International Pickup 150 Tires

The International Pickup 150 uses two listed tire sizes for 1975: H78-15 and L78-15. Both are alphanumeric bias-ply sizes built for 15-inch wheels. H78-15 products are shown on 15-inch rims with recommended rim widths from 5.50 to 7.00 inches, while L78-15 products are shown on 15-inch rims with recommended rim widths from 5.50 to 8.00 inches. The available products span passenger-style classic bias-ply tires and heavier-duty truck-oriented bias-ply designs.

The practical difference is that the truck may not use the same tire size across every configuration even though the model year is the same. Check the size currently on the truck, confirm the wheel diameter is 15 inches, and compare wheel width before selecting between H78-15 and L78-15. If the truck is being restored for period appearance, the sidewall style matters too. If it is expected to carry more weight or retain a more commercial look, the truck-oriented offerings may be the more appropriate direction.

H78-15 is an alphanumeric bias-ply tire size used on the 1975 International Pickup 150. The H identifies the tire’s general width and load class family, the 78 is the series designation used in this older sizing system, and the 15 indicates the required wheel diameter in inches. Every H78-15 product here is a bias-ply tire for a 15-inch rim, with listed rim-width recommendations of 5.50 to 7.00 inches.

That means H78-15 is not just a cosmetic variation of L78-15. It points to a different size class, so the right choice depends on the wheel and the truck’s specific configuration. If your International Pickup 150 still has its original wheels, verify the stamped wheel size and compare proportions with period photos or literature. That extra step matters because alphanumeric sizing is less intuitive to modern buyers than metric tire sizing, and a letter change can represent a meaningful change in section width and overall stance.

The 1975 International Pickup 150 has two listed tire sizes because the model year was offered with more than one tire specification. In this case, both listed sizes use the same 15-inch rim diameter and both are bias-ply constructions, so the split is not a wheel-diameter change or a radial-versus-bias difference. The distinction is a size-class variation within the same model year, which usually points to differences in configuration, duty use, or wheel and tire package selection.

That is why the year alone is not enough to choose a tire for an International Pickup 150. Compare the truck’s existing tire size, the wheel width, and the look you are trying to preserve. A narrower H78-15 and a larger L78-15 will not present the same way on the truck even though both fit a 15-inch wheel. If originality matters, use period references tied to your exact truck rather than assuming every 1975 Pickup 150 left the factory on the same tire.

The listed International Pickup 150 tires are all bias-ply alphanumeric sizes, and the available products do not indicate a tubeless construction. For that reason, a tube is required with the H78-15 and L78-15 tires shown here. That guidance follows the construction and sizing style of these period-type bias-ply products rather than modern radial practice.

Tube use matters because a truck can have a correct tire size but still be set up improperly if the wheel, flap, or tube arrangement is wrong. Before fitting new tires to an International Pickup 150, inspect the wheel for corrosion, rough bead seats, and valve-hole condition, and make sure the tube matches the tire size and wheel. That is especially important on a collector truck that may have sat for long periods, where wheel condition can be as important as tire condition.

The most direct way to confirm the correct tire size for a 1975 International Pickup 150 is to verify whether the truck is using H78-15 or L78-15 and then make sure the wheel is a 15-inch rim. Both sizes are listed for the same model year, so the year by itself does not settle the question. H78-15 products are intended for 15-inch rims and list 5.50 to 7.00 inch wheel widths, while L78-15 products are also for 15-inch rims and list 5.50 to 8.00 inch wheel widths.

Start with the sidewall marking on the tire if the truck still has a known-correct set. Then verify the wheel diameter and width on the actual wheel, especially if the truck has changed hands or been restored before. If the old tires are missing, compare the truck against factory literature, build information, or an International specialist who knows Pickup 150 configurations. That process matters more on a single-year listing with multiple sizes than it does on a model line that carried one size throughout production.

International Pickup 150 tires are offered here in several sidewall styles depending on size and series. H78-15 is available as wide whitewall and blackwall, while L78-15 adds blackwall, wide whitewall, narrow whitewall, and dual-white-stripe choices. That creates a broad spread from work-truck appearance to more stylized period presentation, even though all of the listed tires remain bias-ply constructions.

For a restoration-minded truck, blackwall is usually the most straightforward choice when the goal is a practical pickup appearance. Whitewall and stripe treatments change the character significantly and are often chosen for a more personalized or show-oriented presentation. The important thing is to separate appearance from fitment: sidewall style does not change the required wheel diameter or the core size choice. Decide on H78-15 versus L78-15 first, then select the sidewall treatment that best matches how your International Pickup 150 is being preserved.

