1939 Ford Tire Fitment Guide

1939 Ford vehicles use two tire sizes: 550-16 and 600-16. The 550-16 size fits the 1939 Ford 60 Series, while 600-16 fits the 1939 Ford 85 Deluxe, 1939 Ford 85 Standard, and 1939 Ford Mercury. Both sizes mount on 16-inch wheels. Published rim width ranges 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 means year and make alone are not enough to choose correctly for a 1939 Ford. The first step is to identify whether your car is a 60 Series or one of the 85/Mercury models, then confirm the actual wheel on the car matches the tire's intended width range. If your car has been altered over the years, compare the wheel itself rather than assuming the original configuration is still in place.

On a 1939 Ford, 550-16 is a numeric bias-ply size. The 5.50 designation is the nominal section width in inches, while the 16 indicates the wheel diameter in inches. That size belongs to the 1939 Ford 60 Series in the model range covered here, and the available products in this size are all bias-ply rather than radial.

Modern buyers often expect a metric code, so the older numeric system can look less precise than it really is. On a 1939 Ford 60 Series, the important takeaway is that 550-16 identifies both the general physical scale of the tire and its period construction type. Once that size is confirmed, the next choice is usually blackwall versus wide whitewall, depending on the look you want for the car.

No, not all 1939 Ford models use the same tire size. The 1939 Ford 60 Series uses 550-16, while the 1939 Ford 85 Standard, 1939 Ford 85 Deluxe, and 1939 Ford Mercury use 600-16. All of those are 16-inch bias-ply fitments, but the section width changes with the model group.

That split reflects the different positioning of the models in Ford's 1939 lineup. If you are starting with a project car, body shell, or inherited vehicle, the model name matters before you compare products or sidewall styles. Once the model is identified, the fitment path becomes much clearer and you can focus on the appearance and specification details that matter for your particular build or restoration.

1939 Ford tires are available with both blackwall and wide whitewall sidewall styles in the sizes covered here. The 550-16 size for the 1939 Ford 60 Series includes blackwall and wide whitewall options, and the 600-16 size for the 1939 Ford 85 Standard, 85 Deluxe, and Mercury also includes both styles. That gives buyers flexibility without changing the underlying bias-ply construction.

Sidewall style can strongly affect how a prewar Ford presents visually. A blackwall usually gives a more restrained, workmanlike look, while a wide whitewall pushes the car toward a more dressed, period-show appearance many collectors want for late-1930s passenger cars. If authenticity matters for formal judging, compare your chosen whitewall width and overall look against period photos, marque references, and the way your specific model would have been trimmed.

Several brands offer tires for 1939 Ford vehicles in the sizes listed here. 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 products shown for both sizes are bias-ply tires, so the brand choice is more about style, series character, and exact product specification than a switch in construction type.

That variety is useful because different restorations call for different visual cues. Some owners want a traditional American-brand presentation, while others are comparing sidewall treatment, load figures, or the fit of a specific reproduction series. Keeping the brand conversation within the correct size for your model is the key step, because a well-matched brand in the wrong size is still the wrong starting point for a 1939 Ford.

For the 1939 Ford applications that use 600-16, both Firestone and BFGoodrich offer bias-ply wide whitewall tires with the same listed rim width range of 4.00 to 4.50 inches and the same listed maximum load of 1400 pounds at 32 psi. Their product weights differ, with the Firestone example listed at 24 pounds and the BFGoodrich example at 21 pounds. Both are period-style options for the 85 Standard, 85 Deluxe, and Mercury models.

That means the practical difference between them is less about basic fitment and more about brand identity, visual preference, and the character you want in the finished car. For a restoration-minded owner, details like whitewall presentation and the overall look of the tread and sidewall can matter as much as the headline specification. If you are comparing two period-style choices, review the exact series and appearance rather than assuming all 600-16 wide whitewalls are identical.

1939 Ford tire rim width requirements depend on the size used by the model. Available 550-16 products list a rim width range of 3.25 to 4.00 inches, and available 600-16 products list a rim width range of 4.00 to 4.50 inches. Both sizes use 16-inch wheel diameter, but the approved width range changes with the tire size.

