1933 Packard Tire Fitment Guide

1933 Packard vehicles use two tire sizes, and they are model-specific rather than shared across the whole make. The 1933 Packard 12 Cyl. uses 750-17, while the 1933 Packard 8 Cyl. uses 700-17. Both sizes mount on 17-inch rims. Rim width guidance varies by the specific tire selected, with examples including 4-inch fitments, 3.5 to 4.0-inch fitments, and 5.50 to 6.00-inch fitments depending on the exact product.

That means year and make alone are not enough for a confident choice on a 1933 Packard. The first step is identifying whether the car is an 8-cylinder or 12-cylinder model, then comparing the selected tire's stated rim-width range to the wheel on the car. Once the size is confirmed, the remaining decision is usually brand and sidewall style, especially on a restoration where blackwall, double whitewall, or wide whitewall can change the car's overall presentation.

On a 1933 Packard, 700-17 is a numeric bias-ply tire size. The 700 portion refers to a nominal section width using the older numeric sizing convention, and the 17 identifies the wheel diameter in inches. For 1933 Packard applications, that size belongs to the 8 Cyl. models. It is an era-correct prewar American fitment style, and current offerings in that size are bias-ply tires rather than modern metric radials.

Understanding that code helps separate wheel diameter from overall tire character. A 700-17 tire is not interchangeable with every 17-inch tire simply because the rim diameter matches; the width and intended Packard application still matter. If your car is an 8-cylinder model, 700-17 is the proper starting point, and then you can compare blackwall or whitewall appearance, brand preference, and the tire's approved rim-width range before making the final selection.

On a 1933 Packard, 750-17 is also a numeric bias-ply size. The 750 indicates a larger nominal section width than 700-17, and the 17 again refers to a 17-inch wheel. In the 1933 Packard lineup, this size is used on the 12 Cyl. models. That makes it a model-specific prewar luxury-car fitment rather than a universal size used across all 1933 Packards.

The practical value of decoding 750-17 is avoiding confusion between shared wheel diameter and correct overall size. A 12-cylinder Packard owner should start with 750-17, then compare the available sidewall treatments and the specific tire's rim-width recommendation. That keeps the search aligned with the car's intended fitment and avoids accidentally stepping down to the smaller eight-cylinder size simply because both versions of 1933 Packard use 17-inch wheels.

1933 Packard tires are available in Blackwall, Double-Whitewall, and Wide Whitewall styles, depending on size and brand. The 750-17 choices for the 12 Cyl. include Firestone and BFGoodrich options across those sidewall treatments, and the 700-17 choices for the 8 Cyl. include Firestone and Ensign options in the same general range. All of them are bias-ply tires, so the visual choice is about period appearance rather than changing to a different construction type.

For a 1933 Packard, sidewall style has a major effect on how formal or understated the car looks. Blackwalls generally suit a more restrained presentation, while double whitewalls and wide whitewalls create a more prominent Classic Era luxury look. The right choice often depends on the car's restoration theme, body style, and how authentic you want the finished appearance to feel, so it is worth matching the sidewall to the personality of the specific Packard.

Three brands appear in current 1933 Packard fitments: Firestone, BFGoodrich, and Ensign. The 750-17 size used on 1933 Packard 12 Cyl. models is available from Firestone and BFGoodrich, while the 700-17 size used on 1933 Packard 8 Cyl. models is available from Firestone and Ensign. All listed choices are bias-ply tires built in period-style sizing, which keeps the overall fitment appropriate to the car's era.

Brand choice on a 1933 Packard usually comes down to the size your model requires, then the sidewall look and tire series you prefer. Some owners want a familiar American heritage name on a senior classic, while others simply want the sidewall treatment and visual proportions that best suit the car. Once the correct size is established, comparing the brand offerings within that size helps narrow the field without crossing into the wrong fitment for the model.

For the 1933 Packard 12 Cyl., both Firestone Balloon and BFGoodrich Silvertown Classic Bias Ply are offered in 750-17, but they differ in sidewall treatments and some listed specifications. Firestone Balloon appears in Blackwall and Double-Whitewall form with a listed 4-inch rim width and a maximum load figure of 1870 pounds at 40 psi where stated. BFGoodrich Silvertown Classic Bias Ply appears in Blackwall and Wide Whitewall form, with one listed version showing 1646 pounds at 36 psi and a 5.50 to 6.00-inch rim-width range.