Three brands are represented for International Pickup 150 tire sizes here: Coker Classic, BFGoodrich, and STA. Coker Classic appears in both H78-15 and L78-15, BFGoodrich appears in L78-15, and STA appears in both sizes with truck-oriented blackwall offerings. The result is a mix of period-style passenger bias-ply tires and more utility-focused designs for buyers who want a different look or duty emphasis.

Brand choice should come after the fitment decision, not before it. Once the truck’s correct size is settled, compare the available sidewall treatments, load ratings where shown, and overall character of each offering. A whitewall Coker Classic or BFGoodrich will suit a more styled presentation, while STA Traxion-family products lean more toward truck use and visual toughness. Matching the brand and series to the role of your International Pickup 150 usually leads to a better result than simply choosing by name alone.

The International Pickup 150 is represented here by four tire series: Coker Classic Bias Ply, Silvertown Classic Bias Ply, Traxion, and Super Traxion, with Transport Highway also listed as a distinct STA highway-oriented offering. Coker Classic Bias Ply and Silvertown Classic Bias Ply are period-style passenger tire series, while Traxion, Super Traxion, and Transport Highway sit in the truck and utility side of the range. All of them are bias-ply constructions, but they differ in sidewall presentation, intended character, and in some cases listed load capacity.

That means the best series depends on how the International Pickup 150 is being used and presented. A truck restored with an emphasis on appearance may favor one of the classic bias-ply series with whitewall or stripe options, while a more functional or commercial-looking build may be better matched to the STA truck lines. Compare the tire size first, then the series family, then the sidewall style. That order keeps fitment, function, and appearance from getting mixed together during the selection process.

An International Pickup 150 should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and major temperature swings. Keep the tires inflated to a stable storage pressure appropriate to the tire and the truck’s weight, and avoid leaving the truck parked for long periods on damp surfaces or bare earth. Collector trucks that sit for extended periods benefit from clean wheels, clean sidewalls, and a storage environment that does not stress the rubber.

Long stationary periods can create flat-spotting and can also hide slow air loss, especially on tube-type bias-ply tires. Moving the truck occasionally, rolling it a short distance, or using stands according to a restorer’s preferred practice can help reduce concentrated load in one spot. It is also wise to inspect for cracks around the bead area and valve stems before the truck goes back into service. Good storage habits matter because even a lightly used International Pickup 150 can age its tires out long before it wears them out.

Tires on an International Pickup 150 should be inspected before each drive if the truck is used occasionally, and more thoroughly at regular seasonal intervals. On a bias-ply collector-truck tire, inspection should include air pressure, tread and sidewall cracking, bulges, irregular wear, bead condition, and valve stem condition. Because these trucks are often driven less than modern vehicles, age-related issues can develop without showing up first as tread wear.

A practical routine is to give the truck a quick visual check before every outing and a deeper inspection whenever it is cleaned, serviced, or prepared for an event. If the truck carries load, sits for long stretches, or uses older wheels, inspections become even more important. Catching a tube problem, sidewall crack, or wheel issue early is far easier than dealing with a failure after the truck is already on the road. Consistent inspection is one of the simplest ways to protect an International Pickup 150 and its occupants.

Tires on an International Pickup 150 should be replaced when age, cracking, hardening, bulges, impact damage, or repeated air-loss issues appear, even if the tread still looks usable. Collector vehicles often age tires out before they wear them down, and bias-ply constructions can look presentable while still losing the flexibility needed for dependable road service. A tire that has sat under load for years or shows separation, severe weather checking, or bead damage has reached the point where replacement should take priority over remaining tread depth.

That rule is especially important on a truck that may alternate between storage and occasional use. Replacement timing should be guided by condition, age, and inspection by a tire professional familiar with collector vehicles rather than tread alone. If the truck has an older spare, treat it with the same caution as the road tires. The safest approach with an International Pickup 150 is to think of tire condition as part of the vehicle’s overall mechanical readiness, not as a separate cosmetic issue.

The International Pickup 150 is associated here with H78-15 and L78-15 tire sizes, both in bias-ply construction on 15-inch rims. The available series include Coker Classic Bias Ply, Silvertown Classic Bias Ply, Traxion, Super Traxion, and Transport Highway, which shows that more than one period-appropriate style exists within the listed size range. That does not automatically make every series correct for every individual truck, because appearance and duty emphasis can vary even within a single model year.

