1973 Plymouth Satellite Tires

A 1973 Plymouth Satellite can use E78-14, F78-14, G78-14, H78-14, or HR78-14, depending on the exact sub-model. The 6 Cyl. uses E78-14 or F78-14, the 8 Cyl. uses F78-14 or G78-14, and the Wagon uses H78-14 or HR78-14. Most of those are vintage alphanumeric bias-ply sizes, while HR78-14 is an alphanumeric radial.

The practical first step is identifying the car as a 6 Cyl., 8 Cyl., or Wagon before choosing any tire. Once that is confirmed, check the actual wheel diameter and the size already on the car, especially if the Satellite has had wheel changes during its life. That prevents mixing up a correct 14-inch fitment with a size that belongs to another version of the model.

The tire sizes used on the 1973 Plymouth Satellite are all built for a 14-inch rim. That applies across E78-14, F78-14, G78-14, H78-14, and HR78-14, even though the vehicle uses more than one tire size and more than one construction type within that shared rim diameter.

Knowing the wheel is 14 inches narrows the search, but it does not settle the fitment by itself. The remaining questions are which sub-model you have, whether the car is using a bias-ply or radial application, and whether the actual wheel width matches the tire you are considering. On a restored or modified car, checking the wheel stamp or measuring the wheel is worth the extra step.

The 1973 Plymouth Satellite covers several sub-models, and they do not all use the same tire size. The 6 Cyl., 8 Cyl., and Wagon each have their own fitment range, and the Wagon also introduces a primary radial size with HR78-14 alongside a larger bias-ply option. That is why the model name alone is not enough to choose a tire.

Multiple sizes do not mean any 14-inch tire in the range can be used interchangeably. Each size carries its own width and profile family, and the correct choice starts with the exact sub-model and current wheel setup. If the Satellite has replacement wheels, suspension changes, or a long service history, compare what is on the car now with the intended tire before making a final selection.

F78-14 is a bias-ply tire size on the 1973 Plymouth Satellite. It uses the vintage alphanumeric bias-ply system rather than a radial designation, and it appears on both the 6 Cyl. and 8 Cyl. versions of the car. In contrast, HR78-14 is the model's primary alphanumeric radial size.

That distinction matters because staying with F78-14 preserves the original-style construction used in that application, while moving to a radial means evaluating an equivalent rather than another primary fitment. Construction choice affects appearance, wheel compatibility, and the overall character of the car. It is wise to confirm the wheel width and the intended use of the Satellite before changing from the original-style bias-ply format.

Radial equivalents for F78-14 include 195R14 as an 80-series metric radial, P205/75R14 as a 75-series P-metric radial, and P215/70R14 as a 70-series P-metric radial. A 750R14 bias-look radial is also available for F78-14. The recommended rim-width range for those equivalents is 4-6 inches.

Those sizes give different ways to approach a radial conversion, from a more traditional metric radial format to a lower-profile P-metric alternative and a bias-look radial for a more vintage presentation. None should be treated as an automatic swap just because the rim diameter matches. Wheel width, tire dimensions, and clearance at the fender and steering components should all be checked before making the change.

That depends on the exact sub-model and the result you want from the car. Most 1973 Plymouth Satellite fitments are primary bias-ply sizes, while the Wagon also includes a primary radial fitment in HR78-14. Bias-ply tires keep the original-style sizing system and period presentation, while radial options come into play either as a primary Wagon fitment or as an equivalent for certain bias-ply sizes.

A restoration-oriented car may stay with the original-style bias-ply format for appearance and authenticity of feel, while a driver may lead you toward a carefully checked radial alternative. The safest approach is to match the sub-model first, then decide whether preserving the original construction or evaluating an equivalent better suits the car's use. Wheel width and clearance deserve close attention before any conversion.

Start with the exact sub-model, because the 1973 Plymouth Satellite does not use one universal tire size. The correct choice begins with the right 14-inch size for the 6 Cyl., 8 Cyl., or Wagon, then moves to construction type, since the model range includes both bias-ply and radial applications. After that, sidewall style and tire series become the main selection points.

A buyer focused on restoration may prioritize a traditional bias-ply look and a whitewall style that suits the car's era, while a road-use-focused owner may spend more time comparing equivalent radial paths where available. It also helps to compare wheel-width compatibility and, where shown, load capacity at its stated pressure. Those details help narrow the choices without treating every 14-inch option as interchangeable.

