1979 Chrysler Tire Fitment Guide

1979 Chrysler vehicles use six sizes across four model lines: FR78-15, GR78-15, and HR78-15 on the Cordoba; FR78-15 on the LeBaron; 205/75R15 and 225/70R15 on the New Yorker; and 195/75R15 plus 205/75R15 on the Newport. Every size in the range mounts on a 15-inch wheel. Where rim-width guidance is available from actual tire offerings, 195/75R15 generally fits 5.00- to 7.00-inch rims, 205/75R15 fits 5.50- to 7.50-inch rims, and 225/70R15 spans roughly 6.00 to 8.00 inches depending on the tire.

The practical takeaway is that a 1979 Chrysler owner needs to identify the model first, then confirm the exact size used on that model before choosing a product. Even though wheel diameter stays consistent at 15 inches, the alphanumeric and metric sizes are not interchangeable by name alone. Once the correct size is confirmed, the next decision is usually sidewall style and product character rather than searching across the whole Chrysler range.

FR78-15 is an alphanumeric radial tire size used on certain 1979 Chrysler Cordoba applications and on the 1979 Chrysler LeBaron. The final number, 15, is the wheel diameter in inches. The lettered size system was common in the 1970s, and the presence of the radial construction designation in the fitment history places it in Chrysler’s late-1970s shift toward modern radial sizing rather than earlier numeric bias-ply sizing.

For a buyer, FR78-15 matters because it is an era-correct late-1970s radial format, but it is still model-specific within the Chrysler lineup. A LeBaron owner should not assume that a Newport or New Yorker metric size is an equivalent replacement just because the rim diameter matches. If your car calls for FR78-15, stay focused on that alphanumeric radial size and compare products within that fitment rather than across the entire 1979 Chrysler range.

205/75R15 is a metric radial tire size used on the 1979 Chrysler New Yorker and 1979 Chrysler Newport. The 205 is the nominal section width in millimeters, the 75 is the aspect ratio, the R identifies radial construction, and the 15 is the wheel diameter in inches. In available 1979 Chrysler applications, this size appears in several whitewall and goldline versions and carries load figures up to 1598 pounds at 35 psi on multiple products.

That makes 205/75R15 one of the more versatile 1979 Chrysler sizes if your car is one of the models that uses it. It gives owners some freedom to tailor the look, from a cleaner goldline presentation to a more traditional whitewall treatment, without stepping outside the correct size family. The key is to confirm whether your specific New Yorker or Newport belongs in the 205/75R15 group before narrowing down sidewall style.

Sidewall style varies by size on 1979 Chrysler fitments that currently have product coverage. The 205/75R15 is available in wide whitewall, narrow whitewall, and goldline form, while 195/75R15 comes in both wide whitewall and narrow whitewall versions. The 225/70R15 leans toward a more performance-flavored late-1970s look with raised white letter choices, though a blackwall Michelin option also exists in that size.

For a restoration-minded owner, sidewall style often shapes the car’s visual personality as much as the size itself. A formal New Yorker or Newport usually looks more at home with a whitewall treatment, while a 225/70R15 New Yorker can also carry the sport-luxury attitude of an RWL tire. Matching the sidewall to the car’s intended appearance is often the final step after the correct size has already been confirmed.

Several brands cover 1979 Chrysler sizes that currently have tire offerings. BFGoodrich, Tornel, and American Classic make 205/75R15 options; Goodyear, Cooper, and Michelin cover 225/70R15; and Coker Classic plus American Classic cover 195/75R15. Those brands span a mix of traditional whitewall touring looks, raised white letter styles, and one blackwall high-speed-rated metric radial in the 225/70R15 group.

Brand choice usually comes down to the appearance and driving character you want within the correct size, not to switching sizes across different Chrysler models. A Newport owner looking for a formal whitewall presentation will naturally shop a different brand mix than a New Yorker owner considering a 225/70R15 RWL tire. Once model and size are settled, the brand conversation becomes much more useful and much less confusing.

Both Michelin XWX and Goodyear Polysteel cover the 225/70R15 size used on certain 1979 Chrysler New Yorker applications, but they present the car very differently. The Michelin XWX is a blackwall 225/70VR15 92W TL tire with a V speed rating, which carries a 149 mph ceiling, and it fits rims from 6.00 to 8.00 inches wide. The Goodyear Polysteel uses an RWL sidewall, carries a 1753-pound load rating at 35 psi, and is built around an 8-inch rim specification in this application.

