The 1941 Nash Ambassador came from a period when American automakers still emphasized ride quality, cabin comfort, and strong road presence, and Nash positioned the Ambassador as a substantial upper-range car in that prewar market. For owners today, tire choice is closely tied to the exact engine version, because the 6-cylinder and 8-cylinder cars do not share the same primary size. Both fitments are 16-inch bias-ply tires, with 6.25-16 used on the 6 Cyl. and 650-16 used on the 8 Cyl. Available choices lean heavily toward traditional blackwall and wide whitewall presentations, so the right selection often comes down to matching the car's configuration, restoration style, and intended road use.
Which Tire Size Is Right for The 1941 Nash Ambassador
The 1941 Nash Ambassador uses two primary tire sizes, and the correct one depends on the specific sub-model. Both fitments are bias-ply tires for 16-inch rims, but the 6-cylinder car uses 6.25-16 while the 8-cylinder car uses 650-16. The first step is confirming which Ambassador version you have, then choosing the tire style and product series that best suits a restoration-oriented appearance or regular collector-car driving.
6.25-16 is a numeric bias-ply size in which the first number reflects the tire's nominal section width in inches and the final number indicates a 16-inch rim. On the 1941 Nash Ambassador, this is the bias-ply fitment used on the 6 Cyl. model, so it carries the traditional construction and visual character expected on a prewar car. Buyers looking at this size should focus on keeping the correct sub-model fitment and confirming wheel condition and dimensions before replacement. That matters especially on older vehicles where wheels, suspension parts, or prior replacements may not still match original-era specifications.
650-16 is also a numeric bias-ply size, with the leading number denoting nominal section width and the final number showing fitment for a 16-inch rim. This size belongs to the 1941 Nash Ambassador 8 Cyl. and has the broadest visible selection, including blackwall and wide whitewall styles from brands such as BFGoodrich, Firestone, Coker Classic, Garfield, Lester, Goodyear, STA, Tornel, and Excelsior. Several tire series appear in this size, ranging from classic passenger-car patterns to more specialized truck-style offerings. That makes 650-16 a fitment where both appearance and intended use deserve close attention before choosing a tire.
Tire fitment for the 1941 Nash Ambassador varies by sub-model rather than staying consistent across the full line. Checking whether the car is a 6 Cyl. or 8 Cyl. model is the key step, because each uses a different primary bias-ply size on the same 16-inch rim diameter.

1941 Nash Ambassador 6 Cyl.
The 1941 Nash Ambassador 6 Cyl. uses its own primary 16-inch bias-ply fitment rather than sharing the larger 8-cylinder tire size. For tire selection, that means confirming the car's exact configuration first, then choosing a period-style bias-ply replacement that suits the car's appearance and road-use plans.
The 1941 Nash Ambassador 8 Cyl. uses the larger of the two primary bias-ply fitments offered across this model line. That gives the buyer a wider range of blackwall, wide whitewall, and series choices, so the decision becomes more about intended presentation, wheel compatibility, and how the car will be driven.
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.

Tire Size & Fitment
What tire size fits a 1941 Nash Ambassador?
A 1941 Nash Ambassador uses one of two primary tire sizes, depending on sub-model. The 6-cylinder car uses 6.25-16, while the 8-cylinder car uses 650-16. Both are bias-ply fitments and both mount on 16-inch rims, so the difference is in tire size rather than rim diameter or construction type.
The important step is identifying the exact Ambassador version before ordering tires. A car that has changed hands many times may also have replacement wheels or mixed components, so it helps to confirm the engine-specific model, check the wheel diameter, and compare the tire currently on the car before choosing a replacement.
What size rim does a 1941 Nash Ambassador use?
The 1941 Nash Ambassador uses a 16-inch rim with both primary tire sizes. That applies to the 6.25-16 fitment used on the 6-cylinder model and the 650-16 fitment used on the 8-cylinder model. Rim diameter stays the same even though the two sub-models do not share the same tire size.
Wheel diameter is only one part of fitment on a prewar car. It is still worth checking the actual wheels on the vehicle for width, condition, and any signs that they have been changed over the years. Matching the tire to the correct rim diameter first prevents basic fitment mistakes before sidewall style or brand becomes part of the decision.
Why does the 1941 Nash Ambassador have more than one tire size?
The 1941 Nash Ambassador has more than one tire size because fitment varies by sub-model. The 6 Cyl. version uses 6.25-16, while the 8 Cyl. version uses 650-16. Both are period-style bias-ply tires, but they are not the same size and should not be treated as a single fitment across the whole model line.
That distinction matters because the right tire choice starts with the exact car, not just the model name. Owners should confirm whether the vehicle is a 6-cylinder or 8-cylinder Ambassador, then verify the wheels actually on the car. This is especially important on restored or long-stored cars where substitutions may have been made at some point.
Choosing the Right Tire
What should I consider when choosing a 650-16 tire for a 1941 Nash Ambassador?
