The 1974 Ford Pinto sits squarely in the compact-car era when small domestic cars were expected to be practical, economical, and easy to live with every day. That makes tire selection especially important, because the Pinto’s character depends heavily on choosing the right 13-inch fitment for the exact body style and setup. This model uses 600-13, A78-13, and BR78-13 sizes, with both bias-ply and radial fitments appearing across the range. That creates a meaningful choice between traditional bias-ply sizing and available modern radial equivalents for the bias-ply sizes. For a restoration-minded owner or a driver-focused owner, the first step is matching the right size to the right Pinto sub-model.
Which Tire Size Is Right for The 1974 Ford Pinto
Three primary tire sizes apply to the 1974 Ford Pinto, and they vary by sub-model and construction rather than wheel diameter, since all of them use a 13-inch rim. The key step is identifying whether the car is a 2 & 3 Dr. or a Wagon, then deciding whether the goal is to retain the original-style bias-ply fitment or evaluate an appropriate radial alternative where one exists.
The 600-13 size uses the older numeric bias-ply system, where the leading number refers to a nominal section width of about 6.00 inches and the final number indicates a 13-inch rim. On the 1974 Ford Pinto, this is a traditional bias-ply fitment that suits owners keeping a period-style driving feel and vintage tire appearance. Available 600-13 choices include BFGoodrich Silvertown Classic Bias Ply options with both wide whitewall and narrow whitewall sidewall treatments. It is the size to evaluate when the car is one of the Pinto sub-models that used 600-13 and the goal is an authentic small-car bias-ply presentation.
A78-13 uses the vintage alphanumeric bias-ply system, where the letter identifies the tire’s size class, the 78 indicates its profile family, and the 13 identifies rim diameter. For the 1974 Ford Pinto, this is another primary bias-ply fitment and it differs from 600-13 even though both mount on 13-inch wheels. Buyers looking at A78-13 are usually balancing original-style construction against the option of moving to a radial equivalent in a comparable sizing family. The important step is confirming that the car’s sub-model and wheel setup match A78-13 before choosing within that fitment.
BR78-13 is an alphanumeric radial size, and the presence of the R in the code identifies radial construction rather than bias-ply. On the 1974 Ford Pinto, this size appears as a primary fitment for certain sub-models, making it distinct from the bias-ply 600-13 and A78-13 options. Because it shares the same 13-inch rim diameter, the decision is not simply about wheel size but about using the radial size tied to the correct Pinto configuration. It should be evaluated by owners who want to preserve the Pinto’s radial fitment rather than substitute a different primary size.
Sub-model identification matters on the 1974 Ford Pinto because tire fitment is not the same across the body styles covered here. The 2 & 3 Dr. and the Wagon overlap in some sizing, but they do not use the exact same mix of bias-ply and radial options.

1974 Ford Pinto 2 & 3 Dr.
The 1974 Ford Pinto 2 & 3 Dr. uses bias-ply sizes, with 600-13 and A78-13 both applying to this sub-model. That makes the selection process less about radial fitment and more about confirming which bias-ply size matches the car, then choosing the desired period-style look within that size.
The 1974 Ford Pinto Wagon uses A78-13 as a bias-ply fitment and BR78-13 as a radial fitment, so construction choice is part of the equation here. Owners should confirm which wheel and tire setup is actually on the car before selecting between a traditional bias-ply presentation and a radial-size replacement path.
Bias-Ply to Radial Tire Conversion for the 1974 Ford Pinto
The 1974 Ford Pinto has radial-equivalent options for two of its primary bias-ply sizes. For both 600-13 and A78-13, the available equivalents are 165R13 as an 80-series metric radial, P165/75R13 as a 75-series P-metric radial, and P175/70R13 as a 70-series P-metric radial. These choices step through different sizing conventions and profile families while staying in the same general fitment range. A recommended rim width of 4 to 5 inches applies, and wheel compatibility, overall dimensions, and clearance should be checked before changing from the original bias-ply size.

Best 1974 Ford Pinto Tires for Sale
Available 600-13 products center on BFGoodrich Silvertown Classic Bias Ply tires, with a choice of wide whitewall or narrow whitewall styling. That gives Pinto owners a straightforward way to compare appearance within the correct bias-ply size and 13-inch fitment.
