The 1929 Gardner 120 Series comes from a short-lived but respected American luxury marque known for building refined automobiles during the late pre-war era. For owners of these cars today, tire choice is part preservation, part practical road-readiness, because the visual character and driving feel depend heavily on using the proper vintage sizing. The 1929 Gardner 120 Series uses bias-ply fitments in 29X5.50 and 550-19 on a 19-inch rim. Within that fitment, the available choices center more on sidewall presentation than construction, with Blackwall and Wide Whitewall options in 550-19. The key is matching the correct size format to the wheel and the restoration goal before putting the car back on the road.
Which Tire Size Is Right for The 1929 Gardner 120 Series
The 1929 Gardner 120 Series uses two primary bias-ply size expressions, and both point to a 19-inch fitment. Because the 8 Cyl. sub-model carries both sizes, the first step is confirming how the tire is marked on the car now and making sure the wheel matches the intended vintage sizing format. Once that is settled, the real decision is usually appearance, especially Blackwall versus Wide Whitewall in 550-19.
A 29X5.50 size uses an older diameter-by-section format, where the first number is the tire’s approximate overall diameter in inches and the second number is its nominal section width. On the 1929 Gardner 120 Series, this is a bias-ply fitment tied to the car’s early luxury-era wheel and tire presentation. Buyers familiar only with later numeric sizes should recognize that this format describes the tire differently, even though it belongs in the same vintage fitment conversation. It is worth checking the wheel marking and existing tire notation carefully before choosing between this format and 550-19.
A 550-19 tire is a numeric bias-ply size, with 5.50 representing nominal section width and 19 identifying the rim diameter in inches. For the 1929 Gardner 120 Series, this size opens the clearest product choice, including BFGoodrich Silvertown Classic Bias Ply tires in both Blackwall and 3.25-inch Wide Whitewall form. Those choices matter more to most buyers than construction, since the fitment remains bias-ply either way. This size is especially useful for owners balancing road use with a restoration-oriented appearance and wanting a traditional 19-inch vintage tire option.
Sub-model fitment is straightforward here, because the covered 8 Cyl. version uses the same pair of bias-ply tire sizes. Checking the exact sub-model still matters so the tire choice stays aligned with the wheel and size format already on the car.

1929 Gardner 120 Series 8 Cyl.
The 1929 Gardner 120 Series 8 Cyl. uses the same two bias-ply fitments, 29X5.50 and 550-19, tied to a 19-inch wheel setup. That means tire selection is less about changing sizes and more about confirming the wheel, preserving the proper vintage look, and choosing the sidewall presentation that suits the car.
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.

Owners of a 1929 Gardner 120 Series usually need clarity on vintage tire sizing, 19-inch wheel fitment, sidewall appearance, and what to inspect before returning a collector car to road use.
Tire Size & Fitment
What tire size fits a 1929 Gardner 120 Series?
The 1929 Gardner 120 Series uses two primary bias-ply tire sizes: 29X5.50 and 550-19. Those two markings reflect vintage sizing conventions used on the same 19-inch fitment, and the covered 8 Cyl. sub-model is associated with both sizes.
The practical step is to confirm what size marking is on the car now and verify the wheel before ordering tires. Early vehicles are often restored or re-equipped over time, so matching the tire notation to the actual wheel setup helps avoid confusion between antique diameter-based sizing and later numeric bias-ply sizing.
What size rim does a 1929 Gardner 120 Series use?
The 1929 Gardner 120 Series uses a 19-inch rim with its primary tire fitments. That rim diameter aligns directly with the 550-19 size and also with the vehicle’s 29X5.50 fitment context, even though the two sizes are written in different vintage formats.
Rim diameter should be checked on the wheel itself before selecting tires, especially on a pre-war collector car that may have seen wheel changes during its life. For 550-19 products, rim-width compatibility also matters, with available options built for wheels in the 2.50- to 3.00-inch range.
Does the 1929 Gardner 120 Series 8 Cyl. use the same tire size?
Yes. The 1929 Gardner 120 Series 8 Cyl. is associated with the same two primary bias-ply fitments used on this vehicle page: 29X5.50 and 550-19. That makes sub-model fitment relatively straightforward compared with later vehicles that split tire sizes by trim or package.
Even with shared sub-model fitment, the buyer still needs to verify how the existing wheel and tire are marked. On an older restoration, the most useful check is whether the car is currently set up around the antique diameter-by-section format or the numeric 550-19 format before choosing a replacement tire.