That overlap at 4.00 inches is useful, but it should not be treated as a blanket interchange rule for every wheel and tire combination. Measure the wheel actually on the car and compare it with the intended tire size before final selection. On a prewar Ford, it is common for cars to have had wheels swapped over the decades, so the safest approach is to verify the hardware in front of you rather than rely only on model name.

The listed 1939 Ford tire products do not show a universal tube marking across every option, so tube details should be confirmed on the specific tire you choose. The sizes covered here are traditional bias-ply applications on 16-inch wheels, which often leads restorers to pay close attention to wheel condition, valve hardware, and whether the exact tire-and-wheel combination is intended to run with a tube.

The practical step is to confirm tube requirements before installation rather than after the tires arrive. On an older wheel, the decision is affected not only by the tire itself but also by the wheel design, surface condition, and how the car will be used. If your 1939 Ford still wears original-style wheels, inspect them carefully and treat the tube question as part of the full wheel-and-tire setup rather than a separate afterthought.

Original 1939 Ford wheels can only be considered for both tire sizes in terms of diameter, because both 550-16 and 600-16 mount on 16-inch wheels. Width is the limiting factor: 550-16 products list 3.25 to 4.00 inch rim widths, while 600-16 products list 4.00 to 4.50 inch rim widths. A 16-inch wheel that matches one size in diameter may still be too narrow or too wide for the other.

That is why the answer depends on the exact wheel fitted to the car, not just on the fact that both tires are 16-inch sizes. A 1939 Ford owner looking at a wheel swap or mixed-parts project should measure the wheel and identify the model before choosing tires. Diameter compatibility is only the first checkpoint; the wheel still has to fall within the proper width range for the size you intend to run.

A stored 1939 Ford should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber prematurely. Because the available 1939 Ford fitments here are bias-ply, they can be more prone to flat-spotting during long periods of inactivity than a modern radial. Clean floors, stable temperatures, and proper inflation all help protect the tires while the car is parked.

If the car will sit for an extended period, move it periodically or support it in a way that reduces long-term stress on one contact patch. Bias-ply collector tires often smooth out after a short drive, but repeated static storage can still leave visible aging and shape changes over time. Storage habits matter just as much as mileage on a low-use prewar Ford, especially if the car is kept mainly for shows or seasonal drives.

Tires on a 1939 Ford are usually judged more by age and condition than by tread wear alone. A good working rule for collector vehicles is to evaluate tires closely once they are around five to seven years old and to treat the ten-year mark as a serious point for replacement consideration, even if the tread still looks serviceable. The DOT date code on the tire is the reference point for age, not the restoration date of the car.

That matters because many prewar Fords cover limited annual mileage and can appear healthy while the rubber is quietly aging. Sidewall cracking, hardening, vibration, or a change in how the car tracks can all signal that the tire has aged out before the tread is gone. A fresh-looking bias-ply tire that has spent years in poor storage conditions may deserve more caution than a lightly used tire that has been stored properly.

Tires on a 1939 Ford should be inspected before every drive, with a more thorough check before longer outings or event travel. Look for sidewall cracking, tread separation, cuts, bulges, irregular wear, and any loss of air pressure. On a collector car using period-style tires, valve stems and the condition of the spare deserve the same attention as the four road tires.

Frequent inspection is especially important because many vintage cars spend more time parked than driven. A quick walk-around before a local cruise may catch a developing issue before it becomes a roadside problem, and a longer pre-trip check gives you time to address concerns calmly. On a 1939 Ford, tire condition is only one part of road readiness, but it is one of the easiest and most important things to evaluate regularly.

The 1939 Ford 60 Series uses 550-16 in the fitment covered here, and a bias-ply tire is the era-correct construction type for a 1939 American passenger car. That aligns with what restorers expect for a prewar Ford, where bias-ply was the normal construction in regular use. The available products in this size follow that period pattern rather than shifting into later radial conventions.

