The 1981 Dodge Trucks W250 sits in the era when three-quarter-ton 4x4 pickups were expected to handle real work, rough roads, and heavy-duty service without losing their straightforward mechanical character. That matters when choosing tires, because this truck uses several 16.5-inch fitments across its GVWR and snow-package configurations, with both bias-ply and radial applications in the mix. Sizes such as 800-16.5, 875-16.5, 950-16.5, 8.00R16.5, and 9.50R16.5 each point toward a different setup and use case. The real decision starts with confirming the exact W250 sub-model, then choosing a tire series that matches the truck's load role, appearance goals, and wheel setup.
Which Tire Size Is Right for The 1981 Dodge Trucks W250
The 1981 Dodge Trucks W250 uses five primary tire sizes, and the correct one depends on the exact GVWR and whether the truck carries the Snow Package. All of these fitments use a 16.5-inch rim, but they vary by section width and by construction, with both bias-ply and radial applications appearing across the range. The first step is identifying the exact sub-model so the tire choice starts from the right size and construction.
The 800-16.5 designation is a numeric bias-ply truck size, with the leading number indicating an approximate 8.00-inch nominal section width and the final number identifying a 16.5-inch rim. On the 1981 Dodge Trucks W250, this size belongs to bias-ply fitments used on certain standard-GVWR, 7500-GVWR, and Snow Package versions. Available choices include STA Super Transport and STA Traxion, both in blackwall form and both aimed at military and truck use. This size is a practical place to start when the truck's sub-model calls for a traditional bias-ply setup on a 16.5-inch wheel.
The 875-16.5 code is another numeric bias-ply truck size, this time indicating an approximate 8.75-inch nominal section width on a 16.5-inch rim. For the 1981 Dodge Trucks W250, it appears on certain non-heavy-duty and 7500-GVWR configurations where a wider bias-ply tire than 800-16.5 is used. Product choices include STA Traxion and STA Transport Highway, both offered as blackwalls with truck-oriented construction and character. This size deserves a careful look when the truck needs the correct W250 fitment while still leaving room to choose between a more traction-focused or more highway-oriented series.
The 8.00R16.5 size uses a vintage-style radial designation, with 8.00 referring to nominal section width, R identifying radial construction, and 16.5 marking the rim diameter. On the 1981 Dodge Trucks W250, this is a radial fitment associated with the 7500-GVWR version rather than every W250 configuration. Its role is important because it changes the construction choice, not just the sizing convention, and should be matched to the correct truck setup. Buyers considering this size should confirm that the truck is the radial-equipped sub-model and that the current wheels still match the intended 16.5-inch application.
The 9.50R16.5 marking identifies a radial truck tire with an approximate 9.50-inch nominal section width built for a 16.5-inch wheel. Within the 1981 Dodge Trucks W250 range, this size belongs to the Heavy Duty 8550-GVWR application, where it serves as the radial alternative to the bias-ply 950-16.5. Its importance lies in both the heavier-duty sub-model fitment and the wider section compared with the lighter W250 sizes. This is the size to evaluate when the truck is an 8550-GVWR Heavy Duty model and the goal is to stay with the proper radial-based fitment path.
Fit(s): Heavy Duty (GVWR 8550) and Heavy Duty (GVWR 8550) w/Snow Pkg.
Construction: Bias Ply|Rim: 16.5 in
The 950-16.5 designation is a numeric bias-ply truck size, with the leading number representing an approximate 9.50-inch nominal section width and the final number indicating a 16.5-inch rim. On the 1981 Dodge Trucks W250, this size is tied to Heavy Duty 8550-GVWR applications and also appears on the Heavy Duty Snow Package version. STA offers this size in blackwall form through the Traxion and Super Transport series, and both carry military and truck-oriented character. This size is the correct direction when the truck is one of the heavier W250 configurations and needs the larger bias-ply fitment.
Sub-model fitment on the 1981 Dodge Trucks W250 is not one-size-fits-all. GVWR rating and Snow Package designation can change the tire size, and in some cases the construction type as well, so identifying the exact truck configuration matters before choosing a replacement tire.

Best 1981 Dodge Trucks W250 Tires for Sale
Available W250 tire choices center on STA truck tires in the Super Transport, Traxion, and Transport Highway series. The product range is entirely blackwall and spans multiple bias-ply sizes, with differences in series character, rim-width compatibility, weight, and load capacity where those details are published.
Common W250 tire questions usually come down to the exact sub-model, the correct 16.5-inch tire size, and whether the truck should stay with bias-ply or radial construction. Product selection, restoration appearance, and road-use checks also matter on a working or collector-era pickup like this.
Tire Size & Fitment
What tire size fits a 1981 Dodge Trucks W250?
The 1981 Dodge Trucks W250 does not use one universal tire size across every configuration. Primary fitments include 800-16.5, 875-16.5, 8.00R16.5, 9.50R16.5, and 950-16.5, depending on GVWR and whether the truck has the Snow Package.
The most important step is confirming the exact sub-model before choosing a tire. A 6900-GVWR truck, a 7500-GVWR truck, and an 8550-GVWR Heavy Duty truck can follow different size paths, and some use bias-ply while others use radial construction. Matching the tire to the truck's actual configuration matters more here than simply matching the year and model name.
What size rim does a 1981 Dodge Trucks W250 use?
Every primary tire fitment used on the 1981 Dodge Trucks W250 in this range is built for a 16.5-inch rim. That includes the bias-ply sizes 800-16.5, 875-16.5, and 950-16.5, as well as the radial sizes 8.00R16.5 and 9.50R16.5.
