The 1984 Plymouth Conquest arrived during the rise of turbocharged, import-flavored sport coupes, giving Plymouth buyers a sharp-edged alternative to more conventional domestic performance cars. Its styling and road manners place tire choice at the center of both appearance and drivability. This model uses radial tires, with 195/70R14 and 215/60R15 fitments appearing on the 1984 Plymouth Conquest Base. That opens the door to very different presentations, from a straightforward blackwall sport radial to 15-inch options with wide whitewall, redline, raised white letter, and vintage-inspired performance series. The right choice starts with confirming which wheel diameter is on the car and then matching the tire to the way the Conquest is being preserved or driven.
Which Tire Size Is Right for The 1984 Plymouth Conquest
The 1984 Plymouth Conquest uses two primary tire sizes, and the first thing to confirm is wheel diameter. One fitment is a 195/70R14 radial on a 14-inch rim, while the other is a 215/60R15 radial on a 15-inch rim. Because the Base sub-model can use either setup, the real decision starts with checking the wheels currently on the car and then choosing the tire style, brand, and series that best suits its intended look and use.
A 195/70R14 uses a 195-millimeter section width, a 70-series aspect ratio, radial construction, and a 14-inch rim diameter. On the 1984 Plymouth Conquest, this is a modern metric radial fitment that suits buyers keeping the car on its 14-inch wheel setup. Available choices in this size center on a blackwall presentation, with Dunlop's Sport Classic giving the size a distinctly sporty, era-appropriate character. This size makes sense when the car is already equipped with 14-inch wheels and the goal is to retain that configuration rather than move to a different rim diameter.
A 215/60R15 uses a 215-millimeter section width, a 60-series profile, radial construction, and a 15-inch rim diameter. For the 1984 Plymouth Conquest, this size brings the broadest range of tire choices, including blackwall, wide whitewall, redline, and raised white letter sidewalls. Brands in this fitment include American Classic, BFGoodrich, Dunlop, Avon, and Vredestein across series such as Asymmetrical Tread, Radial TA, Sport Classic, CR6ZZ, and Sprint Classic. It is the size to evaluate when the car has 15-inch wheels and the owner wants more variety in appearance and tire character.
Sub-model fitment is straightforward here because the covered 1984 Plymouth Conquest Base can use either of the two primary radial tire sizes. What matters most is not trim identification, but confirming whether the car is on 14-inch or 15-inch wheels before choosing a tire.

Best 1984 Plymouth Conquest Tires for Sale
Available 1984 Plymouth Conquest tires range from a Dunlop Sport Classic blackwall in 195/70R14 to a wider 215/60R15 selection from American Classic, BFGoodrich, Dunlop, Avon, and Vredestein. The 15-inch choices vary by tire series, sidewall treatment, and rim-width specifications.
These FAQs focus on the two tire sizes used on the 1984 Plymouth Conquest, the difference between its 14-inch and 15-inch wheel setups, and how to choose among the available radial tires for fitment, appearance, and road use.
Tire Size & Fitment
What tire size fits a 1984 Plymouth Conquest?
The 1984 Plymouth Conquest uses two primary tire sizes: 195/70R14 and 215/60R15. Both are radial tire fitments, and the 1984 Plymouth Conquest Base can be equipped with either size depending on the wheel setup on the car.
That means tire selection starts with the wheels actually installed rather than the model name alone. A 14-inch wheel takes the 195/70R14 fitment, while a 15-inch wheel uses 215/60R15. Checking the wheel diameter before ordering is especially important on cars that may have had wheel changes over the years.
What size rim does a 1984 Plymouth Conquest use?
A 1984 Plymouth Conquest can use either a 14-inch rim or a 15-inch rim, depending on which tire size is on the car. The 195/70R14 fitment uses a 14-inch rim, and the 215/60R15 fitment uses a 15-inch rim.
Rim diameter is the first fitment detail to confirm because the two tire sizes are not for the same wheel. After verifying diameter, it is also worth checking wheel width against the tire being considered, particularly in 215/60R15 where individual products carry their own rim-width specifications.
Why does the 1984 Plymouth Conquest have more than one tire size?
The 1984 Plymouth Conquest appears with two radial tire sizes because the car can be found with either a 14-inch or 15-inch wheel setup. That is why both 195/70R14 and 215/60R15 belong to this exact year and model.
The practical takeaway is simple: do not choose a tire by year and model alone when two rim diameters are in play. Measure the wheel, confirm the current setup, and then compare the available tires within that size by sidewall style, brand, and other fitment details that matter to your car.
