1978 Plymouth Fury Tires

The 1978 Plymouth Fury uses four primary tire sizes across its covered applications: 215R15, F78-15, G78-15, and H78-15. The correct size depends on the exact sub-model, with the Wagon using 215R15 radial or H78-15 bias-ply, the 225/318/360-engine models using F78-15 or G78-15 bias-ply, and the 400-engine models using G78-15 or H78-15 bias-ply.

That means the first job is identifying the actual version of the car rather than choosing by appearance alone. All of these sizes are built around a 15-inch rim, but the size family and construction type still need to match the vehicle's setup. If the car has been modified or has replacement wheels, verify the current wheel width and clearance before settling on a final tire choice.

The covered tire fitments for the 1978 Plymouth Fury use a 15-inch rim diameter. That applies across the radial 215R15 size as well as the F78-15, G78-15, and H78-15 bias-ply sizes, so the wheel diameter stays consistent even though the tire sizing system changes between applications.

Rim diameter is only one part of the fitment picture, so it should not be treated as the only check. A 15-inch wheel can still vary in width, and width matters when comparing bias-ply tires with radial equivalents or choosing among different product specifications. On an older full-size car, confirming the actual wheel dimensions on the vehicle is especially important if the wheels are not original to the current setup.

The 1978 Plymouth Fury has more than one tire size because fitment varies by sub-model and engine application. The Wagon uses a different fitment mix than the sedan-based engine-specific versions, and the size range includes both radial and bias-ply construction depending on the exact configuration.

That variation means the tire decision starts with vehicle identification, not just a quick look at the current sidewall. A previous owner may have changed wheels or substituted a different size over the years, so the safest path is to confirm the sub-model first and then compare the tire on the car with the wheel diameter and the appropriate fitment family before replacing anything.

H78-15 is a bias-ply tire size for the 1978 Plymouth Fury. It appears as a primary fitment on Wagon and 400-engine applications, using the vintage alphanumeric bias-ply sizing system rather than a modern metric radial format.

That matters because a buyer choosing H78-15 is usually deciding whether to stay with the original construction type used in that fitment family or to consider a radial equivalent separately. Keeping the bias-ply size preserves the traditional sizing convention and period-style presentation, while any move to a radial should include checks for wheel width, overall dimensions, and clearance at the steering and suspension points.

Radial equivalents for F78-15 on a 1978 Plymouth Fury include 195R15 as an 80-series metric radial, P205/75R15 as a 75-series P-metric radial, P215/70R15 as a 70-series P-metric radial, and 670R15 as a bias-look radial. The recommended rim-width range attached to these equivalents is 5 to 7 inches.

Each of those sizes represents a different radial format, so the choice is not just about changing construction. The 195R15 keeps a traditional metric radial convention, the two P-metric sizes introduce different profile families, and the 670R15 is aimed at a more vintage visual character. Before converting, compare the selected tire with the actual wheel width and check the car for clearance around the fenders and steering range.

The answer depends on which primary fitment belongs on the car and what the finished vehicle is meant to be. The 1978 Plymouth Fury includes both bias-ply and radial primary fitments across its covered applications, and the bias-ply sizes F78-15, G78-15, and H78-15 also have radial-equivalent options for buyers considering an alternative construction.

A bias-ply choice usually suits an owner who wants to stay within the original sizing style and keep a traditional look. A radial-equivalent path can be considered when road-use priorities point in that direction, but the switch should be treated as a fitment change rather than an automatic substitute. Wheel width, vehicle clearance, and the car's current setup all deserve confirmation before making the change.

Start with the correct primary size for the exact 1978 Plymouth Fury sub-model, since this car uses 215R15, F78-15, G78-15, and H78-15 depending on configuration. After size is confirmed, the next decisions are construction type, sidewall style, and whether the car is being kept in a traditional bias-ply format or evaluated for a radial-equivalent alternative.

Product details matter once the fitment is narrowed down. Some available choices focus on a wide whitewall presentation, while others use a plain blackwall truck-style look. Rim-width compatibility can also vary by size, so it helps to compare the wheel on the car against the tire being considered. That approach keeps appearance, fitment, and intended use working together instead of solving only one part of the decision.