Rim diameter is only the first check, especially on older trucks that may have seen wheel swaps over the years. The wheel should also be appropriate for the intended tire's width and construction, and the truck should be inspected for clearance and setup changes before a replacement is chosen. A W250 with altered wheels should always be measured rather than assumed.
Do all 1981 Dodge Trucks W250 sub-models use the same tire size?
No, 1981 Dodge Trucks W250 sub-models do not all use the same tire size. GVWR and Snow Package designation change the fitment, with lighter versions using 800-16.5 or 875-16.5 and heavier-duty versions moving into the 9.50-size family or radial alternatives.
That variation means the sub-model name matters just as much as the model name. A Heavy Duty 8550-GVWR truck should not be treated the same as a 6900-GVWR or 7500-GVWR W250, even though all are 16.5-inch applications. Checking the truck's actual rating and present wheel setup helps prevent choosing the wrong size path.
Choosing the Right Tire
What should I consider when choosing a tire for a 1981 Dodge Trucks W250?
Start with the exact W250 sub-model, because the 1981 Dodge Trucks W250 uses several different 16.5-inch tire sizes and both bias-ply and radial construction. After the size is confirmed, compare the tire's intended role, whether that means traditional truck appearance, highway use, traction-oriented use, or a heavier-duty application.
Series differences matter once the correct size is established. Options such as STA Super Transport, STA Traxion, and STA Transport Highway give the buyer room to match the truck's use rather than simply buying any tire in the same diameter. Wheel width, load needs, and whether the truck remains stock should all be checked before the final choice is made.
What brands offer tires for the 1981 Dodge Trucks W250?
Available products for the 1981 Dodge Trucks W250 come from STA. Across the applicable sizes, STA appears in several truck-oriented series, including Super Transport, Traxion, and Transport Highway, depending on the exact tire size being selected.
Because the brand selection is narrow, the more useful comparison is usually between tire series within the correct W250 size. A buyer should focus on whether the truck needs the right bias-ply application, a particular load-capacity range where published, or a tread and use profile better suited to highway driving or work duty. Correct fitment remains more important than brand comparison alone.
What tire series are available for the 1981 Dodge Trucks W250?
The 1981 Dodge Trucks W250 has tire availability in STA's Super Transport, Traxion, and Transport Highway series, depending on size. Not every series appears in every W250 tire size, so the correct sub-model and tire code need to be confirmed before comparing product options.
Those series names are useful because they help distinguish the character of the choices once the proper fitment is known. A buyer comparing two correct tires should look at the series, blackwall presentation, weight, and any published load or rim-width information rather than assuming every tire in a matching size serves the same purpose. That approach keeps the decision practical and vehicle-specific.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Dodge Trucks W250?
A period-style 1981 Dodge Trucks W250 usually starts with the correct primary size for the exact sub-model and the construction type that belongs with that application. On this truck, that often means a bias-ply size such as 800-16.5, 875-16.5, or 950-16.5, though some configurations also used radial fitments.
The most authentic-looking result generally comes from matching the truck's proper size family and keeping the overall presentation consistent with its intended era and use. Exact restoration standards can vary by individual truck history, so buyers pursuing high-detail originality should also compare the vehicle against period literature, build records, or marque-specific guidance before making a final appearance decision.
How does tire construction affect the appearance of a restored 1981 Dodge Trucks W250?
Tire construction can noticeably change the look of a restored 1981 Dodge Trucks W250, even when the rim diameter stays the same. Bias-ply truck tires usually preserve a more traditional vintage presentation, while radial tires often give the truck a slightly more modern visual character within the same general size family.
That difference matters most on a truck being restored for era-correct presence rather than utility alone. A buyer deciding between radial and bias-ply should think about how the sidewall shape and overall stance support the truck's intended finish, then confirm that the selected construction matches the sub-model's proper fitment path and wheel setup. Appearance and fitment need to work together.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Dodge Trucks W250?
Yes, modifications can affect tire fitment on a 1981 Dodge Trucks W250 even when the tire size sounds correct on paper. Aftermarket wheels, suspension changes, ride-height adjustments, or brake and hub changes can alter clearance, wheel width suitability, and the way a bias-ply or radial tire sits on the truck.
That is especially important on a W250 because the truck already has several legitimate size paths tied to different sub-models. A modified truck should be checked for actual wheel diameter, wheel width, and tire-to-body or tire-to-steering clearance before replacement tires are chosen. A correct stock fitment should be treated as a starting point, not an automatic answer.
What should I inspect before driving a 1981 Dodge Trucks W250 on new tires?
Before driving a 1981 Dodge Trucks W250 on new tires, inspect wheel condition, mounting surfaces, valve stems, lug hardware, and inflation pressure. The truck should also be checked for obvious alignment or suspension issues that could affect how the new tire wears or how it clears during steering and loaded movement.
A close look at surrounding components is worthwhile on an older three-quarter-ton truck. Steering travel, leaf springs, shocks, and fender clearance should all be verified, particularly if the W250 has seen work use or previous modifications. After the first miles, recheck air pressure and inspect for any signs of rubbing, uneven contact, or abnormal settling.
How should tires on a collector-era 1981 Dodge Trucks W250 be maintained?
Tires on a collector-era 1981 Dodge Trucks W250 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even low-mileage truck tires can age out, develop sidewall cracking, or lose air over time, so appearance alone should never be the only condition test before road use.
Consistent maintenance matters even more when the truck spends long periods parked. Keeping it away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tire, and occasional inspection for bulges, cuts, and flat-spotting is a smart routine. Before any longer drive, confirm that the tires still suit the truck's load demands and present-day wheel setup.