That comparison matters when a 1933 Packard owner is matching the tire to both the wheel and the visual style of the restoration. If the car's wheel falls within the stated range of one product but not another, that narrows the field quickly. The sidewall appearance is the other major separator, since a Blackwall, Double-Whitewall, and Wide Whitewall each create a different period impression on a senior Packard even when the nominal tire size remains the same.

Rim width depends on the exact tire selected for a 1933 Packard. In 700-17, listed fitments include 4-inch rims on several Firestone Balloon tires and 3.5 to 4.0-inch rims on an Ensign B5 Blackwall tire. In 750-17, one Firestone Balloon listing shows a 4-inch rim width, while one BFGoodrich wide whitewall listing shows a 5.50 to 6.00-inch range. All of these tires use 17-inch rim diameter, but width guidance is not identical across products.

That variation is why wheel measurement should come before committing to a specific tire on a 1933 Packard. A correct nominal size for the car does not automatically mean every product in that size is equally appropriate for every wheel. Measuring the actual rim and comparing it to the selected tire's approved range helps avoid sidewall shape issues and keeps the fit closer to what the manufacturer intended for that particular tire casing.

The listed 1933 Packard products are prewar-style bias-ply tires, but tube marking is not consistently shown in the available size descriptions. That means inner-tube use should be confirmed against the specific tire's sidewall marking and the wheel type on the car rather than assumed from size alone. On an original 1933 Packard wheel, tube fitment is often part of the broader wheel-and-tire setup conversation because many collector cars from this period were designed around tube-type service.

The practical step is to check the selected tire's construction details and inspect the actual wheels before final installation. If your 1933 Packard still uses original-style rims, condition at the bead seat and valve area matters just as much as the tire itself. A marque specialist or experienced vintage tire installer can help confirm whether tubes, flaps, and valve hardware should be part of the setup for your particular wheels.

Original 1933 Packard wheels can only be shared between both listed sizes if the wheel belongs to the correct model group and falls within the selected tire's rim-width requirement. Both 700-17 and 750-17 use 17-inch rim diameter, so there is diameter compatibility across the year. The remaining issue is width, since listed products span different approved rim widths depending on the exact tire. A 17-inch wheel alone does not make both sizes equally suitable.

For a 1933 Packard owner, that means the question is less about year-wide interchange and more about the actual wheels on the specific car. An 8 Cyl. Packard should stay with 700-17 fitment, while a 12 Cyl. Packard should stay with 750-17 fitment unless a specialist-guided change is part of a known historical setup. Confirming wheel width before installation keeps the tire shape, mounting, and appearance aligned with the intended application.

A 1933 Packard should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber. Bias-ply tires benefit from clean floors, stable air pressure, and periodic rolling so the car does not rest on one contact patch for long periods. If the Packard will sit for an extended season, some owners also use tire cradles or support the vehicle to reduce static loading.

Those steps matter because collector cars often age their tires through time and storage conditions more than through mileage. A large, heavy prewar Packard can develop flat-spotting if left motionless too long, and sidewalls can dry out faster in poor storage environments. Good storage habits preserve ride quality, reduce cosmetic cracking, and make the car more pleasant to return to service when driving season arrives.

Tires on a 1933 Packard should be judged more by age, condition, and storage history than by tread wear alone. For collector vehicles, five to seven years is a sensible point for careful evaluation, and around ten years is when replacement should be strongly considered even if the tires still look usable. The DOT date code, when present on the tire, helps establish age, but visual condition and how the car has been stored remain just as important.

That approach fits the way many prewar Packards are used: occasional tours, local events, and long stationary periods between outings. A tire can retain plenty of tread and still become less trustworthy because of aging rubber, internal deterioration, or repeated heat cycles over time. Regular age tracking prevents a handsome restoration from staying on old tires simply because the car has not been driven enough to wear them down.

Tires on a 1933 Packard should be inspected before every drive and again before any longer outing or tour. Look for sidewall cracking, cuts, tread separation, bulges, uneven wear, and signs of pressure loss. Valve stems deserve attention as well, especially on an older collector-car wheel and on any setup where tube service may be part of the installation. A spare tire should be checked with the same care as the four on the ground.

Frequent inspection is especially important on a prewar Packard because the car may spend weeks or months parked between drives, giving age-related issues time to develop quietly. A short pre-drive walkaround can catch problems before they turn into a roadside failure. It is one of the simplest ways to protect the car, preserve the restoration, and make each drive feel more relaxed and predictable.

