The 1980 Ford Granada came from a period when domestic midsize sedans were expected to balance comfort, formal styling, and everyday practicality. Buyers remember the Granada for its traditional American look and its role as a sensible personal or family car at the turn of the decade. Tire fitment on the 1980 Ford Granada centers on 14-inch vintage alphanumeric radial sizes, with DR78-14, ER78-14, and FR78-14 appearing across the model range. That makes the real choice less about old bias-ply versus radial construction and more about confirming the exact sub-model and selecting the proper radial size for appearance, stance, and normal road use.
Which Tire Size Is Right for The 1980 Ford Granada
Three primary tire sizes apply to the 1980 Ford Granada, and the difference comes down to sub-model rather than a change in construction or rim diameter. All three are radial tires built for 14-inch wheels, so the first step is confirming whether the car is a Base, ESS, or Ghia and then verifying which 14-inch wheel setup is actually on the vehicle before choosing among the available sizes.
DR78-14 is a vintage alphanumeric radial size in which the letter group identifies the tire's size class, the R denotes radial construction, and the 14 refers to a 14-inch rim. On a 1980 Ford Granada, this size is part of the Base-model fitment range and keeps the tire selection in the period-style radial format used on the car. Because it shares the same basic naming convention as the other Granada sizes, the important distinction is not format but exact size class. Choose it only after confirming the car's specific sub-model and wheel setup.
ER78-14 uses the same vintage alphanumeric radial sizing system, with the final 14 again indicating a 14-inch wheel and the R marking it as a radial tire. This size appears across more than one 1980 Ford Granada sub-model, making it a key fitment to verify carefully on Base and Ghia cars. Its role is tied to the vehicle's original-style radial presentation rather than a modern metric conversion. For a restoration-minded owner or a driver keeping the car close to its period look, the main task is matching the size to the exact Granada configuration.
FR78-14 is also an alphanumeric radial, using the same older size-language format common to American cars of this era and a 14-inch rim. On the 1980 Ford Granada, it is the size associated with the ESS and also appears on Ghia applications, so it is not universal across the full model line. That makes sub-model confirmation especially important before moving ahead with a tire purchase. It is the right size to evaluate when the goal is preserving the Granada's period-correct radial sizing convention on the proper configuration.
Sub-model fitment matters on the 1980 Ford Granada because tire sizing is not the same across the full range. Every version uses a 14-inch radial, but the exact alphanumeric size depends on whether the car is a Base, ESS, or Ghia and, in some cases, which wheel and tire setup it carries.

1980 Ford Granada Base
The 1980 Ford Granada Base uses radial tire fitments in DR78-14 or ER78-14, so there is more than one correct size range within this sub-model. Tire selection starts with confirming the actual wheel-and-tire setup on the car, then choosing the radial size that matches that configuration rather than assuming all Base cars use the same width class.
The 1980 Ford Granada ESS uses FR78-14 radial tires, making its fitment more straightforward than the other sub-models. The main decision is not between several primary sizes, but making sure the car still has the correct 14-inch wheel setup and selecting an FR78-14 tire that suits the car's period-style road-going character.
The 1980 Ford Granada Ghia uses ER78-14 or FR78-14 radial tires, so tire choice depends on the exact setup on the car. That makes wheel verification especially important before replacement, particularly on cars that may have had wheels or tires changed over the years while still keeping the original 14-inch rim diameter.
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
Common questions for the 1980 Ford Granada usually center on which of the three radial sizes belongs on a specific sub-model, how the 14-inch rim fitment works, and what to inspect before putting an older Granada back on the road.
Tire Size & Fitment
What tire size fits a 1980 Ford Granada?
The 1980 Ford Granada uses three primary tire sizes: DR78-14, ER78-14, and FR78-14. All three are radial tires in a vintage alphanumeric format, and all are built for 14-inch rims. The exact size depends on the sub-model, with Base, ESS, and Ghia applications not all sharing the same fitment.
The practical first step is identifying the exact Granada sub-model and then checking what wheel-and-tire setup is actually on the car today. A Base can use DR78-14 or ER78-14, the ESS uses FR78-14, and a Ghia can use ER78-14 or FR78-14, so replacement should follow the specific configuration rather than a one-size-fits-all assumption.
What size rim does a 1980 Ford Granada use?
The primary tire sizes used on the 1980 Ford Granada all mount on 14-inch rims. That holds true whether the car uses DR78-14, ER78-14, or FR78-14, so the rim diameter stays consistent across the covered Granada fitments even though the tire size itself can vary by sub-model.
Rim diameter is only one part of the fitment picture, so it still helps to verify the wheel on the car before replacing tires. An older Granada may have had wheels changed over time, and a 14-inch diameter alone does not confirm that every 14-inch tire size is appropriate for the car's present wheel width, clearance, and sub-model application.
Do all 1980 Ford Granada sub-models use the same tire size?
No. The 1980 Ford Granada sub-models do not all use the same primary tire size. Base models use DR78-14 or ER78-14, the ESS uses FR78-14, and Ghia models use ER78-14 or FR78-14. All are radial 14-inch sizes, but the exact size range changes across the model line.
