1929 Peerless Tire Fitment Guide

1929 Peerless vehicles use six listed sizes across three model lines, and each series has its own pair of fitments. The 125 Series uses 31X6.20 or 650-19, the 61Series uses 29X5.25 or 5.25-19, and the 81 Series uses 29X5.50 or 550-19. All of these sizes mount on 19-inch wheels, and listed rim-width guidance appears on supported numeric sizes such as 650-19 at 3.25 to 3.50 inches and 550-19 at 2.50 to 3.00 inches.

The practical takeaway is that year and make alone are not enough for a 1929 Peerless tire decision. You need to identify the series first, then confirm whether your car is being matched to the antique diameter-by-section code or the numeric 19-inch code associated with that same model family. Once that is settled, sidewall style and brand choice become much easier to sort.

On a 1929 Peerless, 31X6.20 is an antique diameter-by-section size. The first number gives the overall tire diameter in inches, so 31 means a 31-inch-tall tire, and 6.20 refers to the nominal section width. This style of sizing was common in the late 1920s, especially on cars that bridged older tire nomenclature and newer numeric replacement conventions.

A 1929 Peerless owner should read 31X6.20 as a model-specific fitment clue, not just a generic old-tire marking. It belongs with the 125 Series and points you toward the larger fitment family used on that series. If your wheel and car are from the 125 Series, this code helps anchor a correct-era search before you compare supported numeric alternatives such as 650-19.

On a 1929 Peerless, 650-19 is a numeric bias-ply size. The 6.50 portion represents the nominal section width in inches, while 19 is the wheel diameter in inches. This code is used on the 125 Series and corresponds to the same model family served by the older-style 31X6.20 marking, but in the more familiar numeric convention used on many replacement bias-ply tires.

That matters because a 1929 Peerless owner shopping by sidewall style or brand will usually find more direct product listings under 650-19 than under the antique-format equivalent. It is still a model-specific size, so it should not be assumed to fit the 61Series or 81 Series. Confirm the series, then confirm the wheel width if you are working with one of the listed 650-19 products.

1929 Peerless tires are currently represented in both blackwall and wide whitewall styles in the supported 650-19 and 550-19 sizes. Firestone and Lester offerings in 650-19 include blackwall and wide whitewall choices, and BFGoodrich offerings in 550-19 do the same. Both styles suit the late-1920s period, but they create a very different visual impression on a large pre-war automobile.

Blackwalls generally deliver a more restrained, technical look, while wide whitewalls give a fuller luxury-era appearance that many owners associate with upscale American cars of the period. The right choice depends on how your 1929 Peerless is being presented: formal touring car, judged restoration, or regular collector use. If authenticity is a concern, compare your car's historical photos and consult a Peerless club or marque specialist.

Three brands appear in the supported 1929 Peerless tire range. Firestone and Lester are offered in 650-19 for the 125 Series, while BFGoodrich is offered in 550-19 for the 81 Series. All listed products for these sizes are bias-ply tires, which is consistent with the construction type expected for a 1929 American luxury car.

Brand choice on a 1929 Peerless often comes down to the exact size your series uses and the sidewall look you want. The 125 Series owner has more brand variety in 650-19, while the 81 Series owner choosing 550-19 is selecting within BFGoodrich offerings. Once the correct size is confirmed, compare blackwall versus wide whitewall and any available load or rim-width information before narrowing further.

For the 1929 Peerless 125 Series, 650-19 appears in Firestone and Lester bias-ply offerings. Firestone choices include blackwall and wide whitewall versions within the Classic Bias Ply and Balloon families, and some Firestone Balloon listings specify a 3.25 to 3.50 inch rim-width range with load figures up to 1430 pounds at 36 psi. Lester is represented in a wide whitewall 650-19 version and carries a heavier listed weight than the basic Firestone blackwall option.

A 125 Series owner should treat these as appearance-and-spec comparisons within the same basic size rather than as interchangeable styling details alone. Firestone provides the broader spread of listed options, while Lester gives another traditional whitewall presentation in the same fitment. If your focus is wheel compatibility or load markings, review those details product by product instead of assuming every 650-19 version is built exactly the same way.

Rim-width guidance is listed for some supported 1929 Peerless sizes. In 650-19, certain Firestone Balloon products specify a usable rim-width range of 3.25 to 3.50 inches. In 550-19, BFGoodrich products specify a 2.50 to 3.00 inch rim-width range. Those figures apply to those listed products and should be matched to the wheel actually on the car.

This matters because all of the 1929 Peerless sizes here use 19-inch rims, so wheel diameter alone does not settle the fitment question. A 125 Series owner should not assume the narrower 81 Series wheel width is acceptable just because both use a 19-inch wheel. Measure the wheel, confirm the series, and keep the rim-width range tied to the exact size and product you intend to run.

Original 1929 Peerless wheels can only be considered across all listed tire sizes in one limited sense: every size in this year-make group is built around a 19-inch wheel diameter. That means a 19-inch wheel is part of every fitment family here, whether the marking is antique-style like 31X6.20 or numeric like 650-19. Wheel diameter compatibility is shared, but the sizes themselves remain model-specific.

A 1929 Peerless owner should not treat that common diameter as proof that every wheel works with every tire in the lineup. The 125 Series uses a larger tire family than the 61Series and 81 Series, and supported products show different rim-width ranges between 650-19 and 550-19. If the car has been restored or altered over the years, verify the actual wheel dimensions before moving from one size family to another.

