construction, and blackwall to whitewall sidewall treatments, while the 16.5-inch truck sizes center on STA blackwall bias-ply offerings. Confirm wheel diameter and construction preference before selecting.
These FAQs help sort out the unusually broad 1978 Dodge Van tire range, including 15-inch versus 16.5-inch fitments, bias-ply versus radial-style choices, sidewall appearance options, and the storage and inspection habits that matter on a collector or low-use van.
Size Basics & Fitment
What tire sizes fit 1978 Dodge Van vehicles?
1978 Dodge Van vehicles use 11 sizes across the Compact Van and Tradesman Van: E78-15, F78-15, G78-15, H78-15, HR78-15, L78-15, LR78-15, 800-16.5, 875-16.5, 950-16.5, and 8.75R16.5. Both models share that same overall size family. The 15-inch group includes alphanumeric bias-ply and radial-style sizes, while the 16.5-inch group includes numeric bias-ply truck sizes and one radial-format 8.75R16.5 application.
That means the first fitment check on a 1978 Dodge Van is wheel diameter, not simply model name. If your van has a 15-inch wheel, your choices stay within the E-, F-, G-, H-, HR-, L-, and LR-series family. If it has a 16.5-inch wheel, the correct path is the 800-, 875-, 950-, or 8.75R16.5 range. Once wheel diameter is confirmed, compare construction type, sidewall style, and load capability within that size family.
What does G78-15 mean on a 1978 Dodge Van tire?
G78-15 is an alphanumeric bias-ply tire size. The G is the historical size-series designation, the absence of an R indicates bias-ply construction, and the 15 means the tire mounts on a 15-inch wheel. On a 1978 Dodge Van, that places G78-15 in the traditional late-1960s and 1970s American sizing system rather than a modern metric format.
For a buyer, G78-15 is less about a modern dimensional formula and more about matching the vintage size language the van originally used. It also helps explain why sidewall appearance can vary so much within the same size, from blackwall truck-style offerings to wide whitewall passenger-style tires. If your sidewall reads G78-15, stay with that size unless you are intentionally making a broader fitment change with wheel and clearance checks.
What does 950-16.5 mean on a 1978 Dodge Van tire?
950-16.5 is a numeric bias-ply truck size. The 950 identifies the nominal section-width class in the older numeric system, and 16.5 is the wheel diameter in inches. On a 1978 Dodge Van, that immediately separates it from the 15-inch alphanumeric sizes and places it in the heavier-duty 16.5-inch commercial-style group.
The practical point is that a 950-16.5 tire cannot be treated as interchangeable with a 15-inch van tire, even if the vehicle model is the same. A 16.5-inch wheel requires a 16.5-inch tire, and commercial-style van applications often use different load and tread priorities than dressier 15-inch fitments. If your van wears 950-16.5, check the wheel diameter stamping and compare the load rating and rim-width range before moving to another 16.5-inch option.
Buying the Right Tire
Should I choose the L78-15 or the LR78-15 for my 1978 Dodge Van?
L78-15 and LR78-15 both fit 15-inch wheels on a 1978 Dodge Van, but they represent different construction approaches. L78-15 is a bias-ply size with blackwall, narrow whitewall, and wide whitewall options from Coker Classic and BFGoodrich. LR78-15 is a radial-format choice offered as a Firestone bias-look radial with a narrow whitewall, giving it a more period-minded appearance than a modern metric radial.
Choose L78-15 if your goal is to stay closer to the original late-1970s bias-ply feel and appearance. Choose LR78-15 if you want a radial-format tire while keeping a vintage sidewall presentation. The key is to decide whether your priority is historical construction authenticity or a radial-style driving experience, then confirm that the rest of your wheel and suspension setup still matches the size already on the van.
What sidewall styles are available for 1978 Dodge Van tires?
1978 Dodge Van tires span several sidewall looks depending on size. G78-15 and H78-15 are available in both wide whitewall and blackwall form, L78-15 adds blackwall, narrow whitewall, and wide whitewall choices, and LR78-15 appears as a narrow whitewall. The 16.5-inch truck sizes such as 800-16.5, 875-16.5, and 950-16.5 are blackwall offerings, reflecting their commercial-duty character.
That range matters because sidewall treatment changes the van's overall look almost as much as the wheel itself. Blackwalls usually suit fleet, work-van, and truck-style restorations, while whitewalls lean toward personalized vans or period passenger-style presentation. If authenticity matters for shows, compare your sidewall choice to period photos, factory literature, and marque-specific guidance for the exact way your 1978 Dodge Van was equipped and presented.
What brands make tires for 1978 Dodge Van vehicles?
1978 Dodge Van fitments are covered by Coker Classic, STA, BFGoodrich, and Firestone. Coker Classic appears in G78-15, H78-15, and L78-15 bias-ply applications, BFGoodrich also covers L78-15, Firestone covers LR78-15 in a bias-look radial, and STA handles G78-15, H78-15, and the 16.5-inch truck sizes such as 800-16.5, 875-16.5, and 950-16.5.
