1981 Ford Trucks F-250 Ranger Tires

The 1981 Ford Trucks F-250 Ranger uses four primary tire sizes: 800-16.5, 875-16.5, 950-16.5, and 8.75R16.5. The first three are bias-ply sizes, while 8.75R16.5 is a radial fitment used on certain sub-models rather than across the entire range.

The correct choice depends on the truck's exact configuration, especially 4x2 versus 4x4, cab style, and GVWR. Since all of these sizes use a 16.5-inch rim, the key step is confirming the specific sub-model and then checking that the wheels currently on the truck still match the intended tire size and construction.

The primary tire fitments for the 1981 Ford Trucks F-250 Ranger all use a 16.5-inch rim diameter. That applies whether the truck is equipped with 800-16.5, 875-16.5, 950-16.5, or the 8.75R16.5 radial size.

Rim diameter is only part of the fitment picture on this truck. Wheel width still matters, especially when comparing sizes such as 800-16.5 and 950-16.5, and older pickups are often changed over the years. Checking the wheel stamp, measuring the wheel, and confirming the truck's GVWR-specific fitment will help prevent choosing the right diameter but the wrong overall setup.

The 1981 Ford Trucks F-250 Ranger was offered in multiple configurations, including 4x2 and 4x4 versions, Super Cab variants, and several GVWR ratings. Because of that, tire fitment is not the same across the full model line, and some sub-models also include a radial option alongside bias-ply sizes.

That variation means the model name by itself is not enough to choose a tire. The truck's rating and body configuration need to be identified first, especially on vehicles that may have had wheel changes during their working life. Once the exact sub-model is confirmed, it becomes much easier to narrow the choice to the correct size and construction.

On the 1981 Ford Trucks F-250 Ranger, 8.75R16.5 is a radial tire size. It appears as a primary fitment on certain sub-models, while the other listed sizes for this truck family are bias-ply formats such as 800-16.5, 875-16.5, and 950-16.5.

That distinction matters because a radial primary fitment should not be treated the same way as a bias-ply size with a later conversion. Before choosing 8.75R16.5, verify that the truck's exact GVWR and configuration are among the ones that use it, and make sure the current 16.5-inch wheels are appropriate for the radial setup being considered.

That depends on the specific 1981 Ford Trucks F-250 Ranger sub-model and what you want from the truck. Several configurations use bias-ply sizes as their primary fitments, while some sub-models also use the 8.75R16.5 radial as a primary fitment rather than as an aftermarket substitute.

A bias-ply tire usually makes the most sense when maintaining a traditional vintage truck presentation, while a radial fitment may appeal to owners whose exact configuration already used one. The right decision starts with the truck's actual specification, then moves to wheel compatibility, intended driving use, and whether the truck is being preserved in a more period-style form.

Start by confirming whether the truck's exact sub-model already uses 8.75R16.5 as a primary radial fitment. If it does not, the change should be approached carefully rather than assumed, because the listed primary sizes on this F-250 Ranger include several bias-ply applications tied to different GVWR and body configurations.

Wheel diameter is only the first check, since all of these sizes share a 16.5-inch rim. Wheel width, tire clearance, suspension condition, and the truck's load needs should also be reviewed before changing construction. On an older pickup, it is also smart to confirm that the current wheels are the ones intended for the truck and not a later replacement.

A 950-16.5 tire for the 1981 Ford Trucks F-250 Ranger should first be chosen on fitment, because this size belongs to higher-capacity configurations and is not correct for every sub-model. Available products in this size are bias-ply blackwall STA truck tires in the Traxion and Super Transport series.

After confirming that 950-16.5 is the right size for the truck, compare the wheel setup and the intended use. Applicable products in this size include stated rim-width guidance and load-capacity figures, which are useful when the truck still sees real road duty. The tread series can then be selected with the truck's work-oriented or restoration-oriented goals in mind.

