International Pickup 100 Tires

International Pickup 100 uses three listed tire sizes for 1974: G78-15, H70-15, and H78-15. G78-15 and H78-15 both have available products built for 15-inch rims, with G78-15 fitting 5.00 to 7.00 inch rim widths and H78-15 fitting 5.50 to 7.00 inch rim widths. All listed products for those available sizes are bias-ply construction.

The practical takeaway is that model year alone is not enough to choose correctly for an International Pickup 100. Start by reading the size on the tire already on the truck, then confirm the wheel diameter and rim width before moving to sidewall style or tread preference. If the truck has been changed over the years, compare what is on the vehicle against original references for that specific configuration.

G78-15 is an older alphanumeric bias-ply size used on the International Pickup 100. The G indicates the tire's width and load class within the period sizing system, the 78 identifies the aspect-series grouping, and the 15 is the rim diameter in inches. On the available products, that size fits a 15-inch wheel and is intended for rims from 5.00 to 7.00 inches wide.

That code matters because a G78-15 is not interchangeable by name with H70-15 or H78-15 even though all three fit 15-inch wheels. The letter and series number change the tire's proportions, which affects stance, clearance, and period appearance. For an International Pickup 100, match the exact code first, then choose the whitewall or blackwall style that suits the truck's restoration direction.

The 1974 International Pickup 100 has G78-15, H70-15, and H78-15 listed because more than one configuration used different tire proportions within the same model year. All three sizes share a 15-inch rim diameter, so the split is not a wheel-diameter change. Instead, the variation points to differences in setup such as trim level, body style, or intended duty.

That means a 1974 International Pickup 100 owner should not select a tire by year alone. Check the size currently on the truck, verify the wheel width, and compare the truck against factory literature, old service records, or marque knowledge if originality matters. That extra step helps avoid ending up with a tire that fits the rim but changes the truck's look or proportions.

The listed International Pickup 100 tire offerings are all bias-ply products in vintage alphanumeric sizing, and a tube is required. That applies to G78-15, H70-15, and H78-15 within this fitment group. Tube use is part of the normal service approach for these period-style bias-ply tires.

For a collector truck, tube fitment should be treated as part of the complete tire installation rather than an afterthought. The wheel condition matters too, especially if the truck still carries older rims that may have seen decades of service. When an International Pickup 100 is being returned to road use after long storage, inspect the wheels carefully so the tire-and-tube assembly starts with a sound foundation.

A 1974 International Pickup 100 can use G78-15, H70-15, or H78-15, so the correct tire begins with verifying the exact size specified for the truck's configuration. Reading the existing tire sidewall is the fastest starting point if the truck still carries an appropriate vintage-size tire. Wheel width is also important, since available G78-15 products fit 5.00 to 7.00 inch rims while available H78-15 products fit 5.50 to 7.00 inch rims.

If the truck has changed hands, been modified, or had wheels swapped, compare what is on it against old photographs, service paperwork, and factory literature for that specific setup. Doing that will tell you whether the current tire size is original to the truck or simply what fit at some point in its working life. For an International Pickup 100, that extra verification is especially useful because all listed choices share a 15-inch rim diameter but differ in proportion.

International Pickup 100 tires are offered here in two distinct sidewall styles: wide whitewall and blackwall. The wide whitewall choices appear in the Coker Classic bias-ply line, while the blackwall options appear in the STA truck-oriented offerings. That gives the International Pickup 100 both a more dressed restoration look and a more utilitarian period truck appearance.

Sidewall choice changes the character of the truck even when the basic size remains the same. A wide whitewall usually suits a more presentation-focused restoration or a pickup trimmed closer to passenger-car styling, while a blackwall tends to look more work-truck correct. Decide first what role your International Pickup 100 will play—showing, light touring, or utility-themed restoration—then choose the sidewall style that supports that look.

International Pickup 100 tires in this fitment group come from two brands: Coker Classic and STA. Coker Classic supplies bias-ply whitewall options in G78-15 and H78-15, while STA supplies blackwall truck-style choices in those same two sizes. The product mix therefore covers both restoration presentation and more work-oriented visual themes.

Brand selection should follow size confirmation rather than come first. Once the correct size is established for the International Pickup 100, the brand decision becomes a matter of appearance, intended use, and how closely you want the truck to reflect a passenger-style or truck-style period look. That sequence helps keep the purchase focused on fitment first and cosmetic preference second.

International Pickup 100 tires are represented here by three series: Coker Classic Bias Ply, Super Traxion, and Traxion. Coker Classic Bias Ply appears in wide whitewall form and suits a more traditional restoration appearance, while Super Traxion and Traxion are blackwall truck-oriented series from STA. All of them are bias-ply, so the main differences here are visual style and intended period character rather than a shift to radial construction.

Choosing among those series depends on how the truck is being presented. A more polished International Pickup 100 may look right on a whitewall Coker Classic tire, while a working-truck restoration often benefits from the more purposeful blackwall appearance of the STA lines. Once size is settled, comparing series is really about matching the tire's style to the truck's personality and use.

An International Pickup 100 should be stored on clean, properly inflated tires in a cool, dark, and dry space away from direct sunlight, ozone sources, and petroleum contamination. Bias-ply tires are especially prone to developing flat spotting when they sit in one position for long periods. Keeping the truck on a sound floor surface and moving it occasionally helps reduce localized stress on the casing.

