The 1926 Peerless 67 Series comes from the final years when Peerless still stood among America’s established luxury marques, and tire choice plays a major role in preserving that stately pre-war character. These large, formal cars rely on bias-ply fitments, with 33X6.75 and 700-21 both associated with the 67 Series 8 Cyl. setup. That makes the key decision less about modernizing and more about confirming which wheel and tire arrangement is actually on the car. Within 700-21, there are meaningful differences in brand, tire series, and sidewall treatment, including blackwall and whitewall presentations. For restoration-minded ownership, careful wheel verification and period-appropriate appearance matter as much as the size itself.
Which Tire Size Is Right for The 1926 Peerless 67 Series
The 1926 Peerless 67 Series uses two primary tire sizes, and the first step is confirming which wheel setup is on the car. These are both bias-ply fitments, but they do not share the same rim diameter, so wheel measurement matters before any tire is selected. Once that is settled, the choice becomes one of correct period-style sizing and, where available, the preferred sidewall and tire series.
33X6.75 is an antique diameter-by-section size, meaning the first number refers to the tire’s approximate overall diameter of 33 inches and the second number refers to section width. It is a bias-ply fitment and represents the earlier sizing language often seen on substantial pre-war luxury and touring cars. For a 1926 Peerless 67 Series, this size points to a very specific wheel and tire arrangement, separate from the 21-inch numeric option used elsewhere on the same model family. Choosing it starts with confirming that the car actually carries the wheel setup intended for this size.
700-21 is a numeric bias-ply size in which the 700 denotes a nominal 7.00-inch section width class and the 21 identifies a 21-inch rim. This is a traditional bias-ply fitment well suited to the upright stance and road manners expected from a 1926 Peerless 67 Series. Available choices include Firestone, Michelin, Lester, and Excelsior, along with sidewall treatments such as blackwall, wide whitewall, and double-whitewall across several period-style series. It is the size with the broadest visible product selection, so appearance, rim-width compatibility, and intended use all become part of the decision.
Fitment for the covered 1926 Peerless 67 Series sub-model is straightforward in one sense and very important to verify in another. The 67 Series 8 Cyl. is associated with both primary tire sizes, so checking the actual wheel and rim arrangement on the car matters before choosing a replacement tire.

1926 Peerless 67 Series 8 Cyl.
The 1926 Peerless 67 Series 8 Cyl. uses bias-ply tires and is associated with both the 33X6.75 and 700-21 fitments. That makes wheel confirmation especially important, since the two sizes reflect different rim diameters and lead to different replacement paths.
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.

Available 700-21 choices span Firestone, Michelin, Lester, and Excelsior, with period-style series such as Firestone Balloon, Double Rivet, Lester Classic Bias Ply, and Comp H. The main differences in the product grid are sidewall treatment, rim-width specification, weight, and other bias-ply construction details.
Owners of a 1926 Peerless 67 Series usually need clarity on size selection, wheel confirmation, period-style tire appearance, and the condition checks that matter before putting a low-use collector car back on the road.
Tire Size & Fitment
What tire size fits a 1926 Peerless 67 Series?
The 1926 Peerless 67 Series is associated with two primary tire sizes: 33X6.75 and 700-21. Both are bias-ply fitments, and the covered sub-model, the 1926 Peerless 67 Series 8 Cyl., can appear with either size depending on the wheel setup on the car.
That means the right choice starts with the car itself rather than the model name alone. Measuring the wheel and confirming the rim diameter is essential, because 33X6.75 and 700-21 do not use the same rim. Once the wheel setup is confirmed, the next decision is whether the goal is a more understated blackwall look or a whitewall presentation within the available period-style options.
What size rim does a 1926 Peerless 67 Series use?
A 1926 Peerless 67 Series can use more than one rim diameter, depending on which primary tire size is on the car. The 33X6.75 fitment is associated with a 5.0-inch rim diameter, while the 700-21 fitment uses a 21-inch rim diameter.
Because those diameters are completely different, rim verification should happen before any replacement tire is selected. Collector cars of this age may have had wheel changes over the decades, and old size markings can be hard to read. Measuring the existing wheel and checking the tire size already mounted will usually settle the question faster than relying on assumption or appearance alone.
What does 33X6.75 mean on a 1926 Peerless 67 Series?
33X6.75 is an antique diameter-by-section tire size. In that format, 33 refers to the tire’s approximate overall diameter in inches, and 6.75 refers to its section width. On a 1926 Peerless 67 Series, it identifies a bias-ply fitment that uses a different wheel arrangement than the 700-21 numeric size.
This older sizing system can be unfamiliar because the first number is not the rim diameter. That is why it is important to confirm the actual wheel before ordering a replacement. On a restoration-oriented car, getting the size format right also helps preserve the proper visual proportion, especially on a large luxury automobile where tire height strongly affects overall stance.
Choosing the Right Tire
What should I consider when choosing a 700-21 tire for a 1926 Peerless 67 Series?