These FAQs focus on the 1974 Ford Pinto’s three primary tire sizes, the differences between body-style fitments, bias-ply versus radial selection, radial-equivalent options for bias-ply sizes, and the wheel, clearance, and condition checks worth making before road use.
Tire Size & Fitment
What tire size fits a 1974 Ford Pinto?
The 1974 Ford Pinto uses three primary tire sizes: 600-13, A78-13, and BR78-13. The correct one depends on the sub-model, because the 2 & 3 Dr. uses 600-13 and A78-13 bias-ply sizes, while the Wagon uses A78-13 bias-ply and BR78-13 radial fitments.
That means the first step is identifying the exact Pinto body style and then confirming what wheel and tire setup is currently on the car. Even though all three sizes use 13-inch rims, the size code and construction still matter, especially when deciding whether to stay with a bias-ply tire or keep a radial-equipped setup.
What size rim does a 1974 Ford Pinto use?
The 1974 Ford Pinto uses 13-inch rims for the tire sizes covered here. That applies across 600-13, A78-13, and BR78-13, so the basic wheel diameter stays consistent even though the tire sizing formats and constructions differ.
Wheel diameter is only part of the fitment picture, so it should not be the only thing checked before ordering tires. The exact tire size, the wheel width, and the car’s body style still need to line up, particularly on a Pinto that may have had wheels changed over the years.
Do all 1974 Ford Pinto sub-models use the same tire size?
No, the 1974 Ford Pinto sub-models do not all use the same tire size. The 2 & 3 Dr. uses 600-13 and A78-13 bias-ply sizes, while the Wagon uses A78-13 bias-ply and BR78-13 radial fitments.
That overlap can make the fitment look simpler than it really is, because A78-13 appears on both sub-models while the other sizes do not. A buyer should confirm the sub-model first, then verify the actual wheel and tire combination on the car so the replacement choice matches the Pinto’s current setup.
Bias-Ply & Radial Options
Is 600-13 a bias-ply or radial tire for the 1974 Ford Pinto?
For the 1974 Ford Pinto, 600-13 is a bias-ply tire size. It uses the older numeric sizing system rather than a radial format, and it appears as one of the primary fitments for the Pinto 2 & 3 Dr.
That makes 600-13 the right starting point for an owner keeping a traditional bias-ply look and feel on a car that uses this size. If a radial alternative is being considered, the next step is comparing the available equivalent sizes to the wheel width and checking for clearance rather than assuming any radial option will substitute automatically.
What radial tire sizes are equivalent to 600-13?
Radial equivalents for 600-13 include 165R13 as an 80-series metric radial, P165/75R13 as a 75-series P-metric radial, and P175/70R13 as a 70-series P-metric radial. The same set of equivalents also applies to A78-13 on the 1974 Ford Pinto.
Each of those options represents a different radial sizing convention, so the choice is not only about rim diameter. A recommended rim width range of 4 to 5 inches is associated with these equivalents, and the vehicle should still be checked for wheel compatibility, overall dimensions, and clearance before moving away from the original bias-ply size.
What should I check before converting my 1974 Ford Pinto from bias-ply to radial tires?
Start by confirming the original bias-ply size on the specific 1974 Ford Pinto sub-model and then matching it to an available radial equivalent such as 165R13, P165/75R13, or P175/70R13 where applicable. The 13-inch rim diameter may stay the same, but wheel width and tire dimensions still need attention.
A careful conversion also means checking the actual wheels on the car, the available clearance at the fenders and steering components, and the overall condition of suspension parts. On an older Pinto, previous wheel changes or ride-height changes can alter what works, so the conversion should be treated as a fitment evaluation, not an automatic swap.
Choosing the Right Tire
What should I consider when choosing a 600-13 tire for a 1974 Ford Pinto?
The main considerations with a 600-13 tire for a 1974 Ford Pinto are confirming that 600-13 is the correct size for the specific sub-model, keeping the bias-ply construction if that is the goal, and selecting the sidewall appearance that suits the car. In this size, BFGoodrich Silvertown Classic Bias Ply options are available.