Long-term storage habits have a visible effect on how an International Pickup 100 feels and looks when it returns to service. If the truck will sit for months at a time, many collectors use jack stands or reposition the vehicle periodically so the tire does not carry the same load point indefinitely. Clean storage conditions also help preserve whitewalls, blackwalls, and older wheel finishes alike.

Tires on an International Pickup 100 should be inspected before each drive and given a more thorough condition check several times خلال the driving season. Look for air loss, sidewall cracking, tread separation, impact damage, irregular wear, and signs that an older wheel or tube may be affecting the assembly. Bias-ply truck tires can spend long periods unused, so visible condition matters just as much as tread depth.

A quick walkaround before driving an International Pickup 100 often catches problems early, especially on a collector truck that may not be used every week. If the truck has been parked through a winter or a long restoration phase, inspect it more carefully before putting miles on it again. Regular checks are a simple way to protect both the tires and the bodywork of a vintage pickup.

An International Pickup 100 should have its tires replaced when age, cracking, hardening, bulges, separation, impact damage, or persistent air-loss issues appear, even if the tread still looks deep. Collector vehicles often age tires out long before they wear them out. A tire that looks acceptable at a glance can still be unsuitable for road use if the casing has deteriorated over time.

That is particularly important on an International Pickup 100 because many surviving trucks spend years parked between short outings. Replacement decisions should be guided by condition, age, and inspection results rather than tread alone. If an older period tire is still on the truck for authenticity reasons, reserve it for display use and rely on a fresh serviceable set for actual driving.

International Pickup 100 is associated here with three period-style sizes for 1974: G78-15, H70-15, and H78-15. The available replacement products include Coker Classic Bias Ply, Super Traxion, and Traxion series, with wide whitewall and blackwall sidewall treatments. Since more than one size appears within the same model year, the exact original fitment depends on the individual truck's configuration.

For restoration work, that means originality should be checked against factory literature, surviving equipment labels, old photographs, and marque-club knowledge rather than assumed from model year alone. Once the correct size is identified, the sidewall style becomes part of the authenticity decision as well. An International Pickup 100 restored as a work-focused truck may call for a different visual approach than one finished as a more upscale period pickup.

Correct tire fitment can absolutely affect the presentation, authenticity, and sometimes the judged quality of an International Pickup 100. Size, sidewall treatment, and overall tire character all influence whether the truck looks properly sorted for its era. A truck wearing a size or style that does not suit its original configuration can look visibly off even when the tire physically fits the wheel.

For owners concerned with show results or long-term collector value, tire choice should be treated as part of the restoration plan rather than a last-minute detail. Matching the right size first, then choosing the appropriate whitewall or blackwall style, usually brings the truck closer to a coherent period appearance. Marque clubs and judging standards are the best references when an International Pickup 100 is being prepared for serious evaluation.

International Pickup 100 tires are available here in wide whitewall and blackwall form, and either can be appropriate depending on how the truck was equipped and how it is being restored. Wide whitewalls are offered in the Coker Classic Bias Ply line, while blackwalls appear in the STA truck-style selections. The correct visual choice is tied less to the model name alone than to the truck's original presentation and intended restoration theme.

A more dressed, presentation-oriented International Pickup 100 can look right on wide whitewalls, especially if the rest of the truck is restored to a polished, period-correct standard. A blackwall often suits a utility-focused pickup or a restoration that emphasizes work-truck authenticity. If originality is the goal, compare sidewall style against period photos and equipment details from the specific truck rather than choosing on appearance alone.

Fresh, correctly fitted bias-ply tires can be suitable for public-road use on an International Pickup 100 when the truck itself is mechanically sound and the tires are in proper condition. The available choices here are all vintage-style bias-ply designs, so they should be treated as period-appropriate service tires rather than modern performance tires. Safe road use depends on correct size selection, proper inflation, sound wheels, and careful inspection.

In practical terms, an International Pickup 100 should be driven with an understanding of how bias-ply tires behave. Steering feel, tracking, braking response, and ride character will differ from modern radial-equipped vehicles, especially on grooved pavement or uneven roads. A cautious test drive after installation is a smart way to reacquaint yourself with the truck before using it in normal traffic.

Before driving an International Pickup 100, check tire inflation, visible sidewall condition, tread condition, valve stems, wheel security, and any sign of tube or rim-related air loss. Also confirm that the truck is wearing a matched set of the correct size rather than a mix of different alphanumeric sizes. On an older pickup, basic brake, steering, and suspension condition matter just as much as the tires.

That pre-drive routine is especially worthwhile if the International Pickup 100 has been parked for extended periods. A truck can look ready to go while still carrying aged tires, loose hardware, or weather-related deterioration elsewhere in the chassis. A few minutes of inspection before each outing reduces the chance of discovering a problem once the truck is already on the road.

An International Pickup 100 on vintage-style bias-ply tires should be driven at moderate, sensible speeds that suit the truck's age, mechanical condition, and period tire construction. These tires are meant to preserve the driving character of a 1970s collector pickup, not to duplicate the high-speed manners of a modern light truck tire. The appropriate pace is one that keeps the truck stable, comfortable, and well within the capability of the entire vehicle.

For most owners, that means treating an International Pickup 100 as a collector vehicle and building speed gradually while paying attention to steering response, braking feel, and road surface behavior. Heat, heavy loads, and long highway stretches all place more demand on an older truck-tire combination. Conservative road habits are part of using period-style tires responsibly and preserving the truck for the long term.
