The 1909 Packard Model Thirty came from the Brass Era, when Packard was building large, prestigious automobiles for owners who expected refinement, road presence, and durability on early American roads. Tire choice on a car of this age is closely tied to authentic proportions and the correct beaded-edge presentation. The 1909 Packard Model Thirty uses two primary bias-ply sizes, 36X4 and 36X4.5, both in antique diameter-by-section form. Available choices include blackwall, all white, and wide whitewall styles across period-style series from Firestone, BFGoodrich, Diamond, and Universal Vintage Tire. The key is confirming which wheel setup the car carries and choosing a tire that suits restoration priorities as well as intended road use.
Which Tire Size Is Right for The 1909 Packard Model Thirty
The 1909 Packard Model Thirty uses two primary tire sizes, and the first step is identifying which wheel setup is on the car. Both sizes are bias-ply antique beaded-edge tires, but they pair with different rim diameters, so confirming the wheel itself matters before comparing sidewall style, brand, or period-style tread presentation.
A 36X4 tire uses an early size system in which the first number refers to the tire's approximate outside diameter and the second number refers to its section width. On the 1909 Packard Model Thirty, this is a bias-ply beaded-edge fitment suited to Brass Era wheel and tire construction. Within this size, choices include blackwall, all white, and wide whitewall presentations from Firestone, BFGoodrich, Diamond, and Universal Vintage Tire across period-style series such as Firestone High Pressure, Silvertown Cord, and Diamond Smooth Tread. It is the right size to evaluate only after confirming the car carries the wheel setup intended for 36X4 tires.
A 36X4.5 tire follows the same antique sizing convention, with an approximate 36-inch overall diameter and a wider 4.5-inch section width than 36X4. For the 1909 Packard Model Thirty, it remains a bias-ply beaded-edge tire and belongs to early motoring applications where wheel compatibility is critical. Available options include blackwall and all white styles from Firestone, BFGoodrich, and Universal Vintage Tire, including Firestone High Pressure and Silvertown Cord series. This size is worth considering when the car is set up for the wider tire and the corresponding wheel diameter used with 36X4.5.
Fitment is straightforward here because the covered Standard sub-model can use either of the two primary tire sizes. Even so, checking the exact wheel setup remains essential because 36X4 and 36X4.5 do not share the same rim diameter.

1909 Packard Model Thirty Standard
The 1909 Packard Model Thirty Standard uses either 36X4 or 36X4.5, both as antique bias-ply beaded-edge fitments. That means tire selection starts with confirming which wheel and rim arrangement is on the car, then narrowing the choice by sidewall appearance and period-style series.
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.

Tire Size & Fitment
What tire size fits a 1909 Packard Model Thirty?
The 1909 Packard Model Thirty uses two primary tire sizes: 36X4 and 36X4.5. Both are antique beaded-edge bias-ply sizes, and the Standard sub-model can use either one depending on the wheel setup installed on the car.
The important difference is not just width. These two sizes are built around different rim diameters, so the correct choice starts with the actual wheels on the vehicle rather than appearance alone. On an early Packard, many cars have been restored, repaired, or re-equipped over the years, making a physical wheel check essential before selecting tires.
What size rim does a 1909 Packard Model Thirty use?
Rim diameter depends on which tire size the 1909 Packard Model Thirty is carrying. A 36X4 tire uses a 28-inch rim, while a 36X4.5 tire uses a 27-inch rim, even though both tires have an approximate 36-inch outside diameter.
That early sizing format can be confusing because the first number is not the wheel diameter. On Brass Era fitments, the wheel and the tire size must match exactly, especially with beaded-edge construction. Measuring the wheel before ordering helps avoid choosing the right-looking tire in the wrong configuration for the car.
What does 36X4 mean on a 1909 Packard Model Thirty?
On a 1909 Packard Model Thirty, 36X4 is an antique diameter-by-section tire size. The 36 refers to the tire's approximate overall diameter, while the 4 refers to its section width in inches rather than the wheel diameter.
That matters because modern buyers often expect the final number to identify rim size, but this older system does not work that way. A 36X4 tire belongs on a 28-inch rim in this application. Reading the size correctly helps separate the tire's physical proportions from the wheel it is intended to fit.
Choosing the Right Tire
What should I consider when choosing a 36X4 or 36X4.5 tire for a 1909 Packard Model Thirty?
