The 1978 Chrysler LeBaron reflects Chrysler’s late-1970s move toward more formal personal-luxury and family-oriented styling, with a strong emphasis on comfort, road manners, and upscale presentation. Whether kept as a coupe, sedan, or wagon-era survivor, it is a car that benefits from tire choices that suit its period character without losing sight of practical road use. The 1978 Chrysler LeBaron uses an FR78-15 radial tire on a 15-inch rim. That keeps the decision focused less on basic size fitment and more on selecting the right radial within that vintage alphanumeric format. For restoration-minded owners and drivers alike, wheel condition, sidewall appearance, and overall stance all deserve a careful look before replacement.
Which Tire Size Is Right for The 1978 Chrysler LeBaron
The 1978 Chrysler LeBaron uses one primary tire size: FR78-15, and it is a radial fitment for a 15-inch rim. That same size carries across the covered LeBaron sub-models, so the main decision is not which primary size fits, but which FR78-15 tire best matches your goals for appearance, road use, and wheel compatibility.
FR78-15 is a vintage alphanumeric radial size in which the letter-based designation identifies the tire’s size class, the R marks radial construction, the 78 indicates its profile family, and the 15 refers to the wheel diameter in inches. On the 1978 Chrysler LeBaron, that radial construction fits the car’s late-1970s character and keeps the vehicle in the sizing language common to the era. Buyers researching this size should pay close attention to the tire’s overall presentation and wheel compatibility rather than trying to translate the car into an unrelated modern size. It is the right starting point for maintaining proper fitment and period-style proportions.
Tire fitment is straightforward across the covered 1978 Chrysler LeBaron sub-models, because each one uses the same FR78-15 radial size. Checking the sub-model still helps confirm that the car remains on its intended wheel setup before selecting a replacement tire.

1978 Chrysler LeBaron Base & Medallion
The 1978 Chrysler LeBaron Base & Medallion uses the FR78-15 radial tire size. That keeps selection centered on finding the right 15-inch radial in the proper vintage format while also confirming the car has not been altered with different wheels over the years.
The 1978 Chrysler LeBaron Wagon also uses the FR78-15 radial tire size. For wagon owners, that means the same basic fitment path applies, with attention shifting toward tire style, road-use needs, and verifying wheel condition before mounting new tires.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
These 1978 Chrysler LeBaron tire FAQs focus on FR78-15 fitment, 15-inch rim compatibility, radial construction, period-style tire selection, and the practical checks that matter before putting a collector-era Chrysler back on the road.
Tire Size & Fitment
What tire size fits a 1978 Chrysler LeBaron?
The 1978 Chrysler LeBaron uses FR78-15 tires. This is a vintage alphanumeric radial size, and it is the primary fitment used across the covered LeBaron configurations, including Base & Medallion models and the Wagon.
That makes FR78-15 the correct starting point when replacing tires on this exact vehicle. The next step is confirming that the car still has its 15-inch wheel setup and has not been changed to aftermarket wheels or a different rim diameter, since many older cars have been altered over time.
What size rim does a 1978 Chrysler LeBaron use?
The 1978 Chrysler LeBaron uses a 15-inch rim with its FR78-15 tire size. The final number in the size code matches the wheel diameter, so the tire is intended for a 15-inch wheel rather than a smaller or larger rim.
Rim diameter should be confirmed at the wheel before purchasing replacement tires, especially on collector vehicles that may have seen wheel swaps during their life. Diameter is only part of the picture, though, so wheel width and overall tire clearance should also be checked before mounting a new set.
Do all 1978 Chrysler LeBaron sub-models use the same tire size?
Yes. The covered 1978 Chrysler LeBaron sub-models use the same FR78-15 radial tire size, including the Base & Medallion group and the Wagon. That means the core fitment does not change from one of these LeBaron versions to another.
Even with shared size fitment, it is still smart to inspect the actual wheels on the car before choosing tires. A LeBaron that has been stored for years, restored, or modified may no longer be wearing its original-style wheel setup, and that can affect tire selection even when the factory-era size remains FR78-15.
Choosing the Right Tire
What should I consider when choosing a FR78-15 tire for a 1978 Chrysler LeBaron?
Start with the basics: the 1978 Chrysler LeBaron uses FR78-15 in a radial construction on a 15-inch wheel. That makes the first priority staying with the correct size and construction format rather than substituting a tire simply because it looks close in diameter or width.
