In the early Depression-era market, 1933 Pontiac occupied an important middle ground, offering more presence and refinement than many low-priced cars while still appealing to practical buyers who wanted style and value. The eight-cylinder Pontiac of this period reflected the brand’s push toward smoother power and a more upscale feel without moving into true luxury territory. For 1933 Pontiac, the tire question is refreshingly straightforward: one model and one tire size, 550-17, carried the full fitment. The real choice is not between different sizes, but between sidewall appearances and the kind of restoration character you want your 1933 Pontiac to present before selecting a tire.
Which Tire Size Is Right for Your 1933 Pontiac
One tire size is available for 1933 Pontiac, and it is shared across the full model range covered here. That means the main decision is not fitment between multiple sizes, but choosing the right bias-ply tire presentation for the car’s restoration style and intended use. Understanding that distinction before choosing a product saves time and helps match the tire to the car.
Year(s): 1933|Fit(s): 8 Cyl.|Construction: Bias Ply|Rim: 17 in
550-17 is a numeric bias-ply size, with 5.50 indicating nominal section width and 17 indicating the wheel diameter in inches. BFGoodrich offers this size in Blackwall, Wide Whitewall, and Double-Whitewall versions, all in bias-ply construction. Buyers restoring a 1933 Pontiac for period appearance will typically stay with this size, then choose the sidewall look that best matches the car’s finish, trim level, and presentation goals.
One Pontiac model core is covered for 1933. All fitments here use the same 550-17 tire size, so model selection does not change the tire size itself; the more meaningful choice is how authentic or formal you want the finished look to appear through sidewall styling. Select the model below for model-specific fitment history and products.
1933 Pontiac 8 Cyl.
The 1933 Pontiac 8 Cyl. represented Pontiac’s effort to offer a smoother, more substantial driving experience in a difficult economic period, blending practical value with a noticeable step up in prestige. Its tires mount on 17-inch wheels, and the shared 550-17 sizing keeps the fitment picture simple while leaving room to tailor the final appearance with blackwall or whitewall styling.
Three products are available across one tire size for 1933 Pontiac vehicles. The 550-17 size includes three BFGoodrich bias-ply options with Blackwall, Wide Whitewall, and Double-Whitewall sidewall styles, so the key step is choosing the appearance that best suits your car.
These FAQs cover how 550-17 sizing works on 1933 Pontiac models, what the numeric bias-ply code means, which sidewall styles are available, and what owners should check when preparing a collector car for storage or road use.
Size Basics & Fitment
What tire sizes fit 1933 Pontiac vehicles?
1933 Pontiac vehicles covered here use one tire size: 550-17. That size applies to the 1933 Pontiac 8 Cyl. model and mounts on a 17-inch wheel. Because there is only one fitment size in this range, buyers do not need to sort through multiple diameters or alternate section widths at the year-and-make level.
The practical choice comes down to selecting the right sidewall style rather than choosing between different sizes. A blackwall gives a restrained driver-quality look, while wide whitewall and double-whitewall versions create a more formal pre-war presentation. Before ordering, compare the tire size on the car now with the wheel itself so the restoration direction and the actual hardware agree.
What does 550-17 mean on a 1933 Pontiac tire?
On a 1933 Pontiac, 550-17 is a numeric bias-ply size. The 5.50 refers to the tire’s nominal section width, and the 17 refers to the wheel diameter in inches. This is an older sizing convention used widely in the pre-war period, so it does not read like a modern metric radial size.
Understanding that code helps you avoid mixing generations of tire sizing when comparing options. A buyer looking at 550-17 should expect a traditional bias-ply construction and period-correct proportions, not a modern metric interpretation. If the car is being judged or restored with era accuracy in mind, staying within the proper numeric bias-ply format matters just as much as choosing the correct sidewall treatment.
Do all 1933 Pontiac models use the same tire size?
Yes. The 1933 Pontiac model covered here uses the same 550-17 tire size throughout this year-and-make range. That simplifies fitment because you are not choosing among model-specific tire diameters or separate front and rear fitments at this level.
Even with one shared size, the final result can still look quite different depending on sidewall style. Owners pursuing a conservative driver look may lean toward blackwalls, while a fuller whitewall treatment better suits many pre-war restoration themes. Once you confirm that your car is within the 1933 Pontiac 8 Cyl. range, the next step is matching appearance expectations rather than hunting for a different tire size.
Buying the Right Tire
What sidewall styles are available for 1933 Pontiac tires?
1933 Pontiac tires in 550-17 are available in Blackwall, Wide Whitewall, and Double-Whitewall styles. All three are offered in bias-ply construction, so the fitment stays the same while the visual character changes. That gives owners room to tailor the car’s finished stance and presentation without moving away from the correct size.
For many pre-war American restorations, whitewall styling is often the more formal and era-appropriate visual choice, especially on a car positioned above the lowest-priced field. Blackwalls, however, can suit a more restrained driver restoration or a car finished in a less ornate style. If show presentation matters, compare the sidewall look to period photos, club guidance, and the car’s trim level before deciding.