A New Yorker owner choosing between them is really deciding between two period-correct late-1970s personalities within the same size. The Michelin favors a cleaner blackwall appearance with a higher formal speed classification, while the Goodyear leans into the raised-white-letter look associated with the era’s sportier image. Either way, the right starting point is confirming that your New Yorker actually uses 225/70R15 before comparing the two products.

Rim-width guidance is available for the metric radial sizes with current product coverage on 1979 Chrysler vehicles. The 195/75R15 generally fits rims from 5.00 to 7.00 inches wide, the 205/75R15 generally fits 5.50 to 7.50 inches, and the 225/70R15 ranges from about 6.00 to 8.00 inches depending on the specific tire. All of those sizes mount on 15-inch wheels, but the acceptable wheel width changes with the tire.

That matters because wheel diameter alone does not guarantee the best fit or sidewall shape. If your car has replacement wheels or non-original rims, compare the actual wheel width to the tire manufacturer’s approved range before making a final choice. Staying inside the correct width window helps preserve proper bead seating, sidewall profile, and overall stance on a 1979 Chrysler.

The metric radial products currently covering 1979 Chrysler applications are primarily tubeless-style tires, and the Michelin 225/70VR15 is explicitly marked TL. The other available metric sizes use modern radial sizing conventions without a tube-type marking in the size description. That points most buyers toward tubeless fitments, provided the wheels themselves are suitable for tubeless use and are in sound condition.

Wheel condition still matters on a collector car from this era. If the wheel has corrosion, pitting, or prior repairs, a tubeless tire may not seal as intended even when the size itself is tubeless-oriented. A careful inspection of the wheel, valve stem area, and bead seats is the right next step before mounting tires on a 1979 Chrysler that has been sitting or has an unknown wheel history.

All six 1979 Chrysler tire sizes for this year use a 15-inch wheel diameter, so they share the same basic rim diameter. That means a Cordoba, LeBaron, New Yorker, or Newport owner is not sorting between 14-inch and 15-inch fitments here. Rim width is the second part of the equation, and the acceptable width range depends on the exact tire size and, in some cases, the specific product.

A 15-inch wheel on a 1979 Chrysler is only the first checkpoint, not the whole answer. Before moving from one model’s size family to another, verify that the wheel width matches the tire’s approved range and that body, steering, and suspension clearances remain correct. Shared diameter makes comparison easier, but the original wheel should still be evaluated size by size rather than treated as universally interchangeable.

A stored 1979 Chrysler should be kept out of direct sunlight, away from ozone-producing equipment such as electric motors and compressors, and off damp ground whenever possible. Maintaining clean, dry tires and correct inflation helps the casing hold its shape during long periods of rest. Because every fitment here is radial, the car will generally tolerate storage better than an earlier bias-ply car, but long static periods can still create temporary flat-spotting and age-related sidewall cracking.

If the car will sit for months, move it periodically or support it in a way that reduces constant load on one contact patch. A breathable indoor cover and a stable environment do more for tire life than frequent cosmetic dressing. Collector cars often age out their tires long before they wear out, so storage conditions have a direct effect on how fresh the rubber stays over time.

Tires on a 1979 Chrysler should be judged more by age than by mileage, because collector cars often accumulate miles slowly. A sensible rule is to begin evaluating closely at around five to seven years of age and to treat ten years as a strong point for replacement consideration regardless of tread depth. The DOT date code on the tire sidewall tells you when the tire was manufactured.

That timeline matters because a low-mileage Chrysler can still have tires that look decent at first glance but have hardened rubber or internal age-related deterioration. Sidewall condition, ride quality, and air retention all become part of the decision as the tire ages. Even if a car is driven only to shows or weekend events, age should carry more weight than tread wear when deciding whether to keep the tires in service.

Tires on a 1979 Chrysler deserve a quick inspection before every drive and a more careful once-over before any extended outing. Check for sidewall cracking, cuts, bulges, uneven tread wear, and any sign that the tire has been run underinflated. On a collector car, it also makes sense to confirm that the tire is holding pressure consistently and that the valve stems remain supple and leak-free.

That routine is especially important because these cars are often driven intermittently rather than daily. Problems can develop quietly while the car sits, and a tire that looked fine weeks ago may not be ready for a highway run today. Make the spare part of the inspection as well, since an aged spare on a 1979 Chrysler may be no more trustworthy than the four tires already on the ground.

