The 1929 Hupmobile A comes from a period when American cars were moving into faster, more comfortable road use, yet still depended on tall, narrow bias-ply tires that shaped both ride quality and appearance. On a car like this, tire choice affects more than simple fitment; it influences stance, visual authenticity, and how the car presents at the curb. The 1929 Hupmobile A uses bias-ply sizing in 29X5.50 and 550-19, both tied to a 19-inch wheel fitment. Available choices include traditional blackwall and wide whitewall treatments in BFGoodrich's Silvertown Classic Bias Ply line. For a restoration-minded owner, the key is confirming which period-style size notation matches the wheel and presentation goal.
Which Tire Size Is Right for The 1929 Hupmobile A
The 1929 Hupmobile A uses two primary tire size expressions, and both are bias-ply fitments associated with a 19-inch wheel setup. Because the covered 6 Cyl. sub-model uses both, the real decision is less about vehicle trim and more about understanding the sizing format, confirming the wheel, and choosing the sidewall appearance that best suits the car's restoration or driving plans.
A size like 29X5.50 uses an older diameter-by-section format, where 29 refers to the tire's approximate overall diameter in inches and 5.50 refers to its approximate section width. This is a bias-ply fitment typical of late-1920s cars, and it reflects the tall, upright tire proportions associated with the 1929 Hupmobile A. Buyers often encounter this size as part of period-correct tire language rather than a modern sizing system. It is most useful when the goal is to match antique tire notation closely and keep the vehicle's overall presentation in line with its era.
The 550-19 size is a numeric bias-ply designation in which 550 indicates an approximate 5.50-inch nominal section width and 19 identifies the rim diameter in inches. For the 1929 Hupmobile A, this size opens the door to actual product choice within the correct vintage format, including BFGoodrich Silvertown Classic Bias Ply options in blackwall and wide whitewall styles. Product specifications also center on narrow vintage wheel widths appropriate to the period. This size is the practical choice when the owner wants a clearly supported 19-inch bias-ply replacement with traditional appearance options.
Sub-model fitment is straightforward here, as the covered 1929 Hupmobile A sub-model shares the same pair of primary bias-ply size notations. Checking the exact sub-model still matters because the buyer should confirm the wheel setup on the car before choosing between antique and numeric size expressions.

Best 1929 Hupmobile A Tires for Sale
Available 550-19 options focus on traditional bias-ply construction in BFGoodrich's Silvertown Classic Bias Ply series. The main comparison points are sidewall style, with blackwall and wide whitewall choices, along with matching the tire to the narrow 19-inch wheel widths used on this application.
These 1929 Hupmobile A tire FAQs focus on the two vintage size formats, 19-inch rim fitment, bias-ply construction, appearance choices, and the basic checks that matter before putting a collector-era car back on the road.
Tire Size & Fitment
What tire size fits a 1929 Hupmobile A?
The 1929 Hupmobile A uses two primary bias-ply tire size notations: 29X5.50 and 550-19. Those two sizes represent the vintage fitment language associated with this model, and 550-19 ties directly to a 19-inch rim diameter.
The practical step is to confirm the wheel on the car before choosing between size expressions. Antique vehicles are sometimes restored, re-wheeled, or mixed with later service parts, so the owner should verify rim diameter and overall wheel condition rather than relying only on what is currently mounted.
What size rim does a 1929 Hupmobile A use?
The 1929 Hupmobile A uses a 19-inch rim with its primary tire fitment. That matches the 550-19 numeric bias-ply size and aligns with the tall, narrow tire proportions expected on a late-1920s passenger car.
Rim diameter is only part of the fitment picture on a collector car. It is also worth checking wheel width, bead-seat condition, and whether the car still carries the correct style of wheel for its tires, especially if the vehicle has been apart for restoration or has been sitting for a long period.
What does 29X5.50 mean on a 1929 Hupmobile A?
On the 1929 Hupmobile A, 29X5.50 is an antique diameter-by-section size. The 29 refers to the tire's approximate overall diameter in inches, while 5.50 refers to the approximate section width, making it a very different format from later numeric or modern metric sizing.
That older notation matters because it helps the buyer interpret what is actually on the car and compare it correctly with other vintage size markings. A 1920s Hupmobile can look similar with different tire labels, but the wheel, overall proportions, and intended period-style appearance still need to be checked carefully.
