The 1929 Packard 626 Series comes from a period when Packard was known for refined engineering, substantial road manners, and the kind of formal presence that still defines a well-restored late-1920s automobile. Tire choice on a car like this is closely tied to authenticity, wheel design, and intended use rather than simple modern replacement shopping. The 1929 Packard 626 Series uses bias-ply tires in 30X5.77 and 30x5 sizing, both tied to 7-inch rim fitment. That makes the decision less about modern alternatives and more about choosing the right vintage-style size format for the car’s actual wheel setup. Careful wheel inspection is especially important before putting a brass-era or pre-war style Packard back on the road.
Which Tire Size Is Right for The 1929 Packard 626 Series
The 1929 Packard 626 Series uses two primary tire sizes, and the difference matters because these are both vintage bias-ply fitments in older sizing systems. The first step is confirming which wheel and tire arrangement is actually on the car, since both sizes are associated with the same 1929 Packard 626 Series 8 Cyl. sub-model and a 7-inch rim diameter is part of the fitment picture for this vehicle.
30X5.77 is an antique size format that expresses the tire by approximate overall diameter and section width, so this tire is about 30 inches tall with a section width near 5.7 inches. It is a bias-ply fitment that suits the vintage wheel and road character expected on a 1929 Packard 626 Series. On a car from this era, this size is usually chosen by owners focused on preserving the proper period-style stance and tire profile. It is worth confirming the actual wheel type and bead-seat design before selecting this size, especially on an older restoration or a car with replacement wheels.
30x5 is also an antique diameter-by-section size, meaning the first number refers to approximate overall diameter while the second refers to section width. This bias-ply fitment is described in beaded-edge style terms, which makes it especially important to match the tire to the wheel design actually fitted to the car. For a 1929 Packard 626 Series, that can affect both restoration presentation and safe mounting practice. Before choosing 30x5, inspect the wheels closely and verify that the car has the correct vintage rim arrangement for this style of tire.
Sub-model fitment is straightforward here because the covered 1929 Packard 626 Series 8 Cyl. uses the same pair of vintage tire sizes. The main issue is not trim-level variation, but confirming which of the two older tire and wheel arrangements is actually on the car before replacement.

1929 Packard 626 Series 8 Cyl.
The 1929 Packard 626 Series 8 Cyl. uses the same two bias-ply tire sizes found across this vehicle page: 30X5.77 and 30x5. That means tire selection depends less on sub-model differences and more on verifying the wheel style, rim details, and restoration setup already present on the car.
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.
Frequently Asked Questions
Owners of a 1929 Packard 626 Series usually need clear guidance on vintage tire sizing, 7-inch rim fitment, wheel-type verification, restoration appearance, and the inspections that matter before returning a pre-war Packard to road use.
Tire Size & Fitment
What tire size fits a 1929 Packard 626 Series?
The 1929 Packard 626 Series uses two primary bias-ply tire sizes: 30X5.77 and 30x5. Both are vintage-format sizes associated with this model, and both appear on the 1929 Packard 626 Series 8 Cyl. rather than being split by multiple trim-specific fitments.
The important step is confirming which wheel and tire arrangement is actually on the car before ordering a replacement. These are not interchangeable modern-style listings, and the difference between an antique flotation-style size and a beaded-edge style size can affect mounting, appearance, and wheel compatibility.
What size rim does a 1929 Packard 626 Series use?
The 1929 Packard 626 Series uses a 7-inch rim diameter with its primary tire fitment. That rim diameter is tied to the 30X5.77 fitment and forms part of the overall wheel and tire setup for this vehicle.
Rim diameter alone is not the whole story on a late-1920s automobile. Older tire systems can also depend on the actual wheel construction and bead-seat design, so the safest approach is to confirm the wheel itself, not just the nominal tire size stamped in old records or noted during a prior restoration.
What does 30X5.77 mean on a 1929 Packard 626 Series?
30X5.77 is an antique diameter-by-section size. The 30 refers to the tire’s approximate overall diameter in inches, while 5.77 refers to its approximate section width, making it a very different sizing language from later alphanumeric, metric, or P-metric tire formats.
That matters because a 1929 Packard 626 Series owner is usually matching more than just height and width. This size needs to be considered alongside wheel type, mounting style, and the visual proportions expected on a pre-war Packard, especially if the car has older replacement wheels or mixed restoration parts.
