The 1927 Roamer 88 Series came from an era when American cars still carried a strong handcrafted presence, with substantial proportions and upscale touring character that set them apart from lighter, more common automobiles of the day. Tire choice on a vehicle like this affects not only road manners, but also stance and visual authenticity. The 1927 Roamer 88 Series uses bias-ply fitments in 32X6.20 and 650-20 on 20-inch wheels, so the first step is confirming which of those period sizes is on the car. Available choices include blackwall and wide whitewall presentations, along with passenger-style and truck-oriented series. That makes fitment, appearance, and intended driving use equally important when selecting a replacement.
Which Tire Size Is Right for The 1927 Roamer 88 Series
The 1927 Roamer 88 Series uses two primary tire sizes, and both are bias-ply fitments tied to 20-inch wheels. Because the covered 8 Cyl. sub-model can be found with either size, the key step is confirming the exact tire size already on the car and checking wheel dimensions before choosing between period-style passenger and truck-oriented replacement options.
32X6.20 is an antique diameter-by-section size, meaning the first number refers to the tire's approximate overall diameter and the second refers to its nominal section width. On a 1927 Roamer 88 Series, it represents an early-period bias-ply fitment suited to the proportions and visual character expected on a large late-1920s automobile. This format appeals to owners focused on maintaining an authentic prewar look rather than moving to a later sizing system. Before selecting it, confirm that the car is actually set up for this antique-format size and that wheel dimensions match the tire's intended application.
650-20 is a numeric bias-ply size in which 6.50 indicates the nominal section width in inches and 20 indicates the rim diameter. For the 1927 Roamer 88 Series, this size opens up several useful choices, including Firestone, Denman, and Deka offerings, with blackwall and wide whitewall sidewall styles and both passenger-style and truck-oriented series. Some versions also carry stated rim-width and load specifications that help narrow the field. It is a practical size to evaluate when balancing visual presentation, wheel compatibility, and the kind of driving the car is expected to see.
Sub-model fitment is straightforward here, but tire selection still requires attention because the covered Roamer 88 Series configuration can use more than one period tire size. Checking the exact sub-model and the wheels currently on the car helps prevent choosing the wrong early-size format.

1927 Roamer 88 Series 8 Cyl.
The 1927 Roamer 88 Series 8 Cyl. uses two bias-ply tire sizes, 32X6.20 and 650-20, both associated with 20-inch wheel fitment. That means selection starts with confirming which size system the car currently carries, then deciding whether appearance, load-oriented construction, or whitewall versus blackwall presentation matters most.
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.

Common questions for the 1927 Roamer 88 Series usually center on the difference between 32X6.20 and 650-20, 20-inch wheel fitment, sidewall appearance, and what to inspect before putting a seldom-driven vintage car back on the road.
Tire Size & Fitment
What tire size fits a 1927 Roamer 88 Series?
The 1927 Roamer 88 Series uses two primary bias-ply tire sizes: 32X6.20 and 650-20. Both are associated with 20-inch wheel fitment, and the covered 8 Cyl. configuration can be found with either size depending on how the car is equipped.
That makes the first job simple but important: verify the size currently on the vehicle before ordering a replacement. Antique-format 32X6.20 and numeric 650-20 are not just different labels for the same tire, so the wheel setup and the size already in service should be checked carefully.
What size rim does a 1927 Roamer 88 Series use?
The 1927 Roamer 88 Series uses a 20-inch rim diameter. That rim diameter aligns with the 650-20 numeric bias-ply fitment, and the vehicle's other primary size options also center around 20-inch wheel use.
Rim diameter is only part of the fitment picture on a late-1920s car. Wheel width, tire bead style, and the actual size already mounted should all be confirmed before replacing tires, especially if the car has been restored, stored for years, or fitted with wheels that may not match its earlier specification.
Does the 1927 Roamer 88 Series 8 Cyl. use the same tire size?
The 1927 Roamer 88 Series 8 Cyl. does not narrow the fitment to just one size. It can use either 32X6.20 or 650-20, both in bias-ply construction, so the sub-model name alone does not settle the tire decision.
That means the tire already on the car and the wheel dimensions matter more than the sub-model label by itself. A buyer should inspect the sidewall markings, confirm the wheel diameter, and make sure the replacement size matches the vehicle's current setup rather than assuming every 8 Cyl. car is identical.
Choosing the Right Tire
What should I consider when choosing a 650-20 tire for a 1927 Roamer 88 Series?
