The 1926 Davis 92 Series comes from the later brass-era to early vintage period, when tire construction, wheel design, and fitment details were still closely tied to the car's original mechanical layout. For owners of this unusual mid-1920s automobile, tire selection is less about modern upsizing and more about understanding the exact vintage sizing system the car uses. The 1926 Davis 92 Series is associated with two primary bias-ply sizes, 30X5.77 and 30x5, both tied to 7-inch wheel fitment. That makes the real choice one of correct vintage fitment style and wheel compatibility, especially for restoration-minded owners preparing the car for display or road use.
Which Tire Size Is Right for The 1926 Davis 92 Series
The 1926 Davis 92 Series uses two primary tire sizes, and the first step is confirming which wheel and tire style your car is set up to accept. Both are bias-ply fitments associated with a 7-inch rim, but they reflect different vintage sizing conventions, so the real decision is identifying the correct tire type for the car's present wheel configuration and restoration goals.
In a size like 30X5.77, the first number refers to the tire's approximate overall diameter in inches, while the second refers to its nominal section width. This is a bias-ply fitment with a 30-inch overall diameter and a section width around 5.7 inches, placing it squarely in an early vintage tire-sizing tradition. On a 1926 Davis 92 Series, this size is relevant when the car is using the wheel setup intended for this flotation-style dimension. Choosing it calls for careful confirmation of wheel type, rim fit, and the car's current restoration or operating configuration.
The 30x5 size also uses an antique diameter-by-section format, with 30 indicating approximate overall tire diameter and 5 indicating nominal section width in inches. This is a bias-ply fitment associated here with an antique inch, beaded-edge style presentation, which matters because vintage wheel and tire construction details can differ significantly from later drop-center setups. For a 1926 Davis 92 Series, this size suits owners focused on maintaining the proper early-style tire format. The important step is matching the tire to the actual wheel type on the car before moving forward.
Sub-model fitment is straightforward here because the covered 6 Cyl. configuration is associated with the same two primary tire sizes. Checking the exact sub-model still matters, but the larger question is confirming which of the two vintage tire formats matches the wheels currently on the car.

Frequently Asked Questions
Owners of a 1926 Davis 92 Series usually need clarity on vintage tire size meaning, 7-inch wheel fitment, restoration-minded construction choices, and the inspections that matter before returning an antique car to the road.
Tire Size & Fitment
What tire size fits a 1926 Davis 92 Series?
The 1926 Davis 92 Series is associated with two primary tire sizes: 30X5.77 and 30x5. Both are bias-ply fitments, and the covered 1926 Davis 92 Series 6 Cyl. sub-model can use either of these vintage sizes depending on the wheel and tire style the car is set up for.
That means the main task is not picking between modern alternatives but verifying which vintage format belongs on the actual wheels currently installed. On an antique vehicle, that check should include wheel type, rim design, and whether the car has remained original or has been altered during an earlier restoration.
What size rim does a 1926 Davis 92 Series use?
The 1926 Davis 92 Series is associated with a 7-inch rim diameter. That rim diameter is tied to the 30X5.77 fitment, and it is the critical wheel measurement to confirm before selecting a replacement tire for this car.
Rim diameter alone does not settle the whole fitment question on a mid-1920s vehicle, because wheel design and tire type can be just as important. A Davis that still uses its early-style wheel equipment should be checked carefully so the tire size and construction match the wheel's actual configuration rather than assumption.
What does 30x5 mean on a 1926 Davis 92 Series?
On a 1926 Davis 92 Series, 30x5 is an antique diameter-by-section tire size. The 30 refers to the tire's approximate overall diameter in inches, and the 5 refers to the nominal section width, also expressed in inches rather than a later alphanumeric or metric format.
That older sizing style matters because it points to a very different era of tire and wheel design than modern collector-car fitments. Anyone selecting a 30x5 tire should confirm the car's wheel type and whether the restoration is intended to preserve an early beaded-edge style presentation or another correct vintage setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 1926 Davis 92 Series?
Start with the exact size and vintage format your 1926 Davis 92 Series requires, since this car is associated with both 30X5.77 and 30x5 bias-ply tires. Those sizes are not just different labels for the same modern fitment approach; they reflect distinct early tire conventions that need to match the wheel setup.
