The 1929 Reo Flying Cloud comes from an era when American manufacturers were blending advanced styling with the ride and road manners buyers expected from late-1920s touring cars. For owners restoring or maintaining one today, tire selection is closely tied to preserving that prewar look while matching the exact sub-model fitment. This Reo Flying Cloud uses bias-ply tires, with fitment centered around 30X6.20 and 650-18 for the Mas. 6 Cyl. and 30X6.00 and 6.00-18 for the Mte 6 Cyl. Available choices include traditional blackwall and wide whitewall presentations in Firestone Balloon form. The key decision is confirming the correct sub-model and then choosing the tire appearance that suits restoration goals and road use.
Which Tire Size Is Right for The 1929 Reo Flying Cloud
The 1929 Reo Flying Cloud uses four primary tire sizes, and the right one depends first on identifying the exact sub-model. All of these fitments are bias-ply and center on 18-inch wheel applications, but the Mas. 6 Cyl. and Mte 6 Cyl. do not use the same size pair. Once the correct sub-model is confirmed, the next step is choosing the tire style that matches the car's appearance and intended use.
30X6.20 is an antique diameter-by-section size, meaning the first number refers to an approximate 30-inch overall tire diameter and the second refers to an approximate 6.20-inch section width. It is a bias-ply fitment suited to the prewar tire construction and visual character expected on a 1929 Reo Flying Cloud Mas. 6 Cyl. This format is especially relevant to owners trying to keep an authentic late-1920s tire profile and presentation. It is important to confirm the exact Mas. 6 Cyl. setup and wheel before selecting among available period-style replacements in this sizing family.
650-18 is a numeric bias-ply size in which 650 indicates an approximate 6.50-inch nominal section width and 18 identifies the wheel diameter in inches. On the 1929 Reo Flying Cloud Mas. 6 Cyl., this size offers a more familiar vintage sizing convention for buyers comparing prewar replacement tires. Firestone Balloon options are available in this size, including blackwall and 3.50-inch wide whitewall versions. That makes 650-18 a strong fitment to evaluate when the goal is matching both the car's required size and its restoration-oriented sidewall appearance.
30X6.00 is an antique diameter-by-section size that identifies an approximate 30-inch tire diameter with an approximate 6.00-inch section width. It is a bias-ply fitment used on the 1929 Reo Flying Cloud Mte 6 Cyl., making it part of a distinct sub-model-specific tire pairing rather than a shared size across the whole model line. This older sizing language can look unusual to modern buyers, but it reflects the way many late-1920s tires were designated. Choosing this size begins with confirming that the car is the Mte 6 Cyl. and still uses the proper wheel setup.
6.00-18 is a numeric bias-ply size in which 6.00 represents the nominal section width in inches and 18 is the wheel diameter. On the 1929 Reo Flying Cloud Mte 6 Cyl., it serves as the numeric-format companion to 30X6.00 and keeps the tire choice aligned with traditional prewar construction. Buyers looking at this size should focus on maintaining proper visual proportion, wheel compatibility, and the car's intended driving use. It is especially important on older vehicles to verify the actual wheel diameter and overall setup before moving from size identification to tire selection.
Sub-model fitment matters on the 1929 Reo Flying Cloud because the covered configurations do not share the same tire sizes. Confirming whether the car is a Mas. 6 Cyl. or Mte 6 Cyl. is the first step before comparing tire format, appearance, or restoration priorities.

Tire Size & Fitment
What tire size fits a 1929 Reo Flying Cloud?
The 1929 Reo Flying Cloud does not use one universal tire size across all covered sub-models. The Mas. 6 Cyl. uses 30X6.20 and 650-18, while the Mte 6 Cyl. uses 30X6.00 and 6.00-18. All of these are bias-ply fitments associated with 18-inch applications.
The practical step is identifying the exact sub-model before choosing a tire. Antique diameter-by-section sizes and numeric bias-ply sizes can describe similar period fitment in different ways, so the wheel diameter and the car's current wheel setup should be checked carefully, especially if the vehicle has been restored, modified, or pieced together over time.
What size rim does a 1929 Reo Flying Cloud use?
The covered 1929 Reo Flying Cloud fitments use an 18-inch rim diameter. That applies to the numeric bias-ply sizes 650-18 and 6.00-18, and the overall fitment group for this model line centers on the same 18-inch wheel diameter.
Rim diameter is only part of the fitment picture on a prewar car. Wheel width, condition, and actual installed wheels should still be confirmed before mounting new tires, particularly when the car has older replacement wheels or restoration work of uncertain age. That extra check helps avoid mismatching a proper tire size to the wrong wheel.
Do all 1929 Reo Flying Cloud sub-models use the same tire size?
No. The 1929 Reo Flying Cloud Mas. 6 Cyl. uses 30X6.20 and 650-18, while the 1929 Reo Flying Cloud Mte 6 Cyl. uses 30X6.00 and 6.00-18. Both sub-models use bias-ply tires, but the sizes are not the same across the two covered configurations.
