Plymouth Conquest Tires

Plymouth Conquest uses four tire sizes across its 1984 to 1986 production span: 195/70R14, 215/60R15, 205/55R16, and 215/55R16. The 195/70R14 size is used in 1984 and 1985 on 14-inch rims, the 215/60R15 size appears from 1984 through 1986 on 15-inch rims, and the 205/55R16 and 215/55R16 sizes are both 1986 fitments for 16-inch rims. All listed Plymouth Conquest products are radial tires.

The practical step is to match both the year and the wheel diameter on the car before choosing a tire. A 1986 Plymouth Conquest is the most likely to create confusion because it can carry either a 15-inch or 16-inch fitment, so measuring the wheel or checking the existing sidewall is more important than relying on the year alone.

A 1986 Plymouth Conquest can show 205/55R16, 215/55R16, and 215/60R15 because that model year includes more than one wheel diameter. The 205/55R16 and 215/55R16 sizes are both 16-inch fitments, while 215/60R15 is a 15-inch fitment. That means the split is not just a small variation in width or aspect ratio; it reflects different wheel packages within the same year.

Start by confirming whether the car has 15-inch or 16-inch wheels, then narrow the size from there. If the car has 16-inch wheels, you still need to verify whether it belongs on the narrower 205/55R16 or the wider 215/55R16, using the current tire markings, factory literature, or a trusted marque specialist as the next step.

Plymouth Conquest uses three rim diameters across the years covered here: 14-inch, 15-inch, and 16-inch. The 14-inch size appears with 195/70R14 in 1984 and 1985, the 15-inch size appears with 215/60R15 from 1984 through 1986, and 16-inch sizes first appear in 1986 with both 205/55R16 and 215/55R16. The rim diameter is the last number in each metric tire size.

Wheel diameter is the first thing to confirm because a tire for one rim size cannot be safely fitted to another. On a Plymouth Conquest, that matters most when the car is a 1986 model or when wheels may have been changed over the years, since the model line spans several wheel diameters in a very short production window.

A 1986 Plymouth Conquest can take either 215/60R15, 205/55R16, or 215/55R16, so the correct size depends on the specific wheel package on the car. The quickest factual check is the wheel diameter itself: 15-inch wheels use 215/60R15, while 16-inch wheels use either 205/55R16 or 215/55R16. The sidewall on the current tire often confirms the existing fitment if the car is still on the right wheels.

Use the wheel diameter as the first filter, then compare the current tire size, wheel width, and the car’s intended presentation. If the car has already been restored or modified, treat the year listing as a starting point and verify against the actual hardware on the vehicle so you do not accidentally move from a correct 16-inch setup to a 15-inch tire, or vice versa.

Plymouth Conquest tires are available with several sidewall styles, including blackwall, wide whitewall, redline, and raised white letter. Blackwall choices appear across all four sizes, while wide whitewall and redline options are offered in selected 15-inch and 16-inch sizes, and raised white letter appears in 215/60R15. That gives Plymouth Conquest owners a mix of stock-leaning and custom-style visual options.

Sidewall choice affects the look of the car as much as the fitment itself. A blackwall tire usually suits a more factory-sport appearance, while redline, whitewall, or raised white letter tires can push the car toward a stronger period-custom or enthusiast look, so it helps to decide whether the goal is faithful presentation, a personal period style, or a more aggressive visual stance.

Plymouth Conquest tire offerings here come from American Classic, BFGoodrich, Dunlop, Avon, Michelin, and Vredestein. Brand coverage varies by size, with the widest spread appearing in 215/60R15 and more focused selections in the 14-inch and 16-inch sizes. The available series range from period-style collector radials to more performance-oriented radial lines.

Brand choice usually comes down to the look you want and how you plan to use the car. Owners aiming for a more original visual presentation often focus on sidewall style and classic-series appearance first, while drivers who want a sharper road-going feel may lean toward performance-oriented radial series in the 16-inch sizes.

Plymouth Conquest tires here include several distinct series, such as Sport Classic, Asymmetrical Tread, Radial T/A, CR6ZZ, Sprint Classic, g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Michelin SX MXX3 N2, and American Classic Radial. Some are clearly styled as collector-car radials with vintage-appropriate appearance cues, while others are more modern performance-oriented radial designs. The series split is especially noticeable between the period-looking 15-inch offerings and the sportier 16-inch choices.

That distinction matters because the right tire for a Plymouth Conquest is not always the most aggressive-looking option. If the car is being restored as an era-correct 1980s sport coupe, sidewall style and classic appearance may matter most, while a driver-focused car may benefit more from a performance-series radial that still matches the correct wheel diameter and overall size family.

A Plymouth Conquest should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, ozone sources, and petroleum contamination. Tire pressures should be maintained during storage, and the car should not sit for long periods with visibly underinflated tires. Clean, stable conditions matter more on collector-era cars because they are often driven infrequently and can spend long stretches parked.

If the car will sit for months, move it occasionally to change the contact patch or use methods that reduce flat-spotting stress. The goal is to protect both the tire structure and the appearance of the sidewalls, especially on specialty styles such as whitewalls, redlines, or raised white letter tires that are part of the car’s visual character.

