In 1934, Reo stood apart as an independent American make offering stylish, upper-middle-market cars with a strong emphasis on design and road presence. The 1934 Reo lineup was compact in size but not simple in tire fitment, because the Flying Cloud and Royale did not share one universal size across the year. Two 16-inch bias-ply sizes appear on the Flying Cloud, while the Royale moves to an 18-inch bias-ply fitment, so the real choice starts with identifying the correct model and wheel diameter rather than comparing modern versus vintage construction. Before choosing a tire for a 1934 Reo, confirm whether you have a Flying Cloud or Royale and verify the wheel size on the car.
Which Tire Size Is Right for Your 1934 Reo
Three tire sizes are available for 1934 Reo vehicles, and they vary by model rather than being shared across the full lineup. The main decision is confirming which model you have and whether it uses a 16-inch or 18-inch wheel, since all three sizes are bias-ply rather than a bias-versus-radial choice. Understanding that distinction first makes it much easier to narrow down the right tire and sidewall style.
Year(s): 1934|Fit(s): Flying Cloud|Construction: Bias Ply|Rim: 16 in
650-16 is a numeric bias-ply size in which the 6.50 figure indicates nominal section width and the 16 indicates the wheel diameter in inches. It is offered in BFGoodrich, Coker Classic, Firestone, and Garfield versions with both blackwall and wide whitewall sidewall styles, and load-marked examples reach 1580 pounds at 32 psi. This size is specific to the 1934 Reo Flying Cloud rather than the full Reo range for the year. It suits owners who want an era-correct bias-ply fitment with a choice between understated blackwall appearance and more formal whitewall styling.
Year(s): 1934|Fit(s): Flying Cloud|Construction: Bias Ply|Rim: 16 in
700-16 is a numeric bias-ply size with a nominal 7.00-inch section width and a 16-inch wheel diameter. Brands in this size include Lester, Avon, BFGoodrich, and Firestone, with both blackwall and wide whitewall styles available; load-marked examples range up to 1800 pounds at 36 psi, 1900 pounds at 36 psi, and 1,874 pounds, and Avon carries an L speed rating with a 75 mph ceiling. This size is also specific to the 1934 Reo Flying Cloud, not the Royale. It is the larger of the two Flying Cloud fitments and is the one to compare against your car's existing wheel and restoration direction before choosing a product.
Year(s): 1934|Fit(s): Royale|Construction: Bias Ply|Rim: 18 in
650-18 is a numeric bias-ply size that uses a nominal 6.50-inch section width on an 18-inch wheel. Firestone products are available in this size with both blackwall and wide whitewall sidewall styles, and load-marked examples reach 1205 pounds at 36 psi. This size is specific to the 1934 Reo Royale and does not apply across the rest of the 1934 Reo line. It is the correct starting point for Royale owners seeking a traditional prewar bias-ply tire with period-appropriate appearance options.
Two 1934 Reo models are covered here: the Flying Cloud and the Royale. Tire size varies by model, and in the case of the Flying Cloud there are two 16-inch fitments to sort through, while the Royale uses an 18-inch size of its own. Select your model below to focus on the tire sizes, fitment history, and product options that apply to your specific 1934 Reo.
1934 Reo Flying Cloud
The 1934 Reo Flying Cloud is the more widely recognized Reo passenger-car name of the period, remembered for streamlined styling and the marque's effort to stay visually competitive in the mid-1930s market. Its tires mount on 16-inch wheels, and the key fitment task is determining which of the two listed bias-ply sizes belongs on your particular car or restoration plan.
The 1934 Reo Royale sat as a more upscale Reo offering, carrying the kind of formal presentation buyers expected from a premium prewar American car. Its tires mount on 18-inch wheels, which separates it immediately from the Flying Cloud and makes model identification especially important before choosing a tire.
Thirty-one products are available across three tire sizes for 1934 Reo vehicles. The 650-16 size includes 19 bias-ply options from BFGoodrich, Coker Classic, Firestone, and Garfield in blackwall and wide whitewall styles; 700-16 includes 10 bias-ply options from Lester, Avon, BFGoodrich, and Firestone in blackwall and wide whitewall styles; 650-18 includes 2 Firestone bias-ply options in blackwall and wide whitewall styles.
These FAQs cover how 1934 Reo tire sizes split between Flying Cloud and Royale models, what the numeric bias-ply codes mean, how sidewall style affects authenticity, and what to check before fitting prewar tires to a collector car.
Size Basics & Fitment
What tire sizes fit 1934 Reo vehicles?