For an authenticity-focused restoration, the size is the first piece to settle and the exact series is the second. Use factory literature, period photographs, or International marque resources to determine whether your specific truck would have presented more like a passenger-style pickup or a more work-oriented configuration. Once that is clear, you can narrow the choice among blackwall, whitewall, or stripe treatments without drifting away from the correct size family. Getting both the size and the visual character right adds credibility to an International Pickup 150 restoration.

Correct tire fitment can affect both the presentation and the perceived quality of an International Pickup 150, especially when the truck is being judged or evaluated by knowledgeable collectors. The right size, proper overall proportions, and an era-appropriate sidewall style help the truck sit correctly and support the rest of the restoration work. Even on a practical pickup, tires are one of the first visual cues enthusiasts notice because they frame the stance and utility character of the vehicle.

That does not mean every restored International Pickup 150 must wear the same sidewall treatment or tire series. It does mean the choice should be intentional and consistent with the truck’s build story, whether that is factory-style restoration, preserved original, or period-custom presentation. Marque clubs and experienced International restorers are good reference points when judging standards matter. Tire fitment that looks too modern, too wide, or mismatched to the truck’s purpose can distract from otherwise careful restoration work.

International Pickup 150 tires are available here in blackwall, narrow whitewall, wide whitewall, and dual-white-stripe form depending on size and series. Blackwall is the most work-truck-oriented presentation, while whitewall and stripe styles create a more dressed appearance that suits certain restored or personalized builds. Because both H78-15 and L78-15 appear for 1975, sidewall choice should always follow confirmation of the actual tire size rather than lead the decision.

For a restoration, the correct sidewall style is the one that matches how your specific International Pickup 150 was equipped and how you intend to present it. A truck restored as a straightforward utility model will usually look most convincing on blackwalls, while a more upscale or customized period look may justify whitewall or stripe treatments. Period photographs and original sales material are useful tie-breakers when more than one look seems plausible. The best result is a tire that supports both the truck’s proportions and its historical character.

These International Pickup 150 tires can be appropriate for public-road use when they are new, correctly fitted, properly inflated, and matched to a sound vehicle. The available offerings here are all bias-ply tires, so they deliver a period-correct driving feel rather than modern radial behavior. Safety depends not just on size choice, but also on wheel condition, tube installation, suspension health, steering condition, brake performance, and whether the selected tire matches how the truck is actually used.

That means a roadworthy International Pickup 150 starts with the whole vehicle, not the tire alone. Before regular driving, inspect the wheels, confirm the tire size and load suitability, and make sure the truck tracks, stops, and steers as it should. Bias-ply tires can serve well on a collector truck, but they ask for realistic expectations and a well-sorted chassis. If the truck still has older components or long periods of storage behind it, a thorough mechanical review should come before any extended road use.

Before driving an International Pickup 150, check tire pressure, visible sidewall condition, tread condition, valve stems, and any signs of air loss around the wheel and bead area. Since the listed tires are bias-ply and tube-required, you should also be alert for vibration, pull, or heat buildup that can point to a mounting, balance, or tube issue. On an older truck, tire inspection should be paired with a quick look at brakes, steering linkage, wheel bearings, and lug hardware.

A short pre-drive routine makes a real difference on a collector pickup because problems often appear after storage rather than after high mileage. If the International Pickup 150 has been parked for months, take the first drive slowly and listen for changes in feel as the tires begin to work. Recheck pressure after the truck has settled back into use. That simple habit helps catch slow leaks, wheel issues, or age-related tire concerns before they turn into a roadside problem.

An International Pickup 150 on original-style bias-ply tires should be driven at sensible, moderate speeds that respect both the tire design and the age of the vehicle. Bias-ply construction does not behave like a modern highway radial, and an older truck’s steering, braking, and suspension systems also shape what feels stable and appropriate. Even when the tires are new, the truck should be treated as a classic vehicle with period manners rather than a modern pickup.

The practical approach is to build speed gradually and keep the truck within a range where it feels settled, tracks cleanly, and stops confidently. If the International Pickup 150 is carrying load, that matters even more, because tire pressure, heat, and handling all become more critical. Any shimmy, wandering, or overheating is a signal to slow down and inspect the setup rather than push through it. Matching speed to the truck’s condition is just as important as choosing the right tire size.