Tires on a Plymouth Conquest should be inspected before regular driving and at least seasonally even if the car covers very few miles. The inspection should include air pressure, tread condition, sidewall cracking, bulges, punctures, uneven wear, and any sign that the tire has begun to age out structurally. Low annual mileage does not slow rubber aging in the same way it slows tread wear.

Collector cars often look fine visually while small defects are beginning to develop, so routine inspection is a habit worth building. A Plymouth Conquest that has spent time parked can also reveal suspension or alignment issues through odd wear patterns, and catching those early helps protect the next set of tires from premature damage.

Tires on a Plymouth Conquest should be replaced when age, cracking, hardening, bulging, impact damage, or other structural concerns appear, even if the tread still looks deep. Collector cars commonly age out their tires before they wear them out, particularly when the car is driven only occasionally. Visual appearance alone is not a reliable measure of serviceability once the tire has been on the car for years.

A practical rule is to treat time and condition as seriously as tread depth. If a Plymouth Conquest has been sitting on older tires through multiple seasons, have them evaluated during routine service and replace them when age-related deterioration starts to show, because the performance of an aging radial can fall off well before the tread is gone.

Plymouth Conquest used more than one original size family during its short production run, including 195/70R14 in 1984 and 1985, 215/60R15 from 1984 through 1986, and both 205/55R16 and 215/55R16 in 1986. All of the sizes listed here are radial formats, which suits the model’s 1980s sport-coupe character. There is no single one-size answer for every Plymouth Conquest because wheel diameter changed within the range.

For restoration work, the best approach is to start with the correct year and then verify the actual wheel package on the car. If originality matters for judging or presentation, use the car’s current wheel diameter, surviving original tires if present, and marque references together so the finished fitment reflects the specific Plymouth Conquest being restored rather than the broad model name alone.

Correct tire fitment can affect how a Plymouth Conquest is viewed in restoration, show, and enthusiast settings because wheel diameter, overall stance, and sidewall appearance all influence whether the car looks true to its era. A 14-inch, 15-inch, or 16-inch mismatch can alter the visual balance immediately, and an incorrect sidewall style can push the car away from a factory-sport presentation. On collectible 1980s cars, those details are noticed more than many owners expect.

If the goal is judged authenticity or top-tier presentation, match the tire size to the right year and wheel package first, then choose the sidewall treatment that best supports the car’s intended look. Marque clubs, period photos, and surviving original examples are useful references when deciding whether a blackwall, raised white letter, redline, or whitewall treatment suits a particular Plymouth Conquest.

Plymouth Conquest tires are available here in blackwall, wide whitewall, redline, and raised white letter styles, but blackwall is the most broadly available look across all sizes. Raised white letter appears in 215/60R15, while whitewall and redline options are offered in selected 15-inch and 16-inch fitments. That means the most restoration-oriented appearance for many cars will center on blackwall, while the other styles create a more customized period statement.

Choose the sidewall style that matches the story you want the car to tell. A carefully restored Plymouth Conquest usually benefits from a restrained look that respects its 1980s sport-coupe identity, while a period-custom build can justify whitewall or redline treatments if they complement the wheel choice and overall presentation without straying from the correct size family.

The listed Plymouth Conquest tires are radial designs in sizes that match the model’s known wheel diameters, so they are appropriate in principle for public-road use when fitted to the correct wheel and kept in sound condition. Safety depends on more than matching the sidewall size, however, because age, inflation, alignment, wheel condition, and suspension health all affect how the car behaves. A correct size on an unhealthy chassis is still a problem.

Before road use, make sure the tire size matches the wheel diameter exactly and that the rest of the car is equally ready to support modern traffic. On a Plymouth Conquest, that means giving special attention to any car that has sat for long periods, since low-use collector cars can hide brake, steering, and rubber-component issues even when the tires themselves look acceptable.

Before driving a Plymouth Conquest, check tire pressure, sidewall condition, tread wear, valve stems, and the wheel diameter-to-tire-size match. Also inspect for cracking, flat spotting after storage, and any sign of rubbing that could indicate the wrong size or a suspension problem. Because the Plymouth Conquest range includes 14-, 15-, and 16-inch fitments, confirming the basic wheel-and-tire match is especially important.

A short pre-drive inspection is worthwhile every time the car has been parked for a while. If anything feels vague, pulls to one side, vibrates, or reacts sharply over bumps, stop and inspect the car rather than assuming the issue will clear up, because an older performance-oriented coupe can quickly show tire or chassis faults once it is back at speed.

A Plymouth Conquest should be driven at speeds appropriate to the tire’s condition, the exact tire specification fitted, and the overall mechanical condition of the car rather than to the car’s performance reputation alone. Even with correct radial sizes, an older collector car may have aging suspension, brakes, or wheel components that limit safe real-world use. The tire sidewall specification is only one part of the equation.

The sensible approach is to build speed gradually after confirming pressures, condition, and balance, then judge the car honestly by how it behaves on the road. If the Plymouth Conquest is newly returned to service, treat early drives as shake-down miles and avoid sustained high-speed running until the full tire, wheel, brake, and chassis package has proven stable and predictable.
