The 1980 Plymouth Vans PB300 sits in the era when full-size American vans were expected to handle real passenger, cargo, and work duty, often in long-wheelbase and higher-GVWR configurations. That makes tire selection on this model less about style alone and more about matching the van’s exact load-oriented setup. The 1980 Plymouth Vans PB300 uses 16.5-inch fitments in 8.00R16.5 radial, 800-16.5 bias-ply, or 875-16.5 bias-ply form, depending on the specific Voyager or Voyager Maxi configuration. Available choices stay true to the truck-van character with blackwall STA offerings across several series. The right decision starts with the exact sub-model, front-axle rating, and GVWR before comparing construction and tread style.
Which Tire Size Is Right for The 1980 Plymouth Vans PB300
Three primary tire sizes apply to the 1980 Plymouth Vans PB300, and the correct choice depends on the exact Voyager or Voyager Maxi configuration. All use a 16.5-inch rim, but fitment varies by sub-model and GVWR, so the first step is confirming the van’s specific setup before deciding between radial and bias-ply construction or comparing available tire series.
8.00R16.5 uses a vintage numeric radial format in which the 8.00 figure indicates nominal section width, the R marks radial construction, and 16.5 is the rim diameter in inches. On the 1980 Plymouth Vans PB300, this is a radial-style fitment used on certain sub-models rather than a universal size across the range. It is especially relevant for owners who want a radial construction while staying with the van’s 16.5-inch wheel diameter. Before choosing it, confirm that your exact Voyager or Voyager Maxi configuration is one of the PB300 versions that uses this size.
800-16.5 is a numeric bias-ply size where 800 represents an approximate 8.00-inch nominal section width and 16.5 identifies the wheel diameter. For the 1980 Plymouth Vans PB300, it is one of the load-oriented bias-ply fitments used on selected configurations, giving the van a distinctly traditional truck-tire presentation. Available products in this size come from STA in the Super Transport and Traxion series, both with blackwall sidewalls and Military & Truck positioning. This size makes the most sense when your PB300 configuration calls for it and you want to retain a period-style bias-ply construction.
875-16.5 is another numeric bias-ply truck size, with the 875 designation indicating a wider nominal section than 800-16.5 and the same 16.5-inch rim diameter. On the 1980 Plymouth Vans PB300, this size appears across more than one Voyager and Voyager Maxi configuration, including the higher-GVWR versions that rely on it exclusively. STA offers blackwall choices in this size through the Traxion and Transport Highway series, giving owners a choice in tire character while staying within the correct fitment family. It is the size to evaluate carefully when matching a heavier-duty PB300 setup.
Sub-model fitment on the 1980 Plymouth Vans PB300 is not one-size-fits-all. Tire choice depends on whether the van is a Voyager or Voyager Maxi, along with its front-axle rating and GVWR, because some versions allow multiple fitments while the 7800 GVWR models use only 875-16.5.
This PB300 Voyager configuration can use 8.00R16.5 radial, 800-16.5 bias-ply, or 875-16.5 bias-ply tires on 16.5-inch wheels. That gives the owner a broader construction and sizing decision, so the next step is matching the van’s current wheel setup and intended use before selecting a tire.
This higher-GVWR Voyager uses 875-16.5 bias-ply tires. Tire selection here is more straightforward, with the main comparison centered on the available STA series and verifying that the van still retains the correct 16.5-inch wheel and heavy-duty fitment setup.
This Voyager version shares the broader three-size fitment pattern of 8.00R16.5 radial, 800-16.5 bias-ply, and 875-16.5 bias-ply. Choosing among them calls for a closer look at construction preference, wheel compatibility, and whether the van is being kept in a traditional bias-ply configuration or evaluated for radial use.
This 7800 GVWR Voyager uses 875-16.5 bias-ply tires only. That narrows the fitment question to selecting the right product within that size and making sure the current wheels, suspension condition, and overall van setup still match the original heavy-duty tire requirement.
This Voyager Maxi configuration can use 8.00R16.5 radial, 800-16.5 bias-ply, or 875-16.5 bias-ply tires. Because more than one primary size applies, the buyer should confirm the actual wheel and tire combination on the van before narrowing the choice to a specific series or construction.