Brand choice on a 1978 Dodge Van is often tied to the style of the van and how you use it. A custom or passenger-oriented build may point you toward whitewall offerings in the 15-inch family, while a work-oriented van with 16.5-inch wheels often stays in the STA truck-style group. Once you know your size, compare sidewall appearance, load rating, and rim-width compatibility rather than choosing by brand name alone.
Fitting & Setup
What rim width do 1978 Dodge Van tires require?
Several 1978 Dodge Van sizes include clear rim-width ranges. G78-15 fits 5.00 to 7.00-inch rims, H78-15 fits 5.50 to 7.00-inch rims, L78-15 and LR78-15 fit 5.50 to 8.00-inch rims, 800-16.5 fits 6.00 to 6.50-inch rims, and 950-16.5 fits 6.50 to 6.75-inch rims. Those ranges are specific to each size and should not be transferred from one tire size to another.
Rim width is one of the most overlooked checks on a vintage van, especially when an old custom or fleet vehicle has been changed over the years. Before replacing tires on a 1978 Dodge Van, verify both the wheel diameter and the wheel width so the tire is supported correctly. If your van carries a size without a published rim-width range in front of you, match the exact sidewall size first and compare only within that same size family.
Do 1978 Dodge Van tires require inner tubes?
Inner-tube status is not universal across the 1978 Dodge Van range. The available 15-inch and 16.5-inch products here do not carry tube-type or tubeless markings in the size descriptions, so tube requirements can vary by the exact tire design and by the wheel itself. That matters most on older wheels, split applications, or wheels with condition issues that affect air retention.
The safest approach is to inspect the actual wheel and confirm the sidewall marking on the exact tire you intend to use. If a 1978 Dodge Van still has original or older service wheels, corrosion, pitting, or previous repairs can influence whether a tubeless setup is practical. A tube should never be assumed or omitted casually; match it to the wheel condition and the exact tire's construction and sidewall instructions.
Can the original 1978 Dodge Van wheels be used with all tire sizes?
Original 1978 Dodge Van wheels can only be reused when the wheel diameter matches the tire size family already on the van. A 15-inch wheel can accept the 15-inch sizes such as G78-15, H78-15, L78-15, and LR78-15 if the rim width is also suitable, while a 16.5-inch wheel is reserved for sizes such as 800-16.5, 875-16.5, 950-16.5, or 8.75R16.5. Wheel diameter is not interchangeable between 15 and 16.5 inches.
That distinction is especially important on older vans because wheel swaps over the decades are common. If you are unsure what your 1978 Dodge Van has, measure the wheel or confirm the stamping before selecting a tire. After diameter is confirmed, compare the rim-width range for the exact size you want. That extra step prevents the common mistake of buying the right-looking sidewall in the wrong wheel diameter.
Maintenance, Storage & Longevity
How should I store a 1978 Dodge Van when the tires are fitted?
A stored 1978 Dodge Van should be kept out of direct sunlight and away from ozone sources such as electric motors, welders, generators, and air compressors. Clean, dry flooring helps, and tire pressure should be maintained even during storage. Bias-ply tires can flat-spot more readily during long static periods, so vans running bias-ply construction especially benefit from periodic movement or being supported in a way that reduces sustained loading.
Because a van is heavier than many collector cars, storage habits matter even more. Roll the van occasionally if practical, inspect the sidewalls for early cracking, and avoid parking on damp soil or oily surfaces. If the vehicle will sit for a long season, some owners use stands to reduce tire load, but the suspension should still be supported properly. A little storage discipline preserves both the casing and the way the van feels on the road.
How long do tires on a 1978 Dodge Van typically last?
Tires on a 1978 Dodge Van should be judged more by age and condition than by mileage. A collector or occasional-use van may wear very little tread, yet the rubber can still harden, crack, or weaken over time. As a practical rule, tires deserve close evaluation by about five to seven years of age, and replacement becomes a serious consideration as they approach ten years, using the DOT date code and overall condition as guides.
That age-based approach is especially important for a heavy vintage van, because stored weight and long idle periods are harder on tires than many owners realize. Even if a 1978 Dodge Van only attends shows or takes occasional weekend drives, old tires can lose flexibility and confidence long before the tread is gone. If age and condition point in different directions, let the older factor win and plan replacement conservatively.
How often should tires on a 1978 Dodge Van be inspected?
Tires on a 1978 Dodge Van should be inspected before every drive and again before any longer trip. Check for sidewall cracking, cuts, bulges, uneven wear, and slow pressure loss, and look closely at the valve stems as well. On a van that spends long stretches parked, these checks matter because age and storage can affect the tire even when mileage stays low.
A quick walk-around catches many problems before they become roadside trouble. Older vans place substantial load on their tires, and a pressure issue or sidewall defect becomes more serious at highway speed or with cargo aboard. Make inspection part of the same routine as checking lights, fluids, and brakes. If one tire on a 1978 Dodge Van looks noticeably different from the others, stop and investigate before the next outing.