For a factory-authentic restoration, the size and the overall sidewall presentation both matter, not just whether the tire physically mounts on the wheel. Blackwall and wide whitewall choices can lead the car toward different historical looks depending on trim, market, and how the car is being restored. If you are preparing a car for marque judging, confirm the exact finish expected for your body style and trim level with Ford and Mercury specialists before final selection.

Correct tire fitment matters noticeably when a 1939 Ford is judged for authenticity. Size, construction type, and sidewall style all affect whether the car presents as period-correct, and judges familiar with prewar American cars will often notice when a tire looks visually out of character. On a 1939 Ford, choosing 550-16 for a 60 Series or 600-16 for an 85 or Mercury model is part of getting the basic stance and proportion right.

The farther a tire moves from the expected size and visual treatment, the more likely it is to stand out on a serious restoration. A wide whitewall may suit one restoration goal, while a blackwall may suit another, but either choice should be consistent with the car's intended presentation. Event standards differ, so if trophies or formal judging are the goal, compare your chosen tire against club guidance and period reference photos before the car goes on the field.

For the 1939 Ford 60 Series, Firestone and BFGoodrich both offer 550-16 bias-ply options with wide whitewall styling. The Firestone example lists a rim width range of 3.25 to 4.00 inches, a maximum load of 840 pounds at 32 psi, and a weight of 19 pounds. The BFGoodrich example is also a wide whitewall bias-ply tire in the same size, with a listed weight of 16 pounds.

That makes them comparable in appearance category while still leaving room for meaningful differences in listed specification and brand character. A restorer choosing between the two will usually look beyond the fact that both are 550-16 wide whitewalls and consider the exact visual effect and setup details that matter on a smaller prewar Ford. Comparing the specific series rather than just the size name is the best way to make an informed authenticity-minded choice.

1939 Ford tires can be appropriate for highway driving when the tire size, condition, inflation, and vehicle condition are all in order. The products listed here are bias-ply tires, and one 600-16 option carries an H speed rating, which corresponds to a 130 mph ceiling. That speed figure does not mean a 1939 Ford should be driven anywhere near that range; on a prewar car, braking, steering, suspension condition, and overall chassis behavior usually become the real limiting factors long before the tire does.

For normal collector-car road use, the more important question is whether the tires are fresh, properly fitted, and suited to the wheel and model. A sound 1939 Ford on correctly matched tires can be very enjoyable on secondary roads and moderate highway stretches, but every trip should be approached with respect for the car's era and mechanical design. Smooth inputs, sensible cruising speed, and careful pre-drive checks matter more than chasing the highest number on the sidewall.

Inflation pressure on a 1939 Ford should be set by the vehicle's factory guidance and the specific tire's rated figures rather than by a one-size-fits-all number. Among the available products, 550-16 and 600-16 examples include maximum load figures at 32 psi, including 840 pounds at 32 psi for one 550-16 Firestone tire and 1400 pounds at 32 psi for certain 600-16 BFGoodrich, Coker Classic, and Firestone tires. Those are tire ratings, not automatic operating recommendations for every 1939 Ford application.

The practical approach is to start with the pressure recommendation appropriate to your model and then confirm it remains suitable for the exact reproduction tire you choose. Pressure that is too high or too low can affect steering feel, tread wear, and ride quality on a bias-ply prewar car very quickly. Keep all four tires matched, check pressure when cold, and recheck after long storage before assuming the tires are still where you left them.

Before taking a 1939 Ford on a longer drive, inspect each tire for cracking, cuts, bulges, uneven wear, and proper inflation, and make sure the spare is usable as well. Confirm the wheel and tire size on the car match the model, especially on a car that may have had parts swapped over the years. A longer-drive inspection should also include valve stems, wheel fasteners, and a quick look for anything that suggests the tire has shifted, rubbed, or lost air since the last outing.

That tire check should be part of a broader pre-drive routine suited to a prewar automobile. Cooling system condition, brakes, steering play, fluid levels, and lighting are all worth reviewing before the trip begins. When the car is sorted and the tires are in good shape, a 1939 Ford is much easier to enjoy confidently, and small issues are far better caught in the garage than on the side of the road.
