The 1971 International Pickup 1310 came from an era when International built work-focused trucks with a straightforward, heavy-duty character that still appeals to restorers, farm-truck owners, and vintage truck enthusiasts. For this exact model, tire selection starts with one of three 16.5-inch bias-ply sizes: 800-16.5, 875-16.5, or 950-16.5. That makes the main decision less about modern styling trends and more about matching the truck’s actual wheel and load setup to the correct period-style commercial tire. Available choices stay true to the truck’s purpose, with blackwall STA truck tires offered in multiple series for highway or traction-oriented use.
Which Tire Size Is Right for The 1971 International Pickup 1310
Three primary tire sizes apply to the 1971 International Pickup 1310, and all of them are bias-ply tires built for a 16.5-inch rim. Because both covered GVWR versions can use the same size range, the first step is confirming which wheel and tire size is actually on the truck before choosing among the available commercial-style tire series.
The 800-16.5 size uses a vintage numeric bias-ply format in which the leading number refers to an approximate nominal section width of 8.00 inches, while 16.5 identifies the wheel diameter. On a 1971 International Pickup 1310, this is a bias-ply truck fitment that suits owners staying with a traditional heavy-duty tire construction. Available options include STA Super Transport and STA Traxion, both in blackwall form. This size is worth considering when the truck is already set up for the narrower end of the 16.5-inch fitment range and the goal is to keep a period-style commercial look.
The 875-16.5 designation follows the same vintage numeric bias-ply system, with 8.75 indicating the nominal section width class and 16.5 identifying the rim diameter. This keeps the 1971 International Pickup 1310 in a traditional bias-ply truck tire format rather than moving into a modern radial conversion. In this size, STA offers blackwall choices in the Traxion and Transport Highway series, giving buyers a useful distinction between tread character and intended truck use. It is a sensible size to evaluate when the truck needs a middle-ground commercial fitment within the original 16.5-inch family.
The 950-16.5 size is another vintage numeric bias-ply designation, with 9.50 representing the nominal section width class and 16.5 marking the wheel diameter. For a 1971 International Pickup 1310, this is the widest of the listed primary sizes and remains firmly in the truck-oriented bias-ply category. STA offers blackwall choices in the Traxion and Super Transport series, and both carry stated load figures of 2780 at 60 psi. This size deserves careful wheel-width and clearance confirmation before selection, especially on a truck that may have seen wheel changes over time.
Fitment is relatively straightforward across the covered 1971 International Pickup 1310 sub-models because both GVWR versions use the same three bias-ply tire sizes. The important check is not trim-specific sizing, but confirming the actual wheel and tire setup currently on the truck.

1971 International Pickup 1310 (GVWR 7000)
The GVWR 7000 version uses the same 16.5-inch bias-ply size range as the other covered 1310 configuration. That means tire selection centers on confirming whether the truck is set up for 800-16.5, 875-16.5, or 950-16.5 and then choosing the tread series that best matches its use.
The GVWR 9000 version shares the same primary 16.5-inch bias-ply fitment range, so sub-model choice does not narrow the tire size by itself. Selection still comes down to the actual wheel and tire combination on the truck, along with whether a highway-style or traction-oriented tread makes more sense.
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.

Available 1971 International Pickup 1310 tires stay focused on traditional bias-ply truck fitment, with STA offerings across the Super Transport, Traxion, and Transport Highway series. Comparison points include size, tread series, blackwall appearance, stated rim-width compatibility on some sizes, and commercial-style load characteristics.
Common questions for the 1971 International Pickup 1310 usually come down to choosing among its three bias-ply 16.5-inch tire sizes, understanding what those size codes mean, and checking wheel, clearance, and restoration factors before road use.
Tire Size & Fitment
What tire size fits a 1971 International Pickup 1310?
A 1971 International Pickup 1310 uses one of three primary bias-ply tire sizes: 800-16.5, 875-16.5, or 950-16.5. All three sizes are built for a 16.5-inch rim, and both covered GVWR versions of the 1310 use that same size range rather than having separate sub-model-specific tire sizing.
The practical step is confirming which size is actually mounted on the truck now and whether the wheels match that size correctly. Since more than one primary size applies, the right choice depends on the truck’s present wheel setup, available clearance, and whether a narrower, mid-range, or wider commercial-style tire best suits the vehicle.
What size rim does a 1971 International Pickup 1310 use?
The 1971 International Pickup 1310 uses a 16.5-inch rim with its primary tire fitments. The listed tire sizes for this truck are 800-16.5, 875-16.5, and 950-16.5, and the 16.5 designation in each size points to the wheel diameter those tires are built to fit.
Wheel diameter is only part of the picture, so it is still important to confirm the wheel width before selecting a tire. Some available products also show specific rim-width ranges, particularly in 800-16.5 and 950-16.5, which makes it worthwhile to verify the actual wheel dimensions on the truck rather than relying on appearance alone.
What does 800-16.5 mean on a 1971 International Pickup 1310?
On a 1971 International Pickup 1310, 800-16.5 is a vintage numeric bias-ply truck tire size. The 800 portion refers to an approximate nominal section width of 8.00 inches, while 16.5 is the wheel diameter in inches. It is a traditional commercial-style sizing format rather than a modern metric radial designation.
