The 1977 Lincoln Continental came from an era when American luxury cars emphasized size, isolation, and formal styling, and Lincoln offered that theme across the Continental line with distinctly different wheel-and-tire setups. Tire selection here starts with identifying whether the car uses JR78-15, LR78-15, or the smaller FR78-14 size, all in radial construction. For buyers working with a Base model or Mark V, LR78-15 also opens the door to a period-style bias-look radial with a narrow whitewall presentation. The right choice depends on confirming the exact sub-model, wheel diameter, and whether the goal is restoration-oriented appearance or road-ready replacement.
Which Tire Size Is Right for The 1977 Lincoln Continental
The 1977 Lincoln Continental uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Base and Mark V models use 15-inch radial sizes, while the Versailles uses a 14-inch radial size, so the first step is confirming both the sub-model and the actual wheel currently on the car before choosing a tire.
JR78-15 is a vintage alphanumeric radial size. In this format, the letter-and-number combination identifies the tire's size class and profile family, while the final 15 refers to a 15-inch rim. On a 1977 Lincoln Continental, this size belongs to specific 15-inch-wheel applications rather than the full model range. It suits owners who want to stay with the original radial sizing convention used on these cars and should be selected only after confirming the exact sub-model and wheel diameter.
LR78-15 is also a vintage alphanumeric radial size, with the final 15 indicating a 15-inch rim and the leading designation identifying a larger size class within this older system. For the 1977 Lincoln Continental, it is used on certain 15-inch applications in the Base and Mark V range. Available choices include a Firestone Steel Belted 721 in the Wide Oval Radial series with a narrow whitewall and a bias-look radial construction. This size is worth considering when preserving a traditional late-1970s luxury-car appearance matters as much as correct fitment.
FR78-14 is a vintage alphanumeric radial size designed for a 14-inch rim. The FR designation reflects an older radial sizing system in which the letter and series identify the tire's general width and profile family rather than a modern metric measurement. On the 1977 Lincoln Continental, this size is associated with the Versailles and should not be confused with the 15-inch sizes used elsewhere in the line. Buyers should treat wheel diameter confirmation as essential before moving forward, especially on cars that may have seen wheel changes over time.
Sub-model fitment matters on the 1977 Lincoln Continental because the lineup does not use one universal tire size. Base and Mark V models share 15-inch radial sizing, while the Versailles moves to a 14-inch setup, making exact model identification an important first step.

1977 Lincoln Continental Base
The 1977 Lincoln Continental Base uses 15-inch radial tire sizing, with JR78-15 and LR78-15 associated with this sub-model. That makes wheel confirmation especially important, and LR78-15 buyers may also want to compare the available period-style narrow whitewall bias-look radial option.
The 1977 Lincoln Continental Mark V also uses 15-inch radial tire sizing, sharing JR78-15 and LR78-15 applications. Tire selection centers on confirming which of those two sizes belongs on the specific car and whether the goal is traditional appearance, radial construction continuity, or both.
The 1977 Lincoln Continental Versailles uses FR78-14, separating it from the 15-inch fitments found on other Continental sub-models. That difference makes the wheel diameter check especially important before purchase, particularly on cars that may no longer wear their original wheel-and-tire combination.
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.

Common 1977 Lincoln Continental tire questions usually come down to sub-model fitment, 14-inch versus 15-inch wheels, vintage alphanumeric radial sizing, and how to choose the right appearance and construction for the way the car is used.
Tire Size & Fitment
What tire size fits a 1977 Lincoln Continental?
A 1977 Lincoln Continental can use JR78-15, LR78-15, or FR78-14, depending on the exact sub-model. Base and Mark V models use the 15-inch JR78-15 and LR78-15 radial sizes, while the Versailles uses FR78-14, also in radial construction.
The practical issue is that this Continental line does not share one universal wheel-and-tire package. Before choosing a tire, confirm the sub-model and then verify the wheel diameter currently on the car, especially if it has changed hands, been restored, or received aftermarket wheels at some point.
What size rim does a 1977 Lincoln Continental use?
The 1977 Lincoln Continental uses either a 15-inch or 14-inch rim, depending on the application. JR78-15 and LR78-15 are built for 15-inch rims, while FR78-14 is built for a 14-inch rim.
Rim diameter is the first fitment check because a 14-inch tire and a 15-inch tire are not interchangeable. A quick visual assumption is not enough on an older luxury car, since wheel swaps are common and a Continental may no longer be wearing the same diameter it left the era with.
Do all 1977 Lincoln Continental sub-models use the same tire size?
