International Scout Tires

International Scout uses four listed tire sizes across the years covered here: E78-15 for 1971 through 1973, and F78-15, G78-15, and H78-15 for 1971 through 1974, with 1974 showing F78-15, G78-15, and H78-15. Every listed size uses a 15-inch rim. The available product range shown here is concentrated in G78-15 and H78-15, both in bias-ply construction.

The practical step is to match the size on the vehicle itself rather than assume every International Scout used the same tire. If the sidewall marking is missing or the vehicle is under restoration, compare the year listing with the wheel setup already on the truck and verify which width class it was built to carry before moving ahead.

G78-15 is an older alphanumeric bias-ply size used on International Scout models from 1971 through 1974 in the fitment range shown here. The G identifies the tire's width class, the 78 is the aspect-series designation used in period sizing, and the 15 indicates the rim diameter in inches. It is not a modern metric radial size, even though it may look similar at a glance.

That matters because a G78-15 should be matched to the correct 15-inch wheel and period-correct bias-ply application. If your Scout already has modern tires, compare the overall intended stance and wheel width carefully before substituting anything, especially on a restoration where appearance and steering feel both matter.

A 1972 International Scout can show E78-15, F78-15, G78-15, and H78-15 because more than one configuration was fitted within that model year. All four sizes use the same 15-inch rim diameter, so the split is not a wheel-diameter change. It reflects variation within the model range rather than a single one-size-fits-all tire specification.

When a year shows several sizes, the safest approach is to identify the specific setup on the truck instead of selecting only by model year. Check the existing tire marking, verify the wheel width if known, and compare the overall look and intended use of the Scout, especially if you are deciding between a passenger-style whitewall and a more truck-oriented tread.

The listed International Scout sizes are alphanumeric bias-ply sizes without radial construction, and the available products shown for G78-15 and H78-15 are bias-ply tires. For these older bias-ply fitments, a tube is required. That applies to the listed alphanumeric sizes in this fitment group rather than to a modern tubeless radial conversion.

Tube use affects installation details, wheel condition, and long-term air retention on a collector vehicle. If the Scout has older wheels, inspect the wheel surfaces and hardware carefully during mounting so the tube is not compromised by corrosion, rough edges, or incorrect components.

A 1973 International Scout can use E78-15, F78-15, G78-15, or H78-15 in the year range covered here, so the correct choice depends on the specific configuration. All are 15-inch sizes, but they differ in width class. A quick year match alone is not enough when one year carries four possible fitments.

Start with the size marked on the existing tire if the truck still has a known-correct setup. If the Scout is being restored or has changed wheels over time, compare the year listing with the wheel dimensions and the stance you are trying to preserve so the replacement remains consistent with the truck's intended look and use.

International Scout tires in the available product range include both wide whitewall and blackwall sidewall styles. The G78-15 and H78-15 offerings include Coker Classic wide whitewalls and STA blackwall truck-style tires. That gives buyers a visible choice between a more passenger-car presentation and a more utility-oriented appearance.

Sidewall style should match the character of the specific Scout you are building. A whitewall can suit a more street-oriented or period-flavored presentation, while a blackwall traction-style tire usually looks more at home on a working, off-road, or truck-focused build.

Two brands appear in the current International Scout product range: Coker Classic and STA. Coker Classic covers the passenger-style bias-ply options with wide whitewall treatments in G78-15 and H78-15, while STA covers blackwall truck-oriented tread patterns in those same sizes. Both are presented in bias-ply construction.

Brand choice should follow the role of the vehicle, not just the name on the sidewall. If the Scout is being restored with attention to period style, the whitewall offerings may make sense, while a more rugged-use appearance may point you toward the STA options.

International Scout products here appear in three tire series: Coker Classic Bias Ply, Super Traxion, and Traxion. Coker Classic Bias Ply is the passenger-style series represented by wide whitewall tires, while Super Traxion and Traxion are truck-oriented series offered as blackwalls. All three are bias-ply, but they differ in appearance and intended character.

That distinction matters because the tire contributes heavily to how a Scout looks and feels as a finished vehicle. A street-focused restoration and a utility-minded 4x4 build can both be period-appropriate, but they usually call for different tread and sidewall presentations even when the nominal size is the same.

An International Scout should be stored on a clean, dry surface away from direct sunlight, ozone sources, and long periods of heat exposure. Tire pressure should be checked before storage and maintained so the casing is not left underinflated. Bias-ply tires especially benefit from a stable environment because they can develop flat spotting when left stationary for long stretches.

