Franklin Airman Tires

Franklin Airman sits in an interesting corner of early American luxury-car history, spanning the late 1920s into the early 1930s, when Franklin’s air-cooled engineering and upscale positioning gave the marque a distinct identity. Cars from this period often reflect a fast-moving transition in wheel and tire practice, and Franklin Airman is no exception. Tire selection is not especially straightforward here because the listed fitments move from 20-inch rims in 1928 to 19-inch rims in 1933 and then 17-inch rims in 1934, with multiple sizes appearing in some years. The first thing to confirm on any Franklin Airman is the actual rim diameter on the car before narrowing down the correct tire size.

Franklin Airman Tire Size Guide

Franklin Airman fitments span 5 distinct sizes across 1928 to 1934, and the most important change is wheel diameter: the listings move from 20-inch rims in 1928 to 19-inch rims in 1933, then to 17-inch rims in 1934. Franklin Airman also uses antique diameter-by-section sizing on some early applications, where the leading number in the size code is the tire’s overall outside diameter rather than the wheel diameter. That difference matters because two sizes can look similar on paper while fitting entirely different rims.

30X5.771928Antique diameter-by-section

30X5.77 is an early Franklin Airman size used in 1928. In this format, 30 indicates an overall tire diameter of about 30 inches, 5.77 indicates the section width, and the wheel diameter is not in the size code itself. Choose 30X5.77 only for a 1928 Franklin Airman that specifically calls for that larger-section early size, and verify the actual rim diameter on the wheel before proceeding.

30X51928Antique diameter-by-section

30X5 is another 1928 Franklin Airman fitment and is the early size in this group with available products. Here, 30 refers to the tire’s outside diameter, 5 refers to section width, and the listed products fit a 20-inch rim rather than a 30-inch wheel. Use this size for a 1928 car equipped for 20-inch rims; available products are bias-ply, and a tube is required.

650-191933Antique diameter-by-section

650-19 is the Franklin Airman size used for 1933. In this period format, 6.50 is the nominal section width with the decimal omitted, while 19 is the rim diameter used by the available products. Choose 650-19 for 1933 applications on 19-inch wheels; the available products are bias-ply and a tube is required.

700-171934Antique diameter-by-section

700-17 is one of the Franklin Airman sizes listed for 1934. The 7.00 figure is the nominal section width, and the available products are built for 17-inch rims. Choose 700-17 only for a 1934 Franklin Airman fitted with the narrower of the two 17-inch options; the products are bias-ply and a tube is required.

750-171934Antique diameter-by-section

750-17 is the larger 17-inch Franklin Airman size listed for 1934. The 7.50 figure identifies the nominal section width, and the products fit a 17-inch rim. Choose 750-17 for 1934 Franklin Airman applications that call for the wider 17-inch tire, paying close attention to whether the car is using passenger-car or heavier-duty style equipment; the products are bias-ply and a tube is required.

Franklin Airman Tires by Year

Franklin Airman production changed from 20-inch to 19-inch wheels in 1933, then to 17-inch wheels in 1934, so rim diameter should be confirmed on the car before selecting a tire. Both 1928 and 1934 list more than one size, which means year alone is not always enough to identify the correct fitment. The leading number on early Franklin Airman size codes can describe overall tire diameter or nominal section width rather than wheel size, so the rim diameter must be matched separately.

Frequently Asked Questions

The Franklin Airman FAQ focuses on the wheel-diameter changes across the production span, the meaning of period size codes, and how to sort out years that show more than one listed fitment. It also covers sidewall choices, brand options, and long-term care for low-use collector tires.

Size Basics & Fitment

Franklin Airman uses five listed sizes across the years covered here: 30X5.77 and 30X5 for 1928, 650-19 for 1933, and 700-17 plus 750-17 for 1934. Among the available products, 30X5 fits a 20-inch rim, 650-19 fits a 19-inch rim, and both 700-17 and 750-17 fit 17-inch rims. All listed products are bias-ply constructions.

The practical takeaway is that year and wheel diameter need to be checked together. A 1928 Franklin Airman does not share the same rim size as the later cars, and 1934 can require either of two different 17-inch sizes. Start with the year, confirm the wheel diameter on the car, then compare the section width called for by the specific application.

On a Franklin Airman, 30X5 is an antique diameter-by-section size. The 30 refers to the tire’s approximate overall outside diameter in inches, while the 5 refers to section width. It does not mean the tire fits a 30-inch wheel; the available 30X5 products in this range fit a 20-inch rim.

That distinction matters because antique tire markings can be misleading to modern buyers who are used to the last number indicating wheel diameter. If you are working with a 1928 Franklin Airman, read the sidewall carefully and confirm the actual wheel size before matching a replacement. That helps avoid confusing an overall tire measurement with the rim dimension.

