1938 Ford Tire Fitment Guide

1938 Ford vehicles use two different tire sizes depending on model line. The 1938 Ford 60 Series uses 550-16, while the 1938 Ford 85 Series uses 600-16. Both are bias-ply sizes built for 16-inch rims. Rim-width recommendations shown within the available products run from 3.25 to 4.00 inches for 550-16 and from 4.00 to 4.50 inches for 600-16.

That split means a 1938 Ford owner should confirm the model before choosing a tire, even though both sizes share the same wheel diameter. The smaller 60 Series and the larger 85 Series are not interchangeable tire applications simply because they are both 1938 Fords. Once the correct size is identified, the remaining decisions are usually about sidewall appearance and which bias-ply product best suits the car's restoration goals.

On a 1938 Ford, 550-16 is an older numeric bias-ply tire size. The 550 portion refers to the tire's nominal section width in period sizing language, and the 16 identifies the wheel diameter in inches. For 1938 Ford applications, that size belongs to the 60 Series. Available products in this size are bias-ply rather than radial, which is consistent with the era.

Understanding that older numeric code helps keep a prewar Ford restoration on the right track. A buyer comparing modern tire markings to period Ford fitments can easily mistake 550-16 for a universal 1938 Ford size, but it is tied to the smaller 60 Series model line. If your car is a 60 Series, 550-16 is the proper place to start before deciding between blackwall and whitewall presentation.

No, 1938 Ford models do not all use the same tire size. The 60 Series uses 550-16, while the 85 Series uses 600-16. Both are 16-inch bias-ply fitments, but the section size changes with the model line. That distinction reflects the fact that Ford offered more than one passenger-car specification under the same make and year.

This is one of those prewar fitment details that matters before you go any further in the selection process. If a car has changed hands several times or has been restored in the past, it is wise to verify the model designation and compare the current wheel and tire markings before replacing anything. Starting with the correct model will narrow the choices quickly and prevent mixing 60 Series and 85 Series applications.

A 1938 Ford owner should not choose between 550-16 and 600-16 as alternatives for the same car, because the two sizes are tied to different model lines. The 60 Series uses 550-16, and the 85 Series uses 600-16. Both available sizes are bias-ply, so this is not a bias-versus-radial decision. It is first a model-identification decision.

Once you know which 1938 Ford you have, the choice becomes much simpler. Owners of a 60 Series can focus on 550-16 products, while 85 Series owners should stay with 600-16. From there, the real preference is usually visual: blackwall for a plainer working-car look or whitewall for a more dressed prewar presentation. Choosing by model first keeps the car's stance and proportions in the proper range for its Ford series.

1938 Ford tires are available in both blackwall and wide whitewall styles across the sizes used by the year. In 550-16 for the 60 Series, available products include blackwall and wide whitewall versions. In 600-16 for the 85 Series, the same sidewall categories appear. That gives owners a period-appropriate visual choice without changing away from bias-ply construction.

Blackwall generally suits a more restrained, utilitarian prewar look, while wide whitewall better matches a dressier restoration style many collectors prefer on late-1930s American cars. Which one is most authentic can depend on body style, trim level, and how the car is being presented. If show accuracy matters, compare your car against period photos or consult a Ford marque specialist before settling on whitewall width.

Several brands offer tires for 1938 Ford applications. The 550-16 size is available from Excelsior, Avon, BFGoodrich, and Firestone. The 600-16 size is available from BFGoodrich, Coker Classic, Avon, and Firestone. All of the listed options for these 1938 Ford fitments are bias-ply products sized to the original-style 16-inch wheel applications.

Brand choice on a prewar Ford often comes down to the balance between historical look, preferred sidewall treatment, and the exact product line available in your model's size. Some owners prioritize a familiar American-brand appearance, while others focus on a particular whitewall presentation or a touring-oriented product line. Narrow the field by confirming your Ford series and size first, then compare the brands available within that exact fitment.