What brands make tires for 1933 Pontiac vehicles?
BFGoodrich makes the 550-17 tires available for 1933 Pontiac vehicles in this fitment group. The available versions remain within one classic bias-ply family, with the main difference centered on sidewall appearance rather than brand-to-brand construction changes. That keeps the selection process focused and historically coherent for a pre-war Pontiac owner.
A single-brand offering can actually simplify the choice because you are comparing visual presentation within one established classic line instead of trying to reconcile different brand philosophies. The decision then becomes whether your car is being finished as a straightforward touring restoration or a more dressed presentation with whitewalls. Either way, confirm the 550-17 size first, then choose the sidewall style that fits your goals.
What is the difference between BFGoodrich blackwall, wide whitewall, and double-whitewall tires for the 1933 Pontiac?
For the 1933 Pontiac, the BFGoodrich 550-17 options share the same bias-ply construction, the same 17-inch rim diameter, and the same listed weight. The main difference is sidewall treatment: one version is Blackwall, one is a 3.25-inch Wide Whitewall, and one is a 3.25-inch Double-Whitewall. The tire family itself remains consistent across those versions.
That means the choice is primarily aesthetic and restoration-driven rather than a change in basic fitment. A blackwall usually reads more understated, while a wide whitewall gives the car a fuller, more luxurious period presence. A double-whitewall offers an even more distinctive pre-war look, so owners should choose according to the car’s trim, finish, and the way they want the completed Pontiac to present.
Fitting & Setup
What rim width do 1933 Pontiac tires require?
1933 Pontiac fitments here use a 550-17 tire on a 17-inch wheel, but no rim width range is specified within this tire group. The key confirmed fitment point is the 17-inch rim diameter, which must match the wheel before any tire is selected. That keeps the basic mounting dimension straightforward even though width details should still be checked directly on the car.
Before finalizing a set, verify the actual wheel dimensions and condition, especially on a pre-war vehicle that may have had replacements or restoration work over the years. Old wheels can differ from what the car originally left the factory with, and that matters for safe mounting and proper profile. If there is any doubt, have the wheels inspected by a shop experienced with vintage bias-ply applications.
Do 1933 Pontiac tires require inner tubes?
1933 Pontiac 550-17 tires are offered here without tube-type or tubeless markings in the tire size itself, so tube requirements should be confirmed against the wheel design and the specific tire being considered. On many pre-war applications, original wheels and restoration practices often lead owners to run tubes even when selecting newly manufactured reproduction tires. The wheel construction matters just as much as the tire.
The smartest approach is to inspect whether the car retains original-style wheels, what condition the rims are in, and whether the product you are considering carries any specific tube guidance. A marque specialist or vintage tire installer can help match the setup to the wheel correctly. That step is especially worthwhile on a 1933 Pontiac, where age and prior restoration choices can affect how the tire should be installed.
Can the original 1933 Pontiac wheels be used with all 1933 Pontiac tire options?
Yes, the available 1933 Pontiac tire options in this fitment group all use the same 550-17 size and the same 17-inch rim diameter. Since the blackwall, wide whitewall, and double-whitewall versions stay within that common size, the wheel diameter requirement does not change between them. The selection is visual rather than a different wheel-size conversion.
That said, original wheels still need to be checked for straightness, bead-seat condition, and general structural sound before mounting any new tires. Pre-war wheels can have age-related wear, corrosion, or old repairs that are not obvious until they are inspected closely. Keeping the original wheels is often part of the car’s appeal, but they should be evaluated as carefully as the tires themselves.
Maintenance, Storage & Longevity
How should I store a 1933 Pontiac when the tires are fitted?
A 1933 Pontiac should be stored in a cool, dry, dark space away from direct sunlight, electric motors, furnaces, and other ozone-producing equipment that can accelerate sidewall aging. Bias-ply tires also benefit from maintaining proper inflation during storage because they can develop temporary flat spots more readily than modern radials after long static periods. Clean, dry floors and stable temperature conditions help preserve both the tires and the wheels.
If the car will sit for an extended period, move it occasionally or place it on stands so the full vehicle weight is not resting in one spot on the tires for months at a time. Keep solvents, fuel vapors, and moisture away from the tires and sidewalls. A little planning in storage pays off when the Pontiac is ready to return to the road without vibration, cracking, or avoidable aging damage.
How long do tires on a 1933 Pontiac typically last?
On a low-use collector car like a 1933 Pontiac, tire life is usually governed more by age than by mileage. A good rule is to begin evaluating classic-car tires closely once they are around five to seven years old and to treat about ten years as a serious replacement consideration, even if the tread still looks usable. The DOT date code on the tire helps establish age.
A pre-war Pontiac may spend much of its life indoors and travel only modest distances, which can make old tires look better than they really are. Sidewall condition, storage history, and the way the tire holds pressure matter more than odometer habits. If the car is seeing tours, shows, or regular seasonal driving, age-based replacement planning is a much safer strategy than waiting for visible tread wear alone.
How often should tires on a 1933 Pontiac be inspected?
