1975 International Travelall 150 Tires

The 1975 International Travelall 150 uses four primary tire sizes: H78-15, HR78-15, 700-15, and L78-15. The correct size depends on the exact configuration. Base models use H78-15 bias-ply or HR78-15 radial fitments, while 4x4 versions use 700-15, H78-15, or L78-15 bias-ply tires, all on 15-inch rims.

That means the first step is identifying whether the truck is a Base model or a 4x4, then checking the wheels actually on the vehicle. Many Travelalls have seen wheel or suspension changes over time, so matching the tire to the current setup matters just as much as matching it to the original size family.

The primary tire sizes used on the 1975 International Travelall 150 all share a 15-inch rim diameter. That includes H78-15, HR78-15, 700-15, and L78-15, so the basic wheel diameter stays consistent even though the tire sizes and construction types vary by configuration.

A shared 15-inch diameter does not mean every tire option belongs on every wheel. Wheel width still matters, especially when moving among 700-15, H78-15, and L78-15 sizes or considering a radial alternative. It is smart to verify the actual wheel width and overall clearance before settling on a specific tire.

No. The 1975 International Travelall 150 has sub-model variation in tire fitment. Base versions use H78-15 and HR78-15, while 4x4 configurations use 700-15, H78-15, and L78-15, all on 15-inch wheels but not as one universal size across every truck.

That variation makes the exact sub-model more important than the model name alone. A buyer looking at a Base truck may be deciding between bias-ply and radial in one size family, while a 4x4 owner may need to sort through several bias-ply sizes and more truck-oriented tire series before making a final choice.

H78-15 is a bias-ply tire size on the 1975 International Travelall 150. It uses the vintage alphanumeric sizing system, and on this vehicle it appears as a primary bias-ply fitment rather than a radial one. The radial version in this format is HR78-15, where the R identifies radial construction.

That distinction matters because bias-ply and radial tires change both appearance and setup considerations. If the truck currently has H78-15, staying with a bias-ply keeps the traditional sizing format intact. Any move toward a radial alternative should include a check of wheel width, overall dimensions, and clearance at full steering travel.

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. Those options cover several sizing conventions while staying within the same general comparison range for an H78-15 application.

The practical difference is that the choices vary in format and profile style, not just construction. The recommended rim-width range for these H78-15 radial equivalents is 6-8 inches, so the wheel should be checked before conversion. Clearance around suspension, fenders, and steering components also deserves attention before choosing any of the alternatives.

Start by confirming the truck's exact primary tire size, wheel diameter, and wheel width, then compare any radial equivalent to the current setup. On this Travelall, H78-15 and L78-15 have named radial-equivalent paths, but those alternatives remain just that: alternatives, not automatic substitutions for every truck and wheel combination.

A careful conversion also includes checking steering clearance, fender clearance, suspension condition, and the vehicle's actual stance after any past modifications. Owners of Base models should note that HR78-15 is already a primary radial fitment in some configurations, while 4x4 owners may need to be more deliberate about size family and truck-use requirements.

Start with the correct primary size for the exact truck: H78-15, HR78-15, 700-15, or L78-15. After that, the key factors are construction type, wheel compatibility, sidewall appearance, and whether the tire is aimed at a more passenger-style presentation or a more truck-oriented duty profile.

A Base Travelall owner may be comparing bias-ply versus radial in the vintage alphanumeric range, while a 4x4 owner may be sorting through 700-15 and L78-15 utility-focused products. Looking at rim-width guidance, load capacity wording, and the truck's intended use helps narrow the choices without reducing the decision to style alone.

Sidewall choices for the 1975 International Travelall 150 include blackwall, wide whitewall, narrow whitewall, and dual-white-stripe depending on size. H78-15 appears in blackwall and wide whitewall, 700-15 in blackwall and wide whitewall, and L78-15 in blackwall, wide whitewall, narrow whitewall, and dual-white-stripe form.

That variety gives the Travelall owner room to tailor the truck's look without changing the basic fitment category. A whitewall or stripe can create a more restoration-oriented presentation, while blackwall truck-series tires lean more toward utility character. The best approach is to choose the sidewall after the correct size and wheel compatibility are already settled.

The 1975 International Travelall 150 has tire options from Coker Classic, Firestone, BFGoodrich, and STA across its supported sizes. Those brands appear in different combinations depending on whether the truck uses H78-15, 700-15, or L78-15, with some tires leaning toward classic passenger styling and others toward truck service.

Brand choice is most useful when paired with size, sidewall style, and tire series rather than treated as the only decision point. A Firestone or BFGoodrich whitewall in 700-15 creates a different presentation than an STA truck-series blackwall, and L78-15 adds even more visual variation through several sidewall treatments.

A period-style 1975 International Travelall 150 usually starts with keeping the correct primary size and the visual character that suits the truck's configuration. That may mean an H78-15, 700-15, or L78-15 bias-ply tire, with the final look shaped by blackwall, wide whitewall, narrow whitewall, or dual-white-stripe presentation.

The best period-style choice depends on whether the goal is a family-wagon look, a more upscale road-going presentation, or a utility-minded 4x4 stance. When exact originality matters, the tire should be checked against vehicle-specific historical references and the truck's actual wheel setup so appearance does not override proper fitment.

Tire construction changes the visual character of a restored 1975 International Travelall 150 as much as the sidewall treatment does. Bias-ply tires preserve the traditional vintage sizing language used by H78-15, 700-15, and L78-15, while radial choices such as HR78-15 or named radial equivalents can give the truck a more modern visual stance.

That does not make one approach universally right. A restoration-oriented owner may prefer the classic look of a bias-ply sidewall, while a driver-focused owner may want a radial format that still respects the truck's period proportions. Deciding early on appearance goals helps narrow the field before comparing specific tire series and sidewall styles.

Yes. Modifications can change tire fitment on a 1975 International Travelall 150 even when the truck still uses 15-inch wheels. Aftermarket wheels, altered wheel width, suspension lifts or lowering, and body or steering changes can all affect how H78-15, HR78-15, 700-15, or L78-15 tires sit and clear.

That is especially important on older utility vehicles that may have changed hands many times. A Travelall that now wears different wheels than it did years ago may need a closer look before ordering the same nominal size again. Checking wheel width, steering sweep, and fender room helps avoid choosing a tire on size code alone.

Before road use, inspect the wheel condition, valve stems, lug hardware, and overall tire inflation, then make sure the new tires clear suspension and bodywork through full steering travel. It is also wise to check alignment-related wear patterns, brake function, and whether the spare and road tires are in the same general fitment family.

A collector-era truck like a Travelall often spends time parked, so the rest of the running gear deserves attention too. Fresh tires cannot correct worn steering parts, tired springs, or wheel damage. A short local test drive and a second inspection for rub marks, air loss, or unusual behavior can catch issues early.

Tires on a 1975 International Travelall 150 should be maintained with regular pressure checks, visual inspections, and periodic review for cracking, bulges, cuts, uneven wear, or slow air loss. Vehicles that see occasional use need the same attention as daily drivers, especially because age and storage conditions can affect collector tires long before tread is worn.

Storage habits matter on a Travelall that spends long stretches indoors or under cover. Keeping the tires away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve them, and moving the vehicle occasionally can reduce prolonged flat-spotting. Any change in vibration, pull, or sidewall condition deserves prompt inspection before another drive.
