The 1926 Apperson 6 Cyl. comes from the final years of an independent American luxury marque that built its reputation on substantial touring cars and a distinct pre-war road presence. For owners of one of these surviving cars, tire choice is as much about preserving the vehicle’s stance and character as it is about basic fitment. This Apperson uses bias-ply fitments in 33X6.00 and 600-21, both tied to a 21-inch wheel application. Available choices center on traditional bias-ply construction, with blackwall and wide whitewall presentations offered in 600-21. The key is confirming which size is on the car now and matching that choice to restoration goals and safe road use.
Which Tire Size Is Right for The 1926 Apperson 6 Cyl.
The 1926 Apperson 6 Cyl. uses two primary tire sizes, both in bias-ply construction, and both relate to a 21-inch wheel application. The first step is identifying which size is actually mounted on the car, since pre-war vehicles are often restored, re-bodied, or fitted with wheels and tires that differ from what another example may use.
A 33X6.00 size uses an older diameter-by-section format, where the first number refers to the tire’s approximate overall diameter and the second refers to section width in inches. On the 1926 Apperson 6 Cyl., this is a bias-ply fitment that suits the car’s pre-war proportions and traditional tire profile. Selection within this size should focus on preserving the correct look and verifying wheel compatibility, since this format is very different from later numeric sizing. It is the right size to evaluate only if the car is already set up for this larger-diameter antique-style fitment.
A 600-21 tire is a vintage numeric bias-ply size, with 6.00 indicating nominal section width in inches and 21 identifying the rim diameter. For the 1926 Apperson 6 Cyl., this size offers the clearest product selection, including Lester and BFGoodrich options, along with blackwall and wide whitewall sidewall treatments in the Lester Classic Bias Ply and Silvertown Classic Bias Ply series. This size makes sense for owners who want a traditional pre-war presentation while still having meaningful choice in brand, sidewall style, and rim-width specification.
Fitment is straightforward here because the covered sub-model shares the same pair of primary tire sizes. Checking the exact sub-model still matters, but the main task is confirming which of the two sizes is actually on the car and whether the wheel setup matches it.

1926 Apperson 6 Cyl. Base
The 1926 Apperson 6 Cyl. Base uses the same two bias-ply tire sizes associated with this model family, so the fitment question is not trim-specific. Tire selection comes down to confirming whether the car is wearing 33X6.00 or 600-21 and then choosing the sidewall style and product series that best suit the restoration and road-use plan.
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.

Tire Size & Fitment
What tire size fits a 1926 Apperson 6 Cyl.?
The 1926 Apperson 6 Cyl. uses two primary bias-ply tire sizes: 33X6.00 and 600-21. Those sizes are not interchangeable by name alone, even though both belong to the same vehicle family and relate to a 21-inch wheel application.
The practical step is to inspect the tires and wheels currently on the car before choosing a replacement. A pre-war vehicle may have been restored or changed over time, so the correct purchase depends on matching the existing wheel setup, confirming the size stamped on the tire, and making sure the replacement preserves proper clearance and overall presentation.
What size rim does a 1926 Apperson 6 Cyl. use?
The 1926 Apperson 6 Cyl. uses a 21-inch rim application. That rim diameter is directly tied to the 600-21 size, and the vehicle’s overall fitment centers on 21-inch wheel use.
Rim diameter is only one part of the fitment picture on a car of this age. It is still important to verify the actual wheel on the vehicle, especially if the car has had restoration work, replacement wheels, or long-term ownership changes. On 600-21 products, rim-width details can also matter, so both diameter and wheel width deserve a close look before replacing tires.
What does 600-21 mean on a 1926 Apperson 6 Cyl.?
A 600-21 tire uses a vintage numeric bias-ply size format. The 6.00 refers to the nominal section width in inches, while 21 refers to the wheel diameter in inches.
That older size format helps explain why a 600-21 should be matched carefully rather than compared casually to later metric or passenger-car sizing. On a 1926 Apperson 6 Cyl., choosing within 600-21 is more about sidewall style, brand, and wheel compatibility than learning a modern aspect-ratio system. It is a traditional pre-war fitment, so preserving the right stance and visual balance matters as much as the numbers themselves.
Choosing the Right Tire
What should I consider when choosing a 600-21 tire for a 1926 Apperson 6 Cyl.?
Start with the basics: confirm that the car actually uses 600-21 rather than 33X6.00, and make sure the wheel is a 21-inch application suited to the tire. From there, the meaningful differences are brand, tire series, sidewall style, and any stated rim-width or load details.
