1972 International Pickup 1110 Tires

The 1972 International Pickup 1110 uses three primary bias-ply tire sizes: 700-15, G78-15, and H78-15. All three are 15-inch fitments, and both covered stud-pattern versions of the 1110 share that same size range rather than using separate sub-model-specific tire diameters.

The practical step is confirming which size is already on the truck and whether the wheel width supports the tire being considered. Since more than one primary size applies, the choice often comes down to the truck’s current wheel setup, the look you want, and whether a more passenger-style whitewall or a more truck-oriented blackwall pattern makes the most sense.

The primary tire sizes for the 1972 International Pickup 1110 all use a 15-inch rim diameter. That includes 700-15, G78-15, and H78-15, so rim diameter stays consistent even though the truck can use more than one vintage tire size format.

Rim diameter is only part of the fitment picture, especially on an older pickup that may have had wheels changed over time. It helps to verify the actual wheel width before choosing among these sizes, because the available products do not all share the same rim-width range and that can affect how comfortably a particular tire suits the truck.

The covered 1972 International Pickup 1110 sub-models use the same three primary tire sizes: 700-15, G78-15, and H78-15. Both the 1/2-20 studs version and the 5/8-18 studs version share the same 15-inch bias-ply fitment range.

That consistency simplifies tire shopping, because the sub-model distinction does not change the size family itself. Even so, it is still smart to confirm the truck’s actual wheels and existing tire size before replacing anything, especially if the pickup has been restored, modified, or converted to a different wheel style at some point in its life.

G78-15 is a bias-ply tire size on the 1972 International Pickup 1110. It is part of the truck’s primary vintage fitment range and uses the older alphanumeric sizing system rather than a modern radial metric format.

That matters because a bias-ply tire keeps the truck in a more traditional construction and appearance category. If a radial alternative is being considered instead, the choice should be treated as a conversion decision rather than simply another version of the same tire, with attention given to wheel width, overall dimensions, and how the truck is expected to be driven.

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

Those choices give the 1972 International Pickup 1110 several different radial sizing conventions to compare, from Euro-metric to P-metric and bias-look radial formats. A 6-8 inch rim-width range is associated with these equivalents, but wheel compatibility and vehicle clearance still need to be checked carefully before moving away from the truck’s original-style bias-ply sizing.

Start by confirming which primary size the truck uses, then compare the intended radial equivalent for rim diameter, rim-width suitability, and overall space in the wheel opening. On a 1972 International Pickup 1110, radial equivalents are available for G78-15 and H78-15, but they still need to be evaluated against the truck’s actual wheel setup.

A careful conversion also includes checking steering clearance, suspension condition, and whether the truck has non-stock wheels or ride-height changes. Many older pickups have been altered over time, so the safest approach is to treat the radial as an alternative size relationship, then verify compatibility at the wheel and on the vehicle before making the switch.

The main considerations are correct size, 15-inch rim compatibility, bias-ply construction, and the character you want the truck to have. A 1972 International Pickup 1110 can be fitted with 700-15, G78-15, or H78-15, so the right choice depends on the wheel setup already on the truck and the type of tire presentation you want.

Some owners prioritize a wide whitewall restoration-style look, while others need a blackwall truck tire with highway or traction-oriented character. Product differences such as rim-width range, load figures where stated, and tread style can matter just as much as sidewall appearance, especially if the pickup will be used for more than occasional display driving.

The available sidewall styles for 1972 International Pickup 1110 tires are blackwall and wide whitewall. Those styles appear across the truck’s 700-15, G78-15, and H78-15 bias-ply options, with some sizes leaning more heavily toward truck-style blackwalls and others offering passenger-style whitewall presentation.

That choice has a strong effect on how the truck reads visually. A blackwall generally suits a more work-focused or utility-oriented look, while a wide whitewall can push the pickup toward a more polished vintage presentation. The best choice depends on the era you want to emphasize and whether the truck is being restored for display, cruising, or practical road use.

Tires for the 1972 International Pickup 1110 are available from Firestone, BFGoodrich, Coker Classic, and STA. Those brands cover the truck’s primary 700-15, G78-15, and H78-15 bias-ply sizes with a mix of wide whitewall, blackwall, classic passenger-style, and truck-oriented tire series.

Brand alone should not drive the decision. It makes more sense to compare the actual size being used, the sidewall treatment, the tire series, and the wheel-width requirements of the specific product. On an older pickup, selecting a tire that matches the truck’s use and appearance goal is usually more important than simply choosing from the broadest brand name.

A period-style 1972 International Pickup 1110 should start with one of its primary bias-ply sizes: 700-15, G78-15, or H78-15. Keeping the truck in a bias-ply construction preserves the vintage sizing language and overall presentation that suits an early 1970s International pickup.

From there, the choice depends on how the truck is being presented. Wide whitewall versions create a more dressed vintage appearance, while blackwall truck-style tires keep a more utilitarian look. When exact restoration accuracy matters, compare your truck’s current configuration with marque-specific references and the vehicle’s own history before settling on a sidewall style or size.

Tire construction has a noticeable effect on the look of a restored 1972 International Pickup 1110 because the truck’s primary fitment is bias-ply. A bias-ply tire keeps the vintage size format and traditional visual character that many restoration-minded owners want from an early 1970s light truck.

A radial alternative can change the presentation, especially when it uses a modern metric sizing format. That does not automatically make it the wrong choice, but it shifts the truck away from a strictly original-style look. Owners balancing appearance and road use often compare standard metric radials with bias-look radial options when preserving visual character matters.

Yes, modifications can affect tire fitment on a 1972 International Pickup 1110 even when the truck stays within a 15-inch wheel diameter. Changes such as aftermarket wheels, different wheel widths, altered offset, suspension work, or body adjustments can all influence how a 700-15, G78-15, or H78-15 tire sits and clears.

That is why an older pickup should be measured as it currently exists, not only by what it used when new. A tire that matches the correct vintage size family still needs enough room at full steering angle and under suspension movement, and the wheel itself has to suit the intended tire’s rim-width requirements.

Check wheel condition, valve stems, mounting hardware, and inflation before putting a 1972 International Pickup 1110 back into regular road use on new tires. It also helps to confirm that the tire size installed matches the truck’s chosen fitment and that each tire has adequate clearance around fenders, suspension parts, and steering components.

A short test drive followed by a recheck is a smart habit on an older truck. Look for any signs of rubbing, uneven stance, vibration, or air loss after the first miles. Since vintage pickups often spend long periods parked, it is also wise to inspect brake condition and general suspension health before assuming the new tires are the only road-use variable.

Collector tires on a 1972 International Pickup 1110 should be kept properly inflated, inspected regularly, and protected from long periods of heat, sunlight, and moisture. Whether the truck uses 700-15, G78-15, or H78-15, the same basics apply: watch for cracking, cuts, bulges, uneven wear, and any gradual loss of air.

Low-mileage collector use can make age and storage condition just as important as tread depth. Moving the truck occasionally helps reduce flat-spotting, and clean, dry storage away from ozone sources can help preserve the tires over time. Any sign of sidewall deterioration or persistent air loss should be addressed before putting the pickup back on the road.
