1929 Oakland AA Tires

The 1929 Oakland AA uses two primary bias-ply tire sizes: 29X5.50 and 550-19. The covered 1929 Oakland AA 6 Cyl. sub-model is associated with both sizes, so either one may be relevant depending on the wheel and tire setup currently on the car.

That makes verification especially important before replacing old tires on a prewar vehicle. Check the size molded into the existing tire, confirm that the wheel is a 19-inch rim where applicable, and inspect whether the car still carries its intended wheels or has been changed over the years. On an older restoration, matching the tire to the actual wheel setup matters more than assuming every surviving car still wears the same configuration.

The 1929 Oakland AA uses a 19-inch rim with its 550-19 tire fitment. That rim diameter is the key wheel measurement tied directly to the numeric bias-ply size, and it is the critical dimension to confirm before ordering replacement tires for a car from this era.

Wheel diameter alone is not the whole story on an older vehicle, though. Rim width and the actual wheel style on the car should also be checked, especially if the Oakland has gone through a restoration long ago or has had wheels swapped since new. A tire marked for a 19-inch rim still needs to match the wheel's width range and the car's present-day setup.

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 its nominal section width. That format is typical of earlier vehicles and differs from later numeric bias-ply sizes that identify rim diameter directly in the size code.

For a 1929 Oakland AA owner, that means the size should be interpreted carefully rather than treated like a modern metric marking. Since this format does not spell out rim diameter in the same way as 550-19, the best next step is to inspect the wheel and any existing tire markings together. That helps prevent ordering a period-looking tire that does not match the wheel currently on the car.

Start with the basics: correct size, bias-ply construction, and compatibility with a 19-inch wheel. In 550-19 for the 1929 Oakland AA, the available BFGoodrich Silvertown Classic Bias Ply options share the same core size and construction, so the main differences come down to sidewall treatment and wheel-width suitability.

That means the choice is often driven by how the car is being presented and used. A blackwall gives a more restrained, utilitarian look, while a wide whitewall creates a more formal restoration-oriented appearance. It also helps to compare the wheel's width against the tire's intended rim range and to inspect the suspension, steering, and body clearances if the car has not been driven on fresh tires in some time.

In 550-19 for the 1929 Oakland AA, available sidewall styles include Blackwall and Wide Whitewall. Both are bias-ply tires in the BFGoodrich Silvertown Classic Bias Ply line, so the decision is less about changing fitment and more about choosing the presentation that suits the car.

Sidewall style has a major visual effect on a prewar automobile. A blackwall typically looks simpler and more understated, while a wide whitewall creates a brighter, more formal period impression. Since appearance preferences can vary from preservation to full restoration, it is worth looking at the car's trim, paint, and overall finish before settling on a sidewall treatment.

The available 550-19 tires for the 1929 Oakland AA come from BFGoodrich. Those products are part of the Silvertown Classic Bias Ply series and cover both blackwall and wide whitewall presentations in the same general period-style construction.

With a single brand represented in the available 550-19 options, the buying decision shifts toward style and specification details rather than brand comparison. Focus on whether the tire matches the wheel on the car, whether the sidewall appearance suits the restoration, and whether the vehicle will be shown, toured lightly, or simply kept roadworthy with a traditional prewar look.

A period-style 1929 Oakland AA should stay with one of its primary bias-ply fitments, either 29X5.50 or 550-19, depending on the actual wheel and tire setup on the car. Within the currently available 550-19 options, the BFGoodrich Silvertown Classic Bias Ply line keeps the traditional construction and overall visual character expected on a late-1920s automobile.

The final choice depends on how closely the car is being restored and how it will be presented. Some owners prefer the simpler look of a blackwall, while others want the more formal appearance of a wide whitewall. If exact historical accuracy is important, compare the tire choice against period photos, marque-club references, or restoration documentation tied specifically to the individual car.

Correct tire fitment matters a great deal on a 1929 Oakland AA because the tire strongly influences stance, wheel appearance, and the overall period impression of the car. Using one of the proper primary bias-ply sizes helps preserve the proportions and visual character that belong on a late-1920s Oakland.

Fitment also affects more than looks. The wheel diameter, rim width, and tire construction all need to work together, especially on an older restoration that may have seen parts changes over the decades. Even when a tire appears visually close, confirming the wheel setup first helps avoid clearance issues or a mismatched look that can distract from an otherwise carefully presented prewar car.

Yes, modifications can affect tire fitment on a 1929 Oakland AA even when the tire size seems correct on paper. Wheels may have been changed, rim widths can differ from original-style dimensions, and suspension or brake work over the years can alter the space available around the tire.

That is why an older car should be inspected as it sits now, not just by model name. Check wheel diameter, measure wheel width, and look at fender, steering, and suspension clearance before replacing tires. A surviving prewar car may have a very different setup than expected, and the right tire choice depends on the actual hardware currently under the car.

Before driving a 1929 Oakland AA on new tires, inspect the wheels for damage or corrosion, confirm the rim dimensions, and make sure the tires are seated and inflated properly. It also helps to check steering components, suspension condition, and brake operation so the car is not relying on fresh tires to mask unrelated mechanical issues.

A short, cautious road test is the smart next step once everything is mounted. Listen for rubbing, watch for steering pull, and recheck air pressure after the first drive. On a prewar car that may have spent long periods parked, even basic items such as wheel fastener condition and bearing health deserve attention before asking the car to carry new tires at road speed.

550-19 bias-ply tires on a collector 1929 Oakland AA should be kept clean, properly inflated, and inspected regularly for cracking, cuts, bulges, tread wear, and slow air loss. Because collector cars often see limited use, age and storage conditions can matter just as much as miles when evaluating tire condition.

Storage habits make a real difference with an older vehicle. Keep the car away from prolonged sunlight, excessive heat, moisture, and ozone sources, and move it occasionally so the tires are not supporting the same contact patch for extended periods. Before any longer outing, inspect each tire closely and verify pressure rather than assuming low annual mileage means the tires are automatically road-ready.
