1931 Peerless came from a proud American luxury tradition, but by this point the marque was nearing the end of its automobile production and offered a compact range that still reflected upscale pre-war engineering and style. Buyers looking at 1931 Peerless often encounter a more model-specific tire picture than they might expect, because the Standard, Master, Custom, and 61A each used their own distinct 19-inch bias-ply size. That means the real choice is less about switching constructions and more about identifying the correct model first, then confirming the proper size within that shared 19-inch wheel diameter family. Start with the model name on the car before narrowing down the tire that belongs on it.
Which Tire Size Is Right for Your 1931 Peerless
Four tire sizes are used across 1931 Peerless models, and they vary by model rather than being shared across the full range. Because every size mounts on a 19-inch rim and all of them are bias-ply designs, the key decision is confirming which Peerless model you have before choosing a tire. Understanding that distinction first helps you move directly to the right size and the right style for your car.
Year(s): 1931|Fit(s): 61A|Construction: Bias Ply|Rim: 19-in rim
5.25-19 is a numeric bias-ply size in which 5.25 refers to the nominal section width and 19 is the wheel diameter in inches. This size is specific to the 1931 Peerless 61A rather than universal across the year and make, and available product details do not add brand or sidewall-style alternatives here. It is the size to pursue when you are matching the 61A specifically and want to stay with the period-correct construction used on these early-1930s cars.
Year(s): 1931|Fit(s): Custom|Construction: Bias Ply|Rim: 19 in
650-19 is a numeric bias-ply size, with 6.50 indicating nominal section width and 19 identifying the wheel diameter in inches. Firestone and Lester offerings are available in this size, with both Blackwall and Wide Whitewall sidewall styles represented; products with listed fitment details use 19-inch rims and a 3.25 to 3.50 inch rim-width range, and one offering carries a 1430@36 psi load-and-pressure figure. This size is specific to the 1931 Peerless Custom, so it is the right path for owners restoring or driving that model while keeping the correct pre-war bias-ply look and feel.
Year(s): 1931|Fit(s): Master|Construction: Bias Ply|Rim: 19 in
600-19 is a numeric bias-ply size that denotes a nominal 6.00-inch section width on a 19-inch wheel. Lester is available in this size with a Wide Whitewall sidewall style, keeping the appearance in line with an upscale pre-war presentation. Because this size belongs only to the 1931 Peerless Master, it is the proper choice when your goal is model-correct fitment with traditional bias-ply construction.
Year(s): 1931|Fit(s): Standard|Construction: Bias Ply|Rim: 19 in
550-19 is a numeric bias-ply size, with 5.50 representing the nominal section width and 19 the wheel diameter in inches. BFGoodrich products are offered in both Blackwall and Wide Whitewall versions, with a listed rim-width range of 2.50 to 3.00 inches and a 1040@32 psi load-and-pressure figure. This size is specific to the 1931 Peerless Standard, making it the correct route for a model-appropriate restoration or for keeping the car in its original-era construction type.
All four sizes share a 19-inch rim diameter, but wheel width should still be confirmed against the actual rim before finalizing a tire choice.
1931 Peerless Models
Four 1931 Peerless models are covered here, and each one uses its own tire size. That means year and make alone are not enough for tire selection on 1931 Peerless; identifying whether your car is a Standard, Master, Custom, or 61A is the practical first step. Select your model below to narrow the fitment history and tire choices to the version of Peerless you own.
1931 Peerless 61A
The 1931 Peerless 61A sits within the marque's final automotive chapter, when Peerless still carried the visual dignity and engineering character expected of an upper-end American car. Its tires mount on 19-inch wheels, and the 61A stands apart here by using its own dedicated size rather than sharing with the other 1931 Peerless models.
The 1931 Peerless Custom reflects the marque's luxury leanings, with the kind of formal pre-war presence buyers often want to preserve carefully during restoration. It uses a 19-inch wheel and takes the largest listed size in this group, making model identification especially important before choosing a tire.
The 1931 Peerless Master occupied the middle of the range and would have appealed to buyers wanting Peerless character in a slightly less formal package than the top offerings. Its tires fit 19-inch rims, and the Master uses its own standalone size within the 1931 Peerless lineup.