For this Apperson, the visual effect matters because the tire contributes heavily to the car’s overall stance. A blackwall gives a more restrained presentation, while a wide whitewall creates a more formal period-style look. If the car is driven regularly, inspect wheel condition and compare the tire’s intended fitment to the vehicle’s current setup instead of assuming all vintage 21-inch tires behave the same.
What sidewall styles are available for 1926 Apperson 6 Cyl. tires?
Within the available 600-21 options for the 1926 Apperson 6 Cyl., sidewall styles include blackwall and wide whitewall. Those choices change the car’s appearance noticeably even when the tire size remains the same.
The best sidewall style depends on how the car is being presented. A blackwall generally suits a simpler touring look, while a wide whitewall tends to emphasize a more formal restoration-oriented appearance. Sidewall choice should come after confirming the correct size and wheel setup, since the visual finish only matters once the underlying fitment is right for the vehicle.
What brands offer tires for the 1926 Apperson 6 Cyl.?
Available 600-21 tires for the 1926 Apperson 6 Cyl. include options from Lester and BFGoodrich. Those products appear in the Lester Classic Bias Ply and Silvertown Classic Bias Ply series, both in traditional bias-ply construction.
Brand choice should be treated as one part of a broader comparison rather than the only decision. It makes sense to compare sidewall presentation, wheel-width suitability where stated, and whether the tire’s overall look fits the car’s restoration plan. On a pre-war Apperson, the tire has a major influence on appearance, so visual character can matter almost as much as the name on the sidewall.
Restoration & Appearance
Which tire should I choose for a period-style 1926 Apperson 6 Cyl.?
A period-style approach for a 1926 Apperson 6 Cyl. starts with staying in one of its correct bias-ply primary sizes, either 33X6.00 or 600-21 depending on the wheel and tire setup already on the car. That keeps the selection grounded in the tire formats the vehicle actually uses.
Once the correct size is confirmed, appearance becomes the next decision. In 600-21, blackwall and wide whitewall choices create very different visual results, yet both remain traditional in character. Owners pursuing exact historical detail should compare the finished look against marque references, period photos, or restoration documentation rather than assuming a particular sidewall treatment was universal across every surviving Apperson.
Does correct tire fitment matter for a 1926 Apperson 6 Cyl. restoration?
Correct tire fitment matters a great deal on a 1926 Apperson 6 Cyl. because tire height, width, and construction shape the car’s stance more dramatically than on many later vehicles. The wrong size can change the visual balance even before any road-use concerns appear.
A careful restoration should treat tires as part of the overall presentation, not just a replaceable service item. Confirming whether the car belongs on 33X6.00 or 600-21 helps preserve the intended look, and choosing between blackwall and wide whitewall refines that result. Proper fitment also supports practical checks such as wheel compatibility and clearance before the car returns to regular driving.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1926 Apperson 6 Cyl.?
Yes, modifications can affect tire fitment on a 1926 Apperson 6 Cyl. even when the car still appears mostly original. Replacement wheels, brake work, suspension repairs, or body and fender changes can alter the amount of space available for a vintage bias-ply tire.
That is why the existing car should be inspected before choosing between 33X6.00 and 600-21. A vehicle from this era may have seen many decades of changes, and even small wheel differences can matter. It is wise to measure the current wheel diameter and width, then check steering and fender clearance with the tire size already on the car as a reference point.
What should I inspect before driving a 1926 Apperson 6 Cyl. on new tires?
Before road use, inspect the wheels, valve stems, mounting hardware, and the overall condition of the suspension and steering components. The tires themselves should be checked for proper inflation, even bead seating, and any signs of shipping or installation damage before the car is driven any distance.
A pre-war collector car also benefits from a slow visual check after the first short drive. Look for rubbing marks, uneven stance, air loss, or signs that the tire is contacting fenders or suspension parts during turns. Since the 1926 Apperson 6 Cyl. uses vintage bias-ply sizing, early inspection helps catch setup issues before they turn into tire wear or road-use problems.
How should 600-21 tires on a collector 1926 Apperson 6 Cyl. be maintained?
600-21 tires on a collector 1926 Apperson 6 Cyl. should be maintained with regular pressure checks, routine visual inspections, and clean storage conditions. Even on a low-mileage car, age, heat, sunlight, and long stationary periods can affect tire condition long before tread wear becomes the main concern.
A good maintenance routine includes looking for sidewall cracking, cuts, bulges, flat-spotting, and slow air loss before each outing. The car should be stored away from prolonged moisture and ozone sources when possible, and the tires deserve another inspection after longer drives. Collector vehicles often sit for extended periods, so tire condition should be judged by age and appearance, not mileage alone.
