Flint 80 Series Tires

Flint 80 Series is associated with two tire sizes for 1926: 32X6.20 and 650-20. The 32X6.20 size uses an older diameter-by-section format, while 650-20 is a numeric bias-ply size that clearly identifies a 20-inch rim. Available 650-20 products are built for 20-inch wheels, and that rim diameter is the key fitment point to verify on the car before moving further.

The practical approach is to inspect the wheels already on the car, then compare that information with any surviving factory literature, restoration records, or marque references. If the car has 20-inch rims, 650-20 is the clearly defined modern listing in this group, while 32X6.20 requires closer interpretation because the code's first number refers to tire diameter rather than wheel diameter.

On a Flint 80 Series, 32X6.20 is an antique diameter-by-section size. The 32 refers to the tire's approximate outside diameter in inches, and 6.20 refers to its section width. That first number is not the wheel diameter, which is why buyers familiar with later numeric or radial sizes often misread this style of code.

That older notation matters because you cannot assume rim size from the size code alone. When a Flint 80 Series carries an antique-format size, the next step is to verify the wheel itself and compare the car's equipment against restoration references so the finished tire dimensions and wheel diameter stay in the proper relationship.

A 1926 Flint 80 Series has 2 tire sizes listed because the model year is associated with two different sizing conventions: 32X6.20 and 650-20. That does not automatically mean every 1926 car used both interchangeably. It means a correct choice depends on the specific wheel and fitment configuration present on the individual car.

The important takeaway is that the year by itself is only the starting point. Check the installed wheel diameter, inspect any old tires or tubes still with the car, and use original service material or a knowledgeable Flint specialist to determine which of the two 1926 listings matches your particular Flint 80 Series.

Flint 80 Series fitments in this range are bias-ply types, and the listed 650-20 products fall into the kind of vintage construction that requires a tube. Antique-format and numeric bias-ply collector tires of this era are normally serviced as tube-type fitments rather than modern tubeless assemblies. That makes tube condition and correct sizing part of the overall tire decision, not an afterthought.

When refitting a Flint 80 Series, inspect the wheels carefully for rust, pitting, or damage that could affect tube life. Use tubes and flap components appropriate to the wheel and tire combination, and make sure the wheel is clean and properly prepared so the tube is not pinched, abraded, or stressed during mounting.

To confirm the correct tire size for a 1926 Flint 80 Series, start with the wheel diameter actually fitted to the car and compare it with the size notation on any surviving old tire, spare, owner's material, or restoration notes. The two listed sizes are 32X6.20 and 650-20, and they are written in different systems. One gives overall tire diameter and section width, while the other directly names a 20-inch rim.

That means a visual match alone is not enough. Measure the wheel, note any stamped markings, and then compare the result with trusted period references for your exact Flint 80 Series configuration. Doing that work first helps avoid choosing a tire that looks close on paper but is wrong in mounting diameter or overall proportions.

Flint 80 Series tires in the available 650-20 product range include both blackwall and wide whitewall sidewall styles. Blackwall appears across several passenger and truck-oriented options, while a 3.75-inch whitewall version is also offered. Those choices give a restorer room to match either a more utilitarian presentation or a dressier period look within the same basic size family.

The right sidewall style depends on how the Flint 80 Series is being restored and presented. A preservation-minded car should follow period photos, surviving evidence, or marque guidance, while a driver or personalized restoration may lean toward the sidewall treatment that best suits the car's stance and overall appearance.

Flint 80 Series tires in this product group are offered by Firestone, Denman, and Deka. Firestone appears in both passenger-car and truck-tread style 650-20 options, while Denman and Deka appear in truck-oriented 20-inch offerings. That gives the buyer a mix of traditional collector-car branding and heavier-duty style choices within the same listed size family.

Brand alone should not make the decision for a Flint 80 Series. Compare the size, sidewall style, tire series, and the way the car will actually be used, then choose the product that best matches the wheel, the era-correct look you want, and whether the car is being restored as a passenger automobile or set up with a more utility-focused tire style.

Flint 80 Series products in 650-20 include Firestone Classic Bias Ply, Highway Classic Truck, Deka Classic Truck, and Firestone Classic Truck series. Firestone Classic Bias Ply is the more traditional passenger-car style in this group, while the Highway Classic Truck, Deka Classic Truck, and Firestone Classic Truck lines are heavier-duty truck-oriented series. All are bias-ply, but they represent different visual and use-case directions.

For a Flint 80 Series restoration, the key question is whether the car should wear a passenger-car look or a more commercial-style tread and presentation. Matching the series to the vehicle's intended character matters almost as much as the size itself, because the tread style and sidewall treatment can significantly change how authentic or how utility-focused the finished car appears.

A Flint 80 Series should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, solvents, and electric motors. Bias-ply collector tires do best when protected from long static loading and environmental swings that harden rubber and stress the casing. Clean floors and stable temperature help preserve both the tire and the tube inside it.

