1971 International Pickup 1010 Tires

The 1971 International Pickup 1010 uses two primary tire sizes: G78-15 and H78-15. Both are vintage alphanumeric bias-ply sizes built for 15-inch rims, and both appear across the covered sub-models for this truck.

That means the first step is confirming which size is actually correct for the truck in front of you rather than assuming every 1010 left with the same tire. Checking the existing wheel width, the tire size already mounted, and any past changes to wheels or stance will help determine whether G78-15 or H78-15 is the better match before moving on to sidewall style or radial-equivalent choices.

Both primary tire sizes used on the 1971 International Pickup 1010 are built around a 15-inch rim diameter. That applies to G78-15 and H78-15, so rim diameter stays consistent even though the truck has two tire-size options.

Rim diameter is only part of the fitment picture, so it still helps to verify the actual wheel width before ordering tires. Product specifications for these sizes show differences in rim-width compatibility, and that matters if the truck has replacement wheels, older aftermarket steel wheels, or a setup that has changed over time.

The 1971 International Pickup 1010 has two primary sizes, G78-15 and H78-15, because this truck can be found with more than one original-style tire fitment. Both are bias-ply sizes for 15-inch wheels, but they represent different size classes within the same vintage sizing system.

The practical takeaway is that size selection should follow the truck's actual wheel and tire setup, not just the model name. Looking at the tire currently on the vehicle, measuring wheel width, and checking for suspension or wheel changes will help narrow the choice before comparing whitewall passenger-style options against blackwall truck-oriented tread designs.

On the 1971 International Pickup 1010, both G78-15 and H78-15 are primary bias-ply tire sizes. They use the older alphanumeric sizing system common to many trucks and passenger vehicles of the period and are not radial sizes in their original fitment form.

That distinction matters because a bias-ply tire preserves the traditional construction and look associated with the truck's era. Anyone considering a radial alternative should treat that as a conversion decision rather than the same thing in a different casing, and should compare wheel width, tire dimensions, and clearance before changing construction.

G78-15 has four radial equivalents: 205R15, P215/75R15, P225/70R15, and 710R15 as a bias-look radial. H78-15 also has four: 215R15, P225/75R15, P235/70R15, and 760R15 as a bias-look radial, giving the 1971 International Pickup 1010 several modern-format alternatives.

Those choices differ by sizing convention and profile, so the decision is not simply radial versus bias-ply. A bias-look radial keeps a more vintage visual character, while the metric and P-metric options use more modern size formats; any of them should be checked against wheel width, overall vehicle setup, and available clearance before conversion.

Start by identifying whether the truck currently uses G78-15 or H78-15, then match that primary size to its actual radial-equivalent options. The recommended rim-width range for the listed equivalents is 6-8 inches, so wheel width is one of the first measurements worth confirming on a 1971 International Pickup 1010.

Tire conversion should also account for real-world clearance at the fenders, steering components, and suspension, especially on an older truck that may have seen wheel or ride-height changes over the years. It also helps to think about the goal of the change, since a bias-look radial gives a different visual result than a metric or P-metric radial.

The first consideration is using the correct primary size for the truck, since the 1971 International Pickup 1010 can use either G78-15 or H78-15. After size is confirmed, the main choices become construction style, sidewall appearance, load specification, and whether the truck is being set up for restoration-minded display or more utility-focused driving.

A wide whitewall Coker Classic creates a very different impression than an STA blackwall truck-style tire, even within the same size family. Wheel width should be compared alongside those appearance choices, and the truck's intended use should guide whether a more passenger-style period look or a heavier-duty visual treatment makes the most sense.

The available sidewall styles for the 1971 International Pickup 1010 are wide whitewall and blackwall. Both G78-15 and H78-15 include wide whitewall options in the Coker Classic line, while blackwall choices appear in the STA truck-oriented offerings.

That makes sidewall style one of the biggest appearance decisions on this truck. A wide whitewall tends to suit a more restoration-oriented or custom vintage presentation, while a blackwall keeps a more utilitarian truck look, so the right choice depends on whether the pickup is being finished as a period-style cruiser, work-themed build, or simple driver.

The 1971 International Pickup 1010 has tire options from Coker Classic and STA in its primary G78-15 and H78-15 sizes. Those brands cover different visual directions, with Coker Classic focused here on wide whitewall bias-ply offerings and STA represented by blackwall truck-style bias-ply designs.

Brand choice should be treated as part of the overall tire character rather than a ranking exercise. It helps to compare the sidewall treatment, tire series, rim-width specification where given, and load figures where available so the selected tire matches the pickup's look, wheel setup, and intended driving use.

A period-style 1971 International Pickup 1010 usually starts with one of its original-type bias-ply sizes, G78-15 or H78-15, confirmed against the truck's actual wheel setup. Within those sizes, the visual direction can move toward a passenger-style wide whitewall or toward a more work-truck blackwall presentation.

The right answer depends on how the pickup is being restored or presented, because both the size and the sidewall treatment shape the truck's overall character. If exact historical originality matters beyond a general vintage look, it is worth comparing the truck against marque references, old photos, or build documentation before settling on a specific sidewall style.

Tire construction changes the visual character of a restored 1971 International Pickup 1010 as much as the size or sidewall treatment. A bias-ply tire keeps the truck in its original-era construction style, while a radial equivalent can shift the presentation toward a more modern look depending on the exact size format chosen.

That is why construction should be considered alongside the restoration goal rather than as a hidden technical detail. A bias-look radial can bridge that gap for some owners, while a metric or P-metric radial reads more modern, so the final decision should reflect whether the truck is meant to emphasize traditional appearance, road use, or a balance of both.

Yes, modifications can affect tire fitment on a 1971 International Pickup 1010 even when the tire size itself is correct in principle. Changes such as aftermarket wheels, different wheel widths, altered suspension height, brake conversions, or bodywork repairs can all influence how a G78-15, H78-15, or radial equivalent sits on the truck.

That is why a vintage pickup should be checked as an individual vehicle before new tires are chosen. Steering clearance, fender space, and wheel dimensions all matter, and older trucks often have decades of changes behind them, so a quick inspection can prevent ordering a tire that suits the model on paper but not the truck as it stands now.

Before driving a 1971 International Pickup 1010 on new tires, inspect the wheels for damage, confirm lug hardware is correct for the truck, and make sure the tires are mounted in the right size for the wheel setup. It also helps to look over steering and suspension components so the new tires are not being asked to work around existing mechanical issues.

Once mounted, tire pressure, bead seating, and visible clearance at full steering lock deserve a final check. A short, careful road test is useful on an older pickup, because it can reveal rubbing, pull, vibration, or air loss early, before the truck is taken on a longer drive or put back into regular use.

Collector-use G78-15 or H78-15 tires on a 1971 International Pickup 1010 should be inspected regularly for air loss, sidewall cracking, cuts, bulges, and uneven tread wear. Vintage trucks often spend long periods parked, so tire condition should be checked by time and storage exposure as well as by miles driven.

Clean, dry storage away from prolonged sunlight, heat, and ozone sources helps preserve tires on a low-use pickup. Pressure should be kept at the correct operating level for the tire being used, and the truck should be looked over before each driving season so aging components or long-term flat spotting do not cut into safe road use.