Restoration & Authenticity
What tires were originally fitted to the 1978 Dodge Van Compact Van?
A 1978 Dodge Van Compact Van would have been associated first and foremost with period-correct late-1970s sizing systems such as alphanumeric bias-ply tires, and some applications also moved into radial-format offerings during that era. The size range for 1978 Dodge Van includes both bias-ply and radial-style fitments, depending on wheel diameter and application. Original-equipment brand should not be assumed from replacement tire availability alone.
For an accurate restoration, begin with the size shown on your van's original paperwork, surviving sidewall information, or wheel-and-tire combination if it is believed original. After that, compare whether your project calls for a blackwall, narrow whitewall, or wider whitewall appearance. If the van will be judged, a Dodge truck club, factory literature, or a marque specialist can help confirm whether your exact body style and market were more commonly seen with bias-ply or radial-type replacements.
Does correct tire fitment matter for showing a 1978 Dodge Van?
Correct tire fitment matters on a shown 1978 Dodge Van because judges and knowledgeable enthusiasts notice more than just whether the tire physically fits the wheel. Size family, construction type, wheel diameter, sidewall style, and overall stance all affect how authentic the van appears. A modern-looking mismatch, or a truck-style blackwall where a dressier presentation is expected, can change the visual impression immediately.
That does not mean every show expects the same standard, but it does mean tire choice should be intentional. A restored custom van, a fleet-style Tradesman, and a highly original survivor may each call for a different sidewall and construction approach even within the same 1978 Dodge Van range. Before a judged event, compare your selection against period photos and the event's own authenticity standards so the tires support the story your van is telling.
What is the difference between STA Traxion and STA Super Transport for the 1978 Dodge Van?
On a 1978 Dodge Van, STA Traxion and STA Super Transport overlap in the 950-16.5 size, and both carry a 2780-pound load rating at 60 psi. Their weights differ slightly, with Traxion at 40 pounds and Super Transport at 41 pounds, and both fit 6.50 to 6.75-inch rims. Both are blackwall bias-ply truck tires, but they sit in different STA series families aimed at commercial-style use.
That means the choice is less about basic fitment and more about the tread family and the overall character you want on the van. If your 1978 Dodge Van is being restored with a stronger work-van or truck-service personality, either can make sense within the same size and load class. Once the wheel and load requirement are confirmed, compare the series details and visual character instead of assuming every 950-16.5 tire feels or presents exactly the same.
Safety & Road Use
Are 1978 Dodge Van tires safe for highway driving?
1978 Dodge Van tires can be suitable for highway driving when the correct size, wheel diameter, inflation, and load capacity are matched properly to the van. The sizes here are primarily bias-ply and radial-style vintage or commercial tires, and none of the available products in view carry a visible modern speed-rating letter such as S, T, or H in the size designation. On a 1978 van, the tire is only one part of the highway-safety picture alongside brakes, steering, suspension, wheel condition, and alignment.
The practical takeaway is to drive within the vehicle's overall limits, not just the tire's general category. A well-sorted 1978 Dodge Van with fresh, properly matched tires is a very different road machine than one on aged rubber with unknown wheel history. Before regular highway use, confirm load suitability, inspect every tire closely, and make sure the van's mechanical systems are ready for sustained speed and heat, especially if it has spent long periods off the road.
What inflation pressure should I use for 1978 Dodge Van tires?
Inflation pressure on a 1978 Dodge Van depends on the exact tire size and product. G78-15 products reach 1620 pounds at 32 psi, H78-15 products reach 1770 pounds at 32 psi or 1830 pounds at 45 psi depending on the tire, L78-15 and LR78-15 reach 1970 pounds at 32 psi, 800-16.5 reaches 2045 pounds at 60 psi, and 950-16.5 reaches 2780 pounds at 60 psi. Those figures belong to their specific tires and should not be swapped across sizes.
Use the van's original inflation recommendation as the starting point for operating pressure, then compare it with the tire maker's load-and-pressure guidance for the exact reproduction or vintage-style tire you choose. A lightly loaded van and a work-equipped van may need different real-world pressures even within the same size. The main rule is consistency: match the pressure to the exact tire and the actual service load instead of using a one-pressure-fits-all shortcut.
What should I check before taking a 1978 Dodge Van on a longer drive?
Before a longer drive in a 1978 Dodge Van, inspect every tire for cracking, cuts, bulges, irregular wear, and proper cold pressure, and do not forget the spare. Check valve stems carefully, especially on older wheels and long-stored vehicles, and make sure the tire size and wheel diameter still match at all four corners. Because these vans are often restored, customized, or long-stored, tire age is just as important as tread depth.
A tire check should sit inside a broader pre-trip inspection that includes brakes, steering play, wheel bearings, fluid levels, and lighting. Vintage vans can look ready while still hiding age-related weaknesses, so a cautious once-over pays dividends. If your 1978 Dodge Van carries mixed construction types, mixed ages, or a recent wheel change, sort that out before committing to distance. The safest long drive usually begins in the garage, not on the highway shoulder.
