The 1958 Oldsmobile 88 Series came from a moment when Detroit styling was growing lower, wider, and more expressive, and tire appearance played a major role in the car’s overall presentation. On this model, the tire decision is centered on one primary size: 900-14, a bias-ply fitment on a 14-inch rim. That keeps the focus less on sorting through multiple fitments and more on choosing the right look within the correct size. Available 900-14 options include wide whitewall and narrow whitewall treatments in BFGoodrich’s Silvertown Classic Bias Ply line. For a restoration-minded owner, the key is balancing the right size, the right period-style sidewall, and the actual wheel setup on the car.
Which Tire Size Is Right for The 1958 Oldsmobile 88 Series
The 1958 Oldsmobile 88 Series uses one primary tire size: 900-14. It is a bias-ply fitment built for a 14-inch rim, and the covered w/Air and Super 88 w/Air sub-models share that same sizing. With fitment staying consistent, the real choice becomes selecting the sidewall style and product presentation that best suits the car’s restoration goals and road-use plans.
The 900-14 size uses a vintage numeric bias-ply format, where the leading number refers to the tire’s nominal section width in inches and the final number identifies the rim diameter. On the 1958 Oldsmobile 88 Series, this is a traditional bias-ply fitment that matches the period character of the car and its original tire profile. Available choices in this size include BFGoodrich Silvertown Classic Bias Ply tires with either a 2.25-inch wide whitewall or a 1.00-inch narrow whitewall. That makes 900-14 the right starting point for owners who want correct-size fitment while refining the car’s visual presentation.
Tire fitment is straightforward across the covered 1958 Oldsmobile 88 Series sub-models. The w/Air and Super 88 w/Air configurations share the same primary tire size, so the main decision is choosing the right bias-ply sidewall style and confirming the wheels on the car remain true to that setup.

These 1958 Oldsmobile 88 Series FAQs focus on the 900-14 tire size, 14-inch rim fitment, bias-ply construction, sidewall appearance choices, and the key wheel, condition, and maintenance checks to make before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 1958 Oldsmobile 88 Series?
The 1958 Oldsmobile 88 Series uses a 900-14 tire size. This is a numeric bias-ply size built for a 14-inch rim, and it is the primary fitment for the covered application on this vehicle.
That makes the first step fairly simple: start with 900-14, then choose the tire that matches the car’s appearance goals and wheel setup. If the car has been changed over to aftermarket wheels or a different wheel diameter at some point, confirm the actual rim size on the car before selecting a replacement tire.
What size rim does a 1958 Oldsmobile 88 Series use?
The 1958 Oldsmobile 88 Series uses a 14-inch rim with its 900-14 tire size. Available 900-14 products in this fitment are built around that 14-inch rim diameter and suit rim widths in the 6.00- to 7.00-inch range.
Rim diameter is the non-negotiable measurement to verify first, especially on an older car that may have changed wheels over the years. After confirming the wheel is 14 inches in diameter, check the wheel width as well so the selected 900-14 tire matches both the vintage size and the wheel it will actually be mounted on.
Do all 1958 Oldsmobile 88 Series sub-models use the same tire size?
The covered 1958 Oldsmobile 88 Series w/Air and Super 88 w/Air sub-models use the same 900-14 bias-ply tire size. That means sub-model identification does not create a separate primary tire-size decision within this application.
Even with shared fitment, it still helps to verify the car’s actual wheel setup before replacing tires. Many collector cars have seen wheel changes during restoration or regular use, so confirming the 14-inch rim diameter and overall wheel condition prevents confusion and keeps the replacement choice aligned with the car as it sits today.
Choosing the Right Tire
What should I consider when choosing a 900-14 tire for a 1958 Oldsmobile 88 Series?
Start with the correct size and construction: 900-14 in a bias-ply design. From there, the main decision is how you want the car to look, since available options in this size use the same BFGoodrich Silvertown Classic Bias Ply series but differ in sidewall treatment.
A wide whitewall gives the car a fuller late-1950s visual presence, while a narrower whitewall creates a cleaner and slightly more restrained presentation. It also makes sense to confirm the wheel is within the tire’s supported width range and to think about whether the car is being finished for restoration display, casual driving, or a blend of both.
