1927 Falcon Tire Fitment Guide

1927 Falcon vehicles use two tire sizes: 29X4.95 and 5.00-20. Both sizes apply to the 1927 Falcon 6 Cyl., but they do not mount on the same wheel diameter. The 29X4.95 size fits a 23-inch rim, while the 5.00-20 size fits a 20-inch rim, and both are bias-ply constructions in keeping with the period.

That means a 1927 Falcon owner should verify the actual wheels on the car before choosing a tire. A car that has been restored, repaired over time, or converted to a different wheel setup may no longer match what another Falcon owner is using. Start by reading the existing tire size if present, then confirm the wheel diameter directly before moving on to product selection.

On a 1927 Falcon, 29X4.95 is an antique diameter-by-section size. The first number, 29, refers to the overall tire diameter in inches, while 4.95 refers to the nominal section width in inches. That is different from later sizing systems that use the wheel diameter after the dash.

This older style of sizing is common on pre-war automobiles that still sit close to the antique end of the tire-evolution timeline. A 1927 Falcon running 29X4.95 should be matched to the correct 23-inch wheel, and owners focused on preserving an early period appearance usually want to stay with the same vintage-style casing format rather than mixing in a later size system.

On a 1927 Falcon, 5.00-20 is a numeric bias-ply size. The 5.00 refers to the nominal section width in inches, and the 20 identifies the wheel diameter in inches. Unlike 29X4.95, this code does not begin with the overall tire diameter.

That difference matters because a 5.00-20 tire belongs on a 20-inch wheel, not on the 23-inch wheel used by the 29X4.95 size. A 1927 Falcon owner comparing the two should think of them as two separate fitment paths tied to wheel diameter first. Once the wheel size is confirmed, the rest of the decision becomes much more straightforward.

A 1927 Falcon owner should not choose between 29X4.95 and 5.00-20 by preference alone, because the two sizes fit different wheel diameters. The 29X4.95 size belongs on a 23-inch rim, while the 5.00-20 size belongs on a 20-inch rim. Both are bias-ply tires, so the question is primarily one of correct wheel fitment and period-appropriate sizing rather than bias-versus-radial behavior.

If your 1927 Falcon still has its established wheel setup, staying with that size is usually the most straightforward route for appearance and fit. If the car has been apart for years or acquired with loose wheels and tires, measure and verify before making a selection. On a late-1920s car, assuming one size from another Falcon can lead to an expensive mismatch.

1927 Falcon vehicles are served through period-style tire offerings in the sizes used by the Falcon 6 Cyl., with product selection organized around the two applicable sizes rather than a broad modern brand spread. For a car of this era, the important distinction is usually whether the tire matches the correct vintage sizing system and wheel diameter instead of chasing a large number of interchangeable brand options.

That makes brand choice secondary to correct fitment and visual authenticity on a 1927 Falcon. Once you know whether your car needs 29X4.95 or 5.00-20, you can compare the products available in that size and decide which presentation best suits your restoration or touring plans. On pre-war cars, getting the right silhouette and size relationship is often the bigger victory.

1927 Falcon tires are typically chosen for their period-correct pre-war appearance, which means sidewall presentation matters as much as the raw size code for many restorations. The available styles are tied to the individual tire options in 29X4.95 and 5.00-20, and owners usually select them to complement the late-1920s look of the car rather than to create a modernized appearance.

For a 1927 Falcon that will be judged, photographed, or restored with historical sensitivity, sidewall style should match the car's era and overall presentation. For a driver, the same visual choice still affects the character of the finished car even if strict originality is not the goal. It is worth deciding whether you want a more formal restoration look or a simpler utilitarian look before narrowing your tire selection.

A 1927 Falcon must first be matched by wheel diameter, since its two tire sizes do not share the same rim size. The 29X4.95 fits a 23-inch wheel and the 5.00-20 fits a 20-inch wheel. Rim width should then be confirmed against the exact tire being considered and the wheel actually on the car.

That extra step matters on a car from 1927 because wheels may have been swapped during decades of maintenance and restoration. Even when the tire size is correct, an unsuitable rim width can affect casing shape and how the tire sits on the wheel. Confirming both diameter and width before installation is the safest path for fit and appearance.

A 1927 Falcon should be approached as a tube-era vehicle, especially given the bias-ply pre-war tire sizes involved and the style of wheels commonly associated with the period. Inner-tube requirements should be confirmed against the exact tire chosen and the wheel construction on the car, since the wheel itself is part of the decision, not just the tire size.

Tube selection also needs to match the tire size and valve arrangement being used. On an older wheel, the condition of the rim surface, valve hole, and flap area can matter just as much as the new tire. When fitting tires to a 1927 Falcon, treat tube, flap, rim condition, and tire as one complete system rather than separate parts.

A 1927 Falcon should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age tire rubber. Because both Falcon sizes are bias-ply designs, they are more prone to temporary flat-spotting during long static storage than a modern radial would be.

