1977 Ford F-250 Tires

A 1977 Ford F-250 does not use one universal tire size across the entire model line. Primary bias-ply fitments include 800-16.5, 875-16.5, 950-16.5, and 750-16, depending on the exact drivetrain, cab configuration, Camper Special application, and GVWR.

The practical first step is confirming the truck’s exact sub-model and the wheel diameter actually on the vehicle. Some F-250s stay within the 16.5-inch family, while others also use 16-inch wheels, so a replacement tire should be matched to both the truck’s configuration and its current wheel setup before comparing tread styles or load-oriented truck series.

The 1977 Ford F-250 uses either a 16-inch or 16.5-inch rim, depending on the tire size fitted to the truck. The 750-16 size uses a 16-inch rim, while 800-16.5, 875-16.5, and 950-16.5 all use 16.5-inch rims.

That difference matters because a 16-inch tire and a 16.5-inch tire are not the same fitment even when they appear close at a glance. Checking the wheel itself, the tire sidewall, and the truck’s exact sub-model helps avoid ordering a tire for the wrong rim diameter, especially on older pickups that may have had wheels changed during their working life.

The 1977 Ford F-250 spans multiple working configurations, so tire fitment changes with sub-model details such as 4x2 or 4x4 layout, Super Cab or Camper Special use, and GVWR. That is why the truck appears with four primary bias-ply sizes instead of one size shared across the full line.

For a buyer, that means the nameplate alone is not enough. The most accurate path is to identify the exact sub-model, then confirm whether the truck has 16-inch or 16.5-inch wheels and compare the mounted tire size. That approach is especially important on heavy-duty vintage pickups, where past wheel swaps or service replacements are common.

Start with the correct primary size for the truck’s exact configuration, then match that size to the proper wheel diameter. On a 1977 Ford F-250, that can mean choosing among 800-16.5, 875-16.5, 950-16.5, or 750-16, all in bias-ply construction.

After size and rim diameter are settled, look at how the truck will be used and what presentation fits the project. Some options lean toward truck and traction-oriented blackwall service, while 750-16 also brings in wide whitewall choices. Rim-width guidance, load figures where shown, and the truck’s intended hauling or collector use all deserve a closer look before deciding.

Tires for the 1977 Ford F-250 are available from STA, Firestone, BFGoodrich, and Lester across the applicable primary sizes. STA covers the 16.5-inch truck sizes and also appears in 750-16, while Firestone, BFGoodrich, and Lester appear within the 750-16 selection.

Brand is only one part of the decision on this truck. The more useful comparison is how each option lines up with the confirmed size, wheel diameter, sidewall style, and tire series that suit the vehicle’s purpose. A work-oriented blackwall truck tire and a wide whitewall bias-ply can both fit the same size while serving very different project goals.

Available series for the 1977 Ford F-250 include STA Traxion, STA Super Transport, STA Transport Highway, STA Super Traxion, Firestone Classic Bias Ply, Firestone Classic Military, Lester Classic Bias Ply, and Silvertown Classic Bias Ply. The exact series depends on the tire size being considered.

Those series help separate one product choice from another even within the same fitment. Some are clearly truck and military-oriented in character, while others in 750-16 offer a more restoration-minded visual presentation. Once the correct size is confirmed, the series name becomes a useful shorthand for comparing tread purpose, sidewall treatment, and overall style.

A period-style 1977 Ford F-250 usually starts with the correct primary bias-ply size for the truck’s exact sub-model and wheel diameter. For many configurations that means a 16.5-inch truck fitment such as 800-16.5, 875-16.5, or 950-16.5, while some trucks use 750-16 on a 16-inch wheel.

From there, the visual goal matters. Blackwall truck series preserve a utilitarian heavy-duty look, while 750-16 also opens up wide whitewall choices for a different restored presentation. Exact originality can vary by individual truck history, so owners pursuing a highly accurate restoration should compare the chosen size and appearance against vehicle-specific documentation and known wheel setup.

For this truck, the primary fitments are bias-ply, and that construction is part of the vehicle’s authentic period feel. A bias-ply tire on a 1977 Ford F-250 keeps the visual character in line with the truck’s original working era, especially when paired with the proper wheel diameter and a traditional blackwall truck pattern.

Appearance is shaped by more than construction alone, though. Sidewall treatment, tread style, and the difference between a 16-inch and 16.5-inch setup all influence how the finished truck looks. On 750-16, wide whitewall choices create a very different presentation from a blackwall military or transport-style tire, even though each remains within a bias-ply format.

Yes, modifications can affect tire fitment on a 1977 Ford F-250, especially because this truck already spans both 16-inch and 16.5-inch wheel diameters. Aftermarket wheels, suspension changes, altered ride height, or previous owner conversions can all change which tire size is appropriate for the truck now.

A careful check should include wheel diameter, wheel width, steering clearance, and space around the fenders and suspension at full turn and full compression. Older heavy-duty pickups often live long working lives, so the safest approach is to inspect what is on the vehicle today rather than assuming the truck still carries its original wheel and tire arrangement.

Before driving a 1977 Ford F-250 on new tires, inspect the wheels for damage, confirm that the rim diameter matches the chosen tire, and check for any interference around suspension, steering, and bodywork. It is also wise to verify inflation, lug hardware condition, and overall tire seating once the tires are mounted.

A truck of this age also deserves a broader once-over before regular road use. Look for cracked or weathered old tires being replaced, signs of uneven wear that may point to alignment or suspension issues, and any air loss after installation. A short initial drive followed by a recheck can help catch clearance or pressure issues early.

Tires on a collector 1977 Ford F-250 should be maintained with regular pressure checks, visual inspections, and attention to age even if the truck is driven only occasionally. Bias-ply truck tires on older pickups can spend long periods parked, so tread depth alone is not enough to judge their condition.

Storage conditions matter on a collector truck. Keeping the F-250 away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the sidewalls, while periodic inspection for cracking, bulges, cuts, or flat spotting helps catch problems before road use. Tires should also be checked before longer drives, especially after seasonal storage.
