Oakland AA Tires

Oakland AA uses two listed tire sizes for 1929: 29X5.50 and 550-19. The available 550-19 products fit a 19-inch rim and are built for 2.50 to 3.00 inch rim widths, while 29X5.50 is an older diameter-by-section style where the wheel diameter is not stated in the size code itself.

That means year alone is not enough to choose a tire for Oakland AA. Start by reading the size marking on the existing tire if it is still present, then confirm the actual rim diameter on the wheel before selecting between the antique-style 29X5.50 and the numeric 550-19 fitment.

On Oakland AA, 29X5.50 is an antique diameter-by-section size. The 29 refers to the tire’s overall outside diameter in inches, and the 5.50 refers to nominal section width, so the first number is not the wheel diameter in the way a modern buyer might expect.

That distinction matters because a buyer can easily mistake 29X5.50 for a 29-inch wheel fitment, which it is not. If your Oakland AA carries this style of size marking, verify the wheel separately and compare it with period paperwork, wheel stamping, or guidance from an Oakland specialist before choosing a replacement.

A 1929 Oakland AA can show two listed sizes because the model appears with two different sizing conventions in the same year: 29X5.50 and 550-19. That kind of split usually points to a wheel or equipment difference rather than a simple substitute size in the modern sense.

The practical takeaway is that your Oakland AA needs to be identified by its actual wheel and tire markings, not just by model year. Check the rim diameter first, then compare the tire code on the car to the listed options so you avoid choosing a balloon-era 19-inch tire for a car expecting the antique-format size.

Oakland AA fitments here are bias-ply sizes, and the available 550-19 products are bias-ply construction. For this type of vintage application, a tube is required with the listed non-radial sizes, including the 550-19 balloon-style fitment.

Tube fitment should be treated as part of the tire installation plan rather than an afterthought. Make sure the tube matches the tire size and that the wheel condition is suitable for tube-type service, especially on an older collector car where rust, burrs, or old rim strips can damage a fresh tube quickly.

The correct way to confirm a tire size for a 1929 Oakland AA is to identify the exact size convention already associated with the car and then verify the wheel diameter. Oakland AA is listed with both 29X5.50 and 550-19, and those are not interchangeable labels for the same fitment.

Begin with the wheel itself, since 550-19 specifically uses a 19-inch rim while 29X5.50 does not state the rim diameter in the code. After that, compare what you find against surviving tire markings, period service information, or recognized Oakland reference material so the replacement matches the car’s actual configuration.

Oakland AA tires in the available 550-19 fitment come in two sidewall styles: blackwall and wide whitewall. Both are offered within the BFGoodrich Silvertown Classic Bias Ply line, so the construction and basic fitment stay the same while the visual presentation changes.

That gives a restorer some flexibility depending on the look of the car and the finish standard being pursued. Blackwall is often chosen for a more restrained appearance, while a wide whitewall creates a more formal late-1920s visual statement, so the best choice depends on how your Oakland AA is being preserved or presented.

The available Oakland AA products listed here are from BFGoodrich. Both of the current offerings are 550-19 bias-ply tires, with one blackwall version and one 3.25 inch whitewall version.

Since the brand selection shown for Oakland AA is narrow, confirming the correct size becomes even more important before choosing a sidewall style. If your car uses the alternate 29X5.50 sizing convention, verify that separately rather than assuming the available 550-19 products will suit every 1929 Oakland AA.

The Oakland AA products listed here are in the BFGoodrich Silvertown Classic Bias Ply series. That means the currently available options differ mainly by sidewall appearance rather than by a change in construction family, with both using bias-ply construction in the same 550-19 size.

For a buyer, that simplifies the decision once the correct size has been confirmed. The main choice is whether your Oakland AA should wear a blackwall or a wide whitewall presentation, since both options maintain the same general period-style bias-ply character for the listed 19-inch application.

A stored Oakland AA should be kept in a cool, dry, dark environment with the tires protected from direct sunlight, electric motors, and ozone sources. Bias-ply tires on low-use collector cars also benefit from clean floors, proper inflation, and relief from long periods of full static load when possible.

If the car will sit for extended stretches, move the Oakland AA occasionally to change the tire contact patch or support it in a way that reduces flat spotting without stressing the suspension. Good storage habits matter as much as mileage on a collector tire, especially on a late-1920s car that may spend long intervals parked.

