The 1957 Rambler Ambassador came to market in an era when American automakers were balancing full-size comfort, distinctive styling, and increasingly modern road manners. For owners restoring or maintaining one today, tire choice has a big influence on both stance and character. This exact model uses an 800-14 bias-ply tire on a 14-inch rim, giving it a traditional mid-century fitment profile. Within that size, there is still room to choose among blackwall, narrow whitewall, and wide whitewall presentations, along with period-style series from BFGoodrich, Goodyear, and Universal Vintage Tire. The key is matching the tire to the car's intended appearance, wheel setup, and driving expectations.
Which Tire Size Is Right for The 1957 Rambler Ambassador
The 1957 Rambler Ambassador uses one primary tire size: 800-14. That size is a bias-ply fitment on a 14-inch rim, and the covered 8 Cyl. sub-model uses the same basic size. Once size is confirmed, the real choice becomes sidewall style, tire series, and whether to stay with the original-style bias-ply construction or evaluate one of the available radial equivalents.
An 800-14 is a vintage numeric bias-ply size in which the leading number represents an approximate nominal section width of 8.00 inches, while the final number identifies a 14-inch rim. On a 1957 Rambler Ambassador, this format preserves the traditional bias-ply construction and the visual character expected on a late-1950s American car. Available choices include BFGoodrich, Goodyear, and Universal Vintage Tire, with blackwall, narrow whitewall, and wide whitewall treatments across series such as Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply. It is the right starting point when the goal is period-style fitment and stock-type wheel compatibility.
Sub-model fitment is straightforward here because the covered Rambler Ambassador configuration uses the same primary tire size. Checking the exact sub-model still matters, but tire selection is centered more on construction and appearance than on sorting through multiple factory sizes.

1957 Rambler Ambassador 8 Cyl.
The 1957 Rambler Ambassador 8 Cyl. uses the 800-14 bias-ply tire size. That keeps selection focused on choosing the right sidewall presentation and tire series, or comparing radial-equivalent options if the car's wheel setup and intended road use support a construction change.
Bias-Ply to Radial Tire Conversion for the 1957 Rambler Ambassador
The original 800-14 size has four radial-equivalent choices. Those include 205R14 as an 80-series metric radial, P215/75R14 as a 75-series P-metric radial, P225/70R14 as a 70-series P-metric radial, and 800R14 as a bias-look radial equivalent. Together, they offer a range from traditional metric sizing to a more vintage-style radial presentation. A recommended rim-width range of 5 to 7 inches is associated with these equivalents, and wheel compatibility plus vehicle clearance should be checked before changing construction.

Best 1957 Rambler Ambassador Tires for Sale
Available 800-14 choices span BFGoodrich, Goodyear, and Universal Vintage Tire, with period-style bias-ply options in Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply. The main comparisons are sidewall treatment, brand, tire series, and rim-width specification within the correct 14-inch fitment.
Owners of a 1957 Rambler Ambassador usually want to confirm the correct 800-14 fitment first, then sort through bias-ply versus radial-equivalent choices, sidewall style, and practical checks before putting a collector car back on the road.
Tire Size & Fitment
What tire size fits a 1957 Rambler Ambassador?
The 1957 Rambler Ambassador uses an 800-14 tire size. That is a vintage numeric bias-ply fitment mounted on a 14-inch rim, and the covered 8 Cyl. sub-model uses that same primary size.
The important next step is confirming that the car still has the correct wheel diameter and a stock-type setup. Once that is settled, the decision shifts from finding the right size to choosing the right version of 800-14, including blackwall, narrow whitewall, or wide whitewall styling, or comparing one of the available radial-equivalent sizes.
What size rim does a 1957 Rambler Ambassador use?
The primary tire fitment for a 1957 Rambler Ambassador uses a 14-inch rim. That rim diameter matches the 800-14 tire size, where the final number in the size identifies the wheel diameter the tire is built around.
Rim diameter should be confirmed on the actual car before ordering, especially if the wheels may have been changed over the years. Rim width also matters when comparing specific tires, since some 800-14 products are tied to 5.00 to 6.00-inch widths while some radial-equivalent options reference a broader 5 to 7-inch range.
Does the 1957 Rambler Ambassador 8 Cyl. use the same tire size?
Yes. The covered 1957 Rambler Ambassador 8 Cyl. uses the same 800-14 bias-ply tire size. There is no separate primary size shown here for that sub-model, which keeps the basic fitment question simple.
That means sub-model identification is less about sorting through multiple factory tire sizes and more about making the right style and construction choice. Owners can focus on whether the car calls for a blackwall, narrow whitewall, or wide whitewall look, and whether a traditional bias-ply tire or a radial equivalent better suits the intended use.
Bias-Ply & Radial Options
Is 800-14 a bias-ply or radial tire for the 1957 Rambler Ambassador?
For the 1957 Rambler Ambassador, 800-14 is the primary bias-ply tire size. It is the traditional construction associated with this fitment and it is the format used by the available period-style 800-14 products for the car.
That matters because a bias-ply tire preserves the original-style sizing system and look, while a radial alternative is a separate decision rather than the same thing in another construction. Anyone considering a conversion should check wheel width, overall tire dimensions, and clearance at the fenders and steering components before moving away from the stock-type bias-ply setup.
What radial tire sizes are equivalent to 800-14?
Radial equivalents for 800-14 include 205R14, P215/75R14, P225/70R14, and 800R14. Those represent an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial equivalent, respectively.