If the Flint 80 Series will sit for extended periods, move it occasionally to change the contact patch or support it in a way that reduces continuous load on one spot. Keep inflation appropriate for storage, and inspect the sidewalls before the car goes back into service so age-related cracking or deformation is caught early.

Tires on a Flint 80 Series should be inspected before every drive and given a more thorough check at regular intervals even if the car sees only light collector use. Bias-ply tires on a 1920s automobile should be watched for cracking, weathering, casing distortion, uneven wear, tube-related issues, and any signs that the wheel itself may be affecting serviceability.

Frequent inspection matters because a Flint 80 Series is a low-use vintage car, and deterioration often comes from age and storage rather than mileage. Make tire inspection part of the same routine as checking wheel fasteners, steering play, brakes, and lubrication points so the car is evaluated as a complete operating system before road use.

Tires on a Flint 80 Series should be replaced when age, cracking, flat-spotting, sidewall weakness, casing damage, or tube-related trouble appears, even if the tread still looks serviceable. Collector tires do not age only by mileage, and a lightly driven 1920s car can sit long enough for the rubber and internal structure to become the real concern. Appearance alone is never a complete measure of roadworthiness.

That is especially important on a Flint 80 Series because period-style tires often live long, lightly used lives in storage. If an old tire's history is uncertain, have it evaluated by a specialist who understands vintage construction, and treat any aged assembly as a candidate for replacement before entrusting it to regular driving duty.

Flint 80 Series is associated here with two period size notations for 1926: 32X6.20 and 650-20. The available products identify modern replacement options in bias-ply form, including both passenger-car and truck-style series, but they do not tie a single original factory brand or exact assembly to every Flint 80 Series. That means original-equipment questions are best answered by combining the size listing with period Flint references for the individual car.

For restoration work, the key is to separate original size from modern replacement brand. Verify the wheel and size first, then use brochures, factory literature, club resources, and surviving examples to decide whether a blackwall or whitewall presentation and a passenger-car or truck-oriented series best reflects how your Flint 80 Series would have appeared when new.

Correct tire fitment can absolutely affect the value, credibility, and judging results of a Flint 80 Series restoration. Judges and experienced collectors notice whether the tire size, sidewall style, stance, and overall visual character suit the year and equipment of the car. A tire that is mechanically mountable but visually or proportionally wrong can distract from an otherwise careful restoration.

For that reason, Flint 80 Series owners should treat tires as part of the car's historical presentation rather than a final cosmetic add-on. Marque clubs, period photographs, and surviving unrestored examples can help settle whether the car should wear a blackwall or whitewall look and whether a more passenger-oriented or heavier-duty tread style belongs on the restoration.

Flint 80 Series tires in the available 650-20 range come in blackwall and wide whitewall form. Either style can be visually plausible on a mid-1920s car depending on presentation, trim, and the exact restoration goal, but they create very different finished impressions. Blackwalls usually read as more utilitarian, while a broad whitewall gives the car a more formal and upscale period appearance.

Choosing the correct sidewall for a Flint 80 Series restoration should come from the car's own evidence whenever possible. Study old photographs, sales literature, wheel covers, trim level clues, and prior restoration history, then select the sidewall style that supports the specific story your Flint 80 Series is meant to tell rather than choosing on appearance alone.

A properly selected, properly mounted, and well-maintained vintage-style bias-ply tire can be appropriate for limited public-road use on a Flint 80 Series, provided the rest of the car is equally sound. Tire safety on a 1926 automobile is inseparable from wheel condition, tubes, brakes, steering, bearings, and chassis setup. The tire itself is only one part of whether the car is truly ready to move under its own power.

Road use should reflect the capabilities of the entire Flint 80 Series rather than modern traffic assumptions. Keep speeds conservative, avoid harsh highway conditions, and inspect the car closely after periods of storage. A vintage car with fresh tires but neglected mechanical systems is still not a safe road car.

Before driving a Flint 80 Series, check tire inflation, sidewall condition, wheel security, and any sign of tube leakage or casing distortion. Then move outward to the rest of the car: steering response, brake operation, wheel bearings, suspension points, and fluid levels all matter on a 1920s machine. A careful pre-drive routine is part of safe operation, not optional preparation.

Because Flint 80 Series is a low-use collector automobile, issues often appear after storage rather than after high mileage. Roll the car slowly at first, listen for changes, and recheck the tires after the first short outing. That early inspection can reveal heat, shifting, or inflation problems before they become a larger failure on the road.

A Flint 80 Series should be driven at conservative speeds that respect both 1920s vehicle engineering and the limitations of vintage-style bias-ply tires. Even with newly manufactured collector tires, the handling, braking, and chassis behavior of a car from this era differ sharply from a modern automobile. Speed choice should reflect road surface, traffic density, weather, and the car's overall mechanical condition.

In practical terms, a Flint 80 Series is best enjoyed as a measured touring, show, and local-road car rather than a high-speed highway machine. Smooth inputs, moderate pace, and generous stopping distance will do more for safety and tire life than any single product choice, especially on narrow vintage tires and original-style wheels.
