The 1933 Oldsmobile 6 Cyl. came from a period when American cars were balancing streamlined styling, improving road manners, and the everyday demands of Depression-era driving. For many collectors, that makes tire choice part mechanical necessity and part visual decision, because the tire has a major effect on stance and period character. This Oldsmobile uses a 550-17 bias-ply tire on a 17-inch rim. Available choices stay within that traditional construction while giving you blackwall, wide whitewall, and double-whitewall presentations in the Silvertown Classic Bias Ply line. The key is selecting the look you want while confirming the wheel and overall chassis setup remain true to the car.
Which Tire Size Is Right for The 1933 Oldsmobile 6 Cyl.
The 1933 Oldsmobile 6 Cyl. uses one primary tire size: 550-17. It is a bias-ply fitment built for a 17-inch rim, and the covered Base sub-model uses the same size. That means the main decision is not choosing between multiple primary sizes, but selecting the right sidewall style and staying with the traditional bias-ply construction that suits the car's era and appearance.
The 550-17 size uses the vintage numeric bias-ply system, where the 550 indicates an approximate 5.50-inch nominal section width and the 17 identifies the rim diameter in inches. On a 1933 Oldsmobile 6 Cyl., this is the traditional bias-ply fitment and keeps the car in the sizing language of its period. Within this size, BFGoodrich offers the Silvertown Classic Bias Ply series in blackwall, wide whitewall, and double-whitewall styles. That gives you room to match the tire's appearance to a more understated driver, a restoration-oriented look, or a more formal pre-war presentation.
Fitment is straightforward for the covered 1933 Oldsmobile 6 Cyl. sub-models. The Base model uses the same primary tire size, so the focus shifts from size selection to choosing the right bias-ply presentation for the car's intended look and use.

Tire Size & Fitment
What tire size fits a 1933 Oldsmobile 6 Cyl.?
The 1933 Oldsmobile 6 Cyl. uses a 550-17 tire size. That is a vintage numeric bias-ply size, and the covered Base sub-model uses the same fitment, so there is one primary size to work from when replacing tires on this car.
The practical question is usually not which primary size fits, but whether the car still has its proper 17-inch wheels and a stock-style setup. On an older collector vehicle, wheel changes, long-term storage, or prior restoration work can affect what is currently mounted, so the actual rim diameter and wheel condition should be confirmed before ordering tires.
What size rim does a 1933 Oldsmobile 6 Cyl. use?
The 1933 Oldsmobile 6 Cyl. uses a 17-inch rim with its 550-17 tire size. The size code and fitment both point to a 17-inch wheel, which is the wheel diameter this tire is built around.
Rim diameter is the first thing to verify on a pre-war car, especially if the vehicle has changed hands or has been off the road for years. A tire marked 550-17 must be matched to a 17-inch wheel, and it also makes sense to inspect the wheel itself for damage, rust, or other issues before mounting fresh tires.
Does the 1933 Oldsmobile 6 Cyl. Base use the same tire size?
Yes. The 1933 Oldsmobile 6 Cyl. Base uses the same 550-17 bias-ply tire size as the covered model fitment. There is no separate primary size for the Base model within this application.
That consistency makes tire shopping simpler, but it still leaves an important choice in appearance. Since the size stays the same, the decision comes down to selecting the sidewall treatment that best suits the car, whether that means a plain blackwall or a more formal whitewall presentation for a restoration-minded finish.
Choosing the Right Tire
What should I consider when choosing a 550-17 tire for a 1933 Oldsmobile 6 Cyl.?
Start with the correct primary size and construction: 550-17 bias-ply on a 17-inch rim. From there, the most meaningful differences are the tire's sidewall style and how closely its overall look matches the character you want for the car.
A blackwall gives the Oldsmobile a simpler, more restrained appearance, while wide whitewall and double-whitewall versions create a more formal pre-war look. It is also wise to inspect the actual wheels and general chassis condition before installation, since an older collector car may have seen decades of repairs, storage, or changes that affect mounting and road use.
What sidewall styles are available for 1933 Oldsmobile 6 Cyl. tires?