The 1931 Peerless Standard was the more straightforward expression of the brand, but it still belongs to the same pre-war luxury heritage that makes correct details matter today. It mounts on 19-inch wheels and uses the narrowest of the four listed sizes, so choosing by model name matters as much as choosing by year and make.
Ten products are available across four tire sizes for 1931 Peerless vehicles. 650-19 includes seven Firestone and Lester bias-ply options in Blackwall and Wide Whitewall styles, 600-19 has one Lester bias-ply Wide Whitewall, and 550-19 offers two BFGoodrich bias-ply choices in Blackwall and Wide Whitewall styles.
These answers sort out the model-by-model tire differences for 1931 Peerless, explain what the numeric sizes mean, and cover sidewall style choices, wheel setup, road use, and long-term care for a low-use pre-war collector car.
Size Basics & Fitment
What tire sizes fit 1931 Peerless vehicles?
1931 Peerless vehicles use four distinct tire sizes, and each size belongs to a specific model. The 61A uses 5.25-19, the Custom uses 650-19, the Master uses 600-19, and the Standard uses 550-19. All four sizes mount on 19-inch rims, but they are not interchangeable as a year-wide fitment because each model was built around its own tire sizing.
That means the first question is not simply whether you own a 1931 Peerless, but which 1931 Peerless model you own. Once the model is confirmed, you can narrow the tire choice to the correct size and then compare available sidewall styles or brand offerings within that size. If your car has been restored previously, it is wise to compare the tire size already on the car with the actual model identification before replacing anything.
What does 650-19 mean on a 1931 Peerless tire?
On a 1931 Peerless tire, 650-19 is a numeric bias-ply size. The 6.50 figure refers to the nominal section width in inches, while 19 is the wheel diameter in inches. For 1931 Peerless fitment, that size applies to the Custom model and keeps the car in the same general construction style used in the pre-war era.
Numeric bias-ply sizing can look unfamiliar to buyers used to modern metric radials, but it is standard language for many vintage American cars. If you are shopping for a 1931 Peerless Custom, the important point is matching both the 650 width designation and the 19-inch rim diameter. After that, the remaining choices usually come down to brand preference and whether you want a blackwall or a whitewall appearance.
Do all 1931 Peerless models use the same tire size?
No, 1931 Peerless models do not all use the same tire size. The Standard, Master, Custom, and 61A each have their own size assignment, even though all four use 19-inch rims. That shared wheel diameter can make the range look similar at first glance, but the width designations differ from model to model.
This matters because a buyer who identifies only the year and make can still end up on the wrong size if the model is overlooked. Restorations from earlier decades sometimes mixed parts, so checking the body tag, title, club resources, or known model features can save time before choosing tires. Once the model is nailed down, the tire decision becomes much more straightforward.
Buying the Right Tire
What sidewall styles are available for 1931 Peerless tires?
1931 Peerless tires are available in both Blackwall and Wide Whitewall styles, depending on the size. The 650-19 size for the Custom has both Blackwall and Wide Whitewall options, the 600-19 size for the Master is represented here by a Wide Whitewall offering, and the 550-19 size for the Standard has both Blackwall and Wide Whitewall choices. All of these are bias-ply tires, which keeps the construction in line with the period.
Sidewall style affects the visual character of a pre-war car almost as much as wheel finish or hubcaps. A blackwall usually suits a more restrained look, while a wide whitewall creates a dressier presentation many owners want on upper-end early-1930s cars. For show-focused restoration, it is smart to compare your chosen sidewall style with period photos, marque club guidance, and the way your specific Peerless body style would have been presented.
What brands make tires for 1931 Peerless vehicles?
Several brands are represented across 1931 Peerless tire sizes. Firestone and Lester are available in 650-19 for the Custom, Lester appears in 600-19 for the Master, and BFGoodrich is offered in 550-19 for the Standard. All listed choices are bias-ply tires suited to the era and visual character of a 1931 Peerless.
Brand choice on a pre-war car often comes down to the combination of size availability and preferred sidewall appearance rather than a modern-style performance comparison. Some sizes simply offer more variety than others, especially the Custom's 650-19 fitment. If your goal is a consistent look across a full set, confirm the exact sidewall treatment you want first and then choose among the brands available in the size that belongs to your model.
What is the difference between Firestone and Lester 650-19 tires for 1931 Peerless Custom models?