Each one gives the Rambler owner a different way to approach a radial conversion, from modern metric sizing to a radial meant to preserve a more traditional visual character. The associated rim-width range is 5 to 7 inches, but equivalent sizing should still be checked against the car's actual wheels, tire clearance, and overall setup before making the change.
What should I check before converting my 1957 Rambler Ambassador from bias-ply to radial tires?
Start by confirming the wheel diameter, wheel width, and the radial-equivalent size being considered for the 1957 Rambler Ambassador. For an 800-14 conversion, the equivalent choices are 205R14, P215/75R14, P225/70R14, and 800R14, with a recommended rim-width range of 5 to 7 inches.
A conversion should also be checked for fender clearance, steering clearance, and suspension condition, especially on an older collector car that may no longer sit exactly as it did when new. The best approach is to treat radial equivalency as a sizing guide, then verify that the car's actual wheel and chassis setup support the change.
Choosing the Right Tire
What should I consider when choosing a 800-14 tire for a 1957 Rambler Ambassador?
The first consideration is staying with the correct 800-14 size and confirming a 14-inch wheel. After that, the main differences among available tires come down to brand, tire series, sidewall treatment, and whether the car is being kept on a traditional bias-ply construction or evaluated for a radial-equivalent alternative.
A restoration-oriented car may call for a different visual presentation than a driver that sees regular road use. It also helps to compare product details such as rim-width specification and maximum load capacity where stated, since those details can affect whether a particular 800-14 tire suits the wheel setup and how the Ambassador will be used.
What sidewall styles are available for 1957 Rambler Ambassador tires?
The available 800-14 tires for a 1957 Rambler Ambassador include blackwall, narrow whitewall, and wide whitewall sidewall styles. Those choices appear across bias-ply offerings from BFGoodrich, Goodyear, and Universal Vintage Tire, giving the car noticeably different visual character without changing the primary size.
Sidewall style is often one of the biggest appearance decisions on a 1950s American car. A blackwall gives a more restrained presentation, while narrow and wide whitewalls create a stronger period-style look. The right choice depends on how the car is being restored or presented, not just on basic fitment, since all three styles can exist within the same 800-14 size.
What brands offer tires for the 1957 Rambler Ambassador?
BFGoodrich, Goodyear, and Universal Vintage Tire all offer 800-14 tires for the 1957 Rambler Ambassador. The available series include Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply, all within the car's primary bias-ply size.
Brand choice should be considered alongside sidewall appearance and wheel compatibility rather than as a shortcut by itself. Since the available tires vary in presentation and in details such as stated rim-width specification, it helps to compare the product characteristics that matter most for the car's intended use, whether that is restoration display, weekend driving, or a more traditional road-going setup.
Restoration & Appearance
Which tire should I choose for a period-style 1957 Rambler Ambassador?
A period-style 1957 Rambler Ambassador starts with the correct 800-14 bias-ply size. From there, the choice usually depends on how traditional the finished car should look, with options in series such as Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply.
For many restorations, the appearance decision is really about sidewall treatment rather than size, since blackwall, narrow whitewall, and wide whitewall versions are available in the same fitment. If exact originality matters beyond a period-style presentation, it is worth comparing the car against marque literature, surviving examples, or restoration references before settling on a specific sidewall look.
How does tire construction affect the appearance of a restored 1957 Rambler Ambassador?
Tire construction changes more than ride and handling character on a restored 1957 Rambler Ambassador; it also changes the way the car presents visually. An 800-14 bias-ply keeps the original-style sizing language and a more traditional look, while an 800R14 bias-look radial is a separate option for owners who want a radial with a vintage-leaning appearance.
That distinction matters most when the goal is an authentically mid-century stance and sidewall profile. A standard metric or P-metric radial can be a useful equivalent, but it may not deliver the same visual impression as a bias-ply tire or a bias-look radial. Construction choice should match the car's restoration purpose as much as its road-use plans.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1957 Rambler Ambassador?
Yes. Modifications can change how a tire fits on a 1957 Rambler Ambassador even when the nominal size remains close to the original 800-14. Aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body repairs can all affect clearance and the way the tire sits in the wheel opening.
That is especially important when considering a radial-equivalent size, since the car may no longer match a stock wheel and chassis layout. Measuring the actual rim diameter and width, then checking steering travel and fender space, is a smarter approach than assuming any equivalent will behave the same way on a modified or partially restored Ambassador.
What should I inspect before driving a 1957 Rambler Ambassador on new tires?
Before driving a 1957 Rambler Ambassador on new tires, inspect the wheels for correct diameter and condition, confirm that the tires are seated properly, and check inflation carefully. It is also wise to look over the valve stems, wheel hardware, and the general condition of the suspension and steering components.
A short, low-speed test drive is a sensible way to confirm that the car tracks properly and that nothing rubs under steering input or suspension movement. Collector cars that sit for long periods also deserve a close look for fluid leaks, brake issues, and any signs that the chassis condition might affect how the new tires perform on the road.
How should 800-14 tires on a collector 1957 Rambler Ambassador be maintained?
800-14 tires on a collector 1957 Rambler Ambassador should be checked regularly for air pressure, tread condition, sidewall cracking, bulges, cuts, and signs of air loss. Even on a car that sees limited mileage, tire condition matters because age and storage can affect road readiness as much as wear does.
Good storage habits help preserve collector tires between drives. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can reduce premature deterioration, and moving the car periodically can help avoid long-term flat spotting. A careful inspection before each season or longer drive is a sound routine for an older Ambassador.
