The 1975 Ford Pinto came from an era when compact American cars were expected to be economical, easy to live with, and modern enough to reflect changing driving habits of the 1970s. Whether kept as a preserved survivor or refreshed for regular local use, a Pinto from this period benefits from getting its tire fitment right. The 1975 Ford Pinto uses 13-inch radial tire sizes in vintage alphanumeric form, with BR70-13 and BR78-13 both associated with this model. That leaves room to sort out which profile matches the car, the wheel setup, and the look you want. For a restoration-minded owner, the key is balancing authentic-era sizing with practical fitment confirmation before the car goes back on the road.
Which Tire Size Is Right for The 1975 Ford Pinto
The 1975 Ford Pinto uses two primary tire sizes, and both are radial tires built for a 13-inch rim. Because BR70-13 and BR78-13 appear across the covered Pinto sub-models, the first step is confirming which size is actually on the car or intended for its wheel setup before narrowing the choice to tire style and overall profile.
BR70-13 is a vintage alphanumeric radial size. In this format, the letters identify the size class, the R indicates radial construction, the 70 points to the profile family, and the 13 designates the wheel diameter in inches. On a 1975 Ford Pinto, this size suits owners who want to stay with an era-appropriate radial format while confirming the car's exact tire profile. The practical decision is making sure the wheel and stance match this lower-profile alphanumeric radial rather than assuming every 13-inch Pinto setup used the same tire proportions.
BR78-13 is also a vintage alphanumeric radial, but its profile family differs from BR70-13 even though both mount on 13-inch wheels. The lettered sizing reflects an older radial convention common to the period, which makes it useful for owners trying to preserve a 1970s tire presentation without moving into a modern metric size. For a 1975 Ford Pinto, this size is worth evaluating when the car's current wheel-and-tire combination points to the taller 78-series style. Confirming the actual wheel setup and available clearance remains important before settling on this profile.
Tire fitment is fairly straightforward across the covered 1975 Ford Pinto sub-models because both the 2 & 3 Dr. and Wagon are associated with the same two radial sizes. The main task is confirming which of those two 13-inch profiles belongs on the specific car in front of you.

1975 Ford Pinto 2 & 3 Dr.
The 1975 Ford Pinto 2 & 3 Dr. uses the same pair of 13-inch radial fitments seen elsewhere in the model range, so the focus is not body style differences but choosing between the two available alphanumeric radial profiles. That makes wheel confirmation and present-car fitment more important than trim-based assumptions.
The 1975 Ford Pinto Wagon is also associated with the same two 13-inch radial tire sizes, keeping fitment consistent with the other covered Pinto configuration. Tire selection comes down to identifying which profile matches the wagon's wheels and intended appearance rather than searching for a wagon-only size.
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 1975 Ford Pinto tire questions usually come down to the difference between BR70-13 and BR78-13, 13-inch rim fitment, period-style radial sizing, and what to inspect before putting a collector-era compact back into regular road use.
Tire Size & Fitment
What tire size fits a 1975 Ford Pinto?
A 1975 Ford Pinto uses one of two primary tire sizes: BR70-13 or BR78-13. Both are radial tires in vintage alphanumeric sizing, and both are designed for a 13-inch rim. The covered Pinto sub-models share these same two size options rather than using completely different wheel diameters.
The important next step is determining which of those two profiles belongs on the specific car. A 13-inch wheel alone does not settle the question, because BR70-13 and BR78-13 are different radial size formats within the same rim diameter. Checking the current wheel-and-tire setup, sidewall markings, and available clearance helps narrow the choice.
What size rim does a 1975 Ford Pinto use?
The primary tire sizes for the 1975 Ford Pinto both mount on a 13-inch rim. That applies to BR70-13 and BR78-13, so the wheel diameter stays the same even though the tire size itself can vary. In practical terms, the Pinto's tire decision is about profile selection rather than choosing between different rim diameters.
Wheel diameter is only part of the fitment picture, especially on an older car that may have been changed over time. Measuring the actual wheel, confirming its width, and comparing it to the tire already on the car can prevent ordering the right diameter in the wrong profile. That check is especially useful if the Pinto has seen replacement wheels at any point.
Do all 1975 Ford Pinto sub-models use the same tire size?
The covered 1975 Ford Pinto sub-models share the same two tire sizes, BR70-13 and BR78-13. That includes the 2 & 3 Dr. and the Wagon, and both sizes are radial constructions on 13-inch rims. So sub-model fitment is consistent in size range, even though more than one tire profile is still in play.
Shared fitment across sub-models does not mean every individual Pinto should automatically use either size without a closer look. The car may still need one profile rather than the other depending on its present wheels, previous tire replacement history, and how closely the owner wants to match an era-appropriate setup. Verifying the exact tire already fitted is the smartest place to start.
Choosing the Right Tire
What should I consider when choosing a BR70-13 or BR78-13 tire for a 1975 Ford Pinto?
