The 1926 Flint Jr comes from an era when independent automobile makers competed on style, value, and mechanical simplicity, and tire fitment was still closely tied to the character of the chassis itself. For owners of a surviving Flint Jr today, the tire decision is as much about authenticity of presentation as it is about basic road readiness. This model uses bias-ply fitments, with 30X5.25 and 5.25-20 both associated with the 1926 Flint Jr 6 Cyl. That means the key question is confirming which wheel setup is actually on the car, then choosing a tire that suits restoration goals, safe clearance, and intended driving use.
Which Tire Size Is Right for The 1926 Flint Jr
The 1926 Flint Jr uses two primary tire sizes, and the first step is confirming which wheel and rim diameter the car actually has. Both fitments are bias-ply, but they are not the same size format, so identifying the exact wheel setup on the 1926 Flint Jr 6 Cyl. matters before comparing tire appearance, dimensions, or restoration-oriented choices.
30X5.25 is an antique diameter-by-section size, meaning the first number refers to the tire's approximate overall diameter and the second refers to its section width. On the 1926 Flint Jr, this is a bias-ply fitment that reflects early automotive sizing practice rather than later rim-first numeric sizing. That makes it especially relevant for owners trying to preserve a distinctly pre-war visual character. Choosing this size starts with verifying that the car is using the wheel setup intended for this fitment, since antique size formats do not translate cleanly into later numeric tire conventions.
5.25-20 is a numeric bias-ply size in which 5.25 indicates the nominal section width in inches and 20 identifies the rim diameter. For a 1926 Flint Jr, this format represents a more familiar vintage bias-ply sizing convention and remains fully in keeping with the period character of the car. It is a useful fitment for owners focused on correct-size vintage presentation and traditional construction. Before selecting it, confirm that the wheel diameter matches this size and that the car has not been changed to a different wheel arrangement during earlier restoration work.
Tire fitment for the covered 1926 Flint Jr sub-model is straightforward in one sense and still worth checking in another. The 6 Cyl. is associated with both primary tire sizes, so the real task is confirming which wheel setup is on the car before choosing a replacement tire.

The 1926 Flint Jr 6 Cyl. is associated with both 30X5.25 and 5.25-20 bias-ply fitments, so tire selection begins with the wheels rather than the sub-model name alone. Once the installed rim setup is confirmed, the choice becomes one of proper vintage sizing, period-style appearance, and road-use suitability.
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.
Frequently Asked Questions
Owners of a 1926 Flint Jr usually need to sort out size format, wheel diameter, and period-style bias-ply fitment before anything else. These questions focus on selecting between 30X5.25 and 5.25-20, protecting restoration appearance, and checking the car carefully before road use.
Tire Size & Fitment
What tire size fits a 1926 Flint Jr?
The 1926 Flint Jr is associated with two primary bias-ply tire sizes: 30X5.25 and 5.25-20. Both are tied to the 1926 Flint Jr 6 Cyl., so the car does not point to just one universal replacement size without first confirming which wheel setup is actually installed.
That matters because these two sizes use different sizing conventions and different rim diameters. A buyer should inspect the wheels already on the car, confirm the rim diameter, and then choose the tire size that matches that setup rather than assuming one vintage size automatically substitutes for the other.
What size rim does a 1926 Flint Jr use?
The 1926 Flint Jr is associated with two rim diameters through its primary tire fitments. The 30X5.25 fitment is paired with a 5.0-inch rim diameter, while the 5.25-20 fitment uses a 20-inch rim diameter.
Because those rim diameters are very different, checking the actual wheels on the car is the most important first step before ordering tires. On an older vehicle that may have been restored or modified decades ago, the installed wheel setup should always be verified directly instead of relying only on the vehicle name.
What does 30X5.25 mean on a 1926 Flint Jr?
30X5.25 is an antique diameter-by-section tire size. In that format, 30 refers to the approximate overall tire diameter and 5.25 refers to the section width, rather than using the later rim-first numbering seen in sizes such as 5.25-20.
That distinction is important on a 1926 Flint Jr because antique tire markings can be unfamiliar to modern buyers and do not translate neatly into later sizing systems. The practical takeaway is to match the tire to the actual wheel arrangement on the car and avoid assuming that a similar-looking vintage number means the same thing.
Choosing the Right Tire
What should I consider when choosing a tire for a 1926 Flint Jr?
