1975 Ford F-350 Tires

A 1975 Ford F-350 can use 750-16, 800-16.5, 875-16.5, 950-16.5, or 12-16.5 tires, all in bias-ply construction. The correct size depends on the truck’s exact configuration, including GVWR, wheelbase, and whether it is a dual-rear-wheel or camper-oriented application.

That means there is not one universal tire size for every 1975 F-350. The first thing to verify is the actual wheel diameter, since both 16-inch and 16.5-inch wheels were used. After that, match the truck’s exact sub-model and, where applicable, front or rear fitment before comparing brands, tread series, or sidewall appearance.

The 1975 Ford F-350 uses either a 16-inch or a 16.5-inch rim, depending on the tire size and truck configuration. The 750-16 fits a 16-inch wheel, while 800-16.5, 875-16.5, 950-16.5, and 12-16.5 fit 16.5-inch wheels.

That difference matters because 16-inch and 16.5-inch tires are not the same thing, even when the numbers look close at a glance. Before ordering replacement tires, check the wheel itself and confirm the current size on the truck. On older work trucks, wheel swaps over the years are common enough that a visual assumption can lead to the wrong tire.

Ford offered the 1975 F-350 in several heavy-duty configurations, so tire size changes with GVWR, wheelbase, and specialty uses such as Camper Special, Super Camper Special, and dual-rear-wheel setups. Some versions also separate front and rear fitment, especially on the more specialized truck applications.

That is why two trucks with the same year and model badge may not use the same tire. A basic wheel check is important, but it is only part of the job. The truck’s exact configuration should be matched first, then the replacement tire can be narrowed by size, tread style, and whether the goal is working utility or a more restoration-minded presentation.

Start with the fact that 750-16 is a 16-inch bias-ply fitment used on certain 1975 Ford F-350 configurations. Within that size, choices vary by brand, sidewall style, tire series, load capacity on some products, and whether the tire is aimed more at traditional passenger-style appearance or truck-duty service.

A truck that is restored for shows may call for a different presentation than one that still sees hauling or farm use. Wide whitewall and blackwall options exist in 750-16, along with highway, traction, and military-style patterns. Checking the wheel width, expected load use, and the truck’s actual sub-model will help narrow the right type of 750-16 tire.

Sidewall choice depends heavily on size. In 750-16, the available styles include blackwall and wide whitewall, while the larger 16.5-inch truck sizes shown for the 1975 Ford F-350 are offered as blackwall tires. That creates a noticeable difference in appearance between the 16-inch and 16.5-inch fitments.

For a more traditional working-truck look, blackwall is the natural direction across all sizes. A buyer seeking a more restoration-oriented or period-style presentation will find the most visual variety in 750-16. The important step is not choosing sidewall appearance first, but making sure the truck’s correct wheel diameter and tire size are confirmed before appearance becomes the deciding factor.

Brand availability varies by size on the 1975 Ford F-350. The 750-16 size includes Firestone, Lester, BFGoodrich, and STA options, while the 800-16.5, 875-16.5, 950-16.5, and 12-16.5 sizes are represented by STA truck tires in the available product range.

That means brand comparison is widest if the truck uses 750-16, especially for buyers balancing truck use with visual style. On the 16.5-inch sizes, the decision is less about brand variety and more about choosing the appropriate STA series for the truck’s duty. Once the correct size is confirmed, compare tread type, sidewall appearance, and any load or rim-width details that apply.

A period-style 1975 Ford F-350 should begin with the truck’s correct bias-ply size, since the overall look depends as much on size and wheel diameter as on brand or tread pattern. For 750-16 applications, there is more visual variety, including blackwall and wide whitewall choices, while the 16.5-inch truck sizes lean toward more commercial blackwall presentations.

The right answer depends on what kind of truck is being restored. A work-oriented F-350 may look most at home with a blackwall truck tire, while a more presentation-focused build may benefit from one of the 750-16 whitewall options if that size belongs on the truck. For exact originality, vehicle-specific historical references should guide the final appearance choice.

Correct tire fitment matters a great deal on a 1975 Ford F-350 because these trucks used multiple heavy-duty sizes and two different wheel diameters. The visual stance, working character, and overall authenticity of the truck can change noticeably if the tire size, wheel diameter, or front-to-rear setup is not matched to the truck’s actual configuration.

That is especially important on Camper Special, Super Camper Special, and dual-rear-wheel trucks, where the tire choice is part of the vehicle’s original purpose. Even if the goal is not concours-level originality, staying with the proper size family helps preserve the truck’s proportions. Confirm the exact sub-model and wheel setup first, then choose tread style and sidewall appearance second.

Yes. Wheel swaps, changes between 16-inch and 16.5-inch wheels, suspension alterations, or body and axle changes can all affect tire fitment on a 1975 Ford F-350. That matters even more on a truck with multiple original tire sizes, front and rear application differences, and both single- and dual-rear-wheel configurations.

A modified truck should be checked for wheel diameter, wheel width, and clearance at full steering and suspension movement before replacement tires are chosen. Older F-350s often have had working lives that included parts changes, so the tire that belongs on paper may not match what is physically on the truck now. Verifying the actual setup prevents expensive fitment mistakes.

Before road use, inspect the wheels for correct diameter and condition, make sure the tires match the truck’s intended front or rear application, and confirm that inflation is appropriate for the tire and load use. It is also smart to check for rubbing, uneven suspension height, loose steering components, and any signs that the truck has mismatched wheel hardware.

A 1975 F-350 is a heavy-duty truck, so tire condition alone is not the full story. Look over the brakes, bearings, shocks, springs, and alignment, especially if the truck has been stored or used intermittently. A short, careful test drive followed by another look for clearance issues, heat buildup, or air loss is a sensible final check before regular road use.

Tires on a collector 1975 Ford F-350 should be checked regularly for air loss, sidewall cracking, bulges, cuts, tread wear, and signs of age-related hardening. Because many surviving F-350s are driven less often than they were when new, long periods of storage can be as important as mileage in determining tire condition.

Keep the truck stored away from prolonged sunlight, excess moisture, and ozone sources such as electric motors when possible, and maintain proper inflation during storage and use. It also helps to inspect the tires before each drive rather than waiting for a yearly check. On an older heavy-duty truck, catching condition issues early is part of protecting both drivability and appearance.
