The 1929 Packard 633 Series came from an era when Packard was firmly established as one of America’s premier luxury marques, and tire choice was closely tied to both road manners and presentation. Owners restoring or maintaining one today usually care as much about correct visual character as they do about safe, usable fitment. This Packard 633 Series uses bias-ply tires, with 32X6.75 and 700-20 appearing within the covered fitment. The available 700-20 options include blackwall, wide whitewall, and double-whitewall treatments across Firestone, BFGoodrich, and Denman lines. That makes wheel confirmation especially important before choosing a tire for touring use or a restoration-oriented appearance.
Which Tire Size Is Right for The 1929 Packard 633 Series
The 1929 Packard 633 Series uses two primary tire sizes, and the first step is confirming which wheel setup is actually on the car. Both fitments are bias-ply, but they do not share the same rim diameter, so identifying the exact wheel size matters before comparing sidewall style, tire series, or restoration-oriented appearance.
32X6.75 is an antique diameter-by-section size, meaning the first number refers to the tire’s approximate overall diameter and the second identifies its section width. It is a bias-ply fitment that reflects early sizing practice from the late 1920s, when tire dimensions were often described by outside diameter rather than by a modern rim-first format. For a Packard owner, this size calls for careful wheel verification because it differs fundamentally from the 700-20 format used elsewhere on the same model line. It is best evaluated as part of an authentic period-style setup rather than assumed interchangeable with later numeric sizes.
700-20 is a numeric bias-ply size in which the leading number represents nominal section width and the final number identifies the rim diameter in inches. On the 1929 Packard 633 Series, it is the more fully supported fitment in available tires, with choices from Firestone, BFGoodrich, and Denman. Sidewall treatments include blackwall, wide whitewall, and double-whitewall, and the available tire series range from traditional passenger-car balloon styles to truck-oriented designs. That makes 700-20 the size where appearance, intended use, and wheel-width compatibility become the main buying decisions.
The covered sub-model uses the same pair of bias-ply tire sizes, so the main fitment question is not trim level but wheel setup. Checking the actual rim diameter on the car is still essential because these two sizes do not share the same wheel requirement.

Tire Size & Fitment
What tire size fits a 1929 Packard 633 Series?
The 1929 Packard 633 Series uses two primary bias-ply tire sizes: 32X6.75 and 700-20. Those sizes are not just alternate ways of writing the same fitment, because they correspond to different wheel setups and reflect different vintage sizing systems.
Choosing between them starts with the car itself rather than the model name alone. A Packard that still has its original-style wheel configuration may differ from one that has been changed during restoration or long-term service, so the wheel diameter and tire markings on the car should be checked before ordering a replacement.
What size rim does a 1929 Packard 633 Series use?
Rim size depends on which tire size is on the car. The 32X6.75 fitment is paired with a 5.0-inch rim diameter, while the 700-20 fitment uses a 20-inch rim diameter.
That difference makes wheel confirmation the most important step in the entire fitment process. A buyer should inspect the wheel and existing tire together, especially on a collector car that may have seen restoration work or parts changes over the decades, because selecting by vehicle name alone can easily put the focus on the wrong tire size.
Does the 1929 Packard 633 Series 8 Cyl. use the same tire size?
The 1929 Packard 633 Series 8 Cyl. uses the same pair of primary tire sizes associated with this model: 32X6.75 and 700-20, both in bias-ply construction. The sub-model itself does not narrow that down to one universal tire size.
That means the real fitment decision is still tied to the wheel setup on the individual car. A Packard owner should verify which diameter wheel is present and then choose the tire within that fitment, rather than assuming every 633 Series 8 Cyl. will be wearing the same size after nearly a century of use, restoration, and maintenance.
Choosing the Right Tire
What should I consider when choosing a 700-20 tire for a 1929 Packard 633 Series?
Start with the role the car will play. A 700-20 tire for a 1929 Packard 633 Series may be selected for a traditional passenger-car look, a whitewall-oriented restoration presentation, or a more utilitarian setup, and the available choices differ by tire series, sidewall treatment, load specification, and rim-width range.
