1980 Plymouth Vans Tire Fitment Guide

1980 Plymouth Vans uses seven tire sizes across three model lines. PB100 uses 195/75R15, 205/75R15, 225/75R15, and 235/75R15, while PB200 uses 225/75R15 and 235/75R15. PB300 uses 8.00R16.5, 800-16.5, and 875-16.5, which immediately separates it from the lighter vans because it runs on 16.5-inch wheels instead of 15-inch wheels.

The practical takeaway is that year and make alone are not enough on a 1980 Plymouth Vans search. If you own a PB100 or PB200, you are looking at 15-inch radial fitments with several whitewall-style choices. If you own a PB300, you need to stay focused on 16.5-inch heavy-duty sizing, where the decision may also involve choosing between radial and bias-ply construction depending on how you want the van to look and drive.

On a 1980 Plymouth Vans tire, 195/75R15 is a metric radial size. The 195 is the nominal section width in millimeters, 75 is the aspect ratio, R means radial construction, and 15 is the wheel diameter in inches. On this year and make, that size belongs to the PB100 and mounts on 15-inch wheels, with products built around rim widths from 5 to 7 inches.

That code matters because it tells you more than just diameter. A 195/75R15 keeps you in the passenger-type 15-inch radial family used on lighter-duty PB100 vans, and it also narrows your product choices to whitewall-style tires rather than truck blackwalls. If your van currently wears a different metric size on a 15-inch wheel, compare the exact sidewall marking and wheel before deciding whether you are preserving an existing fitment or changing to another PB100-compatible option.

On a 1980 Plymouth Vans tire, 800-16.5 is an older numeric bias-ply truck size. The 800 designates the nominal section width in the traditional inch-based naming system, the dash format identifies it as bias-ply rather than radial, and 16.5 is the wheel diameter in inches. For 1980 Plymouth Vans, that size is used on the PB300 and appears in STA blackwall truck tires.

This code is easy to confuse with 8.00R16.5, but the construction marking makes a real difference. The radial version includes an R, while 800-16.5 remains bias-ply. If your PB300 is a work-oriented van or restoration that needs the look and feel of an older truck tire, the numeric size points you in that direction. Before ordering, confirm the exact sidewall marking on the van and make sure the wheel is in fact a 16.5-inch rim, not a 15-inch or 16-inch wheel.

For a 1980 Plymouth Vans PB300, the difference between 8.00R16.5 and 800-16.5 is primarily construction. 8.00R16.5 is a radial truck size, while 800-16.5 is a bias-ply truck size, and both fit 16.5-inch PB300 wheels rather than the 15-inch wheels used on PB100 and PB200. The radial route is the modernized construction choice within the PB300 range, while the numeric bias-ply size stays closer to older truck-tire practice.

Choose the radial 8.00R16.5 if your goal is a PB300 with a more contemporary radial driving character. Choose 800-16.5 if you want the traditional heavy-duty bias-ply appearance and period-style construction often associated with older commercial vehicles. The best starting point is the tire already on the van or the factory wheel and service information for your specific PB300, since the two sizes should not be treated as interchangeable just because they share a 16.5-inch rim diameter.

1980 Plymouth Vans tires span a wide sidewall-style range depending on size and model. The 15-inch radial sizes use narrow whitewall, wide whitewall, goldline, and RWL treatments, while the 16.5-inch PB300 truck sizes are blackwall only in the available bias-ply products. Within the 15-inch group, 195/75R15 appears in narrow and wide whitewall, 205/75R15 adds goldline, 225/75R15 stays with narrow and wide whitewall, and 235/75R15 reaches from whitewalls to raised white letters.

That variety lets you tune the van’s visual character to match its role. A whitewall or goldline can suit a passenger-oriented or conversion-style PB100 or PB200, while blackwall truck tires make more visual sense on a heavier PB300. If originality matters, sidewall presentation can influence how correct the van looks even when the size itself is right. It helps to decide whether you want a commercial appearance, a period custom van feel, or a cleaner factory-style passenger presentation before narrowing down the exact product.

1980 Plymouth Vans tires are available from several brands, and the brand mix changes by size. The 15-inch radial sizes are covered by Coker Classic, American Classic, BFGoodrich, Tornel, and Maxxis depending on the exact measurement, while the 16.5-inch bias-ply PB300 sizes are covered by STA. The broadest mix appears in 235/75R15, where BFGoodrich, American Classic, Maxxis, and Coker Classic all have options.

Brand choice matters because it often tracks with sidewall style and tire character more than with basic fit. Some 15-inch sizes lean toward whitewall styling for a more vintage passenger-van look, while BFGoodrich also brings an RWL all-terrain flavor in 235/75R15. On PB300, STA’s truck-oriented offerings keep the focus on blackwall commercial-duty presentation. Once you know your exact size, compare brands by construction, sidewall treatment, rim-width compatibility, and load information rather than choosing by name alone.

