The 1927 Chandler Special comes from the closing years of an independent American marque, when open-road touring still depended on tall, narrow tires and a distinctly prewar driving character. Buyers restoring or maintaining one of these cars usually want a tire that respects both its era and its chassis layout. This application uses bias-ply fitments, with 31X5.25 and 525-21 both tied to the Chandler Special 6 Cyl. configuration. Within the usable choices, sidewall appearance ranges from blackwall to wide whitewall, and the available tire series carry a traditional period-style presentation. The key is confirming which wheel setup is actually on the car before choosing a tire for restoration display or road use.
Which Tire Size Is Right for The 1927 Chandler Special
The 1927 Chandler Special uses two primary tire sizes, and the first step is confirming which wheel and rim-diameter setup is on the car. Both fitments are bias-ply, but they do not share the same rim diameter, so the real decision starts with wheel verification before moving on to sidewall style, tire series, and restoration priorities.
In a size like 31X5.25, the first number refers to the tire's approximate overall diameter in inches, while the second refers to its nominal section width. This is an older sizing convention associated with early automotive applications and it reflects the tall-tire proportions common in the period. For a 1927 Chandler Special, this size should be approached as a specialty antique fitment rather than a modern passenger-car format. The practical reason to focus on 31X5.25 is preserving the correct general tire profile for a car that still uses this early diameter-by-section wheel setup.
A size such as 525-21 uses a numeric bias-ply system, where 5.25 represents the nominal section width and 21 identifies the rim diameter in inches. On the 1927 Chandler Special, this keeps the tire in a traditional bias-ply construction that suits the vehicle's period look and wheel design. Available choices include Firestone and Excelsior lines, with blackwall and wide whitewall sidewall treatments for different restoration styles. This size is the one to evaluate when the car carries 21-inch wheels and the goal is a roadworthy vintage presentation with authentic-looking proportions.
The covered sub-model uses the same pair of bias-ply tire sizes, but fitment is still not a one-click decision because the two sizes rely on different rim diameters. Checking the exact wheel setup on the car matters before selecting a tire by style or series.

1927 Chandler Special 6 Cyl.
The 1927 Chandler Special 6 Cyl. is associated with both 31X5.25 and 525-21 bias-ply fitments, so wheel confirmation is the first priority. Once the rim setup is verified, tire selection becomes a matter of choosing the appropriate period-style format and sidewall appearance for the way the car is being restored or driven.
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 researching 1927 Chandler Special tires usually need to sort out size format, wheel diameter, bias-ply selection, period-style appearance, and the checks worth making before putting a prewar car back on the road.
Tire Size & Fitment
What tire size fits a 1927 Chandler Special?
The 1927 Chandler Special uses two primary tire sizes: 31X5.25 and 525-21. Both are bias-ply fitments, and the covered 1927 Chandler Special 6 Cyl. is associated with both sizes rather than one single modern-style replacement format.
The important distinction is that these two sizes do not use the same rim diameter. 31X5.25 is an older diameter-by-section format, while 525-21 is a numeric bias-ply size for a 21-inch rim. Before choosing a tire, inspect the wheels currently on the car and confirm which size system matches that setup.
What size rim does a 1927 Chandler Special use?
A 1927 Chandler Special can be associated with two different rim diameters depending on which tire size is on the car. The 31X5.25 fitment corresponds to a 5.0-inch rim diameter, while the 525-21 fitment uses a 21-inch rim diameter.
That makes wheel verification the most important fitment step before ordering tires. Antique cars are often restored, repaired, or reconfigured over time, so the tire size on paper is only part of the decision. Read the wheel and tire markings carefully and confirm the actual rim setup before moving to brand, sidewall style, or series choice.
What does 525-21 mean on a 1927 Chandler Special?
On a 1927 Chandler Special, 525-21 is a numeric bias-ply size. The 5.25 refers to the nominal section width in inches, and the 21 refers to the rim diameter in inches, using a sizing system common on vintage and prewar vehicles.
This matters because 525-21 is not the same kind of size designation as 31X5.25. It points you toward a 21-inch wheel and a more familiar vintage numeric fitment, which is where the available Firestone and Excelsior options appear. Once the wheel diameter is confirmed, sidewall style and tire series become easier to narrow down.
Choosing the Right Tire
What should I consider when choosing a 525-21 tire for a 1927 Chandler Special?
Start with the basics: confirm that the car actually uses the 525-21 size and that the wheel matches the tire's rim-diameter and rim-width requirements. From there, compare the available bias-ply choices by brand, tire series, sidewall style, load specification where stated, and the overall look you want on the car.
