Plymouth Satellite Tires

Plymouth Satellite models from 1971 through 1974 use six listed sizes: E78-14, F78-14, G78-14, H78-14, 855-14, and HR78-14. E78-14, F78-14, G78-14, and H78-14 appear across all four years, 855-14 is listed only for 1971, and HR78-14 appears only for 1973 and 1974. Every listed size uses a 14-inch rim, but the recommended rim-width range varies by size, with examples such as 4.50 to 7.00 inches for E78-14 and 5.50 to 8.00 inches for H78-14.

The practical takeaway is that Plymouth Satellite fitment is driven more by exact size and application than by wheel diameter, since all of these fitments stay on 14-inch wheels. Start with the car’s year, then compare the size already on the car, the wheel width, and any factory paperwork or restoration records so you can separate a true fitment from a later replacement choice.

On a Plymouth Satellite, 855-14 is a numeric bias-ply size used in the 1971 listings. The 855 is the nominal section width with the decimal omitted, a period sizing convention that predates modern metric labeling, and the 14 identifies the wheel diameter in inches. The listed 855-14 products fit 14-inch rims with a 5.50 to 6.00 inch rim-width range and are bias-ply tires.

That means 855-14 should not be treated as interchangeable with every other 14-inch size shown for Plymouth Satellite applications. If your car is a 1971 model and carries this size on its build records, wheel sticker, or long-established restoration, keep the wheel width and body clearance in mind before moving to a different alphanumeric size.

A 1971 Plymouth Satellite shows five tire sizes because the model line covered more than one configuration within the same year. The listed sizes for 1971 are F78-14, G78-14, 855-14, H78-14, and E78-14, all on 14-inch rims, so the split is not a wheel-diameter change. It is a same-year variation that points to differences such as trim level, body style, or intended duty rather than a single universal tire across every 1971 Satellite.

For an owner, that means year alone is not enough to choose correctly. A 1971 Plymouth Satellite should be checked against the existing wheel width, any original labels or paperwork, and the car’s exact body and equipment level so the tire size supports both proper appearance and proper fit inside the wheel opening.

Most listed Plymouth Satellite products are bias-ply tires in numeric or alphanumeric bias sizing, and those are the applications where a tube is generally required here. E78-14, F78-14, G78-14, H78-14, and 855-14 are all shown in bias-ply construction, while HR78-14 is the radial-format exception in the year listings. One E78-14 product is specifically marked tubeless, but that does not automatically make every bias-ply option in the size tubeless.

The safest approach is to treat the wheel and tire as a complete system rather than assuming all 14-inch Plymouth Satellite wheels are identical in sealing condition. If the car retains older wheels or you are aiming for a period-style bias-ply setup, verify the wheel type carefully and match the tire choice to how the car will actually be driven and shown.

A 1973 Plymouth Satellite can use E78-14, F78-14, G78-14, H78-14, or HR78-14, so confirmation starts with narrowing the car to its exact configuration. All of those sizes fit 14-inch wheels, but they represent different section widths and, in the case of HR78-14, a radial rather than a bias-ply format. The correct choice comes from matching the car’s year, trim, wheel width, and established factory-size reference rather than selecting by model name alone.

Begin with what is physically on the car now, especially if it is an older restoration with original-style wheels. Then compare that information with surviving labels, owner paperwork, restoration notes, or trusted marque references so you can decide whether the goal is strict authenticity, a period-style bias-ply replacement, or a later radial-style setup that still falls within the listed 1973 options.

Plymouth Satellite tire offerings here include wide whitewall, narrow whitewall, dual-white-stripe, and blackwall sidewall styles. G78-14 has the broadest style spread, including dual white stripe, narrow whitewall, and wide whitewall versions, while E78-14 includes both wide whitewall and blackwall options. That gives owners a meaningful choice between a cleaner performance look and a more dressy factory-era appearance.

Sidewall style matters because it changes the car’s character even when the size is correct. A lower-key blackwall or narrow whitewall usually suits more understated or utility-oriented presentations, while a wider whitewall or dual-stripe treatment better matches many period-restored street cars that carried more visual trim from the factory era.

Three brands appear in the available Plymouth Satellite tire selections: Coker Classic, BFGoodrich, and STA. Coker Classic supplies several whitewall bias-ply sizes, BFGoodrich appears in sizes such as G78-14 and 855-14 with narrow and dual-stripe whitewall treatments, and STA appears in E78-14 with blackwall offerings including Traxion and Transport Highway series. Brand choice here is tied closely to sidewall appearance and tire series, not just size.

That means an owner can narrow the search in two ways at once: first by correct size, then by the look and usage the car needs. A restoration focused on original-style visual impact may lean one way, while a more utility-driven or commercial-style presentation within the E78-14 options may point toward one of the STA blackwall offerings.

Plymouth Satellite tires here appear in four distinct series: Coker Classic Bias Ply, Silvertown Classic Bias Ply, Traxion, and Transport Highway. The first two are classic bias-ply passenger-car style offerings with period whitewall treatments, while Traxion and Transport Highway are blackwall bias-ply lines that lean toward heavier-duty or truck-style use, especially in E78-14. All four series stay within the 14-inch fitment range shown for the model.

For the buyer, the series name helps sort appearance and intended character more than basic fit. If the goal is a traditional restored-car look, the classic passenger series make the most sense, while the STA offerings better suit a functional blackwall presentation or a heavier-duty application where that style is appropriate for the specific Plymouth Satellite configuration.

A Plymouth Satellite should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, welders, ozone sources, and petroleum contamination. Clean the tires with mild soap and water only, keep inflation appropriate for storage, and avoid letting the car sit for long periods on damp concrete or bare ground. Bias-ply collector tires especially benefit from a stable environment because their shape can flat-spot when left loaded for extended periods.

