The 1927 Stutz 8 Cyl. came from an era when American prestige cars were expected to combine speed, road presence, and long-distance stamina. Stutz built its reputation around advanced engineering and performance-minded luxury, which makes tire selection especially important for a car that is often restored for touring as much as display. This model uses bias-ply tire fitments in 32X6.20 and 650-20 on 20-inch wheels. That gives owners a choice between period-style blackwall, wide whitewall, and classic truck-oriented tread offerings within the proper size family. The real decision is matching the car’s existing wheel setup and restoration goals to the right bias-ply presentation.
Which Tire Size Is Right for The 1927 Stutz 8 Cyl.
The 1927 Stutz 8 Cyl. uses two primary tire sizes, and both are bias-ply fitments tied to a 20-inch wheel. Because the Base sub-model can use either 32X6.20 or 650-20, the first step is confirming which size is on the car now and making sure the wheel dimensions match before choosing a replacement.
32X6.20 is an antique diameter-by-section size, meaning the first number refers to an approximate overall tire diameter of 32 inches and the second refers to a nominal section width of about 6.20 inches. It is a bias-ply fitment, which suits the driving feel and visual character expected on a late-1920s luxury and performance car. This format is especially relevant to restoration-minded owners who want to stay close to an early tire-sizing convention. Before selecting this size, confirm that the car is actually set up for 32X6.20 rather than the alternate 650-20 fitment.
650-20 is a numeric bias-ply size in which the 650 indicates a nominal section width of roughly 6.50 inches and the 20 identifies the wheel diameter in inches. For the 1927 Stutz 8 Cyl., this size opens up the widest product choice, including Firestone, Denman, and Deka offerings in blackwall, wide whitewall, and classic truck-style series. Some versions also include published rim-width and load information that can help narrow the field. It is the practical choice when the car already wears 20-inch wheels set up for 650-20 tires.
Sub-model fitment is straightforward here because the covered 1927 Stutz 8 Cyl. Base can use the same two primary tire sizes. The important step is not trim identification so much as confirming which wheel and tire size the car is actually carrying before replacement.

1927 Stutz 8 Cyl. Base
The 1927 Stutz 8 Cyl. Base uses bias-ply tire fitments in both 32X6.20 and 650-20. That means tire selection depends on confirming the wheel and existing size on the car, then choosing the sidewall style and tire series that best suit a restoration-oriented or road-use plan.
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.

Available 650-20 choices for the 1927 Stutz 8 Cyl. include Firestone, Denman, and Deka bias-ply tires across blackwall and wide whitewall styles. The product grid is where to compare classic passenger-style and truck-oriented series, along with rim-width, weight, and load details where published.
Owners of a 1927 Stutz 8 Cyl. usually need clarity on the difference between 32X6.20 and 650-20, how 20-inch wheel fitment affects tire choice, and how sidewall style, restoration goals, and road-use checks shape the final decision.
Tire Size & Fitment
What tire size fits a 1927 Stutz 8 Cyl.?
The 1927 Stutz 8 Cyl. uses two primary bias-ply tire sizes: 32X6.20 and 650-20. Both sizes are associated with the 1927 Stutz 8 Cyl. Base, so the correct replacement depends on which wheel and tire setup is actually on the car rather than assuming one size applies to every example.
That makes inspection especially important before ordering tires. Check the size marked on the existing tires, confirm the wheel diameter is 20 inches, and make sure the wheel is appropriate for the size you plan to run. Older collector cars are often changed over time, so the car’s current setup matters more than assumption.
What size rim does a 1927 Stutz 8 Cyl. use?
The 1927 Stutz 8 Cyl. uses a 20-inch rim diameter with its primary tire fitments. The 650-20 size clearly corresponds to a 20-inch wheel, and the overall fitment picture for this model centers on 20-inch rims rather than multiple wheel diameters.
Rim diameter is only one part of the fitment check on a car of this age. The wheel’s width, condition, and actual construction should also be reviewed before mounting new bias-ply tires. A collector vehicle that has had wheel changes over the years may need a closer inspection to confirm the intended tire size still matches the hardware.
Why does the 1927 Stutz 8 Cyl. have more than one tire size?
The 1927 Stutz 8 Cyl. can use both 32X6.20 and 650-20, which reflects two different vintage sizing conventions within the same general fitment range. One is an antique diameter-by-section format, while the other is a numeric bias-ply size, and both are tied to bias-ply construction for this vehicle.
For an owner, the practical takeaway is to verify the car’s actual wheel and tire setup instead of choosing by size name alone. Cars from the 1920s are often restored or updated at different times, and one Stutz may not be wearing the same size as another. Confirm the wheel, compare the current tire markings, and then choose accordingly.
Choosing the Right Tire
What should I consider when choosing a 650-20 tire for a 1927 Stutz 8 Cyl.?
