The 1971 International Pickup 1210 came from an era when International built pickups with a distinctly work-focused character, blending medium-duty influence with light-truck utility. For owners restoring one for shows, using it around the farm, or keeping a survivor on the road, tire fitment matters as much as appearance. This truck uses 16.5-inch bias-ply fitments in 800-16.5, 875-16.5, and 950-16.5, so the first step is confirming which size matches the truck’s actual wheel and setup. Available choices stay true to the truck-minded feel of the period, with blackwall STA options in different series. The right selection depends on wheel width, intended use, and how closely the truck should retain a traditional bias-ply presentation.
Which Tire Size Is Right for The 1971 International Pickup 1210
Three primary tire sizes apply to the 1971 International Pickup 1210, and all of them are bias-ply sizes built for a 16.5-inch rim. Because the same three sizes appear across the covered sub-models, the key step is confirming which wheel and tire setup is actually on the truck before choosing between size, tread style, and load-oriented product differences.
An 800-16.5 size is a vintage numeric bias-ply truck tire where the leading number refers to an approximate 8.00-inch nominal section width and the final number identifies a 16.5-inch rim. On a 1971 International Pickup 1210, it keeps the truck in its original bias-ply sizing family and suits buyers who want a traditional construction. Available STA choices include the Super Transport and Traxion series, both in blackwall form with a Military & Truck focus. This size is worth considering when the truck retains the corresponding wheel setup and a narrower 16.5-inch tire is the goal.
A 875-16.5 tire follows the same vintage numeric bias-ply format, with the 8.75 designation indicating its nominal width class and 16.5 showing the rim diameter. That makes it part of the same period-correct style of fitment used on the 1971 International Pickup 1210, while stepping between the smaller 800 and larger 950 sizes. STA offers this size in blackwall form through the Traxion and Transport Highway series, giving buyers a choice in tread character within the correct construction type. It is the size to evaluate when the truck’s wheel and existing fitment point to a mid-range 16.5-inch setup.
In the 950-16.5 size, the numeric code identifies a vintage bias-ply truck tire with an approximate 9.50-inch nominal section width for a 16.5-inch wheel. For a 1971 International Pickup 1210, this is the largest of the three listed primary sizes and remains firmly in the heavy-duty bias-ply truck tradition. STA offers it in blackwall form in both Traxion and Super Transport series, with Military & Truck construction details and a stated maximum load capacity of 2780 at 60 psi on the applicable products. This size deserves careful wheel-width and clearance confirmation before replacing what is already on the truck.
Fitment is fairly straightforward across the covered 1971 International Pickup 1210 sub-models because each one is associated with the same three 16.5-inch bias-ply tire sizes. Checking the exact sub-model still matters, since stud configuration and GVWR grouping can help confirm that the truck still carries the wheel setup that matches the intended tire size.

Tire Size & Fitment
What tire size fits a 1971 International Pickup 1210?
The 1971 International Pickup 1210 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 16.5-inch rims, and each appears across the covered 1210 sub-models rather than being limited to just one stud or GVWR grouping.
That means the main job is not identifying a unique sub-model-only size, but confirming which wheel and tire combination is actually on the truck today. Many working pickups have had wheels or tires changed over time, so checking the current size, wheel width, and available clearance is the safest way to select the right replacement.
What size rim does a 1971 International Pickup 1210 use?
The tire fitments for a 1971 International Pickup 1210 are built around a 16.5-inch rim diameter. Whether the truck is using 800-16.5, 875-16.5, or 950-16.5 tires, the common factor across those primary sizes is the 16.5-inch wheel.
Rim diameter is only part of the check, though, because wheel width still matters when replacing vintage truck tires. Some available products include stated rim-width ranges, so it is worth measuring the wheel before ordering, especially if the truck has been updated, repurposed, or no longer wears the same wheels it left service with years ago.
Why does the 1971 International Pickup 1210 have more than one tire size?
The 1971 International Pickup 1210 is associated with 800-16.5, 875-16.5, and 950-16.5 because this truck could be found with different tire and wheel setups within the same basic model family. All of those sizes remain bias-ply truck fitments on the same 16.5-inch rim diameter.
That broad fitment range makes the current physical setup more important than assuming one size applies to every surviving truck. A careful replacement decision starts with the size already mounted, the wheel width, and the truck’s intended use, rather than choosing strictly by model name and overlooking changes made during the vehicle’s working life.
Choosing the Right Tire
What should I consider when choosing a 16.5-inch tire for a 1971 International Pickup 1210?