1938 Ford tire rim-width needs depend on the size. Available 550-16 products show a recommended rim-width range of 3.25 to 4.00 inches. Available 600-16 products show a recommended rim-width range of 4.00 to 4.50 inches. Both sizes fit 16-inch rims, but they do not share the same full rim-width range.

That difference is important when replacing tires on a car with older wheels or wheels that may not be original to the model. A 16-inch diameter match alone is not enough. Measure the wheel or verify it against known factory-correct hardware before mounting new tires. If the wheel sits near the edge of the approved range for your chosen size, it is worth confirming the specific tire product's fit characteristics before moving ahead.

1938 Ford tire listings here are all bias-ply products, but the tire markings shown do not identify a uniform tube designation across every available product. That means tube use should be confirmed against the exact tire you choose and the wheel you intend to run. On a prewar Ford with original-style steel wheels, tube use is often part of the final mounting decision rather than something to assume by size alone.

The practical step is to inspect the wheel condition, valve-hole style, and any manufacturer markings on the specific tire before assembly. A collector car that still uses original or restored prewar wheels may call for a different setup than one running later replacement wheels. Treat tube choice as part of the complete wheel-and-tire package, not just as a generic rule attached to 550-16 or 600-16.

Original 1938 Ford wheels can only be shared across both tire sizes if they meet the correct 16-inch diameter and the proper rim-width range for the specific model's tire. The 60 Series size, 550-16, is shown with a 3.25 to 4.00 inch rim-width range, while the 85 Series size, 600-16, is shown with a 4.00 to 4.50 inch range. The overlapping point is narrow rather than broad.

That means some 16-inch wheels may physically match the diameter but still be better suited to one Ford series than the other. If your car has mixed wheels, swapped hubs, or parts gathered over many decades, measure before assuming interchangeability. Keeping the tire matched to both the model and the wheel width will preserve the proper look and help avoid setup compromises that are easy to overlook on a prewar car.

A stored 1938 Ford should be kept out of direct sunlight and away from ozone-producing equipment such as electric motors, battery chargers, welders, and compressors. The storage area should stay dry and reasonably stable in temperature. Because 1938 Ford fitments here are bias-ply tires, they are more prone to flat spotting during long static periods than a modern radial would be.

Moving the car periodically or slightly changing the tire's contact patch can help reduce set-in flat spots on collector cars that spend long stretches parked. Some owners also use stands during winter layups, but the suspension should be supported thoughtfully rather than letting the chassis hang unnaturally. Good storage habits matter as much as tread depth on a lightly used prewar Ford because age and environment often end a tire's service life first.

Tires on a 1938 Ford usually age out before they wear out, especially on collector cars that see limited annual mileage. A sensible rule is to begin evaluating them closely at around five to seven years of age and to treat about ten years as a serious replacement point regardless of remaining tread. The DOT date code, if present on the tire, is the practical way to verify age.

A prewar Ford may spend most of its time indoors and still have tires that look presentable while the rubber has hardened with time. Sidewall cracking, loss of flexibility, and reduced confidence at speed can all appear before the tread is gone. Age-based replacement thinking is especially important for hobby cars because infrequent use can disguise deterioration that would be obvious on a daily-driven vehicle.

Tires on a 1938 Ford should be inspected before every drive and again before any extended outing or tour. Look for sidewall cracks, tread separation signs, cuts, bulges, and any loss of pressure since the last use. Valve stems should be checked closely as well, especially on an older wheel-and-tire assembly where age rather than mileage is usually the concern.

Short local drives can make an old tire seem healthy simply because it has not been stressed for long. A more thorough inspection before a regional event or highway trip gives you time to catch small issues before they become roadside problems. Make the spare part of the routine too, since a collector car's spare is often the oldest tire on the vehicle and the least likely one to get regular attention.

The 1938 Ford 60 Series uses 550-16, and for a car of this era the original-type construction would have been bias-ply rather than radial. That aligns with the available fitments here, which are all bias-ply in this size. Original-equipment branding could vary by market and delivery, so the key authenticity markers are the correct size, period-appropriate construction, and the right sidewall treatment for the way the car is being restored.