Choosing the Right Tire
What should I consider when choosing a 30X5.77 tire for a 1929 Packard 626 Series?
Start by confirming that 30X5.77 is the tire size that matches the actual wheel setup on the car. On a 1929 Packard 626 Series, that means looking at the existing wheel design, the 7-inch rim diameter, and whether the car has remained consistent with its earlier restoration or long-term ownership history.
Selection should also reflect how the car will be used. A tour-focused driver may prioritize dependable road manners from a correctly sized bias-ply tire, while a restoration-oriented owner may place more emphasis on preserving the proper vintage profile and overall stance of the Packard.
How do I choose between the available 1929 Packard 626 Series tire sizes?
The choice between 30X5.77 and 30x5 is really a choice between two different vintage tire and wheel arrangements, not simply two modern substitute sizes. Both are bias-ply fitments used on the 1929 Packard 626 Series, but they belong to older sizing conventions that should be matched carefully to the wheel.
A close inspection of the wheels is the best place to begin. On an older Packard, previous restorations, wheel replacements, or long service life can leave a car wearing equipment that differs from what a buyer expects, so visual confirmation matters as much as the old size notation.
What rim-fitment details matter when choosing tires for a 1929 Packard 626 Series?
Rim diameter is the first detail to verify, and the 1929 Packard 626 Series uses a 7-inch rim diameter with its primary setup. Beyond diameter, an owner should also pay close attention to the wheel’s construction because antique tire systems can depend on how the bead area of the wheel is designed.
That is especially important when deciding between 30X5.77 and 30x5. Even when two vintage sizes seem close in overall dimensions, the wheel design they expect may not be the same, so checking the wheel before mounting a new tire is a key part of getting the car road-ready.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Packard 626 Series?
A period-style 1929 Packard 626 Series should stay with one of its proper primary bias-ply sizes, either 30X5.77 or 30x5, depending on the wheel arrangement on the car. The right starting point is preserving the correct vintage tire format and proportions rather than trying to adapt a later-style sizing system.
Appearance on a Packard of this era is closely tied to the wheel and tire relationship. Owners pursuing a highly accurate restoration should compare the current setup against marque references, restoration photos, and other vehicle-specific historical material before deciding which of the two vintage sizes best suits the car.
Does correct tire fitment matter for a 1929 Packard 626 Series restoration?
Correct tire fitment matters a great deal on a 1929 Packard 626 Series because the tire’s diameter, section shape, and wheel relationship strongly influence how the car sits and presents itself. On a pre-war automobile, the tires are a visible part of the restoration rather than a minor finishing detail.
Fitment also affects practicality. A tire that matches the car’s actual wheel design is important not only for appearance, but also for proper mounting and dependable road use, especially on a vehicle that may have seen multiple restorations, wheel changes, or long periods of storage over the decades.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Packard 626 Series?
Yes, modifications can affect tire fitment on a 1929 Packard 626 Series. If the car has replacement wheels, altered suspension components, brake changes, or body work from an older restoration, those changes can influence which of the original-style tire sizes is appropriate and how the tire sits in service.
Even subtle changes matter on a pre-war car with antique tire sizing. A careful owner should verify wheel design, tire-to-fender clearance, steering movement, and overall stance before mounting new tires, particularly if the car’s history includes long-term storage, partial restoration, or parts sourced from another vehicle.
What should I inspect before driving a 1929 Packard 626 Series on new tires?
Before driving a 1929 Packard 626 Series on new tires, inspect the wheels, valve hardware, wheel mounting surfaces, and the condition of the suspension and steering components. It is also wise to check that the tires seat correctly, hold pressure properly, and show no interference through the steering range.
A vintage Packard should also be evaluated as a complete road car, not just as a tire installation. Brake performance, wheel fastener security, alignment condition, and the absence of rubbing under load all deserve attention before any meaningful road use, especially after the car has been inactive.
How should tires on a collector 1929 Packard 626 Series be maintained?
Tires on a collector 1929 Packard 626 Series should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and air loss, and protected from long exposure to sun, heat, moisture, and ozone sources. Low annual mileage does not stop tires from aging, so condition matters as much as tread depth.
Storage habits make a real difference on a pre-war car. A Packard that sits for long periods benefits from a clean, dry environment and periodic checks of both the tires and wheels, with extra attention to any signs that age, old wheel surfaces, or prolonged static loading are affecting serviceability.
