The 1927 Wills, Sainte Claire 8 Cyl. comes from a brief but fascinating chapter in American luxury-car history, when independent manufacturers competed on engineering presence as much as styling. A car of this era depends heavily on proper tall-profile tire fitment, both visually and mechanically, and this Wills Sainte Claire uses bias-ply sizing in 32X6.20 or 650-20 on 20-inch rims. That makes the decision less about modernizing and more about choosing the right period-style presentation, whether that means a traditional blackwall or a wide whitewall look. For restoration-minded owners, wheel dimensions, intended use, and authentic era character all matter before selecting a tire.
Which Tire Size Is Right for The 1927 Wills, Sainte Claire 8 Cyl.
The 1927 Wills, Sainte Claire 8 Cyl. uses two primary tire sizes, and both are bias-ply fitments associated with a 20-inch wheel setup. Since the Base sub-model can use either size, the main question is not trim level but which sizing convention matches the wheels already on the car and the kind of period-style tire presentation you want to preserve.
The 32X6.20 size uses an older diameter-by-section format, where 32 refers to the approximate overall tire diameter and 6.20 refers to nominal section width in inches. It is a bias-ply fitment suited to the tall, upright tire proportions expected on a late-1920s luxury automobile such as the Wills Sainte Claire. This format appeals to owners trying to keep an early-car look rather than moving to later numeric sizing conventions. It is worth comparing this size carefully against the wheel and the car's existing setup so the tire's visual profile and fitment remain in character with the vehicle.
The 650-20 size is a numeric bias-ply format in which 6.50 indicates nominal section width in inches and 20 identifies the rim diameter. On the 1927 Wills, Sainte Claire 8 Cyl., this size opens up the broadest visible choice in available tires, including Firestone, Denman, and Deka offerings, along with blackwall and wide whitewall presentations across classic bias-ply and truck-style series. That makes 650-20 especially useful for owners balancing restoration appearance, road use, and wheel compatibility. It is still important to confirm the wheel dimensions and overall vehicle setup before settling on one construction and style.
Fitment is straightforward here because the covered sub-model uses the same two primary bias-ply tire sizes. The real task is confirming which wheel and tire sizing convention is already on the car before choosing a replacement tire.

Tire Size & Fitment
What tire size fits a 1927 Wills, Sainte Claire 8 Cyl.?
The 1927 Wills, Sainte Claire 8 Cyl. uses two primary tire sizes: 32X6.20 and 650-20. Both are bias-ply fitments, and the Base sub-model can use either of those sizes rather than having a separate trim-specific tire requirement.
That makes the next step a wheel-and-setup check, not a trim-level check. On an antique car, the existing wheels, prior restoration choices, and the tire sizing system already used on the vehicle matter just as much as the year and model name, so it is smart to verify the wheel dimensions and current tire markings before replacing anything.
What size rim does a 1927 Wills, Sainte Claire 8 Cyl. use?
The 1927 Wills, Sainte Claire 8 Cyl. uses a 20-inch rim with its primary tire fitments. The numeric 650-20 size directly confirms that 20-inch rim diameter, and the vehicle's fitment centers around that wheel size.
On a collector car from the 1920s, rim diameter alone is only part of the picture. Wheel width, original versus replacement rims, and any long-ago changes made during restoration can affect which tire works best, so checking the actual wheel on the car is the safest way to narrow down the correct bias-ply replacement.
What does 32X6.20 mean on a 1927 Wills, Sainte Claire 8 Cyl.?
A 32X6.20 tire uses an antique diameter-by-section sizing format. In plain terms, 32 refers to the tire's approximate overall diameter in inches, while 6.20 refers to the nominal section width, making it a very different style of size designation from later numeric bias-ply markings.
That matters because older size formats often reflect the era of the wheel and the look of the car as much as the physical fitment. If a 1927 Wills, Sainte Claire 8 Cyl. is already wearing 32X6.20 tires, matching that format can help preserve the vehicle's traditional stance and appearance while keeping the replacement search focused.
Choosing the Right Tire
What should I consider when choosing a 650-20 tire for a 1927 Wills, Sainte Claire 8 Cyl.?
Start with the correct size, construction, and wheel compatibility. A 650-20 for the 1927 Wills, Sainte Claire 8 Cyl. is a bias-ply tire on a 20-inch rim, and the available choices vary by series, sidewall style, brand, load specification where stated, and intended visual character.
