The 1928 Moon 72 Series comes from a fascinating late-1920s period, when independent American automakers still offered distinctive styling and engineering in a fast-changing market. For collectors, that makes the car as much a preservation project as a driver. Tire fitment centers on two bias-ply sizing conventions tied to the same 19-inch wheel: 29X5.50 and 550-19. That means the real choice is less about modernizing the car and more about selecting the right period-style presentation, including blackwall or wide whitewall treatment where available. Before choosing, it helps to confirm which sizing convention best matches the car's existing wheels and restoration direction.
Which Tire Size Is Right for The 1928 Moon 72 Series
The 1928 Moon 72 Series uses two primary tire sizes, and both are bias-ply fitments associated with a 19-inch wheel setup. Because these sizes reflect different vintage sizing conventions rather than a simple modern-size choice, the first step is confirming the exact wheel and the format already used on the car before selecting a tire style and appearance.
A 29X5.50 size uses an older diameter-by-section format, where 29 refers to the tire's approximate overall diameter in inches and 5.50 refers to its nominal section width. On a 1928 Moon 72 Series, that makes it a distinctly early automotive sizing convention suited to period-style bias-ply fitment. Product selection should be approached with attention to how this older format relates to the wheels already on the car and the look the owner wants to preserve. It is a useful size to evaluate when maintaining an authentic late-1920s presentation is part of the goal.
A 550-19 tire uses the classic numeric bias-ply system, with 5.50 indicating nominal section width and 19 identifying the rim diameter in inches. For the 1928 Moon 72 Series, this is a bias-ply fitment that carries the practical advantage of available product choices in BFGoodrich's Silvertown Classic Bias Ply line. Blackwall and 3.25-inch wide whitewall versions are available, giving the car either a more restrained touring look or a brighter restoration-oriented appearance. It is the size to focus on when wheel diameter is confirmed at 19 inches and appearance choice matters.
Sub-model fitment is straightforward here, because the covered 72 Series sub-model uses the same pair of bias-ply tire sizes. Checking the exact sub-model still matters so the car's wheel setup and preferred vintage sizing convention can be matched correctly before ordering tires.

1928 Moon 72 Series 6 Cyl.
The 1928 Moon 72 Series 6 Cyl. uses the same two bias-ply tire sizes associated with this vehicle line, so the main fitment decision is not trim variation but which vintage size convention matches the wheels on the car. That makes tire selection more about proper 19-inch wheel confirmation, sidewall presentation, and restoration direction than about sub-model-specific differences.
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.

Common questions for the 1928 Moon 72 Series usually center on its two vintage tire sizes, 19-inch wheel fitment, period-style bias-ply choices, and what to inspect before putting a collector car back on the road.
Tire Size & Fitment
What tire size fits a 1928 Moon 72 Series?
The 1928 Moon 72 Series uses two primary bias-ply tire sizes: 29X5.50 and 550-19. Both sizes are tied to the vehicle's vintage fitment, and the covered 1928 Moon 72 Series 6 Cyl. uses those same two size references rather than a separate sub-model-specific tire size.
The important next step is confirming which sizing convention matches the wheels already on the car. A 29X5.50 tire uses an antique diameter-by-section format, while 550-19 uses a numeric bias-ply format tied clearly to a 19-inch rim, so the wheel setup should be checked before selecting tires.
What size rim does a 1928 Moon 72 Series use?
The 1928 Moon 72 Series uses a 19-inch rim with its 550-19 bias-ply tire fitment. Available 550-19 products are built for a 19-inch rim and are paired with a rim-width range of 2.50 to 3.00 inches, which is appropriate information when checking wheel compatibility.
Wheel confirmation matters on a car of this age because many collector vehicles have been restored, re-wheeled, or altered over time. Measuring the actual wheel diameter and width on the car helps avoid confusion between older tire-size conventions and makes it easier to choose a tire that matches both the wheel and the intended appearance.
What does 550-19 mean on a 1928 Moon 72 Series?
A 550-19 size is a numeric bias-ply designation. The 5.50 refers to the tire's nominal section width in inches, and the 19 refers to the rim diameter in inches, making it a traditional way of describing a narrow vintage tire built for a 19-inch wheel.
Understanding that format helps separate the tire's width from the wheel size, which is especially useful on late-1920s vehicles where more than one vintage sizing style may appear. Once the 19-inch wheel is confirmed, the choice within 550-19 becomes more about sidewall style, restoration presentation, and matching the car's overall setup.
