1981 Ford Trucks F-250 Ranger XLT Tires

The 1981 Ford Trucks F-250 Ranger XLT uses four primary tire sizes: 800-16.5, 875-16.5, 8.75R16.5, and 950-16.5. The correct size depends on the truck's exact sub-model, including drive layout, cab configuration, and GVWR, so there is not one universal tire size for every version of this F-250 Ranger XLT.

The practical first step is identifying the truck exactly as equipped, then confirming the wheel size already on the vehicle. Many versions share the same 16.5-inch rim diameter but use different width classes or construction types, so choosing by model name alone can lead to the wrong tire being considered.

The listed tire fitments for the 1981 Ford Trucks F-250 Ranger XLT all use a 16.5-inch rim diameter. That applies across the size range, including 800-16.5, 875-16.5, 8.75R16.5, and 950-16.5, even though the exact tire width and construction can change from one sub-model to another.

Rim diameter is only the starting point, because the wheel still needs to suit the tire's width and intended load-carrying role. On an older truck, it is smart to confirm the actual wheels on the vehicle before ordering tires, especially if the truck may have been changed from its original service setup over time.

This truck line covers multiple 4x2, 4x4, Super Cab, long-bed, and GVWR combinations, so tire fitment changes within the 1981 Ford Trucks F-250 Ranger XLT range. Some versions use narrower bias-ply sizes, some use wider bias-ply sizes, and some include 8.75R16.5 as a radial primary fitment.

That variation means the buyer should match tires to the exact truck rather than treating the entire model line as a single fitment group. Weight rating and configuration can matter just as much as body style, and the safest approach is to verify the truck's sub-model details along with the wheels currently installed.

8.75R16.5 is a radial tire size for the 1981 Ford Trucks F-250 Ranger XLT. The R in the size designation identifies radial construction, and it appears as a primary fitment on certain sub-models rather than as a general replacement for every F-250 Ranger XLT configuration.

That distinction matters because some other versions of this truck use bias-ply sizes such as 800-16.5, 875-16.5, or 950-16.5 instead. A truck equipped for 8.75R16.5 should be checked carefully for wheel suitability and overall setup before switching construction types or moving to a different primary size family.

The answer depends on the exact sub-model and the tire size it uses. Many 1981 Ford Trucks F-250 Ranger XLT configurations use bias-ply primary fitments, while certain versions use 8.75R16.5 as a radial primary fitment, so construction choice is tied closely to the truck's original size path and wheel setup.

A buyer focused on traditional truck appearance may want to stay with the bias-ply fitment already associated with that configuration. A truck that uses the radial size should be treated differently, and any change in construction should be approached by checking wheel compatibility, clearance, and the vehicle's intended working or road-going use.

Start by confirming that the exact sub-model has a radial primary fitment, because this truck line includes both bias-ply and radial applications. Then verify the actual wheel diameter and width on the truck, since every listed size uses a 16.5-inch rim but the tire widths and construction types are not the same across all configurations.

A construction change should also be checked against steering clearance, fender clearance, suspension condition, and the truck's load-carrying role. On an older F-250, it is especially important to inspect whether aftermarket wheels, ride-height changes, or service-related modifications have altered the setup from the way the truck originally left the line.

Begin with the exact primary size for the truck, since the 1981 Ford Trucks F-250 Ranger XLT can use 800-16.5, 875-16.5, 8.75R16.5, or 950-16.5 depending on configuration. After size, the next priorities are construction type, wheel compatibility, and whether the truck is being kept close to a period-style working appearance or prepared for regular road use.

Once the correct fitment path is clear, compare the product differences that actually matter for this truck category, such as tire series, rim-width details where stated, and load information where it appears. A heavier GVWR truck should not be treated the same way as a lighter version, even within the same Ranger XLT model family.

The available products for the 1981 Ford Trucks F-250 Ranger XLT come from STA. Across the listed sizes, STA supplies truck-oriented options in series such as Super Transport, Traxion, and Transport Highway, all presented in blackwall form for the applicable bias-ply fitments covered here.

Because the product range stays within one brand, the real comparison is less about switching manufacturers and more about selecting the right size and series for the truck's setup. It also helps to compare any stated rim-width or load figures where they are given, especially on wider heavy-duty sizes such as 950-16.5.

The tire series available for the 1981 Ford Trucks F-250 Ranger XLT include STA Super Transport, STA Traxion, and STA Transport Highway. Series availability depends on the exact size, so not every series appears in every fitment, and the product mix changes between 800-16.5, 875-16.5, and 950-16.5.

That means the best way to use the series information is after confirming the truck's correct tire size. Once the fitment is narrowed down, the series names help distinguish the available truck-tire choices within that size rather than encouraging a buyer to start with appearance or tread style before fitment basics are settled.

A period-style choice starts with the exact primary tire size used by the truck's sub-model, then stays within the corresponding bias-ply or radial construction family. On this F-250 Ranger XLT, that can mean a traditional numeric bias-ply truck tire such as 800-16.5, 875-16.5, or 950-16.5, or 8.75R16.5 on the versions that use a radial fitment.

Appearance should follow fitment, not override it. Blackwall truck tires are the available style here, and the final choice usually comes down to selecting the proper series within the correct size. When exact restoration accuracy matters, the truck's original literature or marque-specific references are worth checking before committing to a final presentation.

Tire construction can change the restored truck's visual character even when the rim diameter stays the same. On the 1981 Ford Trucks F-250 Ranger XLT, bias-ply and radial fitments both appear in the range, so the sidewall shape and overall presentation can differ depending on which construction matches the truck's configuration.

For a restoration-oriented owner, that means the right construction is part of the truck's finished look as well as its fitment. A bias-ply tire supports a more traditional heavy-duty truck presentation, while a radial-equipped version should reflect the fitment path used on that sub-model instead of being treated as a cosmetic decision alone.

Yes, modifications can change how a tire fits on a 1981 Ford Trucks F-250 Ranger XLT even when the tire size itself is correct for a listed sub-model. Aftermarket wheels, changes in wheel width, suspension alterations, ride-height changes, or body modifications can all affect clearance and the way a 16.5-inch truck tire sits on the vehicle.

That is why an older F-250 should be checked as it exists today, not only by original model description. The more variation there is in wheel or suspension setup, the more important it becomes to confirm steering clearance, fender space, and wheel suitability before settling on one of the truck's primary tire sizes.

Before putting a 1981 Ford Trucks F-250 Ranger XLT back into regular use, inspect wheel condition, valve stems, lug hardware, and overall tire seating on the rim. It is also smart to check for suspension wear, steering looseness, brake issues, and any signs that the truck has uneven stance or clearance problems that could affect the new tires.

A road test should begin with proper inflation for the tire being used and a close look at sidewall condition, tread behavior, and any sign of rubbing after the first miles. Older work trucks often have long service histories, so catching a wheel or chassis issue early is just as important as choosing the right tire size.

Collector-truck tires should be kept clean, properly inflated, and inspected regularly for cracking, cuts, bulges, and uneven wear. On a 1981 Ford Trucks F-250 Ranger XLT, that matters even more because 16.5-inch truck tires may spend long periods parked between uses, allowing age and storage conditions to become as important as tread depth.

Storage habits make a real difference on low-mileage trucks. Keeping the vehicle away from prolonged sun, moisture, and ozone-producing equipment helps preserve the tires, and occasional pressure checks are worthwhile even when the truck is not being driven often. Any sign of air loss or visible deterioration deserves attention before road use.
