The 1927 Davis 94 Series comes from an era when tire fitment was inseparable from the character of the car itself, and owners today usually approach it with equal parts preservation and practicality in mind. On a vehicle of this vintage, the tire decision starts with confirming the exact size and wheel setup already on the car rather than assuming one universal fitment. The 1927 Davis 94 Series is associated with two primary bias-ply sizes, 29X4.95 and 5.00-20, which makes wheel identification especially important. That also means the real choice is not only construction, but which vintage sizing system matches the vehicle. For restoration work or careful road use, matching the tire to the wheel and overall presentation is the key first step.
Which Tire Size Is Right for The 1927 Davis 94 Series
The 1927 Davis 94 Series uses two primary tire sizes, and the first step is identifying which wheel setup is on the car. Both fitments are bias-ply, but they belong to different sizing conventions and use different rim diameters, so confirming the exact sub-model configuration and wheel diameter matters before comparing tire choices.
A 29X4.95 size uses an antique diameter-by-section format, where the first number refers to the tire's approximate overall diameter and the second refers to its section width. For the 1927 Davis 94 Series, this is a bias-ply fitment tied to an early-style wheel setup, so it should be approached as a vintage application rather than a modern metric conversion exercise. Buyers familiar only with later numeric sizes may find this format less intuitive, which makes close wheel verification important. It is the right size to evaluate when the car retains the corresponding antique rim arrangement and a traditional pre-war tire appearance is the goal.
A 5.00-20 tire uses a numeric bias-ply format in which 5.00 represents the nominal section width in inches and 20 identifies the rim diameter. On the 1927 Davis 94 Series, this size reflects a more familiar vintage bias-ply sizing convention than the antique diameter-by-section format, but it still requires careful wheel confirmation before selection. The practical appeal of this size is its straightforward rim identification and its alignment with traditional collector-car tire fitment. It is the size to pursue when the car is equipped with 20-inch wheels and the objective is to stay with a proper vintage-style bias-ply presentation.
Sub-model fitment on the 1927 Davis 94 Series is simple in one sense and important in another: the covered sub-model is associated with both primary tire sizes. That makes wheel and existing-tire verification more important than trim identification alone before choosing a replacement.

Frequently Asked Questions
Questions about 1927 Davis 94 Series tires usually center on identifying the correct vintage size, understanding the difference between 29X4.95 and 5.00-20, and checking wheels carefully before putting a collector car back on the road.
Tire Size & Fitment
What tire size fits a 1927 Davis 94 Series?
The 1927 Davis 94 Series is associated with two primary bias-ply tire sizes: 29X4.95 and 5.00-20. Those are not interchangeable labels for the same tire. They represent different vintage sizing systems, and they correspond to different wheel arrangements on the car.
The practical next step is to inspect the wheels and the tires already on the vehicle before ordering replacements. A collector car from this period may have been changed over time, so the best approach is to confirm the actual rim diameter and the size format currently in use rather than relying only on the model name.
What size rim does a 1927 Davis 94 Series use?
The 1927 Davis 94 Series is associated with two rim diameters because its two tire sizes use different wheels. The 29X4.95 fitment corresponds to a 5.0-inch rim diameter, while the 5.00-20 fitment uses a 20-inch rim.
That difference makes wheel identification the first fitment decision on this vehicle. On an older restored or long-stored car, it is worth checking the wheel itself and the tire sidewall rather than assuming the current setup matches past replacement history. Once the wheel diameter is confirmed, the correct vintage tire size becomes much easier to narrow down.
What does 29X4.95 mean on a 1927 Davis 94 Series?
On a 1927 Davis 94 Series, 29X4.95 is an antique diameter-by-section tire size. In that format, 29 refers to the tire's approximate outside diameter and 4.95 refers to the section width, making it different from later numeric bias-ply sizes such as 5.00-20.
That matters because the size code describes an older style of fitment and should be matched to the correct wheel setup on the car. Buyers more familiar with later alphanumeric or metric tire sizes should treat 29X4.95 as a distinct vintage format, not as a modern dimensional shorthand, and verify the actual wheel before choosing a replacement tire.
Choosing the Right Tire
What should I consider when choosing a tire for a 1927 Davis 94 Series?
Start with the two essentials: the exact tire size on the car and the corresponding wheel diameter. The 1927 Davis 94 Series is associated with 29X4.95 and 5.00-20, both in bias-ply construction, so selecting the right tire begins with matching the vehicle's actual vintage wheel setup.
