1957 Oldsmobile sat squarely in the height of Detroit’s chrome-and-horsepower era, offering everything from mainstream full-size cars to more upscale and body-specific variations within the 88, Super 88, and 98 families. For buyers sorting out tires, the important detail is that 1957 Oldsmobile spans five model groups and two bias-ply sizes, with some models able to use either size while the convertible and wagon applications center on the larger option. Because both sizes mount on 14-inch wheels, the real question is usually which model you have and whether you need the narrower or wider original-style fitment before you choose a tire.
Which Tire Size Is Right for Your 1957 Oldsmobile
Two tire sizes are used across 1957 Oldsmobile models, and they do vary by model rather than applying universally across the whole lineup. Since both are bias-ply 14-inch sizes, the decision is less about construction type and more about matching the correct size to your specific model and wheel width. Understanding that distinction before choosing a product saves time and helps you land on the right fit for your car.
Year(s): 1957|Fit(s): 88 Series, 98 Series, Super 88|Construction: Bias Ply|Rim: 14 in
850-14 is a numeric bias-ply size, with 8.50 indicating nominal section width and 14 indicating the wheel diameter in inches. BFGoodrich offers this size with both wide whitewall and narrow whitewall styling, and the available products are bias-ply throughout. This size is specific to the 1957 Oldsmobile 88 Series, 98 Series, and Super 88 rather than the full model range. It is the right path for owners focused on staying with the original-style bias-ply fitment used on those applications.
Year(s): 1957|Fit(s): 88 Series, 98 Series, Super 88, Super 88 & 98 Convertible, Super 88 & 98 Wagon|Construction: Bias Ply|Rim: 14 in
900-14 is a numeric bias-ply size, with 9.00 indicating nominal section width and 14 indicating the wheel diameter in inches. BFGoodrich offers this size in both wide whitewall and narrow whitewall versions, and the available products remain bias-ply across the board. This is the only size used on the 1957 Oldsmobile Super 88 & 98 Convertible and Super 88 & 98 Wagon, while also appearing on 88 Series, 98 Series, and Super 88 models. It suits owners who need the larger original-style fitment tied to those heavier or body-specific applications.
Because both sizes use a 14-inch wheel, either size can typically be mounted on the same diameter wheel when the wheel's width matches the tire's approved range.
1957 Oldsmobile Models
Five 1957 Oldsmobile model groups are covered here, ranging from core full-size series cars to body-specific convertible and wagon applications. Tire size is not identical across the lineup, so identifying the exact model matters before choosing between 850-14 and 900-14. Select your model below to narrow the fitment history and see the tires tied to that application.
1957 Oldsmobile 88 Series
The 1957 Oldsmobile 88 Series was the make's full-size entry point, blending Rocket V8 image with broad mainstream appeal in the late-'50s market. Its tire fitment spans both 850-14 and 900-14, and both sizes mount on 14-inch wheels, so the key is matching the car's actual wheel width and original-style setup rather than chasing a different construction type.
The 1957 Oldsmobile 98 Series represented the division's more upscale full-size offering, with a longer, more formal character than the junior series cars. It also uses 14-inch wheel fitments, with both 850-14 and 900-14 appearing across the model group, making correct size selection more important than any change in tire construction.
The 1957 Oldsmobile Super 88 sat between the 88 and 98 in Oldsmobile's hierarchy, carrying much of the division's performance-luxury identity in one of its most recognizable eras. This model group uses 14-inch tires and can be found with either 850-14 or 900-14, so owners should confirm which size matches the car's wheel and intended restoration presentation.
The 1957 Oldsmobile Super 88 & 98 Convertible applications reflect the glamorous, high-style side of the division's late-'50s lineup, where appearance and proper stance are a big part of the car's presence. These models use 900-14 on 14-inch wheels, making the larger bias-ply size the relevant fitment path for convertible owners.
The 1957 Oldsmobile Super 88 & 98 Wagon brought family-car practicality into Oldsmobile's full-size range without losing the division's premium look and feel. Wagon applications use 900-14 on 14-inch wheels, so the larger bias-ply size is the one to follow when restoring the correct stance and sidewall look.
Four products are available across two tire sizes for 1957 Oldsmobile vehicles. The 850-14 size includes two BFGoodrich bias-ply choices in wide whitewall or narrow whitewall, and the 900-14 size includes two BFGoodrich bias-ply choices in the same sidewall styles.
These FAQs sort out how 850-14 and 900-14 fit across the 1957 Oldsmobile range, how whitewall options differ by size, and what to check for storage, setup, and longer road use on a collector-era full-size car.
Size Basics & Fitment
What tire sizes fit 1957 Oldsmobile vehicles?