Rim-width requirements vary by tire size on 1980 Plymouth Vans. For 195/75R15, the range runs from 5 to 7 inches; 205/75R15 fits 5.50 to 7.50-inch rims; 225/75R15 works across 6.00 to 8.00 inches, with some products capping at 7.5 inches; and 235/75R15 spans roughly 6.0 to 8.5 inches depending on the tire. On PB300, 800-16.5 fits 6.00 to 6.50-inch rims in the products that carry rim-width guidance.

That means matching the wheel to the tire is just as important as matching the tire to the van. Two tires with the same overall size code can still prefer slightly different wheel widths depending on brand and series. Before committing to a tire, measure the actual wheel or confirm its stamped width. That is especially important on older vans that may have had wheels swapped over the years, since a non-original wheel can affect sidewall shape and how correctly the tire seats and carries load.

The available 15-inch and 16.5-inch products for 1980 Plymouth Vans do not carry tube-type or tubeless markings in their size descriptions here, so tube use should be confirmed by the tire’s actual sidewall marking and by the wheel design. The PB100 and PB200 tires are modern radial-type passenger and light-truck sizes, while PB300 includes heavy-duty truck sizes in both radial and bias-ply formats, which makes wheel condition and application especially important.

The safest approach is to inspect the wheels before choosing tubes or running without them. Original van wheels, especially on a working PB300, may have been repaired, rusted, or changed over time, and that can matter as much as the tire itself. If you are restoring the van, check the exact tire specification and the wheel’s intended use rather than assuming all older-looking tires need tubes or all radial tires run tubeless. A marque specialist or experienced truck-tire installer can help with final setup.

Original 1980 Plymouth Vans wheels can only be shared within the size family that matches the model’s wheel diameter. PB100 and PB200 use 15-inch tires, so those wheels relate to 195/75R15, 205/75R15, 225/75R15, and 235/75R15 depending on the model. PB300 uses 16.5-inch tires, so its wheels relate to 8.00R16.5, 800-16.5, and 875-16.5 instead.

The important point is that a common year and make does not create cross-compatibility between PB100, PB200, and PB300 wheels. Even when two tires share a wheel diameter, rim width still needs to be checked against the chosen tire. A PB100 or PB200 owner may be able to move among several 15-inch size options if the wheel width supports them, but a PB300 owner should stay within the 16.5-inch group and confirm that the wheel matches the exact tire’s width requirements and intended service.

A stored 1980 Plymouth Vans should be kept out of direct sunlight and away from ozone-producing sources such as electric motors, battery chargers, and welders. Clean, dry concrete is better than damp ground, and maintaining proper inflation helps preserve the tire shape during inactivity. If the van sits for long stretches, moving it periodically or supporting it correctly can reduce flat-spotting, which is especially relevant for heavier vehicles and older-style constructions.

Storage strategy should match how the van is used. A PB100 or PB200 with 15-inch radials still benefits from occasional movement, but a PB300 with heavy-duty truck tires deserves extra attention because weight and long idle periods can be harder on the casing. If the van is part of a collection, wash off road film before storage and cover the tires from light exposure. Long-term appearance and service life usually improve more from stable storage conditions than from low mileage alone.

Tire life on a 1980 Plymouth Vans is usually judged more by age than by miles, especially on collector, hobby, or occasional-use vans. A sensible rule is to begin evaluating tires closely at around five to seven years and to give serious replacement consideration by about ten years, regardless of remaining tread. The DOT date code on the sidewall is the quickest way to establish age when the van has changed owners or sat unused.

That age-based approach matters because an older van can wear tires very slowly while the rubber still hardens and the casing still degrades over time. A PB300 that sees load duty may age tires differently than a lightly used PB100 conversion van, but neither should be judged by tread depth alone. If the van is new to you, check every tire including the spare so you are not mixing very old rubber into regular use without realizing it.

Tires on a 1980 Plymouth Vans should be inspected before every drive and again before any extended trip. Look for sidewall cracking, cuts, bulges, irregular wear, embedded debris, and pressure loss, and pay attention to how the van feels rolling away from a stop. On a heavier van like a PB300, visual inspection is especially important because truck-type tires may spend long periods carrying load even when the vehicle is parked.

A quick walkaround catches most of the issues that strand older vans. Check all four road tires and the spare, and do not overlook valve stems when the tires are being serviced or aired up. If the van has been stored, inspect the tread blocks and sidewalls before the first drive rather than assuming the tires are fine because they still hold air. Regular checks also help reveal alignment or suspension issues before they create uneven wear across an expensive set.

