The 1957 Morgan Series sits squarely in the British sports car tradition, with lightweight construction, exposed mechanical character, and a driving experience that feels far more immediate than larger postwar automobiles. Tire choice on a car like this affects not just appearance, but steering feel and the overall period character of the chassis. The 1957 Morgan Series uses a 500-16 bias-ply tire on a 16-inch rim, keeping the fitment firmly in vintage territory. Available options in this size lean toward a traditional blackwall presentation and a specialty performance-oriented tire series. For a restoration-minded owner, the real focus is preserving the correct look and proportions while confirming wheel width and intended road use.
Which Tire Size Is Right for The 1957 Morgan Series
The 1957 Morgan Series uses one primary tire size: 500-16. That is a bias-ply fitment on a 16-inch rim, and the covered Series II sub-model uses the same size as well. With fitment settled, the real decision becomes choosing the right tire within that vintage size, especially if appearance, wheel-width compatibility, and intended use all matter to the car's final setup.
A 500-16 tire uses the older numeric bias-ply sizing system, where the first number refers to nominal section width in inches and the final number identifies the wheel diameter. On the 1957 Morgan Series, that format preserves the narrow, tall vintage profile expected on a lightweight British sports car of the period. In this size, the available choice is a Firestone Dirt Track tire with a blackwall sidewall and ribbed front design, giving it a distinctly traditional and competition-influenced look. It is the size to evaluate if the goal is maintaining authentic proportions while checking wheel width and intended driving use carefully.
Tire fitment is straightforward across the covered 1957 Morgan Series sub-model range. The Series II uses the same primary 500-16 bias-ply size, so the main task is confirming wheel condition, width, and the type of driving the car is expected to see.

1957 Morgan Series II
The 1957 Morgan Series II uses the same 500-16 bias-ply tire fitment as the broader model line. That keeps selection focused on choosing the right period-style tire within that size and confirming that the wheel measures correctly for the available rim-width range.
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 1957 Morgan Series Tires for Sale
Available 500-16 options for the 1957 Morgan Series center on a Firestone bias-ply tire from the Dirt Track series. The product uses a blackwall sidewall and carries a 4.00 to 5.00 inch rim-width range, giving buyers a focused but very specialized vintage choice.
Owners of a 1957 Morgan Series usually need clear answers on 500-16 fitment, 16-inch rim compatibility, bias-ply construction, appearance, and the basic checks to make before putting a lightly used vintage sports car back on the road.
Tire Size & Fitment
What tire size fits a 1957 Morgan Series?
The 1957 Morgan Series uses a 500-16 tire size. This is a vintage numeric bias-ply size mounted on a 16-inch rim, and it suits the narrow, traditional tire profile associated with a lightweight British sports car from the period.
That makes size selection fairly simple, but condition and wheel details still matter. A Morgan that has seen restoration work, wheel changes, or long storage should have its actual rim diameter and width checked before a new tire is chosen, especially since vintage-size tires can be less forgiving of mismatched wheels than many modern applications.
What size rim does a 1957 Morgan Series use?
The 1957 Morgan Series uses a 16-inch rim with its 500-16 tire size. In available product fitment for this size, the usable rim-width range runs from 4.00 to 5.00 inches, which is an important detail on a narrow vintage wheel setup.
Rim diameter alone is not the whole story on an older car. A wheel can still be the correct 16-inch diameter but fall outside the appropriate width range, or it may have been replaced during the car's life. Measuring the wheel before mounting tires helps avoid profile distortion, clearance problems, and unnecessary stress on a bias-ply casing.
Does the 1957 Morgan Series II use the same tire size?
Yes. The 1957 Morgan Series II uses the same 500-16 bias-ply tire size as the covered 1957 Morgan Series fitment. That keeps the sizing question straightforward and places the focus on choosing the right tire within that established vintage format.
Even with shared sizing, it is still worth checking the actual wheels on the car. Older Morgans are often maintained, restored, or modified over time, and a car wearing replacement wheels may need wheel-width confirmation before a new 500-16 tire is mounted. That is especially important when keeping the car's original visual balance intact.
Choosing the Right Tire
What should I consider when choosing a 500-16 tire for a 1957 Morgan Series?
Start with the basics: correct size, bias-ply construction, and 16-inch rim compatibility. The available 500-16 option for the 1957 Morgan Series uses a blackwall sidewall, belongs to Firestone's Dirt Track series, and is intended for a very traditional, specialty vintage presentation.
