1973 Jeep Truck Truck Tires

The 1973 Jeep Truck Truck uses four primary bias-ply tire sizes: 700-16, F78-15, H78-15, and 750-16. The correct size depends on the exact sub-model, because some versions use only 16-inch tires while others may use either 15-inch or 16-inch fitments.

The practical first step is matching the truck's sub-model to the wheel diameter actually on the vehicle. Many older Jeep trucks have seen wheel changes over the years, so the sidewall size on the current tire and the diameter stamped on the wheel should both be checked before selecting a replacement.

A 1973 Jeep Truck Truck uses either a 15-inch or 16-inch rim, depending on the sub-model and tire size. F78-15 and H78-15 are 15-inch fitments, while 700-16 and 750-16 are built for 16-inch wheels.

That makes rim confirmation one of the most important steps before ordering tires. The tire size itself tells the rim diameter, but it is still wise to verify the actual wheels on the truck, especially if it has been restored, modified, or converted to a different wheel setup during its life.

The 1973 Jeep Truck Truck covers several sub-models, and they do not all share the same wheel-and-tire configuration. Some sub-models can use more than one primary fitment, and the overall range includes both 15-inch and 16-inch bias-ply sizes.

That variation means tire choice is not just a matter of picking a familiar-looking size. The buyer should confirm the truck's exact sub-model, check whether the current wheels are 15-inch or 16-inch, and then compare tire style, intended use, and construction options within the correct size family.

F78-15 is a primary bias-ply tire size for certain 1973 Jeep Truck Truck applications. It uses the older alphanumeric sizing system, so the size itself does not indicate a radial construction in this fitment; the primary tire type is bias-ply.

That matters because a buyer deciding between originality of construction and a radial alternative should not assume the same code covers both. A radial choice must be selected by its equivalent size, then checked against wheel width, overall dimensions, and clearance on the truck's actual 15-inch wheel setup.

F78-15 radial equivalents include 195R15, P205/75R15, P215/70R15, and 670R15 as a bias-look radial. H78-15 equivalents include 215R15, P225/75R15, P235/70R15, and 760R15 as a bias-look radial.

Those choices span an 80-series metric radial, a 75-series P-metric option, a lower-profile 70-series P-metric alternative, and a bias-look radial that keeps a more traditional appearance. The recommended rim-width ranges are 5-7 inches for F78-15 and 6-8 inches for H78-15, so wheel compatibility and vehicle clearance should be verified before switching.

Start by confirming that the truck uses a 15-inch size with a defined radial equivalent, because the radial-equivalent paths here apply to F78-15 and H78-15. Then compare the actual wheel width, rim diameter, tire dimensions, and the truck's available steering and fender clearance.

A construction change can also affect the truck's appearance and the feel of the vehicle on the road, so the decision should match the way the Jeep will be used. Wheel condition, suspension wear, and any previous modifications deserve a close look before changing from the original-style bias-ply setup.

The key factors are the correct primary size, the truck's actual rim diameter, and whether the tire needs to support a restoration-oriented look or a more utilitarian truck role. On this Jeep, that could mean choosing between 15-inch and 16-inch fitments, or between classic bias-ply styling and a radial-equivalent path on certain 15-inch sizes.

Once the size is settled, compare construction, sidewall style, tire series, and wheel-width suitability. A wide whitewall creates a very different presentation than a blackwall truck tire, and military, traction, or highway-style series may suit a different visual or use case than a standard classic bias-ply pattern.

The available sidewall styles for 1973 Jeep Truck Truck tires are primarily blackwall and wide whitewall. Which styles appear depends on the size, with truck-oriented patterns commonly offered as blackwalls and some classic bias-ply sizes also available with wide whitewall treatment.

That choice affects the truck's visual character more than its fitment, but it still needs to be made within the correct size and wheel setup. A blackwall usually leans toward a more functional or heavy-duty presentation, while a wide whitewall gives the truck a more restoration-oriented and period-style appearance.

Available brands for 1973 Jeep Truck Truck fitments include BFGoodrich, Firestone, Lester, Avon, Coker Classic, Tornel, and STA. The brand mix varies by size, so the choices for 700-16 differ from those for H78-15 or 750-16.

Brand selection is best used as one part of the decision rather than the only one. The more useful comparison points are whether the tire is built in the correct size, whether it matches the wheel dimensions on the truck, and whether its sidewall style and tire series fit the intended appearance and use.

A period-style 1973 Jeep Truck Truck usually starts with retaining the correct primary bias-ply size for the exact sub-model and wheel diameter. From there, the choice becomes whether the truck should wear a traditional blackwall truck tire, a wide whitewall classic bias-ply, or, on certain 15-inch sizes, a bias-look radial alternative.

The right answer depends on the truck's presentation goal. A work-truck or utility look may point toward military, traction, or highway-style blackwalls, while a more restoration-oriented build may lean toward a classic whitewall treatment. Exact originality questions are best checked against marque references or period vehicle documentation.

Tire construction can noticeably shape the visual impression of a restored 1973 Jeep Truck Truck. A bias-ply tire preserves the traditional vintage sizing language and sidewall character associated with the truck's era, while a radial equivalent can change the overall look even when the rim diameter stays the same.

That difference matters most on trucks being restored for a distinctly period-style presentation. Buyers who want a more original-feeling stance often stay with bias-ply construction, while those balancing appearance with a radial option usually focus on bias-look radial choices and careful dimensional checks before making the change.

Yes, modifications can affect tire fitment on a 1973 Jeep Truck Truck even when the replacement tire is in the correct primary size family. Aftermarket wheels, different wheel widths, suspension changes, lift or lowering changes, and body or steering alterations can all influence how much space the tire has.

That is especially important on a truck that may have changed hands and uses over several decades. The safest approach is to confirm the actual wheel diameter and width on the vehicle, then check steering clearance, fender clearance, and stance before moving to a new tire or a radial-equivalent alternative.

Before putting a 1973 Jeep Truck Truck back on the road, inspect wheel condition, valve stems, lug hardware, and the general condition of the steering and suspension. Tire pressure should be set correctly for the tire being used, and the new tires should be checked for proper seating and visible clearance at full steering travel.

Older trucks often reveal fitment or mechanical issues only after fresh tires are installed. A short, careful test drive followed by a second inspection can help catch rubbing, unusual wear patterns, vibration, or air loss early, before the truck is driven regularly or taken on a longer trip.

Collector-vehicle tires on a 1973 Jeep Truck Truck should be inspected regularly for cracking, bulges, cuts, uneven wear, and air loss, even if the truck is driven only occasionally. Low annual mileage does not stop tires from aging, and older utility trucks may spend long periods parked with weight resting in one position.

Storage conditions matter just as much as mileage. Keeping the truck away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition, and maintaining proper inflation helps protect both the tire and the wheel. Seasonal checks are a smart routine before any serious road use.
