The 1975 Ford F-250 came from an era when Ford pickups were expected to do real work, whether that meant hauling, towing, four-wheel-drive use, or carrying camper equipment. That matters for tire selection, because this truck uses several heavy-duty bias-ply fitments rather than one universal size. Depending on the exact F-250 configuration, the primary sizes are 800-16.5, 875-16.5, 950-16.5, or 750-16, and wheel diameter is not the same across every sub-model. Available choices lean toward blackwall truck-oriented tread designs, with different STA series and additional 750-16 options from brands such as Firestone, BFGoodrich, and Lester. The key is matching the truck's exact sub-model and wheel setup before choosing for restoration, utility, or regular road use.
Which Tire Size Is Right for The 1975 Ford F-250
The 1975 Ford F-250 uses four primary tire sizes, and the correct one depends on the truck's exact sub-model and wheel diameter. Most applications center on 16.5-inch bias-ply truck tires, but one 4x4 configuration also uses a 750-16 bias-ply size on a 16-inch rim. Before choosing a tire, confirm both the sub-model and the actual wheel diameter on the truck, especially if it has seen years of service, replacement wheels, or suspension changes.
In the 800-16.5 size, the 800 refers to a nominal 8.00-inch section-width class, while 16.5 identifies the wheel diameter in inches. This is a bias-ply truck tire size that suits the period working character of a 1975 Ford F-250 and is used on several 16.5-inch wheel applications. Available choices include STA Super Transport and STA Traxion, both in blackwall form and truck-focused series. This size is worth considering when your specific F-250 configuration uses 16.5-inch wheels and you want to stay with a traditional heavy-duty bias-ply presentation.
The 875-16.5 designation uses a nominal 8.75-inch section-width class with a 16.5-inch wheel diameter. It is a bias-ply truck fitment for the 1975 Ford F-250 and appears across multiple sub-models, making it one of the core 16.5-inch sizes for this truck. Product choices include STA Traxion and STA Transport Highway, both offered as blackwall truck tires with a traditional work-oriented look. This size should be evaluated against the truck's exact GVWR-related configuration and wheel setup before selecting a tread style or tire series.
A 950-16.5 tire uses a nominal 9.50-inch section-width class and fits a 16.5-inch rim. For a 1975 Ford F-250, this is a larger bias-ply truck fitment used on several heavier-duty applications and offered in blackwall form through STA Traxion and STA Super Transport. Both available choices are truck-oriented bias-ply designs, and this size also carries stated load figures of 2780 at 60 psi on the applicable products. It makes sense to study this size closely when the truck uses the broader 16.5-inch fitment range and load-carrying demands are part of the decision.
The 750-16 size represents a nominal 7.50-inch section-width class for a 16-inch wheel. On the 1975 Ford F-250, this bias-ply size is tied to a specific 4x4 application and stands apart from the 16.5-inch fitments used elsewhere in the lineup. It has the broadest product variety, including blackwall, wide whitewall, military-style NDT, and several truck-oriented series from Firestone, BFGoodrich, Lester, and STA. This is the size to review carefully when your truck has 16-inch wheels and you want to balance utility use, vintage appearance, or restoration-minded styling.
Tire fitment for the 1975 Ford F-250 varies by drivetrain and GVWR grouping, so identifying the exact sub-model matters before choosing a size. Most covered configurations use 16.5-inch bias-ply sizes, while one 4x4 application also introduces a 16-inch option, making wheel confirmation especially important.

1975 Ford F-250 4x2 & Camper Special (GVWR 6900)
This Camper Special configuration uses 16.5-inch bias-ply tire sizes, with 800-16.5, 875-16.5, and 950-16.5 all associated with the sub-model. Selection comes down to confirming the truck's actual wheel setup and then choosing among the available blackwall truck-oriented series in the correct size.
1975 Ford F-250 4x2 & Camper Special (GVWR 7500 & 8100)
This higher-GVWR Camper Special grouping centers on 16.5-inch bias-ply fitment, using 875-16.5 and 950-16.5 rather than the smaller 800-16.5 option. That makes it especially important to verify the truck's exact GVWR-related configuration before comparing tread style, load-oriented product details, and wheel compatibility.
