Packard Model Thirty Tires

Packard Model Thirty uses five tire sizes across the 1907-1910 production span: 34X4 for 1907-1908 on 26-inch rims, 34X4.5 for 1907 on 25-inch rims, 36X3.5 for 1908 on 29-inch rims, 36X4 for 1908-1910 on 28-inch rims, and 36X4.5 for 1908-1910 on 27-inch rims. All of these are antique diameter-by-section sizes rather than modern metric or alphanumeric sizes.

The practical takeaway is that year alone does not always settle the question, especially for 1908. Start with the model year, then confirm the actual wheel diameter on the car and compare it to the correct size group before choosing a tire.

On a Packard Model Thirty, 36X4 is an antique size code. The 36 refers to the tire's approximate overall outside diameter in inches, not the wheel diameter, while the 4 refers to a nominal 4-inch section width. The products available in 36X4 fit 28-inch rims.

That distinction is essential because early size markings can mislead modern buyers into thinking the first number is the wheel size. If your Packard Model Thirty has 28-inch wheels and falls within the years that used 36X4, that is the point where this size should stay under consideration.

The 1908 Packard Model Thirty is the most complex year in this range because it appears with 34X4, 36X3.5, 36X4, and 36X4.5. Those sizes do not represent minor variations of a single wheel; they correspond to different rim diameters, including 26-inch, 29-inch, 28-inch, and 27-inch applications.

That means a 1908 Packard Model Thirty owner needs more than the year to select tires correctly. Check the wheel diameter on the car and compare the existing tire marking if present, then use that combination to narrow the correct size rather than guessing from the production year alone.

Packard Model Thirty uses several rim diameters across the sizes listed here. The available pairings are 34X4 with 26-inch rims, 34X4.5 with 25-inch rims, 36X3.5 with 29-inch rims, 36X4 with 28-inch rims, and 36X4.5 with 27-inch rims. On these antique sizes, the rim diameter is not contained in the first number of the size code.

A buyer working with an unrestored or modified car should treat rim diameter as the first check, not the last. Measure the wheel or verify it from reliable vehicle records before selecting a tire, because an early Packard can easily wear a size that looks close in name but fits an entirely different rim.

A 1908 Packard Model Thirty can use 34X4, 36X3.5, 36X4, or 36X4.5, so the correct size must be matched to the car's actual wheel diameter. Those sizes correspond to 26-inch, 29-inch, 28-inch, and 27-inch rims respectively, which makes the wheel itself the deciding factor when the year alone leaves multiple choices open.

The best approach is to compare the tire marking on the car, inspect the wheel diameter, and then verify that the replacement tire matches both. If the car is part of a restoration, original records, period photos, and marque expertise can help settle which of the listed combinations belongs on that specific Packard Model Thirty.

Packard Model Thirty tires in this range are available with blackwall, all white, all gray, and wide whitewall sidewall styles. The selection varies by size, with some sizes offering multiple visual treatments and others staying narrower in choice depending on the series and brand offered for that particular fitment.

Sidewall appearance matters on a brass-era car because it strongly affects the finished look of a restoration or touring car. A buyer choosing for authenticity should compare the sidewall style to the intended presentation of the car, whether that is formal restoration, touring use, or a period-inspired look.

The brands represented for Packard Model Thirty tire sizes here are Michelin, BFGoodrich, Firestone, Universal Vintage Tire, and Diamond. Those brands appear across several brass-era series, including high-pressure, cord, smooth-tread, classic bias-ply, and racing-oriented offerings depending on the size.

Brand choice on an early Packard often comes down to the balance between period appearance, tread style, and the exact size needed for the car. Once the correct size and rim diameter are confirmed, comparing brands can help narrow the tire that best suits the car's restoration goals and intended driving use.

One Packard Model Thirty tire in the 36X4 size is listed as new-old-stock original period production: a BFGoodrich Silvertown Cord wide whitewall. New-old-stock means an older tire that was produced in the period and preserved rather than a newly manufactured reproduction, so its age is part of the product's significance.

Collectors often value NOS tires for display, historical interest, or highly authentic presentation, but age matters more than appearance when road use is considered. A Packard Model Thirty owner should view an NOS tire as something that deserves specialist evaluation before any driving decision is made.

Packard Model Thirty should be stored in a cool, dry, dark environment with the tires kept away from direct sunlight, electric motors, ozone sources, and petroleum contamination. Because these are brass-era bias-ply tires with tall, narrow profiles, long static loading can also stress the casing and distort the shape over time.