Choosing the Right Tire
What should I consider when choosing a 550-19 tire for a 1928 Moon 72 Series?
Start with the basics: confirm that the car is using the 550-19 numeric bias-ply fitment and that the wheel is a 19-inch rim within the tire's 2.50 to 3.00 inch rim-width range. From there, the main differences are appearance and product details rather than a change in overall tire category.
For this Moon, available 550-19 choices come from BFGoodrich in the Silvertown Classic Bias Ply series, with blackwall and 3.25-inch wide whitewall versions. That means the decision often comes down to the visual character desired for the car, along with load specification, wheel compatibility, and how closely the tire suits the restoration plan.
What sidewall styles are available for 1928 Moon 72 Series tires?
In 550-19, the 1928 Moon 72 Series has both blackwall and wide whitewall sidewall choices. Those options keep the construction and vintage tire family consistent while changing the car's visual presentation, which can matter a great deal on a late-1920s collector vehicle.
A blackwall usually gives a more restrained, workmanlike appearance, while a wide whitewall adds a brighter restoration-oriented look. The right choice depends on how the car is being finished, what style cues the owner prefers, and whether the goal is understated authenticity or a more formal show-field presentation.
What tire series are available for the 1928 Moon 72 Series?
The available 550-19 products for the 1928 Moon 72 Series are in the BFGoodrich Silvertown Classic Bias Ply series. That keeps the buyer in a traditional bias-ply construction appropriate to the vehicle's era while still allowing a choice in sidewall appearance within the same general tire family.
Since the series itself remains consistent, selection becomes a matter of matching the tire to the car's visual goal and wheel setup rather than choosing between very different product personalities. Checking rim width, confirming the exact size convention used on the car, and deciding between blackwall and wide whitewall are the most useful next steps.
Restoration & Appearance
Which tire should I choose for a period-style 1928 Moon 72 Series?
A period-style 1928 Moon 72 Series should stay with the correct vintage bias-ply sizing and construction, which means focusing on 29X5.50 or 550-19 depending on the wheel setup and the sizing convention already established on the car. Either one keeps the tire choice rooted in the vehicle's late-1920s character.
For many restorations, the decision then shifts to presentation rather than construction type. The available 550-19 products include blackwall and wide whitewall versions, so the owner can tune the look of the car while staying within an appropriate vintage bias-ply format. Exact originality questions should be checked against marque-specific historical references.
Does correct tire fitment matter for a 1928 Moon 72 Series restoration?
Correct tire fitment matters a great deal on a 1928 Moon 72 Series because the tires contribute heavily to the car's stance, visual balance, and restoration credibility. Using the proper vintage size format and bias-ply construction helps the vehicle retain the proportions and character expected of a late-1920s automobile.
It also affects practical fitment. A car restored around one wheel and tire convention may not present correctly if another format is chosen without checking the wheel itself, so measuring the actual rim and reviewing the car's restoration goals should happen before tires are selected. That approach helps appearance and fitment stay aligned.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1928 Moon 72 Series?
Yes, modifications can affect tire fitment on a 1928 Moon 72 Series. If the car has replacement wheels, brake changes, suspension work, or body alterations from an older restoration, those changes can influence which of the two vintage tire-size conventions makes the most sense and whether the wheel dimensions still match the tire.
That is why the actual wheel diameter and width should be measured before new tires are chosen. Clearance around fenders and steering components should also be checked on a modified car, especially if ride height or wheel offset has changed, because an antique vehicle often carries decades of small changes that are easy to overlook.
What should I inspect before driving a 1928 Moon 72 Series on new tires?
Before driving a 1928 Moon 72 Series on new tires, inspect the wheels for cracks, severe corrosion, bent flanges, and proper bead and rim condition. The rest of the chassis should also be checked for obvious steering looseness, worn suspension parts, and anything that could affect how the tires track on the road.
Tire pressure should be set correctly, and the new tires should be rechecked after initial use for air loss or shifting hardware. On a collector car that may sit for long periods, it also makes sense to confirm that the spare, valve stems, and any wheel-mounting hardware are in sound condition before a serious road outing.
How should 550-19 tires on a collector 1928 Moon 72 Series be maintained?
550-19 tires on a collector 1928 Moon 72 Series should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Even when tread wear is minimal, collector-car tires should be watched for sidewall cracking, cuts, bulges, flat spotting, or gradual air loss that may not show up during short moves.
Storage conditions matter almost as much as mileage on an older vehicle. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and moving the car periodically can reduce long stationary loading. A close inspection before each driving season is a smart habit for any lightly used antique automobile.