Moving the car periodically, keeping the tires properly inflated, and avoiding long-term parking on damp concrete all help preserve the casing shape. If a 1927 Falcon will sit for a season or longer, many collectors either roll the car occasionally or support it in a way that reduces constant load on one patch of the tire. That approach protects both the tires and the suspension.

On a 1927 Falcon, tire life is usually judged more by age, storage conditions, and inspection results than by mileage alone. Collector-car tires often age out before they wear out, so many owners begin evaluating them carefully around five to seven years and treat about ten years as a point where replacement deserves serious consideration regardless of tread depth.

A Falcon that sees only occasional fair-weather driving can still have tires that harden, crack, or lose resilience over time. Check the manufacturing date code where applicable and pay attention to sidewall condition, ride feel, and air retention. Even on a lightly used pre-war car, old-looking tread is not a reliable sign that the tires are still ready for service.

Tires on a 1927 Falcon should be inspected before every drive, and they deserve an especially thorough check before a tour, parade, or any outing that keeps the car on the road for an extended period. Look for sidewall cracking, cuts, bulges, uneven wear, and any sign that the tire is not holding pressure as expected.

On a car of this age, inspection should also include valve stems and, where applicable, the tube-related hardware and rim condition. A few extra minutes in the garage can catch the kind of issue that turns a pleasant drive into a roadside problem. Pre-war cars reward routine attention, and tire inspection is one of the easiest habits to build.

A 1927 Falcon 6 Cyl. would have been fitted with bias-ply tires, because radial construction was not part of ordinary American passenger-car practice in that era. The relevant sizes associated with the Falcon 6 Cyl. are 29X4.95 and 5.00-20, reflecting the transitional sizing conventions seen in the late 1920s. Original-equipment brand choice could vary by market, dealer practice, and period supply.

For a restoration, that means construction type and size are the first authenticity checkpoints. If you are chasing exact delivery-day correctness for a specific car, a Falcon marque specialist, period sales literature, or regional club archive is the best next source for confirmation. Most owners can get very close by staying with the proper bias-ply format and the correct wheel-diameter pairing.

Correct tire fitment matters on a 1927 Falcon because judges and knowledgeable enthusiasts often notice whether the size, construction, and overall sidewall presentation suit the period. A mismatch between a 23-inch antique-format fitment and a 20-inch numeric fitment would be visually obvious, and any size that sits wrong for the wheel can change the car's stance in a way that looks out of period.

Owners preparing a show car should think beyond simple roadworthiness and consider how the tire contributes to authenticity. Even when an event is less formal, proper pre-war sizing helps the car look settled and believable. If the goal is top-tier judging, consult the standards used by the club or event that applies to your 1927 Falcon rather than relying on broad assumptions.

1927 Falcon sits in an era when the industry was moving away from older diameter-by-section tire descriptions toward more standardized numeric sizing tied directly to wheel diameter. That is why you see both 29X4.95 and 5.00-20 associated with the Falcon 6 Cyl. They reflect different ways of expressing tire dimensions during a period of rapid standardization in the American market.

For a restorer, that historical overlap is useful because it explains why two seemingly unrelated size codes can both belong to the same year and make. It also reinforces why wheel verification matters so much on late-1920s cars. Treat the two codes as historically appropriate but not interchangeable, and your 1927 Falcon project will stay on firmer ground.

A properly fitted, correctly inflated, and sound-condition tire can make a 1927 Falcon suitable for normal collector-car road use, but expectations should remain in line with the car's age and bias-ply construction. On a late-1920s automobile, the broader limits often come from braking, steering precision, road manners, and overall vehicle condition rather than from treating it like a modern interstate cruiser.

That means a 1927 Falcon should be driven with moderate speeds, longer following distances, and regular condition checks before any substantial trip. A fresh set of correct tires improves confidence, but it does not change the fundamental behavior of a pre-war car. Owners who respect the vehicle's era and use it accordingly usually have the best experience.

Inflation pressure for a 1927 Falcon should follow the recommendation for the exact tire being used and the factory guidance for the vehicle where that information is available. Because 29X4.95 and 5.00-20 are different sizes on different wheel diameters, pressure should never be assumed to transfer from one Falcon setup to the other just because both belong to the same year and make.

Using too much or too little air can affect ride height, steering feel, tread contact, and casing stress on a lightweight pre-war car. Start with the tire maker's published guidance for the chosen size and compare that against period vehicle recommendations when available. Once the car is on the road, monitor wear and pressure retention rather than setting it once and forgetting it.

Before a longer drive in a 1927 Falcon, inspect each tire for weather checking, cuts, bulges, embedded debris, abnormal wear, and proper inflation. Check the valve stems and spare as well, and if the car uses tube-type hardware, make sure the full assembly is in good order. Tire readiness is only one part of the preparation, but it is one of the most visible and important.

A pre-war car also deserves a broader once-over that includes brakes, steering, wheel bearings, and basic fluid checks before heading out for distance. The goal is not to overcomplicate every outing, but to match your preparation to the age of the machine. When a 1927 Falcon is checked carefully, it is much easier to enjoy the trip with confidence.