Sidewall styles available for 1973 Plymouth Satellite tires include blackwall, narrow whitewall, dual-white-stripe, and wide whitewall, depending on the tire size. E78-14 includes blackwall and wide whitewall choices, G78-14 adds narrow whitewall and dual-white-stripe options, and F78-14 and H78-14 are represented here with wide whitewall offerings.

That makes sidewall style one of the biggest appearance decisions once the correct size is established. A wide whitewall pushes the car toward a more traditional early-1970s presentation, while blackwall or narrower stripe treatments create a different visual balance. Since sidewall availability changes by size, choose the correct fitment first and then see which appearance options exist within that exact tire size.

Brands available in 14-inch 1973 Plymouth Satellite fitments include Coker Classic, BFGoodrich, and STA. Brand choice varies by size, with Coker Classic appearing across several sizes, BFGoodrich represented in G78-14, and STA appearing in E78-14. The available tires also span different series, including Coker Classic Bias Ply, Silvertown Classic Bias Ply, Traxion, and Transport Highway.

Brand matters most when it changes the type of tire you can actually buy in the size your Satellite uses. Some sizes offer a broader mix of sidewall treatments and series, while others are much narrower in choice. Instead of starting with a favorite brand, confirm the correct size and construction first, then compare the brands that are actually available in that specific fitment.

A period-style 1973 Plymouth Satellite usually starts with the original-style primary size for the exact sub-model and, in most cases, a bias-ply construction. E78-14, F78-14, G78-14, and H78-14 all keep the vintage alphanumeric bias-ply format that suits the car's era. The Wagon is the exception, since it can also use the primary HR78-14 radial size.

After the correct size is established, the choice becomes one of presentation as much as fitment. Whitewall width, stripe treatment, and tire series all change how the car sits visually without changing the sub-model's basic size requirement. For an exact originality target, compare your tire choice with marque-club guidance, photos, or build-specific documentation rather than assuming any available sidewall style is automatically correct.

Tire construction changes the visual character of a restored 1973 Plymouth Satellite as much as the sidewall treatment does. A bias-ply tire preserves the vintage alphanumeric format used across most of the model range, which tends to suit a traditional restoration theme. A radial can shift the look toward a later replacement-style presentation unless the car is a Wagon using the primary HR78-14 radial fitment.

That is why construction should be considered part of the restoration decision, not just a driving decision. Owners trying to recreate a strong period impression often begin with the original-style construction, then choose among wide whitewall, narrow whitewall, or stripe treatments where available. Owners more concerned with road use may still consider radial equivalents, but the visual effect should be part of that decision.

Yes, modifications can change tire fitment on a 1973 Plymouth Satellite even when the tire size itself is correct for the model. Aftermarket wheels, different wheel widths, altered offset, suspension changes, lowering, or body work can all affect how a 14-inch tire sits in the wheel opening. That matters with both original-style bias-ply sizes and radial alternatives.

A Satellite that has been modified should be checked at full steering lock and through normal suspension travel before settling on a tire. Measure the actual wheel, confirm the diameter, and compare the intended tire with the space available around the fender lip and inner chassis areas. Those steps are especially important when switching from one size family or construction type to another.

Before driving a 1973 Plymouth Satellite on new tires, inspect the wheels for damage, confirm the wheel diameter and width, and make sure the tire size matches the exact sub-model. Then look over suspension and steering components for looseness or wear that could affect tracking, clearance, or uneven tire behavior once the car is back on the road.

It also helps to verify inflation, valve condition, and clear space around the tire at the fender and chassis. On a collector car, old alignment issues, tired bushings, or sagging springs can show up quickly after a tire change. A careful walkaround after the first short drive can reveal rub marks, air loss, or any sign that the chosen size needs to be rechecked.

Collector-car tires on a 1973 Plymouth Satellite should be inspected regularly for pressure loss, sidewall cracking, cuts, bulges, and uneven tread wear, even if the car is driven only occasionally. Low annual mileage does not stop rubber from aging, and long periods of storage can hide problems until the car is put back on the road.

Good maintenance also means keeping the car stored away from prolonged sunlight, moisture, heat, and ozone sources when possible. Move the vehicle periodically so the tires are not sitting in one position for long stretches, and check inflation before each drive rather than assuming it is unchanged. On a Satellite that sees seasonal use, a pre-drive inspection is as important as routine cleaning and detailing.