A 1980 Plymouth Vans PB100 belongs to a period when radial tires were well established on American passenger vehicles and light-duty vans, and every PB100 fitment here is a 15-inch radial size. Depending on the exact van, that means 195/75R15, 205/75R15, 225/75R15, or 235/75R15 rather than the 16.5-inch truck sizes used on PB300. Sidewall appearance could still vary with trim, market, and how the van was ordered, so a period-correct look is not determined by size alone.

For a restoration, the most important first step is confirming the exact model and the tire size the van was equipped with before cosmetic choices enter the picture. Whitewall width and sidewall treatment can shape the finished look of a passenger-oriented or custom-style PB100 even when the underlying fitment is right. If you are chasing a highly authentic presentation, compare original photos, window-sticker information if available, and marque-club guidance before finalizing the sidewall style.

Correct tire fitment absolutely matters when showing a 1980 Plymouth Vans because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style immediately. A PB100 or PB200 wearing the wrong 15-inch metric size, or a PB300 wearing a passenger-style tire instead of a heavy-duty 16.5-inch truck fitment, can look out of character even before close inspection. On more originality-focused judging, sidewall treatment can matter nearly as much as the size itself.

The right choice depends on the type of event. A factory-stock restoration usually benefits from staying close to the original size family and era-appropriate sidewall presentation, while a period custom van may justify a different visual treatment that still feels authentic to the time. Before a serious show, confirm whether the event rewards strict factory accuracy or broader period correctness. Marque clubs and event rulebooks are often the best final word if your van falls into a borderline custom or commercial category.

For a 1980 Plymouth Vans PB300 in 800-16.5, STA Super Transport and STA Traxion share the same size, blackwall appearance, and bias-ply construction, but they are different tire series with different weight and load details. Super Transport carries a 2,045-pound load figure at 60 psi and weighs 33 pounds, while Traxion weighs 31 pounds in the same size. In 875-16.5, Traxion is also available alongside STA Transport Highway, giving PB300 owners more than one heavy-duty series in the larger numeric size.

That means the choice is less about basic fit and more about the type of truck-tire character you want within the PB300’s 16.5-inch bias-ply family. If your priority is a traditional commercial-van look with a clearly stated load figure in 800-16.5, Super Transport may appeal. If you are comparing series across the PB300 range, weigh the exact size, intended use, and any rim-width guidance that applies to your wheel before settling on one of the STA options.

1980 Plymouth Vans tires can be suitable for highway use when the exact tire, model, condition, and load demands are all matched correctly. The clearest speed information appears in 235/75R15, where BFGoodrich offers an S-rated tire with a 112 mph ceiling, and the other 15-inch radial sizes are modern radial constructions commonly used on road-driven vintage vehicles. PB300’s 16.5-inch choices include both radial and bias-ply truck tires, which should be treated according to their specific sidewall markings and intended use.

On a vehicle from 1980, tire capability is only one part of highway readiness. Brakes, steering, suspension, wheel condition, and how the van is loaded often matter just as much as the tire itself, especially on a work-oriented PB300. If your van is mechanically sound and the tires are in good condition, properly inflated, and correctly matched to the wheels, normal highway travel is realistic. Long-distance or higher-speed use deserves an especially careful inspection before departure.

Inflation pressure on 1980 Plymouth Vans depends on the exact tire size and product, not just the van itself. Examples include 195/75R15 at 32 to 35 psi depending on product, 205/75R15 at 35 psi in several options, 225/75R15 at 32 or 35 psi depending on brand, 235/75R15 at 32, 35, or 50 psi depending on the specific tire, and 800-16.5 at 60 psi in the STA Super Transport. Those figures are tied to the individual tire’s published load capacity and should not be transferred from one size to another.

The best practice is to start with the original Plymouth guidance for the van and then compare it with the tire manufacturer’s pressure and load information for the exact reproduction or replacement tire you are using. A whitewall passenger-style 15-inch radial and a truck-oriented 235/75R15 do not necessarily want the same pressure, even though both fit 15-inch wheels. On PB300, pressure choice becomes even more sensitive because load-carrying duty can change the correct setting significantly.

Before a longer drive in a 1980 Plymouth Vans, inspect each tire for cracking, cuts, bulges, uneven wear, and proper inflation, then check the spare as carefully as the road tires. Verify that the sidewall size on the van matches the wheel diameter you expect, especially if you own a PB300 with 16.5-inch wheels or recently acquired the vehicle. A van that has sat for a while also deserves a close look at valve stems and any signs of slow leakage.

Tires are only one part of longer-trip readiness on an older van, but they are one of the easiest places to prevent problems before you leave. Pair the tire inspection with a broader check of brakes, wheel bearings, steering play, fluids, belts, and lights. If the van carries cargo or passengers, think about load before departure rather than after packing. A properly matched tire in good condition is far more reassuring on a long trip than a low-mileage tire whose age and condition are still a question.