Three tire sizes fit 1934 Reo vehicles, and they are tied to specific models rather than shared across the whole make. The Flying Cloud uses 650-16 and 700-16, both on 16-inch wheels, while the Royale uses 650-18 on 18-inch wheels. Rim-width guidance appears for the available products as 4.50 to 5.00 inches for 650-16 products with published dimensions, 4.50 to 5.50 inches for 700-16 products with published dimensions, and 3.25 to 3.50 inches for 650-18.
Model identification matters first on a 1934 Reo because the wheel diameter changes between the Flying Cloud and Royale. If you have a Flying Cloud, the next step is narrowing down whether your car calls for 650-16 or 700-16, then checking your actual wheel against the published rim-width range for the tire you are considering. That approach keeps the search focused on the right model and wheel size before you start choosing between blackwall and whitewall versions.
What does 650-16 mean on a 1934 Reo tire?
On a 1934 Reo tire, 650-16 is a numeric bias-ply size. The 6.50 figure refers to the tire's nominal section width in inches, and the 16 identifies the wheel diameter in inches. For 1934 Reo applications, that size appears on the Flying Cloud and is offered in traditional bias-ply construction, which is the period-correct type for a prewar American passenger car.
That code matters because it tells you both the basic width class and the wheel diameter the tire is built to fit. A 650-16 tire belongs on a 16-inch wheel, not an 18-inch wheel, and it should be matched against the wheel width requirements of the specific product you select. If your Flying Cloud already has tires mounted, comparing the sidewall marking on the car to the wheel diameter and the available rim-width range is a sensible way to confirm you are researching the correct fitment.
Do all 1934 Reo models use the same tire size?
No, 1934 Reo models do not use the same tire size. The Flying Cloud is associated with two 16-inch numeric bias-ply sizes, 650-16 and 700-16, while the Royale uses 650-18 on an 18-inch wheel. That means there is no one-size-fits-all tire for every 1934 Reo passenger car.
A buyer who starts with only the year and make can narrow the search quickly by confirming the model name on the car and measuring wheel diameter if needed. The Royale's 18-inch fitment separates it immediately from the Flying Cloud, while Flying Cloud owners need to sort out which of the two 16-inch sizes matches their car. Once that is settled, the remaining choices are mostly about sidewall appearance and brand preference within the correct size.
Buying the Right Tire
Should I choose the 650-16 or the 700-16 for my 1934 Reo?
A 1934 Reo owner should choose between 650-16 and 700-16 only if the car is a Flying Cloud, because both sizes are Flying Cloud fitments and both are bias-ply. The difference is not a modern-versus-vintage construction decision; it is a size decision within the same general prewar tire type. Both mount on 16-inch wheels, but available products show slightly different published rim-width ranges and load figures depending on the specific tire.
The practical way to decide is to identify what is already on the car, verify the wheel width, and consider the visual stance you are trying to maintain on the restoration. If your car is a Royale, neither of those sizes applies, so the right move is to shift immediately to 650-18. Staying within the size tied to your exact model avoids guesswork and keeps the appearance and proportions closer to what a 1934 Reo should carry.
What sidewall styles are available for 1934 Reo tires?
1934 Reo tires are available in both blackwall and wide whitewall styles across the listed sizes. The 650-16 Flying Cloud fitment appears in blackwall and wide whitewall versions from several brands, the 700-16 Flying Cloud fitment also spans blackwall and wide whitewall choices, and the 650-18 Royale fitment is offered in both blackwall and wide whitewall Firestone Balloon versions. That gives prewar Reo owners flexibility without moving away from bias-ply construction.
Sidewall style can change the car's visual character as much as the wheel itself. Blackwalls generally suit a more restrained or utilitarian presentation, while wide whitewalls better match the formal, upscale look many collectors want on 1930s American cars. For a judged restoration, the right choice depends on the exact way the car is being presented and the standards of the event or marque community, so it is wise to verify style expectations before finalizing a tire.
What brands make tires for 1934 Reo vehicles?
Several brands make tires for 1934 Reo vehicles, but the mix changes by size. The 650-16 Flying Cloud size is available from BFGoodrich, Coker Classic, Firestone, and Garfield. The 700-16 Flying Cloud size is available from Lester, Avon, BFGoodrich, and Firestone. The 650-18 Royale size is represented by Firestone.
That brand spread gives buyers room to prioritize a certain tread presentation, sidewall look, or series identity while staying within the correct size. It also means that one size may offer many more visual and brand combinations than another, especially on the Flying Cloud's 16-inch fitments. Comparing within the correct size first, then narrowing by sidewall style and published wheel requirements, is usually the cleanest way to sort the available options for a 1934 Reo.
Fitting & Setup
What rim width do 1934 Reo tires require?
