The 1927 Peerless 72 Series comes from the final years of one of America’s respected luxury marques, when large six-cylinder automobiles still relied on tall, narrow tires to deliver the stance and road presence buyers expected. For owners of this exact car, tire selection centers on two period bias-ply sizes, 33X6.00 and 600-21, both tied to a 21-inch wheel fitment. That makes the decision less about modern-style sizing and more about understanding which period size presentation suits the car and which sidewall treatment fits the desired look. For restoration-minded road use, wheel dimensions and overall visual proportion deserve as much attention as the tire itself.
Which Tire Size Is Right for The 1927 Peerless 72 Series
The 1927 Peerless 72 Series uses two primary tire sizes, both in bias-ply construction, and the first step is confirming which size is on the car now. Because both sizes are associated with the covered sub-model and one uses an older diameter-based format while the other uses a numeric bias-ply format on a 21-inch rim, the real decision is matching the vehicle’s wheel setup and the period look you want to maintain.
33X6.00 is an antique diameter-by-section size, meaning the first number refers to an approximate 33-inch overall tire diameter and the second number refers to an approximate 6.00-inch section width. It is a bias-ply fitment that reflects the older sizing conventions used on many premium cars of the late 1920s. This format is especially useful for owners focused on preserving the tall, upright tire profile that defines the visual character of a car like the 1927 Peerless 72 Series. Before choosing it, confirm that the car’s wheels and existing setup are intended for this style of period sizing.
600-21 is a numeric bias-ply size in which 600 represents a nominal 6.00-inch section width and 21 identifies the wheel diameter in inches. On the 1927 Peerless 72 Series, this size opens up the clearest product selection, including Lester and BFGoodrich offerings in blackwall and wide whitewall form through the Lester Classic Bias Ply and Silvertown Classic Bias Ply lines. That gives owners a meaningful choice between a more understated touring look and a more formal restoration-oriented whitewall presentation. Selection should still begin with wheel compatibility and the tire style that best matches the car’s intended appearance and use.
Sub-model fitment is straightforward here, as the covered 1927 Peerless 72 Series sub-model is associated with the same two bias-ply tire sizes. Even with that consistency, checking the exact wheel setup on the car still matters because pre-war vehicles are often restored or reconfigured over time.

1927 Peerless 72 Series 6 Cyl.
The 1927 Peerless 72 Series 6 Cyl. is associated with both 33X6.00 and 600-21 bias-ply tires, so the key question is which size convention matches the car’s current wheel and restoration setup. That means tire selection should focus on confirming wheel dimensions first, then choosing the period-style presentation and sidewall treatment that best suits the car.
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 1927 Peerless 72 Series?
The 1927 Peerless 72 Series is associated with two primary tire sizes: 33X6.00 and 600-21. Both are bias-ply fitments, and the covered 6-cylinder sub-model uses those same two sizes rather than a separate sub-model-specific tire.
That means the first task is identifying which size convention matches the wheels and setup on the car today. On an older luxury car that may have been restored long ago, it is wise to confirm the wheel diameter, existing tire markings, and overall visual proportion before choosing between the taller antique-style size format and the numeric 600-21 fitment.
What size rim does a 1927 Peerless 72 Series use?
The 1927 Peerless 72 Series uses a 21-inch rim with its 600-21 tire fitment. That 21-inch wheel diameter is the clearly stated rim size in the available fitment and product details for this vehicle.
Rim diameter is especially important on a late-1920s car because tire size markings can look unfamiliar compared with modern tires. Before choosing a replacement, inspect the wheel itself and confirm that the tire currently on the car matches the intended 21-inch setup, since collector vehicles are sometimes fitted with alternate wheels, older restorations, or mixed components over the years.
What does 33X6.00 mean on a 1927 Peerless 72 Series?
On a 1927 Peerless 72 Series, 33X6.00 is an antique diameter-by-section tire size. The 33 refers to the tire’s approximate overall diameter in inches, and the 6.00 refers to its approximate section width.
That sizing system predates the more familiar modern radial conventions, so it helps explain why this Peerless can show two different-looking period tire formats. Owners considering 33X6.00 should compare the existing wheel setup and the tire’s overall visual profile, since preserving the correct late-1920s stance is often just as important as simply matching a number molded into an old casing.
Choosing the Right Tire
What should I consider when choosing a 600-21 tire for a 1927 Peerless 72 Series?
Start with the correct size, construction, and wheel compatibility. For the 1927 Peerless 72 Series, 600-21 is a bias-ply fitment on a 21-inch rim, and available choices differ by brand, tire series, sidewall treatment, stated rim-width range, weight, and load information where those details are given.