For the 1933 Oldsmobile 6 Cyl., 550-17 tires are available in blackwall, wide whitewall, and double-whitewall styles. All of those choices stay within the same bias-ply construction and Silvertown Classic Bias Ply series, so the difference is primarily visual rather than a change in basic fitment.
That makes sidewall style one of the biggest appearance decisions on the car. A blackwall tends to look more understated, while whitewall treatments draw more attention to the wheel opening and can shift the car toward a more dressy, restoration-oriented presentation without changing the tire size itself.
What tire series are available for the 1933 Oldsmobile 6 Cyl.?
The available 550-17 products for the 1933 Oldsmobile 6 Cyl. are in the BFGoodrich Silvertown Classic Bias Ply series. That means the primary variation is not between multiple series, but between different sidewall presentations within the same vintage-style bias-ply family.
For a buyer, that simplifies comparison because the size, construction, and series remain consistent. Instead of sorting through several very different tire lines, attention can stay on the look of the tire and whether the car is being finished as a restrained driver, a more formal restoration, or something in between.
Restoration & Appearance
Which tire should I choose for a period-style 1933 Oldsmobile 6 Cyl.?
A 550-17 bias-ply tire is the period-style starting point for a 1933 Oldsmobile 6 Cyl. because it keeps the car in the traditional construction and size format associated with its era. That preserves the visual character created by the tall, narrow tire profile used on pre-war American cars.
The next choice is sidewall presentation. Blackwall gives a simpler, more restrained look, while wide whitewall or double-whitewall versions create a dressier appearance. If exact restoration accuracy matters down to trim and presentation, it is worth checking marque-specific references or period photos before settling on a particular whitewall treatment.
Does correct tire fitment matter for a 1933 Oldsmobile 6 Cyl. restoration?
Yes, correct tire fitment matters because the tire has a strong effect on a pre-war car's stance, wheel opening proportion, and overall authenticity of appearance. On the 1933 Oldsmobile 6 Cyl., staying with the 550-17 bias-ply format keeps the car visually aligned with the period it came from.
Fitment also affects practicality, not just looks. A car that has the right-size tire on the proper rim is easier to evaluate for clearance, ride height, and general road readiness. Even on a finished restoration, wheel condition, tire age, and mounting details should still be checked carefully before regular driving.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1933 Oldsmobile 6 Cyl.?
Yes. Even though the 1933 Oldsmobile 6 Cyl. uses a 550-17 tire as its primary fitment, changes to wheels, suspension height, brake components, or body clearances can affect what works on the car today. That is especially common on vehicles that have been restored, repaired, or altered over a long lifespan.
A modified setup should be checked at the wheel itself rather than judged by model year alone. Wheel diameter, wheel width, tire-to-fender clearance, and steering clearance all deserve attention before new tires are mounted. On an older car, verifying those details up front is often the difference between a smooth installation and an avoidable fitment problem.
What should I inspect before driving a 1933 Oldsmobile 6 Cyl. on new tires?
Before driving, inspect the wheels, valve hardware, and the mounted tires for proper seating and inflation. It also makes sense to look over the car for obvious suspension looseness, brake issues, or rubbing points, since a fresh set of tires cannot compensate for mechanical problems elsewhere on the vehicle.
Collector cars often spend long periods parked, so a broader road-readiness check is worthwhile. Look for cracking, cuts, bulges, and signs of air loss, then confirm that the tires clear through steering travel and normal suspension movement. A short, cautious test drive followed by another inspection can help catch issues before longer use.
How should 550-17 tires on a collector 1933 Oldsmobile 6 Cyl. be maintained?
550-17 tires on a collector 1933 Oldsmobile 6 Cyl. should be kept properly inflated, inspected regularly, and protected from long exposure to heat, sunlight, moisture, and ozone sources during storage. Since collector vehicles are often driven infrequently, condition matters just as much as tread depth.
Regular checks should include sidewall cracking, flat spotting, cuts, air loss, and any sign that the tire is not wearing or sitting evenly. It also helps to monitor the wheels themselves, because corrosion or damage at the rim can affect tire serviceability. A car that sits for long periods benefits from more frequent inspections before each road outing.