Tires on an Oakland AA should be inspected before every drive and more thoroughly at regular intervals even if the car covers very few miles. On a collector car running bias-ply tires, visual checks should include cracking, bulges, tread separation, sidewall damage, valve condition, and signs of tube or rim issues.

A practical routine is to give the Oakland AA a walk-around inspection each time it comes out of storage, then schedule periodic hands-on checks that include inflation pressure and wheel hardware. Low annual mileage can hide age-related deterioration, so condition and time matter more than tread wear alone on a car like this.

Tires on an Oakland AA should be replaced when they show age cracking, stiffness, impact damage, irregular shape, tread separation, repeated air-loss problems, or any condition that suggests the casing is no longer sound, even if the tread still looks usable. On collector vehicles, age and storage history are often more important than miles driven.

That is especially true for a bias-ply fitment on a late-1920s automobile, where the tire’s structural condition affects both safety and drivability. If a tire’s age is uncertain, or if it has spent long periods under load or exposed to harsh storage conditions, specialist inspection is the right next step before the Oakland AA goes back on the road.

Oakland AA is associated here with two period-appropriate size conventions for 1929: 29X5.50 and 550-19. The currently available products are BFGoodrich Silvertown Classic Bias Ply tires in 550-19, but that does not mean every Oakland AA used the same wheel and tire arrangement.

For an accurate restoration, the best approach is to verify the exact equipment on your particular Oakland AA through original paperwork, wheel markings, and marque references. That matters because a correct restoration is shaped not only by the year, but also by the specific wheel and size convention the car was built or later maintained with.

Correct tire fitment can absolutely affect both the presentation and judged authenticity of an Oakland AA. Size, sidewall treatment, stance, and overall period appearance all influence whether the car looks historically consistent, particularly on a vehicle from the late 1920s where wheel and tire proportions are visually prominent.

For owners concerned with show results or preservation value, the key is to match the Oakland AA’s actual wheel equipment and restoration goal rather than choosing only by appearance. Marque clubs, period photography, and event judging standards are often the best references when deciding between alternate listed sizes or between blackwall and whitewall presentation.

Oakland AA has available 550-19 tires in both blackwall and wide whitewall form. Either can suit a late-1920s restoration depending on the character of the car, the trim level of the build, and the visual standard the owner is trying to achieve.

If your Oakland AA is being restored for strict authenticity, use the sidewall style that matches period evidence for that specific car rather than choosing by preference alone. If the goal is a strong era-correct appearance for touring or exhibition, the decision often comes down to whether you want a more restrained blackwall look or a more formal whitewall presentation.

Properly fitted modern-production bias-ply tires in the correct size can be suitable for public-road use on an Oakland AA when the entire vehicle is mechanically sound and used within the limits of a late-1920s automobile. Tire choice is only one part of that equation, since brakes, steering, suspension, wheels, and inflation all affect real-world safety.

An Oakland AA should be approached as a collector car with older design characteristics, not as a modern traffic appliance. Before regular road use, make sure the tire size matches the wheel exactly and have the car evaluated as a complete system so the driving plan fits the car’s age, handling, and braking capability.

Before driving an Oakland AA, check tire inflation, visible sidewall condition, tread condition, valve stems, wheel security, and any signs of tube-related air loss or rim trouble. On a vintage bias-ply setup, it is also wise to look for flat spotting after storage and any bulges or distortions that developed while the car was parked.

A short pre-drive routine helps catch the problems that matter most on a low-use collector car. Once the tires are confirmed, give the Oakland AA a cautious initial drive to feel for pull, vibration, or unusual steering response, since those early signs often reveal fitment, inflation, or chassis issues before they become more serious.

An Oakland AA should be driven at moderate, conservative speeds that respect the car’s original engineering and the behavior of bias-ply tires. Even with fresh tires, a late-1920s vehicle does not respond like a modern car in emergency braking, cornering, or lane-change situations.

The sensible approach is to drive the Oakland AA at speeds appropriate to road conditions, traffic, and the car’s mechanical state rather than trying to keep up with fast modern flow. Smooth inputs, extra following distance, and avoidance of abrupt maneuvers are just as important as the tire itself when operating a collector car of this era.