Owners restoring a 1938 Ford 60 Series for judging usually start with the correct 550-16 size and then compare blackwall versus whitewall appearance against factory literature, period photography, or marque-club guidance. A nicely restored car can still look off if the tire profile or sidewall presentation does not match the era. For body-style or market-specific questions, Ford club resources remain the best final authority.

Correct tire fitment matters a great deal when showing a 1938 Ford because judges and knowledgeable enthusiasts notice size, construction type, and sidewall style immediately. A 60 Series wearing 600-16 tires or an 85 Series wearing 550-16 tires would look wrong to anyone familiar with the model split. Sidewall presentation can matter too, since a blackwall and a wide whitewall create very different period impressions.

For local cruise nights, personal preference may carry more weight than strict historical accuracy. In formal concours or marque judging, however, a tire that is visually out of character can undermine an otherwise strong restoration. If the car is being prepared for serious competition, verify the expected sidewall treatment and any event-specific standards before the final tire choice, especially if the car's history includes prior cosmetic updates.

For the 1938 Ford 85 Series in 600-16, both BFGoodrich and Firestone offer wide whitewall bias-ply tires with the same listed rim-width range of 4.00 to 4.50 inches and the same listed maximum load figure of 1400 pounds at 32 psi. The Firestone listing carries a 3.25-inch whitewall description, while the BFGoodrich listing carries a 3.50-inch whitewall description. The listed weights also differ, with BFGoodrich at 21 pounds and Firestone at 24 pounds.

Those differences do not change the base fitment, but they can affect the look of the finished car and the owner's brand preference. A slightly different whitewall width can change the visual balance of a prewar Ford, especially on a darker paint color. When comparing two period-style options in the same size, pay close attention to the sidewall presentation first and then to the product details that shape how authentic you want the final restoration to appear.

1938 Ford tires can be suitable for highway use when they are the correct size, in good condition, and operated within the limits shown for the specific product. The available 600-16 Avon offering carries an H speed rating, which corresponds to 130 mph, while the other listed products do not show a speed letter in the size marking. Even so, tire capability is only one part of the equation on a prewar Ford.

A 1938 Ford's brakes, suspension design, steering feel, and overall mechanical condition are usually more limiting than the tire itself at normal modern road speeds. The practical goal is not maximum rated speed but stable, predictable service within the car's real-world operating envelope. Before regular highway use, make sure the tires are fresh, pressure is correct, and the rest of the chassis is sorted to the same standard as the tire choice.

Inflation pressure on a 1938 Ford should be set according to the vehicle's factory guidance and the specific reproduction tire's construction and rating, not by copying one number across every size. Among the listed products, 550-16 Firestone shows 840 pounds at 32 psi, while several 600-16 products show 1400 pounds at 32 psi and the 600H16 Avon shows 1,433 pounds. Those figures are tire ratings, not a blanket recommendation for every Ford application.

The best practice is to start with the pressure specified for the car in factory literature, then make sure it stays within the tire maker's allowed range for that exact product. A smaller 60 Series tire and a larger 85 Series tire should not automatically be run the same way just because they share a 16-inch rim diameter. Matching pressure to the actual tire and the actual Ford model helps preserve handling balance and wear.

Before a longer drive in a 1938 Ford, inspect all four tires and the spare for cracks, cuts, bulges, unusual wear, and pressure loss. Confirm that each tire matches the correct model size, with 550-16 for the 60 Series or 600-16 for the 85 Series. Check valve stems carefully and make sure wheel condition is sound, especially on older restored or original steel wheels.

A pre-drive inspection should also include the broader systems that matter on any prewar automobile: brakes, steering free play, wheel bearings, cooling, and basic fluid levels. The point is to treat the tires as part of the whole car rather than as an isolated item. Long trips put sustained heat and load into parts that may have spent months at rest, so a careful walk-around and mechanical once-over are well worth the time.
