The 1929 Peerless 61Series comes from the final years of one of America's respected luxury marques, a period when large, well-appointed cars still carried distinctly prewar proportions and road manners. Owners restoring or maintaining one today usually want tire choices that suit both the car's appearance and its age. For this model, the key fitment question starts with two bias-ply sizes: 29X5.25 and 5.25-19. Those sizes reflect different vintage sizing conventions rather than a modern tire menu, so understanding the numbering matters before making a selection. The right choice begins with confirming which wheel setup is on the car and whether the goal is preservation, touring use, or a restoration-oriented presentation.
Which Tire Size Is Right for The 1929 Peerless 61Series
The 1929 Peerless 61Series uses two primary tire sizes, and the first step is confirming which wheel and tire setup is actually on the car. Both fitments are bias-ply, but they follow different vintage sizing systems and use different rim diameters, so wheel diameter must be verified before selecting a replacement.
A 29X5.25 size uses an older diameter-by-section format, where the first number refers to the tire's approximate outside diameter and the second refers to section width. On the 1929 Peerless 61Series, this is a bias-ply fitment suited to an early automotive wheel setup that should be checked carefully before replacement. Antique-format sizes appeal to owners who want a strongly period-style look and sizing convention. Choosing this size starts with confirming the wheel itself, since the notation does not read like later numeric bias-ply sizes and can be unfamiliar to modern buyers.
A 5.25-19 tire uses the classic numeric bias-ply format, with 5.25 indicating nominal section width in inches and 19 identifying the rim diameter. For the 1929 Peerless 61Series, this size represents a more familiar vintage passenger-car bias-ply convention than the antique diameter-based format. Numeric bias-ply sizing is often easier for collectors to interpret when matching tires to existing wheels and restoration needs. This size should be evaluated by confirming the 19-inch wheel setup on the car and deciding whether the goal is authentic vintage character, regular road use, or display-focused presentation.
Sub-model fitment is straightforward here because the covered 6 Cyl. configuration uses the same two primary bias-ply tire sizes. The important step is not trim identification so much as confirming which wheel and tire setup remains on the car today.

The 1929 Peerless 61Series 6 Cyl. uses the same two bias-ply fitment paths found at the model level, so the main task is matching the tire to the wheel currently on the vehicle. That makes wheel confirmation especially important before choosing a period-style replacement or planning any road-use refresh.
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.
Frequently Asked Questions
Owners researching 1929 Peerless 61Series tires usually need clarity on vintage size notation, wheel diameter, restoration-minded appearance, and what to inspect before putting an early luxury car back on the road.
Tire Size & Fitment
What tire size fits a 1929 Peerless 61Series?
The 1929 Peerless 61Series uses two primary bias-ply tire sizes: 29X5.25 and 5.25-19. Those are both correct fitment paths for this model, but they are not the same size expressed two different ways. Each one belongs to a different vintage sizing convention and wheel setup.
The practical decision is confirming which tires and wheels are actually on the car before ordering replacements. A restored vehicle, an older survivor, or a car that has been apart for many years may not still wear its intended setup. Checking the mounted tire markings and the wheel diameter is the safest way to choose between these two fitments.
What size rim does a 1929 Peerless 61Series use?
The 1929 Peerless 61Series uses two different rim diameters depending on tire size. The 29X5.25 fitment is associated with a 5.0-inch rim diameter, while the 5.25-19 fitment uses a 19-inch rim. That makes wheel confirmation the first step in selecting replacement tires.
Vintage cars can be especially tricky because old tire markings, replacement wheels, and long-term restoration work sometimes leave the current setup different from expectations. Looking at the wheel itself and the markings on the existing tire helps prevent choosing a tire by name alone. On this Peerless, rim diameter matters more than appearance when narrowing the fitment.
What does 29X5.25 mean on a 1929 Peerless 61Series?
On a 1929 Peerless 61Series, 29X5.25 is an antique diameter-by-section tire size. The 29 refers to the tire's approximate overall diameter, and the 5.25 refers to its section width. It is a bias-ply size from an earlier sizing system than the later numeric passenger-car format.
That older notation is important because it should not be confused with a modern metric or later alphanumeric size. Buyers working on prewar cars often see more than one vintage sizing style on the same model family, and this Peerless is an example. Matching the tire to the wheel already on the car is more useful than trying to compare the number to a newer tire format.
Choosing the Right Tire
What should I consider when choosing a 29X5.25 or 5.25-19 tire for a 1929 Peerless 61Series?
Start with the exact size already matched to the car's wheel setup, because the 1929 Peerless 61Series uses both 29X5.25 and 5.25-19 bias-ply fitments. Those sizes represent different rim diameters and different vintage sizing conventions, so choosing by appearance alone can lead to the wrong tire.
