1973 Jeep Commando Tires

The 1973 Jeep Commando is associated with three primary tire sizes: 7.35-15, F78-15, and H78-15. All three are bias-ply sizes built for 15-inch rims, and the covered Base, Roadster, Pickup and Wagon applications can be linked to those same size choices.

That makes the real first step confirming what is actually mounted on the vehicle now, rather than choosing by model name alone. Many surviving Commandos have had wheel or tire changes over time, so the sidewall size, rim diameter, and wheel width should all be checked before selecting a replacement tire.

The 1973 Jeep Commando uses 15-inch rims with its primary tire fitments. The associated sizes 7.35-15, F78-15, and H78-15 all share that same 15-inch rim diameter, even though the sizing systems differ between numeric and alphanumeric bias-ply formats.

Rim diameter is only part of the fitment picture, so it helps to confirm wheel width as well before changing tire size or construction. That becomes especially important when evaluating an H78-15 product with a stated rim-width range or when considering a radial equivalent for F78-15 or H78-15.

The covered 1973 Jeep Commando Base, Roadster, Pickup and Wagon applications are all associated with the same group of tire sizes: 7.35-15, F78-15, and H78-15. In other words, the sub-model grouping does not point to one exclusive size for each named version.

That broad overlap means sub-model name alone is not enough to choose a tire. The best approach is to inspect the vehicle’s present wheel and tire setup, then decide whether to stay with its current bias-ply size or compare that setup with an available radial-equivalent option where one exists.

F78-15 is a primary bias-ply tire size for the 1973 Jeep Commando. It uses the vintage alphanumeric sizing system rather than a modern metric radial format, so the original fitment language and the replacement decision both start from a traditional 15-inch bias-ply tire.

That does not prevent a radial alternative from being considered, but it helps define the choice clearly. Buyers preserving a period-style look often stay with bias-ply construction, while buyers evaluating more modern road manners may compare one of the radial-equivalent sizes after confirming wheel width, dimensions, and clearance.

F78-15 has four radial-equivalent options: 195R15, P205/75R15, P215/70R15, and 670R15. H78-15 also has four radial-equivalent options: 215R15, P225/75R15, P235/70R15, and 760R15. In each group, the metric and P-metric sizes offer different sizing conventions, while the 670R15 and 760R15 choices serve as bias-look radials.

Those equivalents are useful comparison points, not automatic substitutions. F78-15 corresponds to a recommended rim-width range of 5-7 inches, while H78-15 corresponds to 6-8 inches, and each alternative should be checked against the Commando’s actual wheel setup, section width needs, and available steering and body clearance.

Start by matching the radial candidate to the Commando’s existing primary size, since radial equivalents are available for F78-15 and H78-15 but not stated here for 7.35-15. Then confirm the wheel diameter remains 15 inches and compare the wheel width to the recommended range associated with the equivalent size you are considering.

Construction changes can also affect how the vehicle sits and clears under steering and suspension movement, especially on an older utility vehicle. A careful conversion should include checking the current wheel setup, front-end condition, suspension height, and body clearance rather than assuming that any radial equivalent will behave the same as the original bias-ply fitment.

The main considerations are the exact tire size already on the vehicle, the 15-inch wheel setup, and whether the goal is to keep a traditional bias-ply construction or evaluate a radial-equivalent option where one exists. On this Commando, the choice starts with 7.35-15, F78-15, or H78-15 rather than a one-size-fits-all answer.

Appearance and intended use matter next. A restoration-minded Jeep may lean toward a period-style bias-ply presentation, while a driver-focused vehicle may prompt a closer look at radial alternatives for F78-15 or H78-15. Wheel width, load needs, and the Jeep’s actual stance and clearance should all be part of the final decision.

Among the available H78-15 products, sidewall choices include wide whitewall and blackwall styles. The Coker Classic H78-15 options use a wide whitewall presentation, while the STA Traxion H78-15 uses a blackwall sidewall that suits a more work-oriented or utility-focused look.

That sidewall difference can change the personality of a 1973 Jeep Commando as much as the tire series itself. A whitewall tends to support a more restoration-oriented appearance, while a blackwall can feel more traditional for truck and off-road utility use. The best choice depends on the Jeep’s visual direction and how faithfully the owner wants to preserve a period-style presentation.

Current product choices for the 1973 Jeep Commando include Coker Classic and STA in H78-15. Those brands represent two different presentation paths within the same 15-inch bias-ply fitment, with Coker Classic centered on wide whitewall styling and STA offering the Traxion blackwall series.

Brand choice should still be filtered through the tire’s purpose on the vehicle rather than treated as a ranking exercise. It helps to compare sidewall style, tire series character, rim-width compatibility, and load specification, then decide which combination makes the most sense for the Commando’s appearance, utility role, and planned road use.

A period-style 1973 Jeep Commando usually starts with one of its original-format bias-ply sizes: 7.35-15, F78-15, or H78-15. Staying with bias-ply construction preserves the vintage sizing language and overall presentation that many restoration-oriented owners want on a classic Jeep utility vehicle.

Within that approach, the final choice depends on the exact setup already on the vehicle and the appearance you want to emphasize. H78-15 currently offers visible product variety, including wide whitewall and blackwall styles, while exact originality questions are best settled with model-specific historical references, surviving vehicle evidence, or marque-club guidance.

Tire construction affects more than ride characteristics on a restored 1973 Jeep Commando; it also changes the vehicle’s visual character. A bias-ply tire preserves the older sizing format and a more traditional profile, while a radial equivalent can introduce a more modern look even when it serves the same general fitment role.

That difference matters most when the Jeep is being restored with a strong period-style focus. A bias-look radial can help bridge the gap on F78-15 or H78-15, but it should still be viewed as a styling and construction alternative rather than the same thing as a true bias-ply tire.

Yes, modifications can affect tire fitment on a 1973 Jeep Commando even when the tire size itself appears correct. Aftermarket wheels, suspension lifts, lowering changes, altered springs, or body modifications can all change how a 7.35-15, F78-15, or H78-15 tire sits and clears during driving and steering movement.

A modified Commando should be checked for wheel diameter, wheel width, and available clearance at the fenders, suspension, and steering components before any replacement is chosen. That is especially important when moving from bias-ply construction to a radial equivalent, since the wheel and vehicle setup may no longer reflect original assumptions.

Before driving a 1973 Jeep Commando on new tires, inspect the wheels for correct diameter and overall condition, then confirm the tires are seated properly and inflated appropriately for their intended use. It also makes sense to look over the suspension, steering, and brake components on a vintage utility vehicle before heading out.

A short initial road check helps reveal rubbing, pulling, vibration, or clearance issues before they become bigger problems. Older collector vehicles also deserve a quick review of lug hardware, wheel fit, tread and sidewall condition, and any signs of air loss, especially if the Jeep has spent long periods parked between drives.

Collector-vehicle tire maintenance for a 1973 Jeep Commando starts with regular pressure checks, routine visual inspection, and attention to age-related deterioration. Even lightly used tires should be examined for cracking, bulges, cuts, flat spotting, uneven wear, and slow air loss, since storage time can be as important as mileage.

Storage conditions matter as well. Keeping the Jeep away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps protect the tires between drives, and moving the vehicle periodically can reduce long-term stress in one contact patch. A careful inspection before any longer trip is a smart habit with vintage bias-ply or radial-equivalent tires alike.