After size confirmation, think about how the car will be used and how original a presentation you want to preserve. A lightly driven restoration may prioritize a traditional bias-ply look, while a regularly exercised collector car still needs close attention to wheel condition, tire age, and physical clearance before any replacement tire is put into service.
How do I choose between 29X4.95 and 5.00-20 tires for a 1927 Davis 94 Series?
The choice between 29X4.95 and 5.00-20 is determined by the wheel and fitment setup on the car, not by personal preference alone. Both are primary bias-ply sizes associated with the 1927 Davis 94 Series, but they use different rim diameters and belong to different vintage sizing conventions.
A practical inspection usually settles the question quickly. Check the size molded into the current tire if it is readable, then confirm the wheel diameter directly. Because cars from this era may have seen replacement wheels or older restoration work, physical verification is more dependable than assumption when deciding which tire size belongs on your particular Davis.
Why is wheel confirmation so important when choosing 1927 Davis 94 Series tires?
Wheel confirmation matters because the 1927 Davis 94 Series is tied to two different bias-ply tire sizes with two different rim diameters. A 29X4.95 tire and a 5.00-20 tire are not simply alternate labels, so selecting by appearance alone can send a buyer in the wrong direction.
On a nearly century-old vehicle, wheels may not be original to the car, and previous owners may have replaced tires using what was available at the time. Measuring the wheel and reading any surviving sidewall markings helps establish a solid starting point. That extra step protects both the restoration process and the car's roadworthiness.
Restoration & Appearance
Which tire should I choose for a period-style 1927 Davis 94 Series?
For a period-style 1927 Davis 94 Series, the right starting point is the tire size and wheel setup that actually belongs on the car: either 29X4.95 or 5.00-20 in bias-ply construction. Both sizes suit the vehicle's era, but each must match the wheel arrangement already in place.
Appearance on a late-1920s vehicle is shaped as much by proportion and stance as by sidewall treatment. A buyer focused on restoration should first preserve correct overall fitment, then compare vintage-style tire presentations within that size. When exact originality matters, marque-specific references and restoration records are worth consulting before making a final choice.
Does correct tire fitment matter for a 1927 Davis 94 Series restoration?
Correct tire fitment matters a great deal on a 1927 Davis 94 Series because the tire is a visible and structural part of the car's stance, wheel relationship, and period character. Using the right size format, whether 29X4.95 or 5.00-20, helps preserve the way the vehicle presents overall.
Restoration-minded owners should look beyond whether a tire simply mounts on the wheel. The sizing system, rim diameter, and overall vintage look all influence how authentic the finished car appears. On an early vehicle like this, taking time to confirm fitment before installation usually pays off in both appearance and drivability.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1927 Davis 94 Series?
Yes, modifications can affect tire fitment on a 1927 Davis 94 Series. If the car has replacement wheels, brake changes, altered suspension parts, or body and fender work from an older restoration, those changes can influence which tire size the car can use safely and how much clearance remains.
That is why physical inspection matters more than assumption on a vehicle of this age. Check wheel diameter, wheel condition, and the space around the tire at full steering movement before choosing replacements. Even when the car is associated with a correct vintage size, changed hardware can alter the practical fitment picture.
What should I inspect before driving a 1927 Davis 94 Series on new tires?
Before driving a 1927 Davis 94 Series on new tires, inspect the wheels, valve hardware, and overall mounting condition, then confirm that the tires clear fenders and steering components through their full range of movement. Tire pressure, bead seating, and wheel integrity deserve close attention on a collector vehicle of this era.
A short, careful shakedown drive is wise before planning any extended trip. Keep an eye out for vibration, pulling, rubbing, or signs of uneven seating after the first miles. On an older car that may sit for long periods, regular rechecks help catch air loss or fitment issues before they become more serious.
How should tires on a collector 1927 Davis 94 Series be maintained?
Tires on a collector 1927 Davis 94 Series should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when tread wear is minimal, age-related cracking, flat spotting, cuts, bulges, and slow air loss can become more important than mileage on a low-use antique vehicle.
Storage conditions also play a major role in tire life. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps protect the sidewalls, and periodic movement can reduce stress from sitting in one position too long. A close inspection before each driving season is a sensible routine for a pre-war collector car.
