1973 International Travelall 1010 Tires

The 1973 International Travelall 1010 uses three primary tire sizes: 700-15, G78-15, and H78-15. All three are bias-ply sizes built for 15-inch rims, so the vehicle does not rely on a single modern-style metric fitment.

The practical next step is to confirm which of those sizes is actually on the Travelall now and whether the wheels match the size being considered. Since 700-15, G78-15, and H78-15 can lead to different product types and different radial-equivalent paths, checking the current wheel and tire setup first helps avoid choosing a size that does not match the vehicle's existing configuration.

The covered tire sizes for a 1973 International Travelall 1010 all fit a 15-inch rim. That includes 700-15, G78-15, and H78-15, so rim diameter stays consistent even though the tire sizing systems differ.

Rim diameter is only part of the fitment picture, especially on an older utility vehicle that may have seen wheel changes over time. It helps to verify the actual wheel width as well, since the available products in these sizes do not all share the same rim-width range. Looking at the wheel itself before ordering is especially important when switching between a narrower 700-15 setup and the larger alphanumeric sizes.

The two covered 1973 International Travelall 1010 sub-models, distinguished by 1/2-20 studs and 5/8-18 studs, share the same three primary tire sizes: 700-15, G78-15, and H78-15. Both versions also stay with bias-ply construction on 15-inch rims.

That makes the sub-model decision simpler than on vehicles where trim level changes the fitment outright. Even so, the stud pattern is still worth confirming because wheel and hub hardware matter on a truck-based vehicle, and many Travelalls have been altered during their working lives. Once the wheel setup is confirmed, the main decision becomes selecting the size and tire style that best matches the vehicle's current use and appearance goals.

G78-15 is a bias-ply primary tire size for the 1973 International Travelall 1010. It uses the vintage alphanumeric sizing system rather than a modern radial size format, even though radial equivalents are available for buyers considering an alternative construction.

That distinction matters because keeping G78-15 in bias-ply form preserves the original-style sizing language and opens up period-style whitewall or truck-oriented blackwall choices within that construction. A move to a radial equivalent should be treated as a separate fitment decision, with attention paid to wheel width, overall tire dimensions, and body or steering clearance rather than assuming that every 15-inch radial option behaves the same on the Travelall.

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

Those options give the Travelall owner several ways to stay near the original fitment intent while changing sizing convention or construction style. The 205R15 and 215R15 sizes follow the Euro-metric radial format, the P-metric choices step into 75-series or 70-series profiles, and the 710R15 or 760R15 choices keep a more traditional visual character. A 6-8 inch rim-width range is relevant, and the final choice should still be checked against wheel compatibility and clearance.

Start by confirming which primary size the Travelall uses now, because radial equivalents are given for G78-15 and H78-15, not for every primary size shown here. Wheel diameter should remain 15 inches, and the wheel width should also be checked against the radial size being considered.

A careful conversion also means comparing the vehicle's real-world setup rather than the tire size alone. Clearance at the fenders, steering components, and suspension should be inspected, especially on a full-size truck-based wagon that may have replacement springs, aftermarket wheels, or a changed ride height. It is also smart to think about the vehicle's intended use, since a period-style bias-ply presentation and a radial alternative can lead to a different overall character.

Begin with the size already matched to the Travelall's wheels, since 700-15, G78-15, and H78-15 are all primary fitments but not interchangeable assumptions. Construction stays bias-ply across the primary sizes, yet the available tires differ in brand, tread character, sidewall treatment, and supported rim-width ranges.

A restoration-minded Travelall may point toward a wide whitewall bias-ply, while a more utility-focused truck setup may favor a blackwall truck-pattern tire. Looking at rim width, load figures where given, and whether the vehicle sees mostly display use, local driving, or more regular road time will help narrow the right choice. For G78-15 and H78-15, the availability of radial equivalents adds another layer to the decision.

The available sidewall styles for 1973 International Travelall 1010 tires are blackwall and wide whitewall. Those choices appear across the 700-15, G78-15, and H78-15 size range, though the exact style mix changes by size and tire series.