For 1931 Peerless Custom models in 650-19, Firestone and Lester both appear in bias-ply form, but they are offered with different combinations of sidewall treatment and listed specifications. Firestone appears in Blackwall form and in Wide Whitewall Balloon form, with listed wheel-fit details of 3.25 to 3.50 inch rim widths on the Balloon versions, and one Firestone whitewall includes a 1430@36 psi load-and-pressure figure. Lester appears here as a Wide Whitewall bias-ply option.
That means the choice is less about changing the basic fitment and more about selecting the look and specification set that best suits your Custom. Owners pursuing a more formal presentation may lean toward a whitewall, while others may prefer a blackwall for a more restrained appearance. When comparing within 650-19, use the actual rim width on your wheel and the sidewall style you want as the deciding factors.
Fitting & Setup
What rim width do 1931 Peerless tires require?
Rim width guidance is available for some 1931 Peerless tire sizes. The 650-19 size used on the Custom is listed with a 3.25 to 3.50 inch rim-width range on certain Firestone offerings, while the 550-19 size used on the Standard is listed with a 2.50 to 3.00 inch rim-width range on the BFGoodrich options. All of the listed sizes use 19-inch rim diameter, but width still needs to match the specific tire.
Rim diameter alone is not enough to confirm compatibility on a pre-war wheel. If your Peerless has original wheels, older restoration work, or replacement rims from another source, measure the wheel and compare it to the range listed for the exact tire size you plan to use. That extra check helps preserve proper casing shape and keeps the fitment closer to what the tire was designed to support.
Can the original 1931 Peerless wheels be used with all tire sizes?
All listed 1931 Peerless tire sizes use 19-inch rims, so there is a shared wheel diameter across the Standard, Master, Custom, and 61A. Even so, the cars do not all use the same tire size, and listed rim-width ranges differ where they are available. A 19-inch wheel from one model should not be assumed correct for another model simply because the diameter matches.
Original wheels can often remain part of the solution, but the correct approach is to match the wheel to the tire size assigned to your specific model. Pre-war restorations sometimes involve swapped wheels, and that can blur the distinction between what fits physically and what fits correctly. Confirm the model, confirm the tire size, and then verify the wheel width before relying on an existing wheel set.
Maintenance, Storage & Longevity
How should I store a 1931 Peerless when the tires are fitted?
A 1931 Peerless should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber. Because these are bias-ply tires, long static periods can also encourage temporary flat-spotting and make sidewall aging more noticeable if the car sits on one position for months at a time.
Maintaining correct pressure, rolling the car periodically, or using appropriate supports during long storage can help reduce casing stress. Clean floors and a stable environment matter as much as the tires themselves on a low-use pre-war car. If the Peerless will sit for a season, include the spare in the same inspection routine so your full set ages evenly and remains ready for occasional road use.
How long do tires on a 1931 Peerless typically last?
Tires on a 1931 Peerless should be judged more by age and condition than by mileage, because collector cars often cover limited annual miles. A sound rule is to begin close inspection once a tire reaches about five to seven years of service and to consider replacement as it approaches ten years, even if the tread still looks strong. The manufacturing date can be checked on the tire itself.
That timeline matters on a pre-war car because low miles can hide age-related hardening, sidewall cracking, and reduced flexibility. A 1931 Peerless used only for shows or occasional drives may appear fine while the rubber is already past its best working life. If the car has older tires of uncertain age, replacement is usually a smarter starting point than trying to stretch more seasons out of them.
How often should tires on a 1931 Peerless be inspected?
Tires on a 1931 Peerless should be inspected before every drive and again before any longer outing. Look for sidewall cracking, uneven wear, embedded debris, cuts, bulges, and any sign that the tire is losing pressure. Since these are vintage-style bias-ply tires on an early-1930s car, the condition of the valve stems and the overall age of the spare deserve the same attention as the four tires on the ground.
Regular inspection is especially important because collector cars can sit for weeks and then be asked to run at road speed with little recent use. Catching a weathered sidewall or a slow leak in the garage is far easier than dealing with it on a tour. Make tire inspection part of the same routine as checking fluids, brakes, and steering play before heading out.
Restoration & Authenticity
What tires were originally fitted to the 1931 Peerless Standard?
