Peerless 67 Series Tires

The Peerless 67 Series uses two listed sizes for 1926: 33X6.75 and 700-21. The important distinction is that 33X6.75 is an antique diameter-by-section size, while 700-21 is a numeric balloon bias-ply size built for a 21-inch rim. Current products are listed in 700-21, all as bias-ply tires for 21-inch wheels, with several sidewall styles available.

Choosing correctly starts with the wheel and tire type already on the car, not just the model year. A Peerless 67 Series that has been restored or altered over the years may no longer match its original wheel setup, so measure the rim, read any existing sidewall markings carefully, and compare the overall profile before replacing anything.

On a Peerless 67 Series, 33X6.75 is an antique size format rather than a modern wheel-and-section code. The 33 refers to the tire's approximate outside diameter in inches, and 6.75 refers to section width. It does not tell you the wheel diameter, which is why this style of marking can be misleading to modern buyers who expect the last number to be the rim size.

That difference matters because a buyer can easily mistake 33X6.75 for a wheel measurement when it is really an overall tire diameter. The right approach is to inspect the wheel itself and compare the car's setup to period-correct tire proportions so the replacement keeps the proper stance, clearance, and appearance for a 1926 Peerless 67 Series.

The Peerless 67 Series appears with both an antique size and a 21-inch balloon size, so rim diameter cannot be assumed from every code. The 700-21 products are built for 21-inch rims, while 33X6.75 does not include rim diameter in the size marking at all. That means two different reading methods are involved even within the same 1926 model listing.

The practical takeaway is to verify the wheel before you select a tire. If the car is already wearing balloon tires, the 21-inch rim dimension is straightforward; if it is using the older diameter-by-section format, the wheel size has to be confirmed separately so the replacement tire matches the actual rim and not just the visual height of the car.

The listed Peerless 67 Series products are bias-ply tires, and the size formats involved are period styles that normally use tubes. The 700-21 offerings are all bias-ply, and antique diameter-by-section fitments such as 33X6.75 also belong to the tube-type era. For a 1926 luxury car like the Peerless 67 Series, tube fitment is part of the expected construction approach.

Tube selection should match both the tire size and the rim condition, especially on older wheels that may have seen decades of use, storage, or restoration work. It is also wise to inspect the rim strip, valve hole, and bead seat before mounting, because tube life on a collector car depends as much on wheel condition as on the new tire itself.

A 1926 Peerless 67 Series can point you to either 33X6.75 or 700-21, so the best first check is the wheel and the type of tire already fitted. If the car uses balloon tires on 21-inch rims, 700-21 is the matching listed size with available products. If the car is set up around the older diameter-by-section format, 33X6.75 is the size to investigate further.

Start with the actual rim diameter, then compare the sidewall markings and overall tire profile to period photographs or original paperwork for the specific car. That is especially important on long-restored automobiles, where wheel swaps and later conversions are common and can make the model year alone an unreliable guide.

Peerless 67 Series tires in the available 700-21 products come in several sidewall styles, including blackwall, wide whitewall, and double-whitewall. Those choices appear across brands such as Firestone and Lester, while other 700-21 offerings are blackwall-only. The sidewall treatment changes the visual character of the car more than many buyers expect.

A blackwall usually suits a restrained, formal pre-war appearance, while whitewall treatments create a more dressed presentation that many owners prefer on large luxury cars. If originality matters for a Peerless 67 Series restoration, compare the sidewall style to period photos, surviving cars, and marque references rather than choosing only by modern taste.

The listed Peerless 67 Series tire products include Firestone, Michelin, Lester, and Excelsior in size 700-21. Those brands cover several series, including Firestone Balloon, Michelin Double Rivet, Lester Classic Bias Ply, and Excelsior Comp H. All of the currently listed products for this model page are bias-ply offerings.

Brand choice often comes down to the look and period character you want as much as the size itself. Some owners lean toward a particular tread or sidewall presentation, while others are trying to match a specific restoration style, so it helps to decide whether appearance, touring use, or show presentation is the main goal for the Peerless 67 Series.

The Peerless 67 Series products listed in 700-21 include Firestone Balloon, Michelin Double Rivet, Lester Classic Bias Ply, and Excelsior Comp H. These series represent different period-style bias-ply offerings rather than a mix of modern radial and vintage construction. Their differences are chiefly in brand family, tread and presentation style, and sidewall options such as blackwall or whitewall treatments.

For a buyer, the series name helps narrow the look and character of the finished car once the size is settled. A large pre-war automobile like the Peerless 67 Series can wear very differently depending on whether you want a simple blackwall touring appearance or a more formal whitewall presentation that better complements a concours-oriented restoration.

A Peerless 67 Series should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, ozone sources, and standing moisture. Proper inflation matters even when the car is not being driven, because underinflated bias-ply tires can develop flat spotting or sidewall stress during long storage. Clean floors and stable temperatures also help preserve rubber and tube life.