A buyer can then compare details that affect how the tire presents on the car, including wide whitewall versus narrow whitewall styling and the wheel-width range used by the tire. For a restoration-oriented Pinto, appearance may lead the decision, while a regularly driven car may call for a closer look at the overall setup before finalizing the choice.
What sidewall styles are available for 1974 Ford Pinto tires?
Within the available 600-13 products for the 1974 Ford Pinto, sidewall choices include wide whitewall and narrow whitewall styles. Both are offered in BFGoodrich Silvertown Classic Bias Ply form, giving the buyer a visible appearance choice within the same vintage tire size.
That kind of sidewall difference matters most when the car’s presentation is part of the decision, especially on a restored or carefully preserved Pinto. The sidewall treatment should be chosen only after the correct size is confirmed, since appearance cannot make up for selecting a tire that does not match the car’s proper fitment.
How do I choose between the available 600-13 tires for a 1974 Ford Pinto?
The available 600-13 choices for a 1974 Ford Pinto are both bias-ply BFGoodrich Silvertown Classic Bias Ply tires, so the main difference is sidewall styling rather than a change in basic construction or tire series. One uses a 2.00-inch wide whitewall, while the other uses a 1.00-inch narrow whitewall.
That means the decision comes down to how traditional or understated the tire should look on the car, along with confirming that the wheel matches the tire’s intended width range. Since both are the same core size, the selection is largely visual once fitment and the Pinto’s sub-model have already been verified.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Ford Pinto?
A period-style 1974 Ford Pinto should start with the primary size used by the correct sub-model, whether that is 600-13, A78-13, or BR78-13. For owners staying with a traditional presentation, the bias-ply sizes are the natural place to begin because they preserve the older sizing format and vintage construction style.
The next choice is how closely the tire’s appearance should match the car’s intended era and presentation. When exact originality matters, it is wise to compare the tire choice against model-specific historical references or marque-club guidance, since a correct size alone does not prove a specific sidewall treatment or tire style is exact for every Pinto.
How does tire construction affect the appearance of a restored 1974 Ford Pinto?
Tire construction changes the visual character of a restored 1974 Ford Pinto because bias-ply and radial tires carry different sizing conventions and often present differently on the wheel. On this car, 600-13 and A78-13 reflect vintage bias-ply sizing, while BR78-13 is a radial fitment used on the Wagon.
That difference matters when the goal is a restoration-oriented look rather than simply filling the wheel opening with a tire of the same rim diameter. A Pinto restored around a bias-ply setup will usually call for a different visual approach than one retaining a radial fitment, so construction should be treated as part of the car’s finished appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Ford Pinto?
Yes, modifications can affect tire fitment on a 1974 Ford Pinto even when the replacement tire uses the correct 13-inch rim diameter. Changes such as aftermarket wheels, different wheel widths, suspension alterations, or body modifications can all influence how a 600-13, A78-13, or BR78-13 tire sits and clears.
That is especially important on an older compact car because many examples have been altered over time. A buyer should verify the actual wheel width, inspect fender and steering clearance, and make sure the car still matches the intended tire size before assuming the original fitment will behave the same way on a modified Pinto.
What should I inspect before driving a 1974 Ford Pinto on new tires?
Before driving a 1974 Ford Pinto on new tires, inspect the wheels for the correct diameter and width, confirm proper air pressure, and look over the car for any clearance issues at the fenders, suspension, and steering components. It is also smart to make sure the replacement tires match the correct sub-model fitment.
A short test drive should be approached carefully, with attention to vibration, rubbing, pull, or unusual steering feel. On a collector-era Pinto that may have spent long periods parked, it also helps to inspect wheel hardware, valve stems, and the general condition of suspension and brake components before returning the car to regular road use.
How should 600-13 tires on a collector 1974 Ford Pinto be maintained?
600-13 tires on a collector 1974 Ford Pinto should be maintained with regular pressure checks, visual inspections for cracking, bulges, cuts, and uneven wear, and periodic checks for air loss during storage. Bias-ply tires also deserve extra attention on low-mileage cars that sit for long stretches between drives.
Storage conditions matter just as much as mileage on an older Pinto, so the car should be kept away from prolonged heat, direct sunlight, excess moisture, and ozone sources when possible. Before any longer drive, it helps to recheck inflation, inspect tread and sidewalls closely, and confirm the tires still look sound after storage.