Start with the correct size, construction, and wheel compatibility. A 650-20 for the 1927 Roamer 88 Series should match the vehicle's 20-inch wheel setup, and then the choice shifts to the type of bias-ply tire that best suits the car's appearance and intended use.
Within 650-20, the available choices include blackwall and wide whitewall styles, along with passenger-style and truck-oriented series from Firestone, Denman, and Deka. Comparing rim-width specifications, load figures where stated, and the visual character of the sidewall helps narrow the selection without treating every 650-20 as the same.
What sidewall styles are available for 1927 Roamer 88 Series tires?
The available 650-20 products for a 1927 Roamer 88 Series include blackwall and wide whitewall sidewall styles. That gives the car owner a meaningful appearance choice even while staying within a period-style bias-ply fitment.
A blackwall usually creates a more restrained, utilitarian presentation, while a wide whitewall adds a stronger vintage luxury look. Because sidewall style can change the visual personality of the car so much, it is worth deciding whether the goal is formal touring appearance, understated originality, or a more road-use-oriented setup.
What brands offer tires for the 1927 Roamer 88 Series?
Available 650-20 tires for the 1927 Roamer 88 Series come from Firestone, Denman, and Deka. The product mix includes Firestone Classic Bias Ply, Firestone Classic Truck, Highway Classic Truck, and Deka Classic Truck series.
Brand alone should not decide the purchase on a car like this. It is smarter to compare the style of tire each brand offers, whether the sidewall is blackwall or wide whitewall, and whether the tire is more passenger-oriented or truck-oriented for the way the Roamer will actually be shown and driven.
Restoration & Appearance
Which tire should I choose for a period-style 1927 Roamer 88 Series?
A period-style 1927 Roamer 88 Series should begin with one of its correct primary bias-ply sizes, either 32X6.20 or 650-20, depending on the wheel and tire setup already on the car. Keeping the proper size format matters because late-1920s cars look noticeably different when the tire proportions are off.
Within 650-20, the appearance choice can then shift toward blackwall or wide whitewall, depending on the character you want the car to present. When exact restoration authenticity matters, it is wise to compare surviving photos, marque references, and restoration documentation before settling on a sidewall treatment or tire series.
Does correct tire fitment matter for a 1927 Roamer 88 Series restoration?
Correct tire fitment matters a great deal on a 1927 Roamer 88 Series because tire diameter, sidewall shape, and section width all influence how the car sits and how complete the restoration looks. On a large car from this era, the wrong size can make the proportions appear noticeably off.
Fitment also affects practical details such as wheel compatibility and body clearance, so appearance should not be separated from function. Even when the goal is a restoration-oriented presentation, the replacement tire still needs to match the wheel setup actually on the vehicle and the way the car will be used.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1927 Roamer 88 Series?
Yes, modifications can affect tire fitment on a 1927 Roamer 88 Series. Changes to wheels, hub components, suspension height, brake conversions, or body clearance can alter what size works properly, even when the car began life with 32X6.20 or 650-20 bias-ply tires.
A vintage car may also have replacement wheels installed decades ago, so the tire size on paper should not be the only guide. Checking actual rim diameter, wheel width, clearance at full steering lock, and the space around fenders and suspension parts helps avoid fitment problems before road use.
What should I inspect before driving a 1927 Roamer 88 Series on new tires?
Before driving a 1927 Roamer 88 Series on new tires, inspect the wheels, valve stems, lug hardware, and overall wheel condition, then confirm that the tires are mounted in the correct size and seated properly. It is also worth checking for any interference as the steering is turned through its full range.
A careful road-use check should continue with tire pressure, visible sidewall condition, tread area inspection, and a slow test drive to confirm that the car tracks cleanly. On a collector vehicle that may sit for long periods, examining brakes, wheel bearings, and suspension condition at the same time is equally sensible.
How should 650-20 tires on a collector 1927 Roamer 88 Series be maintained?
650-20 tires on a collector 1927 Roamer 88 Series should be kept properly inflated, inspected regularly for cracks, cuts, bulges, and air loss, and stored away from prolonged sunlight, heat, moisture, and ozone exposure. Collector cars often age their tires through time and storage rather than through heavy mileage.
Periodic checks matter even when the Roamer is driven only occasionally. Looking over tread condition, sidewalls, and valve stems before each outing helps catch age-related problems early, and moving the car from time to time can reduce long static loading on one section of the tire during storage.