After confirming size, think about how the car will be used. A display-focused restoration may emphasize period-style appearance, while a car prepared for regular antique touring still needs the correct construction, sound wheel condition, and enough clearance for safe operation without guessing across early tire systems.
How do I choose between the available 30X5.77 and 30x5 tires for a 1926 Davis 92 Series?
The right choice depends on which size matches the wheel and tire system on the car. A 1926 Davis 92 Series can be associated with either 30X5.77 or 30x5, so the decision is based on authentic fitment needs rather than simple preference between two interchangeable modern sizes.
The most useful comparison is not just overall diameter, since both are 30-inch class sizes, but how the tire is built and intended to seat on the wheel. Checking the wheel design, the car's restoration history, and any previous changes made over the years will usually point to the proper direction.
What rim-fitment details matter when choosing 1926 Davis 92 Series tires?
Rim diameter is the first checkpoint, and the 1926 Davis 92 Series is associated with a 7-inch rim diameter. Beyond that, antique vehicles often require closer attention to the actual wheel design, because early tire styles can depend on details that are more specialized than later collector-car applications.
A buyer should confirm that the wheel matches the intended tire format before focusing on appearance or road use. It is also wise to inspect for bent rims, corrosion, worn wheel hardware, and signs that the car may have been converted to a different wheel arrangement during its lifetime.
Restoration & Appearance
Which tire should I choose for a period-style 1926 Davis 92 Series?
A period-style 1926 Davis 92 Series tire choice starts with using the correct vintage size format for the car's wheel setup, either 30X5.77 or 30x5, both in bias-ply construction. On a vehicle from this era, the proper tire look is tied closely to the underlying wheel and fitment system, not just sidewall appearance.
That makes authenticity a matter of matching the tire to the car's actual configuration and restoration objective. Owners pursuing a highly accurate presentation should compare the car against marque literature, period photos, or trusted antique-vehicle references before settling on one of the two primary size conventions.
Does correct tire fitment matter for a 1926 Davis 92 Series restoration?
Correct tire fitment matters a great deal on a 1926 Davis 92 Series because the car comes from an era when wheel and tire systems were far less standardized than later collector vehicles. Choosing between 30X5.77 and 30x5 affects not only appearance, but also whether the tire properly matches the wheel arrangement on the car.
A restoration can look convincing at a glance and still use the wrong tire format underneath. Getting the fitment right helps preserve the car's stance, visual proportion, and mechanical compatibility, which is especially important when the vehicle will do more than sit on display at occasional antique events.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1926 Davis 92 Series?
Yes, modifications can affect tire fitment on a 1926 Davis 92 Series, especially if the car has had wheel changes, brake updates, suspension work, or a prior conversion away from its original early wheel arrangement. On an antique vehicle, even seemingly minor changes can alter which vintage tire size and style should be used.
That is why a visual inspection of the wheels and surrounding clearances is important before choosing between 30X5.77 and 30x5. A Davis with altered hardware, replacement rims, or body and suspension changes should be checked carefully so the selected tire suits the car as it exists today.
What should I inspect before driving a 1926 Davis 92 Series on new tires?
Before driving a 1926 Davis 92 Series on new tires, inspect the wheels, valve hardware, and the tire seating surfaces for age, wear, rust, or damage. It is also important to confirm that the tires are mounted to the correct wheel type and that there is no interference at the fenders, suspension, or steering components.
An antique car deserves a broader road-use check than tires alone. Look at wheel fasteners, bearings, steering play, brake function, and inflation condition before heading out, especially if the car has been stored for long periods or has only seen occasional low-speed show and parade use.
How should tires on a collector 1926 Davis 92 Series be maintained?
Tires on a collector 1926 Davis 92 Series should be kept properly inflated, inspected regularly, and protected from long exposure to sunlight, moisture, and ozone-producing equipment. Even when tread looks acceptable, antique and collector vehicles can spend enough time parked that age, drying, and flat-spotting become more important than mileage.
Regular walk-around checks help catch sidewall cracking, cuts, bulges, or slow air loss before they become bigger problems. A car that is driven only occasionally also benefits from clean storage conditions and periodic movement, since long stationary periods can be harder on vintage-type tires than light seasonal use.