If the Plymouth Satellite will sit for months at a time, move it occasionally or support it in a way that reduces prolonged stress on one contact patch. Owners who keep a show car on wide whitewalls should also cover the tires from light exposure, since appearance matters as much as service life on a low-use collector car.

Tires on a Plymouth Satellite should be inspected before each meaningful drive and more thoroughly at regular seasonal intervals. Check inflation, tread and shoulder wear, sidewall cracking, bead condition, age-related hardening, and any signs that the car has been stored under load too long. On bias-ply tires, also look for irregular wear or pull that may suggest alignment, suspension, or inflation issues that modern radial owners sometimes overlook.

Regular inspection matters because collector cars often accumulate little mileage while still aging continuously. A Plymouth Satellite that only sees occasional weekend use can develop tire issues from time, storage, and heat cycles rather than tread wear, so visual checks and periodic hands-on inspection should be part of the routine every time the car comes out of the garage.

Plymouth Satellite tires should be replaced when age, cracking, hardening, vibration, impact damage, or internal deterioration appear, even if the tread still looks deep. Collector-car tires often age out long before they wear out, and that is especially important with older-style bias-ply construction or any tire that has spent years carrying the weight of a parked car. Tread depth alone is not a reliable measure of remaining service life on a lightly driven classic.

An owner should think in terms of condition and age rather than mileage. If a Plymouth Satellite carries older tires of uncertain history, a close inspection by a tire professional familiar with collector vehicles is wise before regular road use, because visual appearance can stay acceptable long after the tire’s structure has started to degrade.

Plymouth Satellite original-style fitment within this year group is not a single tire across all cars, because multiple sizes were used from 1971 through 1974. The listed period-style options include E78-14, F78-14, G78-14, H78-14, 855-14, and later HR78-14, with series such as Coker Classic Bias Ply and Silvertown Classic Bias Ply representing the passenger-car side of the available choices. That spread reflects how trim and configuration could influence what belonged on a specific car.

For an accurate restoration, the best path is to match the tire to the exact year, body style, wheel width, and any surviving factory paperwork for the individual Plymouth Satellite. Marque literature and club judging standards are especially helpful when a year shows several possible sizes and more than one sidewall treatment that could look right at first glance.

Correct tire fitment can absolutely affect how a Plymouth Satellite is viewed in both restoration judging and the collector market. Judges and knowledgeable buyers often notice whether the car carries the right era-appropriate size, sidewall treatment, and construction style, especially on a visible B-body where wheel and tire proportions strongly influence stance. A tire that is merely close in diameter can still look wrong if the section width or sidewall style does not suit the car.

That does not mean every Plymouth Satellite must wear the same tire, because the listed years already show multiple legitimate sizes. It does mean the choice should be intentional: confirm the proper fitment for the exact car, then decide whether the priority is concours-style authenticity, a factory-stock street presentation, or a period-inspired look that remains visually credible.

A Plymouth Satellite restoration can plausibly use several sidewall styles from the available range, including wide whitewall, narrow whitewall, dual-white-stripe, and blackwall. The most appropriate choice depends on the specific year, trim, and presentation of the car rather than the model name alone. Wide whitewalls and dual-stripe treatments create a more formal early-1970s look, while blackwalls and narrower whitewalls better suit plainer or more performance-oriented appearances.

The right answer comes from matching the sidewall to the car’s exact personality and equipment. If the Plymouth Satellite is being judged, compare the tire style to period photos, original sales literature, and marque-club expectations; if it is a driver-quality restoration, choose the sidewall that preserves correct scale and era character once the car is sitting on its wheels.

A properly selected and properly maintained tire can be suitable for driving a Plymouth Satellite on public roads, but suitability depends on age, condition, construction type, and how the car is used. The available Plymouth Satellite choices here are mostly bias-ply designs, with HR78-14 representing the listed radial-format option for 1973 and 1974. A fresh collector tire in the correct size is very different from an older tire that still looks presentable but has hardened with age.

Road use should match the tire’s design and the car’s mechanical condition. A Plymouth Satellite used for local cruising and shows can work well on period-style tires when alignment, brakes, steering, and suspension are sorted, but owners should still leave wider margins for stopping, cornering, and wet-weather behavior than they would in a modern car.

Before driving a Plymouth Satellite, check tire inflation, visible sidewall condition, tread condition, wheel-nut security, and any sign of contact between the tire and the body or suspension. Because several sizes fit within the model run, it is also wise to confirm that all four tires match in size and construction unless the car was intentionally set up otherwise. Bias-ply tires deserve extra attention for flat-spotting after storage and for age cracks that can hide near the bead or whitewall edge.

A short pre-drive walkaround prevents many collector-car problems before they become roadside problems. On a Plymouth Satellite that has been sitting, the first few miles should be treated as a systems check, with attention to pull, vibration, brake feel, and any steering response that suggests the tires or front-end settings need another look.

A Plymouth Satellite on original-style collector tires should be driven at sensible, moderate road speeds that respect the car’s age, its suspension design, and the construction of the tires fitted to it. Bias-ply tires typically do not respond like modern performance radials, and even the listed radial-format HR78-14 should not be treated as if it turns the car into a contemporary highway machine. Appropriate speed is as much about mechanical margin and stability as it is about raw capability.

In practice, a Plymouth Satellite owner should drive within the comfort zone of the car rather than the posted limit alone. If the car feels unsettled, wanders, or reacts strongly to road grooves, reduce speed and reassess inflation, alignment, and tire selection, because the right pace for a classic is the one that preserves control and keeps the car enjoyable.
