1972 International Pickup 1010 Tires

The 1972 International Pickup 1010 uses two primary tire sizes: G78-15 and H78-15. Both are vintage alphanumeric bias-ply sizes designed for 15-inch rims, and both appear on the covered versions of the 1010 rather than being limited to only one stud-pattern sub-model.

That means the first step is checking which size is already on the truck and confirming the actual wheel setup before choosing a replacement. A truck with original-style wheels may still have either size, while a modified truck may need added verification for wheel width, clearance, and overall stance before moving ahead.

The primary tire sizes for the 1972 International Pickup 1010, G78-15 and H78-15, both use a 15-inch rim diameter. That keeps rim diameter simple on this truck, because the tire-size choice does not change the wheel diameter requirement within the covered fitment range.

Rim diameter is only one part of the fitment picture, though, especially on an older pickup that may have seen wheel changes over the years. It is worth measuring the wheel and checking its width before selecting between G78-15, H78-15, or one of the radial-equivalent options that also need to be matched carefully to the wheel.

The covered 1972 International Pickup 1010 sub-models share the same primary tire-size range. Both the 1/2-20 studs version and the 5/8-18 studs version use G78-15 and H78-15 bias-ply tires on 15-inch rims.

That shared fitment makes the buying process easier, because the stud-pattern distinction does not create a separate tire-size rule here. The practical choice comes down to determining which of the two sizes is actually on the truck now, then selecting the tire style and construction approach that matches its wheels, appearance, and intended use.

G78-15 is a bias-ply tire size for the 1972 International Pickup 1010. It uses the vintage alphanumeric sizing system and belongs to the truck's primary period-style fitment rather than being a modern metric or P-metric radial size.

Staying with bias-ply preserves the traditional construction and appearance associated with trucks of this era. Moving away from it can change both the look and the way the truck responds on the road, so any radial conversion should begin with wheel-width confirmation, size comparison, and a careful clearance check rather than assuming the original and alternative sizes behave the same.

For G78-15, radial equivalents include 205R15, P215/75R15, P225/70R15, and 710R15 as a bias-look radial. For H78-15, the equivalent choices are 215R15, P225/75R15, P235/70R15, and 760R15 as a bias-look radial.

Those options give the 1972 International Pickup 1010 several paths, from Euro-metric and P-metric radial sizing to a radial that keeps a more traditional visual presentation. The recommended rim-width range for these equivalent groupings is 6 to 8 inches, and each option should still be checked against the truck's wheel dimensions and available steering and fender clearance.

A 1972 International Pickup 1010 owner considering radial tires should start by matching the radial equivalent to the truck's original G78-15 or H78-15 size. The wheel's 15-inch diameter is only the beginning; wheel width, tire dimensions, and the truck's actual suspension and body clearance also need to line up with the alternative size.

Construction changes can affect both appearance and overall road feel, so the decision should reflect how the truck is used and how period-oriented it needs to remain. Many owners also benefit from inspecting steering clearance lock to lock, checking rear-fender room under load, and verifying that any aftermarket wheels have not altered the fitment window.

The main factors are correct size, 15-inch rim compatibility, and the kind of presentation the truck should have once the tires are mounted. G78-15 and H78-15 are both valid bias-ply sizes for the 1972 International Pickup 1010, but the available products vary in sidewall style, tire series, truck-oriented character, and load specifications.

A whitewall Coker Classic gives the truck a more restoration-oriented look, while an STA blackwall leans more toward utility styling. It also helps to compare the wheel width against the tire's intended range, especially on older trucks that may no longer wear their original wheels or may have a different stance than they did when new.

The available sidewall styles for the 1972 International Pickup 1010 are wide whitewall and blackwall. Both G78-15 and H78-15 can be found in wide whitewall form through Coker Classic, while blackwall truck-style options are available through STA in the Super Traxion and Traxion lines.

That gives the truck two clearly different visual directions. Wide whitewalls suit owners aiming for a more vintage street or restoration appearance, while blackwalls usually make more sense when the goal is a more utilitarian truck look. Choosing between them is less about fitment than about how the finished pickup should present once the tires are installed.

Tires for the 1972 International Pickup 1010 are available from Coker Classic and STA in the covered G78-15 and H78-15 sizes. Those brands represent two distinct directions within the same fitment range, with Coker Classic centered on traditional whitewall offerings and STA focused on blackwall truck-style options.

The brand choice should follow the truck's intended use and appearance rather than a simple name preference. It is smart to compare series, sidewall treatment, rim-width suitability where stated, and load figures when available, since two tires in the same nominal size can still serve different goals on a vintage International pickup.

A period-style 1972 International Pickup 1010 starts with the correct primary fitment family, which means G78-15 or H78-15 in bias-ply construction on a 15-inch rim. Within that range, the decision usually becomes whether the truck should lean toward a more passenger-style whitewall presentation or a more utilitarian blackwall truck look.

That choice depends on how the pickup is being restored and the visual effect desired once it is on the ground. Owners who want maximum historical accuracy should compare tire appearance against photos, marque references, and vehicle-specific documentation, because a correct size alone does not automatically settle the most appropriate sidewall treatment.

Tire construction has a visible effect on a restored 1972 International Pickup 1010 because the truck's original-style fitment centers on bias-ply sizes G78-15 and H78-15. Bias-ply tires tend to preserve the traditional profile and visual character associated with early 1970s light trucks more naturally than modern radial formats.

A radial equivalent can still be a sensible choice, especially when road use matters, but it may change the truck's overall presentation depending on the specific size and sidewall style selected. A bias-look radial helps bridge that gap, which is why it appeals to owners trying to balance a vintage appearance with a different construction approach.

Yes, modifications can affect tire fitment on a 1972 International Pickup 1010 even when the tire size itself falls within the normal G78-15 or H78-15 range. Aftermarket wheels, different wheel widths, altered ride height, brake changes, or body and suspension work can all influence how much room the tire has once mounted.

That matters even more if the truck is being considered for a radial-equivalent size instead of its original-style bias-ply construction. A smart check includes wheel diameter, wheel width, inner and outer clearance, and steering travel, since an older pickup may have drifted away from stock specifications over decades of repairs and upgrades.

Before driving a 1972 International Pickup 1010 on new tires, inspect the wheels, confirm proper mounting, and verify that the chosen size matches the truck's intended fitment. It is also worth checking valve stems, lug hardware, visible wheel condition, and basic clearance at the fenders and steering components.

Once the tires are installed, pay attention to air retention, sidewall condition, and whether anything rubs during turns or suspension movement. A short test drive followed by a second inspection is a useful habit on a vintage truck, especially one that may have old suspension parts, replacement wheels, or long periods of storage in its past.

G78-15 and H78-15 tires on a collector 1972 International Pickup 1010 should be kept properly inflated, inspected regularly, and protected from long-term exposure to sunlight, moisture, and ozone sources during storage. Even low-mileage vintage trucks need routine checks for cracking, bulges, cuts, uneven wear, and gradual air loss.

Maintenance also includes watching how the truck sits and drives over time, because steering or suspension wear can show up first at the tires. A stored vehicle benefits from periodic movement or repositioning to avoid prolonged static loading, and any tire that shows age-related deterioration deserves closer evaluation before the pickup returns to road use.