Appearance often drives the decision on a car from this era, but the wheel setup still comes first. Some 650-20 options are geared toward classic passenger-car presentation, while others lean toward truck-style tread and military or utility character, so compare the tire's look and specifications against how the car is restored and actually used.
What sidewall styles are available for 1927 Wills, Sainte Claire 8 Cyl. tires?
The available 650-20 tires for a 1927 Wills, Sainte Claire 8 Cyl. include blackwall and wide whitewall sidewall styles. That gives owners a meaningful appearance choice within the correct vintage bias-ply size rather than forcing a single visual treatment.
A blackwall usually creates a more restrained, utilitarian presentation, while a wide whitewall can bring a more formal restoration-oriented look to a late-1920s automobile. Since sidewall style changes the car's visual impression immediately, it helps to choose it alongside wheel finish, body color, and the overall direction of the restoration.
What brands offer tires for the 1927 Wills, Sainte Claire 8 Cyl.?
The 650-20 fitment for the 1927 Wills, Sainte Claire 8 Cyl. is available from Firestone, Denman, and Deka. Those choices span classic bias-ply passenger-style offerings and more truck-oriented series, so the brand name also reflects differences in tire character and presentation.
Brand should be considered alongside the actual product type, sidewall treatment, and wheel compatibility rather than by name alone. On a vehicle this old, the right choice often comes down to whether the tire's proportions and appearance suit a formal restoration, a touring car, or a more utility-minded setup already established on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1927 Wills, Sainte Claire 8 Cyl.?
A period-style choice for a 1927 Wills, Sainte Claire 8 Cyl. starts with retaining one of its correct bias-ply sizes, either 32X6.20 or 650-20. Within 650-20, the available options include classic bias-ply and truck-style series that let the owner stay within an era-appropriate construction type.
The best visual match depends on how the car has been restored and what look it already carries. Owners focused on exact historical presentation should compare tire details with marque literature, period photographs, or recognized restoration references, while others may simply want a tire that keeps the late-1920s stance and character intact.
Which sidewall style suits a period-style 1927 Wills, Sainte Claire 8 Cyl.?
Both blackwall and wide whitewall 650-20 tires can suit a period-style 1927 Wills, Sainte Claire 8 Cyl., depending on the presentation you want. Blackwall gives a more understated and practical look, while wide whitewall creates a dressier, more formal visual statement on a large late-1920s automobile.
The right answer usually comes from the car's broader restoration theme rather than from the tire alone. Body color, wheel finish, trim level of the restoration, and how the car is shown or driven all influence which sidewall looks right, so it helps to choose the tire as part of the complete exterior presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1927 Wills, Sainte Claire 8 Cyl.?
Yes. Even when a 1927 Wills, Sainte Claire 8 Cyl. uses the correct vintage tire size, fitment can change if the car has replacement wheels, altered wheel widths, brake updates, suspension work, or body and fender adjustments made during an older restoration.
That is especially important on antique vehicles because changes made decades ago are not always obvious at first glance. Measuring the actual wheel, checking current tire markings, and looking at steering and fender clearance before ordering helps avoid choosing a tire that matches the model name on paper but conflicts with the car's present setup.
What should I inspect before driving a 1927 Wills, Sainte Claire 8 Cyl. on new tires?
Check the wheels, valve stems, mounting hardware, and overall tire condition before road use, even with new tires installed. A 1927 Wills, Sainte Claire 8 Cyl. should also be inspected for proper inflation, even tread seating, obvious clearance issues, and any signs that the wheels themselves need attention.
Roadworthiness on a collector car depends on more than the tires alone. Steering components, suspension condition, brake operation, and the way the tire sits in the wheel opening all deserve a careful look, particularly after the car has been stored or recently returned to service after restoration work.
How should tires on a collector 1927 Wills, Sainte Claire 8 Cyl. be maintained?
Collector-car tires should be inspected regularly for air loss, cracking, cuts, bulges, and uneven wear, even if the 1927 Wills, Sainte Claire 8 Cyl. is driven only occasionally. Keeping the tires properly inflated and moving the car periodically can also help prevent long-term flat spotting during storage.
Storage conditions matter more than many owners expect. A cool, dry environment away from prolonged sunlight, moisture, and ozone sources helps preserve vintage-style tires, and any tire that shows age-related deterioration should be evaluated before road use, no matter how much tread remains on it.