1957 Oldsmobile vehicles use two tire sizes: 850-14 and 900-14. The 88 Series, 98 Series, and Super 88 can use either 850-14 or 900-14, while the Super 88 & 98 Convertible and Super 88 & 98 Wagon use 900-14 only. Both sizes fit 14-inch wheels. For available products, 850-14 is paired with a 5.50 to 6.00 inch rim width range, while 900-14 is paired with a 6.00 to 7.00 inch rim width range.
That means year and make alone are not always enough to choose the right tire for a 1957 Oldsmobile. Owners of an 88 Series, 98 Series, or Super 88 should confirm which size belongs on the car before ordering, especially if the wheels may have been changed during a past restoration. Convertible and wagon owners have a simpler path because 900-14 is the relevant size, but wheel width should still be checked against the actual rim.
What does 850-14 mean on a 1957 Oldsmobile tire?
On a 1957 Oldsmobile, 850-14 is a numeric bias-ply tire size. The 8.50 refers to the nominal section width in inches, and the 14 refers to the wheel diameter in inches. It is not a modern metric radial designation, and it does not include an aspect ratio in the way a later P-metric tire would. In the available fitments, 850-14 appears on 88 Series, 98 Series, and Super 88 models.
That decoding matters because a modern buyer may assume every two-number size works like a later radial code, but 1950s numeric sizing follows older bias-ply conventions. For a 1957 Oldsmobile, 850-14 should be treated as an original-style fitment category, not as a direct interchangeable equivalent to a modern metric tire. If your car is one of the models that can use either listed size, confirm the wheel width and restoration target before settling on 850-14.
Do all 1957 Oldsmobile models use the same tire size?
No, not all 1957 Oldsmobile models use the same tire size. Three model groups—the 88 Series, 98 Series, and Super 88—span both 850-14 and 900-14, while the Super 88 & 98 Convertible and Super 88 & 98 Wagon use 900-14 only. All of those sizes remain 14-inch fitments, so the variation is in tire width category rather than wheel diameter.
That difference is important when a car is identified only as a 1957 Oldsmobile without the specific series or body style. A convertible or wagon owner should be looking directly at 900-14 options, while owners of the other full-size series need to determine which of the two sizes matches their car. Checking the actual tires on the car, the wheel width, and restoration records usually clears up the question quickly.
Buying the Right Tire
Should I choose the 850-14 or the 900-14 for my 1957 Oldsmobile?
The right choice for a 1957 Oldsmobile depends first on model application and wheel width, not on a bias-ply versus radial decision, because both listed sizes are bias-ply. The 88 Series, 98 Series, and Super 88 can be associated with either 850-14 or 900-14, while the Super 88 & 98 Convertible and Super 88 & 98 Wagon use 900-14 only. The available rim width ranges also differ: 850-14 fits 5.50 to 6.00 inch rims, and 900-14 fits 6.00 to 7.00 inch rims.
For most buyers, that means the first question is whether the car should wear the narrower or larger original-style size tied to its specific application. If the car is a convertible or wagon, 900-14 is the clear path. If it is an 88 Series, 98 Series, or Super 88, compare the wheels on the car and your restoration goals before choosing, since both sizes appear within those model groups.
What sidewall styles are available for 1957 Oldsmobile tires?
1957 Oldsmobile tires are available in both wide whitewall and narrow whitewall styles in each listed size. The 850-14 offerings include a 2.25 inch whitewall and a 1.00 inch whitewall, and the 900-14 offerings mirror that same choice. All of those options are BFGoodrich bias-ply tires, so the sidewall decision is mainly about visual presentation rather than a change in construction.
For a 1957 Oldsmobile, sidewall width has a strong effect on the car's finished look because whitewall proportion is a major styling cue on late-1950s American cars. A wide whitewall generally suits a more formal, period-correct presentation, while a narrow whitewall creates a slightly cleaner, less dressy appearance. Owners building to judged standards should compare their choice with period photos, factory literature, and the expectations of the club or event where the car will be shown.
What brands make tires for 1957 Oldsmobile vehicles?
BFGoodrich is the listed brand available for 1957 Oldsmobile tire sizes here, covering both 850-14 and 900-14. Within each size, the tires are offered as Silvertown Classic Bias Ply products with either a wide whitewall or narrow whitewall sidewall treatment. There is no change in construction between the brand options for these fitments because the available products are bias-ply throughout.
That gives a 1957 Oldsmobile owner a fairly straightforward choice structure: first confirm the correct size, then choose the whitewall width that matches the desired look of the car. Because the product family stays consistent between the two sizes, the buying decision is more about correct application and appearance than comparing multiple construction philosophies. It also makes it easier to keep a matching visual style if you are restoring more than one car within the 1957 Oldsmobile range.
