1927 Wills, Sainte Claire 6 Cyl. Tires

The 1927 Wills, Sainte Claire 6 Cyl. uses two primary tire sizes: 32X6.20 and 650-20. Both are bias-ply fitments, and the covered Base sub-model can use either size, which means this car does not come down to a single modern-style fitment answer.

The practical decision is confirming which wheel-and-tire combination is already on the car. A restored vehicle may have stayed with its long-time setup, and older collector cars are sometimes changed over the years. Checking the sidewall markings, the actual rim diameter, and the overall look you want before ordering helps avoid choosing the right era of tire in the wrong size.

The primary fitments for the 1927 Wills, Sainte Claire 6 Cyl. use a 20-inch rim. That rim diameter aligns with the 650-20 size and is the wheel diameter to confirm before selecting a replacement tire for the car.

Rim diameter is only part of the fitment picture on an older vehicle. It still helps to inspect the wheel itself for width, condition, and any prior changes, especially if the car has been restored over many decades. Matching the tire to the correct 20-inch wheel is the starting point, then the buyer can narrow the choice by size format, sidewall style, and intended use.

The 1927 Wills, Sainte Claire 6 Cyl. Base can use the same two primary tire sizes covered for this model: 32X6.20 and 650-20. Both are bias-ply fitments tied to the same 20-inch rim diameter, so the sub-model itself does not create a separate size split.

That makes the real task verifying which of those two sizes is mounted on the specific car. On a collector vehicle of this age, wheels and tires may have been changed long ago for appearance or availability. Looking at the tire sidewall, measuring the wheel, and comparing the car's present stance can clarify which size should guide the replacement choice.

Start with the basics: confirm that 650-20 is the size currently used on the car and that the wheel is a 20-inch rim. Then compare the available bias-ply choices by sidewall style, tire series, and intended character, since this size is offered in both classic passenger-style and truck-oriented versions.

Appearance matters on a car from this era, so a wide whitewall creates a very different presentation than a blackwall. It also helps to compare any stated rim-width specifications, load figures where shown, and the car's actual use. A lightly driven restoration, a tour car, and a display-focused vehicle may all point the buyer toward different choices within the same 650-20 size.

The available 650-20 choices for the 1927 Wills, Sainte Claire 6 Cyl. include blackwall and wide whitewall sidewall styles. That gives the car owner a meaningful appearance decision even while staying within the correct bias-ply sizing family for this vehicle.

A blackwall usually delivers a more restrained and utility-minded look, while a wide whitewall creates a stronger pre-war touring and luxury visual impression. Neither sidewall treatment should be assumed correct for every surviving car, so restoration-focused buyers often compare the tire choice against photos, marque references, or the vehicle's existing presentation before settling on a final look.

Available 650-20 tires for the 1927 Wills, Sainte Claire 6 Cyl. come from Firestone, Denman, and Deka. Those choices appear across classic bias-ply passenger lines and truck-oriented series, so the brand name alone does not tell the full story of how the tire will present on the car.

The smarter comparison is to look at the combination of brand, tire series, sidewall style, and any stated specifications such as rim-width compatibility or load capacity. A Firestone wide whitewall serves a different purpose than a blackwall truck-style casing, even though both fit the same nominal size. Matching the product character to the car matters more than chasing a brand name by itself.

A period-style approach for a 1927 Wills, Sainte Claire 6 Cyl. starts with the correct bias-ply construction and one of the two proper size families, 32X6.20 or 650-20. From there, the choice depends on how closely the owner wants to reflect the car's era in both size language and visual presentation.

The 32X6.20 format carries especially early sizing character, while 650-20 offers the broadest product selection in currently available tires. Sidewall treatment also shapes the result, with blackwall and wide whitewall creating very different appearances. Buyers pursuing strict historical accuracy should compare the tire choice with period photos, marque-club guidance, or other vehicle-specific documentation before finalizing the restoration look.

Tire construction has a major effect on the look of a restored 1927 Wills, Sainte Claire 6 Cyl. because bias-ply tires carry the tall, traditional profile and visual character expected on a late-1920s automobile. On this car, the primary fitments are bias-ply, so the construction itself is part of the vehicle's period-style presentation.

Beyond size alone, the sidewall and tread character influence whether the car reads as formal, touring-oriented, or more utilitarian. A wide whitewall can emphasize luxury-era styling, while blackwall choices can appear more restrained. Since restored collector cars often vary by prior ownership decisions, the best visual result comes from matching construction, size family, and sidewall treatment to the car's overall restoration direction.

Yes. Even though the 1927 Wills, Sainte Claire 6 Cyl. uses traditional 20-inch bias-ply fitments, later changes can alter what works on the individual car. Older collector vehicles are especially likely to have had wheel substitutions, suspension work, brake changes, or body adjustments over the course of many decades.

That is why the existing setup deserves a close look before choosing between 32X6.20 and 650-20 or selecting a product within 650-20. Wheel width, tire clearance at the fenders, steering travel, and ride height all matter. A tire that matches the nominal size still needs to suit the car as it sits today, not only how it may have left the factory era.

Inspect the wheels, valve hardware, and overall mounting condition first, then check that the new tires match the car's intended size and 20-inch rim setup. Once mounted, look over sidewall seating, inflation, tread condition, and visible clearances at the fenders and steering components before putting meaningful road miles on the car.

A collector car that sees limited use also deserves a broader mechanical check. Steering play, suspension wear, brake condition, and wheel-bearing health all affect how the car behaves on fresh tires. A short, careful initial drive helps confirm that the tires run true and clear properly, especially on a vehicle from the 1920s where age-related issues can show up quickly.

Tires on a collector 1927 Wills, Sainte Claire 6 Cyl. should be kept clean, properly inflated, and inspected regularly for cracking, cuts, bulges, flat spotting, and slow air loss. Because antique and pre-war cars are often driven infrequently, tire condition matters just as much as tread depth when judging whether the car is ready for use.

Storage plays a major role in longevity. Keeping the car away from prolonged sunlight, moisture, excess heat, and ozone sources helps preserve both the rubber and the sidewall appearance. It is also wise to inspect the tires before every outing and again before a longer drive, since age, long sit times, and older wheel hardware can all affect road readiness.