The 1979 Chrysler Cordoba belongs to an era when radial tires were firmly established on American personal-luxury cars, and its period fitments reflect that with FR78-15, GR78-15, and HR78-15 radial sizing. Those alphanumeric radial sizes are consistent with late-1970s original-type fitment practice for a Chrysler of this class. The exact size depended on the specific Cordoba application rather than one universal size for every car.

For restoration work, the right approach is to verify the original size on the car’s paperwork, factory literature, or surviving door-jamb and owner information, then match the sidewall style to the look you are aiming for. If the car is being judged, marque specialists and Chrysler club resources are still the best way to confirm market- and trim-specific details. The important first step is staying within the correct radial size family for the Cordoba.

Correct tire fitment matters on a 1979 Chrysler because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall style right away. On a late-1970s Chrysler, an incorrect size family, the wrong sidewall treatment, or a look that clashes with the model’s original character can stand out even if the tire physically fits the wheel. A formal Newport or New Yorker, for example, presents differently on a whitewall than on a raised white letter tire.

That does not mean every show expects the same standard, but it does mean tire choice should match the goal of the car. A preservation or concours-minded entry usually benefits from a more era-appropriate radial size and sidewall style, while a casual driver can prioritize personal taste within the correct fitment. Event-specific judging rules vary, so club guidance remains the best final checkpoint before a serious show appearance.

Both Coker Classic Star Series and American Classic Radial cover the 195/75R15 size used on certain 1979 Chrysler Newport applications, and both are available in wide whitewall and narrow whitewall forms. Coker Classic’s 195/75R15 carries a 1477-pound load rating at 32 psi, while American Classic versions in the same size carry ratings of 1444 pounds at 35 psi or 1477 pounds at 35 psi depending on the exact tire. Rim-width guidance also differs slightly, with American Classic explicitly covering 5.00- to 7.00-inch rims.

For a Newport owner, the choice is less about changing the car’s fitment and more about selecting the sidewall look and product character that best suits the car. A broad whitewall can emphasize the formal full-size Chrysler style, while a narrower whitewall gives the car a cleaner late-1970s appearance. When comparing the two series, keep wheel width, desired whitewall width, and your preferred inflation/load combination in view.

A sound, correctly sized tire for a 1979 Chrysler can be entirely appropriate for normal highway use, and all current fitments here are radial designs rather than earlier bias-ply constructions. Speed classification varies by product where it is stated: the Michelin 225/70VR15 carries a V rating with a 149 mph ceiling. In real-world use, a late-1970s Chrysler’s own braking, suspension condition, alignment, and overall mechanical state often matter as much as the tire’s nominal capability.

The useful way to think about highway safety is as a complete vehicle question, not just a tire-size question. Fresh rubber, correct inflation, and a chassis in good order make a far bigger difference than chasing the most aggressive-looking sidewall. If the car has been sitting, start with a careful tire inspection and a broader mechanical check before assuming it is ready for an extended high-speed run.

Inflation pressure on a 1979 Chrysler should follow the vehicle manufacturer’s specification for the car and the tire maker’s rating for the tire. Available load-and-pressure figures vary by size: 195/75R15 products appear at 1444 pounds at 35 psi and 1477 pounds at 32 or 35 psi, 205/75R15 products reach 1598 pounds at 35 psi, and 225/70R15 products reach 1753 pounds at 35 psi on several offerings. Those figures describe tire capacity, not a blanket inflation setting for every Chrysler model.

The safest approach is to begin with the car’s factory recommendation and then confirm that your chosen reproduction or modern-style tire is being used within its approved operating range. Do not borrow a pressure figure from one size and assume it belongs on another, even when both fit 15-inch wheels. Matching pressure to the exact tire and exact car is what preserves handling, wear, and load support.

Before a longer drive in a 1979 Chrysler, inspect all four tires and the spare for cracking, cuts, bulges, uneven wear, and proper inflation. Check that the valve stems are sound, the tread is free of embedded damage, and the tires are not so old that age alone has become the main risk. If the car uses a 225/70R15 fitment, also confirm which product is on the car so the speed classification and sidewall style are clear.

That tire check should happen alongside the broader habits any older Chrysler deserves before distance driving: verify brakes, steering response, fluid levels, cooling system condition, and lights. A road test around town can reveal vibration or pull before you commit to a highway trip. Long drives are much more enjoyable when the tire condition and the rest of the car have both been reviewed with the same level of care.