If the Scout will sit for months at a time, move it periodically or take steps to reduce constant load on one patch of the tire. Good storage habits preserve both appearance and drivability, which is especially important on collector 4x4s that may only see seasonal road use.

Tires on an International Scout should be inspected before regular driving and again after any long storage period. Look for air loss, sidewall cracking, irregular wear, impact damage, and signs that the tube or casing may be stressed. Bias-ply tires on older utility vehicles deserve close routine attention because storage time can age them as much as mileage does.

A quick inspection before each outing is a good habit, especially if the truck sees occasional use rather than daily service. Collector vehicles often accumulate age without accumulating miles, so visual checks and pressure checks matter more than tread depth alone.

International Scout tires should be replaced when age, cracking, casing fatigue, persistent air loss, or damage makes continued use questionable, even if tread remains. Tread depth by itself is not a complete measure on a collector vehicle because the tire may age out long before it wears out. Older bias-ply tires can look serviceable while the internal condition is no longer suitable for road duty.

The right approach is to judge tires by age and condition as much as by appearance. If the Scout has spent years parked, have the tires evaluated during routine service so you are not relying on old rubber simply because the tread still looks substantial.

International Scout appears here with four period-size options: E78-15, F78-15, G78-15, and H78-15, all in 15-inch sizing. The available tire series include Coker Classic Bias Ply, Super Traxion, and Traxion, which shows that more than one style of replacement tire suits the range. The exact original fit for a specific Scout depends on the year and configuration rather than the model name alone.

For a careful restoration, use the year listing as the first filter and then compare against surviving factory information for your truck. That is especially important when one year carries several size options, because concours accuracy often comes down to matching the precise configuration rather than choosing any period-looking tire.

Correct tire fitment can affect both the appearance and the judged authenticity of an International Scout. Size, sidewall treatment, and tread character all change how the truck sits and whether it reads as a street-oriented restoration or a utility-spec 4x4. On a vehicle from this era, judges and experienced enthusiasts usually notice tire presentation immediately.

Matching the right size and sidewall style to the truck's intended configuration helps preserve period character and can support the overall credibility of the restoration. If the Scout is being prepared for marque judging, compare your choice against accepted club standards and period images before final installation.

International Scout tire options here include wide whitewall and blackwall sidewall styles. Either can be appropriate depending on the exact vehicle character being restored, since the available range includes both passenger-style and truck-style presentations. The sidewall is part of the visual identity of the tire, not just a cosmetic detail.

A street-focused Scout often looks most natural with a period whitewall, while a work-oriented or off-road-themed Scout generally suits a blackwall traction tire better. The best choice is the one that matches the year, trim intent, and overall restoration philosophy of the specific truck.

Bias-ply tires in the listed International Scout sizes can be appropriate for public-road use when they are new, correctly installed, properly inflated, and matched to a sound vehicle. The available G78-15 and H78-15 products are fresh-production style tires rather than modern high-speed performance radials, so they should be treated as period-type equipment. Their intended character is vintage driving, not contemporary SUV handling.

Road safety depends on the complete condition of the Scout as much as the tire itself. Before regular driving, make sure the steering, suspension, brakes, wheel condition, and alignment are all in good order so the tire is not being asked to compensate for mechanical issues.

Before driving an International Scout, check tire pressure, visible sidewall condition, tread condition, wheel security, and any signs of tube-related air loss. On a collector 4x4, it is also wise to look at steering play, brake feel, and whether the truck has sat long enough to develop flat spots. Those checks matter even more with bias-ply tires, which communicate changes in condition differently than modern radials.

A short walkaround can prevent most avoidable problems. If the Scout feels unsettled, wanders more than expected, or shows vibration that was not present before storage, stop and inspect the tires and wheels before continuing.

An International Scout on period-type bias-ply tires should be driven at moderate speeds that suit both the tire construction and the vehicle's overall vintage chassis behavior. Even when the size is correct, a bias-ply tire does not deliver the same high-speed stability or emergency-response feel as a modern radial. The truck's age and condition should guide your pace more than modern traffic expectations.

The sensible approach is to build speed gradually and evaluate how the Scout tracks, steers, and brakes. If the truck is newly restored or newly fitted with tires, keep early road use conservative until everything has been checked under real driving conditions.
