The 1927 Flint E80 Series comes from the closing years of Flint as a General Motors companion make, giving it a distinct place in late-1920s American motoring. Cars from this period depend heavily on proper tire proportions, sidewall profile, and construction to look right and drive as intended at vintage touring speeds. For the 1927 Flint E80 Series, the primary fitments are 32X6.20 and 650-20, both bias-ply sizes for 20-inch rims. Available choices lean toward traditional blackwall and wide whitewall presentation, with both passenger-style and truck-style series in the mix. The right decision centers on matching the vehicle's exact wheel setup and the appearance you want for restoration or road use.
Which Tire Size Is Right for The 1927 Flint E80 Series
The 1927 Flint E80 Series uses two primary tire sizes, and both are bias-ply fitments built around a 20-inch rim. Because the same sub-model can appear with either size, the first step is confirming the wheel and tire setup already on the car before choosing between a more antique-style sizing convention and a numeric bias-ply replacement.
The size 32X6.20 uses an older diameter-by-section format, where 32 refers to the approximate overall tire diameter in inches and 6.20 refers to the approximate section width. It is a bias-ply fitment that suits the tall, narrow tire profile expected on a late-1920s vehicle like the Flint E80 Series. This format appeals to owners who want a distinctly early-car look and proportion rather than a later numeric sidewall designation. Before choosing it, confirm that the car is set up for this exact sizing convention and that the mounted wheel arrangement matches the tire's intended use.
The size 650-20 is a numeric bias-ply size, with 6.50 indicating nominal section width and 20 identifying the rim diameter in inches. On the 1927 Flint E80 Series, it provides a traditional bias-ply replacement path in a format many vintage and truck-oriented products still use. Available choices include Firestone, Denman, and Deka, with blackwall options, a wide whitewall version, and series such as Firestone Classic Bias Ply, Firestone Classic Truck, Highway Classic Truck, and Deka Classic Truck. This size is the practical choice when the car already uses 20-inch wheels set up for 650-20 fitment and the buyer wants to compare appearance and tire character within that range.
Sub-model fitment is straightforward here because the covered 6-cylinder E80 Series uses the same two primary bias-ply tire sizes. Checking the sub-model still matters, but the bigger task is confirming which of the two established size conventions is already on the car.

1927 Flint E80 Series 6 Cyl.
The 1927 Flint E80 Series 6 Cyl. uses the same two primary bias-ply tire sizes found on this vehicle line, so the fitment question is less about trim differences and more about the wheel-and-tire setup on the individual car. Tire selection then comes down to choosing the right size convention, sidewall appearance, and series for restoration goals or touring use.
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.

Owners of a 1927 Flint E80 Series usually need clarity on the two accepted tire sizes, 20-inch rim fitment, bias-ply construction, sidewall appearance, and what to inspect before putting a vintage car back on the road.
Tire Size & Fitment
What tire size fits a 1927 Flint E80 Series?
The 1927 Flint E80 Series uses two primary tire sizes: 32X6.20 and 650-20. Both are bias-ply fitments, and the covered 6-cylinder sub-model can be associated with either size rather than one single universal tire for every surviving car.
That makes the real fitment step confirming what is actually on the vehicle now, especially if the car has been restored, re-wheeled, or converted over the years. Check the current wheel setup, sidewall markings, and overall tire profile before choosing a replacement, since both sizes are period-appropriate but not the same sizing system.
What size rim does a 1927 Flint E80 Series use?
The 1927 Flint E80 Series uses a 20-inch rim with its primary tire fitments. The numeric 650-20 size states that rim diameter directly, and the vehicle's supported rim diameter remains 20 inches across the covered fitments.
Rim diameter is only one part of the check on a vintage car. Wheel width, bead configuration, and any later wheel substitution can affect which tire is appropriate, so it is worth measuring the wheel and verifying how the current tire sits on it before moving ahead with a new bias-ply tire.
What does 32X6.20 mean on a 1927 Flint E80 Series?
On a 1927 Flint E80 Series, 32X6.20 is an antique diameter-by-section size. The first number refers to an approximate overall tire diameter of 32 inches, while 6.20 refers to the approximate section width rather than the wheel diameter.
That format looks unfamiliar to many modern buyers because it predates later numeric and metric sizing systems. The important takeaway is that 32X6.20 describes a tall, narrow vintage bias-ply tire, so replacement should be matched by correct sizing convention and wheel setup instead of assuming it works like a modern passenger-car size.