A stored 1929 Peerless should be kept in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources that accelerate sidewall aging. Bias-ply tires are especially prone to flat-spotting when they sit in one position for long periods, so periodic rolling or using stands to reduce continuous load can help. Clean floors and stable temperatures are kinder to old-car tires than damp concrete and wide seasonal swings.

That approach protects both appearance and drivability on a pre-war luxury car that may spend long stretches parked between events. If the car remains on its tires, maintain proper inflation and move it occasionally so the casing is not always loaded in the same spot. If it is stored on stands, support the chassis safely and still inspect the tires regularly for cracking, drying, or distortion before returning the car to service.

Tire life on a 1929 Peerless is usually governed more by age than by mileage. Collector-car tires should be evaluated closely once they reach about five to seven years of service, and many owners begin serious replacement consideration by around ten years regardless of tread depth. The DOT date code on the tire helps establish age, and visual condition matters just as much on a low-use pre-war car.

That is especially important because a 1929 Peerless may see only occasional touring miles, which can make old tires look usable long after the casing has hardened or degraded. If the car has spent time in sunlight or poor storage conditions, replacement may come sooner. A tire with plenty of tread can still be the wrong tire to trust for road use if its age and condition are working against it.

Tires on a 1929 Peerless should be checked before every drive and again before any longer outing. Look for sidewall cracks, cuts, bulges, uneven tread wear, and signs that the tire is losing pressure between uses. On a car of this age, it is also wise to inspect valve stems and the spare, since long-stored collector cars often reveal problems only when they are brought back into regular movement.

Frequent inspection makes more difference on a pre-war car than on a modern daily driver because the tire is only one part of an older mechanical system with less margin for neglect. A quick walkaround before each use helps catch aging or storage-related issues early. If the car has not been driven in months, add a closer check of wheel condition and inflation before trusting it on public roads.

A 1929 Peerless 125 Series would originally have been a bias-ply car, and the listed fitment family for that model is 31X6.20 or 650-19. That pairing reflects the transition-era sizing language seen in late-1920s American cars, where an antique diameter-by-section code and a numeric replacement-style code often point to the same model family. No original-equipment brand should be assumed without car-specific historical confirmation.

For restoration work, the key is matching the 125 Series to its correct size family first, then choosing the sidewall treatment and product style that suits your goal. If the car is headed for marque judging, consult Peerless club resources, period photos, and surviving factory literature for market-specific details. Construction type, sidewall appearance, and correct series identification all matter more than choosing a familiar modern brand name.

Correct tire fitment matters on a 1929 Peerless because show judging often looks at size, construction, and sidewall appearance as part of the car's overall authenticity. A Peerless restored with the wrong series-specific size, or with a sidewall treatment that does not suit the car's period presentation, can look visibly out of step even to non-experts. On a late-1920s luxury car, tires contribute heavily to stance and visual proportion.

That means a show-focused owner should begin with the correct model family and then evaluate whether blackwall or wide whitewall best matches the car's intended presentation and judging standard. Event rules vary, and some clubs are stricter than others about originality details. Before finalizing a concours setup, compare your planned tire choice with marque references and the standards of the specific event where the car will be judged.

For the 1929 Peerless sizes that have current product support, blackwall and wide whitewall versions are both available. In 650-19, Firestone and Lester offerings include both looks, and in 550-19, BFGoodrich does as well. The construction remains bias-ply either way, so the main difference is visual character rather than a change from one tire type to another.

On a restoration, that visual choice has a major effect on how the car reads. Blackwalls tend to make a 1929 Peerless look slightly more restrained and utilitarian, while a wide whitewall emphasizes luxury-era formality and presence. The right answer depends on the body style, the presentation you want, and the standards of the club or show where the car will appear.

1929 Peerless tires in the listed supported sizes are bias-ply products, and no explicit modern speed ratings are shown here for them. That does not automatically rule out highway use, but it does mean a 1929 Peerless should be driven within the broader limits of a late-1920s automobile, including its braking, suspension, steering, and overall mechanical condition. On cars of this era, the chassis often becomes the governing factor before a reproduction bias-ply tire does.

A roadworthy 1929 Peerless can be used on modern roads with care, but sustained high-speed travel is a separate question from occasional touring. The safest approach is to match the correct size to the correct series, keep the tires in sound condition, and drive in a way that respects the car's age and design. If you plan regular longer-distance use, have the entire car evaluated, not just the tires.

Inflation pressure on a 1929 Peerless should be set by the exact tire size, the product's own rated information, and the factory guidance for the car when available. Among the supported sizes, some 650-19 products list a maximum load of 1430 pounds at 36 psi, and 550-19 products list 1040 pounds at 32 psi. Those figures are product ratings, not universal settings to be copied across every 1929 Peerless tire size.

Use those numbers as a ceiling tied to that specific product, then compare them with the pressure guidance in period owner or service literature for your series. A 125 Series should not be assigned the same operating pressure as an 81 Series simply because both use 19-inch wheels. When in doubt, keep the pressure decision tied to the exact size and tire you are using rather than the year and make alone.

Before a longer drive in a 1929 Peerless, inspect every tire for cracking, cuts, bulges, exposed fabric, irregular wear, and pressure loss, then check the spare as well. Confirm that the tires match the correct series-specific size family and that the valve stems are in good condition. On a pre-war car, tire condition should be part of a broader check that also includes brakes, steering play, wheel bearings, fluids, lights, and the cooling system.

Longer trips place more sustained load and heat into an old-car tire than short local drives, so small issues become more meaningful. If the car has sat for months, plan a short local shakedown before committing to distance. A well-prepared 1929 Peerless is far more enjoyable and far less stressful when the tire inspection is treated as one step in a complete road-readiness routine.