Appearance matters on a late-1920s Packard, but wheel compatibility matters just as much. Comparing the actual wheel width on the car against the tire’s stated rim-width range helps narrow the choices, and that check should happen before deciding between Firestone Balloon, Silvertown Classic Bias Ply, or truck-oriented alternatives.
What sidewall styles are available for 1929 Packard 633 Series tires?
For 700-20 fitment, the available sidewall styles include blackwall, wide whitewall, and double-whitewall. Those choices change the overall presentation of the 1929 Packard 633 Series quite a bit, especially on a vehicle where tire sidewall style is a highly visible part of the finished look.
A blackwall setup gives a more restrained appearance, while wide whitewall and double-whitewall treatments lean more strongly into restoration-oriented visual character. The right choice depends on how the car is being finished and driven, and owners chasing exact historical detail should compare the tire style against marque references for their specific car.
What brands offer tires for the 1929 Packard 633 Series?
The available 700-20 tires for the 1929 Packard 633 Series come from Firestone, BFGoodrich, and Denman. Those brands appear across different tire series and sidewall treatments, so the selection is broader than a single look or usage type.
Brand should be considered alongside the rest of the specification rather than as a stand-alone decision. On a car like this, the buyer usually gets the best result by first confirming the correct size and wheel, then comparing whether a given brand’s available series, sidewall style, and rim-width requirements match the Packard’s intended appearance and use.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Packard 633 Series?
A period-style 1929 Packard 633 Series should begin with the correct primary tire size for the wheel setup already on the car, either 32X6.75 or 700-20, and in bias-ply construction. From there, the most relevant period-style choices appear in the 700-20 offerings, which include traditional balloon-style and classic bias-ply presentations.
The final choice depends on whether the goal is a formal touring look, a restrained blackwall presentation, or a brighter whitewall appearance. Buyers pursuing exact restoration accuracy should compare the tire’s sidewall treatment and overall visual character with photos, marque-club guidance, and vehicle-specific historical references before making a final selection.
Does correct tire fitment matter for a 1929 Packard 633 Series restoration?
Correct tire fitment matters a great deal on a 1929 Packard 633 Series because tire size, rim diameter, and sidewall style all influence how the car sits and how authentic the finished presentation appears. With both 32X6.75 and 700-20 associated with this model, restoration work should begin by confirming the actual wheel arrangement.
A tire that looks appropriate in isolation can still be wrong for the wheel or for the visual balance of the car. Verifying the wheel size first, then choosing the proper bias-ply tire and sidewall treatment, helps preserve the Packard’s proportion and avoids undermining otherwise careful restoration work.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Packard 633 Series?
Yes. Modifications can affect tire fitment on a 1929 Packard 633 Series, especially if the car has replacement wheels, altered suspension components, brake changes, or body work that changes available clearance. That matters even more here because the model is associated with two very different tire and rim formats.
A buyer should verify the actual wheel diameter and width on the car before selecting tires, then check steering and fender clearance with the chosen fitment in mind. Collector cars often carry changes made decades apart, so even a well-restored Packard deserves an on-car inspection instead of relying on assumptions.
What should I inspect before driving a 1929 Packard 633 Series on new tires?
Before road use, inspect the wheels for damage, confirm that the tire size matches the wheel setup, and check inflation, mounting condition, and overall clearance. It is also wise to look at the rest of the chassis, including steering and suspension condition, because a vintage Packard places a lot of emphasis on smooth, stable running.
The first miles on new tires are a good time to watch for rubbing, uneven stance, or any sign that the tire and wheel combination is not settling correctly. Rechecking air pressure and fasteners after initial driving helps establish a reliable baseline, particularly on a car that may spend long periods in storage.
How should 700-20 tires on a collector 1929 Packard 633 Series be maintained?
700-20 tires on a collector 1929 Packard 633 Series should be maintained with regular pressure checks, visual inspection for sidewall cracking or cuts, and periodic review of tread condition even if the car is driven sparingly. Collector use often ages tires by time and storage exposure as much as by mileage.
Storage habits matter nearly as much as maintenance on the road. Keeping the Packard away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and occasional inspection of wheel condition and valve hardware can catch problems early before a touring drive or show-season outing.