No. The 1977 Lincoln Continental Base and Mark V use JR78-15 and LR78-15, while the Versailles uses FR78-14. All three are radial sizes, but they are not the same size and they do not use the same rim diameter.
That distinction matters because selecting by year and make alone can lead to the wrong tire. Owners should confirm whether the car is a Base, Mark V, or Versailles first, then match the tire to the wheel diameter already on the vehicle before comparing sidewall style or brand options.
Choosing the Right Tire
What should I consider when choosing a LR78-15 tire for a 1977 Lincoln Continental?
Start with the correct size, construction, and wheel compatibility. LR78-15 is a vintage alphanumeric radial size for a 15-inch rim, and one available option uses bias-look radial construction with a narrow whitewall in the Firestone Wide Oval Radial series.
Selection usually comes down to how the car will be presented and driven. A traditional sidewall treatment can better suit a restoration-oriented look, while the rim-width range should still be checked against the actual wheel on the car so appearance and fitment both stay in line.
What sidewall styles are available for 1977 Lincoln Continental tires?
Among the available 1977 Lincoln Continental product choices, LR78-15 is offered with a narrow whitewall. That gives the car a more formal late-1970s luxury presentation than a plain blackwall would, while still staying within the correct size family for certain 15-inch applications.
Sidewall style affects appearance more than fitment, but it can strongly influence the finished look of the car. Buyers should first confirm the right size and wheel diameter, then choose the sidewall treatment that best matches the car's trim level, restoration direction, and overall visual character.
What brands offer tires for the 1977 Lincoln Continental?
Firestone is available for the 1977 Lincoln Continental in LR78-15 through the Steel Belted 721 line. That tire falls within the Wide Oval Radial series and combines radial construction with a bias-look profile for a more traditional visual effect.
Brand choice matters only after the fitment basics are settled. Once the exact sub-model, tire size, and rim diameter are confirmed, the useful comparison points become construction style, sidewall treatment, rim-width compatibility, and whether the tire's overall appearance matches the character of the car.
Restoration & Appearance
Which tire should I choose for a period-style 1977 Lincoln Continental?
A period-style choice starts with using the correct size for the exact sub-model, since the 1977 Lincoln Continental spans JR78-15, LR78-15, and FR78-14. For certain 15-inch applications, LR78-15 is available as a bias-look radial, which helps preserve a traditional late-1970s visual character.
Appearance should be balanced with fitment accuracy. Wheel diameter, actual wheel width, and the car's intended use still matter, and buyers pursuing strict originality should compare the tire's look against marque references or restoration records rather than assuming every period-style option matches every Continental exactly.
How does tire construction affect the appearance of a restored 1977 Lincoln Continental?
On a restored 1977 Lincoln Continental, construction can change the look as much as the ride. The primary fitments here are radial sizes, and a bias-look radial in LR78-15 offers a way to keep radial construction while presenting a more traditional tire profile.
That distinction matters because two tires in the same size family can give the car a different visual stance. Owners concerned with show presentation usually focus on the overall sidewall shape and whitewall treatment, while road-use buyers may place equal emphasis on correct wheel match and dependable radial construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1977 Lincoln Continental?
Yes. Modifications such as aftermarket wheels, suspension changes, altered ride height, or brake conversions can affect tire fitment on a 1977 Lincoln Continental even when the chosen size is otherwise correct for the model or sub-model.
Older luxury cars are especially worth checking carefully because wheel swaps between 14-inch and 15-inch setups are not unusual. Clearance at the fender, steering range, and the wheel's actual width should all be confirmed on the car itself before mounting tires, particularly when returning a modified vehicle to stock-style sizing.
What should I inspect before driving a 1977 Lincoln Continental on new tires?
Before road use, inspect the wheel condition, lug hardware, valve stems, and overall suspension health, then confirm that the new tires match the vehicle's actual wheel diameter and size requirement. Tire pressure should also be set correctly and rechecked after the first miles of driving.
A 1977 Continental is a heavy car, so any vibration, pull, rubbing, or air loss should be addressed immediately. It is also wise to look for worn steering parts, cracked bushings, or uneven old-tire wear patterns, since those clues can point to alignment or clearance issues that new tires will not solve.
How should tires on a collector 1977 Lincoln Continental be maintained?
Collector-car tires should be maintained with regular pressure checks, visual inspections, and occasional movement of the car so one area of the tread is not loaded for long periods. Sidewalls and tread should be watched for cracking, bulges, cuts, and any signs of slow air loss.
Storage conditions matter just as much as mileage on a low-use Continental. Keeping the car away from prolonged sunlight, moisture, excessive heat, and ozone sources helps preserve the tires, and a careful inspection before each longer drive is a smart habit even when the tread still looks fresh.