After size is confirmed, think about how the car will be used. A restoration-oriented display car, a lightly driven collector car, and a vehicle prepared for regular touring may all call for slightly different priorities. Keeping the proper vintage format and overall presentation usually matters as much as the raw dimensions on a prewar luxury automobile.
How do I choose between the available 1929 Peerless 61Series tire sizes?
Choosing between the two tire sizes on a 1929 Peerless 61Series is mainly a wheel-identification job. The car uses 29X5.25 and 5.25-19, both in bias-ply construction, and each size belongs to its own wheel diameter. The correct tire is the one that matches the wheel currently fitted to the vehicle.
That matters because many collector cars have seen decades of repairs, parts replacement, and restoration work. A car may have wheels changed long ago, or it may have been assembled from components during restoration. Reading the tire sidewall, measuring the wheel, and confirming clearance around fenders and steering components helps narrow the choice before any cosmetic preference enters the picture.
Why does the 1929 Peerless 61Series have more than one tire size?
The 1929 Peerless 61Series has more than one tire size because vintage vehicles often appear with multiple period fitment conventions tied to different wheel setups. In this case, the model uses both 29X5.25 and 5.25-19 bias-ply sizes, which are distinct fitments rather than one modern-style equivalent listing.
For a buyer, that means the selection process starts with the car in front of you rather than the model name alone. An early luxury car may have been restored at different times or preserved with older replacement parts still in service. Verifying the wheel diameter and existing tire markings keeps the fitment process grounded in the actual vehicle rather than assumptions.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Peerless 61Series?
A period-style 1929 Peerless 61Series usually starts with retaining the correct vintage bias-ply sizing format already matched to the car's wheels. Both 29X5.25 and 5.25-19 are appropriate primary fitments for this model, and each preserves an early automotive tire presentation that suits a late-1920s luxury car.
The best choice depends on which wheel setup is actually installed and how exact the restoration needs to be. For a historically focused car, staying within the proper size convention is often as important as selecting a tire that simply mounts. When exact originality matters, marque-specific references and restoration records remain the best guide beyond basic fitment.
Does correct tire fitment matter for a 1929 Peerless 61Series restoration?
Correct tire fitment matters a great deal on a 1929 Peerless 61Series because tire size strongly affects the car's stance, visual balance, and overall period impression. On prewar automobiles, the wrong sizing convention can look noticeably out of place even if the tire seems generally close in width or height.
Proper fitment also helps avoid practical issues once the car is driven. A mismatch between tire and wheel can complicate mounting, alter clearances, or create an appearance that does not suit the vehicle's era. Restorers usually get the best result by confirming the wheel setup first and treating the tire as part of the car's visual architecture, not just a consumable part.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Peerless 61Series?
Yes, modifications can affect tire fitment on a 1929 Peerless 61Series. If the car has replacement wheels, brake work that altered wheel mounting, suspension rebuilding with changed ride height, or body repairs that affect clearance, the original tire choice may need closer evaluation before a new set is installed.
That does not mean the car cannot use its proper vintage size, but it does mean checking the actual setup matters. Steering travel, fender clearance, and wheel diameter should all be confirmed on the finished vehicle. On an older restoration, even small changes made many years ago can influence whether a vintage-size bias-ply tire is still the right physical match.
What should I inspect before driving a 1929 Peerless 61Series on new tires?
Before driving a 1929 Peerless 61Series on new tires, inspect the wheels for condition, confirm the tires are mounted in the correct size, and look over the valve stems, fasteners, and wheel hardware. It also helps to check steering movement lock to lock and make sure nothing contacts the tire through its travel.
A careful pre-drive inspection should also include overall tire pressure, visible sidewall condition, and basic chassis condition around springs, steering links, and brakes. Early collector cars often spend long periods parked, so the first road outing deserves extra attention. A short, slow test drive followed by a second inspection can reveal clearance or mounting issues before a longer run.
How should tires on a collector 1929 Peerless 61Series be maintained?
Tires on a collector 1929 Peerless 61Series should be maintained with regular pressure checks, routine visual inspections, and clean storage conditions. Even when tread wear is minimal, collector-car tires can age from time, sunlight, heat, and long periods of inactivity. Sidewall cracking, cuts, bulges, and persistent air loss all deserve attention.
Good storage habits matter almost as much as mileage on a prewar car. Keeping the vehicle away from prolonged sun, moisture, and ozone sources helps preserve the tires between drives. Moving the car periodically and inspecting the wheels and tires before each outing is especially helpful on a low-use Peerless, where age and storage conditions often matter more than accumulated road miles.