What sidewall styles are available for 1958 Oldsmobile 88 Series tires?
The available 900-14 tires for the 1958 Oldsmobile 88 Series include both wide whitewall and narrow whitewall styles. In this fitment, BFGoodrich offers a 2.25-inch whitewall and a 1.00-inch whitewall within the same Silvertown Classic Bias Ply series.
That choice is mostly about appearance rather than basic fitment, since both stay within the correct size and bias-ply construction. Owners trying to capture a fuller period-style look often focus closely on whitewall width, while drivers who want a more understated visual balance may prefer the narrower band on a large 1958 body.
How do I choose between the available 900-14 tires for a 1958 Oldsmobile 88 Series?
The available 900-14 choices are closely related in construction, brand, and tire series, so the biggest difference is sidewall presentation. Both options are BFGoodrich Silvertown Classic Bias Ply tires with the same maximum load capacity of 1860@32 psi and the same 14-inch rim diameter.
Since the technical fitment stays very similar, the decision usually comes down to the look that best suits the car and the way it is being restored or maintained. It is still worth checking the wheel width, overall wheel condition, and the condition of other chassis components so the new tires are being matched to a sound setup.
Restoration & Appearance
Which tire should I choose for a period-style 1958 Oldsmobile 88 Series?
A period-style starting point for a 1958 Oldsmobile 88 Series is the correct 900-14 bias-ply size. Staying with the proper size and vintage construction preserves the visual proportions expected on a large late-1950s Oldsmobile and keeps the tire choice aligned with the car’s original era.
After that, appearance comes down to the sidewall treatment that best suits the build. A restoration-oriented owner may compare wide whitewall versus narrow whitewall based on the car’s trim, color, and intended presentation, while anyone pursuing exact originality should also consult marque-specific historical references before making a final cosmetic decision.
How does tire construction affect the appearance of a restored 1958 Oldsmobile 88 Series?
On a restored 1958 Oldsmobile 88 Series, bias-ply construction contributes strongly to the car’s authentic period-style stance and side profile. The 900-14 fitment used here reflects a traditional vintage sizing approach, so the tire’s shape and presentation play a visible role in the overall look of the vehicle.
That matters because a large 1958 body can look noticeably different depending on tire profile and sidewall style. Keeping the correct bias-ply size helps preserve the visual relationship between the wheel opening, wheel diameter, and whitewall treatment, which is often just as important to restoration-minded owners as simple rolling fit.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1958 Oldsmobile 88 Series?
Yes. Even though the primary fitment is 900-14 on a 14-inch rim, wheel or suspension changes can alter what actually works on the car. Aftermarket wheels, altered offsets, lowered ride height, replacement springs, or brake conversions can all change clearance and mounting requirements.
That is why the car itself should be checked before replacing tires, especially on an older vehicle with an unknown history. Confirm the actual wheel diameter and width, then inspect steering and fender clearance at full lock and full suspension travel so the selected tire matches the Oldsmobile’s current setup rather than an assumed one.
What should I inspect before driving a 1958 Oldsmobile 88 Series on new tires?
Begin with the basics: confirm the wheels are the correct 14-inch diameter, inspect them for damage or corrosion, and make sure the tires are mounted and inflated properly. It also helps to look over the valve stems, lug hardware, and overall condition of the suspension and steering components.
A sound tire installation works best when the rest of the chassis is ready for road use too. Before the first meaningful drive, check for rubbing, listen for unusual noises, and verify that the car tracks normally. On a collector vehicle, a cautious short drive is a smart way to catch fitment or mechanical issues early.
How should 900-14 tires on a collector 1958 Oldsmobile 88 Series be maintained?
Collector-car tires should be inspected regularly even when the car is driven only occasionally. Keep the 900-14 tires at the proper pressure for the application, and look closely for sidewall cracking, cuts, bulges, uneven wear, and slow air loss before and after periods of storage.
Storage conditions matter almost as much as mileage on a low-use Oldsmobile. A cool, dry space away from prolonged sunlight, electric motors, and ozone sources helps preserve the rubber, while moving the car periodically and checking the wheels and tread for age-related issues helps keep it ready for safe, occasional road use.
