The 1979 Chrysler Cordoba reflects the late-1970s personal luxury coupe formula, combining formal styling, a quiet cruising character, and the kind of road presence that made these Mopar two-doors stand out in their era. Tire choice on this exact car matters because the 1979 Chrysler Cordoba uses 15-inch radial fitments in vintage alphanumeric sizes, with FR78-15, GR78-15, and HR78-15 appearing across the covered configurations. That means the real decision is not only size, but also matching the correct fitment to the engine-equipped sub-model. For a restoration-minded owner or a driver preparing the car for regular road use, wheel confirmation and exact size selection should come before anything else.
Which Tire Size Is Right for The 1979 Chrysler Cordoba
The 1979 Chrysler Cordoba uses three primary tire sizes, and all of them are 15-inch radial fitments in vintage alphanumeric form. The key step is identifying the exact sub-model, because tire size varies by engine-equipped configuration even though the rim diameter remains the same. Once that is confirmed, the decision becomes choosing the tire that matches the car's intended look, driving use, and wheel setup.
FR78-15 is a vintage alphanumeric radial size. In this format, the letter group identifies the tire's size class, the R indicates radial construction, the 78 refers to the profile family, and 15 is the rim diameter in inches. On the 1979 Chrysler Cordoba, this size is part of the model's factory-era radial fitment story rather than a later conversion choice. It is the right size to evaluate when your Cordoba falls into the configuration that uses FR78-15, and the wheel itself should still be confirmed before selecting a tire.
GR78-15 is also a vintage alphanumeric radial size, using the same basic format of size-class letters, a radial construction marker, a 78-series profile family, and a 15-inch rim diameter. For the 1979 Chrysler Cordoba, this size sits in the middle of the covered fitment range and appears across more than one sub-model configuration. That makes it especially important to verify the car's exact setup rather than assume one Cordoba tire size fits all. It is the size to focus on when your particular car calls for GR78-15 on its 15-inch wheels.
HR78-15 follows the same vintage alphanumeric radial sizing system, with the H size class, radial construction, 78-series profile family, and 15-inch rim diameter all built into the code. On a 1979 Chrysler Cordoba, this size is tied to specific covered configurations rather than the full model line. Buyers considering HR78-15 should treat it as a fitment-specific choice, not simply the largest option in the group. Confirming the sub-model and checking the actual wheel on the car are the important next steps before settling on this size.
Tire fitment on the 1979 Chrysler Cordoba varies by engine-equipped sub-model, even though all covered versions use 15-inch radial tires. Checking the exact sub-model matters because the correct tire size overlaps in some cases but does not remain identical across the full Cordoba range.

Frequently Asked Questions
These FAQs focus on the 1979 Chrysler Cordoba's exact tire sizes, 15-inch rim fitment, sub-model differences, and the practical checks that matter before putting a restored or road-driven car back on its tires.
Tire Size & Fitment
What tire size fits a 1979 Chrysler Cordoba?
A 1979 Chrysler Cordoba uses one of three vintage alphanumeric radial sizes: FR78-15, GR78-15, or HR78-15. The correct size depends on the car's engine-equipped sub-model, with the 318-equipped Cordoba using FR78-15 or GR78-15 and the 360-equipped Cordoba using GR78-15 or HR78-15.
The practical takeaway is that a Cordoba owner should confirm more than just the model year before ordering tires. Since GR78-15 appears across both covered sub-models, it is especially important to verify the exact configuration and inspect the wheels currently on the car, particularly if it has been modified, restored, or changed from its earlier setup.
What size rim does a 1979 Chrysler Cordoba use?
The covered tire fitments for the 1979 Chrysler Cordoba all use a 15-inch rim diameter. FR78-15, GR78-15, and HR78-15 are all built around that same 15-inch wheel size, so the rim diameter remains consistent even though the tire size itself can vary by sub-model.
That consistency helps narrow the search, but it does not remove the need to confirm the actual wheel on the car. A 15-inch diameter is only one part of fitment, and wheel width, any aftermarket wheel changes, and available clearance around the suspension and body still deserve a close look before mounting replacement tires.
Why does the 1979 Chrysler Cordoba have more than one tire size?
The 1979 Chrysler Cordoba has more than one tire size because fitment varies across the covered engine-equipped sub-models. The 318-equipped Cordoba uses FR78-15 or GR78-15, while the 360-equipped Cordoba uses GR78-15 or HR78-15, so the full model line does not rely on a single universal tire size.
For the buyer, that means the first job is identifying exactly which Cordoba configuration is sitting in the garage. It is also wise to confirm what wheels are actually on the car today, since decades of repairs, wheel swaps, and restoration choices can leave a surviving vehicle wearing a different setup than expected.
Choosing the Right Tire
What should I consider when choosing a GR78-15 tire for a 1979 Chrysler Cordoba?