Start with the exact primary size the car uses, because the 1975 Ford Pinto can take either BR70-13 or BR78-13, and those are not the same profile. Both are vintage alphanumeric radial sizes for a 13-inch rim, so the choice begins with correct fitment rather than simply selecting any 13-inch tire that looks close.
After the size is settled, compare the wheel setup, the car's stance, and the kind of appearance you want from a 1970s compact. A survivor-style Pinto may call for staying close to its existing radial profile, while a modified car may need extra clearance checks. Tire age, overall condition, and how the car will actually be driven also matter.
How do I choose between the available BR70-13 and BR78-13 tires for a 1975 Ford Pinto?
Choosing between BR70-13 and BR78-13 starts with identifying which size belongs on the car, not with personal preference alone. Both are period-style radial fitments for the 1975 Ford Pinto, but they represent different profile families within the same 13-inch rim diameter. That means one size may suit the wheel-and-car setup better than the other.
A careful comparison should include the sidewall size currently on the car, wheel measurements, and visual clearance at the fender and steering range. Owners also tend to think about how original-looking they want the Pinto to remain. Even when two sizes appear close at a glance, profile differences are enough to justify a proper fitment check first.
What tire series are available for the 1975 Ford Pinto?
The main tire-series question for a 1975 Ford Pinto is less about broad variety and more about staying within the correct vintage radial sizing format. BR70-13 and BR78-13 are both alphanumeric radial sizes associated with the car, so the series-style decision centers on selecting the right profile family before moving on to any finer product differences.
That matters because a collector-era compact often looks noticeably different when the tire profile changes, even if the wheel diameter stays at 13 inches. Owners comparing tires for a Pinto should focus on the exact size code, the radial construction, and how the tire suits the car's intended appearance and use. Fitment accuracy comes before cosmetic preference.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Ford Pinto?
For a period-style 1975 Ford Pinto, the best starting point is one of the two original-format radial sizes associated with the car: BR70-13 or BR78-13. Both use vintage alphanumeric radial sizing on a 13-inch rim, which makes them more visually in step with a 1970s compact than a generic modern substitute in a different sizing language.
The right choice depends on which profile belongs on the specific Pinto and how closely the owner wants to preserve its era-appropriate stance. A careful restoration should compare the existing tire markings, wheel dimensions, and any historical references tied to that exact car. That approach helps keep the result credible without assuming one size suits every restored Pinto.
Does correct tire fitment matter for a 1975 Ford Pinto restoration?
Correct tire fitment matters on a 1975 Ford Pinto restoration because the tire's size format, profile, and rim diameter all influence how the car sits and how authentic the finished presentation feels. On this Pinto, the relevant primary sizes are BR70-13 and BR78-13, both in vintage alphanumeric radial form for 13-inch wheels.
Restoration-minded owners usually care about more than simple roadworthiness. Tire choice affects wheelwell fill, sidewall character, and whether the car reads as properly 1970s rather than generically updated. Even when the goal is not concours judging, matching the tire to the car's intended look and confirming wheel compatibility can make the finished restoration feel much more coherent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Ford Pinto?
Yes. Modifications can change tire fitment on a 1975 Ford Pinto even when the car still uses a 13-inch wheel. Lowering, altered springs, aftermarket wheels, wheel-width changes, or bodywork around the fenders can all affect whether BR70-13 or BR78-13 is the better match. Small compact cars tend to show those differences more quickly than larger platforms.
A modified Pinto should be checked at full steering range and through normal suspension travel before settling on a tire size. Wheel width and offset deserve special attention because they can shift the tire inward or outward even with the same rim diameter. That inspection is more reliable than assuming stock-size markings still tell the whole story.
What should I inspect before driving a 1975 Ford Pinto on new tires?
Before driving a 1975 Ford Pinto on new tires, inspect the wheels, valve stems, lug hardware, and the basic condition of the suspension and steering components. Confirm that the tire size matches the intended fitment, that each tire is seated properly on the 13-inch rim, and that there is no obvious interference at the fenders or inner wheel area.
A short, careful road test should follow the visual inspection. Pay attention to rubbing during turns, unusual vibration, wandering, or air loss after the first drive. On a collector-era Pinto that may have spent time parked, it also makes sense to recheck tire pressure and wheel fastener torque soon after installation. Early inspection helps catch setup issues before they become bigger problems.
How should BR70-13 or BR78-13 tires on a collector 1975 Ford Pinto be maintained?
Collector-car tire care for a 1975 Ford Pinto starts with regular pressure checks, visual inspections, and paying attention to age as well as tread depth. BR70-13 and BR78-13 tires may spend long periods carrying little mileage, so condition matters more than odometer use alone. Cracking, flat spotting, bulges, cuts, or recurring air loss all deserve prompt attention.
Storage habits make a real difference on a lightly used Pinto. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives. It also helps to move the car periodically or adjust storage practice to avoid long-term stress in one contact patch. Inspection before each outing is a smart habit for any infrequently driven classic.