Fitting & Setup
What rim width do 1957 Oldsmobile tires require?
The available 1957 Oldsmobile 850-14 tires are matched to a 5.50 to 6.00 inch rim width range, and the available 900-14 tires are matched to a 6.00 to 7.00 inch rim width range. Both sizes use a 14-inch wheel diameter. That means wheel width is one of the key setup differences between the two sizes, even though the wheel diameter stays the same.
A buyer comparing 850-14 and 900-14 should check the actual wheel on the car before making a final choice. That is especially important for 88 Series, 98 Series, and Super 88 models, since those model groups appear with both sizes. If the car has replacement wheels or an older restoration, measuring the installed rim can prevent choosing a tire that is correct in diameter but wrong for the wheel width range.
Do 1957 Oldsmobile tires require inner tubes?
The listed 1957 Oldsmobile products do not carry tube-type or tubeless markings in their size descriptions, so the practical decision should be made by the wheel itself and the exact tire's sidewall marking. Both 850-14 and 900-14 are offered as bias-ply tires, and many collector-era wheels can require tube use depending on their design, condition, and whether they were built for tubeless service.
For a 1957 Oldsmobile, the safest approach is to inspect the wheels before tire installation rather than assume every 14-inch full-size wheel is set up the same way. Rust in the bead seat area, wheel repairs, or an earlier non-original rim can all affect whether tube use makes sense. If you are preserving original wheels, have a tire professional or marque specialist review the wheel condition and confirm the correct setup before mounting new tires.
Can the original 1957 Oldsmobile wheels be used with both tire sizes?
Original 1957 Oldsmobile wheels can be used with both listed tire sizes only if the wheel matches the required diameter and width range for the tire being installed. Both 850-14 and 900-14 are 14-inch sizes, so there is diameter compatibility across the range. The difference is width: 850-14 is paired with 5.50 to 6.00 inch rims, while 900-14 is paired with 6.00 to 7.00 inch rims.
That overlap at 6.00 inches means some wheels may sit at the crossover point, but it should not be assumed that every original wheel is equally suitable for both sizes. This matters most on 88 Series, 98 Series, and Super 88 cars, where both sizes appear in the fitment range. Before switching from one size to the other, verify the wheel's actual width and condition so the tire choice stays within the approved mounting range.
Maintenance, Storage & Longevity
How should I store a 1957 Oldsmobile when the tires are fitted?
A 1957 Oldsmobile should be stored in a cool, dry, dark space with the tires protected from sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Because the available fitments here are bias-ply tires, extended static storage can encourage flat-spotting more readily than many later radial designs. Clean floors, stable temperatures, and proper inflation also help reduce stress on the casing during long idle periods.
Owners who store a 1957 Oldsmobile for months at a time should move the car periodically or use properly placed stands if the storage plan and suspension setup make that appropriate. The goal is to reduce long-term weight concentration on one contact patch without creating new chassis problems. Whitewall tires also benefit from careful cleaning and covering, since cosmetic aging can become visible long before the tread is truly worn out.
How long do tires on a 1957 Oldsmobile typically last?
On a 1957 Oldsmobile, tire age usually matters more than mileage because collector cars often accumulate limited road use. A good rule is to begin evaluating tires closely once they are five to seven years old and to consider replacement as they approach about ten years, even if the tread still looks healthy. The DOT date code on the tire is the quickest way to establish age when service history is unclear.
That timeline is especially useful for a 1957 Oldsmobile that spends much of its life in a garage, where an owner may be tempted to trust appearance alone. Sidewall cracking, hardening, vibration, and repeated pressure loss can all show up before the tread is worn down in any meaningful way. If the car is driven only seasonally, age-based replacement planning is usually more realistic than trying to estimate life from miles traveled.
How often should tires on a 1957 Oldsmobile be inspected?
Tires on a 1957 Oldsmobile should be inspected before every drive and again before any longer trip or event. Look closely for sidewall cracks, cuts, bulges, uneven wear, and signs that the tire has been losing pressure while parked. Pressure checks matter just as much as visual checks on a collector car, since a vehicle that sits for long periods may not reveal a slow leak until the next outing.
A more thorough inspection several times a year is also smart, particularly if the car is shown, stored, and then driven in cycles rather than used weekly. Include the spare if the car still carries one, because an old spare often gets overlooked until it is needed. If your wheel and tire setup uses tubes, inspect the valve stems and overall air retention carefully, since tube-related issues can show up as gradual pressure loss rather than obvious tread problems.
Restoration & Authenticity
What tires were originally fitted to the 1957 Oldsmobile 88 Series?