Start with fitment accuracy. GR78-15 is one of the correct radial sizes for the 1979 Chrysler Cordoba, but it applies only to the covered configurations that use it, not automatically to every Cordoba. Matching the tire size to the exact sub-model and confirming the car still has the proper 15-inch wheels should come before any other decision.
After size is confirmed, the next considerations are how the car will be used and how original-looking you want it to remain. A Cordoba aimed at preservation may call for a more period-style presentation, while a regularly driven car may put more emphasis on consistent condition, wheel compatibility, and making sure the overall setup remains appropriate.
How do I choose between the available FR78-15, GR78-15, and HR78-15 tires for a 1979 Chrysler Cordoba?
The first step is not choosing among the three sizes by preference, but by fitment. FR78-15, GR78-15, and HR78-15 are all correct 15-inch radial sizes for the 1979 Chrysler Cordoba, yet each belongs to specific covered sub-model applications. The car's engine-equipped configuration should determine which size belongs in the final selection.
Once the correct size is established, compare the tire against the car's present wheel and overall condition. A Cordoba that still carries its intended wheel setup is a simpler case, while one with replacement wheels, suspension changes, or unknown history deserves a closer inspection before settling on any of the three listed sizes.
What rim-fitment details should I compare when choosing tires for a 1979 Chrysler Cordoba?
The main confirmed rim detail for the 1979 Chrysler Cordoba is diameter: the covered tire sizes all use a 15-inch rim. That gives a solid starting point, but proper tire selection should also take the actual wheel on the car into account so the chosen size matches the wheel setup instead of just the model-year fitment range.
A careful check should include the wheel's true diameter, its width, and whether the car still wears factory-type wheels or something added later. Cordobas that have seen years of maintenance or style changes can end up with a different wheel package, and that can affect both the tire choice and available clearance.
Restoration & Appearance
Which tire should I choose for a period-style 1979 Chrysler Cordoba?
A period-style 1979 Chrysler Cordoba starts with the correct vintage alphanumeric radial size for the exact sub-model: FR78-15, GR78-15, or HR78-15. Because these are primary radial fitments for the car rather than a later radial conversion from bias-ply, keeping the correct size format is an important part of preserving the Cordoba's late-1970s character.
Appearance-minded buyers should focus first on the proper size and overall presentation rather than chasing a generic larger-or-smaller look. If exact originality is the goal, vehicle-specific historical references, marque-club guidance, and restoration records can help narrow down the right visual treatment once the correct fitment has been established.
Does correct tire fitment matter for a 1979 Chrysler Cordoba restoration?
Correct tire fitment matters because the tire is a major visual and functional part of a restored 1979 Chrysler Cordoba. Using the proper FR78-15, GR78-15, or HR78-15 size for the exact sub-model helps the car keep the proportions and stance associated with its original-era radial fitment.
Restoration work also benefits from checking the wheels already on the vehicle, since long-owned cars are often changed over time. A Cordoba can look complete at a glance yet still carry a wheel or tire package that alters its appearance, so confirming the basics before mounting new tires helps avoid rework later.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1979 Chrysler Cordoba?
Yes, modifications can affect tire fitment on a 1979 Chrysler Cordoba even when the intended size is correct for the sub-model. Aftermarket wheels, altered wheel width, suspension changes, ride-height adjustments, or body repairs can all change how an FR78-15, GR78-15, or HR78-15 tire sits in the wheel opening.
A modified Cordoba deserves a physical inspection before new tires go on. Check the actual wheel dimensions, look at clearance during steering and suspension movement, and make sure the tire does not come too close to fenders or chassis components. That extra step matters more on cars that have passed through several owners.
What should I inspect before driving a 1979 Chrysler Cordoba on new tires?
Before road use, inspect the wheel condition, confirm the 15-inch rim setup, and make sure the selected tire size matches the exact Cordoba sub-model. It is also smart to look over the suspension, steering components, and brake system, since fresh tires can highlight problems that were less obvious with worn or aged rubber.
A road-ready check should also include tire pressure, lug hardware, and visible clearance around the wheel openings. On a collector-era car like the Cordoba, age can affect more than the tires themselves, so a short local test drive and a second inspection afterward can reveal rubbing, settling, or air-loss issues early.
How should tires on a collector 1979 Chrysler Cordoba be maintained?
Tires on a collector 1979 Chrysler Cordoba should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even if the car sees limited mileage, the tires still need attention for cracking, bulges, cuts, uneven wear, and gradual air loss, especially when the car spends long periods parked indoors.
Good collector-car practice includes moving the vehicle periodically, keeping it away from prolonged heat and ozone sources, and checking the tires before each season of driving. Low annual mileage does not prevent tire aging, so condition matters just as much as tread depth when deciding whether the Cordoba is ready for the road.