This higher-capacity Voyager Maxi uses 875-16.5 bias-ply tires. Selection is mainly about choosing between the available blackwall STA options while keeping the van’s 16.5-inch wheel diameter and heavier-duty load-focused configuration in mind.
This PB300 Voyager Maxi setup also accepts 8.00R16.5 radial, 800-16.5 bias-ply, and 875-16.5 bias-ply fitments. The practical decision is determining which size the van is set up to use now, then choosing the construction and tread style that best suits restoration goals or regular road use.
This 7800 GVWR Voyager Maxi uses 875-16.5 bias-ply tires. Owners of this version can focus on comparing the available series in the correct size rather than sorting through multiple primary fitments, while still confirming wheel condition and overall clearance before use.
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.

Common 1980 Plymouth Vans PB300 tire questions usually center on sub-model-specific sizing, 16.5-inch rim fitment, bias-ply versus radial choices, and what to inspect before putting a full-size vintage van back on the road.
Tire Size & Fitment
What tire size fits a 1980 Plymouth Vans PB300?
The 1980 Plymouth Vans PB300 uses three primary tire sizes across the model range: 8.00R16.5 radial, 800-16.5 bias-ply, and 875-16.5 bias-ply. All three are 16.5-inch fitments, but they do not apply to every PB300 in the same way because Voyager and Voyager Maxi versions differ by front-axle rating and GVWR.
The practical step is to identify the exact sub-model before choosing a tire. Several 7200 GVWR versions can use more than one size, while the 7800 GVWR configurations use 875-16.5 only. That distinction matters more than the van’s trim name alone, especially if the vehicle has changed wheels or has been in commercial service before restoration.
What size rim does a 1980 Plymouth Vans PB300 use?
The tire fitments used on the 1980 Plymouth Vans PB300 are built around a 16.5-inch rim diameter. That applies whether the van is using 8.00R16.5 radial, 800-16.5 bias-ply, or 875-16.5 bias-ply tires, so wheel diameter remains consistent even though the actual tire size may vary by configuration.
Rim diameter is only the first checkpoint on a van like this. Wheel width, current wheel type, and any past changes to axle or suspension components can still affect which tire is appropriate. A PB300 that no longer has its original-style wheels should be measured carefully before mounting a new set, especially when comparing 800-16.5 and 875-16.5 fitments.
Why does the 1980 Plymouth Vans PB300 have more than one tire size?
The 1980 Plymouth Vans PB300 spans multiple Voyager and Voyager Maxi configurations, and those versions carry different front-axle ratings and GVWR designations. That is why the fitment range includes 8.00R16.5 radial, 800-16.5 bias-ply, and 875-16.5 bias-ply rather than one universal tire size for every van wearing the PB300 name.
That variation means the tire decision starts with the exact vehicle configuration, not just the model badge. Higher-GVWR 7800 versions use 875-16.5 only, while some 7200 GVWR versions allow multiple fitments. Checking the van’s wheel setup and service role helps prevent choosing a tire that matches the wheel diameter but not the intended heavy-duty application.
Choosing the Right Tire
What should I consider when choosing a 1980 Plymouth Vans PB300 tire?
Start with the exact PB300 configuration, because tire size varies by sub-model, front-axle rating, and GVWR. After that, the main factors are correct size, 16.5-inch wheel compatibility, construction type, and whether the van is being kept in a traditional heavy-duty bias-ply setup or fitted with a radial-size option used on certain versions.
Product choice then becomes a question of tire series and intended use. On the available bias-ply sizes, STA options are geared toward Military & Truck use and carry different series names such as Super Transport, Traxion, and Transport Highway. Matching the tire to the van’s actual wheel dimensions and working role is more important than choosing by appearance alone.
What brands offer tires for the 1980 Plymouth Vans PB300?
The available products for the 1980 Plymouth Vans PB300 come from STA. That includes 800-16.5 and 875-16.5 bias-ply offerings in truck-oriented series, all built around the PB300’s 16.5-inch wheel fitment and presented with blackwall sidewalls rather than decorative passenger-car treatments.
