The 1931 Nash 80 Series comes from an era when American automakers balanced style, comfort, and engineering confidence in the years just before streamlined design began to reshape the market. For owners restoring or maintaining one today, tire choice plays a visible role in how the car sits, drives, and presents itself. This Nash uses a 550-19 bias-ply tire on a 19-inch rim, which keeps the fitment rooted in pre-war tire construction and proportions. Available choices include a traditional blackwall or a 3.25 inch wide whitewall in BFGoodrich's Silvertown Classic Bias Ply series. The key decision is usually appearance and restoration character, while still confirming wheel condition and roadworthy tire setup.
Which Tire Size Is Right for The 1931 Nash 80 Series
The 1931 Nash 80 Series uses one primary tire size: 550-19. That means the main fitment question is straightforward, with a bias-ply tire designed for a 19-inch rim, including the covered 8 Cyl. sub-model. From there, the decision shifts to sidewall appearance, restoration presentation, and making sure the wheel itself remains compatible with the tire's intended rim dimensions.
A 550-19 size is a vintage numeric bias-ply designation in which the 5.50 figure refers to the tire's nominal section width in inches and the 19 identifies the wheel diameter. On the 1931 Nash 80 Series, this size preserves the tall, narrow profile and construction style associated with early 1930s passenger cars. Available choices in this size include BFGoodrich Silvertown Classic Bias Ply tires with either a blackwall or a wide whitewall sidewall treatment. For most owners, selecting 550-19 is less about changing size and more about choosing the appearance that best suits the car's restoration goals and intended road use.
Fitment is straightforward across the covered 1931 Nash 80 Series sub-models because the same primary tire size is used. Checking the exact sub-model still helps confirm that the car remains on the expected wheel and tire setup before a replacement is chosen.

The 1931 Nash 80 Series 8 Cyl. uses the same 550-19 bias-ply fitment as the model core, so size selection stays simple. The practical choice is whether to keep a more understated blackwall look or move toward a wide whitewall presentation while confirming that the existing 19-inch wheels remain correct for the tire.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1931 Nash 80 Series Tires for Sale
Available 550-19 options center on BFGoodrich's Silvertown Classic Bias Ply series, with a choice between blackwall and wide whitewall sidewall styling. Both share the same basic size, bias-ply construction, 19-inch rim diameter, and restoration-oriented character.
Owners of a 1931 Nash 80 Series usually want clarity on the correct 550-19 fitment, 19-inch rim compatibility, sidewall appearance choices, and what to inspect before putting a pre-war car back on the road.
Tire Size & Fitment
What tire size fits a 1931 Nash 80 Series?
The 1931 Nash 80 Series uses a 550-19 tire size. This is a numeric bias-ply size used on a 19-inch rim, and it is the primary fitment for the covered vehicle and its 8 Cyl. sub-model.
That makes the size decision fairly simple compared with later vehicles that may have multiple factory-type fitments. The next step is confirming that the car still has the expected wheel setup, then choosing the sidewall appearance and product style that best matches a restoration-focused presentation or regular collector-car driving.
What size rim does a 1931 Nash 80 Series use?
The 1931 Nash 80 Series uses a 19-inch rim with its 550-19 tire fitment. Available tires in this size are built around that rim diameter and are intended for narrow vintage wheel dimensions rather than later, wider passenger-car wheels.
Wheel diameter should be verified on the car before ordering, especially if the vehicle has been apart for restoration or has changed hands over time. Rim condition matters just as much on an early car, so it is wise to inspect for corrosion, damage, and proper bead-seat condition before mounting new tires.
Does the 1931 Nash 80 Series 8 Cyl. use the same tire size?
Yes. The covered 1931 Nash 80 Series 8 Cyl. uses the same 550-19 bias-ply tire size as the model core. That keeps fitment straightforward and avoids the size-sorting issues that come with vehicles that changed tires by trim or wheel package.
Even with shared sizing, a quick check of the actual wheels on the car is still worthwhile. Early vehicles are often restored over many decades, and wheel substitutions can happen, so confirming 19-inch rims and suitable wheel width helps keep the replacement tire choice aligned with the car's present setup.
Choosing the Right Tire
What should I consider when choosing a 550-19 tire for a 1931 Nash 80 Series?
Start with the correct 550-19 size, bias-ply construction, and 19-inch rim fitment. For this Nash, the biggest differences among available choices are visual rather than dimensional, since the options stay within the same size family and tire series.