That makes sidewall style one of the biggest appearance decisions on this vehicle. A wide whitewall gives the Travelall a more dressed, period-style presentation, while a blackwall keeps a more work-oriented or truck-based look. Since sidewall treatment does not change the underlying need for the correct size and wheel match, it is best chosen after the fitment basics are settled rather than treated as the first step in selecting a tire.

Tires for the 1973 International Travelall 1010 are available from Firestone, BFGoodrich, Coker Classic, and STA. Brand availability varies by size, with 700-15 showing the broadest spread and the G78-15 and H78-15 sizes centering on Coker Classic and STA offerings.

Brand alone is not the whole decision on a vehicle like this, because the tire series and intended character matter just as much. Some choices lean toward classic passenger-style presentation with wide whitewalls, while others use truck-oriented series such as Traxion, Super Traxion, Super Transport, or Transport Highway. The better comparison is brand plus size, sidewall style, and wheel compatibility rather than picking a name first and trying to force the fitment afterward.

A period-style 1973 International Travelall 1010 usually starts with one of its primary bias-ply sizes rather than a modern metric radial. The right choice among 700-15, G78-15, and H78-15 depends on the vehicle's existing wheel setup and the look being pursued, with available products ranging from wide whitewall classic designs to more truck-oriented blackwall patterns.

That approach keeps the size language and construction style in line with the Travelall's era, which is often important on a restoration-minded vehicle. Exact originality can still vary by how the truck was equipped when new, so buyers concerned with highly specific presentation should compare their vehicle against marque references, period photos, or build-related documentation. Once that baseline is clear, the sidewall and series choice becomes much easier.

Tire construction changes more than road feel on a restored 1973 International Travelall 1010; it also changes how the vehicle presents visually. The primary fitments are bias-ply, so staying with bias-ply construction maintains the older sizing formats and supports a distinctly vintage stance, especially when paired with a wide whitewall or traditional blackwall design.

A radial alternative can still be worth considering, particularly for G78-15 and H78-15, but it should be chosen with the understanding that the visual effect may differ from a classic bias-ply tire. Bias-look radials are one way to bridge that gap without treating them as the same thing as a true bias-ply tire. On a restoration project, appearance goals should be settled before construction is changed.

Yes, modifications can affect tire fitment on a 1973 International Travelall 1010 even when the tire size itself is correct on paper. Aftermarket wheels, different wheel widths, suspension changes, replacement springs, or body alterations can all change how 700-15, G78-15, or H78-15 tires sit in the wheel opening and clear surrounding components.

That is especially important on an older truck-based wagon because many have seen practical changes over the years. A Travelall with non-original wheels may still use a 15-inch rim but require a different width range than expected, and a lowered or lifted suspension can affect steering and fender clearance. Measuring the actual vehicle before choosing a tire is more reliable than assuming that every original-size reference still matches a modified setup.

Before driving a 1973 International Travelall 1010 on new tires, inspect the wheels, lug hardware, valve stems, and overall wheel condition along with the new tire fitment itself. It also helps to confirm that the tire size matches the wheel and that inflation is set appropriately for the tire being used.

A short, careful initial drive is wise on any collector-era vehicle after tire installation. During that check, pay attention to steering clearance, any rubbing at full lock, and signs that the vehicle has uneven suspension or alignment issues that could affect the new tires. Since the Travelall may have old brake, steering, or suspension components even when the tires are fresh, road readiness should be judged as a whole-vehicle condition, not a tire-only change.

Collector-use tires on a 1973 International Travelall 1010 should be maintained with regular pressure checks, visual inspections, and attention to age-related condition rather than tread depth alone. Look for cracking, cuts, bulges, flat spotting after storage, and any steady air loss, especially on a vehicle that sits for long periods.

Storage habits matter almost as much as road miles on a vintage Travelall. Keeping the vehicle away from long exposure to sunlight, excess heat, standing moisture, and ozone sources helps preserve the tire casing and sidewalls over time. It is also smart to inspect the spare and to recheck the tires before longer drives, since a truck-based collector vehicle can spend months parked and then suddenly be asked to carry passengers and cargo again.