Since the current selection is centered on one brand, comparison is less about brand preference and more about choosing the right size and series for the van. A buyer should focus on whether the PB300 needs 800-16.5 or 875-16.5, then compare the available tire’s rim-width specification, construction, and overall suitability for a full-size van’s weight and intended use.
What tire series are available for the 1980 Plymouth Vans PB300?
The 1980 Plymouth Vans PB300 has available products in the STA Super Transport, STA Traxion, and STA Transport Highway series. Those series appear in the bias-ply truck sizes used on this van, with 800-16.5 offered in Super Transport and Traxion, and 875-16.5 offered in Traxion and Transport Highway.
Series differences help organize the buying decision once the correct size is known. A PB300 owner should choose the tire size that matches the van’s configuration first, then compare series within that fitment for the kind of tread character and service presentation that suits the vehicle. On a work-oriented vintage van, the right series follows correct fitment rather than replacing it.
Restoration & Appearance
Which tire should I choose for a period-style 1980 Plymouth Vans PB300?
A period-style 1980 Plymouth Vans PB300 usually starts with the original fitment family for the exact sub-model, which means 800-16.5 or 875-16.5 bias-ply on the covered heavy-duty applications, or 8.00R16.5 where that radial fitment applies. The right starting point depends on whether the van is a Voyager or Voyager Maxi and on its GVWR classification.
For a restoration-oriented result, begin with the correct size and construction type before comparing tire series. Blackwall truck tires preserve the van’s commercial-duty look better than chasing a generic vintage appearance. If exact originality matters at a judged level, the final appearance details should be checked against marque references, historic photos, or vehicle-specific documentation.
Does correct tire fitment matter for a 1980 Plymouth Vans PB300 restoration?
Correct tire fitment matters on a 1980 Plymouth Vans PB300 because the van’s stance, working character, and load-oriented presentation are closely tied to size and construction. A 7200 GVWR van with multiple fitment possibilities should not be treated the same as a 7800 GVWR version that uses 875-16.5 bias-ply only.
Restoration decisions should preserve both appearance and configuration logic. Keeping the right 16.5-inch fitment family helps the van look proportionate and avoids turning a heavy-duty full-size van into something that appears mismatched. It also makes product comparison more meaningful, since tread series and sidewall treatment only matter after the basic fitment has been chosen correctly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 Plymouth Vans PB300?
Yes, modifications can affect tire fitment on a 1980 Plymouth Vans PB300 even when the wheel still measures 16.5 inches. Aftermarket wheels, wheel-width changes, suspension work, altered ride height, or body modifications can change how an 800-16.5, 875-16.5, or 8.00R16.5 tire sits in the wheel opening and how it clears steering and suspension components.
A modified PB300 should be checked as an individual vehicle before a new tire is chosen. Tire size alone does not confirm compatibility once the original setup has changed. Measure the actual wheel, inspect clearance at full steering travel, and confirm that the van’s current use still matches the load-focused character of the tire being considered.
What should I inspect before driving a 1980 Plymouth Vans PB300 on new tires?
Before driving a 1980 Plymouth Vans PB300 on new tires, inspect the wheels for damage or corrosion, confirm the wheel diameter and width, and make sure the selected size matches the van’s exact configuration. The suspension, steering components, and brake hardware should also be checked so the tires are not asked to compensate for worn mechanical parts.
Tire condition still deserves a final walkaround after mounting. Look for proper inflation, valve-stem condition, bead seating, and any signs of rubbing once the van is on the ground. A short, careful road test helps confirm tracking and clearance, which is especially worthwhile on a vintage full-size van that may have spent long periods parked.
How should 800-16.5 or 875-16.5 tires on a collector 1980 Plymouth Vans PB300 be maintained?
Collector-use 800-16.5 or 875-16.5 tires on a 1980 Plymouth Vans PB300 should be kept properly inflated, inspected regularly for cuts, cracking, bulges, uneven wear, and slow air loss, and stored away from prolonged sunlight, heat, moisture, and ozone sources when the van is not being used often. Low annual mileage does not eliminate aging concerns.
A full-size van places real demands on its tires even during occasional use, so maintenance should include periodic pressure checks and visual inspection before each drive. It also helps to evaluate tread and sidewall condition after long storage periods. Any tire showing age-related deterioration or unexplained air loss deserves closer inspection before road use resumes.