A 1957 Oldsmobile 88 Series would have been equipped in the bias-ply era, and the listed fitments for the model group are 850-14 and 900-14. That aligns with normal American full-size practice for the period, when bias-ply construction was standard and whitewall presentation was an important part of the car's appearance. No original-equipment brand should be assumed from that alone, but the construction type and size family are consistent with what buyers expect for a proper late-1950s restoration.
For an exact restoration, owners should confirm how their specific car was configured before deciding between the two sizes that appear within the 88 Series range. Factory literature, build records when available, and marque-club guidance are the best ways to settle market- or body-specific questions. Once the size is confirmed, the remaining visual decision usually comes down to choosing the whitewall width that best matches the car's intended presentation.
Does correct tire fitment matter for showing a 1957 Oldsmobile?
Correct tire fitment matters on a 1957 Oldsmobile because judges and knowledgeable enthusiasts often notice the relationship between tire size, construction, and sidewall style right away. On a late-1950s American full-size car, an incorrect size or a whitewall style that clashes with the era can change the stance and visual balance of the whole vehicle. Since the listed 1957 Oldsmobile fitments are bias-ply sizes, staying within those original-style categories supports an authentic appearance.
What counts as acceptable can vary by event, club, and judging standard, so restoration-minded owners should compare their tire choice to the specific rules of the venue where the car will be shown. Convertible, wagon, and upscale series cars may also draw closer scrutiny because their trim and proportions make tire presentation more visible. If you are building for points, confirm both the size and the whitewall look before the car reaches final detailing.
What is the difference between the wide whitewall and narrow whitewall tires for the 1957 Oldsmobile?
For the 1957 Oldsmobile, the practical difference between the available whitewall versions is visual rather than structural. Both 850-14 and 900-14 are offered as BFGoodrich Silvertown Classic Bias Ply tires in a 2.25 inch wide whitewall and a 1.00 inch narrow whitewall. Load rating, inflation figure, and basic construction stay the same within each size, so the tire's appearance is the main variable.
That makes the choice especially important on a prominent styling year like 1957, where the side profile of the car plays a big role in how authentic it feels. A wide whitewall generally emphasizes the formal, upscale look associated with many American cars of the period, while a narrow whitewall tones that effect down. Owners chasing factory-style presentation should compare the finished look against period photos and club expectations for their exact model.
Safety & Road Use
Are 1957 Oldsmobile tires safe for highway driving?
The available 1957 Oldsmobile tires are bias-ply designs, and no speed rating is shown in the listed size markings for either 850-14 or 900-14. A properly maintained new bias-ply tire can be used for normal road service within the overall limits of the vehicle, but a 1957 Oldsmobile should always be driven with the expectations appropriate to a full-size 1950s car. Braking, steering feel, suspension condition, and road crown sensitivity often influence real-world highway comfort as much as the tire itself.
Highway safety on a 1957 Oldsmobile depends on the whole package: fresh tires, correct inflation, solid wheel condition, and a chassis that has been inspected recently. Bias-ply construction also behaves differently from later radial designs, especially in tracking and transient response, so a driver should allow a short familiarization period after installation. If the car has been dormant or recently restored, a cautious local shakedown is smarter than making the first drive a long interstate run.
What inflation pressure should I use for 1957 Oldsmobile tires?
The available 1957 Oldsmobile 850-14 tires carry a maximum load of 1740 pounds at 32 psi, and the available 900-14 tires carry a maximum load of 1860 pounds at 32 psi. Those numbers are the tire's rated load-and-pressure figures, not necessarily the day-to-day pressure your specific 1957 Oldsmobile should be run at. Factory operating pressure should be checked against the owner's manual or period service information for the exact model and use.
That distinction matters because maximum rated pressure is not a blanket instruction to inflate every collector car tire to that number in regular service. A full-size 1957 Oldsmobile may call for a lower working pressure depending on model, load, and ride tuning. Use the correct pressure for the car, then recheck it after installation and during seasonal temperature swings so the tire's wear, handling, and ride stay consistent.
What should I check before taking a 1957 Oldsmobile on a longer drive?
Before a longer drive in a 1957 Oldsmobile, inspect all four tires for sidewall cracking, weather checking, tread damage, bulges, and any sign of uneven wear. Confirm inflation pressures, inspect valve stems, and make sure the spare is usable if the car still carries one. Since these are 14-inch bias-ply fitments, it is also wise to look for any vibration, pull, or flat-spot tendency during the first few miles after the car has been parked.
Tire checks should be part of a broader pre-trip inspection on a 1957 Oldsmobile, not the only step. Wheel fastener torque, brake operation, steering play, fluid levels, cooling-system condition, and lighting all matter just as much on an older full-size car headed out for distance. If the car has not traveled beyond local drives recently, start with a shorter run close to home before committing to an all-day highway outing.