Start with the exact tire size and wheel diameter already on the car. A 1926 Flint Jr can use either 30X5.25 or 5.25-20, and both are bias-ply fitments, so the first decision is confirming which of those two vintage setups applies to the vehicle in front of you.
After that, think about how the car will be used and presented. A preservation-minded car may call for the size that best matches its current restoration, while a car intended for occasional road driving still needs proper wheel match, adequate clearance, and a careful check of tire age, condition, and overall chassis readiness.
How do I choose between 30X5.25 and 5.25-20 tires for a 1926 Flint Jr?
Choose between 30X5.25 and 5.25-20 by matching the tire to the wheel setup on the car, not by preference alone. The 1926 Flint Jr 6 Cyl. is associated with both sizes, but they are different fitments and should be treated as separate choices rather than interchangeable labels.
A close wheel inspection is the safest way to make that decision. Confirm the rim diameter, look for any signs that the car was changed during an earlier restoration, and compare the existing tire markings if they are still readable. Once the wheel setup is confirmed, selecting the proper period-style bias-ply size becomes much more straightforward.
Why does the 1926 Flint Jr have more than one tire size?
The 1926 Flint Jr has more than one tire size because both 30X5.25 and 5.25-20 are associated with this model, even within the 6 Cyl. sub-model. On a vehicle from this era, that usually means the tire decision cannot be made from the year, make, and model alone.
For today's owner, that means the car itself has to settle the question. Vintage vehicles often pass through long restoration histories, and wheels can change over time. Verifying the actual rim diameter and installed setup prevents ordering a tire that matches the model name on paper but not the wheels currently on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1926 Flint Jr?
A period-style 1926 Flint Jr should stay with the bias-ply construction associated with the car and use the exact primary size that matches its wheel setup, either 30X5.25 or 5.25-20. Both sizes support a traditional pre-war presentation in a way that suits the vehicle's age and character.
The better choice depends on what is physically on the car now and how closely the restoration follows its earlier configuration. When exact originality matters, compare the wheels and surviving historical references for the specific vehicle. For most restorations, proper vintage sizing and correct wheel match are the foundation of an authentic-looking result.
Does correct tire fitment matter for a 1926 Flint Jr restoration?
Correct tire fitment matters a great deal on a 1926 Flint Jr restoration because the tire makes up a large visual part of the car's stance and period presence. Using the right bias-ply size for the installed wheels helps preserve the proportions that suit a mid-1920s automobile.
The effect is practical as well as visual. A mismatched size can create problems with wheel compatibility, clearance, and overall presentation even before the car is driven. Careful restorers usually confirm the wheel diameter first, then select the vintage tire size that supports both the car's appearance and basic roadworthiness.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1926 Flint Jr?
Yes, modifications can affect tire fitment on a 1926 Flint Jr, especially because this model is already associated with two different primary tire sizes. Wheel changes, brake conversions, suspension work, or earlier restoration substitutions can all alter what the car will actually accept today.
That is why a hands-on inspection matters more than assumptions. Check the installed rim diameter, wheel condition, and available clearance around fenders and steering components before choosing tires. On a car of this age, even a long-ago change can influence fitment, so the current physical setup should guide the final decision.
What should I inspect before driving a 1926 Flint Jr on new tires?
Before driving a 1926 Flint Jr on new tires, inspect the wheels for damage or distortion and make sure the tire size matches the actual rim setup. The suspension, steering linkage, and brake components should also be checked so the car is ready to use the new tires safely.
A roadworthy vintage tire installation also depends on basic condition checks. Look over tread and sidewalls for damage after mounting, verify air pressure, and make sure there is no rubbing at full steering travel. A short, careful test drive is a smart final step before taking the car on a longer outing.
How should tires on a collector 1926 Flint Jr be maintained?
Tires on a collector 1926 Flint Jr should be maintained with regular pressure checks, periodic visual inspections, and careful storage habits. Even on a car that is driven only occasionally, the tires should be checked for cracking, cuts, bulges, uneven wear, and any signs of air loss before use.
Collector vehicles benefit from storage away from prolonged sunlight, heat, moisture, and ozone sources such as electric motors or generators. It also helps to move the car periodically so it does not sit in one position for too long. Low annual mileage does not prevent aging, so condition matters as much as tread depth.