A Chandler restored for shows may call for a different presentation than one intended for casual touring. Firestone options include blackwall and wide whitewall versions in the Classic Bias Ply series, while Excelsior offers a blackwall Comp H choice. Matching the tire to the wheel, the vehicle's stance, and the restoration goal is more important than choosing by name alone.
What sidewall styles are available for 1927 Chandler Special tires?
For the 525-21 size used on the 1927 Chandler Special, available sidewall styles include blackwall and wide whitewall. Those two looks create very different visual impressions, even when the construction and general vintage character remain firmly in the bias-ply category.
Blackwall tires usually suit a more restrained, utilitarian presentation, while wide whitewalls create a more formal restoration-oriented look. Neither style should be treated as automatically correct for every surviving car, since many early vehicles have been restored in different ways over time. Choosing between them is largely about the appearance you want after fitment is confirmed.
What brands offer tires for the 1927 Chandler Special?
The 525-21 fitment for the 1927 Chandler Special is available from Firestone and Excelsior. Firestone appears in both blackwall and wide whitewall form within the Classic Bias Ply line, while Excelsior offers a blackwall option in the Comp H series.
That gives owners a useful range of traditional bias-ply choices without stepping outside the vintage character of the car. The smartest comparison is not simply brand against brand, but brand plus sidewall style, tire series, rim-width specification, and the way each choice supports the look and use of the Chandler once the wheel setup has been verified.
Restoration & Appearance
Which tire should I choose for a period-style 1927 Chandler Special?
A period-style 1927 Chandler Special should stay with the correct primary size and a bias-ply construction that matches the car's era. That means first confirming whether the car is set up for 31X5.25 or 525-21, then selecting a tire that preserves the tall, narrow vintage profile expected on a late-1920s automobile.
Appearance choices matter after size and wheel fitment are settled. In 525-21, blackwall and wide whitewall options create very different restoration outcomes, even though both keep the vehicle in an appropriate prewar tire style. When exact originality is especially important, marque references and period vehicle documentation are worth consulting before finalizing the sidewall treatment.
Does correct tire fitment matter for a 1927 Chandler Special restoration?
Correct tire fitment matters a great deal on a 1927 Chandler Special because the tire has a major effect on stance, wheel compatibility, and the overall period impression of the car. Using the wrong size format or the wrong rim diameter can change both the appearance and the practicality of the restoration.
Early cars depend heavily on tire proportions to look visually settled and mechanically appropriate. A restoration-minded owner should verify the actual wheel setup, confirm the matching size system, and then choose a sidewall style that fits the intended presentation. That approach keeps the tire decision aligned with the rest of the vehicle instead of treating it as an afterthought.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1927 Chandler Special?
Yes, modifications can affect tire fitment on a 1927 Chandler Special, especially on a car that may have seen wheel changes, restoration work, or chassis adjustments over many decades. Even when the correct vintage sizes are known, the actual wheels on the car may not match the original-style setup anymore.
A changed rim diameter, different wheel width, altered ride height, or body and fender work can all influence what clears properly. Antique vehicles often carry a long service history, so physical inspection matters as much as the size designation itself. Measure the wheels, inspect clearances at full steering lock, and confirm the tire matches the current configuration.
What should I inspect before driving a 1927 Chandler Special on new tires?
Before driving a 1927 Chandler Special on new tires, inspect the wheels, valve hardware, and the overall condition of the suspension and steering components. Tire pressure should be set correctly for the tire being used, and the wheels should be checked for condition, trueness, and secure mounting.
A prewar car also deserves a careful look at clearance around fenders, brake components, and steering movement once the new tires are installed. Drive quality on an antique chassis depends on more than the tire alone. A short, cautious test run can reveal rubbing, vibration, or seating issues before the car is taken on a longer outing.
How should 525-21 tires on a collector 1927 Chandler Special be maintained?
525-21 tires on a collector 1927 Chandler Special should be maintained with regular pressure checks, visual inspections, and careful storage habits. Watch for cracking, cuts, bulges, uneven wear, and any sign of air loss, especially on a vehicle that spends long periods parked between drives.
Collector cars often age their tires by time and environment as much as by mileage. Keeping the Chandler away from prolonged sunlight, moisture, excess heat, and ozone sources helps preserve the sidewalls and casing. It is also wise to inspect the tires before every road outing, since low-use vintage cars can develop condition issues quietly.