Choosing the Right Tire
What should I consider when choosing a 1984 Plymouth Conquest tire?
Start with the correct size for the wheels on the car: 195/70R14 for a 14-inch setup or 215/60R15 for a 15-inch setup. From there, compare the available radial tires by construction details, sidewall style, brand, tire series, and any rim-width or load information tied to the product.
The best choice depends on how the Conquest is being used and presented. A blackwall sport tire gives a different look than a redline, wide whitewall, or raised white letter option, and the broader 215/60R15 selection offers more room to tailor the car's appearance without changing the primary fitment size.
What sidewall styles are available for 1984 Plymouth Conquest tires?
Sidewall choices for the 1984 Plymouth Conquest include Blackwall, Wide Whitewall, Redline, and RWL, depending on tire size and product selection. The 195/70R14 offerings center on a blackwall presentation, while 215/60R15 opens up the broader range of sidewall treatments.
That variety matters because sidewall style changes the car's visual character even when the tire size stays correct. A blackwall keeps the look restrained and sporty, while redline, wide whitewall, or raised white letter tires create a more assertive or restoration-minded presentation on a Conquest running 15-inch wheels.
What brands offer tires for the 1984 Plymouth Conquest?
Tires for the 1984 Plymouth Conquest are available from Dunlop, American Classic, BFGoodrich, Avon, and Vredestein. Dunlop covers both fitment sizes, while the larger 215/60R15 size brings the widest spread of brands and product styles.
Brand choice should be weighed alongside the actual tire series, sidewall appearance, and wheel compatibility rather than treated as a shortcut by itself. A Conquest kept close to a period-style sport look may point one way, while a car being tailored for a more distinctive sidewall treatment may point another.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Plymouth Conquest?
A period-style 1984 Plymouth Conquest starts with keeping the correct primary size for the wheels on the car, either 195/70R14 or 215/60R15. From there, the choice becomes one of presentation, with blackwall tires offering a restrained sport-coupe look and 15-inch options adding redline, raised white letter, or wide whitewall alternatives.
Appearance goals should guide the final selection as much as the raw size. Buyers aiming for a preservation-minded result often focus on tire series and sidewall treatment that feel right for the car's mid-1980s personality, while exact originality questions are best checked against marque-specific historical references and surviving examples.
How does tire construction affect the appearance of a restored 1984 Plymouth Conquest?
On the 1984 Plymouth Conquest, construction does not create a bias-ply versus radial decision because the primary fitments are radial. The visual difference comes more from size, tire series, and sidewall treatment than from switching between fundamentally different construction types.
That keeps the restoration conversation centered on how the tire looks on the wheel and within the wheel opening. A blackwall sport radial gives a clean, understated finish, while redline, raised white letter, or wide whitewall versions in 215/60R15 shift the car toward a more customized or nostalgic visual statement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Plymouth Conquest?
Yes, modifications can affect tire fitment on a 1984 Plymouth Conquest even when the tire size itself is correct. Aftermarket wheels, changes in wheel width or offset, suspension alterations, and body changes can all influence clearance at the fender, steering, and suspension points.
That is especially important on a car with both 14-inch and 15-inch fitment paths. A Conquest that no longer has its original wheel setup should be checked carefully before choosing between 195/70R14 and 215/60R15, and any non-stock wheel should be matched against the tire's rim and clearance requirements.
What should I inspect before driving a 1984 Plymouth Conquest on new tires?
Before driving a 1984 Plymouth Conquest on new tires, inspect the wheels for correct diameter and condition, verify tire pressure, and make sure there is no rubbing at full steering lock or through suspension travel. It is also wise to look over the valve stems and confirm the tires are seated properly.
A broader pre-drive check helps on any collector-era car. Examine suspension and steering components for looseness, look for signs of uneven wear from previous alignment issues, and make sure older wheels are structurally sound. Those basic steps help the new tires perform as intended and reduce surprises on the road.
How should tires on a collector 1984 Plymouth Conquest be maintained?
Tires on a collector 1984 Plymouth Conquest should be checked regularly for pressure, tread condition, cracking, bulges, cuts, and slow air loss. Low-use cars can look fine at a glance, so routine inspection matters even when the vehicle is driven only occasionally.
Storage conditions also make a difference over time. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and occasional movement can reduce flat-spotting during long periods of inactivity. Before any longer drive, give the tires another visual and pressure check.