The best selection approach is to match the tire to the car’s intended use and appearance. A blackwall can suit a more restrained touring presentation, while a wide whitewall creates a more formal restoration-oriented look. It also helps to compare the wheel width on the car with the rim-width specifications shown for applicable 600-21 products before making a final choice.
What sidewall styles are available for 1927 Peerless 72 Series tires?
For 600-21 tires on the 1927 Peerless 72 Series, available sidewall styles include blackwall and wide whitewall. Those choices give the car distinctly different visual presentations while staying within the same period bias-ply size family.
Sidewall selection is often one of the biggest appearance decisions on a pre-war car. A blackwall tends to look more restrained and utilitarian, while a wide whitewall gives the car a more formal, dressed appearance associated with many upscale vintage restorations. The choice should be guided by the vehicle’s restoration theme, surviving historical references, and the look you want when the car is on display or on tour.
What brands offer tires for the 1927 Peerless 72 Series?
The 600-21 tire size for the 1927 Peerless 72 Series is available from Lester and BFGoodrich. Those products appear in bias-ply construction and span the Lester Classic Bias Ply and Silvertown Classic Bias Ply series.
Brand choice should be treated as part of a broader comparison rather than the only decision. Once the correct size and wheel setup are confirmed, look at sidewall style, rim-width specification, weight, and any stated load information to decide which tire best fits the car’s intended appearance and use. On a collector vehicle, visual character can matter just as much as the brand name on the sidewall.
Restoration & Appearance
Which tire should I choose for a period-style 1927 Peerless 72 Series?
A period-style 1927 Peerless 72 Series tire choice starts with the two primary bias-ply sizes associated with the car: 33X6.00 and 600-21. Both reflect vintage sizing conventions, so the better choice depends on the wheel setup already on the car and the visual proportion you are trying to preserve.
For many restoration-minded owners, the decision goes beyond simple fitment and into presentation. The tall antique sizing language of 33X6.00 can appeal to buyers focused on early tire style, while 600-21 offers visible sidewall choices such as blackwall and wide whitewall. If exact originality matters, compare against marque literature, restoration photos, or other vehicle-specific historical references before final selection.
Does correct tire fitment matter for a 1927 Peerless 72 Series restoration?
Correct tire fitment matters greatly on a 1927 Peerless 72 Series restoration because tire height, width, and sidewall style strongly influence how a late-1920s luxury car sits and looks. On a vehicle from this era, the tires are a major part of the finished visual impression.
Getting the fitment right also helps avoid mismatched proportions that can make an otherwise strong restoration look off. Beyond appearance, proper sizing supports sensible wheel compatibility and road-use confidence. It is worth checking the wheel diameter, any rim-width guidance tied to the selected tire, and whether the car’s current setup reflects an older restoration that may not match the intended presentation today.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1927 Peerless 72 Series?
Yes. Modifications can affect tire fitment on a 1927 Peerless 72 Series, especially if the car has replacement wheels, altered suspension components, brake conversions, or body and fender work performed during an earlier restoration. Even on vintage cars, small changes in wheel setup can influence what tire size works best.
That is why the actual car should be checked rather than relying only on year and model. Confirm wheel diameter, wheel width, and the space available around the fenders and steering components before fitting replacement tires. On a pre-war car, long ownership histories often mean the present configuration may differ from how the vehicle was equipped decades earlier.
What should I inspect before driving a 1927 Peerless 72 Series on new tires?
Before driving a 1927 Peerless 72 Series on new tires, inspect the wheels for condition and correct sizing, verify that each tire is seated properly, and check inflation pressure carefully. It is also smart to look over valve stems, hardware, and the surrounding brake and suspension components while the wheels are off.
A short initial road test should include listening for rubbing, watching steering response, and rechecking air pressure afterward. Collector cars that sit for long periods also deserve a broader once-over, including wheel-bearing condition, alignment symptoms, and any signs that old components could affect tire wear. Early attention to those details helps the new tires work as intended.
How should 600-21 tires on a collector 1927 Peerless 72 Series be maintained?
600-21 tires on a collector 1927 Peerless 72 Series should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long exposure to heat, sunlight, and ozone sources during storage. Low annual mileage does not eliminate the need for inspection on an older collector car.
Maintenance also includes checking the car before each meaningful outing rather than assuming the tires are ready because the tread looks good. Vintage vehicles often sit long enough for pressure loss, flat spotting, or age-related deterioration to develop quietly. A careful pre-drive check of tire condition, wheel hardware, and general rolling-chassis health is part of responsible road use.
