1932 Franklin Tire Fitment Guide

1932 Franklin vehicles use two different tire sizes, and they are tied to specific models rather than shared across the full lineup. The Franklin 12 uses 750-17 bias-ply tires on 17-inch rims, while the Franklin 16 Airman uses 650-19 bias-ply tires on 19-inch rims. Rim-width guidance appears on some products, including 4 inches and 5.50 to 6.00 inches within 750-17 offerings and 3.25 to 3.50 inches within 650-19 offerings.

That means the first step is identifying the model correctly before comparing brands or sidewall styles. A 1932 Franklin owner who starts with year and make alone can easily end up looking at the wrong diameter tire, so it is worth checking the actual wheel and the car’s model designation before choosing a product.

On a 1932 Franklin, 750-17 is a numeric bias-ply tire size. The 7.50 portion identifies the nominal section width in inches, while the 17 identifies the wheel diameter in inches. For 1932 Franklin applications, that size belongs to the Franklin 12 and is offered in bias-ply construction with Blackwall, Double-Whitewall, and Wide Whitewall sidewall choices.

Numeric sizing like this is typical of the prewar era and reads very differently from modern metric tire markings. If your Franklin 12 is being restored for an authentic period look, 750-17 keeps you in the proper vintage format, and the main choice becomes which sidewall appearance best matches the way the car will be finished and presented.

No, 1932 Franklin models do not all use the same tire size. The Franklin 12 uses 750-17 tires on 17-inch rims, while the Franklin 16 Airman uses 650-19 tires on 19-inch rims. Both are bias-ply sizes, but they are not interchangeable because the wheel diameters are different and the fitment is model-specific.

That difference matters before you ever get to brand selection or whitewall preference. If the car’s history is unclear or the wheels may have been changed over the decades, verify both the model and the actual rim diameter before ordering, especially on a prewar car where restoration changes can blur what was originally fitted.

1932 Franklin tires are available in several period-appropriate sidewall treatments depending on size. The 750-17 size for the Franklin 12 is offered in Blackwall, Double-Whitewall, and Wide Whitewall form, while the 650-19 size for the Franklin 16 Airman is offered in Blackwall and Wide Whitewall versions. All of the listed choices remain within bias-ply construction, which suits the era of the car.

Sidewall style is often the visual choice that changes the character of a restoration most noticeably. Blackwalls generally suit a more restrained prewar presentation, while whitewall treatments create a fuller luxury appearance, so the right decision depends on how the particular 1932 Franklin is being restored and the look you want once the car is on its wheels.

1932 Franklin tire options come from more than one brand, but the lineup varies by size. The 750-17 size used on the Franklin 12 is available from Firestone and BFGoodrich, while the 650-19 size used on the Franklin 16 Airman is available from Firestone and Lester. All of the available products are bias-ply tires suited to prewar fitment and appearance.

Brand choice on a car like a 1932 Franklin usually comes down to sidewall appearance, series styling, and how closely a buyer wants the tire’s visual character to match the rest of the restoration. Once the model and size are confirmed, compare the sidewall treatment and any rim-width or load markings within that size instead of assuming every brand option is identical.

Within the 1932 Franklin 12’s 750-17 size, Firestone Balloon and BFGoodrich Silvertown Classic Bias Ply differ in sidewall treatments and some listed specifications. Firestone Balloon appears in Blackwall and Double-Whitewall forms, with examples listing a 4-inch rim width and load figures up to 1870 pounds at 40 psi. BFGoodrich Silvertown Classic Bias Ply appears in Blackwall and Wide Whitewall forms, with one listing showing 5.50 to 6.00 inch rim widths and 1646 pounds at 36 psi.

Those differences make it worth comparing the exact product rather than choosing only by brand name. On a Franklin 12, one owner may prioritize a particular whitewall look, while another may be matching an existing wheel setup, so the sidewall style and rim-width guidance should be reviewed together before settling on a specific 750-17 tire.

Rim-width guidance varies by size and by the specific tire offered for 1932 Franklin vehicles. In 750-17 for the Franklin 12, listed products include a 4-inch rim width on some Firestone Balloon tires and 5.50 to 6.00 inches on one BFGoodrich Silvertown Classic Bias Ply listing. In 650-19 for the Franklin 16 Airman, listed Firestone Balloon products show a 3.25 to 3.50 inch rim-width range.

That spread is a reminder to match the exact tire to the actual wheel instead of treating every product within a given size as identical. Prewar wheels can be changed, restored, or mixed over time, so measuring the wheel and checking the specific tire’s fitment guidance is the safest way to avoid setup issues.

1932 Franklin tires are offered here in bias-ply form, but the individual product markings shown for these sizes do not include tube-type or tubeless notation. On a prewar car such as a 1932 Franklin, original-style wheel construction often leads owners toward tube use, especially when retaining factory-type rims, but the tire itself should still be checked for its specific sidewall marking before final installation.

The practical step is to decide tube fitment as part of the wheel-and-tire assembly plan rather than as an afterthought. If your Franklin still carries original-style wheels, inspect the rims carefully and confirm the tire’s own tube guidance before mounting, especially if the car will see regular road use rather than occasional display duty.

A 1932 Franklin should be stored away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing sources that accelerate sidewall aging. Keep the car in a dry, stable environment and maintain proper inflation while it sits. Because 1932 Franklin tires are bias-ply, they are more prone to temporary flat-spotting after long static periods than a modern radial would be.