Start with the correct tire size for the wheel setup on the car, since the 1909 Packard Model Thirty can use either 36X4 or 36X4.5. After that, compare construction style, sidewall appearance, tire series, and any stated load specifications that suit the vehicle's intended use.
A restoration-focused car may call for a more traditional visual presentation, while a touring car may place more emphasis on matching the wheel and tire combination already in service. It also helps to compare details such as blackwall versus white sidewalls and the specific period-style series offered in the size you need.
What sidewall styles are available for 1909 Packard Model Thirty tires?
Sidewall choices for the 1909 Packard Model Thirty include blackwall, all white, and wide whitewall, depending on the tire size and product selected. Those options appear across the available 36X4 and 36X4.5 bias-ply beaded-edge tires.
Sidewall treatment has a strong effect on how a Brass Era Packard presents, especially on a large early touring or formal car. The right choice depends on the look you want and the historical direction of the restoration. It is worth comparing the sidewall style only after confirming the correct size and wheel setup first.
What brands offer tires for the 1909 Packard Model Thirty?
The 1909 Packard Model Thirty has tire options from Firestone, BFGoodrich, Diamond, and Universal Vintage Tire. Availability varies by size, with 36X4 and 36X4.5 each offering a slightly different mix of brands, sidewall styles, and tire series.
Brand choice on a vehicle this old is often tied to appearance as much as fitment, since the tire's tread style and sidewall presentation help shape the finished look. Rather than treating one brand as automatically preferable, compare which company offers the exact size, visual style, and construction details that match your Packard's setup.
Restoration & Appearance
Which tire should I choose for a period-style 1909 Packard Model Thirty?
A period-style choice for a 1909 Packard Model Thirty starts with the correct beaded-edge bias-ply size for the wheels on the car, either 36X4 or 36X4.5. From there, the visual direction can be shaped through traditional series such as Firestone High Pressure, Silvertown Cord, or other vintage-style offerings.
Because Brass Era restorations vary in historical target, the best visual match depends on how the car is being presented rather than on one universal answer. Sidewall treatment also changes the result significantly. When exact originality matters, it helps to compare the tire choice against period photos, marque references, and restoration records for the specific car.
Does correct tire fitment matter for a 1909 Packard Model Thirty restoration?
Correct tire fitment matters a great deal on a 1909 Packard Model Thirty because tire size affects both appearance and wheel compatibility. With early beaded-edge tires, selecting between 36X4 and 36X4.5 is not simply a styling decision, since each size corresponds to a different rim diameter.
A Brass Era Packard can lose the right visual proportions quickly if the tire width or wheel pairing is off. Proper fitment also helps preserve the intended stance of the car and keeps the restoration mechanically coherent. Before focusing on tread style or sidewall color, verify which wheel and tire combination belongs on the specific restored vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1909 Packard Model Thirty?
Yes, modifications can affect tire fitment on a 1909 Packard Model Thirty, especially on a vehicle that may have had wheel changes, brake work, hub alterations, or long-ago restoration updates. Because this Packard uses antique beaded-edge tire sizes, even a seemingly minor wheel change can alter which tire size is appropriate.
Many early cars have been through decades of repairs, parts substitutions, and non-original wheel setups. That makes a physical inspection more important than assumptions based on model name alone. Check the wheel dimensions already on the car and inspect for clearance at the fenders, suspension, and steering range before selecting replacement tires.
What should I inspect before driving a 1909 Packard Model Thirty on new tires?
Before driving a 1909 Packard Model Thirty on new tires, inspect the wheels, valve hardware, and overall mounting condition, then confirm that tire pressure matches the tire's requirements. It is also wise to check steering movement, wheel security, and whether the tires seat properly on the rims.
A broader road-use check should include sidewall condition, signs of cuts or shipping damage, and basic clearance through full steering travel. On a Brass Era car, worn wheel components or loose hardware can matter as much as the tires themselves. A cautious short drive and reinspection afterward helps catch issues before longer use.
How should 36X4 or 36X4.5 tires on a collector 1909 Packard Model Thirty be maintained?
Collector-car tires on a 1909 Packard Model Thirty should be maintained with regular pressure checks, visual inspections for cracking or cuts, and periodic review of tread and sidewall condition. Since these are specialty bias-ply tires for an early automobile, long stationary storage and environmental exposure deserve close attention.
Good storage habits help preserve both appearance and service life. Keep the Packard away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment when possible, and inspect the tires before every outing rather than relying on mileage alone. Low-use collector vehicles often age their tires more by time and storage conditions than by road wear.