The 4x2 GVWR 6200 version uses 16.5-inch bias-ply sizes, with 800-16.5, 875-16.5, and 950-16.5 all in the fitment range. Tire choice starts with confirming which wheel diameter is actually on the truck, then narrowing the selection to the correct size and preferred truck-style series.
This 4x4 grouping uses 16.5-inch bias-ply fitments, including 800-16.5, 875-16.5, and 950-16.5. Choosing among them means matching the tire to the truck's present wheel setup and intended use, especially on vehicles that may have seen wheel, axle, or suspension changes over time.
For this 4x4 GVWR range, the applicable sizes remain 800-16.5, 875-16.5, and 950-16.5, all in bias-ply construction. The practical decision is less about sidewall appearance and more about confirming the correct size on the truck's existing 16.5-inch wheels and selecting the tread series that fits its role.
This is the most important sub-model to verify closely because it spans both 16.5-inch bias-ply sizes and a 750-16 bias-ply fitment on a 16-inch wheel. Tire selection here starts with wheel-diameter confirmation, since that determines whether truck-oriented 16.5-inch options or the broader 750-16 assortment applies.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1975 Ford F-250 Tires for Sale
Available 1975 Ford F-250 tires focus on bias-ply truck fitments, with STA covering the 16.5-inch sizes and the 750-16 size adding Firestone, BFGoodrich, and Lester choices. Buyers can compare blackwall truck series such as Traxion, Super Transport, Transport Highway, and Super Traxion, plus selected wide whitewall and military-style 750-16 options.
Common 1975 Ford F-250 tire questions usually center on identifying the right size by sub-model, confirming whether the truck uses 16-inch or 16.5-inch wheels, and choosing between the available bias-ply truck tires for use, appearance, and roadworthiness.
Tire Size & Fitment
What tire size fits a 1975 Ford F-250?
A 1975 Ford F-250 can use 800-16.5, 875-16.5, 950-16.5, or 750-16, depending on the exact sub-model. All of these are bias-ply primary fitments. Most covered configurations use 16.5-inch tires, while one 4x4 GVWR 7700 application also includes a 750-16 size on a 16-inch wheel.
The practical step is confirming the truck's exact drivetrain and GVWR grouping, then checking the wheel diameter currently on the vehicle. A 16-inch and a 16.5-inch wheel are not the same, and years of use can bring wheel swaps or other changes. Once that is verified, the right size can be narrowed down much more confidently.
What size rim does a 1975 Ford F-250 use?
The 1975 Ford F-250 uses either a 16.5-inch or 16-inch rim, depending on the sub-model and tire size. The 800-16.5, 875-16.5, and 950-16.5 sizes are for 16.5-inch wheels, while the 750-16 size uses a 16-inch wheel. That split is one of the most important fitment details on this truck.
Wheel diameter should be checked before any tire selection, especially on an older pickup that may have had replacement wheels installed over the years. Rim width matters too, but the first checkpoint is always the bead-seat diameter. A tire meant for a 16-inch rim cannot be treated as the same thing as one intended for a 16.5-inch rim.
Why does the 1975 Ford F-250 have more than one tire size?
The 1975 Ford F-250 spans several sub-models, including 4x2, 4x4, and Camper Special configurations with different GVWR groupings. That creates multiple primary tire sizes within the same model year. Some versions share the 16.5-inch sizes 800-16.5, 875-16.5, and 950-16.5, while a specific 4x4 GVWR 7700 application also includes 750-16.
That means the correct tire is tied to the exact version of the truck rather than the F-250 name alone. Buyers should verify the truck's sub-model and inspect the wheels actually installed before comparing products. This is especially important on working trucks, because service replacements and later modifications can change what is currently on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 1975 Ford F-250 tire?
Start with the exact tire size and wheel diameter used by the truck's sub-model, since the 1975 Ford F-250 does not use one universal fitment. All primary sizes are bias-ply, so the next decision is whether the truck needs a work-oriented tread, a more restoration-minded appearance, or a specific load-capable product within the correct size.
After size is confirmed, compare the available series, sidewall style, rim-width compatibility where stated, and any published load figures that apply to the product you are considering. A farm truck, a restored pickup, and a camper-duty truck may point toward different choices even within the same size. Existing wheel condition and actual vehicle use should guide the final decision.
What sidewall styles are available for 1975 Ford F-250 tires?