If the Peerless 67 Series will sit for extended periods, move it slightly from time to time or support it in a way that reduces continuous load on one contact patch. Collector cars benefit from regular visual checks during storage, since age, tube seepage, and rim issues often reveal themselves long before a tire shows meaningful tread wear.

Tires on a Peerless 67 Series should be inspected before every meaningful drive and more thoroughly at regular intervals throughout the season. On a pre-war collector car, inspection means more than checking tread: look for sidewall cracking, bead movement, uneven shape, tube-related pressure loss, and any signs that an older wheel is chafing or damaging the tire from inside.

A close inspection routine is especially important because a Peerless 67 Series is likely driven infrequently, and long periods of sitting can hide problems until the car is back on the road. Many owners make inspection part of the same routine as checking fluids, wheel fasteners, brakes, and steering before an event, tour, or parade.

A Peerless 67 Series tire should be replaced when age, cracking, hardening, separation, chronic air loss, or visible structural change appears, even if the tread still looks usable. Collector tires often age out before they wear out, particularly on low-mileage pre-war cars. Serviceability depends on condition, storage history, and inspection results rather than remaining tread depth alone.

That is particularly true on a heavy luxury automobile such as the Peerless 67 Series, where load, heat, and time can work against an older casing. If a period tire or long-stored tire is under consideration, a specialist inspection is the sensible step before any road use, because appearance alone is not a reliable measure of safety.

The Peerless 67 Series is associated here with both 33X6.75 and 700-21, which reflects the period overlap between older diameter-by-section sizing and newer balloon-type fitments. The available product families for 700-21 include Firestone Balloon, Michelin Double Rivet, Lester Classic Bias Ply, and Excelsior Comp H. That tells you the car belongs to a transitional tire era rather than a single modern-style standard.

For a precise restoration, the best reference is the specific car's original literature, surviving wheel setup, and Peerless marque knowledge. Large luxury cars from the 1920s were often preserved, updated, or restored more than once, so confirming the exact period-correct tire type for your own Peerless 67 Series is worth the extra effort.

Correct tire fitment absolutely affects how a Peerless 67 Series is perceived in restoration and judging circles. Size, profile, sidewall treatment, and overall period appropriateness all influence whether the car looks authentically proportioned. On an upscale 1926 automobile, the tire is a prominent visual element, so an incorrect stance or obviously mismatched style can undermine an otherwise careful restoration.

That does not always mean there is only one acceptable presentation, but it does mean the choice should suit the era and the specific car. Owners concerned with concours standards or market value should compare their Peerless 67 Series against period photos, club guidance, and the wheel setup actually fitted to the car before finalizing a tire choice.

Peerless 67 Series tires in 700-21 are available with blackwall, wide whitewall, and double-whitewall sidewall styles. Any of those can create a convincing period presentation depending on the restoration direction, since pre-war luxury cars often varied in how formally they were equipped and displayed. The correct answer for one Peerless 67 Series may not be identical to another.

A buyer aiming for strict authenticity should let the car's body style, period photos, and surviving trim details guide the decision. Blackwalls tend to read more restrained and understated, while whitewall variants can emphasize the prestige and visual richness expected of a high-end American car from the late 1920s.

A properly selected and properly mounted new bias-ply tire can be suitable for operating a Peerless 67 Series on public roads within the limits of a 1926 automobile. Tire safety, however, is only one part of the equation on a pre-war car that may still have original-style brakes, steering, suspension, and wheels. The condition of the entire chassis matters as much as the tire itself.

Road use should be approached as vintage motoring, not modern commuting. Before putting a Peerless 67 Series into regular traffic, make sure the wheels, tubes, brakes, bearings, steering components, and inflation practices are all in good order so the tire is working within a sound mechanical package.

Before driving a Peerless 67 Series, check tire pressure, visible sidewall condition, valve stems, wheel fasteners, and any sign of tube-related air loss or bead movement. On a car of this age, it is also wise to inspect the rim and the tire's seated position after the vehicle has been sitting. A brief walk-around can reveal a great deal before the car ever moves.

Those checks should be paired with the mechanical basics that matter on any substantial pre-war car: steering play, brake response, fluid levels, and wheel-bearing feel. A Peerless 67 Series is a large, dignified machine, but it should still be driven only after the same thoughtful preparation that any serious collector car deserves.

A Peerless 67 Series should be driven at conservative speeds that respect both the vintage bias-ply tire design and the capabilities of a 1926 automobile. Even with fresh tires, the handling, braking, and road feel of a pre-war luxury car are very different from later cars. Stability and comfort come from smooth inputs and moderate pace rather than modern traffic speeds.

The sensible approach is to treat a Peerless 67 Series as a touring or event car, not a high-speed road machine. Let road conditions, vehicle condition, weather, and the car's own responses set the pace, and keep enough margin that braking distances, steering correction, and tire heat never become part of the drama.