A 1934 Franklin Airman can use either 700-17 or 750-17, and both sizes fit 17-inch rims. The difference is the tire’s nominal section width, with 750-17 being the wider of the two. That means the split is not a wheel-diameter change within the year, but a same-rim-size variation.

For a buyer or restorer, that means the specific configuration of the car matters more than the year alone. Check the existing wheel and tire, period service information, or marque references to determine whether the car was set up for the narrower or wider 17-inch fitment. Matching that width is important for stance, clearance, and period appearance.

Franklin Airman uses more than one rim diameter across the years covered here. The available 1928 30X5 products fit 20-inch rims, 1933 650-19 uses a 19-inch rim, and the 1934 sizes 700-17 and 750-17 use 17-inch rims. On early antique-style size markings, the first number is not always the wheel diameter.

That makes the wheel itself the first thing to inspect before choosing a tire. Measure the rim or verify the stamping on the wheel rather than relying on a quick read of the tire size alone. On a Franklin Airman, getting the rim diameter right narrows the fitment question immediately and prevents confusion between early and later applications.

Buying the Right Tire

Confirming the correct Franklin Airman tire starts with the car’s year, then the wheel diameter, then the actual size marking if an old tire is still present. The covered range includes 20-inch, 19-inch, and 17-inch rim applications, and some years list more than one size. That means a year-only match is not always precise enough.

Use the year listing as a starting point, then compare the car’s current wheel, any surviving sidewall markings, and period reference material for the exact application. On a 1934 Franklin Airman especially, identifying whether the car needs 700-17 or 750-17 is the key step. That approach keeps the selection tied to the individual car rather than a broad model label.

Franklin Airman tires in this range are available in blackwall, wide whitewall, and double-whitewall styles. Blackwall appears across several sizes, wide whitewall is available in 30X5, 650-19, 700-17, and 750-17, and double-whitewall appears on selected 17-inch balloon-style sizes. Those choices give restorers both restrained and more dressed-up period looks.

The right sidewall style depends on how the Franklin Airman is being restored and presented. A blackwall generally gives the most understated period appearance, while wide whitewall and double-whitewall options can suit a more formal or show-oriented presentation. Match the sidewall treatment to the era of the car and the look you want, while keeping the underlying size and rim diameter correct.

The Franklin Airman sizes covered here are offered by Hartford, Firestone, Lester, Excelsior, Ensign, BFGoodrich, Tornel, and STA. Not every brand appears in every size, and the largest concentration of choices is in the 650-19 and 750-17 ranges. Some brands focus on passenger-car styles, while others appear in heavier-duty 750-17 offerings.

Brand choice usually comes after size, rim diameter, and intended use are settled. Once the Franklin Airman’s correct fitment is identified, compare the available brands by sidewall style, tire series, and the character of the build rather than assuming every product serves the same purpose. That is especially important in 750-17, where both passenger-style and truck-oriented products appear.

Franklin Airman tires in this range appear in several series, including Hartford Aero, Firestone Classic Bias Ply, Firestone Balloon, Lester Classic Bias Ply, Comp H, Ensign B5, Silvertown Classic Bias Ply, Tornel Classic Truck, and Super Transport. Those series reflect different period styles and intended uses rather than one universal specification. Some are clearly passenger-car oriented, while others in 750-17 fall into heavier-duty truck or transport categories.

For most Franklin Airman restorations, the useful distinction is between passenger-car bias-ply lines and the heavier-duty 750-17 offerings. If the goal is a period passenger-car appearance, focus on the series associated with classic bias-ply or balloon passenger tires. If the car carries wheels or use requirements that point toward the heavier 750-17 family, pay close attention to section width, rim width, and the overall character of the tire.

Maintenance & Longevity

A Franklin Airman should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and petroleum contamination. Proper inflation matters even when the car is not being driven regularly, because underinflation encourages sidewall stress and flat spotting on bias-ply tires. Clean wheels and dry floors also help preserve both the tire casing and the tube environment.

If the Franklin Airman will sit for long stretches, roll it occasionally or support it in a way that reduces constant load on one patch of the tire. Bias-ply collector tires benefit from gentle use and consistent storage habits more than from long idle periods. A car that is stored carefully is easier to inspect and generally kinder to rare period-size tires.

Tires on a Franklin Airman should be inspected before every drive and more thoroughly at regular intervals during the driving season. Look for pressure loss, sidewall cracking, tread separation signs, uneven wear, valve-stem issues, and any movement of the tire on the rim that could affect the tube. Older bias-ply constructions reward frequent visual checks because problems can develop long before tread is worn out.

A careful inspection routine is especially important on a collector car that may sit for weeks between outings. Checking the tires before the car leaves the garage helps catch age-related changes while they are still minor. On a Franklin Airman, that inspection should also include the wheel and rim band condition, since the tire and tube system depend on the whole assembly being sound.