Choosing the Right Tire
What should I consider when choosing a 550-19 tire for a 1929 Hupmobile A?
Start with the correct size, construction, and wheel compatibility. A 550-19 for the 1929 Hupmobile A is a bias-ply tire built for a 19-inch rim, and available examples in this fitment use narrow vintage rim widths along with period-style sidewall treatments.
After size and wheel fitment are confirmed, the choice becomes more about presentation and use. A blackwall gives a restrained traditional look, while a wide whitewall creates a stronger pre-war visual statement. Tire weight and load specification can also help compare options when the car will see regular touring rather than display use alone.
What sidewall styles are available for 1929 Hupmobile A tires?
The available 550-19 tires for a 1929 Hupmobile A include blackwall and wide whitewall sidewall styles. Both are bias-ply options within the same BFGoodrich Silvertown Classic Bias Ply family, so the visual difference is the main point of comparison rather than a change in construction type.
That sidewall choice has a major effect on how the car reads visually. A blackwall usually suits a more understated restoration, while a wide whitewall gives the car a brighter, more formal period presentation. Matching sidewall style to the vehicle's finish, trim, and restoration intent often matters as much as the size itself.
What tire series are available for the 1929 Hupmobile A?
The available 550-19 products for the 1929 Hupmobile A fall within the BFGoodrich Silvertown Classic Bias Ply series. That keeps the comparison focused, since the series remains the same while sidewall appearance and certain product specifications distinguish one option from another.
With a single series in play, the buyer can concentrate on whether the car needs a blackwall or wide whitewall look and whether the wheel dimensions match the tire's intended rim-width range. On a collector vehicle, that kind of disciplined selection usually matters more than chasing unnecessary variation.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Hupmobile A?
A period-style 1929 Hupmobile A starts with the correct vintage bias-ply sizing language, either 29X5.50 or 550-19 depending on how the wheel setup and restoration are being interpreted. Within supported product choices, a 550-19 bias-ply keeps the car in a traditional construction and appearance category.
The final decision usually comes down to presentation. Blackwall and wide whitewall versions create very different visual impressions, even within the same basic fitment. When exact historical detail matters, it helps to compare the tire choice against period photos, marque references, and the car's own restoration direction rather than relying on appearance alone.
Does correct tire fitment matter for a 1929 Hupmobile A restoration?
Correct tire fitment matters a great deal on a 1929 Hupmobile A because these cars depend on tall, narrow tire proportions for much of their stance and character. Using the proper vintage size format and matching it to the 19-inch wheel preserves the visual balance that defines the car's era.
Fitment also affects more than appearance. The wrong wheel width, an incorrect rim diameter, or a mismatched tire profile can change how the car sits and can complicate mounting or road use. A careful restoration should treat tires as a visible and functional part of the overall vehicle package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Hupmobile A?
Yes, modifications can affect tire fitment on a 1929 Hupmobile A, even when the tire size itself sounds correct. Wheel replacements, altered suspension height, brake conversions, or body repairs around the fenders can all change the space available for a tall vintage bias-ply tire.
A changed vehicle should be measured rather than assumed. Checking wheel diameter, wheel width, steering travel, and clearance at the fender and suspension points is especially important on older cars, where small differences in wheel hardware or restoration work can have a larger effect than expected.
What should I inspect before driving a 1929 Hupmobile A on new tires?
Before driving a 1929 Hupmobile A on new tires, inspect the wheels, valve hardware, and overall mounting condition, then make sure the tires seat properly and hold air consistently. It is also smart to check for brake drag, loose wheel bearings, and any interference that might appear during slow steering movement.
Collector cars often sit longer than modern vehicles, so the first road use should be cautious. Recheck pressure after the initial drive, look again for sidewall or rim issues, and pay attention to vibration, pull, or rubbing. A short local run is a better shakedown than heading straight into a longer trip.
How should 550-19 tires on a collector 1929 Hupmobile A be maintained?
550-19 tires on a collector 1929 Hupmobile A should be kept clean, properly inflated, and inspected regularly for cracking, cuts, bulges, or unusual wear. Because this is a vintage bias-ply fitment, storage habits matter, especially on a vehicle that may spend long periods parked between drives.
Good maintenance also includes protecting the tires from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or compressors. Rolling the car periodically, avoiding long-term underinflation, and checking the tires before each outing helps preserve both appearance and roadworthiness on an infrequently used antique vehicle.