That difference matters because small changes in vintage tire width and sizing convention can affect the car's stance, appearance, and wheel match. A buyer should confirm the exact sub-model designation and inspect the wheels already on the car before selecting a tire, rather than assuming any late-1920s Reo Flying Cloud tire will suit every version.
Choosing the Right Tire
What should I consider when choosing a 650-18 tire for a 1929 Reo Flying Cloud?
For a 1929 Reo Flying Cloud that uses 650-18, the first priorities are confirming that the car is the Mas. 6 Cyl. configuration and staying with a bias-ply tire. In this size, available choices center on the Firestone Balloon series, so the decision becomes more about appearance and wheel compatibility than switching among very different constructions.
The most visible choice is sidewall style, since 650-18 is available in both blackwall and 3.50-inch wide whitewall form. Rim width should also be checked against the wheel on the car, and owners should think about whether the goal is a traditional touring-car presentation, a restoration-focused look, or regular but careful collector-vehicle road use.
What sidewall styles are available for 1929 Reo Flying Cloud tires?
For the 1929 Reo Flying Cloud products available in 650-18, the sidewall choices are blackwall and wide whitewall. Both are offered within the Firestone Balloon line, which keeps the size and bias-ply construction consistent while changing the visual presentation of the tire.
That appearance choice can strongly influence how a late-1920s car looks at a glance. A blackwall gives a simpler, more understated presentation, while a wide whitewall creates a more formal period-style look. The right choice depends on how the car is being restored, the trim and paint combination, and whether visual authenticity or personal preference matters more.
What brands offer tires for the 1929 Reo Flying Cloud?
The available 650-18 tire options for the 1929 Reo Flying Cloud come from Firestone. Those products are part of the Firestone Balloon series and keep the fitment focused on traditional bias-ply construction for this prewar application.
Because the available products in this fitment are concentrated within one brand and one series, selection is less about comparing multiple manufacturers and more about comparing details such as sidewall style, load specification where stated, and wheel compatibility. On a car of this age, the exact size and proper wheel match usually matter more than chasing brand variety.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Reo Flying Cloud?
A period-style 1929 Reo Flying Cloud should stay with the correct sub-model-specific bias-ply size before anything else. That means 30X6.20 or 650-18 for the Mas. 6 Cyl., and 30X6.00 or 6.00-18 for the Mte 6 Cyl. The period look starts with proper size, overall proportion, and traditional construction.
Once the fitment is confirmed, the appearance decision usually comes down to sidewall treatment and how formal or understated the finished car should look. Owners pursuing exact historical accuracy should compare the finished tire choice with marque references, period photos, or restoration documentation, since a correct size alone does not automatically settle every appearance detail.
Does correct tire fitment matter for a 1929 Reo Flying Cloud restoration?
Yes, correct tire fitment matters a great deal on a 1929 Reo Flying Cloud restoration. The right sub-model-specific size affects the car's proportions, wheel relationship, and the overall visual balance that makes a late-1920s automobile look settled and convincing.
Using the wrong size can change the way the car sits and can make an otherwise careful restoration look slightly off. Correct fitment also helps avoid practical issues with wheel compatibility and serviceability. Even when the goal is mainly show presentation, tire choice deserves the same attention given to paint, trim, and other visible restoration details.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Reo Flying Cloud?
Yes. Modifications can affect tire fitment on a 1929 Reo Flying Cloud even when the tire size itself is correct. Different wheels, altered suspension height, brake conversions, or body and fender changes can influence how much space the tire has and whether the wheel remains compatible with a vintage bias-ply fitment.
A prewar car may also have replacement parts installed decades ago, so the current setup should not be assumed to match original dimensions. Measuring the actual wheel diameter and width, then checking steering and fender clearance at rest and through movement, helps prevent costly mistakes before mounting new tires or putting the car back on the road.
What should I inspect before driving a 1929 Reo Flying Cloud on new tires?
Before driving a 1929 Reo Flying Cloud on new tires, inspect the wheels, valve hardware, and the overall condition of the suspension and steering components. The tires should be mounted in the correct sub-model-specific size, and the wheels should be checked for damage, corrosion, poor seating surfaces, or age-related issues that can affect serviceability.
A short road test is best done only after confirming proper inflation, visual clearance, and even seating of each tire. It also helps to recheck fasteners, look for signs of rubbing, and monitor air retention after the first drive. On collector vehicles, small issues often show up during the first few miles rather than while sitting in storage.
How should 650-18 tires on a collector 1929 Reo Flying Cloud be maintained?
650-18 tires on a collector 1929 Reo Flying Cloud should be maintained with regular pressure checks, visual inspection, and careful storage habits. Bias-ply tires on older collector cars benefit from routine examination for cracking, bulges, cuts, irregular wear, and air loss, especially when the vehicle is driven infrequently.
Storage conditions matter almost as much as mileage on a low-use prewar car. Keeping the vehicle away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives. It is also wise to inspect the wheels and valve areas periodically, since a tire can only perform as well as the wheel and mounting hardware beneath it.