Choosing a 650-16 tire for a 1941 Nash Ambassador starts with confirming that the car is the 8 Cyl. model, since that is the sub-model tied to this size. From there, the main differences are construction details within bias-ply offerings, sidewall appearance, tire series, rim-width specifications, load figures where stated, and whether the tire has a passenger-car or truck-style character.
A restoration-minded owner may focus first on blackwall versus wide whitewall presentation, while a road-use buyer may also compare rim-width compatibility and overall product style. Looking closely at the wheel setup helps narrow the field, especially because some 650-16 choices lean more toward traditional passenger-car use and others carry truck-oriented tread or casing characteristics.
What sidewall styles are available for 1941 Nash Ambassador tires?
1941 Nash Ambassador tire options in 650-16 include both blackwall and wide whitewall sidewall styles. That gives owners a choice between a more understated traditional look and a brighter prewar presentation. The available whitewall treatments vary by product line, so appearance differences can be meaningful even within the same basic tire size.
Sidewall style should be chosen with the car's restoration direction and visual balance in mind, not simply by size alone. A dark-sidewall tire can suit a more restrained presentation, while a wide whitewall can shift the car toward a more formal period-style look. Checking old photos, club references, or restoration goals can help settle that appearance decision.
What brands offer tires for the 1941 Nash Ambassador?
The 650-16 fitment for the 1941 Nash Ambassador is available from BFGoodrich, Coker Classic, Firestone, Garfield, Excelsior, Lester, Goodyear, STA, and Tornel. Those offerings span several classic tire series and include both blackwall and wide whitewall styles. Brand choice here is less about a single answer and more about matching the tire's presentation and specification to the car.
Comparing brands makes the most sense after the correct size and sub-model have been confirmed. Once that is settled, look at sidewall treatment, stated rim-width range, load information when shown, and whether the tire follows a passenger-car or truck-oriented pattern. That approach keeps the selection grounded in fitment and appearance rather than just brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1941 Nash Ambassador?
A period-style 1941 Nash Ambassador tire choice starts with the correct sub-model fitment: 6.25-16 for the 6 Cyl. and 650-16 for the 8 Cyl. Because both are bias-ply applications, staying with the proper size and construction preserves the visual character most buyers expect on a prewar car. The remaining choice is usually between blackwall and wide whitewall presentation.
For many restorations, appearance matters nearly as much as fitment, but exact originality should be checked against marque-specific references if that level of detail matters. A wide whitewall can emphasize the formal look of the era, while a blackwall keeps the tire visually quieter. Using the correct size first keeps the car's stance and overall presentation on the right track.
Does correct tire fitment matter for a 1941 Nash Ambassador restoration?
Correct tire fitment matters on a 1941 Nash Ambassador restoration because the car does not use one universal size across all versions. The 6-cylinder and 8-cylinder models differ, even though both use 16-inch bias-ply tires. Getting that distinction right affects not only appearance, but also how authentic the completed vehicle looks to anyone familiar with prewar fitment details.
Restoration-minded owners should confirm the exact sub-model before selecting sidewall style, brand, or tire series. Prewar cars can also carry later replacement wheels, so checking the actual hardware on the vehicle is worthwhile. Once fitment is settled, cosmetic choices such as blackwall versus wide whitewall can be made with far more confidence and far less risk of mismatch.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1941 Nash Ambassador?
Modifications can affect tire fitment on a 1941 Nash Ambassador, even when the car still uses a 16-inch wheel. Aftermarket wheels, changed wheel widths, brake work, suspension changes, or body repairs can all influence how a bias-ply tire sits and clears. That is especially relevant on a prewar car, where long service life often means decades of accumulated changes.
A buyer should confirm more than the tire size stamped on the old casing. Checking actual wheel diameter and width, steering clearance, and space around the fenders helps avoid surprises after installation. That extra inspection is worthwhile whether the goal is a formal restoration, a dependable touring car, or simply putting a long-stored Ambassador back into service.
What should I inspect before driving a 1941 Nash Ambassador on new tires?
Before driving a 1941 Nash Ambassador on new tires, inspect the wheels for damage or corrosion, confirm that the tire size matches the car's exact sub-model, and check inflation carefully. It also helps to look over the suspension and steering components, because worn parts can affect how a fresh bias-ply tire tracks and wears on the road.
A short test drive followed by a second inspection is a smart habit on an older collector car. Listen for rubbing, watch for unusual pull or vibration, and recheck air pressure after the first miles. Prewar cars often see infrequent use, so catching clearance or setup issues early helps preserve both the new tires and the vehicle's road manners.
How should 1941 Nash Ambassador tires be maintained?
1941 Nash Ambassador tires should be maintained with regular pressure checks, periodic visual inspection, and close attention to age-related condition. Even on a lightly driven collector car, sidewall cracking, flat spotting, cuts, bulges, and slow air loss deserve prompt attention. Bias-ply tires also benefit from routine inspection because many prewar cars spend long periods parked between drives.
Storage conditions matter almost as much as mileage on an older vehicle. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires over time. It is also wise to inspect them before every outing, especially before a longer drive, since low annual mileage does not prevent aging or condition-related issues.