A 1933 Packard 12 Cyl. would have been fitted with bias-ply tires in keeping with standard practice for the period, and the size associated here is 750-17. That aligns with how senior American luxury cars of the early 1930s were equipped, using tall bias-ply tires on large-diameter wheels. Original-equipment branding could vary by market, coachwork, or historical circumstances, so the most reliable point for authenticity is matching the correct size, construction type, and era-appropriate sidewall appearance.

For a judged restoration, start with 750-17 bias-ply fitment and then verify any market- or body-specific expectations through Packard club resources, factory literature, or marque specialists. That is especially worthwhile on twelve-cylinder Packards because details of presentation often matter as much as broad correctness. Even when a tire is the right size, a sidewall style that looks too modern or out of character can change the visual authenticity of the finished car.

Correct tire fitment does matter when showing a 1933 Packard, particularly because these cars are judged within a period where visual authenticity is closely watched. Size, construction type, and sidewall style all affect whether the car looks appropriate to the era. On a prewar Packard, using the wrong model-specific size or a sidewall treatment that conflicts with the car's presentation can stand out quickly to knowledgeable observers even before they examine finer restoration details.

Owners preparing a show car should treat the tires as part of the restoration's overall correctness rather than as a separate maintenance item. A 12 Cyl. Packard should present on 750-17 bias-ply tires, and an 8 Cyl. Packard should present on 700-17 bias-ply tires, with sidewall style selected to suit the car's intended historical look. Event-specific judging rules can vary, so marque clubs and concours organizers remain the best final check before a major showing.

For the 1933 Packard 8 Cyl., both Firestone Balloon and Ensign B5 are offered in 700-17, but their listed details differ. Firestone Balloon appears in Blackwall, Double-Whitewall, and Wide Whitewall forms, with 4-inch rim width and a listed maximum load of 1480 pounds at 36 psi where stated. Ensign B5 appears as a Blackwall tire with a 3.5 to 4.0-inch rim-width range and a listed maximum load of 1,901 pounds at 36 psi. All are bias-ply options built in period-style sizing.

That makes the choice partly visual and partly wheel-related on a 1933 Packard 8 Cyl. If you want whitewall presentation, Firestone Balloon offers those period luxury looks, while Ensign B5 provides a blackwall alternative with its own stated rim-width and load characteristics. Comparing the actual wheel width on the car to each product's approved range is the best way to sort the suitable choices without compromising fitment for the sake of appearance alone.

1933 Packard tires can be suitable for highway use when they are the correct size for the model, in sound condition, properly inflated, and used within the capabilities of a prewar automobile. The available fitments here are bias-ply tires, and no explicit speed ratings are shown for these products. On a car of this age, overall roadworthiness depends at least as much on brake condition, steering, suspension, wheel integrity, and general mechanical health as it does on the tire itself.

For real-world driving, a well-prepared 1933 Packard should be treated as a vintage touring car rather than driven like a modern sedan. Keep speeds reasonable, allow longer stopping distances, and pay close attention to how the car feels at speed, especially after storage. A fresh, correctly fitted set of tires is an important part of that preparation, but the entire chassis and braking system should be evaluated before expecting comfortable long-distance road performance.

Inflation pressure on a 1933 Packard depends on the exact tire selected and the vehicle's original recommendations. Among the listed products, examples include 700-17 tires rated at 1480 pounds at 36 psi and 1,901 pounds at 36 psi, while 750-17 products include listings at 1646 pounds at 36 psi and 1870 pounds at 40 psi. Those are tire capacity figures, not a universal instruction to run every 1933 Packard tire at the same pressure under all conditions.

The right way to approach inflation is to start with the Packard owner's guidance or recognized marque references for the car, then compare that with the selected tire's rated pressure information. Do not transfer a pressure figure from 700-17 to 750-17 or from one product series to another just because the wheel diameter matches. Proper pressure affects ride, steering feel, wear pattern, and overall confidence on a heavy prewar luxury car.

Before a longer drive in a 1933 Packard, inspect all five tires for cracking, cuts, bulges, weathering, and uneven wear, and confirm that each tire is holding the intended pressure. Check valve stems carefully, and if your wheel-and-tire setup uses tubes, make sure the entire assembly has been serviced correctly. The spare should be usable, not just present. Wheel fasteners, jack equipment, and basic roadside tools also deserve attention on a prewar touring car.

Tires are only one part of the preparation, but they are the part in constant contact with the road, so they deserve a deliberate inspection before any distance event. On a 1933 Packard, it also makes sense to review brakes, cooling, steering play, and fluid levels before departure. That combination of tire inspection and broader mechanical preparation helps the car feel calmer, track better, and deliver the kind of dependable motoring these Packards were famous for in their day.