The available sidewall styles for covered 1978 Plymouth Fury products include wide whitewall and blackwall. In G78-15 and H78-15, Coker Classic offerings use wide whitewall styling, while STA products use blackwall construction with a more utilitarian presentation.

That gives the buyer a meaningful appearance decision once the correct size is established. A wide whitewall can push the car toward a more restoration-oriented full-size passenger look, while a blackwall can create a plainer and more functional visual effect. Sidewall style should still come after fitment confirmation, since the right look only works when the tire size, construction, and wheel compatibility all suit the specific Fury application.

Coker Classic and STA offer applicable tires for the 1978 Plymouth Fury in the available G78-15 and H78-15 product range. The Coker Classic products are part of the Coker Classic Bias Ply series, while the STA options appear in the Traxion and Super Traxion lines.

Brand choice here is less about ranking one name over another and more about matching the product character to the car. Coker Classic options emphasize traditional whitewall passenger-car styling, while the STA offerings in these sizes are blackwall tires with military and truck-oriented attributes. Once the correct size is verified, compare sidewall presentation, tire series, rim-width specification, and the overall look you want the Fury to carry.

A period-style 1978 Plymouth Fury starts with the correct primary size for the exact sub-model, then stays within the construction and visual character that suit the finished car. For many restoration-oriented builds, that means looking closely at the alphanumeric bias-ply sizes F78-15, G78-15, or H78-15, while the Wagon may also involve the 215R15 radial fitment.

After the fitment is confirmed, the appearance decision becomes more specific. A wide whitewall can give the Fury a more formal late-1970s full-size presentation, while a blackwall pushes the look in a plainer direction. If exact originality matters beyond general period style, the smartest next step is to compare the tire choice against authoritative Plymouth literature, marque references, or other vehicle-specific restoration sources.

Tire construction changes more than the internal build of the tire on a restored 1978 Plymouth Fury; it also influences how the car reads visually. The bias-ply sizes used on many Fury applications carry the vintage alphanumeric sizing style, while the radial options and radial equivalents introduce a later metric or P-metric presentation.

That difference matters on a large late-1970s Mopar because the tire is a visible part of the car's stance and personality. A bias-ply setup usually supports a more traditional restoration-oriented look, while a radial equivalent can shift the visual impression even when the wheel diameter remains the same. Sidewall treatment adds another layer, so construction and sidewall style are best chosen together rather than as separate decisions.

Yes, modifications can affect tire fitment on a 1978 Plymouth Fury even when the car still uses a 15-inch wheel. Aftermarket wheels, changes in wheel width, altered ride height, suspension work, or body clearance changes can all influence whether a given primary size or radial-equivalent option is still appropriate for the car's current setup.

That is especially important on a car with multiple primary sizes and both bias-ply and radial pathways. A Fury that no longer sits or steers like a stock example may need closer checks at the fender edges, steering sweep, and suspension travel before a replacement tire is chosen. Verifying the actual wheel dimensions on the vehicle is usually the best starting point when modifications are part of the picture.

Before driving a 1978 Plymouth Fury on new tires, inspect the wheels for correct diameter and general condition, confirm that the tires are mounted in the proper size, and make sure inflation is set appropriately for the tire in use. It also helps to look over suspension and steering components so the new tires are not being asked to work with worn or unstable hardware.

A short, careful test drive is a smart follow-up on a collector-era full-size car. Listen for rubbing, check clearance at full steering lock, and watch for any unusual pull or vibration that might point to a setup problem rather than a tire issue. After the first miles, recheck air pressure and give the tires another visual inspection to confirm that everything is settling in normally.

Collector-vehicle tire care for a 1978 Plymouth Fury starts with regular pressure checks and frequent visual inspection, even if the car is driven only occasionally. Bias-ply and radial tires alike should be watched for cracking, bulges, cuts, uneven wear, and slow air loss, since age and storage conditions can matter as much as mileage on a low-use full-size car.

Storage habits make a real difference over time. Keeping the Fury away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the rubber, and moving or driving the car periodically can help prevent long stationary periods from becoming part of the tire's wear story. Before any longer outing, a close walk-around and pressure check are simple steps that can prevent avoidable problems.