Appearance, wheel compatibility, and intended use usually guide the final decision. A blackwall gives a more understated presentation, while a wide whitewall adds stronger period-style visual impact. It also helps to compare rim-width compatibility, load capacity at its stated pressure, and the overall condition of the car's wheels before mounting new tires.
What sidewall styles are available for 1931 Nash 80 Series tires?
The available 550-19 tires for the 1931 Nash 80 Series come in blackwall and wide whitewall styles. Both retain the same vintage bias-ply size and overall fitment approach, so the difference is mainly in how the tire complements the car's exterior presentation.
That choice often comes down to the character of the restoration. A blackwall can suit a more restrained, utilitarian look, while a wide whitewall creates a more formal pre-war appearance. Either way, the sidewall style should be chosen after the correct size and wheel compatibility are confirmed, not as a substitute for proper fitment.
What rim-width specifications should I compare when choosing 1931 Nash 80 Series tires?
The available 550-19 tires for the 1931 Nash 80 Series are built for a rim-width range of 2.50 to 3.00 inches. That narrow specification reflects the wheel proportions typical of an early 1930s passenger car and should be taken seriously during selection.
Matching the tire to the correct wheel width helps preserve proper tire shape and mounting behavior. An owner should confirm the actual wheel dimensions on the car, especially if the wheels have been replaced, repaired, or mixed over time. That step matters as much as choosing between blackwall and wide whitewall appearance.
Restoration & Appearance
Which tire should I choose for a period-style 1931 Nash 80 Series?
A 550-19 bias-ply tire is the right starting point for a period-style 1931 Nash 80 Series because it preserves the vintage size format, tall profile, and construction type associated with the car's era. Within that fitment, the main visual choice is blackwall versus wide whitewall.
That appearance decision depends on the character of the restoration and the look the owner wants the car to project. If exact historical presentation matters down to trim and delivery style, it is smart to compare the tire choice against marque references, period photography, or other vehicle-specific restoration sources before settling on a sidewall treatment.
Does correct tire fitment matter for a 1931 Nash 80 Series restoration?
Yes, correct tire fitment matters greatly on a 1931 Nash 80 Series restoration because tire size and construction strongly affect stance, wheel-to-tire proportion, and the overall visual character of a pre-war car. A 550-19 bias-ply tire keeps the car within the proper vintage fitment framework.
Using the right fitment also helps avoid a restored car looking visually out of scale at the wheel openings. Beyond appearance, the owner should confirm that the wheels remain sound and dimensionally appropriate, since older rims can develop issues over time even when the car has been stored or only driven occasionally.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1931 Nash 80 Series?
Yes. Even though the normal fitment is a 550-19 bias-ply tire, modifications can change what needs to be checked on a 1931 Nash 80 Series. Wheel substitutions, brake work, suspension repairs, or altered ride height can all affect clearance and overall wheel compatibility.
A pre-war car may also have replacement parts from different periods of its life, so the current setup should be inspected rather than assumed. Confirm wheel diameter, wheel width, and basic clearance at the fenders and steering components before mounting new tires, especially if the car has been restored in stages or assembled from long-stored parts.
What should I inspect before driving a 1931 Nash 80 Series on new tires?
Before driving a 1931 Nash 80 Series on new tires, inspect the wheels for structural condition, check that the tires are mounted in the correct 550-19 size, and make sure inflation matches the tire's intended use. The suspension and steering should also be examined for looseness or worn components.
A collector car that has seen long storage deserves a broader walk-around before road use. Look for air loss, rubbing, sidewall damage from installation, and any sign that the tires are not seated properly on the rims. A short, careful test drive can reveal tracking, vibration, or clearance issues before a longer outing.
How should 550-19 tires on a collector 1931 Nash 80 Series be maintained?
550-19 tires on a collector 1931 Nash 80 Series should be maintained with regular pressure checks, visual inspection of the tread and sidewalls, and periodic examination for cracking, cuts, bulges, or uneven wear. Low annual mileage does not remove the need for inspection on an older car.
Storage conditions matter just as much as mileage. Keeping the car away from prolonged sunlight, moisture, excess heat, and ozone sources helps preserve tire condition over time. It is also wise to inspect the wheels and valve hardware during routine maintenance, since the tire and rim work together as a complete roadworthy assembly.