Start with the basics: confirm that 650-20 is the size the car is actually using, then compare bias-ply construction, sidewall style, and tire series. Available 650-20 options include Firestone, Denman, and Deka, with choices ranging from blackwall and wide whitewall to classic truck-oriented tread designs.
The right choice depends on how the Stutz is used and presented. A restoration-focused car may call for a more formal sidewall treatment, while a road-driven car may lead you toward a particular tread style or published rim-width specification. Looking at weight and load details where available can also help narrow the selection responsibly.
What sidewall styles are available for 1927 Stutz 8 Cyl. tires?
For the 1927 Stutz 8 Cyl., the available 650-20 product range includes blackwall and wide whitewall sidewall styles. That gives owners a meaningful appearance choice within the correct bias-ply size family, especially when balancing a formal restoration look against a more understated period-style presentation.
Sidewall style changes the visual impression of the car even when the tire size stays the same. A wide whitewall tends to stand out more on a restored luxury-era automobile, while a blackwall keeps the look simpler and more utilitarian. Appearance should still be matched with the right size, wheel compatibility, and intended driving use.
What brands offer tires for the 1927 Stutz 8 Cyl.?
The 650-20 fitment for the 1927 Stutz 8 Cyl. is available from Firestone, Denman, and Deka. Those offerings span Firestone Classic Bias Ply, Firestone Classic Truck, Highway Classic Truck, and Deka Classic Truck series, giving owners several period-style options within the same core size range.
Brand choice should be considered alongside the tire’s overall character rather than by name alone. Some options lean toward a more traditional passenger-car presentation, while others have a truck-oriented style and specification set. Comparing sidewall treatment, published rim-width guidance, and any stated load information will usually be more useful than focusing on brand by itself.
Restoration & Appearance
Which tire should I choose for a period-style 1927 Stutz 8 Cyl.?
A period-style 1927 Stutz 8 Cyl. should start with one of its proper bias-ply fitments, either 32X6.20 or 650-20, depending on the wheel and tire setup already on the car. Keeping the correct vintage construction is usually the first step toward preserving the car’s visual character and era-appropriate stance.
From there, the decision shifts to presentation. A blackwall gives a more restrained look, while a wide whitewall adds a more formal restoration-oriented appearance. Since exact originality can vary by body, wheel, and surviving documentation, owners pursuing a highly exact restoration should compare tire choices against marque references and historical records for their specific car.
Does correct tire fitment matter for a 1927 Stutz 8 Cyl. restoration?
Yes, correct tire fitment matters on a 1927 Stutz 8 Cyl. because the tire has a major effect on the car’s proportions, stance, and overall period impression. Using one of the proper bias-ply size families, rather than an arbitrary substitute, helps keep the finished car visually consistent with its late-1920s character.
Fitment also affects how the restoration comes together mechanically. The right wheel diameter and compatible tire size reduce the chance of avoidable clearance or mounting issues, and they make the car look more settled and intentional. Even when the goal is mainly appearance, checking the actual wheel setup before final selection is an important restoration step.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1927 Stutz 8 Cyl.?
Yes, modifications can affect tire fitment on a 1927 Stutz 8 Cyl., even when the intended size is 32X6.20 or 650-20. Changes to wheels, wheel width, offset, suspension height, brake hardware, or body clearances can alter how a vintage bias-ply tire sits and moves within the available space.
A Stutz that has been restored over many decades may not still be in its original wheel configuration. Checking clearance at full steering lock, verifying wheel diameter, and measuring the actual wheel before mounting tires can prevent expensive mistakes. Even small changes in an older chassis can matter once the new tire is installed and the car is loaded.
What should I inspect before driving a 1927 Stutz 8 Cyl. on new tires?
Before driving a 1927 Stutz 8 Cyl. on new tires, inspect the wheels for condition and correctness, confirm the tires are mounted in the intended size, and make sure inflation matches the tire’s needs. It also helps to look over the suspension, steering components, and brake system on a car from this era.
Collector vehicles often spend long periods parked, so a fresh tire installation is a good time to recheck the whole running setup. Watch for rubbing at turns, uneven stance, visible air loss, or any sign of wheel or bead issues after the first short drive. A careful initial inspection makes later road use much more predictable.
How should 650-20 tires on a collector 1927 Stutz 8 Cyl. be maintained?
650-20 tires on a collector 1927 Stutz 8 Cyl. should be maintained with regular pressure checks, visual inspections, and careful storage habits. Look for sidewall cracking, cuts, bulges, uneven wear, or signs of air loss, especially on a car that is driven infrequently and may spend long periods parked.
Storage conditions matter nearly as much as mileage on a vintage car. Keeping the Stutz away from prolonged sunlight, excess heat, moisture, and ozone sources can help protect the tires between drives. It is also wise to inspect the tires before each outing rather than relying on appearance alone, since age-related issues can develop even with light use.