Understanding that code helps when comparing the 1310’s other listed sizes, 875-16.5 and 950-16.5, because each one remains within the same 16.5-inch wheel family but changes width class. That means the truck owner should compare the actual wheel setup, tire clearance, and intended use before moving from one listed size to another.
Choosing the Right Tire
What should I consider when choosing a 950-16.5 tire for a 1971 International Pickup 1310?
A 950-16.5 tire for a 1971 International Pickup 1310 should first be chosen by confirming that the truck is actually set up for that size and not one of the narrower listed options. In this size, available STA tires are bias-ply blackwalls in the Traxion and Super Transport series, with stated load figures of 2780 at 60 psi.
Selection then comes down to practical details such as tread style, wheel-width compatibility, and the truck’s intended use. The listed 950-16.5 products show a 6.50 to 6.75 inch rim-width range, so checking the wheel itself matters before ordering, especially on a vintage truck that may have had wheels replaced over the years.
What brands offer tires for the 1971 International Pickup 1310?
STA is the brand offered across the available tire sizes for the 1971 International Pickup 1310. Its products cover all three primary bias-ply sizes and appear in several truck-oriented series, including Super Transport, Traxion, and Transport Highway, giving the truck owner more than one period-style commercial tire choice within the correct fitment family.
Since the brand selection is focused, the more important comparison is between size and series rather than chasing different brand names. Looking at tread style, blackwall presentation, load-related specifications where stated, and rim-width compatibility on the larger sizes will usually do more to narrow the right tire than brand alone.
What tire series are available for the 1971 International Pickup 1310?
The 1971 International Pickup 1310 is served by several STA tire series, including Super Transport, Traxion, and Transport Highway. Those series appear across the truck’s listed 800-16.5, 875-16.5, and 950-16.5 bias-ply sizes, all in blackwall form and all aimed at traditional truck use rather than modern passenger-car styling.
That series variety matters because the first decision is still the correct tire size, while the second is the kind of tread character that suits the truck’s role. A restoration-minded display truck, a working vintage pickup, and a road-driven utility vehicle may all use the same basic size family but favor different series within it.
Restoration & Appearance
Which tire should I choose for a period-style 1971 International Pickup 1310?
A period-style 1971 International Pickup 1310 starts with one of its correct primary bias-ply sizes: 800-16.5, 875-16.5, or 950-16.5 on a 16.5-inch rim. That keeps the truck in the same traditional commercial tire format associated with its working-truck era rather than changing the visual impression with a modern metric radial conversion.
The best period-style choice depends on the wheel and tire size already on the truck, along with how closely the owner wants to preserve a vintage heavy-duty appearance. When exact restoration authenticity matters, it helps to compare tire details with marque-specific references, old photos, or build documentation before settling on a specific size and tread series.
How does tire construction affect the appearance of a restored 1971 International Pickup 1310?
Tire construction has a strong visual effect on a restored 1971 International Pickup 1310 because its listed primary fitments are all bias-ply truck tires. Staying with a bias-ply tire preserves the traditional commercial look of the sidewall and overall presentation, which is often an important part of how a vintage International pickup is perceived.
Appearance is only one factor, but it matters more on an older truck than many owners expect. Even within the correct size family, tread series and stance can subtly change the truck’s character, so it is worth balancing restoration goals with the truck’s actual road use and making sure the selected tire still matches the wheel setup properly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1971 International Pickup 1310?
Yes, modifications can affect tire fitment on a 1971 International Pickup 1310 even when the tire size is one of the listed 16.5-inch bias-ply options. Wheel changes, altered ride height, brake conversions, or body and suspension work can all change how much room the truck has for 800-16.5, 875-16.5, or 950-16.5 tires.
A truck that has been updated over the years should be checked as it sits today rather than assumed to match original wheel dimensions. Clearance at the fender, steering components, and suspension points matters, and the wider 950-16.5 size especially deserves a careful look before the owner commits to a replacement tire.
What should I inspect before driving a 1971 International Pickup 1310 on new tires?
Before driving a 1971 International Pickup 1310 on new tires, inspect the wheels for correct diameter and condition, make sure the tires are seated properly, and verify inflation before road use. It is also wise to check lug hardware, look for any interference at full steering travel, and confirm that the truck is sitting evenly.
A short, careful test drive should follow, with attention to vibration, pull, rubbing, or unusual steering feel. Vintage trucks often spend long periods parked, so it also helps to inspect suspension bushings, steering parts, and brake condition at the same time rather than treating the tire change as an isolated maintenance step.
How should 800-16.5, 875-16.5, or 950-16.5 tires on a collector 1971 International Pickup 1310 be maintained?
Tires on a collector 1971 International Pickup 1310 should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Bias-ply truck tires in sizes such as 800-16.5, 875-16.5, and 950-16.5 deserve periodic attention for cracking, bulges, cuts, uneven wear, and slow air loss, especially if the truck is driven only occasionally.
Low-use collector vehicles often age their tires before they wear them out, so tread depth alone is not enough. Keeping the truck away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires, and occasional inspections of wheel condition and alignment can catch problems before they affect road manners.