Choosing the Right Tire
What should I consider when choosing a 550-19 tire for a 1929 Gardner 120 Series?
Start with the basics: correct 550-19 sizing, bias-ply construction, and a 19-inch wheel. For this Gardner, the main available product differences are sidewall presentation within the BFGoodrich Silvertown Classic Bias Ply line, including Blackwall and 3.25-inch Wide Whitewall versions.
The best choice depends on how the car is being presented and driven. A more understated restoration may lean toward Blackwall, while a more formal period-style appearance may call for Wide Whitewall. Wheel width matters too, so compare the tire’s rim-width requirement against the actual wheel before making a final decision.
What sidewall styles are available for 1929 Gardner 120 Series tires?
The available 550-19 options for the 1929 Gardner 120 Series include both Blackwall and Wide Whitewall sidewall styles. Both are bias-ply tires in the same BFGoodrich Silvertown Classic Bias Ply series, so the visual presentation changes while the basic construction and rim diameter remain consistent.
Sidewall style has a strong effect on how a pre-war luxury car looks at rest and on the road. Buyers usually choose between a cleaner, simpler Blackwall appearance and a more formal Wide Whitewall presentation, while keeping the size, wheel compatibility, and overall restoration direction in line with the car.
What tire series are available for the 1929 Gardner 120 Series?
The available 550-19 products for the 1929 Gardner 120 Series are in the BFGoodrich Silvertown Classic Bias Ply series. That means the visible variation is not a change between multiple series, but a choice within the same vintage-style family using different sidewall treatments.
This simplifies the selection process because the comparison is focused on presentation rather than sorting through unrelated product types. Once size and wheel compatibility are confirmed, the buyer can concentrate on whether the car’s intended use and visual goal are better served by a Blackwall or Wide Whitewall tire.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Gardner 120 Series?
A period-style 1929 Gardner 120 Series should begin with one of its proper bias-ply fitments, either 29X5.50 or 550-19, depending on the wheel setup and the tire notation being followed. Staying within those vintage size formats preserves the car’s overall stance and traditional visual character.
Appearance then becomes the main decision. In 550-19, Blackwall and Wide Whitewall choices create noticeably different presentations while keeping the same general fitment approach. When exact restoration originality matters, it is wise to compare the tire choice with marque references, period photos, and vehicle-specific historical documentation.
How does tire construction affect the appearance of a restored 1929 Gardner 120 Series?
On a restored 1929 Gardner 120 Series, bias-ply construction plays a major role in maintaining the car’s traditional pre-war appearance. The vehicle’s primary fitments are bias-ply sizes, so the tire shape, sidewall presence, and overall visual impression remain consistent with an early luxury automobile.
Construction also influences how the car reads to knowledgeable enthusiasts, even before sidewall style is considered. A Blackwall treatment gives a more restrained look, while a Wide Whitewall adds a more formal presentation. Matching construction and sidewall style to the restoration goal usually matters as much as getting the size right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Gardner 120 Series?
Yes. Any change to the wheels, suspension, ride height, brake components, or body clearances can affect tire fitment on a 1929 Gardner 120 Series. That matters even when staying with a proper vintage size, because older cars often carry replacement wheels or restoration-era changes that are not obvious at first glance.
A careful check should include wheel diameter, wheel width, tire-to-fender clearance, and steering clearance at full lock. On a car of this age, it also helps to confirm that the wheel still matches the intended 19-inch fitment and that no previous modification has altered the space available around the tire.
What should I inspect before driving a 1929 Gardner 120 Series on new tires?
Before road use, inspect the wheel condition, confirm proper tire pressure, and look over the surrounding chassis for anything that could affect clearance or tire wear. On a collector car like a 1929 Gardner 120 Series, it is also smart to check for loose hardware, brake drag, and uneven wheel alignment behavior.
The first few miles should be treated as a shakedown rather than a long tour. Recheck inflation, watch for any rubbing during turns, and inspect the tires for unusual scuffing or air loss after the initial drive. That extra caution is especially important when the car has been stored, restored, or recently reassembled.
How should 550-19 tires on a collector 1929 Gardner 120 Series be maintained?
550-19 tires on a collector 1929 Gardner 120 Series should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long exposure to sun, moisture, and ozone sources. Collector vehicles that sit for extended periods still need routine tire checks even when mileage is low.
Regular inspection matters because age and storage conditions can affect a vintage tire long before the tread appears worn. Moving the car periodically, maintaining a clean dry storage space, and checking for slow air loss help preserve both tire condition and road readiness between outings.
