The 1977 Ford Pinto belongs to the late-1970s compact era, when small domestic cars balanced economy, practicality, and everyday drivability in a very different market from earlier muscle-car years. Whether preserved as a clean survivor or kept on the road as a well-maintained driver, a Pinto benefits from getting the tire size and profile right for its original character. The 1977 Ford Pinto uses BR70-13 and BR78-13 radial tire sizes on 13-inch rims. That makes the main decision less about switching construction and more about confirming the right size for the car, then choosing a tire that matches the intended stance, appearance, and road use.
Which Tire Size Is Right for The 1977 Ford Pinto
The 1977 Ford Pinto uses two primary tire sizes, both in radial construction on 13-inch rims. Because BR70-13 and BR78-13 can appear on both the 2 & 3 Dr. and Wagon, the important first step is confirming which size is actually on the vehicle or intended for its wheel setup. After that, the choice becomes one of profile, appearance, and overall fitment suitability.
BR70-13 is a vintage alphanumeric radial size. The B identifies the general size class, R indicates radial construction, 70 refers to the profile family, and 13 is the rim diameter in inches. On a 1977 Ford Pinto, this size suits buyers who want to stay with a period-style radial format while keeping the car on the correct 13-inch wheel diameter. It is worth checking the wheel and current tire setup closely, since this size should be chosen to match the car's actual configuration rather than assumed from model name alone.
BR78-13 is also a vintage alphanumeric radial size, using the same 13-inch rim diameter but a different profile family from BR70-13. The B marks the size class, R denotes radial construction, 78 identifies the profile grouping, and 13 is the wheel diameter. For a 1977 Ford Pinto, BR78-13 is part of the original-style radial fitment picture and should be selected only after confirming the vehicle's wheel and existing size. That makes it especially important for owners comparing stance, tire profile, and overall appearance on a survivor or restoration-minded car.
Fitment is fairly straightforward across the covered 1977 Ford Pinto sub-models, since both the 2 & 3 Dr. and Wagon use the same two radial size families. Checking the exact sub-model still helps keep the selection process organized, especially when confirming what is already mounted on the car.

1977 Ford Pinto 2 & 3 Dr.
The 1977 Ford Pinto 2 & 3 Dr. uses the same BR70-13 and BR78-13 radial fitment pattern found elsewhere in the model line. That means the key step is confirming which of those two 13-inch radial sizes matches the car's present wheel and tire setup before choosing a replacement.
The 1977 Ford Pinto Wagon also uses BR70-13 and BR78-13 radial tire sizes on 13-inch rims. For tire selection, that keeps the focus on verifying the actual size used on the vehicle, then choosing the profile and overall presentation that best suits a wagon kept for preservation or regular road use.
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 FAQs focus on the two radial tire sizes used on the 1977 Ford Pinto, along with 13-inch rim fitment, size interpretation, restoration-minded tire choice, and the checks worth making before putting a collector-era compact back on the road.
Tire Size & Fitment
What tire size fits a 1977 Ford Pinto?
A 1977 Ford Pinto uses either BR70-13 or BR78-13, and both are radial tire sizes. Those two sizes appear across the covered Pinto range, including the 2 & 3 Dr. and Wagon, so the model year alone does not narrow the choice to one size.
The practical next step is to confirm which size is actually mounted on the car or intended for its current wheel setup. Since both sizes use a 13-inch rim but represent different profile families, checking the sidewall marking, wheel dimensions, and clearance around the suspension and fenders helps prevent choosing the wrong replacement.
What size rim does a 1977 Ford Pinto use?
The 1977 Ford Pinto uses a 13-inch rim diameter with both BR70-13 and BR78-13 tire sizes. That means the wheel diameter remains consistent even though the car can use more than one primary radial size within that 13-inch fitment range.
Rim diameter is only one part of the fitment picture, so it is still smart to verify the wheel itself before ordering tires. A Pinto that has had wheel changes over the years may no longer be on its original setup, and wheel width or offset changes can affect how either BR70-13 or BR78-13 sits and clears.
Do all 1977 Ford Pinto sub-models use the same tire size?
The covered 1977 Ford Pinto sub-models share the same two tire sizes: BR70-13 and BR78-13. Both the 2 & 3 Dr. and the Wagon use those radial fitments, so there is no separate size split between those two sub-model groups in this application.
Even with that shared fitment pattern, the right replacement still depends on the exact size already on the vehicle or the wheel setup being used. It is a good idea to check the current sidewall marking and inspect wheel condition at the same time, especially on older cars that may have seen tire and wheel changes over decades.
Choosing the Right Tire
What should I consider when choosing a BR70-13 or BR78-13 tire for a 1977 Ford Pinto?