Start by confirming that the car actually uses the 700-21 wheel and tire setup, since the 1926 Peerless 67 Series is also associated with 33X6.75. Once 700-21 is confirmed, the main selection factors are brand, tire series, sidewall style, and wheel compatibility within the available bias-ply options.
The available 700-21 choices differ in presentation as much as in specification. A blackwall keeps the look restrained, while wide whitewall or double-whitewall options create a more formal period impression. Rim-width details also vary by product, so the exact wheel should be checked before choosing among Firestone Balloon, Michelin Double Rivet, Lester Classic Bias Ply, or Excelsior Comp H offerings.
What sidewall styles are available for 1926 Peerless 67 Series tires?
For the available 700-21 fitment, sidewall choices include blackwall, wide whitewall, and double-whitewall. Those options give a 1926 Peerless 67 Series owner room to tailor the car’s appearance from a more subdued touring look to a brighter restoration-oriented presentation.
Sidewall style should be chosen with the vehicle’s finish, trim level, and intended look in mind rather than by appearance alone. A whitewall can dramatically change how a large pre-war car sits visually, while a blackwall can feel more understated. If historical precision matters, compare the tire choice with period photos, marque references, or restoration documentation before settling on a final look.
What brands offer tires for the 1926 Peerless 67 Series?
In 700-21, the 1926 Peerless 67 Series has available tires from Firestone, Michelin, Lester, and Excelsior. Those choices appear across series such as Firestone Balloon, Double Rivet, Lester Classic Bias Ply, and Comp H, all within the period-style bias-ply category.
Brand alone should not be the only filter. The more useful comparison points are the series character, sidewall treatment, and whether the tire’s rim-width specification matches the wheel on the car. On a vehicle from this era, appearance and correct wheel relationship usually matter just as much as the brand name on the sidewall, especially if the car is being restored or shown.
Restoration & Appearance
Which tire should I choose for a period-style 1926 Peerless 67 Series?
A period-style 1926 Peerless 67 Series starts with using the correct primary size for the wheel setup actually on the car, either 33X6.75 or 700-21, and staying with bias-ply construction. That preserves the tire format and visual character that suit a large mid-1920s luxury automobile.
From there, the decision becomes more visual and use-based. In 700-21, available series and sidewall treatments allow a more formal whitewall presentation or a simpler blackwall look. For buyers pursuing exact historical accuracy, the final choice should be checked against period photos, marque references, and restoration records rather than assuming every period-style option represents the same original appearance.
How does tire construction affect the appearance of a restored 1926 Peerless 67 Series?
On a restored 1926 Peerless 67 Series, bias-ply construction is part of the vehicle’s traditional visual language. The tall profile, sidewall shape, and overall presentation of a bias-ply tire complement the upright proportions and formal stance expected on a luxury car from the mid-1920s.
Appearance is not just about whitewalls versus blackwalls. Construction affects how the tire fills the wheel opening and how authentic the finished car looks at a glance. That is why restoration-oriented buyers usually begin by preserving the proper size format and wheel relationship, then refine the look through sidewall treatment and series selection within the available bias-ply offerings.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1926 Peerless 67 Series?
Yes. Any change to wheels, hubs, suspension height, brake components, or body clearances can affect tire fitment on a 1926 Peerless 67 Series. That matters even more here because the car is associated with two very different primary sizes, 33X6.75 and 700-21, which do not share the same rim diameter.
A car that has been restored, updated, or assembled from long-stored parts should be checked carefully before replacement tires are chosen. Measure the wheel diameter, confirm the mounted tire size, and look at steering and fender clearance at full lock. On an older luxury car with tall tires and substantial bodywork, small setup differences can change fitment outcomes more than expected.
What should I inspect before driving a 1926 Peerless 67 Series on new tires?
Before road use, inspect the wheels, valve stems, wheel hardware, brake condition, steering components, and suspension for anything loose, worn, or damaged. The tires themselves should be checked for proper inflation, secure mounting, even seating on the rim, and clearances around fenders, suspension parts, and steering travel.
A 1926 Peerless 67 Series is a heavy pre-war car, so it is worth taking a slow, methodical approach before the first meaningful drive. Recheck inflation after the tires have settled, listen for rubbing at low speed, and watch for any pull or vibration. Even with newly mounted tires, the rest of the chassis still needs to be ready for safe road use.
How should tires on a collector 1926 Peerless 67 Series be maintained?
Collector-car tires on a 1926 Peerless 67 Series should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and air loss, and protected from long periods of heat, direct sunlight, and ozone exposure. Cars that are driven infrequently still need routine tire attention because age and storage conditions matter as much as mileage.
Regular visual checks are especially important on a pre-war vehicle that may spend long stretches parked. Move the car periodically to avoid prolonged static loading, keep the wheels clean and dry, and inspect the sidewalls before each drive. Any sign of deterioration, uneven wear, or repeated pressure loss is a reason to have the tires and wheels examined closely.