The 1931 Peerless Standard uses 550-19, and the original-era construction for a car of this period would have been bias-ply rather than radial. That aligns with the available reproduction choices for the Standard today, which stay within the same broad construction family. While sidewall presentation could vary by market taste or owner preference, the underlying type for a 1931 American luxury car remains firmly pre-radial.
For a restoration, the safest path is to start with 550-19 bias-ply sizing and then refine the sidewall style to suit your goals. Owners aiming for event-level authenticity should compare their choice against factory literature, surviving photographs, and Peerless club knowledge for body-style and presentation nuances. Brand name should not be assumed as original unless you have period evidence tied to your specific car.
Does correct tire fitment matter for showing a 1931 Peerless?
Correct tire fitment matters on a 1931 Peerless because size, construction type, and sidewall appearance all influence whether the car looks convincingly of its period. A wrong-size tire can alter stance and proportion, while an incorrect sidewall treatment can change the car's visual character almost immediately. On a judged pre-war car, those details are often noticed even by viewers who are not tire specialists.
For a car intended for serious show use, matching the model-specific size is the first priority, since 1931 Peerless did not use one universal size across the whole lineup. After that, choose the sidewall style that best supports your restoration theme and confirm event expectations with marque clubs or judging guidelines. A car built for touring can accept a little more personal preference, but a judged restoration benefits from discipline in these details.
What is the difference between blackwall and whitewall tires for 1931 Peerless restoration work?
For 1931 Peerless restoration work, the main difference between blackwall and whitewall tires is visual presentation rather than basic fitment when both are offered in the same size. Blackwalls give a more restrained and utilitarian look, while wide whitewalls create a more formal, upscale appearance that many owners associate with premium pre-war automobiles. Both styles are available within parts of the 1931 Peerless range, depending on the model's tire size.
The right choice depends on how you want the finished car to read from a few steps away. A formal sedan or luxury-oriented restoration often looks more complete with a whitewall, while some owners prefer blackwalls for a simpler and more understated period impression. If you are chasing authenticity rather than taste alone, period photography and Peerless-focused hobby resources are the best tie-breakers.
Safety & Road Use
Are 1931 Peerless tires safe for highway driving?
1931 Peerless tires can be used for normal road driving when they are the correct size, in sound condition, properly inflated, and mounted on suitable wheels. The available 1931 Peerless offerings here are bias-ply tires, which means they deliver an authentic pre-war driving feel rather than a modern radial response. No speed-rating markings are presented here for these sizes, so the practical road-speed limit is often shaped as much by the vehicle's brakes, steering, suspension, and general age as by the tire itself.
A well-sorted 1931 Peerless is best treated like the pre-war car it is, with conservative speeds and room for longer stopping distances. Before regular highway use, confirm that the tires are fresh enough, the pressures are correct, and the rest of the chassis is equally ready for sustained travel. Safe road use on a car of this era is always a whole-vehicle question, not just a tire question.
What inflation pressure should I use for 1931 Peerless tires?
Inflation pressure on a 1931 Peerless should follow the recommendation for the exact tire size and the vehicle's original guidance where available. Among the listed options, 550-19 appears with a 1040@32 psi load-and-pressure figure, and one 650-19 offering appears with a 1430@36 psi figure. Those numbers belong to those specific sizes and products and should not be transferred across the rest of the 1931 Peerless range.
The best practice is to begin with the owner's manual or period factory recommendation for your specific model, then compare that with the tire maker's rated information for the reproduction tire you choose. Pressure changes ride, handling feel, and casing shape on bias-ply tires more noticeably than many owners expect. If your Peerless carries passengers regularly or is driven on tours, recheck cold inflation before each outing rather than assuming last season's setting is still correct.
What should I check before taking a 1931 Peerless on a longer drive?
Before a longer drive in a 1931 Peerless, inspect all five tires for cracking, tread separation, cuts, sidewall damage, bulges, and proper inflation. Make sure the spare is usable, the valve stems are sound, and the wheels themselves show no obvious issues at the rim edge or around the mounting area. Since these are pre-war bias-ply fitments, any age-related weakness deserves attention before distance driving.
Tire checks should be part of a broader readiness routine on a car from 1931. Brakes, wheel bearings, steering play, cooling system condition, and fuel-system reliability all matter just as much once the trip goes beyond a short local drive. If the Peerless has been sitting, a short shakedown run close to home is a smarter first step than heading straight out on a tour.