Many collector owners reduce that stress by moving the car periodically or supporting it so weight is not left on one contact patch for months at a time. Keeping inflation appropriate for storage and inspecting sidewalls before the next outing helps preserve the tire and the car's driving quality.

Tires on a Packard Model Thirty should be inspected before each drive and more thoroughly at regular intervals even when the car sees only occasional use. Brass-era tires deserve close attention to sidewall cracking, tread separation, bead condition, tube-related issues, and any sign that age rather than mileage is becoming the main concern.

A practical inspection routine includes checking inflation, looking for uneven wear, and examining the tire after the car has been stationary for extended periods. On an early Packard, small issues are worth addressing early because low-use collector tires often age out long before they wear out.

Packard Model Thirty tires should be replaced when age, cracking, casing deterioration, impact damage, or persistent air-loss issues show that the tire is no longer sound, even if tread depth still appears usable. Collector tires often reach that point through time and storage conditions rather than mileage, and that is especially true on brass-era constructions.

A tire that still looks presentable can still be a poor road candidate, which is why age-sensitive inspection matters on cars of this period. That standard is even more important with any NOS Packard Model Thirty tire, since originality does not override the effects of age on rubber and fabric construction.

Packard Model Thirty appears here with several period-appropriate size and series combinations rather than a single universal original tire. The available products include series such as Firestone High Pressure, BFGoodrich Silvertown Cord, Universal Classic Bias Ply, Diamond Smooth Tread, Michelin Milltown, and a Vintage Race offering in one size, reflecting the range of early tire constructions and appearances associated with the period.

For a strict restoration, the key is matching the specific year, wheel diameter, and visual presentation of the individual car. Original owner literature, period photographs, and marque references remain the best way to determine which period style is the most faithful choice for a particular Packard Model Thirty.

Correct tire fitment can matter significantly to the presentation and judged authenticity of a Packard Model Thirty. Size, sidewall style, tread style, and overall stance all influence whether the car looks properly sorted for its era, and an obviously incorrect wheel-and-tire combination can distract from otherwise careful restoration work.

For owners concerned with concours standards or long-term collector value, tire choice should be treated as part of the restoration rather than an afterthought. Matching the year, wheel diameter, and period look of the car as closely as possible is usually the most defensible path, especially when club or event judging is involved.

Packard Model Thirty tires are offered here in blackwall, all white, all gray, and wide whitewall versions depending on size and series. Because this is a brass-era automobile, sidewall choice is part of the period character of the finished car, and more than one historically appropriate visual treatment may be available within the correct size.

The right answer depends on how the specific Packard Model Thirty is being restored and presented. A buyer aiming for authenticity should compare the available sidewall style to the car's intended period look and verify that the chosen appearance aligns with the exact year and configuration being restored.

A Packard Model Thirty can be driven only within the limits of an early brass-era automobile, and tire condition is only one part of that equation. These tall bias-ply tires are appropriate to the period, but safe use depends on the age and condition of the tires, proper tube installation, wheel condition, and the readiness of the car's steering, brakes, and chassis.

Public-road use should be conservative and approached as vintage motoring rather than modern driving. If the car has newly fitted reproduction tires and has been mechanically reviewed, careful touring can be realistic; if it has aged or NOS rubber, the wiser role may be display, parade, or very limited operation.

Before driving a Packard Model Thirty, check tire inflation, sidewall condition, tread condition, bead seating, and the general integrity of the wheel and rim. On an early Packard, it also makes sense to verify that the tire size actually matches the wheel diameter, since these antique size codes do not state the rim diameter in the same way modern tires do.

A short pre-drive inspection can prevent the most common collector-car tire problems from turning into roadside issues. Owners should also confirm that the car's brakes, steering linkage, and wheel fastenings are in sound condition, because road safety on a Packard Model Thirty depends on the entire vehicle system, not the tires alone.

A Packard Model Thirty should be driven at restrained, period-appropriate speeds even when fitted with correct reproduction tires. Brass-era tire construction, narrow tread width, early chassis design, and the general mechanical character of the car all favor slow to moderate touring rather than sustained high-speed operation.

The right pace is the one that respects the age of the automobile and leaves a wide margin for steering, braking, and road surface changes. If the Packard Model Thirty is fitted with older or NOS tires, speed expectations should become even more conservative and road use should be limited accordingly.