Rim width requirements for 1934 Reo tires vary by size and by the specific products that publish that information. In 650-16, published examples call for 4.50 to 5.00-inch rims. In 700-16, published examples call for 4.50 to 5.50-inch rims. In 650-18, published products call for 3.25 to 3.50-inch rims. All of those dimensions should be matched to the exact tire you intend to fit.
Wheel diameter alone is not enough when setting up a prewar car. A 16-inch wheel can still be wrong for a given tire if its width falls outside the manufacturer's approved range, and that can affect the mounted tire's shape and behavior. Before fitting a 1934 Reo tire, confirm the wheel width directly on the car and compare it against the specifications for the exact brand and series you are considering.
Do 1934 Reo tires require inner tubes?
1934 Reo tire products are listed as traditional bias-ply fitments, but the individual product markings shown here do not consistently call out tube-type or tubeless status in the size line. On a prewar vehicle of this era, tube use is commonly part of the overall wheel-and-tire setup, especially with original-style wheels, and the exact requirement should be matched to the tire's sidewall marking and the wheel design being used.
The safest approach is to treat tube selection as part of the full installation plan instead of an afterthought. Verify the wheel type on your 1934 Reo, inspect its condition, and confirm the exact tire's sidewall designation before mounting. That is particularly important on cars that still run original wheels, because a tire that physically matches the diameter and width still needs to be paired correctly with the wheel's construction and sealing characteristics.
Can the original 1934 Reo wheels be used with both tire sizes on the Flying Cloud?
The two Flying Cloud sizes, 650-16 and 700-16, both mount on 16-inch wheels, so they share the same basic wheel diameter. Published product specifications show 650-16 examples on 4.50 to 5.00-inch rims and 700-16 examples on 4.50 to 5.50-inch rims, which means there is overlap but not automatic interchangeability across every wheel and every tire.
A Flying Cloud owner should verify the actual wheel width before assuming either size can be used on the existing wheels. If the wheels fall within the approved range for the specific tire you want, the diameter side of the equation is already correct. If the wheel width is borderline, choose the tire that matches the wheel rather than forcing the issue, since prewar chassis and body proportions look and behave best when the tire is mounted on an appropriate rim.
Maintenance, Storage & Longevity
How should I store a 1934 Reo when the tires are fitted?
A 1934 Reo should be stored in a cool, dry, dark space away from direct sunlight, electric motors, furnaces, welders, and other ozone-producing equipment that can age rubber. Keep the tires at operating pressure, avoid parking on damp earth, and move the car periodically or support it appropriately during very long storage periods. Bias-ply tires can flat-spot more readily during long static storage than later radial designs, so they benefit from occasional repositioning.
Storage habits have a direct effect on how a collector car feels the next time it goes out on the road. Even if a 1934 Reo is driven only occasionally, sunlight, ozone, and prolonged loading in one spot can age the casing and sidewalls faster than mileage would suggest. A simple routine of pressure checks, dry storage, and occasional movement helps preserve both blackwall and whitewall tires and reduces unpleasant surprises at the start of the driving season.
How long do tires on a 1934 Reo typically last?
Tires on a 1934 Reo usually age out before they wear out, because collector cars often see limited annual mileage. A good rule is to evaluate them closely once they reach the five-to-seven-year range and to treat around ten years as a serious replacement point regardless of tread depth. The DOT date code on the tire tells you its age, and age matters even when the car has spent most of its life indoors.
A bias-ply tire can still look presentable while the rubber and casing have lost the resilience needed for confident road use. Whitewalls may also cosmetically distract from age-related issues if a buyer is focused only on appearance. When assessing a 1934 Reo, use age, storage history, and physical condition together rather than relying on tread depth alone. That gives you a more realistic picture of whether the tires are still suitable for touring, local driving, or display-only use.
How often should tires on a 1934 Reo be inspected?
Tires on a 1934 Reo should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, embedded debris, and any sign that the tire is losing pressure. Because prewar cars often retain older-style hardware and may use tube-based setups depending on wheel and tire choice, the valve stems and spare should be part of the inspection routine as well.
Frequent inspection matters on a collector car because long gaps between drives can hide problems until the first miles of the day. A tire that held pressure in storage may still show cracks or casing changes once the car is moved into the light and driven at speed. Building a short walk-around into every outing helps catch age-related issues early and is one of the simplest ways to keep a 1934 Reo enjoyable on the road.
Restoration & Authenticity
What tires were originally fitted to the 1934 Reo Flying Cloud?