Start with the basics: confirm whether the truck is using 800-16.5, 875-16.5, or 950-16.5, then stay with the correct 16.5-inch bias-ply format. From there, compare the available STA options by tire series, blackwall presentation, and any stated product details such as rim-width range, load capacity, and weight.
The best choice depends on how the pickup is used and how closely the tire should preserve a traditional truck appearance. A restoration-minded truck may prioritize period-style construction, while a truck that still sees regular utility use may lead you to compare tread series and wheel compatibility more closely before making a final selection.
What tire series are available for the 1971 International Pickup 1210?
The available tire series for the 1971 International Pickup 1210 include STA Super Transport, STA Traxion, and STA Transport Highway, depending on the size. Those series are all offered in bias-ply blackwall form and fall within the truck-focused category rather than passenger-car styling themes.
Series differences matter because they give the truck owner a meaningful choice within the correct size family instead of reducing the decision to size alone. Once the proper 800-16.5, 875-16.5, or 950-16.5 fitment is confirmed, comparing the series helps narrow the tire toward the truck’s intended stance, use, and overall presentation.
What rim-width specifications should I compare when choosing 1971 International Pickup 1210 tires?
Rim width is an important comparison point on this truck, especially where the product details provide a stated range. The 800-16.5 STA Super Transport calls for a 6.00 to 6.50-inch rim width, while the 950-16.5 STA products call for a 6.50 to 6.75-inch rim width.
That makes wheel measurement worth the effort before replacing tires on a 1971 International Pickup 1210, particularly if the truck has been altered over the years. Matching a vintage truck tire to the proper wheel width helps maintain the intended tire profile and reduces the chance of selecting a size that does not suit the wheel already on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1971 International Pickup 1210?
A period-style 1971 International Pickup 1210 usually starts with staying in the truck’s original bias-ply sizing family: 800-16.5, 875-16.5, or 950-16.5 on a 16.5-inch rim. The available STA offerings keep that vintage truck character intact with blackwall construction and series such as Super Transport, Traxion, and Transport Highway.
The right period-style choice depends on the truck’s actual wheel setup and how the finished vehicle is meant to look and work. If originality matters down to a specific presentation detail, it is wise to compare the truck against marque references, old photos, or build-related documentation before deciding which size and series best support the restoration.
How does tire construction affect the appearance of a restored 1971 International Pickup 1210?
On a restored 1971 International Pickup 1210, bias-ply construction plays a major role in preserving the truck’s traditional visual character. Because the primary fitments here are all bias-ply 16.5-inch truck tires, the sidewall shape and overall presentation remain closer to what buyers expect from a working pickup of that era.
Appearance is only one piece of the decision, but it is an important one on a vintage International. Tire size, tread series, and wheel width all influence how the truck sits and looks, so a restoration-oriented owner should think beyond diameter alone and choose a tire that supports both the intended stance and the truck’s period-style personality.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1971 International Pickup 1210?
Yes, modifications can affect tire fitment on a 1971 International Pickup 1210 even when the truck stays within the 16.5-inch rim family. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body modifications can influence whether 800-16.5, 875-16.5, or 950-16.5 remains the sensible choice.
A truck that has spent decades in service may no longer match its original setup, so a quick visual assumption is not enough. Checking wheel dimensions, steering clearance, and the space around the fenders and suspension before ordering helps avoid selecting a size that looks appropriate on paper but does not suit the truck in practice.
What should I inspect before driving a 1971 International Pickup 1210 on new tires?
Before putting a 1971 International Pickup 1210 back on the road with new tires, inspect the wheels, lug hardware, valve stems, and overall wheel condition along with the tire installation itself. It also makes sense to confirm inflation, look for any interference at full steering lock, and verify that the replacement size matches the truck’s actual setup.
Collector and work trucks often sit for long stretches, so the first drive should include a cautious recheck after a short distance. Watching for air loss, rub marks, vibration, or unusual handling can reveal mounting or clearance issues early, before the truck is asked to carry load or spend time at sustained road speed.
How should 16.5-inch tires on a collector 1971 International Pickup 1210 be maintained?
Tires on a collector 1971 International Pickup 1210 should be maintained with regular pressure checks, visual inspections, and attention to age-related deterioration as much as tread wear. Even when mileage stays low, vintage-use trucks can develop cracking, flat spotting, bulges, or slow air loss simply from time, storage conditions, and infrequent use.
Good maintenance includes keeping the truck stored away from prolonged sunlight, excess moisture, and ozone sources, then inspecting the tires before each outing. Periodic checks of tread condition, sidewalls, and wheel condition help preserve both safety and presentation, especially on a bias-ply truck tire that may spend more time parked than actively driven.
