1974 International Travelall 100 Tires

The 1974 International Travelall 100 uses four primary tire sizes: 700-15, H78-15, L78-15, and H70-15. All are bias-ply fitments for 15-inch wheels, but they do not apply uniformly across every version of the vehicle. The 4x4 uses 700-15, H78-15, and L78-15, while the Base model uses H70-15 and H78-15.

That means the first step is confirming the exact sub-model and then checking the actual wheel setup on the Travelall. Many surviving trucks and wagons have had wheel or tire changes over time, so the right choice is the size that matches both the vehicle configuration and the wheel dimensions currently on it.

The primary tire fitments for a 1974 International Travelall 100 are all built around a 15-inch rim diameter. That applies to 700-15, H78-15, L78-15, and H70-15. Even though the tire sizes differ by sub-model, the wheel diameter remains consistent across the listed fitments.

Rim diameter is only one part of fitment, so it is still important to confirm wheel width before selecting a tire. Product specifications within these sizes use different rim-width ranges, and that can influence which bias-ply tire or radial equivalent makes the most sense for the way the Travelall is equipped.

No, the 1974 International Travelall 100 does not use the same tire size across all sub-models. The 4x4 uses 700-15, H78-15, and L78-15, while the Base model uses H70-15 and H78-15. H78-15 is the shared size, but the other fitments vary by version.

That difference matters because choosing by model name alone can lead to the wrong tire. A buyer should verify whether the vehicle is a Base or 4x4, then confirm the existing wheel and tire combination before deciding between classic bias-ply options, truck-style tread patterns, or any radial-equivalent alternatives tied to the applicable primary size.

H78-15 is a bias-ply primary tire size for the 1974 International Travelall 100. It uses the vintage alphanumeric sizing system rather than a modern metric radial format, and it appears as one of the original-style 15-inch fitments used on this vehicle.

That distinction matters because keeping H78-15 in bias-ply form preserves the traditional construction and period-style presentation of the Travelall. A radial can be considered through an equivalent size, but the wheel width, overall dimensions, and vehicle clearance should be checked carefully before changing construction on a heavy full-size utility vehicle.

Radial equivalents for H78-15 include 215R15 as an 80-series metric radial, P225/75R15 as a 75-series P-metric radial, P235/70R15 as a 70-series P-metric radial, and 760R15 as a bias-look radial. These are alternative radial formats associated with the H78-15 primary size rather than additional original bias-ply fitments.

The practical difference is that these options move from traditional metric radial sizing to lower-profile P-metric sizing, while 760R15 is intended to retain a more vintage visual character. A 6-8 inch recommended rim-width range is associated with this conversion path, and wheel compatibility plus body and steering clearance should be reviewed before making the change.

Start by confirming which primary size the Travelall actually uses, because radial equivalents differ between H78-15, H70-15, and L78-15. The wheel diameter is 15 inches, but wheel width, the selected equivalent size, and the intended use of the vehicle all matter before moving from a bias-ply tire to a radial alternative.

A careful conversion also includes checking the actual wheel, suspension condition, steering clearance, and fender clearance on the vehicle as it sits today. Since many Travelalls have seen repairs, upgrades, or wheel changes over the years, the safest approach is to compare the intended radial equivalent against the current setup rather than assuming every 15-inch option behaves the same.

The main factors are the correct primary size for the sub-model, the 15-inch wheel setup, and the role the vehicle plays today. A 4x4 may point you toward 700-15, H78-15, or L78-15, while a Base model may use H70-15 or H78-15. After size is confirmed, construction, sidewall appearance, and tread style become the real decision points.

A restoration-oriented Travelall may call for a classic whitewall or traditional blackwall bias-ply look, while a utility-minded vehicle may lean toward truck-style tread series. Rim-width specifications and load figures are also worth comparing, especially on a large wagon-bodied truck where appearance, carrying capacity, and the actual wheel in use all influence the final choice.

