1981 Ford Trucks F-350 Ranger Tires

The 1981 Ford Trucks F-350 Ranger uses four primary bias-ply tire sizes: 750-16, 800-16.5, 875-16.5, and 950-16.5. The correct one depends on the exact truck configuration, because this model range includes dual rear wheel applications, GVWR variations, and specialty setups such as heavy-duty front-end and snow-plow-prep versions.

Choosing correctly starts with identifying the exact sub-model and then confirming the wheel diameter on the truck. A 16-inch wheel and a 16.5-inch wheel are not the same, and the tire choice should also reflect whether the truck is a DRW setup or a single listed 950-16.5 application such as the Base or heavy-duty front-end version.

A 1981 Ford Trucks F-350 Ranger can use either a 16-inch or 16.5-inch rim, depending on the tire size and sub-model. The 750-16 size belongs to a 16-inch rim, while 800-16.5, 875-16.5, and 950-16.5 are all built for 16.5-inch rims.

That difference matters immediately because a tire for a 16-inch wheel cannot be used on a 16.5-inch wheel, and the reverse is also true. Before comparing brands or tread styles, check the wheel stamping or measure carefully so the tire size and rim diameter stay matched to the truck's actual setup.

Multiple tire sizes appear on the 1981 Ford Trucks F-350 Ranger because the model range covers more than one working configuration. Dual rear wheel trucks, GVWR-specific versions, and special equipment setups such as heavy-duty front-end or snow-plow-prep applications do not all use the same tire size or the same wheel diameter.

That means the truck's badge alone is not enough to select tires accurately. The safest approach is to confirm the exact sub-model, note whether the fitment is front, rear, or full vehicle where applicable, and verify the existing wheel diameter before narrowing the choice to a specific bias-ply tire size.

Start with the correct primary size for the exact 1981 Ford Trucks F-350 Ranger configuration, then confirm the matching wheel diameter. This truck range uses only bias-ply fitments, and the available sizes span both 16-inch and 16.5-inch rims, so size and wheel match come before any other decision.

After that, compare the tire's intended character. Some options lean toward traditional classic bias-ply presentation, while others are clearly truck-oriented designs such as Traxion, Super Transport, Transport Highway, or military-style NDT. Rim-width specifications, load figures where shown, and the truck's actual use all help narrow the choice.

Most 1981 Ford Trucks F-350 Ranger tire choices are blackwalls, especially in the 16.5-inch truck sizes and the more work-oriented 750-16 offerings. In 750-16, wide whitewall options are also available, creating a more traditional appearance than the blackwall truck tires used in the heavier-duty part of the lineup.

The sidewall decision should follow the truck's purpose. A blackwall usually suits a work-truck or utility presentation, while a wide whitewall can push a 16-inch setup toward a more vintage restored look. That appearance choice still has to stay within the correct size and wheel diameter for the particular truck configuration.

Tires for the 1981 Ford Trucks F-350 Ranger are available from Firestone, Lester, BFGoodrich, and STA, depending on size. The broadest brand variety appears in 750-16, while the 16.5-inch truck sizes center mainly on STA offerings in blackwall, truck-oriented bias-ply series.

Brand choice should be considered alongside the exact tire size, sidewall style, and intended use. A 750-16 buyer can compare more traditional classic bias-ply and whitewall options, while buyers in 800-16.5, 875-16.5, or 950-16.5 are really choosing among specialized truck-series constructions within the correct fitment.

A period-style 1981 Ford Trucks F-350 Ranger should begin with the correct primary bias-ply tire size for the exact truck configuration. From there, the visual direction depends on the wheel setup and how the truck is being presented, since 750-16 includes more traditional classic bias-ply choices while the 16.5-inch sizes stay firmly truck-oriented.

A restored work-truck look usually points toward blackwall truck series, especially on the 16.5-inch applications. On a 16-inch setup using 750-16, wide whitewall choices create a different vintage presentation. When exact originality matters, compare the tire decision with vehicle-specific historical references rather than relying on size alone.

Correct tire fitment matters a great deal on a 1981 Ford Trucks F-350 Ranger restoration because the truck uses several bias-ply sizes and two different wheel diameters. A tire that looks generally similar can still be wrong for the vehicle if it does not match the truck's configuration, wheel size, or intended heavy-duty equipment setup.

Fitment accuracy also shapes the truck's stance and overall visual character. A DRW truck, a heavy-duty front-end truck, and a snow-plow-prep truck should not be treated as the same application automatically. Confirming the exact sub-model and wheel size first keeps the restoration grounded in the truck's actual specification.

Modifications can absolutely affect tire fitment on a 1981 Ford Trucks F-350 Ranger. Aftermarket wheels, wheel swaps between 16-inch and 16.5-inch setups, suspension changes, altered ride height, or changes to dual rear wheel hardware can all change which tire size can be used safely and correctly.

A truck that no longer carries its original wheel setup should be checked as it sits today, not only by model name. Wheel diameter, wheel width, and available clearance at the fenders, suspension, and steering points all need attention before installing a bias-ply replacement in any of the listed sizes.

Before driving a 1981 Ford Trucks F-350 Ranger on new tires, inspect the wheels for the correct diameter and condition, make sure the tires are mounted in the proper size for the truck's configuration, and confirm even clearance around steering and suspension components. Lug hardware and wheel condition deserve close attention on a working one-ton pickup.

The tires themselves should also be checked for proper inflation, secure seating on the rim, and any early signs of rubbing once the truck is on the ground. A short, careful road test helps reveal vibration, pull, or clearance issues before the truck is asked to haul, tow, or cover longer distances.

Tires on a collector 1981 Ford Trucks F-350 Ranger should be inspected regularly for air loss, tread wear, sidewall cracking, bulges, and cuts, even if the truck is driven only occasionally. Bias-ply truck tires can spend long periods parked, so age and storage condition matter just as much as mileage.

Proper inflation and a clean, dry storage environment go a long way toward preserving the tires between outings. Keep the truck away from prolonged sunlight, excessive heat, and ozone sources when possible, and look over the tires before every drive rather than assuming low annual use means they are ready for the road.