Most 1975 Ford F-250 tire options are blackwall truck tires, especially in the 16.5-inch sizes and the utility-focused 750-16 offerings. The 750-16 size also adds wide whitewall choices from Lester, BFGoodrich, and Firestone, creating a more appearance-driven alternative to the standard blackwall truck presentation.
Sidewall style affects the truck's look more than its basic fitment, so the right choice depends on how the vehicle is being presented. A blackwall usually suits a work-truck or utility-oriented appearance, while a wide whitewall can push the truck toward a more vintage custom or restoration-style look. Keeping the correct size and wheel diameter still comes first.
What brands offer tires for the 1975 Ford F-250?
Tires for the 1975 Ford F-250 are available from STA, Firestone, BFGoodrich, and Lester. STA covers the 16.5-inch truck sizes and also appears in 750-16, while Firestone, BFGoodrich, and Lester expand the 750-16 selection with both truck-oriented and appearance-focused bias-ply options.
Brand choice should be considered alongside size, series, sidewall style, and the truck's intended use rather than by name alone. Some offerings lean heavily toward military-and-truck applications, while others bring wide whitewall styling into the mix. Once the correct size is confirmed, the product grid becomes a comparison of presentation, published specifications, and wheel compatibility.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Ford F-250?
A period-style 1975 Ford F-250 tire choice starts with the truck's correct bias-ply size and wheel diameter, then narrows by tread character and sidewall appearance. Most applications point toward blackwall truck tires in 16.5-inch sizes, while 750-16 opens the door to both truck-use patterns and more appearance-oriented bias-ply selections.
For a work-truck look, blackwall truck series usually make the most visual sense. A 750-16 wide whitewall creates a very different presentation and should be chosen only if that style matches the truck's intended finished look. When exact originality matters, vehicle-specific photos, marque references, and restoration documentation are the best guides beyond size and construction.
How does tire construction affect the appearance of a restored 1975 Ford F-250?
On a restored 1975 Ford F-250, bias-ply construction helps preserve the truck's period-style visual character because the primary fitments for this model are bias-ply sizes. That traditional construction aligns with the truck's mid-1970s working-truck context and with the blackwall, utility-focused tire choices that dominate the available selection.
Appearance is shaped by more than tread alone. Sidewall profile, overall stance, and whether the truck wears blackwalls or wide whitewalls all influence how authentic or stylized the finished vehicle looks. Even on a restoration-focused truck, the tire still has to match the correct wheel diameter and intended use, so visual goals should be balanced with fitment discipline.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Ford F-250?
Yes, modifications can affect tire fitment on a 1975 Ford F-250. Aftermarket wheels, suspension lifts, altered springs, axle changes, or body modifications can all change the space available around the tire and may also change the wheel diameter or width from the truck's original-style setup.
That matters even more here because the F-250 uses both 16-inch and 16.5-inch wheel applications depending on sub-model. Any truck that has been modified should have its actual wheel diameter, wheel width, and clearance checked at the front and rear before a new tire is chosen. Steering sweep and loaded suspension clearance are both worth confirming on a working pickup.
What should I inspect before driving a 1975 Ford F-250 on new tires?
Before driving a 1975 Ford F-250 on new tires, inspect the wheels for damage or corrosion, confirm that the tire size matches the wheel diameter, and make sure the tires are inflated to an appropriate pressure for the product and intended use. Lug hardware, valve stems, and overall mounting condition also deserve close attention.
An older truck should also be checked for clearance at full steering lock and under suspension movement, especially if it has seen wheel or suspension changes. After the first miles, recheck pressure and look for any signs of rubbing, uneven seating, or unusual wear. That follow-up inspection helps catch fitment issues before the truck goes into regular service.
How should tires on a collector 1975 Ford F-250 be maintained?
Tires on a collector 1975 Ford F-250 should be kept clean, properly inflated, and inspected regularly for cracking, cuts, bulges, flat spotting, and air loss. Because many collector trucks are driven infrequently, condition matters just as much as tread depth. A bias-ply truck tire can age visibly even when the vehicle sees limited road time.
Storage habits have a big effect on long-term condition. Parking the truck away from prolonged sunlight, moisture, and ozone sources helps preserve the sidewalls, and moving the vehicle occasionally can reduce spotting from long static periods. Before any longer drive, check pressure, inspect the tread and casing carefully, and make sure the spare matches the wheel and tire setup in use.