Sidewall choices for the 1974 International Travelall 100 include blackwall, wide whitewall, narrow whitewall, and dual-white-stripe depending on the tire size selected. Those appearance options are not spread evenly across every size, so the exact sidewall treatments available change with the fitment you are shopping.

That makes sidewall selection a second-step decision after confirming the proper size for the sub-model and wheel. A blackwall often suits a more truck-oriented presentation, while whitewall and stripe styles can shift the Travelall toward a more restoration-minded look without changing the fact that the underlying primary fitments remain vintage 15-inch bias-ply sizes.

Available brands for 1974 International Travelall 100 tire sizes include Firestone, BFGoodrich, Coker Classic, and STA. The brand mix changes by size, with some fitments leaning toward classic passenger-style offerings and others adding truck-oriented patterns that better suit the Travelall’s heavier-duty character.

Brand alone should not decide the purchase. It makes more sense to narrow the correct size first, then compare the available tire series, sidewall treatments, rim-width specifications, and load figures within that size. That approach keeps the selection tied to the vehicle’s actual fitment and the type of appearance or road use the owner wants.

A period-style 1974 International Travelall 100 starts with the correct primary bias-ply size for the exact sub-model, then moves to the visual character of the tire. Blackwall, wide whitewall, narrow whitewall, and dual-white-stripe options are available in certain sizes, and truck-oriented tread series are also part of the mix for more utility-focused presentations.

That means appearance should be chosen after fitment, not before it. If the goal is a historically convincing restoration, the tire should suit both the Travelall’s stance and the vehicle’s intended personality, and buyers pursuing exact originality should compare their choice against marque literature, surviving examples, or model-specific restoration references.

Tire construction has a noticeable effect on the look of a restored 1974 International Travelall 100 because its primary fitments are bias-ply tires in vintage numeric and alphanumeric sizes. A bias-ply tire tends to preserve the traditional visual character associated with older full-size utility vehicles, especially when paired with period-style blackwall or whitewall sidewall treatments.

Switching to a radial equivalent can change the visual impression even when the wheel diameter remains the same. Owners who want a more traditional appearance but still want to explore radial construction often look closely at bias-look radial options, while those focused on restoration presentation usually begin by keeping the original-style sizing format intact.

Yes, modifications can affect tire fitment on a 1974 International Travelall 100. Even when the correct primary size is known, aftermarket wheels, different wheel widths, suspension changes, ride-height changes, or body alterations can influence how a tire sits and clears the vehicle under steering and load.

That is especially important on a large vehicle that may have seen decades of repairs or upgrades. A Travelall with non-original wheels or suspension parts should be measured as it currently sits, with attention paid to wheel diameter, wheel width, and clearance at the fenders and steering components before any bias-ply replacement or radial-equivalent conversion is finalized.

Before putting a 1974 International Travelall 100 back on the road, inspect the wheels, lug hardware, valve stems, and the general condition of the suspension and steering components. It also makes sense to confirm that the new tires match the intended size and wheel dimensions, especially on a vehicle where the wheel setup may have changed over time.

Tire condition checks should include pressure, visible damage, bead seating, and clearance during full steering travel. A slow road test can help reveal rubbing, pulling, or vibration before longer use. On an older full-size utility vehicle, fresh tires are only one part of the equation; the supporting chassis and wheel hardware should be in equally roadworthy shape.

Tires on a 1974 International Travelall 100 should be maintained with regular pressure checks, visual inspections, and periodic review of tread and sidewall condition. Collector vehicles that are driven less often still need attention, because age, storage conditions, and long stationary periods can affect tire condition even when tread wear looks minimal.

A good routine includes checking for cracking, bulges, cuts, and air loss, while also watching for uneven wear that may point to alignment or suspension issues. Storage matters as well, since prolonged exposure to heat, sunlight, and moisture can shorten tire life. Consistent inspection is particularly important on an older Travelall expected to carry passengers and cargo.