Choosing the Right Tire
What should I consider when choosing a 650-20 tire for a 1927 Flint E80 Series?
Start with the correct size, bias-ply construction, and 20-inch wheel compatibility. From there, the meaningful differences in 650-20 come from brand, tire series, sidewall treatment, and whether the tire is more passenger-oriented in appearance or leans toward a truck-style tread and overall presentation.
A Flint headed for restoration display may call for a different visual character than one intended for regular touring on vintage roads. Comparing rim-width compatibility where stated, load figures where stated, and the look of blackwall versus wide whitewall will help narrow the choice without turning the decision into guesswork.
What sidewall styles are available for 1927 Flint E80 Series tires?
The available 650-20 options include both blackwall and wide whitewall sidewall styles. That gives the 1927 Flint E80 Series owner a choice between a more understated working look and a brighter, more formal vintage presentation.
Sidewall style affects appearance far more than fitment, but it has a strong influence on how the finished car reads. A wide whitewall often suits a restoration-oriented build, while blackwall can better match a simpler touring or utility-minded look. The best choice depends on the character you want without assuming one sidewall treatment was universal.
What brands offer tires for the 1927 Flint E80 Series?
For the 1927 Flint E80 Series, available 650-20 products come from Firestone, Denman, and Deka. Those options remain within bias-ply construction, but they differ in sidewall style, tire series, and whether the tire presents more like a classic passenger tire or a truck-oriented vintage pattern.
Brand choice should be part of a larger comparison rather than the whole decision. It helps to look at the series offered under each brand, the visual effect of blackwall or wide whitewall, and whether the wheel and intended use line up with the tire's general character before choosing a final replacement.
Restoration & Appearance
Which tire should I choose for a period-style 1927 Flint E80 Series?
A period-style 1927 Flint E80 Series should start with one of its established bias-ply sizes, either 32X6.20 or 650-20, depending on the wheel and tire setup already on the car. That keeps the tall vintage profile and construction style that suit a late-1920s automobile.
The final choice often comes down to how original in appearance the owner wants the car to feel. Blackwall and wide whitewall treatments create very different visual results, and exact restoration standards can vary, so marque-specific references and period photos are worth consulting when originality matters more than general vintage style.
How does tire construction affect the appearance of a restored 1927 Flint E80 Series?
Tire construction matters because the 1927 Flint E80 Series belongs to an era built around bias-ply proportions and sidewall shape. Using the correct bias-ply sizing format helps preserve the tall, narrow stance and traditional visual balance that people expect from a late-1920s restoration.
Appearance is influenced by more than just the size stamped on the sidewall. The way the tire fills the wheel opening, the choice of blackwall or wide whitewall, and the overall tread style all contribute to whether the car looks authentically vintage or visually out of period for its age and design.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1927 Flint E80 Series?
Yes, modifications can affect tire fitment on a 1927 Flint E80 Series. Changes such as replacement wheels, altered wheel width, brake updates, suspension work, or body and fender adjustments can all change how a vintage bias-ply tire sits and clears the car.
A car of this age may have had many decades of repairs or restoration decisions, so it is smart to inspect the actual setup rather than relying only on model identification. Wheel measurements, clearance at full steering lock, and the relationship between tire profile and fender space should all be checked before installing replacements.
What should I inspect before driving a 1927 Flint E80 Series on new tires?
Before driving a 1927 Flint E80 Series on new tires, inspect the wheels, valve stems, mounting condition, and the vehicle's basic steering and suspension health. The tires themselves should be checked for correct seating, proper inflation, and any signs of shipping or installation damage before the car is put into service.
A short shakedown run should be followed by another look at pressure, wheel security, and any rubbing marks that suggest clearance issues. Vintage cars reward careful preparation, and catching a wheel, brake, or alignment problem early is especially important when the car is returning to road use after long storage.
How should 650-20 tires on a collector 1927 Flint E80 Series be maintained?
650-20 tires on a collector 1927 Flint E80 Series should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Look for cracking, cuts, bulges, uneven wear, and slow air loss, especially on a car that is driven only occasionally and may spend long periods parked indoors.
Collector vehicles often age tires out before they wear them out, so condition matters as much as tread depth. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the sidewalls, and periodic movement or careful storage practice can reduce flat-spotting during inactive periods.