That difference matters because the tire code is not just a label; it represents a specific size class within the same general radial format. Anyone replacing Granada tires should confirm the sub-model first, then compare the wheel currently on the car and the existing tire markings, especially if the vehicle has been restored, modified, or simply re-tired several times over the years.
Choosing the Right Tire
What should I consider when choosing a DR78-14, ER78-14, or FR78-14 tire for a 1980 Ford Granada?
Start with the correct primary size for the exact 1980 Ford Granada sub-model and wheel setup. DR78-14, ER78-14, and FR78-14 are all 14-inch alphanumeric radials, but they are not interchangeable just because they share the same construction type and rim diameter. The right choice begins with matching the car's actual fitment.
After size is confirmed, think about how the car will be used and how closely the tire should reflect the Granada's original-era look. A regularly driven sedan, a lightly restored cruiser, and a more preservation-focused car can all lead to slightly different priorities, but the size code on the tire should still remain the anchor for the decision.
How do I choose between the available 1980 Ford Granada tire sizes if my car has been changed over the years?
Choose the tire size by the car's current verified setup, not by assumption. A 1980 Ford Granada may have left the factory in one of several radial sizes depending on sub-model, and later wheel or tire changes can blur that history. The original fitment range is DR78-14, ER78-14, or FR78-14, depending on configuration.
The best approach is to confirm the sub-model, read the size currently mounted, and measure the wheel diameter before selecting a replacement. That process is especially important on Base and Ghia cars, where more than one primary size can apply. A careful check avoids buying a period-looking tire that matches the era but not the actual Granada setup.
How do I choose between the available radial sizes for a 1980 Ford Granada sub-model?
The choice depends on which sub-model you have and whether that sub-model allows more than one primary size. On the 1980 Ford Granada, the ESS is straightforward with FR78-14, while Base and Ghia models can use more than one alphanumeric radial size. That means the exact car must be verified before replacement.
Once the correct size is narrowed down, compare the tire to the wheel already on the vehicle and the way the car is meant to be used. For a road-driven Granada, consistency in size and construction is usually more important than experimenting within the 14-inch range, because the fitment differences are tied to the car's intended configuration.
Restoration & Appearance
Which tire should I choose for a period-style 1980 Ford Granada?
A period-style 1980 Ford Granada tire starts with the correct alphanumeric radial size for the car: DR78-14, ER78-14, or FR78-14 depending on sub-model and setup. Because the Granada used radial fitments in this vintage sizing format, keeping that format intact preserves the car's late-1970s to 1980-era visual character better than treating every 14-inch radial as equivalent.
For restoration-minded selection, the best path is matching the proper size first and then choosing a tire presentation that suits the car's overall finish and use. If exact originality matters beyond size and construction format, marque references, original sales materials, and vehicle-specific historical documentation are the right next steps before settling on a final appearance choice.
Does correct tire fitment matter for a 1980 Ford Granada restoration?
Yes, correct tire fitment matters on a 1980 Ford Granada restoration because the car's stance and visual balance depend heavily on using the proper alphanumeric radial size. A Granada restored with the wrong size may still wear a 14-inch tire, but it can look out of proportion to the body and trim level it is meant to represent.
Fitment also matters mechanically, since the correct size helps keep the wheel-and-tire package in line with the car's intended configuration. That is particularly important on Base and Ghia models, where more than one primary size appears. Verifying the exact sub-model and wheel setup before installation keeps the restoration grounded in the proper period-style fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 Ford Granada?
Yes, modifications can affect tire fitment on a 1980 Ford Granada even when the car still uses a 14-inch wheel. Changes such as aftermarket wheels, altered wheel width, suspension lowering, replacement springs, or brake and hub changes can influence how a DR78-14, ER78-14, or FR78-14 tire sits and clears the car.
A Granada that has been changed from its original setup should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before new tires are installed. Even within the correct 14-inch family, the safest buying approach is matching the tire size to the car's actual current configuration instead of assuming a stock fitment still applies.
What should I inspect before driving a 1980 Ford Granada on new tires?
Before driving a 1980 Ford Granada on new tires, inspect the wheels, lug hardware, valve stems, and overall tire seating on the rim. It also helps to confirm that the chosen DR78-14, ER78-14, or FR78-14 size matches the car's sub-model and wheel setup, since the Granada did not use one universal size across the line.
A short road check should include steering feel, rubbing at full lock, visible sidewall clearance, and stable air pressure after initial use. Collector-era sedans that spend long periods parked also deserve a close look at suspension condition, wheel condition, and alignment-related tire wear, because fresh tires cannot correct underlying chassis issues by themselves.
How should radial tires on a collector 1980 Ford Granada be maintained?
Radial tires on a collector 1980 Ford Granada should be maintained with regular pressure checks, visual inspection, and attention to age-related condition as much as tread depth. Cars that are driven occasionally can develop sidewall cracking, flat spotting, or slow air loss long before the tread appears worn out in a normal modern-driver sense.
Storage conditions matter as well, so the car should be kept away from prolonged heat, direct sunlight, excess moisture, and ozone-producing equipment when possible. Periodic inspection of tread, sidewalls, and wheel condition is especially important before a longer drive, since an older Granada may spend months parked between outings and still look better than it is.