Tires on a 1933 Pontiac should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, irregular wear, and signs that the tire has been run underinflated or has shifted on the wheel. On a collector vehicle, even long periods of sitting can create issues that are easy to miss if the car is only checked casually.
A more thorough inspection every season is a smart habit, especially if the car is shown or driven only occasionally. Check air retention over time, examine the valve stems, and make sure the spare is still usable as part of the overall package. Frequent visual checks are one of the simplest ways to protect an older Pontiac from preventable roadside problems.
Restoration & Authenticity
What tires were originally fitted to the 1933 Pontiac 8 Cyl.?
A 1933 Pontiac 8 Cyl. would have been fitted in the bias-ply era, and the correct size for the model covered here is 550-17. That makes a bias-ply reproduction the appropriate starting point for owners aiming to stay faithful to the car’s original type of tire construction. Original-equipment branding can vary by market and history, so the strongest fitment anchor is the size and construction type.
For restoration work, staying with a 550-17 bias-ply tire preserves the proportions and character expected on a pre-war Pontiac. The remaining decision is the sidewall style that best aligns with your car’s appearance and the standards of the event where it may be shown. If authenticity at the trim or regional-delivery level matters, marque clubs and period literature are the right places to refine the final presentation.
Does correct tire fitment matter for showing a 1933 Pontiac?
Yes, correct tire fitment matters on a 1933 Pontiac because judges and knowledgeable enthusiasts notice size, construction type, and sidewall appearance quickly. A 550-17 bias-ply tire matches the era correctly, while a visibly modern construction or an obviously out-of-period sidewall treatment can distract from an otherwise careful restoration. Tires contribute heavily to stance, wheelwell fill, and the car’s overall visual authenticity.
That does not mean every event applies the same standards, but serious pre-war judging typically rewards period-correct choices. A buyer preparing a show car should compare the sidewall look to event expectations as carefully as the paint, trim, and wheel finish. Club guidance is especially helpful when deciding whether a blackwall, wide whitewall, or double-whitewall best suits the way the car is being presented.
What is the difference between BFGoodrich blackwall, wide whitewall, and double-whitewall tires for the 1933 Pontiac in restoration terms?
In restoration terms, the BFGoodrich blackwall, wide whitewall, and double-whitewall 550-17 tires for a 1933 Pontiac all preserve the correct basic size and bias-ply construction. The difference lies in how formal, restrained, or ornate the finished car appears once the tires are mounted. Because the listed construction and fitment stay the same, the restoration effect comes from sidewall presentation rather than a mechanical change.
That makes sidewall choice an important visual decision for a pre-war Pontiac owner. A blackwall can suit a simpler, less embellished presentation, while a wide whitewall often better matches the elegant look many restorers want from an early-1930s American car. A double-whitewall is the most distinctive statement of the three and should be chosen when it complements the specific appearance theme of the restoration.
Safety & Road Use
Are 1933 Pontiac tires safe for highway driving?
1933 Pontiac tires in this fitment group are bias-ply tires, and that means they should be driven with the expectations appropriate to period-style construction. Bias-ply tires can serve well on a properly prepared collector car, but they do not deliver the same steering feel or lane-tracking behavior many drivers expect from modern radials. On a car of this age, the vehicle’s own brakes, suspension, and general mechanical condition are often just as important as the tires themselves.
A sound 1933 Pontiac can certainly be enjoyed on public roads, but the driver should allow for longer stopping distances, slower steering response, and greater sensitivity to road surface changes than a modern car. Highway use should be approached with a conservative mindset that respects both the tire type and the rest of the chassis. Regular inspection, proper inflation, and realistic speeds matter more than treating the car like a modern commuter vehicle.
What inflation pressure should I use for 1933 Pontiac tires?
The available 1933 Pontiac 550-17 tire listings here do not include a stated maximum load and pressure figure, so inflation should be set with reference to the original vehicle guidance and the current tire manufacturer’s recommendations for that exact product. Pressure on a vintage vehicle is never something to guess or transfer casually from another size. The right setting depends on the specific tire and the vehicle’s original operating requirements.
Start with the owner’s manual, factory service information, or trusted marque references for the car’s intended pressure range, then compare that with any guidance supplied for the reproduction tire itself. Use a quality gauge and check pressures when the tires are cold. Small pressure errors can change how a bias-ply Pontiac steers and rides, so consistent inflation matters more than many owners realize.
What should I check before taking a 1933 Pontiac on a longer drive?
Before a longer drive in a 1933 Pontiac, inspect each tire for visible cracking, cuts, bulges, tread separation, embedded debris, and signs of uneven wear. Check cold inflation pressure, look over the valve stems, and make sure the spare is in usable condition along with the tools needed to change it. Tire condition should be treated as one part of a broader pre-drive inspection on any pre-war car.
A longer outing is also the right time to confirm wheel security, brake operation, steering response, and general fluid condition so the car is not relying on the tires to compensate for unrelated mechanical issues. Bias-ply tires reward a cautious, prepared approach rather than a rushed departure. Spending a few extra minutes in the garage often makes the difference between a pleasant touring day and an avoidable roadside interruption.
