1973 Ford 500 & Squire Tires

The 1973 Ford 500 & Squire uses four primary 14-inch bias-ply tire sizes: F78-14, G70-14, G78-14, and H78-14. The correct one depends on the wagon's exact covered sub-model, since the engine and suspension configuration affects which of those primary sizes apply.

That means the first step is not choosing a brand or sidewall style, but confirming which sub-model the car falls under and verifying the wheel setup currently on the vehicle. A wagon that has been fitted with different wheels over the years may need the actual rim diameter and width checked before moving ahead with either a bias-ply replacement or a radial-equivalent comparison.

The primary tire sizes for the 1973 Ford 500 & Squire all use a 14-inch rim diameter. That stays consistent across F78-14, G70-14, G78-14, and H78-14, even though the size family changes from one configuration to another.

Rim diameter is only part of the fitment picture, so it is smart to confirm wheel width as well before selecting a tire. Some of the available bias-ply products and radial-equivalent ranges are meant for different width windows, and that can affect whether a particular tire is a sensible match for the wheels currently on the wagon.

More than one tire size applies because the covered 1973 Ford 500 & Squire sub-models do not all share the same setup. One group uses G70-14, G78-14, or H78-14, while the heavy-duty suspension 302 configuration uses F78-14, G78-14, or H78-14.

That variation makes sub-model identification important before comparing products. It also explains why one owner may be looking at redline or raised white letter G70-14 options, while another may need a more traditional whitewall F78-14 or H78-14. Matching the wagon's exact configuration keeps the search focused on the sizes that actually belong in its fitment range.

G78-14 is a primary bias-ply tire size for the 1973 Ford 500 & Squire. It uses the vintage alphanumeric sizing system rather than a modern metric radial format, and it is one of the 14-inch original-style fitments shared across the covered sub-model range.

Keeping G78-14 in bias-ply form supports a traditional look and maintains the original sizing language of the vehicle. Owners considering a radial alternative should treat that as a separate fitment decision, since the equivalent radial choices use different size conventions and should be checked against wheel width, overall dimensions, and available clearance before making the change.

Radial equivalents for G78-14 include 205R14 as an 80-series metric radial, P215/75R14 as a 75-series P-metric radial, P225/70R14 as a 70-series P-metric radial, and 800R14 as a bias-look radial. Those options keep the same 14-inch rim diameter while offering different sizing formats and profile conventions.

Each of those alternatives should be evaluated as an option rather than an automatic replacement. The recommended rim-width range is 5 to 7 inches, which gives a helpful starting point, but wheel width, tire clearance, and the wagon's present stance still deserve a close look before moving from the original-style G78-14 bias-ply setup to a radial package.

Start by matching the wagon's primary bias-ply size to the correct radial-equivalent family for that exact fitment. For example, F78-14, G70-14, G78-14, and H78-14 each have specific metric or P-metric radial alternatives, and some also have bias-look radial options that preserve a more traditional visual presentation.

A careful conversion check should include actual wheel diameter and width, the recommended rim-width range for the candidate equivalent, and the available space at the fenders and steering components. It also helps to consider how the car is used, since a restoration-minded owner may value original-style appearance differently than an owner focused mainly on regular road miles.

Choosing a G78-14 tire starts with confirming that G78-14 is one of the primary sizes for the wagon's exact sub-model. From there, the main differences come from presentation and product character, since this size is available in bias-ply form with narrow whitewall, dual white stripe, and wide whitewall styles across BFGoodrich and Coker Classic offerings.

A buyer comparing G78-14 options should also pay attention to wheel compatibility and the intended look of the car. A formal wagon restoration may lean toward one whitewall treatment, while a preserved driver may call for another. Keeping the size correct comes first, then choosing the sidewall style and series that best suits the vehicle's appearance goals.

Sidewall choices for the 1973 Ford 500 & Squire vary by tire size and include redline, raised white letter, blackwall, pin white stripe, dual white stripe, narrow whitewall, and wide whitewall. G70-14 carries the broadest muscle-era style spread, while G78-14, H78-14, and F78-14 lean more toward traditional whitewall presentations.

That makes sidewall selection as much an appearance decision as a fitment one, but only after the correct size has been confirmed. A wagon with a more sporty period feel may suit G70-14 redline or raised white letter styling, while a more formal full-size restoration often points buyers toward one of the whitewall treatments in the other primary sizes.

The available brands for 1973 Ford 500 & Squire tire fitments include Firestone, Goodyear, BFGoodrich, and Coker Classic. Brand availability depends on the exact size, with G70-14 offering Firestone and Goodyear choices, G78-14 offering BFGoodrich and Coker Classic, and H78-14 and F78-14 appearing in Coker Classic form.

Brand should be compared alongside the actual tire series, sidewall treatment, and wheel compatibility rather than used as the only deciding factor. Since the available assortment changes from one size to another, the right approach is to confirm the wagon's correct fitment first and then compare the brands that exist within that exact size range.

A period-style choice starts with the correct primary size for the wagon's exact sub-model: F78-14, G70-14, G78-14, or H78-14 in bias-ply construction. From there, the visual direction changes by size, with G70-14 offering redline, raised white letter, blackwall, and pin stripe looks, while the other sizes lean more toward whitewall treatments.

That decision usually comes down to how the car is being presented rather than one universal answer. A more formal full-size wagon often looks different on a whitewall than on a sporty redline tire, and owners seeking strict originality should compare their choice with marque references, build history, or restoration documentation before settling on a final sidewall style.

On a restored 1973 Ford 500 & Squire, bias-ply construction preserves the vehicle's original-era sizing language and the traditional tire profile associated with these 14-inch fitments. A radial equivalent changes the sizing format and can shift the visual impression, especially when the alternative uses modern metric or P-metric markings.

That does not make one approach universally right or wrong, but it does make the restoration goal important. An owner focused on traditional presentation may stay with the primary bias-ply size, while someone planning more regular road use may explore a radial equivalent or a bias-look radial after confirming wheel width and making sure the overall fit remains appropriate.

Yes, modifications can affect tire fitment on a 1973 Ford 500 & Squire even when the chosen tire matches one of the correct primary sizes. Aftermarket wheels, suspension changes, altered ride height, or body repairs can all change the space available around the tire and the way the wheel sits in the opening.

That is why it helps to inspect the actual wagon before ordering tires, especially if its history is uncertain. Checking wheel diameter, wheel width, and visible clearance at the fenders and steering components can prevent problems later. A sub-model may have the right size range on paper, but the car's current setup still needs to support that choice.

Before putting regular road miles on a 1973 Ford 500 & Squire with new tires, inspect the wheels for proper diameter and condition, verify that the tires are seated correctly, and make sure inflation matches the tire's intended setup. It is also wise to look over suspension and steering components on a large, older wagon.

A short, careful test drive can reveal rubbing, pull, vibration, or other issues that deserve attention before longer use. Owners should also keep an eye on air retention and inspect the sidewalls and tread periodically, since collector vehicles often sit for long periods and can develop age-related issues even when they are not driven very much.

Collector-car tires on a 1973 Ford 500 & Squire should be maintained with regular pressure checks, visual inspections, and periodic movement of the vehicle to avoid long static loading. Whether the wagon wears F78-14, G70-14, G78-14, or H78-14, attention should be paid to cracking, cuts, bulges, uneven wear, and slow air loss.

Storage conditions matter just as much as mileage on a low-use wagon. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition over time. It also helps to recheck the tires before any longer drive, since a vehicle that has been parked for weeks or months may need a fresh inspection.