A Franklin Airman tire should be replaced when age, cracking, hardening, impact damage, casing distortion, or persistent air-loss issues appear, even if the tread still looks usable. Collector tires often age out before they wear out, and bias-ply constructions can become structurally suspect long before they look obviously exhausted. Tread depth alone is never the full measure of serviceability on a low-mileage historic car.

For that reason, replacement decisions on a Franklin Airman should be guided by condition and age rather than mileage. Any tire that shows significant weather checking, irregular shape, or repeated tube problems deserves close evaluation before further use. A conservative replacement schedule is usually the wiser choice on a car whose tires may spend more time aging in place than accumulating miles.

Restoration & Authenticity

Franklin Airman originally used period-type bias-ply tires in the sizes associated with its year and wheel diameter, but the covered range includes more than one series and more than one fitment path. Available series include Hartford Aero, Firestone Classic Bias Ply, Firestone Balloon, Lester Classic Bias Ply, Comp H, Ensign B5, and Silvertown Classic Bias Ply. That tells you the car belongs in the early bias-ply and balloon-tire era rather than a modern radial context.

For a precise restoration, the exact year and the car’s wheel setup should guide the final choice. A 1928 Franklin Airman belongs to a different wheel-and-size world than the 1933 and 1934 cars, and 1934 adds a same-year size split. Marque references and surviving original examples are the best way to narrow the historically correct series and sidewall treatment for an individual car.

Correct tire fitment absolutely affects how a Franklin Airman presents in restoration judging and in the eyes of knowledgeable collectors. Size, rim diameter, sidewall style, and overall tire profile all influence whether the car sits with the right proportions for its year. A visibly wrong tire can make an otherwise careful restoration look less authentic.

The practical point is that correctness is about more than simply finding a tire that mounts. A 20-inch 1928 application, a 19-inch 1933 application, and a 17-inch 1934 application each give the Franklin Airman a different visual character, and mixing those eras changes the car’s stance. Matching the tire to the car’s year and intended presentation helps preserve both authenticity and perceived quality.

Franklin Airman tires in this range are offered in blackwall, wide whitewall, and selected double-whitewall styles. Blackwall is the most restrained and broadly period-friendly choice, while whitewall treatments can suit more formal presentations from the era. The correct look depends on the specific year, the car’s trim character, and how strictly original the restoration is meant to be.

A restorer should choose sidewall style only after the correct size and rim diameter are settled. Once that is established, the visual decision becomes easier: blackwall for a more conservative period appearance, or whitewall if the car’s presentation and historical context support it. On a Franklin Airman, sidewall style is a finishing detail, but it strongly shapes first impressions.

Safety & Road Use

A properly selected and properly maintained bias-ply tire can be suitable for public-road use on a Franklin Airman within the normal limitations of a pre-war collector car. Safety depends on more than the tire itself: wheel condition, tube condition, inflation, alignment, brake performance, steering condition, and the age of the tire all matter. A Franklin Airman should be treated as a historic automobile, not as a modern highway car.

That means road use should be thoughtful and conservative. Before regular driving, make sure the tire size matches the wheel diameter and the car’s year, and have the complete running gear reviewed if there is any doubt about its condition. A Franklin Airman on correct bias-ply tires can be enjoyable on the road, but it should always be driven with period-appropriate expectations.

Before driving a Franklin Airman, check tire pressure, visible sidewall condition, tread condition, valve stems, wheel fasteners, and any signs of tube-related air loss. Also look for uneven wear or a changed stance that might suggest one tire is soft or that the car is carrying mismatched sizes. Because Franklin Airman fitments vary by year and wheel diameter, confirming that all four tires belong to the same intended setup is important.

A short pre-drive routine can prevent most tire-related surprises on a collector car. Walk around the Franklin Airman, inspect each casing closely, and drive only after the car feels settled and properly inflated. If the car has been sitting, the first miles should be especially gentle while you listen and feel for any vibration, pull, or other sign that the tires need closer attention.

A Franklin Airman running on period-type bias-ply tires should be driven at moderate, conservative speeds that suit both the tire design and the car’s overall mechanical character. These tires are meant to preserve the feel and appearance of an early-1930s automobile, not to duplicate modern high-speed touring behavior. Smooth operation, heat control, and mechanical sympathy matter more than keeping up with fast modern traffic.

In practical use, that means choosing roads and driving conditions that let the Franklin Airman travel comfortably rather than pushing it to sustained high-speed work. Avoid abrupt steering inputs, hard braking, and long high-heat runs when possible. The best rule is to drive the Franklin Airman at a pace that feels relaxed for both the car and the tire, with extra caution on older roads, crowned pavement, and in hot weather.