The available products for the 1981 Ford Trucks F-250 Ranger are from STA. Across the bias-ply sizes offered for this truck, STA appears in several series including Super Transport, Traxion, and Transport Highway.

Because the brand selection is concentrated, the buying decision is less about comparing manufacturers and more about comparing the correct size and tire series within the lineup. It is still important to match the truck's exact sub-model first, since not every size applies to every F-250 Ranger configuration, even though the wheel diameter remains 16.5 inches throughout.

For the 1981 Ford Trucks F-250 Ranger, the available tire series include STA Super Transport, STA Traxion, and STA Transport Highway. These appear across the bias-ply 16.5-inch truck sizes used on this model line, with blackwall styling throughout the currently available product range.

Series choice becomes useful after the correct tire size has been confirmed for the truck's GVWR and configuration. At that stage, the comparison can shift to tread character, stated rim-width guidance where available, and whether the truck is being outfitted for a traditional work-truck appearance or for more general road use within its original-style fitment range.

A period-style 1981 Ford Trucks F-250 Ranger usually starts with the correct 16.5-inch primary size for the truck's exact sub-model, then stays within the bias-ply or radial construction used for that configuration. Bias-ply sizes such as 800-16.5, 875-16.5, and 950-16.5 play a major role in preserving the truck's traditional stance and look.

The appearance decision should follow fitment, not replace it. Once the right size is confirmed, a blackwall truck tire in a suitable series can help maintain the visual character expected of an early-1980s working Ford pickup. When exact originality matters, it is wise to compare against truck-specific historical references before settling on a final construction or tread pattern.

Tire construction changes more than ride and handling on a restored 1981 Ford Trucks F-250 Ranger; it also affects the truck's visual character. The bias-ply sizes used on many sub-models give the truck a more traditional vintage work-truck presentation, while the 8.75R16.5 radial reflects a different fitment path used on certain configurations.

That makes construction part of the restoration decision, especially on a truck where wheel and tire stance are easy to notice. A buyer trying to preserve a period-style look will usually want to begin with the exact size and construction assigned to the specific sub-model, then choose among the available blackwall series without assuming that any one tire is universally correct.

Yes, modifications can affect tire fitment on a 1981 Ford Trucks F-250 Ranger even when the truck still uses a 16.5-inch wheel. Changes such as aftermarket wheels, different wheel widths, suspension alterations, or body modifications can alter the way 800-16.5, 875-16.5, 950-16.5, or 8.75R16.5 sit on the truck.

That is especially important on older pickups because many have been changed over decades of work and repair. Before choosing new tires, confirm the actual wheel dimensions, check steering and fender clearance, and compare the current setup to the truck's exact GVWR-specific fitment. A size that belongs on one F-250 Ranger configuration should not be assumed to suit another without checking.

Before driving a 1981 Ford Trucks F-250 Ranger on new tires, inspect the wheels for correct diameter and condition, confirm the lug hardware is appropriate, and make sure the tires are inflated correctly for the application. It also helps to check for obvious alignment or suspension issues that could affect tire wear from the start.

After installation, look over sidewall clearance, front-end turning clearance, and the space around the rear wheel openings under load. On a vintage truck, wheel substitutions and worn suspension parts are common enough that a final visual check is worth doing even when the size itself is correct. A short, careful test drive can reveal rubbing, pull, or other setup problems early.

Tires on a collector 1981 Ford Trucks F-250 Ranger should be checked regularly for pressure, tread condition, sidewall cracking, bulges, cuts, and slow air loss. That matters even on trucks that are driven sparingly, because age and storage conditions can affect tires long before the tread looks worn out.

Good storage habits help preserve vintage truck tires between drives. Keeping the truck away from prolonged sunlight, heat, moisture, and ozone sources can reduce unnecessary aging, and occasional movement helps avoid long-term flat spotting. It is also smart to inspect the spare and any older wheel assemblies at the same time, since trucks often carry components that have been overlooked for years.