A 1934 Reo Flying Cloud would originally have been fitted with bias-ply tires, because bias-ply construction was standard practice for American passenger cars of the period. The available Flying Cloud sizes here are 650-16 and 700-16, both in bias-ply form and both aligned with the kind of tire construction expected on a mid-1930s Reo. No original-equipment brand should be assumed without checking period factory literature or marque-specific references.
For most restorers, the key authenticity points are the correct size, the correct bias-ply construction, and a sidewall style that matches the intended presentation of the car. If the car is being prepared for judged competition, details such as blackwall versus wide whitewall can matter as much as the size itself. A Reo club, factory sales material, or period photography can help settle those finer points for a specific body style or market presentation.
Does correct tire fitment matter for showing a 1934 Reo?
Correct tire fitment does matter when showing a 1934 Reo, especially in preservation and concours-oriented settings where judges and knowledgeable enthusiasts look closely at the overall stance and period accuracy of the car. On a prewar automobile, the size, bias-ply construction, and sidewall style all contribute to whether the car looks historically right. A mismatched wheel diameter or visibly modern tire type can stand out quickly on a 1930s body.
That does not mean every show uses the same standards, but it does mean tire choices should be made with the event's expectations in mind. A touring-focused car may prioritize durability and appearance within the correct size, while a judged car may need stricter adherence to the original-style construction and sidewall presentation. Before finalizing tires for a 1934 Reo show car, confirm the event rules and compare them with marque-club guidance so the car is judged in context.
What tires were originally fitted to the 1934 Reo Royale?
A 1934 Reo Royale would have used bias-ply tires as original-era equipment, consistent with luxury and near-luxury American cars of the mid-1930s. The fitment shown here for the Royale is 650-18, and the available products in that size are Firestone Balloon bias-ply tires in blackwall and wide whitewall forms. That combination matches the general construction type and visual language expected on a formal prewar car.
Royale owners restoring for authenticity should focus first on the 18-inch wheel requirement, then decide which sidewall treatment best matches the car's presentation. Because the Royale was positioned as a more upscale Reo, whitewall styling can be visually appropriate, but event rules and period references should guide the final call. If you are aiming for historical accuracy down to market-specific details, use the tire size as the foundation and verify the sidewall treatment through Reo reference material.
Safety & Road Use
Are 1934 Reo tires safe for highway driving?
1934 Reo tires can be suitable for highway driving when they are the correct size, in sound condition, and used within their published limits. The listed fitments are bias-ply tires, and one 700-16 Avon product carries an L speed rating, which corresponds to a 75 mph ceiling. Other products shown here do not display a speed letter in the size line, so highway use should be approached with the conservative expectations appropriate to a prewar bias-ply tire and a 1934 automobile overall.
On a car like a 1934 Reo, the bigger real-world limit is often the vehicle itself rather than the tire alone. Steering response, braking capability, suspension condition, and road crown sensitivity all shape how comfortable the car will feel at modern traffic speeds. Safe highway use starts with fresh tires, correct inflation, and a fully sorted chassis, then continues with sensible cruising speeds that respect both the tire construction and the era of the vehicle.
What inflation pressure should I use for 1934 Reo tires?
Inflation pressure on 1934 Reo tires should be set with both the vehicle's factory guidance and the tire maker's published limits in mind. Load-marked examples in 650-16 show 1580 pounds at 32 psi, 700-16 examples show figures including 1800 pounds at 36 psi and 1900 pounds at 36 psi, and a 650-18 example shows 1205 pounds at 36 psi. Those figures are tire ratings, not a blanket instruction to run every 1934 Reo tire at the same pressure.
The best approach is to begin with the owner's manual or authentic service literature for the car, then compare that target against the specifications for the exact tire you plan to fit. Pressure should never be borrowed from another size just because the car is from the same year. Once the tires are mounted, monitor wear and ride behavior carefully, since a prewar chassis can be noticeably affected by even small pressure changes.
What should I check before taking a 1934 Reo on a longer drive?
Before taking a 1934 Reo on a longer drive, inspect each tire for sidewall cracking, tread separation, cuts, bulges, and uneven wear, then confirm cold inflation pressure and check that the spare is usable. Look closely at valve stems and wheel condition, especially if the car uses an original-style wheel setup. Tires are only one part of the preparation, but on a prewar car they deserve special attention because age-related issues can develop even when the car has been driven very little.
A longer trip is also the right moment to think beyond the tires themselves. Confirm that brakes, wheel bearings, steering, cooling, and charging systems are ready for sustained use, because a sound tire cannot compensate for a marginal chassis. For the tire portion of the checklist, consistency is the goal: all four tires should match the intended size for the model, hold pressure evenly, and show no signs that storage or age has compromised the casing.