After size is confirmed, think about how the car will actually be used. A Morgan kept for shows, occasional drives, or period-style presentation may call for different priorities than one expected to see regular road miles. Wheel width should be measured carefully, and the car's suspension, steering clearance, and overall condition should be reviewed before installation.
What sidewall styles are available for 1957 Morgan Series tires?
The available 500-16 fitment for the 1957 Morgan Series uses a blackwall sidewall. That gives the car a clean, understated vintage appearance and fits naturally with the narrow-tire look expected on many postwar British sports cars.
Sidewall treatment plays a major role in how an older car reads visually, even when the tire size stays the same. On a small, lightweight Morgan, a blackwall keeps the presentation simple and purposeful. Buyers focused on restoration appearance should also consider tread style, tire series character, and whether the car's final look leans more roadgoing or competition-inspired.
What brands offer tires for the 1957 Morgan Series?
Firestone is the available brand in 500-16 for the 1957 Morgan Series. The offered tire comes from the Dirt Track series and uses bias-ply construction, which keeps the fitment aligned with the car's vintage sizing and overall period character.
Brand alone should not be the only deciding factor on a specialty size like this. The more useful comparison points are tire construction, sidewall style, rim-width compatibility, and whether the tire's character matches the way the Morgan will be displayed or driven. On a collector-era sports car, those details matter as much as the name on the sidewall.
Restoration & Appearance
Which tire should I choose for a period-style 1957 Morgan Series?
A 500-16 bias-ply tire is the right starting point for a period-style 1957 Morgan Series because it preserves the vintage size format, narrow section, and overall visual character associated with the car. In available fitment, that points to a blackwall Firestone Dirt Track tire.
Appearance-minded buyers should look beyond size alone and consider how the tread style and sidewall presentation suit the car's finished personality. A restoration intended to reflect a roadgoing sports car may emphasize a clean traditional look, while a more competition-flavored presentation may welcome a stronger specialty-tire character. Exact originality should be checked against marque-specific historical references.
Does correct tire fitment matter for a 1957 Morgan Series restoration?
Yes, correct tire fitment matters a great deal on a 1957 Morgan Series restoration. The car's proportions are defined by relatively narrow vintage tires, so changing size, construction, or wheel width too far from the intended setup can alter its stance, steering feel, and visual balance.
That does not mean every restored car must be finished the same way, but it does mean the tire should support the restoration goal. A period-style build benefits from keeping the 500-16 bias-ply format in place, while any wheel or fitment deviation deserves careful measuring first. Tire choice is part of the restoration story, not just a maintenance item.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1957 Morgan Series?
Yes. Any change to wheels, wheel width, suspension height, springs, steering components, or body clearances can affect tire fitment on a 1957 Morgan Series, even when the tire remains the original 500-16 size. Older specialty cars often have long histories, so assumptions can be risky.
A modified Morgan should have its actual wheel measurements and clearances verified before new tires are installed. Small cars with narrow fenders can react noticeably to seemingly minor changes, and a bias-ply tire needs to sit properly on the wheel. Checking lock-to-lock steering clearance and full suspension travel is especially worthwhile before road use.
What should I inspect before driving a 1957 Morgan Series on new tires?
Inspect the wheels, valve stems, lug hardware, and general suspension condition before driving a 1957 Morgan Series on new tires. It is also smart to confirm that the tires are seated correctly, inflated appropriately for the application, and free from any signs of shipping damage or mounting-related issues.
A vintage sports car that spends much of its life parked deserves extra caution on its first miles back out. Listen for rubbing, watch for unusual steering behavior, and recheck air pressure after the initial drive. It also helps to inspect wheel bearings, brakes, and steering joints so the new tires are not masking other issues in the chassis.
How should 500-16 tires on a collector 1957 Morgan Series be maintained?
500-16 tires on a collector 1957 Morgan Series should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and uneven wear, and stored away from prolonged sunlight, heat, moisture, and ozone sources. Low annual mileage does not eliminate the need for routine tire checks on an older car.
Collector vehicles often age their tires through time and storage conditions as much as through road use. Rolling the car periodically, keeping the wheels clean, and checking for slow air loss can help preserve the tires between drives. Before any longer outing, confirm pressure, tread condition, and sidewall health rather than relying on appearance alone.