After that, think about how the car will be used and presented. A road-driven LeBaron, a preservation car, and a restoration-oriented car may all call for slightly different priorities in tread style or sidewall appearance, and the actual wheel dimensions on the vehicle should be checked before making the final choice.
How do I choose between the available FR78-15 tires for a 1978 Chrysler LeBaron?
The best way to compare FR78-15 tires for a 1978 Chrysler LeBaron is to begin with fitment and presentation. Since the size itself stays the same, the decision usually comes down to which tire best suits the car’s intended look, level of originality-inspired appearance, and expected driving use.
It helps to compare construction details, wheel compatibility, and the visual character of the tire on the car. A LeBaron with formal late-1970s styling can look quite different depending on sidewall treatment and tread design, so matching the tire’s appearance to the vehicle’s overall theme is just as important as matching the size.
What rim-width specifications should I compare when choosing 1978 Chrysler LeBaron tires?
Rim-width compatibility matters any time a 1978 Chrysler LeBaron is being fitted with new FR78-15 tires. Even when the wheel diameter is correct at 15 inches, the tire still needs to match the actual wheel width so the mounted shape and road behavior stay within the tire’s intended range.
That is especially important on older cars that may have replacement wheels or refinished factory-style rims. Measuring the wheel before purchase helps avoid a tire that looks pinched or stretched, and it also reduces the risk of clearance problems at the suspension, steering components, or outer body lines.
Restoration & Appearance
Which tire should I choose for a period-style 1978 Chrysler LeBaron?
A period-style 1978 Chrysler LeBaron should begin with the proper FR78-15 radial size on a 15-inch wheel. Using the correct vintage alphanumeric radial format helps preserve the car’s late-1970s proportions and keeps the overall presentation in step with the way a LeBaron of this era was typically equipped.
From there, the best choice depends on how original-looking or driver-focused the car is meant to be. Buyers concerned with exact restoration details should compare sidewall styling and overall visual character against marque references, old photos, or restoration documentation rather than assuming any tire sold in FR78-15 matches every factory-delivered appearance.
Does correct tire fitment matter for a 1978 Chrysler LeBaron restoration?
Yes, correct tire fitment matters a great deal on a 1978 Chrysler LeBaron restoration. The right FR78-15 size helps maintain the car’s intended stance, wheel-to-body relationship, and period presentation, all of which have a noticeable effect on how a restored LeBaron looks when viewed from the side.
Fitment also affects more than appearance. A tire that departs too far from the proper sizing format can create unwanted issues with wheel compatibility or visual balance, so restoration-minded owners should confirm the existing wheel setup carefully before replacement and avoid treating near-match modern sizes as automatic substitutes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1978 Chrysler LeBaron?
Yes, modifications can affect tire fitment on a 1978 Chrysler LeBaron even when the intended tire size is still FR78-15. Changes such as aftermarket wheels, altered wheel width, different offset, suspension work, or body modifications can all influence how a tire sits and clears the car.
A LeBaron that has been lowered, raised, or converted to non-original wheels should be inspected more carefully before ordering replacement tires. Checking steering clearance, fender space, and the actual wheel dimensions on the vehicle helps confirm that the chosen tire suits the car as it sits today, not just as it left the era.
What should I inspect before driving a 1978 Chrysler LeBaron on new tires?
Before driving a 1978 Chrysler LeBaron on new tires, inspect the wheels, valve stems, lug hardware, and general condition of the suspension and steering components. Tire pressure should be set correctly, and the mounted tires should be checked for proper seating and adequate clearance at full steering travel.
Collector-era cars often spend long periods parked, so a broader safety check is worthwhile before regular road use. Look over brake condition, signs of fluid leaks, unusual ride height, and any evidence of rubbing from earlier tire setups, since those issues can affect how a fresh set of FR78-15 tires performs on the car.
How should FR78-15 tires on a collector 1978 Chrysler LeBaron be maintained?
FR78-15 tires on a collector 1978 Chrysler LeBaron should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Even a car that is driven sparingly can develop sidewall cracking, flat spotting, tread hardening, or slow air loss if the tires sit for long periods.
Storage conditions matter almost as much as mileage on a low-use Chrysler. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires, and occasional inspections of tread wear and sidewall condition make it easier to catch developing problems before a longer drive.