Start by confirming whether the car uses BR70-13 or BR78-13, since both are primary radial fitments for the 1977 Ford Pinto. The key difference is not construction, because both are radial, but selecting the correct profile family for the car's existing wheel and overall setup.
Once the size is confirmed, think about how the Pinto is used and presented. A preservation-minded car may call for a more period-style look, while a regular driver may place more emphasis on general road use and condition. Wheel width, clearance, and the car's current stance should all be checked before settling on either size.
How do I choose between the available BR70-13 and BR78-13 tires for a 1977 Ford Pinto?
Choosing between BR70-13 and BR78-13 begins with fitment, not preference. Both sizes belong to the 1977 Ford Pinto, but they are not interchangeable by assumption simply because they share the same 13-inch rim diameter and radial construction.
A smart approach is to match the replacement tire to the size already on the car unless there is a clear reason to review the setup more closely. If the Pinto has different wheels, suspension changes, or uncertain history, measure the wheels and inspect fender and steering clearance before deciding which of the two radial sizes makes the most sense.
What rim-fitment details should I compare when choosing 1977 Ford Pinto tires?
The first rim-fitment detail is diameter, and the 1977 Ford Pinto uses a 13-inch wheel with both BR70-13 and BR78-13. After that, wheel width and the actual wheel setup on the car matter because the same diameter does not automatically make every tire choice equally suitable.
It also helps to inspect offset, wheel condition, and how much room exists at the fender edge and around steering components. On an older Pinto, previous owners may have changed wheels without leaving much record, so verifying the wheel before replacing tires keeps the choice tied to the vehicle in front of you rather than assumptions.
Restoration & Appearance
Which tire should I choose for a period-style 1977 Ford Pinto?
A period-style starting point for a 1977 Ford Pinto is to stay with one of its original-style radial formats, either BR70-13 or BR78-13, depending on the car's actual setup. Because both sizes are vintage alphanumeric radials, they preserve the look of a late-1970s compact more naturally than a modern-looking size conversion.
The best choice depends on what is already on the car, how the stance looks, and how closely the vehicle is being restored. When exact originality matters, it is worth checking marque literature, build-related references, or other vehicle-specific documentation before making a final appearance-driven decision between the two supported sizes.
Does correct tire fitment matter for a 1977 Ford Pinto restoration?
Yes, correct tire fitment matters on a 1977 Ford Pinto restoration because tire size has a strong effect on stance, wheel-well fill, and the overall look of a finished car. On this Pinto, that means choosing the proper radial size family from BR70-13 or BR78-13 rather than treating any 13-inch tire as close enough.
Fitment also affects how authentic and settled the car appears once it is back on the road. A restoration-minded owner should confirm the wheel setup, read the sidewall on any existing tires, and compare the look of the car carefully before changing size. Small differences in profile can change the visual balance more than expected.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1977 Ford Pinto?
Yes, modifications can affect tire fitment on a 1977 Ford Pinto even when the car still uses a 13-inch wheel. Changes such as aftermarket wheels, altered wheel offset, suspension lowering, spring replacement, or body work can influence whether BR70-13 or BR78-13 is still the most sensible fitment choice.
A modified car should be checked at full steering lock and through normal suspension movement before replacement tires are chosen. It also helps to measure wheel width and inspect for rubbing marks near the fenders or inner wheelhouse. Those checks are especially worthwhile on older compacts that may have seen several rounds of changes over time.
What should I inspect before driving a 1977 Ford Pinto on new tires?
Before driving a 1977 Ford Pinto on new tires, inspect the wheels for damage, confirm the tire size matches the intended fitment, and make sure inflation is set correctly for the tires being used. It is also wise to look over the valve stems, lug hardware, and general wheel condition before the car returns to regular road use.
The car itself deserves equal attention. Check suspension and steering components for looseness, look for any signs of tire-to-body contact, and make sure the alignment is not visibly off. A Pinto that has spent long periods parked can also hide age-related issues, so a careful first road test is better than assuming everything is settled immediately.
How should BR70-13 or BR78-13 tires on a collector 1977 Ford Pinto be maintained?
BR70-13 and BR78-13 tires on a collector 1977 Ford Pinto should be maintained with regular pressure checks, routine visual inspection, and clean storage habits. Even a lightly used car can develop tire issues over time, so sidewall cracking, bulges, cuts, unusual wear, and gradual air loss deserve attention well before the next drive.
Storage conditions matter almost as much as mileage on a low-use Pinto. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps protect the tires, and rolling the vehicle periodically can help avoid long-term flat spotting. Any tire showing age-related deterioration should be evaluated before the car is used at road speed.