Periodic movement helps reduce flat-spot set and keeps the tire from resting on the same footprint for months at a time. If the car will be parked for an extended season, many owners either roll it occasionally or support it in a way that reduces load, while still keeping suspension and storage practices appropriate to the vehicle.

Tire life on a 1932 Franklin is usually governed more by age than by mileage, since many prewar cars see limited annual use. A good rule is to begin evaluating collector-car tires closely once they are around five to seven years old and to treat about ten years as a serious replacement point regardless of how much tread remains. The DOT date code is the reference point for that age calculation.

A Franklin that is driven only to shows can still age its tires out long before it wears them out. Sidewall condition, storage history, and how well the tires have held pressure matter just as much as mileage, so age checks should be part of regular maintenance even when the car appears to have lightly used tires.

Tires on a 1932 Franklin should be inspected before every drive and again before any extended outing. Look for cracking in the sidewalls, cuts, bulges, irregular tread wear, and pressure loss, all of which matter on a prewar car that may spend more time parked than driven. The spare deserves the same attention, since it may be just as old as the tires on the car.

That habit matters even more if the car is used for tours rather than short local trips. If your Franklin is fitted with tube-type assemblies, valve stems and tube condition should be part of the inspection routine as well, because age-related failures often show up first in those supporting components rather than in obvious tread wear.

A 1932 Franklin 12 would have originally been fitted with bias-ply tires, since radial passenger-car fitments were not part of normal American production practice in that period. The correct size for the Franklin 12 is 750-17, and current offerings in that size stay within the proper bias-ply format for a prewar luxury car. Original-equipment branding could vary by market and delivery history, so size and construction are the first points to get right.

For a restoration, that means 750-17 bias-ply is the foundation of an era-correct presentation, while sidewall treatment becomes the next decision. If the car is being judged at a high level, a Franklin marque specialist or club resource is the best place to confirm whether a particular whitewall treatment matches the exact body style and historical presentation you are aiming for.

Correct tire fitment matters a great deal when showing a 1932 Franklin because judges and knowledgeable enthusiasts notice size, construction, and sidewall style quickly. A Franklin 12 wearing 650-19 tires or a Franklin 16 Airman wearing 750-17 tires would be visibly incorrect, and a construction type outside the period would also stand out on a car judged for authenticity. Whitewall width and sidewall treatment can influence the car’s overall historical presentation as well.

Even when an event is not strict concours, the tires strongly affect how complete the restoration feels. Getting the right numeric size and proper bias-ply construction in place first gives you the correct visual stance, and then you can refine the sidewall appearance to suit the body style, the restoration theme, and the standards of the club or judging body involved.

In the 1932 Franklin 16 Airman’s 650-19 size, Firestone Balloon and Firestone Classic Bias Ply differ mainly in series presentation and in the listed fitment details that accompany some products. Firestone Balloon appears in Blackwall and Wide Whitewall form, with examples showing a 3.25 to 3.50 inch rim-width range and one load figure of 1430 pounds at 36 psi. Firestone Classic Bias Ply appears in Blackwall form in the same size without those added rim-width or load details shown alongside it.

That makes the comparison less about basic size fitment and more about the exact look and specification detail you want to follow. On a 1932 Franklin 16 Airman, the right choice may hinge on whether you want a blackwall or whitewall presentation and whether the listed rim-width guidance aligns neatly with the wheels on the car.

1932 Franklin tires in these applications are bias-ply products, and no speed ratings are shown for the listed 750-17 or 650-19 offerings. On a prewar car, the tire is only one part of the highway-use picture, because braking, steering, suspension condition, wheel integrity, and the overall mechanical state of the car are just as important as the tire itself. A well-maintained Franklin used within sensible speeds can be toured, but it should still be treated as a prewar automobile rather than a modern highway cruiser.

The right approach is to match road use to the age and design of the car, then inspect the tires carefully before longer runs. Fresh, properly fitted bias-ply tires can serve well in collector use, but the driver should allow for vintage handling behavior and keep the whole car in proper mechanical condition before expecting relaxed long-distance performance.

Inflation pressure for 1932 Franklin tires should be matched to the specific size, product, and vehicle guidance rather than copied across the entire make. Some 750-17 products list 1870 pounds at 40 psi or 1646 pounds at 36 psi, and one 650-19 product lists 1430 pounds at 36 psi. Those figures are tire ratings, not a blanket recommendation for every Franklin application.

The best practice is to start with the factory vehicle recommendation from period literature or trusted Franklin references, then make sure the selected reproduction tire’s rated limits are respected. Using a pressure from one size on the other, or treating a maximum rated pressure as the default running pressure, can lead to a car that rides or handles poorly.

Before taking a 1932 Franklin on a longer drive, inspect each tire for sidewall cracking, cuts, bulges, uneven wear, and proper cold inflation. Check the spare as carefully as the four road tires, since a decades-old spare can look good while still being unready for service. On a prewar car, wheel condition and valve-stem condition also deserve close attention before setting out.

That tire inspection should be part of a broader tour-prep routine that includes brakes, steering, cooling airflow, and fuel-system checks appropriate to an air-cooled Franklin. Tires are often the first concern because they are visible, but on a car of this age the safest long-drive preparation comes from treating the entire chassis and running gear as a system.
